Vertical type double-color injection molding machine

Abstract

The invention relates to a vertical type double-color injection molding machine. The vertical type double-color injection molding machine comprises a machine frame, wherein the machine frame comprisesat least two injection molding devices, a mold closing device and a rotary disc device; the mold closing device and the rotary disc device are matched with the injection molding devices; the mold closing device comprises an upper mold plate and a guide column, and the guide column is used for supporting the upper mold plate; the machine frame comprises an operation table, the operation table is penetrated into the guide column, and the rotary disc device is rotationally arranged on the operation table; the mold closing device is positioned at the lower end of the operation table; a mold is positioned between the rotary disc device and the upper mold plate. The vertical type double-color injection molding machine has the advantages that the mold can be rotated by the rotary disc device, and the rotary disc is rotated by using the support seat as the center of circle; the structure is stable, and the easiness in deflection is avoided; a motor is used for controlling, so as to avoid deflection in the mold closing process; the mold closing device can supply enough mold locking force for the mold, so as to prevent the flash and other poor conditions of the product because of existenceof the gap between the upper mold assembly and the lower mold assembly due to unenough mold locking force.

Description

technical field [0001] The invention relates to a vertical two-color injection molding machine, in particular to a vertical two-color injection molding machine related to the technical field of injection molding equipment. Background technique [0002] Two-color or multi-color injection molding machine injection molded products are formed by mixing the same raw material into two or more different colors. After the first injection is completed by the plasticizing injection device and the mold, the molding mold can be rotated and transposed. Two or more times to complete the action of injecting molten materials of different colors into the same molding mold to obtain two-color or multi-color injection molded products. [0003] The existing two-color or multi-color injection molding machines need to manually rotate the injection mold to realize the conversion of the mold position. On the one hand, the labor intensity of the workers is high. On the other hand, due to manual oper...

AI Technical Summary

Problems solved by technology

[0003] The existing two-color or multi-color injection molding machines need to manually rotate the injection mold to realize the conversion of the mold position. On the one hand, the labor intensity of the workers is high. On the other hand, due to manual operation, the accuracy of manual operation is not high when the mold position is changed. It leads to differences in the size of the product during injection molding, which leads to a decrease in the pass rate of the product and increases the production cost
