| description | The invention discloses an injection molding method for forming a double-color product with an upper cover, which comprises the following steps: S1, filling a transparent mold cavity with two high-molecular polymer viscous-state mixtures with different colors, the two high-molecular polymers with different colors respectively being a high-molecular polymer with phototaxis and a high-molecular polymer without phototaxis; and S2, a light source is turned on above or below a transparent mold cavity, and the viscous-state mixture is separated through the phototaxis of the high-molecular polymer materials with the two different colors. According to the technical scheme provided by the invention, one-step molding can be carried out according to different phototaxis properties of two materials, so that the production of a double-color injection molding product is realized; the mold is relatively simple to manufacture, two sets of molds with different cavities are not required to be manufactured for double-color inje |
