Description

Fixed structure of plastic machine mold

The utility model relates to a fixing structure of a plastic mould.

Usually, to manufacture a product, several machine tools and tools must be used. The processing method of mass production in modern industry promotes the manufacture of products, which not only saves time and labor, but also meets the requirements of product interchangeability. Therefore, in the manufacturing process of precision products, high processing accuracy and fast loading and unloading are required. The fixture is used to help production, so that the workpiece can be correctly positioned and fixed in the proper position during the processing, so as to facilitate processing. In the fixture structure of a common plastic machine (see Figure 5), one side of the fixed splint 2 rests on the flange derived from the lower die 1, and an iron block 3 is placed under the other side. The height of the iron block 3 is equal to the height of the lower die 1. The height of the edge 11 is then passed through the groove 21 of the clamping plate 2 with a screw 4, and screwed with the screw hole on the lower mold fixing plate 9, thereby fixing the lower mold 1.

Because the thickness of general lower die 1 flange 11 is divided into five standard sizes such as 1/2 inch, 5/8 inch, 3/4 inch, 7/8 inch and 1 inch, so the fixing splint 2 also needs five pieces of different sizes. The iron block 3 cooperates for the fixing of the lower die 1, and its assembly is troublesome, resulting in inconvenient production and increased manufacturing cost; while the screw 4 passes through the groove 21 of the fixing splint 2, and is bolted in the screw hole of the lower die fixing plate 9 , the screw 4 is not easy to fasten, and often slides in the groove 21, and the iron block 3 will also loosen or fall off, thereby affecting the fixing effect; and because the screw 4 is in direct contact with the fixing splint 2, it is easy to cause the surface of the fixing splint 2 to wear, It will also affect the firmness of the fixed splint.

The purpose of the utility model is to provide a fixing structure for plastic machine moulds, which is easy to assemble, has good fixing effect, convenient production operation and low manufacturing cost.

In order to achieve the above object, the utility model is mainly composed of splints, screws, positioning blocks, washers, nuts and bolts and other components. Among them: the splint is a long block with a screw hole on the right side of the block for the screw body to screw in and adjust the positioning according to the height of the flange of the lower die; the left side of the block is cut inward to set a long A chute is used to insert and pull the bolts, and the length of the bolts is determined according to the needs of the work; some suction flowers are carved under the left edge of the block to increase the clamping force of the splint when in use. The screw is divided into a screw head and a screw body. The positioning block is a block in the shape of a door, which can be sleeved on the splint, and a round hole is dug corresponding to the relevant position of the chute on the splint. The washer is placed between the nut 82 and the positioning block 8 . Bolt 7 is a long rod body, which is bolt A, bolt B, bolt column and bolt C from top to bottom. The diameter of the bolt column is larger than bolt C. The studs are against the surface of the lower die fixing plate to protect the bolts from deformation of the thread on the lower die fixing plate and the screw holes of the lower die fixing plate due to the torsional moment when they are over tightened. The nut is screwed onto the bolt A.

When assembling, turn the screw body of the screw upside down and screw it into the screw hole of the splint, place the bolt B of the bolt in the chute, and screw the bolt C into the screw hole of the lower mold fixing plate, and the end edge of the splint The suction flower is just on the flange of the lower die. Screw out the screw downwards, and after adjusting to the height equal to the flange of the lower mold, the positioning block can be placed on the splint, and the bolt A is protruded from the round hole 81 of the positioning block, and then the washer is put on the screw. When the nut is inserted, the positioning block presses the splint so that it and the lower mold fixing plate are in a fastened state.

After adopting the above structure, the utility model only needs one set of components to adapt to templates of different thicknesses, which is convenient to assemble and low in cost; and its bolt is composed of four parts, and the diameter of the stud is larger than the bolt C, so that the bolt can be fastened It will not be deformed by the torsion force; and the positioning block and the washer are placed under the nut, so that the fixing effect is better.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Please refer to Fig. 1, Fig. 4, the utility model is mainly made up of components such as splint 5, screw 6, positioning block 8, washer 83, nut 82 and bolt 7. Wherein: splint 5 is an elongated block body, runs through a screw hole 52 on the right side block body, adjusts positioning for screw 6 screwing in; Insert the bolt 7, and determine the length of the bolt according to the needs of the work; under the left end edge of the splint 5, carve some suction flowers 53, which can increase the clamping force of the splint 5 when in use. The screw 6 is divided into a screw head 61 and a screw body 62, and the screw thread on the screw body 62 is used to screw into the right screw hole 52 of the splint 5, and the positioning is adjusted by the height of the flange 11 of the lower mold 1. The positioning block 8 is a door-shaped block, which can be sleeved on the clamping plate 5, and a circular hole 81 is dug corresponding to the relevant position of the chute 51 on the clamping plate 5. The washer 83 can be placed between the nut 82 and the positioning block 8 . The nut 82 can be screwed onto the bolt 71 of the bolt 7 . Bolt 7 is a long rod body, which is divided into bolt 71, bolt 72, bolt 73 and bolt 74 from top to bottom. The diameter of bolt 73 is larger than bolt 74. The stud 73 on it is against the surface of the lower mold fixed plate 9, so as to prevent the deformation of the thread on the screw hole of the lower mold fixed plate 9 and the bolt 74 by the action of torque when the bolt 7 is not too fastened.

When assembling (please refer to Fig. 2), screw the screw body 62 of the screw 6 upside down and screw it into the screw hole 52 of the splint 5, make the bolt 72 of the bolt 7 accommodate in the chute 51, and screw the bolt 74 into the lower mold In the screw hole of the fixing plate 9, and the suction flowers 53 on the end edge of the clamping plate 5 are just against the flange 11 of the lower mold 1.

Screw the screw 6 downwards and adjust it to the same height as the flange 11 of the lower mold 1 (as shown in Figures 3A-3E), then the positioning block 8 can be placed on the splint 5, and the bolt 71 can be pushed by the positioning block 8 The circular hole 81 is stretched out, and then the washer 83 is put on, and the nut 82 is screwed in, so that the positioning block 8 presses the splint 5, so that it and the lower die fixing plate 9 are in a fastened state, as shown in Figure 4 .

In this way, a jig with high processing accuracy and quick assembly and detachment is formed, and its manufacturing cost is low.
