Description

[0002] A mold is required for the production of the wind hood. The two sets of customized templates are sealed and merged by injection molding. The molten wind hood material is injected into the inside. After cooling and molding, the mold is demolded and trimmed to form the wind hood.

[0003] Existing wind hood molds, such as the injection mold proposed in patent application number "CN202223470035.0", avoid left and right displacement through structures such as inserts, positioning grooves, upper templates, and lower templates, and more accurately limit the opening and closing of the upper and lower templates.

[0004] However, when the upper mold and the lower mold are closed, the lower mold and the upper mold are subjected to a certain impact on each other, which may easily cause damage to the lower mold or the upper mold.
