Description

TECHNICAL FIELD

[0001] The utility model relates to blow mould technology field, concretely relates to an improved structure of automobile spoiler blow mould. BACKGROUND

[0002] The automobile spoiler has a hollow structure and needs to be blow molded. In order to realize the blow molding of the spoiler, a special automobile spoiler blow mold needs to be matched. The blow mold in the prior art usually comprises a left mold plate and a right mold plate. The left mold plate and the right mold plate are provided with a cavity surface on the mutually opposite surfaces. After the left mold plate and the right mold plate are moved and closed, the cavity surfaces thereof form a blow molding cavity of the spoiler. After the blow mold is completed, it needs to be installed on an injection molding machine. The installation of the blow mold comprises installing the left mold plate and the right mold plate on two movable closing seats of the injection molding machine, so that the left mold plate and the right mold plate can be moved and closed.

A blowing needle is usually arranged on the left mold plate or the right mold plate. After the left mold plate and the right mold plate are closed, the blowing needle penetrates into the hollow tubular glue to blow air, so that the hollow glue expands and adheres to the cavity surface of the blow molding cavity, thereby realizing the blow molding of the glue. In order to accelerate the solidification of the glue after blow molding, cooling channels are arranged on the left mold plate and the right mold plate. By inputting flowing cooling water into the cooling channels, the left mold plate and the right mold plate can be cooled. After cooling, the mold is opened and the part is taken out, thereby obtaining the blow molded part of the automobile spoiler.
