Description

Rotary glue feeding mold

[ technical field ] A method for producing a semiconductor device

The utility model relates to an injection molding advances gluey technical field, in particular to rotatory gluey mould of advancing.

[ background of the invention ]

Injection molding, also known as injection molding, involves stirring a completely molten plastic material at a certain temperature with a screw, injecting the material into a mold cavity at a high pressure, and cooling and solidifying the material to obtain a molded article. It is a molding method of injection and molding. The injection molding method has the advantages of high production speed, high efficiency, automation of operation, various colors, various shapes from simple to complex, small sizes, accurate product size, easy replacement of products, capability of forming products with complex shapes, and suitability for the molding processing fields of mass production, products with complex shapes and the like. The method is suitable for mass production of parts with complex shapes, and is one of important processing methods.

The gate, also called a feed port, refers to a section of the channel from the runner to the mold cavity, which is the smallest and shortest section in the runner system. The function is that the feeding material is accelerated by utilizing the constricted flow surface, and the high shear rate can ensure that the feeding fluidity is good; the heating effect of viscous heating also has the function of increasing the temperature and reducing the viscosity of the material. The sprue is firstly solidified and sealed after the molding is finished, so that the functions of preventing feeding backflow and avoiding the shrinkage and depression of the molded product caused by too fast pressure drop of the cavity are achieved. After molding, the runner system and the molded part are conveniently cut off. The sprue is a feed channel connecting the runner and the cavity, and has two functions: firstly, controlling the plastic melt to flow into a cavity; secondly, after the injection pressure is removed, the cavity is sealed, so that the plastic which is not cooled and solidified in the cavity cannot flow backwards. The choice of gate type will depend on such factors as the requirements of the appearance of the article, the constraints on size and shape, and the type of plastic used.

The side gate is also called a rectangular gate. It is generally placed on the parting plane and fed from the outside of the cavity. Since the side gates are generally small in size, the relationship between the cross-sectional shape and the pressure and heat loss is negligible. The side gate has simple shape, convenient processing, easy and accurate control of size and easy and quick change, and is suitable for all plastic materials except polycarbonate. The disadvantage is that it is easy to produce flow marks during forming, and is not suitable for thin plate-shaped transparent products, and also not suitable for thin and long barrel-shaped products. The product has obvious sprue flaws on the surface, and the pouring channel needs to be cut off manually.

Referring to fig. 1 and 2, a mold for injecting glue in a rotating manner includes a sleeve-shaped plastic member 1, a runner, and a gate 2. The pouring gate 2 is positioned at the inner side wall of the plastic part 1. The inside wall is hidden easily and is advanced gluey, and the runner should set up in the shaping goods thick wall department, makes the plastic follow thick wall flow to thin wall department to reduce the loss of pressure. The plastic melt should be injected into the mold cavity quickly, with a minimum of path, heat and pressure loss, to complete the injection molding. The runner is a flow channel for the molten plastic ejected from the nozzle of the injection molding machine and should be designed to have low resistance and prevent cooling. In the exemplary embodiment, the flow channels are designed in a trapezoidal or circular manner.
