Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The existing two-color injection molding mold adopts rotation or translation to realize injection molding, or adopts the mode of making two sets of moulds. The invention effectively reduces the complexity of the mold through a set of molds, and the processing technology is more convenient and optimized.

[0027] Such as figure 1 As shown, a two-color injection molding mold of the present invention includes: a panel 1 and a hot runner plate 2 arranged o...

Abstract

The invention provides a double-shot injection mold. The double-shot injection mold comprises a panel, a hot runner plate and a bottom plate, wherein the panel and the hot runner plate are arranged at the top; the bottom plate is arranged at the bottom; oil cylinders are arranged on the upper surface of the bottom plate and drive a sealing blade propping plate to move through connecting blocks; one end of a sealing blade propping rod is connected and fixed with the sealing blade propping plate through a cushion block, and a sealing blade is fixed at the other end of the sealing blade propping rod. The double-shot injection mold is compact and simple in structure, so that the mold is lighter in weight and more reliable in movement, the mold cost is reduced, and the production efficiency of products is improved; the mold is compact in structure, so that the length, the width and the height of the mold are reduced, the mold can be produced through smaller injection molding equipment, and the equipment energy consumption is reduced; the mold is not required to be opened during production, so that damage to appearances of the products during opening and closing of the mold is avoided, and the appearance quality of the products is well guaranteed; during injection molding of two materials, the time is short, the product heat loss is low, and the two materials are higher in bonding strength and not easy to fall off.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a two-color injection molding mold, and also relates to a two-color injection molding method. Background technique [0002] Soft and hard rubber overlapping products are common in auto parts. This kind of soft and hard rubber overlapping products is mainly injection molded through the existing two-color injection molding mold. The existing two-color injection molding mold is mainly made of two front molds and one rear mold. , by rotating or translating the rear mold, or making two sets of molds, injecting one material into another set of molds to realize the combination of the two materials. [0003] The existing two-color injection molding mold has high cost, low production efficiency, poor product appearance quality, and poor bonding strength of the two materials, which are easy to fall off. Contents of the invention [0004] The invention proposes a two-color injection mold...
