Abstract

The invention provides an automatic ejection device with a delay function and a mold having the same, comprising a base, an upper cover, a pressing block, a dial, a locking block and an ejecting piece, the upper cover is fixedly arranged on the base, and the base is arranged There is a placement slot, the dial block is set in the placement groove, the upper cover is provided with a press block installation hole, the dial block is provided with a press block guide hole and a lock block guide hole, the lower end of the press block is arranged through the press block guide hole, and the upper end of the press block is provided with The installation hole of the pressure block is arranged, the lock block is arranged in the guide hole of the lock block, the guide hole of the pressure block and the guide hole of the lock block are communicated with each other, the lock block is arranged in contact with the pressure block, and one end of the ejection piece is installed on the dial block, and also It includes an elastic piece, the elastic piece is arranged in the guide hole of the lock block, one end of the elastic piece is arranged in the dial block, and the other end of the elastic piece is connected with the lock block. It can reduce the overall size of the mold, remove the ejector plate, oil cylinder, push plate and other devices that rely on external force to release the mold, reduce production costs, shorten research and processing time, easy assembly and replacement, and no hidden danger of mold collision.

Description

technical field [0001] The invention relates to the technical field of injection moulds, in particular to an automatic ejection device with a delay function and a mould having the same. Background technique [0002] Plastic products generally complete their molding process by injection molds. The manufacturing process is generally to first inject the melt into the cavity of the injection mold, then cool and form, and then open the mold to eject the product from the injection mold by the ejection structure in the mold, so that the product is completely demolded. In the process of product ejection, it is necessary to protect the integrity of the product as much as possible so that it has a better molding effect. [0003] Most of the existing ejector devices use air cylinders or oil cylinders to drive the ejector plate or the pusher to move up and down, and the ejector plate then drives the pusher or the pusher to move up and down through the push rod. , and then the dial blo...
