Multicolor product injection molding machine

Abstract

The invention discloses a multicolor product injection molding machine. The multicolor product injection molding machine comprises a rack, a fixed mold plate (1), a movable mold plate (2), pull rods (3), a mold transfer oil cylinder (4) and injection molding platforms, wherein the fixed mold plate (1) is arranged at one ends of the pull rods (3), the movable mold plate (2) sleeves the other ends of the pull rods (3), the mold transfer oil cylinder (4) is installed on the rack, and the piston end of the mold transfer oil cylinder (4) is connected with the movable mold plate (2) to drive the movable mold plate (2) to move. The multicolor product injection molding machine furthermore comprises an intermediate plate (5) and an intermediate plate rotation mechanism (6), wherein the intermediateplate (5) is fixed to the intermediate plate rotation mechanism (6), the intermediate plate rotation mechanism (6) drives the intermediate plate (5) to rotate, and the two sides of the intermediate plate (5) are both used for installing molds. According to the multicolor product injection molding machine, a plurality of injection molding platforms are adopted, and two products can be injection-molded simply by conducting mold opening and closing once; meanwhile, the intermediate plate can be rotated as required to achieve multicolor injection molding.

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
