Abstract

The invention discloses a double-color injection mold. The double-color injection mold comprises a first-color female mold, a second-color female mold, a first-color male mold and a second-color male mold, and a first-color glue channel is arranged in the first-color male mold; a second-color glue channel is arranged in the second-color female mold; the first-color male mold and the second-color male mold can be assembled with the first-color female mold to form a first-color cavity, and the first-color male mold and the second-color male mold can be assembled with the second-color female mold to form a second-color cavity; the first-color male mold and the second-color male mold are arranged on a turntable, and the turntable can drive the first-color male mold and the second-color male mold to rotate; a first nozzle communicating with the first-color glue channel is arranged beside the first-color male mold; a second nozzle communicating with the second-color glue channel is arranged on the top side of the second-color female mold; and the double-color injection mold further comprises a film feeding machine used for conveying a film to the first-color female mold. The invention further relates to an IMR forming method using the mold, glue leakage caused by switching of the female molds to the male molds can be avoided, the forming pressure is reduced, and the effect of an injection-molded product is good.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a two-color injection mold and an IMR molding method thereof. Background technique [0002] Two-color injection molding refers to a molding process in which two different materials are injected into the same set of molds, so that the injection molded parts are formed from two materials. Some two materials are of different colors, and some are of different hardness and softness, so as to improve the aesthetics and assembly performance of the product. [0003] IMR (In-Mould Decoration by Roller), the Chinese name is in-mold decoration technology, which is to print decorative patterns and functional patterns on the foil film (film) through a high-precision printing machine, and send the foil into the film through a high-precision foil feeding device. After precise positioning in the special molding mold, the pattern on the foil film is transferred to the surface of the pl...
