Workpiece double-color forming mold

Abstract

The invention relates to a workpiece double-color forming mold. The workpiece double-color forming mold comprises a hard mold and a soft mold which are arranged in parallel. The hard mold comprises a hard mold body and a first manipulator, and both the hard mold body and the first manipulator are provided with a plurality of groove bodies. When the hard mold body and the first manipulator are combined, the groove bodies of the hard mold body and the groove bodies of the first manipulator are oppositely sealed and jointly form a plurality of chambers of workpiece hard body structures. The soft mold comprises a soft mold body and a second manipulator, and both the soft mold body and the second manipulator are provided with a plurality of groove bodies. When the soft mold body and the second manipulator are combined, the groove bodies of the soft mold body and the groove bodies of the second manipulator are oppositely sealed and jointly form a plurality of chambers of workpiece body structures. Each workpiece body is composed of a workpiece hard body and a workpiece soft body in a combined mode. The hard mold body and the first manipulator serve as one mold, the soft mold body and the second manipulator serve as one mold, in this way, the dual-purpose functions of the manipulators are achieved, the manipulators can transfer injection molding products and can also be used as the molds, and mold rotating operation is avoided.

Description

technical field [0001] The invention relates to a molding device, in particular to a two-color molding die for a workpiece. Background technique [0002] The structure of injection molding products in the prior art is becoming more and more diverse. For example, the structure of a toothbrush handle usually includes a handle with a relatively hard material, and at the same time includes a grip or decoration wrapped on the outer surface of the handle with a softer material. Department, which involves the issue of secondary injection molding. In the prior art, secondary injection molding needs to rotate and exchange the inner cores of the hard mold and the soft mold, and the addition of a rotating structure in the two molds will make the mold structure more complicated. The processing of some specific injection molding products is limited, and the rotating structure restricts the processing diversity performance of the mold.
