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. The product is manufactured by a molding device. Regarding the problems that the plastic product is a tube product, core loosing is firstly carried outon the front mold side before a gap is formed in the middle, the middle of the tube is hollow, it is difficult to demold, and demolding easily causes large product deformation, so that the product isscrapped, a corresponding demolding mechanism and a device mechanism are designed, the device mechanism comprises a mold base mechanism component, a molding part assembly component, a left side bentpin core loosing assembly component and a right long core loosing assembly component, and the molding device has the advantages that the structure is simple in design, automatic molding is achieved onfeature positions on which demolding cannot be performed, the structure design is simple, the reliability is high, and the mold manufacture cost is low.
