AI Technical Summary
Technical Problem
In existing technologies, when the same product is made of multiple materials, multiple sets of injection molds are required, resulting in high production costs and low production efficiency.
Method used
Using a four-color injection mold, multiple injection cavities are set on the same mold for different parts, including injection cavities for forming the inner shell, lower shell and upper shell of the injection molded part. Combined with a specific injection channel and inlet design, it can realize the splicing of multiple materials.
Benefits of technology
By producing different parts of an injection molded part on the same mold, production costs are reduced, production efficiency is improved, and the accurate and rapid movement of semi-finished products is ensured.

Abstract
本发明公开了四色注塑模具，包括上模组件和下模组件，上模组件和下模组件配合形成第一注塑腔、第二注塑腔和第三注塑腔，第一注塑腔注塑形成注塑件内壳，第二注塑腔注塑形成注塑件外壳下部，第三注塑腔注塑形成注塑件外壳上部。该四色注塑模具通过设置注塑形成注塑件不同部分的第一注塑腔、第二注塑腔和第三注塑腔，从而实现在同一模具上注塑完成注塑件的不同部分，且由于注塑过程中形成的半成品由同一模具的一注塑腔移入另一注塑腔，移动准确、快捷。综上可知，该四色注塑模具有效降低生产成本，提高生产效率。相应地，公开了基于四色注塑模具的注塑件分区注塑方法。
