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

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0031] Such as figure 1 with figure 2 As shown, a two-color mold includes a bottom plate 15. In the middle of the upper surface of the bottom plate 15, two sets of thimble fixing assemblies composed of a thimble panel 13 and a thimble bottom plate 14 are arranged in sequence from top to bottom. The four corners of the surface are respectively provided with guide post holes. The guide post holes are provided with a guide post 10, and the guide post 10 is provided with a spring 18. The two sets of thimble fixing components are also provided with several There are inclined top 11 and flat thimble 12 that pass through the two sets of thimble fixing components and are fixed. The upper surface of the bottom plate 15 is provided with a fixed post near the two sets of thimble fixing components. A guide sleeve 9 is provided on the end surface of the back pi...

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

Technical field [0001] The invention belongs to the field of mold processing, and specifically relates to a two-color mold and a preparation process thereof. Background technique [0002] The two-color mold is a mold in which two plastic materials are injected on the same injection molding machine and molded in two parts, but the product is only ejected once. Two-color molds are becoming more and more popular in the market. This process can make the appearance of the product more beautiful, easy to change the color without spraying, but it is expensive and requires high technical requirements. At present, in the preparation process of the two-color mold, the traditional technology is used, the processing procedure is too complicated, and the processing accuracy cannot be guaranteed. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a two-color mold and its preparation process for the above-mentioned shortcomings of the pri...
