At present, due to the advantages of good quality and low cost of the products formed by the forming die, the forming die is widely used in various industries.

Among them, in the structural design of plastic products, in order to meet different process requirements, side holes, side grooves or side blind holes are often opened around the product. Therefore, for molding with side holes, side grooves or side blind holes Correspondingly, a side core-pulling mechanism will be provided on the forming mold. Through the side core-pulling mechanism, the forming mold will be side-cored and then demolded during the mold opening process, thereby ensuring the mold release of the forming mold. went well.

At present, the existing forming molds include a male mold, a female mold, a side core pulling mechanism and an ejection mechanism. The male mold and the female mold cooperate to form a molding cavity; the side core pulling mechanism includes an inclined guide column and a side slider. Inside, one end of the inclined guide post is installed obliquely on the female mold, and the other end of the inclined guide post extends into the side slider, and the ejector mechanism is built in the male die and ejects the product formed in the molding cavity.

However, since the side slider and the ejector mechanism are both arranged on the male mold, there will be a problem of mutual interference between the side slider and the ejector mechanism arranged on the male mold. On the one hand, it is not convenient for core pulling and assembly, and on the other hand, the development costs.
