Abstract

The invention discloses a plastic mold used for an automotive interior. The plastic mold comprises a mold body. The center of the mold body is provided with a main runner and cooling water channels. The cooling water channels are arranged on the two sides of the main runner. An auxiliary runner is arranged at the lower end of the main runner and perpendicular to the main runner. A first hot nozzle, a second hot nozzle and a third hot nozzle are arranged on the auxiliary runner and connected with spouts of the auxiliary runner through sealing rings correspondingly. According to the plastic mold used for the automotive interior, the structure and the principle are simple; the adopted main runner and the adopted auxiliary runner are both hot runners, and thus the material cost can be reduced; and the auxiliary runner is provided with the multiple nozzles, and hence the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold for automotive interior decoration. Background technique [0002] Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, and the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also varied. Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature adjustment system, molding parts and structural parts. Among them, the pouring system and molding parts are the parts that are in direct contact with the plastic and ...
