Multi-material injection molding machine and multi-material injection molding method by adopting same

Abstract

The invention discloses a multi-material injection molding machine and a multi-material injection molding method by adopting the same. The multi-material injection molding machine comprises a glue injection unit, a fixed plate, a movable plate, an injection molding fixed mold base, an injection molding movable mold base, at least one PU fixed mold base and at least one PU movable mold base. The fixed plate is connected with the movable plate through a guide assembly; the injection molding fixed mold base and the at least one PU fixed mold base are arranged on the fixed plate, the injection molding movable mold base is arranged on the movable plate, and the injection molding movable mold base is opposite to the injection molding fixed mold base; the at least one PU fixed mold base is arranged; the at least one PU movable mold base is arranged on the movable plate, and the at least one PU movable mold base is in one-to-one correspondence with the corresponding PU fixed mold base; the output end of the glue injection unit communicates and is connected with the injection molding fixed mold base and the at least one PU fixed mold base; a first clamp is arranged between the at least onePU fixed mold base and the at least one PU movable mold base; and a second clamp is arranged between the at least one PU movable mold base and the movable plate. According to the multi-material injection molding machine and the multi-material injection molding method by adopting the same, injection molding and PU layer injection molding can be conducted on the same device, continuous production isachieved through cooperation of the multiple sets of mold bases, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a multi-material injection molding machine and a multi-material injection molding method thereof. Background technique [0002] Automotive interiors put forward higher requirements for color, touch, and intelligence. As a "smart" material, polyurethane is characterized by its softness, hardness, wear resistance, scratch resistance, self-repairing, and free color matching. , Bright color, friendly to "smart inserts" and other advantages, it is used in the preparation of interior components such as dashboards, center consoles, door panels and smart home appliances, and the number of applications is increasing year by year. [0003] The existing injection molding equipment generally adopts a one-time molding injection molding process. The semi-finished injection molded parts need to be transferred to other production equipment for PU layer processing. This separa...

Problems solved by technology

[0003] The existing injection molding equipment generally adopts a one-time molding injection molding process. The semi-finished injection molded parts need to be transferred to other production equipment for PU layer processing. This separate processing production method requires additional processing of the PU layer. The production line is too long and takes up a lot of space. At the same time, it is necessary to manually carry the semi-finished injection molded parts, which increases the labor intensity of the workers.
