Embodiment 1

[0015] Embodiment 1: A two-color injection molding process. The two-color injection molding process uses a two-color molding machine with a molding die to form a two-color molding product. The two-color molding machine is provided with a first-color injection area and a second-color injection area. The two-color molding machine has The turntable, the forming mold includes a male mold and a female mold, the male mold is set on the turntable, and the two-color molded product includes a first color part and a second color part.

[0016] The two-color injection molding process includes the following steps:

[0017] (1) Form the first color part in the first color injection area by conventional methods;

[0018] (2) Turn the turntable after the mold is opened, and the turntable drives the male mold to the second-color injection area, where the second-color part is formed by in-mold transfer molding process, and the raw material of the second-color part is transparent material; The...

Abstract

The invention relates to a double-color injection molding process. A double-color molding product is molded by using a double-color molding machine provided with a molding die; the double-color molding machine is provided with a first color injecting area, a second color injecting area and a turntable; the molding die comprises a male die and a female die, wherein the male die is arranged on the turntable; and the double-color molding product comprises a first color part and a second color part. The double-color injection molding process comprises the following steps of: (1) molding the firstcolor part in the first color injecting area; (2) turning the turntable after the die is opened, wherein the turntable drives the male die to turn to the second color injecting area, and molding the second color part in the second color injecting area by adopting an in-mold transfer molding process, wherein the second color part is made of a transparent raw material; and (3) obtaining the double-color molding product after the die is opened. As the double-color injection molding process is adopted, both the appearance of a transfer film and the appearance of the first color part can be presented while efficiency is increased and the production process is shortened, so that the molding product has the advantages of more attractive appearance, three-dimensional effect and gradation.

Description

technical field [0001] The invention relates to a two-color injection molding process. Background technique [0002] In the prior art, when molding two-color molding products, two molding machines are usually used. First, the first color part is injected and formed on the first molding machine. Injection molding second color part. Due to the need to use two molding machines, the production cycle is longer and the cost is higher, and the appearance of the two-color molding product is not beautiful enough. Contents of the invention [0003] The purpose of the present invention is to provide a two-color injection molding process that shortens the manufacturing process and beautifies the appearance of the molded product. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A two-color injection molding process. The two-color injection molding process uses a two-color molding machine with a molding die to form a tw...
