Three-color nano-rubber eva injection mold

Abstract

The invention discloses a three-color nano-rubber EVA (Thylene-Vinyl Acetate) injection die. The three-color nano-rubber EVA injection die comprises an upper die assembly and a bottom die assembly, wherein the upper die assembly comprises an upper die separating plate and an upper die which are matched with each other; the upper die and the upper die separating plate can be combined, and an upper die core for forming a third-color finished product is arranged in the combination; the bottom die assembly comprises a bottom die separating plate and a bottom die which are matched with each other; the bottom die and the bottom die separating plate are combined, and a bottom die core for forming a first-color finished product and a second-color finished product is arranged in the combination; injection ports for pouring the nano-rubber EVA are formed in the side edges of the same sides of the upper die assembly and the bottom die assembly; a third-color injection port is formed in the upper die assembly; a first-color injection port and a second-color injection port are formed in the bottom die assembly; the first-color injection port, the second-color injection port and the third-color injection port correspondingly communicate with a first-color material channel, a second-color material channel and a third-color material channel which extend to the upper die core and the bottom die core.

Description

technical field [0001] The invention relates to an EVA injection mold for making shoes, specifically for making shoe soles. Background technique [0002] With the improvement of people's living standards, consumers have more pursuits for the color and style of shoes; this demand is reflected in the pursuit of more colors for soles; the current way of producing soles with three colors must be through the development of three colors. Set a single-color mold, and use rubber or paint to achieve a three-color effect; the production process is time-consuming, laborious, costly, and wasteful; [0003] At the same time, in the prior art, after each opening of the EVA injection mold for traditional shoemaking, the operator must clean up the residue on the surface of the mold, which is time-consuming, laborious and costly. Contents of the invention [0004] The technical problem to be solved by the present invention is to disclose a three-color nano-rubber EVA injection mold for th...
