Multi-color injection molding device based on horizontal rotating

Abstract

The invention discloses a multi-color injection molding device based on horizontal rotating. The multi-color injection molding device based on horizontal rotating comprises a rack, a fixed mold plate(1), a moving mold plate (2), a pull rod (3), a mold moving oil cylinder (4) and injection stations. The fixed mold plate (1) is arranged on one side of the pull rod (3). The moving mold plate (2) sleeves the other end of the pull rod (3). The mold moving oil cylinder (4) is arranged on the rack. The piston end of the mold moving oil cylinder (4) is connected with the moving mold plate (2) so as to drive the moving mold plate (2) to move. The multi-color injection molding device further comprises a middle plate (5). The middle plate (5) is located between the fixed mold plate (1) and the moving mold plate (2). A first mold (10) is arranged between the moving mold plate (2) and the middle plate (5). A second mold (11) is arranged between the middle plate (5) and the fixed mold plate (1). Due to the adoption of the multiple multi-color injection stations, injection of two products can be achieved through one-time mold opening and closing; and meanwhile, the middle plate can be rotated according to needs, so that multi-color injection is achieved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine for injection molding of multi-color products, especially applicable to complex moulds. 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 the material itself of new polymer materials has also led to more and more applications in the market. In particular, there is an increasing demand for large plastic components as well as multi-colored plastic components. [0003] For single-color molds, the existing mainstream production method is basically one injection molding machine and one pair of molds, and one product is produced by opening and closing the mold at a time. The machine and mold are relatively simple, and a single injection ...

Problems solved by technology

When the vertical turntable hangs the mold, it will be subjected to an overturning moment of the mold. Although supports can be installed to counteract this force, there is a relatively large limit on the total weight of the mold. If the mold is too heavy, the vertical turntable cannot be used.

At the same time, the production efficiency of opening and closing the mold at most one product is insufficient, and it is difficult to meet people's needs for production efficiency and energy consumption reduction.

If the mold is more complicated, in order to realize multi-colored products on one side, the mold production will be extremely complicated, and the overall mold cost will increase geometrically. Ordinary injection molding machines cannot complete the production of medium and large molds. If production is required, a larger one needs to be purchased. the machine
