Abstract
The invention discloses an injection molding method of a double-color super-thick cladding element. A CAE analysis technique of Moldflow is adopted for layering design for the wall thickness of the double-color super-thick cladding element; injection molding is carried out twice in two molds; the injection molding is carried out under a high-temperature high-pressure low-speed condition and the relatively high mold temperature and the external condition of secondary molding are controlled so as to obtain a final product. The injection molding method has the advantages that the double-color super-thick cladding element can be prepared; meanwhile, the internal air bubbles of a product can be prevented; the flow mark on the surface of the product is eliminated; the appearance quality of the product is ensured.
Description
Technical field
The present invention relates to plastics injection mould, specifically a kind of double-colored super thick coating member injection molding forming method.
Background technology
The many merits such as double-shot moulding product is attractive in appearance, practical with it, good hand touch, have been widely accepted practicality, as toothbrush, phone housing, automobile tail light etc.Double-colored super thick coating member skin is transparent, and internal layer is color plastic materials and parts, and this plastic internal layer is easy to change color and need not spray, and product appearance can be made more beautiful.But heavy wall Injection moulded part very easily produces the defects such as shrinkage cavity, pit, bubble, weld mark, and do not allow to occur this defect in double-colored transparent plastic part, this product structure to the injection mo(u)lding of double-colored super thick coating member, mould structure and Shooting Technique are had higher requirement.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of injection molding forming method of double-colored super thick coating member is provided, meanwhile, eliminate the defects such as shrinkage cavity, bubble, weld mark, ensure product appearance quality.
