Layered hot runner mold

Abstract

The invention relates to a layered hot runner mold, wherein runners in a shunting mechanism are communicated with runners in hot nozzles; the shunting mechanism consists of at least two layers of shunting plates and at least two layers of shunting nozzles; the two layers of shunting plates and the two layers of shunting nozzles are communicated with each other; the first layer of sprue bushings are arranged on the surface of a mold base panel; the number of the second layer of shunting nozzles is at least two, and the shunting nozzles are arranged between the two layers of shunting plates; the first layer of shunting plates and the second layer of shunting plates are respectively connected with the mold base panel and a hot runner subplate; both ends of each hot nozzle are respectively connected with a plate A and a front mold core, and at least four hot nozzles are arranged and sequentially arrayed. The layered hot runner mold has reasonable structural design and can carry out shunting operations on material solutions, carry out injection molding simultaneously through the hot nozzles, shorten the manufacturing and molding period, save plastic raw materials, reduce the waste, improve the production quality, eliminate subsequent working procedures and be beneficial to the production automation and the expansion of the application range of a molding process.

Description

technical field [0001] The invention belongs to the technical field of molds, in particular to a hot runner mold, especially a layered hot runner mold. Background technique [0002] Injection mold is a common mold in modern industrial production. Due to the influence of factors such as mold technology, injection volume of injection molding machine and volume modulus of injection molding machine, most of the molds for mass production of plastic products still stay in the traditional single-sided mold manufacturing process. superior. Due to the mutual constraints of factors such as the mold process, the injection volume of the injection molding machine, and the volumetric modulus of the injection molding machine, the invested equipment and energy cannot exert the best working efficiency. [0003] Hot runner mold is a kind of plastic injection molding mold commonly used at present. Compared with mold with cold runner structure, it has many advantages such as saving raw materia...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the hot runner plate in the existing hot runner mold has only one layer, split flow operation cannot be performed;

[0005] (2) Since the existing hot runner mold generally only has one hot nozzle, the number of hot nozzles is too small, which restricts the further improvement of product production efficiency
