Description

Silicone gourd-shaped porous product mold structure

technical field

The utility model belongs to the technical field of mold forming, is an improvement on the prior art, and in particular relates to a mold structure of a gourd-shaped porous silica gel product.

technical background

The disadvantage of the current silicone gourd-shaped porous product mold is that the insertion position is set at the large end faces of the upper and lower gourds. The characteristic of the gourd-shaped porous product is that more than three gourds are stacked, and the diameters of the large ends of the upper and lower gourds are the same. If the diameter of the gourd is larger than that of the middle gourd, if the non-critical part of the middle part is not punctured, it will cause: first, when the mold is opened, the gourd-shaped inner hole of the product is easy to be broken; second, when the mold is pulled out by hand, the gourd-shaped inner hole of the product will be caused The third is unfavorable demoulding and the setting needle is easy to break. As shown in Figure 1, the front mold 1, the rear mold 2, the rear mold insert pin 3, the insertion position 4, and the fixed mold insert needle 5.

Utility model content

The purpose of this utility model is to avoid the disadvantages of the above-mentioned prior art and to provide a mold structure for a silica gel gourd-shaped porous product. The mold structure of the gourd-shaped porous product will have the characteristics that when the mold is opened, the arc-shaped inner hole of the product will not be damaged or pulled, it is beneficial to demoulding, and the insert pins are not easy to break, and the mass production of the product has been realized.

The purpose of this utility model can be achieved through the following measures:

The utility model includes a fixed mold and a movable mold, and is characterized in that a penetration structure is set at the pin-inserting position of the fixed mold and the movable mold.

The puncture structure described above includes fixed mold inserts, movable mold inserts, and puncture positions. The fixed mold inserts are set on the fixed mold, the movable mold inserts are set on the movable mold, and the fixed mold inserts and the movable mold inserts Set the penetration position at the junction of the needles.

The product appearance characteristics of the above-mentioned gourd-shaped porous product mold are equivalent to the superposition of more than three gourds, and the diameters of the large end faces of the upper and lower gourds are larger than the diameter of the middle gourd, and the puncture position is set at the non-critical size part of the middle gourd.

The mold products described above are injection molding or compression molding.

The injection molding material of the above-mentioned mold is liquid silica gel, and the material used for compression molding is solid silica gel.

Compared with the prior art, the utility model has the following advantages:

Since the utility model is an improvement on the prior art, it adopts the form of puncture in the non-critical size part in the middle, so it has the advantages of firstly, there is no strain in the mold opening, and the product quality is guaranteed; secondly, it is easy to demould and improve efficiency; thirdly, the needle is inserted It is not easy to break and saves cost. The utility model has wider practicability and can be popularized and applied.

Detailed ways

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

Referring to accompanying drawing 2, the utility model is made up of fixed mold 1, movable mold 2, puncture structure 4, fixed mold insert pin 41, movable mold insert pin 42, and puncture position 43, and is set between fixed mold 1 and movable mold 2. Break through structure 4.

The puncture structure described above includes a fixed mold insert 41, a movable mold insert 42, and a puncture position 43. The fixed mold insert 41 is set on the fixed mold 1, the movable mold insert 42 is set on the movable mold 2, and the fixed mold insert 42 is set on the fixed mold. The puncture position 43 is set at the junction of the die setting pin 41 and the movable die setting pin 42 .

The product appearance characteristics of the above-mentioned gourd-shaped porous product mold are equivalent to the superposition of more than three gourds, and the diameters of the large end faces of the upper and lower gourds are larger than the diameter of the middle gourd, and the puncture position is set at the non-critical size part of the middle gourd .

The mold products described above are injection molding or compression molding.

The injection molding material of the above-mentioned mold is liquid silica gel, and the material used for compression molding is solid silica gel.
