Pressure injection mold for shock pad

Abstract

The invention discloses a pressure injection mold for a shock pad. The pressure injection mold comprises a mold body and a heating and pressurization mechanism. The mold body comprises a glue pressing plate, an upper template and a lower template. The lower template is provided with a plurality of evenly-distributed part grooves. Each part groove is provided with a corresponding glue injection part. The heating and pressurization mechanism comprises a heater and a pull-push air cylinder. The pressure injection mold for the shock pad is provided with the multiple part grooves, the multiple part grooves can be subjected to hot melting at a time, production efficiency is improved, the upper template and the lower template are positioned through positioning pins, the mold is more accurate, automatic burr removal can be achieved, accordingly, the follow-up working procedure that burrs are removed manually or removed through other devices is omitted, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for shock absorbing pads of automobiles. Background technique [0002] The injection molding mold is to inject the preheated rubber into a plastic state through the gating system of the injection mold into the mold for finalization and vulcanization. It is suitable for the manufacture of large, thick-walled, thin-walled, and complex-shaped rubber products. The hot-melt fixture can only melt one product at a time, and there is no pre-pressing action. Not only the production efficiency is poor, but the quality of the hot-melt product is also poor. At the same time, the rubber material is put into the mold, and the mold is opened after molding. The edge of the product is pasted with waste material, and the material around the product needs to be removed. In the prior art, manual trimming or hand tearing is generally used to remove the burrs, which consumes...

AI Technical Summary

Problems solved by technology

The lower template in the pouring mold provided by the above invention is provided with an auxiliary molding assembly, and two cylinder molding cavities are formed between the auxiliary molding in the auxiliary molding assembly, the upper molding, and the lower molding, so that one mold with two molds can be realized. hole, improve the yield, but did not effectively remove the burr, consume a lot of human resources, and also lengthen the processing flow of rubber products
