Problems solved by technology

[0002] When plastic products are molded by injection molding process, the demoulding of the product is a difficult problem and the key point in production. For complex products, the key point of the structural design of the forming mold is the design of the demoulding mechanism and the layout of the overall structure of the mold. Sometimes, the product The complexity of the structure makes the product unable to come out after injection molding, making the injection molding of the product an impossible process plan. For example, the product used by this device has a hollow tube in the middle, and the front mold barb is designed in the middle part. It is very difficult to demould, and it is necessary to design an ingenious demoulding mechanism and mold device structure to achieve the purpose of automatic production

Abstract

The invention provides a porous plastic product forming device. Aiming at the problems that a plastic product is a piping outfitting product, a notch is formed in the middle, a front mould side needsto be core-pulled firstly, the middle of a pipe is hollow, the difficulty in demoulding is caused, and the product is easy to deform so as to be scrapped due to demoulding, a corresponding demouldingmechanism and a device structure are designed. The device structure comprises a mould base mechanism part, a molding part assembly part, a left-side dog-led cam core slide assembly part and a right-side long-core pulling assembly part. The porous plastic product forming device achieves the beneficial effects of simple structure design, capability of automatically demoulding the feature positions incapable of being demoulded, simple mechanism design, high reliability, and low mould manufacturing cost.

Description

technical field [0001] The invention relates to the field of structural design of injection molds, in particular to a molding device for porous plastic products and a method for using the same. Background technique [0002] When plastic products are molded by injection molding process, the demoulding of the product is a difficult problem and the key point in production. For complex products, the key point of the structural design of the forming mold is the design of the demoulding mechanism and the layout of the overall structure of the mold. Sometimes, the product The complexity of the structure makes the product unable to come out after injection molding, making the injection molding of the product an impossible process plan. For example, the product used by this device has a hollow tube in the middle, and the front mold barb is designed in the middle part. Demoulding is very difficult, and it is necessary to design an ingenious demoulding mechanism and mold device structu...
