High Quality Car Rearview Mirror Housing Mold

Automotive mirror covers, which are used to load the lenses of automotive mirrors, are plastic products with irregular exterior surfaces, usually manufactured by injection molding. The mold of the molding of the automobile mirror cover generally includes the upper mold and the lower mold, and the cavity that constitutes the product is formed between the upper and lower molds, and the molding process of the automobile rearview mirror is completed by injecting molten plastic into the cavity, and the mold is divided after molding.

In the related technology, the Injection mold construction usually has an injection hole connected with the injection molding machine on the upper mold of the Injection mold construction. The injection hole is connected with the cavity inside the upper mold. The injection molding machine connects with the injection hole to inject molten plastic into the cavity through the injection hole.

Due to the proximity of the injection hole to the external environment, after the injection molding machine stops injection molding, some of the molten plastic remaining on the inner wall of the injection hole and not flowing into the mold cavity is more likely to cool and solidify, causing blockage of the injection hole. It is necessary to frequently stop the processing of the injection mold for cleaning and maintenance, which is time-consuming and labor-intensive, and reduces production efficiency.
