Description

Technical Field

[0001] The utility model relates to the technical field of molds, and specifically to a mold for high-speed injection molding. Background Technique

[0002] An injection mold is a tool for producing plastic products and also a tool for endowing plastic products with a complete structure and precise dimensions. Injection molding is a processing method used when mass-producing some parts with complex shapes. Specifically, it means injecting the heat-melted plastic into the mold cavity at high pressure by an injection molding machine, and after cooling and solidifying, a formed product is obtained. However, if the mold design or operation is improper, there may be gas inside the mold. When the mold is opened, some gas may be released from the mold. Since these gases are volatiles generated by the plastic material during the injection process, they are somewhat toxic, and long-term inhalation by workers will affect their physical health. In view of this, we propose a mold for high-speed injection molding to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a mold for high-speed injection molding to solve the problems raised in the above background technique.
