Problems solved by technology

Although the existing injection mold improves the precision of the injection molded workpiece, after the product is cooled and formed, because the mold cavity needs to maintain high pressure during the molding process, the upper and lower molds are pressed tightly under the action of high pressure, so it is not easy to come off. mold, it is easy to cause the finished product to be scrapped, reduce the rate of finished product, increase the labor intensity, reduce the production efficiency, and is not suitable for mass production and manufacturing

Abstract

The invention relates to a shoe-making mold, and discloses a mold device easy to demold. The mold device has a simple structure and is quickly demolded, and yield and production efficiency of injection molding is effectively improved, and the mold device is suitable for mass production and use. a telescopic cavity is arranged on an upper die core positioned above an upper mold cavity of the mold device; a brake rod is arranged on a shoe tree and can move up and down and penetrate into the telescopic cavity; a brake plate is fixedly connected to the end of the brake rod in the telescopic cavity; a telescopic base is arranged on the upper mold base, a telescopic rod capable of moving up and down penetrates through the telescopic base, and one end of the telescopic rod penetrates into the telescopic cavity and is connected with the brake plate; a pressurizing device is also arranged on the upper mold base, and a pressurizing end of the pressurizing device communicates with the telescopiccavity; and an exhaust valve is also arranged on the telescopic cavity.

Description

technical field [0001] The invention relates to the technical field of shoemaking moulds, in particular to an easy-demoulding mold device. Background technique [0002] The injection molding method of existing shoes is to carry out injection molding of thermoplastic materials such as PVC or TPR through the injection molding mold of the injection molding machine, including mold closing, glue injection, pressure maintaining, cooling, demoulding, and product taking out, specifically refers to heating and melting The material is injected into the mold cavity, cooled and solidified, and then the mold is opened to take out the molded product. [0003] The current injection mold usually includes an upper mold and a lower mold. The upper mold includes an upper mold seat and an upper mold core, and the lower mold includes a lower mold seat and a lower mold core. The upper mold core and the lower mold core are generally respectively fixed on the upper mold by fasteners. On the seat a...
