Problems solved by technology

[0002] Two-color mold is a mold in which two plastic materials are injected on the same injection molding machine and molded twice, but the product is only molded once.
Two-color molds are becoming more and more popular in the market. This process can make the appearance of the product more beautiful, and it is easy to change the color without spraying, but it is expensive and requires high technology.
At present, in the process of preparing the two-color mold, the traditional process is still used, the processing procedure is too complicated, and the processing accuracy cannot be guaranteed

Abstract

The invention discloses a double-color die which comprises a bottom plate. Two sets of ejector pin fixing assemblies composed of ejector pin face plates and ejector pin bottom plates are arranged in the middle of the upper surface of the bottom plate in sequence from top to bottom. Guide pillar holes are formed in the four corners of the upper surfaces of the two sets of ejector pin fixing assemblies respectively. Guide pillars are arranged in the guide pillar holes. Springs are arranged on the guide pillars. A plurality of inclined tops and flat ejector pins which penetrate the two sets of ejector pin fixing assemblies and are fixed are further arranged in the middles of the upper surfaces of the two sets of ejector pin fixing assemblies. Fixing pillars are arranged in the positions, close to the two sets of ejector pin fixing assemblies, on the upper surface of the bottom plate, and the fixing pillars are sleeved with return pins. The double-color die can be well processed, and the processing efficiency of the die is ensured.

Description
