Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a rapid molding injection mold for plastic accessories. Background Art

[0002] Plastic products are a general term for daily necessities and industrial products made of plastic as the main raw material. They include products made from injection molding, vacuum forming and other processes using plastic as raw material. Plastic is a type of synthetic polymer material with plasticity. Plastic accessories are mostly manufactured through injection molds during the production process. Injection molding is also called injection molding. It is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, shapes from simple to complex, sizes from large to small, and precise product sizes. The product is easy to update. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is one of the important processing methods.

[0003] However, some injection molds are unable to cool down the plastic workpiece in time after injection molding. When the molded workpiece is manually removed, it is easy to burn the staff due to the hot workpiece. The traditional method is natural cooling, which has low cooling efficiency, thereby reducing production efficiency. For this reason, we propose a rapid prototyping injection mold for plastic accessories to solve the above problems. Utility Model Content
