Description

Double-mold production device of clear double-color injection molding machine

Technical Field

The utility model relates to the technical field of double-mold production of double-cyan injection molding machines, in particular to a double-mold production device of a clear double-color injection molding machine.

Background

The movable template position of the mold locking part of the prior clear double-color injection molding machine is respectively provided with two devices:

a rotary plate type clear double color is characterized in that a male die A1 is arranged in front of the rotary plate, and a male die B1 is arranged behind the rotary plate, and the male die A1 and the male die B1 can be matched with front and rear female dies A2 and B2 on a fixed template to form a die cavity. When a product is injection molded for the first time, firstly, B-color plastic is injection molded into a mold cavity formed by B1 and B2 on the back of a turntable, a semi-finished product with the B color is obtained on a male mold B1 of the turntable, then, after the turntable rotates 180 degrees, a B1 male mold of the semi-finished product with the B color of the turntable is rotated to the front, and an A1 male mold on the turntable is rotated to the back of the turntable, at the moment, a B1 male mold of the semi-finished product with the B color of the turntable and an A2 female mold on a fixed mold plate form a mold cavity, then, the A-color plastic is injection molded into the mold cavity to form a product with the two colors of A and B, and the A1 male mold on the turntable and the B2 female mold on the back of the fixed mold plate can also injection mold the B-color plastic to form the semi-finished product with the B color. The turntable rotates 180 degrees in a reciprocating way, and the machine can continuously inject and mold products with colors A and B. Such as a bi-colored vehicle light panel.

The other is a rotary die core type clear double color. At the moment, a transition plate is installed on the movable template, 1 male die is installed on the transition plate, the front of each male die is an A1 die core, the back of each male die is a B1 die core, the two die cores are connected with a die core connecting seat of a rotary die in a die core rotating device, a female die is also installed on the fixed template, the front of the female die is provided with an A2 die cavity, and the back of the female die is provided with a B2 die cavity. During the first injection molding, a product mold cavity formed by the male mold core B1 and the female mold cavity B2 is subjected to injection molding by using B-color plastic to obtain a semi-finished product with B color, then the semi-finished product with B color, namely the male mold core B1, is rotated to the front by rotating the mold core shaft for 180 degrees, at the moment, the male mold core B1 with the B-color semi-finished product and the front female mold cavity A2 on the fixed mold plate form, and the formed product mold cavity is subjected to injection molding by using A-color plastic to form a product with A and B colors. And meanwhile, a product mold cavity formed by the A1 mold core on the male mold and the B2 rear female mold cavity on the fixed mold plate is also subjected to injection molding by the B-color plastic, so that a semi-finished product with the B color is obtained. The rotary die core shaft rotates 180 degrees in a reciprocating way, and the machine can continuously inject and mold products with colors A and B. Such as a two-color pen cap. At present, the two types of moulds manufactured by double-color injection moulding need to be matched with corresponding devices, so that two machines are needed. For a double-color mold manufacturing factory, the main task of the clear double-color injection molding machine is to test the two molds, and the investment is large. It is desirable to test the two molds separately with one machine, so we propose a double mold production device for a dual color injection molding machine to solve the above mentioned problems.
