Novel horizontal rotating correlation multi-component injection molding device

Abstract

The invention relates to the technical field of injection molding machines, solves the problems of low rotation precision and unsmooth rotation of an intermediate plate in an injection molding device in the prior art, and particularly discloses a novel horizontal rotation correlation multi-component injection molding device which comprises a rack, a fixed mold plate, a movable mold plate, a pull rod, the intermediate plate, a first injection table and a second injection table, the middle plate is rotatably arranged on the rack through the rotating mechanism, the rotating mechanism comprises the rotary table platform assembly and the platform sliding plate assembly, the platform sliding plate assembly and the rotary table platform assembly can provide up-down support for rotation of the middle plate, so that rotation of the middle plate is more stable, and meanwhile the platform sliding plate assembly and the rotary table platform assembly can slide at the same time; the rotary table platform assembly is connected with the copper gasket immersed in the oil, dry grinding between the rotary table and the platform base is prevented, the rotating smoothness of the rotary table can be improved, and then the rotating smoothness of the middle plate is improved, so that mold breaking or mold opening and closing force and up-down force application are applied to the middle plate, the stress is more uniform, and the rotary table platform assembly is connected with the copper gasket immersed in the oil liquid to prevent dry grinding between the rotary table and the platform base.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a novel horizontally rotating butt-shot multi-component injection molding device. Background technique [0002] In recent years, with the improvement of environmental protection awareness and supervision, the trend of replacing traditional raw materials with polymer recyclables has become greater. At the same time, the development of new polymer materials has also led to more and more applications in the market, especially for large There is an increasing demand for plastic components as well as multi-coloured plastic components. [0003] For single-color molds, one injection molding machine and one pair of molds are used now, and one product is produced by opening and closing the mold at a time. The machine and mold are relatively simple, and one injection station can be matched with one mold; for multi-color molds, the existing technology In the process, an ...

Problems solved by technology

However, in the prior art, one installation method of the intermediate plate is: the intermediate plate is generally installed on the base through a rotating shaft, and dry grinding usually occurs between the intermediate plate and the base, and the resistance of the forward and reverse rotation of the intermediate plate is relatively large , the rotation is not smooth, and when the middle plate rotates, its positioning accuracy is poor, and the product accuracy is also poor; another installation method is: the middle plate is installed on the base through a rotating shaft, and its bottom is supported by several oil cylinders, which can ensure Smooth rotation, but consumes a lot of energy and has a complex structure
