Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to a heat insulation structure for a pen barrel injection mold. Background Technique

[0002] Mold injection molding is a processing method used in mass production of certain shaped parts. Specifically, the heated and melted plastic raw materials are pushed by an injection molding machine and injected into the cavity of a plastic mold under high pressure. After cooling and solidification, a plastic molded product is obtained. With the continuous increase in the demand for plastic products, improving the efficiency of injection molding has always been a concern. Therefore, in the injection molding process, the application of multi-cavity injection molds containing multiple cavities is becoming increasingly widespread. It can simultaneously realize the processing and molding of multiple products, which can significantly improve production efficiency. For example, the injection molding of pen barrels is produced using a multi-cavity mold. The pen barrel injection mold is not provided with a heat insulation structure. During the operation of the pen barrel injection mold, high-temperature raw materials will be injected into the interior of the injection mold, resulting in a relatively high overall temperature of the injection mold. In the production workshop during the processing operation, if workers are not careful, it is easy to cause burns to the workers.
