Automatic release mode two-color continuous injection mold

Abstract

The invention discloses an automatic demoulding type two-color continuous injection mould which comprises two male die components; a cooling core sleeve is fixedly arranged on each of the male die components; a waterway core shaft is fixedly arranged in the cooling core sleeve; an ejector pin is mounted in the waterway core shaft in a penetrating manner; a top block is fixedly arranged at the topend of the ejector pin; a water entering passage, a water returning passage and a water passing annular groove are formed in the waterway core shaft; a thread demoulding core sleeve is movably mountedon the external part of the cooling core sleeve in a sleeving manner; an injection thread die is arranged at the top end of the thread demoulding core sleeve; a demoulding guiding thread is formed inthe bottom end of the thread demoulding core sleeve; a demoulding guiding screw hole is formed in each of the male die components; demoulding driving cylinders are fixedly arranged on the near sidesof the two male die components; a demoulding driving sliding block on the upper side is fixedly arranged at the end part of the piston rod of each of the demoulding driving cylinders; a demoulding driving rack is fixedly arranged on the demoulding driving sliding block; and a gear drive is arranged between the demoulding driving rack and the thread demoulding core sleeve. The automatic demouldingtype two-color continuous injection mould realizes cooperative application of oil cylinder rack driving and a core rotary split type die, realizes continuous efficient injection molding, and ensures the product quality after injection molding.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an automatic release mode two-color continuous injection mold. Background technique [0002] Two-color injection molds can be classified according to mechanism: core rotary type, core retreat type, and push plate rotary type. Among them, the core rotary type can be divided into two types: split type and conjoined type. The so-called split type uses two sets of molds installed on one injection molding machine to complete the injection molding of two-color products. Injection molding of two-color products is completed. Among them, the core rotating split type is widely used due to its advantages of low cost and strong adaptability. [0003] For injection molding products with threads, a thread release structure will be added to the mold. The driving methods of the threaded demoulding structure include: oil cylinder with rack drive, motor with chain drive, motor with beve...

AI Technical Summary

Problems solved by technology

At present, there is no existing technology that can integrate the above-mentioned structural functions, so that the production of threaded two-color injection molding products cannot be used on existing core rotary split two-color injection molds
