Background

Injection molding is a method for producing shapes of industrial products, and rubber injection molding and plastic injection molding are generally used for products, and injection molding can be divided into an injection molding compression molding method and a die casting method. In the injection molding process, an injection mold is a critical device, and an important component, namely an inclined pin, is included in the injection mold, wherein the inclined pin is commonly arranged on the male mold side of the plastic mold, and has two functions, namely, one of the inclined pins is provided with a reverse hook at the molding part, and a common sliding block and an insert cannot meet the requirement. Secondly, the inclined pin participates in the molding in the time of demolding, die assembly, pressure maintaining and accommodation molding. However, when the molding is finished and the mold is opened, the inclined pin can be demolded along with the set angle along with the movement of the mold plate, so that the molded part is ensured not to be pulled up, and the ejection of the accommodation product is participated. Before use, the taper pin needs to be installed at a designated position of the male die by using clamping equipment, but the surface of the taper pin is an arc surface, so that the taper pin is easy to slide off during clamping, and the normal assembly of the die is not easy.
