Injection molding method for multicolor products

Abstract

The invention discloses an injection molding method for multicolor products. The injection molding method for the multicolor products is based on a multicolor-product injection molding machine which comprises a machine frame, a fixed die plate (1), a movable die plate (2), a pull rod (3), a die moving oil cylinder (4) and injection tables, the fixed die plate (1) is arranged at one end of the pullrod (3), the movable die plate (2) sleeves the other end of the pull rod (3), the die moving oil cylinder (4) is installed on the machine frame, and the piston end of the die moving oil cylinder (4)is connected with the movable die plate (2) to drive the movable die plate (2) to move; and a middle plate (5) and a middle plate rotating mechanism (6) are arranged between the fixed die plate (1) and the movable die plate (2), the middle plate (5) is fixed to the middle plate rotating mechanism (6), the middle plate rotating mechanism (6) drives the middle plate (5) to rotate, two sides of the middle plate (5) are both used for installing dies. According to the injection molding method for the multicolor products, the multiple injection tables are adopted, injection of the two products can be realized by once die opening and closing, and meanwhile, multicolor injection can be realized by rotating the middle plate according to the needs.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding method for multi-color products, especially applicable to complex moulds. Background technique [0002] Paragraph 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 station can ...

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
