Embodiment Construction

[0023] The technical solution provided by the present invention is: melting two plastic materials of different colors to form a viscous fluid mixture, using the different material properties of the two plastic materials to make the two plastic molecules in the viscous fluid mixture form different movements Direction, so that the two plastic materials mixed in the viscous flow state are separated, and the plastic material molecules of different colors are gathered together, and the two-color injection molding is completed through one molding.

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Abstract

The invention is applicable to the technical field of plastic injection and provides a double-color plastic injection method, which comprises: a, filling a viscous flow state mixture of two plastic materials of different colors in a molding cavity of a mold; and b, separating the viscous flow state mixture according to the material properties of the two plastic materials of different colors, wherein the plastic material of one color moves to gather on a dynamic mold side and the plastic material of the other color moves to gather on a fixed mold side. According to the technical scheme provided by the invention, double-color plastic injection products can be produced by one-step forming, and the mold manufacturing is relatively simple as a single mold instead of two molds of different molding cavities is manufactured for double-color plastic injection. The technical scheme provided by the invention is more applicable to appearance pieces with complex structures.

Description

technical field [0001] The invention belongs to the technical field of injection molding, and in particular relates to a two-color injection molding method. Background technique [0002] The current two-color molding technology, whether it is insert molding or molding by a two-color molding machine, can only achieve the two-color effect through two injection moldings. [0003] In the prior art, in addition to completing the two-color injection molding through a two-color molding machine, there are other methods to make a simulated two-color molding effect. Such as figure 1 As shown, first make a transparent product in the cavity 102, and then spray another color of paint on the moving mold side of the product. From the front view, the effect of imitating two-color molding can also be achieved by using the optical reflection effect. . However, this method has high requirements on mold processing and assembly, and sometimes there are inevitably some defects such as insert l...
