Description

Technical Field

[0001] The utility model relates to the field of injection molding equipment, in particular to an injection molding raw material prefabrication device. Background Art

[0002] Before the solid raw materials for injection molding enter the injection molding machine for processing, they need to be heated to a molten state to provide molten raw materials for the subsequent injection molding process. At present, most injection molding processes are to directly inject the raw materials after heating and melting. When auxiliary materials need to be added, the auxiliary materials are directly added to the heating cylinder and then hot-melted and flowed into the feed port of the injection molding machine. The above method has the following defects: when the auxiliary materials follow the raw materials and enter the heating device at the same time, directly adding auxiliary materials during the heating process or adding auxiliary materials during the injection molding process may cause uneven mixing. Since the raw materials are not evenly melted, the auxiliary materials in the raw materials, such as additives or pigments, are not evenly distributed, which affects the appearance of the molded products and causes inconsistent colors of the finished products. At the same time, directly adding certain auxiliary materials at high temperatures can easily cause the auxiliary materials to degrade. Therefore, in order to solve the above problems, a kind of injection molding raw material prefabrication equipment is needed. Utility Model Content
