Description

Inner drawing inclined pin die structure Technical Field The invention relates to the technical field of dies, in particular to an inner-drawing inclined pin die structure. Background At present, injection molding is also called injection molding, which is a molding method of injection and molding. The injection molding method has the advantages of high production speed, high efficiency, automation in operation, multiple patterns, various shapes, large size, accurate product size, easy updating of the product, and capability of forming parts with complex shapes, and is suitable for the field of mass production, products with complex shapes and other molding processing. When the back-off in the normal product is more, the angle pin is required to withdraw from the back-off, but the angle pin and the thimble in the common angle pin mode are ejected together, and the product and the angle pin can be pulled to walk together, so that the product is not taken out well. Disclosure of Invention The invention aims to provide an inner-drawing taper pin die structure, which solves the problem that products are not taken out well. The invention provides a technical scheme that the inner inclined pin die structure comprises a female die plate and a male die plate, wherein a hot runner plate, an upper fixing plate and a heat insulation plate are fixed on the top of the female die plate sequentially through hexagon bolts, a female die core and a male die core are respectively and fixedly arranged on the bottom of the female die plate and the top of the male die plate, two die legs are fixedly arranged on the bottom of the male die core, a lower fixing plate is fixedly arranged on the bottoms of the two die legs together through screws, a panel is slidably arranged between the two die legs, a thimble is fixedly arranged on the top of the panel, the bottom of the panel is connected with a bottom plate through countersunk screws, a cavity is formed between the female die core and the male die core in a relative mode, and inclined pins are arranged in the cavity, and the inner inclined pin die structure further comprises: a carrier plate slidably mounted between the male mold plate and the mold base; The inclined pin shovel machine is fixedly arranged at the top of the bearing plate and is used for pulling the inclined pin to horizontally move and withdraw from the back-off; the shutters are arranged between the female template and the male template and are used for locking or loosening the male template and the female template; The equal-height screws are positioned between the male template and the bearing plate and used for limiting the bearing plate, and the bearing plate is slidably assembled outside the equal-height screws. Preferably, a button machine main part is arranged on one side of the male template, a button machine shifting block and a button machine ejector rod are respectively arranged on the button machine main part, and the button machine shifting block and the button machine ejector rod respectively compress and fix the male template and the panel. Preferably, the plurality of shutters are fixedly installed at the bottom of the master template. Preferably, the equal-height screws are in threaded connection with the male template, the support plate is provided with a plurality of guide holes, the equal-height screws are partially nested in the corresponding guide holes, and the top ends of the equal-height screws are provided with limiting parts of an integrated structure. Compared with the prior art, the invention has the following beneficial effects: according to the invention, through the arrangement of the structures such as the bearing plate and the taper pin, the bearing plate firstly moves to drive the taper pin to withdraw from the back-off, a product is left on the male die core and cannot move along with the taper pin, after one end of the product moves for a distance, the bearing plate stops moving under the action of the equal-height screw, then the male die plate and the female die plate are subjected to die sinking by the main fastener and the pulling block of the fastener, and then the product is ejected out, so that the taper pin and the ejector pin are separated to move, the product is conveniently taken out, and the product cannot be damaged by the taper pin.
