Multicolor injection molding mold and injection molding method thereof

Abstract

The invention discloses a multicolor injection molding mold. The mold comprises a base, a feeding box and an injection molding box, wherein the feeding box and the injection molding box are arranged on the base, the feeding box is located on one side of a top face of the base, the injection molding box is located on the other side of the top face of the base, the feeding box communicates with theinjection molding box through a communicating pipe, multiple sets of storage cylinders are arranged on the side, away from the injection molding box, of the top face of the feeding box side by side, afeeding mechanism is arranged in the feeding box, an injection molding mechanism is arranged in the injection molding box, an injection molding pipe is arranged in the injection molding box, a screwrod is arranged in the injection molding pipe, the screw rod is connected with an output end of the motor, a storage barrel communicates with a feeding end of the injection molding pipe through a feeding pipe, a discharging end of the injection molding pipe is connected with a feeding end of the injection molding mechanism through an injection molding communicating pipe, and the injection moldingcommunicating pipe is located in the communicating pipe. The mold can be formed through one-time injection molding step by step according to materials of different colors, the formed mold is automatically ejected out, the mold is convenient to replace, and mold products of different structures and sizes are formed through injection molding.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a multi-color injection mold, in particular to a multi-color injection mold and an injection molding method thereof. Background technique [0002] The multi-color injection mold is a multi-color injection mold with different colors, which is often used to form a whole injection molding process through two-color injection molding of a variety of different materials. [0003] The reference document CN201820325237.0 discloses a multi-color injection mold, including a first fixed mold and a second fixed mold, and a movable mold arranged between the first fixed mold and the second fixed mold. After the movable mold is closed with the first fixed mold and the second fixed mold, a corresponding injection molding cavity is formed at each injection station, and a station rotation mechanism is set on the second fixed mold. The mold is fixed on the rotating mechanism of this station. When the...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, the plastics of different colors used in multi-color injection molding often need to be re-opened when making products with different shapes. However, most of the existing plastic molds are formed at one time and cannot Processing forms a new mold, so it is necessary to make multiple sets of molds, which can only be completed after two-color mold opening and closing, which is time-consuming, laborious and wastes raw materials, requires repeated positioning, and the operation is cumbersome. , multi-color injection molds are inconvenient to disassemble. When it is necessary to produce molds of different structures and sizes, it takes time and effort to replace the molds, which is not efficient and quick enough, which reduces the work efficiency. A multi-color injection mold and its injection molding method are proposed
