Abstract

The invention provides an automatic ejection device with a time delay function and a mold with the same. The automatic ejection device comprises a base, an upper cover, a pressing block, a shifting block, a locking block and an ejection part, wherein the upper cover is fixedly arranged on the base, a positioning groove is formed in the base, and the shifting block is arranged in the positioning groove. A pressing block mounting hole is formed in the upper cover, and a pressing block guide hole and a locking block guide hole are formed in the shifting block. The lower end of the pressing blockpenetrates through the pressing block guide hole, the upper end of the pressing block penetrates through the pressing block mounting hole, and the locking block is arranged in the locking block guidehole. The pressing block guide hole and the locking block guide hole communicate with each other, the locking block is in contact with the pressing block, and one end of the ejection part is arrangedon the shifting block. An elastic part is further included, and the elastic part is arranged in the locking block guide hole. One end of the elastic part is arranged in the shifting block, and the other end of the elastic part is connected with the locking block. The overall size of the mold can be reduced, devices, demoulded by external force, such as an ejector pin plate, an oil cylinder and a push plate can be removed, the production cost is reduced, the grinding and processing time is shortened, the assembling and replacing are convenient, and the hidden danger of mold collision is avoided.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an automatic ejection device with a delay function and a mold with the same. Background technique [0002] Plastic products are generally formed 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 through the ejection structure in the mold, so that the product is completely demoulded. 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 ejection devices use a cylinder or an oil cylinder to drive the ejector plate or the pusher to move up and down, and the ejector plate drives the pusher or the pusher to move up and down through the push rod. The pusher or the pusher drives the shifting bl...
