Description
Technical Field
[0001] The utility model belongs to the technical field, and in particular relates to a raw material extrusion device for automobile injection molding products. Background Art
[0002] Many automotive parts often require injection molding. The principle is to push the heated, melted plastic raw material through the injection molding machine screw and inject it into the mold cavity of the plastic mold under high pressure. After cooling and solidification, the plastic molded product is obtained. Existing raw material extrusion devices for automotive injection molding products can meet the basic needs of extruding the raw materials required for automotive injection molding products and can improve the efficiency of raw material extrusion by providing multiple extrusion ports, thereby improving the efficiency of automotive injection molding product production and processing. However, since the multiple injection ports are usually fixed and the spacing between the extrusion ports is not adjustable, and the extrusion device does not have a flexible and adjustable material guide structure after the raw material is discharged from the extrusion ports and falls into the injection mold below, it can only be used in situations where the positions of multiple injection molds are also fixed and compatible with the extrusion ports, and therefore cannot fully meet people's usage needs.
[0003] For example, the utility model with the announcement number CN 216609979 U discloses an extrusion feeding mechanism for an automobile connector injection mold. In the technical solution of this patent, the bottom of the hot melt device is fixedly connected to an extrusion feeding device, a discharge valve is provided inside the extrusion feeding device, the bottom of the extrusion feeding device is fixedly connected to a separation box, and several feed ports are provided at the bottom of the separation box, and an assembly port is provided at the bottom of the feed port. Since the positions of the multiple feed ports are fixed and cannot be adjusted, and there is no adjustable material guide module for flexibly adjusting the discharge process of the raw materials, the device can only make the molding mold fixedly set to adapt to the working conditions of multiple feed ports, which cannot fully meet people's usage needs.
