Ejection mold for front mold sticking of double-color inverted mold product

Abstract

The invention discloses an ejection mold for front mold sticking of a double-color inverted mold product. The ejection mold comprises a first injection mold and a second injection mold. The first injection mold is provided with a first cavity formed by a first front mold core, a rear mold core, a first sliding block and multiple first oblique tops. The first cavity is used for manufacturing a one-color product. The second injection mold is provided with a second cavity formed by the one-color product, a second front mold core, a rear mold core, a second sliding block and a second oblique top. The second cavity is used for manufacturing a double-color product. The one-color product is provided with an auxiliary prosthesis and/or a groove. Each first oblique top comprises an oblique rod, a first clamping portion and a second clamping portion, wherein the first clamping portion and the second clamping portion are arranged at the two ends of the oblique rod correspondingly. The first clamping portions are used for being clamped with the auxiliary prosthesis or the groove in a matched manner. The second clamping portions are used for being connected with ejector pins. According to the ejection mold, by additionally arranging the first oblique tops, the product can be ejected smoothly in the mold stripping process, thus the problem of front mold sticking in the mold stripping process of the product is solved, the mold stripping effect is good, and productivity and stability of the product are met.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a two-color flip chip product sticking front mold ejection mold. Background technique [0002] Two-color plastic products through injection molding require two-shot molds to be molded sequentially. When one side of the product itself is flat, only flip-chip design can be used. Since one side of the product is flat and the thimble cannot be inserted, this When the product is out of the mold, it is easy to have the risk of sticking to the front mold, resulting in failure of the product out of the mold, resulting in high product failure rate, low efficiency, and increased cost. Contents of the invention [0003] The invention provides a two-color flip-chip product sticking front mold ejection mold, which aims to solve the problem of the existing mold sticking front mold when producing the above-mentioned products. [0004] In order to achieve the above object, the present inventio...
