Description

Cup manufacturing method

The present invention relates to a method of manufacture, and more particularly to a method of making a cup of foam material into a bra.

Generally, the cup made of foam can produce better elasticity, ductility, flexibility and wearing comfort when used, but the structural strength of the foam material is relatively poor. In order to improve the problem of insufficient structural strength of the foam cup, although it can be improved by the covering of the cloth, the covering with the cloth reduces the comfort of the cup.

Referring to Figures 1 and 2, in order to improve the aforementioned deficiency, the new patent number of the certificate No. M240097 provides a cup body 1 having different densities and elastic coefficients, the cup body 1 having a least dense inner end 11 and a densest outer end 12, that is, the density of the cup body 1 is gradually increased from the side adjacent to the inner end 11 toward the outer end 12. In order to manufacture the cup body 1 as described above, the above-mentioned novel patent first uses a file cutter of a cotton digging machine to dig a foamed cotton block 10 having a thickness variation on the foam strip, the planing foam block 10 has a thickened end 101 adjacent the outer side and a thinned end 102 adjacent the inner side, after which the shredded foam block 10 is thermoformed. After molding, since the thickened end 101 of the planed foam block 10 is The thickness after the hot pressing changes greatly, so that it has a higher density, that is, corresponds to the outer end 12 of the cup body 1, and the thinned end 102 of the planed foam block 10 has a small change in thickness before and after hot pressing. Therefore, it has a lower density, that is, corresponds to the inner end 11 of the cup body 1.

The cup body 1 having a density change is known, although a cotton digging machine can be used to dig out the squeezing foam block 10 having a thickness variation, and then subjected to hot press forming, but is limited by the jaw cutter structure of the cotton slinger. The method can only cut out the squeezing foam block 10 which is gradually thinner or thicker in a single direction, that is, the processing method is more suitable for manufacturing the cup body 1 whose density is gradually increasing (decreasing) in a single direction. Although the conventional processing method can produce the cup body 1 having a density change, the cup body 1 whose density is gradually reduced (increased) in one direction cannot be concentrated, lifted, etc., if it is to be manufactured by the method disclosed in the aforementioned novel patent. In the case of the functional cup body 1, it is difficult to cut the squeezing foam block 10 having different thicknesses in each region by the cleavage cutter, because the cleavage cutter can only be cut out to the one side to gradually increase or become thinner. Planing the foam block 10 . Therefore, the manufacturing method disclosed in the aforementioned novel patent is not suitable for use in the production of the cup body 1 of the functional type.

It is an object of the present invention to provide a method of making a cup that is simple and quick to manufacture.

The manufacturing method of the present invention utilizes a combination of a cutting die and a hot pressing die to form a foam material into a cup body, the manufacturing method comprising: a die cutting step: using the cutting die, the foam Cut out on the material a cup substrate having a thickness variation, the cutting die including a first die holder, and a second die holder corresponding to the first die holder, the first die holder having at least one cut concave having a shallow depth a hole, and the second die holder has at least one protruding block corresponding to the cutting pocket. When the protruding block presses the foam material into the cutting pocket having a shallow change, the bubble sandwiched between the first mold base and the second mold base is cut along a cutting reference line The cotton material can cut the cup substrate having a thickness variation; and the hot press forming step: pressing the cup substrate with the hot pressing die into a cup body having different density regions.

The invention has the beneficial effects that the cup substrate can be easily cut by using the cutting recess of the cutting mold, and the cup substrate with complicated thickness variation can be easily cut. Therefore, the invention is not only innovative, but also The cup body having different densities can be produced simply and quickly.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 3, 4 and 5, an embodiment of the manufacturing method of the present invention utilizes a combination of a cutting die 2 and a hot press die 3 to produce a cup 4 having a density and thickness variation, the cup 4 comprising a cup a body 41, and a patch 42 attached to an outer surface of the cup body 41, the cup body 41 includes a low density region 411 adjacent to the bottom edge and capable of holding the breast, and a density relatively higher than the low density region a high density region 412 of 411, wherein the high density region 412 has a surrounding portion 413 surrounding the lower edge of the low density region 411, and a recess 414 above the low density region 412 by the low density The lofting, protruding and holding of the region 411 allows the breast to be displaced as far as possible to the depressed portion 414, thereby achieving the effect of supporting and concentrating the breast, and at the same time improving the wearing comfort, and the high-density region 412 can be produced. Preferred structural strength. In this embodiment, the low density region 412 can be a single density protrusion, and can also have a plurality of spaced ridges 415. The size, shape and density of the ridges 415 can be adjusted according to different functional requirements.

Referring to Figures 3, 5 and 6, in order to easily and quickly manufacture the cup 4 as shown in Figures 4 and 5, the manufacturing method of the present embodiment comprises: a laminating step, a die cutting step, and a hot press forming step. .

In the embodiment, the bonding step is to stick the patch 42 to one For the surface of the foam material 5, the bonding step may be as shown in FIG. 3, in front of the die cutting step, or between the die cutting step and the hot press forming step. And the die cutting step is to cut the foam material 5 into two cup base materials 50 having a thickness variation (only one is shown in FIG. 3) by using the cutting die 2, and the cutting die 2 includes a first die. a seat 21, and a second mold base 22 corresponding to the upper and lower sides of the first mold base 21, the first mold base 21 is substantially a rectangular body, and has a substantially horizontal surrounding plane 211, and a connecting plane 211. a middle dividing plane 212, and two cutting pockets 213 symmetrically disposed on opposite sides of the dividing plane 212, the cutting pockets 213 have a shallow and shallow variation, and the depth and depth of the region and the depth change are according to the cup 4 functions depend on it. In the present embodiment, each of the cutting pockets 213 has a deep recessed area 214 and a shallow recessed area 215, but the design of the deep recessed area 214 and the shallow recessed area 215 is not limited to one. The depth and position may be changed according to different functional requirements. For example, the depth of the deep recessed area 214 and the vicinity of the shallow concave area 215 is gradually and gently reduced.

The second mold base 22 has a substantially rectangular body 221 and two protruding blocks 222 protruding downward from the body 221. The body 221 has a first mold base 21 facing the first mold base 21 and the first mold base 22 The reference surface 220 of the seat 21 is parallel to the plane 211, and the protruding blocks 222 respectively correspond to the cutting pockets 213 of the first mold base 21, and each of the protruding blocks 222 has a separate orientation The protruding surface 223 of the recess 213, in order to cut the cup substrate 50 having a thickness variation, the bumps 222 of the embodiment have a height change, and the height of the bumps 222 is also changed according to the The function of the cup 4 depends on the function. In this embodiment, each of the protruding surfaces 223 has There is at least one first projection 224 corresponding to the deep recess 214 of the cutting pocket 213, and a second projection 225 corresponding to the dimple 215 of the recess 213, the first projection 224 The height to the reference surface 220 of the body 22 is greater than the height between the second protrusion 225 to the reference surface 220.

In other words, the present embodiment mainly utilizes the change of the depth of the cutting pockets 213 of the first mold base 21 and the height change of the protruding blocks 222 of the second mold base 22 to clamp the foam material. 5, as shown in FIG. 3, after the clamping, the protruding blocks 222 of the second die holder 22 are higher than a cutting reference line 23, and all the blades 20 are used to cut along the cutting reference line 23 horizontally. The foam material 5 is cut, so that the cup substrate 50 having a thickness variation can be quickly and easily cut. The cup substrate 50 cut through the aforementioned die cutting step has substantially a high thickness region 501 and a low thickness region 502. When cutting, since the first protrusion 224 of each of the protruding blocks 222 of the second die holder 22 corresponds to the deep recessed area 214 of each of the first die holders 21, the bubble When the cotton material 5 is interposed between the first and the second mold bases 21, 22, the portion of the foam material 5 corresponding to the deep recessed portion 214 and the first protruding portion 224 will have a relatively large thickness. This is cut below the reference line 23. By the same token, the foam material 5 corresponding to the shallow recessed area 215 of the cutting pocket 213 and the second protruding section 225 of the protruding pressing block 222 will have a smaller thickness pressed to the cutting machine alignment line. Below 23. Therefore, when the cutter 20 is cut along the cutting reference line 23, the cup substrate 50 having a thickness variation can be cut out.

In this embodiment, the hot press forming step is to hot press the cup base material 50 by using the hot press die 3, and the hot press die 3 includes two dockable And a separate hot stamping die holder 31, and a hot stamping cavity 32 which is butted by the hot stamping die holders 31. The shape, size and curvature of the hot stamping die cavity 32 are matched with the formed cup 4. In this embodiment, the thickness h1 of the low-thickness region 502 of the cup substrate 50 and the thickness h2 of the high-thickness region 501 are respectively greater than the height h3 and the height h4 of the corresponding regions on the hot-pressing cavity 32, wherein The ratio of the thickness h1 to the height h3 is greater than the ratio of the thickness h2 to the height h4.

Specifically, in the embodiment, the low-thickness region 501 of the cup substrate 50 has a thickness h1 smaller than the thickness h2 of the high-thickness region 502, but after the hot pressing, the thickness h1 is relative to the hot-pressing cavity 32. The height h3 ratio is large, so that the compaction is compacted to form a higher density, so the structural strength of the portion is better. On the contrary, although the thickness h2 of the high-thickness region 501 of the cup substrate 50 is larger than the thickness h1 of the low-thickness region 502, since the ratio of the height h4 of the hot-pressing cavity 32 to the thickness h2 is small, the region The increase in density is limited (or does not increase the density at all), so this region can produce better softness and elasticity. That is, the low-thickness region 502 of the cup substrate 50 corresponds to the high-density region 412 of the cup body 41, and the high-thickness region 501 of the cup substrate 50 corresponds to the low-density region 411 of the cup body 41.

As can be seen from the above description, the method for manufacturing the cup 4 of the present invention mainly uses the design of the cutting die 2 to form the cup base material 50 having a thickness change by die-cutting, and the cup is further formed by the hot press die 3. The substrate 50 is hot pressed to form a cup 4 having regions of different densities and thicknesses. In the die cutting step, the present invention can utilize the difference in density and thickness of different parts of the cup 4, and utilize the change of the depth of the cutting pocket 213 on the cutting die 2, and the protruding block 222 Highlight the height of the fit, easy The cup base material 50 having a thickness variation is quickly cut, and by the hot pressing of the hot press die 3, the cups 4 having different densities and thicknesses can be quickly manufactured.

Compared with the conventional steps of forming a squeezing foam block by using a cotton digger, the present invention can not only improve the cutting speed and processing convenience, but also is suitable for making cups of various functional types with density and thickness variation. Because the thickness and density of each part of the cup 4 are complicated, the present invention can complete the cutting process of the cup substrate 50 at one time by simple pressing and cutting, and during the cutting process, The shape of the cup substrate 50 is not limited by the curvature of the chopping blade at all, so the present invention is indeed an innovation, and has a manufacturing method of a cup having a simple and fast process.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
