Double-layer injection molding device for automobile interior part production

Abstract

The utility model relates to a double -layer injection molding device for car interior part production belongs to injection molding technical field, including lower mould, the upper end of lower mould swing is provided with upper mould, the inside of upper mould is provided with injection molding inner mould for injection material, to solve the problem that the single injection of present interior part injection molding mould glue can not cover big piece cavity, easy to appear dead angle position, the utility model through the replaceable setting of built -in upper die and built -in lower die, the injection molding need of different workpieces is adapted, through the cooperation of center injection pipe, feed pipe and surplus material outlet pipe, when interior part injection molding, feed pipe realizes the injection molding inside built -in lower die first, until surplus material outlet pipe flows out injection molding liquid, lower layer injection molding is completed, closes surplus material outlet pipe after completion, center injection pipe again injection molding in built -in upper die, can realize injection molding when needing single -color injection molding, directly using center injection pipe and feed pipe synchronous injection material can complete fast injection material, and the cooperation injection molding efficiency of feed pipe and center injection pipe is high, prevents dead angle.
