Abstract

The invention discloses a bicolor mold, which comprises an upper mold plate (1), a lower mold plate (2), a sliding block (3) and a mold mount (4), wherein the lower mold plate (2) is fixed on the mold mount (4); the upper mold plate (1) is arranged above the lower mold plate (2); a front mold push plate (5) is arranged between the upper mold plate (1) and the lower mold plate (2); the sliding block (3) is arranged on the front mold push plate (5); during demolding, the front mold push plate (5) and the upper mold plate (1) together are disconnected together with the lower mold plate (2) and the front mold push plate (5) is separated with the upper mold plate (2); a turntable is fixed on the lower surface of the mold mount (4); a guide column hole (6) is formed in the sliding block (3); a guide column (7) in sliding match with the guide column hole (6) is arranged on the upper mold plate (1). According to the bicolor mold, the cost is greatly reduced as the precision requirement of mold processing is low.

Description

technical field [0001] The invention relates to an injection mold, in particular to a two-color mold. Background technique [0002] Most of the plastic products are formed by injection molds. With the help of injection molds, plastic products with the desired shape can be efficiently molded, thus accelerating the development of injection molds. Two-color injection refers to the combination of two different colors or different types of plastics. The process of making finished products with different colors or different appearance hardness through injection molding process. [0003] According to the existing technology, when molding plastic products with two colors or more than two colors, especially for products with secondary injection products in both cavities and cores, and products with plastic coating on both sides, the mold The slider and the front mold need to be replaced, and a rotary shaft injection molding machine is required to complete the injection molding. Howe...
