Description

Slider structure with multi-angle side draw

【Technical field】

The invention relates to a slider structure, in particular to a slider structure with multi-angle side draw.

【Background technique】

Please refer to FIG. 1 , which is a schematic structural diagram of a product. There are several undercuts 101 around the product 100, and the directions of each undercut 101 are different (here, each undercut 101 is evenly distributed on a circle).

Please refer to FIG. 2 . FIG. 2 is a schematic structural diagram of a slider for multi-angle side extraction in the prior art. For the production of this type of product 100, the slider structure shown in Figure 2 is usually used at present, and the structure includes several slider bodies 103 (corresponding to the number of undercuts 101), and each slider body 103 corresponds to An undercut insert 104, through each of the undercut inserts 104, the undercut 101 at each angle is formed, and then the side pull is performed through the shift block 105 inserted in each of the slider bodies 103, The side of the slider body 103 away from the undercut 104 usually has a bundle block 106 , and the bundle block 106 limits the position of the slider body 103 .

However, with the above-mentioned slider structure, since the exit direction of each undercut 101 is different, each undercut 104 must be driven by a separate design of the slider body 103, resulting in many mold parts and a large mold space. , which in turn leads to the problem of large mold size and complicated installation.

In view of this, it is necessary to develop a large-angle oblique pin structure of the mold to solve the above-mentioned problems.

【Content of invention】

Therefore, the purpose of the present invention is to provide a multi-angle side-drawing slider structure to solve the problem that there are undercuts around the product. The slider structure used requires many mold parts, takes up a large mold space, has a large mold size, and is difficult to install. complicated question.

In order to achieve the above purpose, the present invention provides a multi-angle side-drawing slider structure. The slider structure is formed with products with undercuts in different directions around it. The slider structure includes:

The male mold core is provided with several limiting grooves pointing to its center, and the center position of the male mold core forms the product;

A plurality of slider inserts are arranged in the limiting grooves one by one, and the slider inserts form the undercuts one by one, and guide pins are provided on the slider inserts;

The slider body, which fits above the slider insert, the slider body is a ring structure, and several guide grooves are opened below the slider body, and the guide grooves are provided with the corresponding guide grooves one by one. A guide pin, one side of the slider body has a dial pin;

The shifting block is fixed on the mother mold, and there is a chute below the shifting block, and the dial pin is movable in the chute.

Optionally, the slider body has a groove, and the slider structure further includes a pressing block, one end of the pressing block is fixed on the male template, and the other end is pressed into the groove.

Optionally, a positioning groove is provided under the slider body, and a pinball structure is provided on the male core, and the pinball structure has a spring to be supported and a positioning steel ball arranged above the spring.

Optionally, the male mold core has a screw hole, and a screw is arranged in the screw hole, and one end of the screw has the positioning hole, and the spring is arranged in the positioning hole, and a screw is arranged above the spring. The positioning steel ball falls into the positioning groove in the mold opening state.

When the mold is opened, the shift block fixed on the female mold core drives the dial pin to rotate, thereby achieving the rotation of the slider body, the guide groove on the slider body and the male mold core. The limit slots work together to achieve the side-drawing of each of the slider inserts and the undercut of the product.

It can be seen that compared with the prior art, the multi-angle side-drawing slider structure of the present invention can solve the withdrawal of products with undercuts all around. Since only one slider body is used, fewer mold parts are required and mold space is occupied Small size, small mold size, and easier installation.

【detailed description】

Please refer to Fig. 3, Fig. 5, and Fig. 6 together. Fig. 3 is a schematic diagram of a preferred embodiment of the multi-angle side-drawing slider structure of the present invention. A preferred embodiment of the slider structure of the side drawer is an exploded schematic view from the first viewing angle, and FIG. 6 is an exploded schematic view from the second viewing angle of a preferred embodiment of the slider structure of the multi-angle side drawer of the present invention.

In order to achieve the above purpose, the present invention provides a multi-angle side-drawing slider structure. The slider structure is formed into a product 100 with undercuts 101 in different directions around it (please refer to Figure 1 again). The slider structure includes:

The male mold core 200 is provided with several limiting grooves 201 pointing to its center, and the center position of the male mold core 200 forms the product 100;

A plurality of slider inserts 300 are arranged one by one in the limiting groove 201, and the slider inserts 300 form the undercuts 100 one by one. The slider inserts 300 have guides. pin 301;

Slider body 400, which fits above the slider insert 300, the slider body 400 is a ring structure, and several guide grooves 401 are opened below the slider body 400, and a guide groove 401 inside the guide groove 401 One correspondingly has the guide pin 301, and one side of the slider body 400 has a dial pin 402;

The shifting block 500 is fixed on the core of the female mold (not shown in the figure), and the bottom of the shifting block 500 has a chute 501, and the dial pin 402 is movable in the chute 501.

In this embodiment, the slider body 400 has a groove 403, and the slider structure also includes a pressing block 600. One end of the pressing block 600 is fixed on the male template (not shown in the figure), and the other end is pressed on the on the groove 403 . Through the pressing of the pressing block 600 , the slider body 400 will not move relative to the male mold core 200 in the vertical direction.

In this embodiment, the slider body 400 has a positioning groove 404 under it, and the male mold core 200 has a pinball structure. The positioning steel ball 204 is in the mold opening state, and the positioning steel ball 204 falls into the positioning groove 404 . The positioning steel ball 204 plays a positioning role to ensure that the shift pin 401 can be smoothly inserted into the chute 501 of the shift block 500 when the mold is closed. Specifically, there is a screw hole 202 on the male mold core 200 here, and a screw 205 is arranged in the screw hole 202, and the positioning hole 206 is arranged at one end of the screw 205, and the positioning hole 206 is provided with the The spring 203, the positioning steel ball 204 is arranged above the spring 203. The positioning hole 206 is provided in the screw 205 to accommodate the spring 203, which can facilitate the replacement of the spring 203 after aging.

Please refer to Fig. 4 and Fig. 7 again. Fig. 4 is a schematic diagram of a preferred embodiment of the slider structure of the multi-angle side drawer of the present invention in the mold opening state, and Fig. 7 is a schematic view of the multi-angle side drawer of the present invention. Partial cross-sectional view of the mold opening state of a preferred embodiment of the slider structure.

When opening the mold, the shifting block 500 fixed on the female mold core drives the shifting pin 402 to rotate, thereby achieving the rotation of the slider body 400, the guide groove 401 on the slider body 400 and the The limiting slots 201 on the male mold core 200 work together to achieve the side extraction of each of the slider inserts 300 and break away from the undercut 101 of the product 100 .

When closing the mold, the dial pin 401 is inserted into the chute 501 of the dial 500, and the dial 500 drives the slider body 400 to rotate, and finally drives the slider inserts 300 to reset.

It can be seen that by utilizing the multi-angle side-drawing slider structure of the present invention, the withdrawal of the product 100 with undercuts 101 all around can be solved. Since only one slider body 400 is used, the required mold parts are few, the mold space is small, and the mold space is small. Small size and easier installation.
