Abstract

The utility model discloses an anti-drawing mold entry structure of a mould. The mold has a male mold core and a female mold core of a formed product. One side of the product has a hole column. It is characterized in that the anti-drawing mold entry structure includes : the entry groove is arranged in the male mold core, and one side of the entry groove has a hanging table groove; the movable entry is movably arranged in the described entry groove, and the top of the movable entry is matched with the forming part The hole column, the bottom end of the movable inlet has a hanging platform, and the height of the hanging platform is smaller than the height of the hanging platform groove. When the mold is opened, the product relies on the sticking force to drive the movable insert to move together. Since the movable insert does not need to be separated from the product at this time, the ejection is only to overcome the gap between the product and the male mold core. The mucous membrane force between them will not cause mold drawing, and the thimble will not be white. Continue to open the mold, then the said hanger of the said movable mandrel is restricted by said said hanger groove, stops moving, and said product will continue to be pushed out, and said movable mandrel is separated from said hole post gradually.

Description

Anti-pull die entry structure of the mold

【Technical field】

The utility model relates to an anti-drawing die entry structure, in particular to an anti-drawing die entry structure of a mould. the

【Background technique】

Please refer to FIG. 1 , which is a schematic cross-sectional structure diagram of a product. As shown in the figure, the product 100 has a hole post 101 on one side. Because the hole post 101 will be bonded to the forming surface on which it is molded, and it is difficult to separate, so the forming surface of the hole post 101 cannot be set in the core of the female mold, but must be set in the core of the male mold, but the ejector pin is used to eject it. When the product is 100, it is easy to cause die drawing, and the thimble is easy to whiten. the

Please refer to FIG. 2 again. FIG. 2 is a schematic cross-sectional structure diagram of a forming mold of the product shown in FIG. 1 . The mold has a male mold core 103 and a female mold core 104 for forming the product 100, the male mold core 103 also has a peripheral part of the hole column 101 for forming the product 100, and the male mold core also has a sub-groove 102, the inlet groove 102 has an inlet 105, and the top of the inlet 105 has an inner hole part forming the hole post 101. When the product 100 is ejected, since the hole post 101 of the product 100 also has a large sticking force, the mold will be drawn during ejection, which may easily cause the ejector pin (not shown) to be white. the

In view of this, it is really necessary to provide an anti-drawing mold entry structure of the mold to solve the above-mentioned problems. the

【Content of invention】

Therefore, the purpose of this utility model is to provide a kind of anti-drawing mold entry structure of the mould, which solves the problem in the prior art that molds are used for molding products with hole columns, and the mold is easy to pull when opening the mold. the

In order to achieve the above object, the anti-drawing die entry structure of the mold of the present utility model has a male mold core and a female mold core of a formed product, and one side of the product has a hole column, and the anti-drawing die entry structure includes:

The entry slot is set in the male mold core, and one side of the entry slot has a hanging slot;

Movable inlet, movable type is arranged in the said inlet groove, the top of said movable inlet cooperates to form said hole column, said movable inlet has a hanging platform at the bottom, the height of said hanging platform is smaller than said hanging platform The height of the slot. the

Optionally, the friction coefficient between the movable inlet and the wall of the inlet groove is small. the

Compared with the prior art, the anti-drawing mold insert structure of the mold of the utility model, when the mold is opened, the product relies on the sticking force to drive the movable insert to move together, because the movable insert does not need to be connected with the active insert at this time. The products are separated, and when they are ejected, they just overcome the mucous membrane force between the product and the male die core, and will not cause mold drawing, and the thimble pin will not be white. Continue to open the mold, the hanging table of the movable entry is limited by the hanging table groove, stops moving, and the product will continue to be ejected, and the movable entry and the hole column of the product will Gradually separate. the

【Detailed ways】

Please refer to FIG. 3 . FIG. 3 is a schematic diagram of a preferred embodiment of the anti-drawing mold entry structure of the mold of the present invention. the

In order to achieve the above-mentioned purpose, the anti-drawing mold of the utility model has a sub-structure. The mold has a male mold core 201 and a female mold core 202 of a molded product 207. One side of the product 207 has a hole column 208. The anti-tension mold Entry substructures include:

The entry slot 203 is set in the male mold core 201, and one side of the entry slot 203 has a hanging table slot 204;

Movable insert 205, movable type is located in described insert groove 203, and described movable insert 205 top cooperates and forms described hole post 208, and described movable insert 205 bottom has hanging platform 206, and described hanging platform 206 The height is less than the height of the platform-hanging groove 204. the

Wherein, the friction coefficient between the movable inlet 205 and the wall of the inlet groove 203 is small, so that the mutual movement between the movable inlet 205 and the inlet groove 203 can be made smooth, avoiding hindering the Product 207. the

Please refer to FIG. 4 again. FIG. 4 is a schematic diagram of a first mold-opening state in a preferred embodiment of the anti-drawing mold entry structure of the mold of the present invention. the

When opening the mold, the product 207 relies on the sticking force to drive the movable insert 205 to move together. Since the movable insert 205 does not need to be separated from the product 207 at this time, it is only necessary to overcome the contact between the product 207 and the product 207 during ejection. The mucous membrane force between the male die cores 201 will not cause mold drawing, and the thimble (not shown in the figure) will not be white. the

Please refer to FIG. 5 . FIG. 5 is a schematic diagram of a second mold-opening state of a preferred embodiment of the anti-drawing mold entry structure of the mold of the present invention. the

Continue to open the mold, then the hanging table 206 of the movable entry 205 is limited by the hanging table groove 204, stops moving, and the product 207 will continue to be ejected, and the movable entry 205 and the product will The holes 208 of 207 gradually separate. the
