Automobile interior trim part injection mold

Abstract

The invention provides an automobile interior trim part injection mold comprising a storage battery, a first fixed plate, a first groove, a second groove, a second fixed plate, a sound absorption plate, an exhaust pipe and an exhaust fan. The storage battery is installed in the first fixed plate. The first fixed plate is fixed to the left end of the annular side face of a hollow column and is assembled in the first groove. The first groove is formed in the left portion of the upper end face of a movable mold plate. The second groove is formed in the right portion of the upper end face of the movable mold plate. The second fixed plate is fixed to the right end of the annular side face of the hollow column and is assembled in the second groove. By means of the design, the functions of heating residual materials and conveniently removing the residual materials are achieved. The sound absorption plate is assembled in a containing box. The right end of the exhaust pipe is connected with theexhaust fan. The exhaust fan is installed in the containing box. By means of the design, the functions of extracting air in an injection molding cavity, increasing the product percent of pass and reducing noise are achieved. The automobile interior trim part injection mold is convenient to use, good in residual material removal effect, high in product percent of pass and good in reliability.

Description

technical field [0001] The invention relates to an injection mold for an automotive interior part, which belongs to the field of auto parts processing equipment. Background technique [0002] In the prior art, there are often cooling residues left in the injection hole, which requires the operator to use a mechanical arm to remove the residue in the injection hole before each injection, and the removal of the residue is not complete, which increases the rate of defective products. [0003] In the prior art, air bubbles are often formed in the product during injection molding because the air in the injection cavity is not exhausted, making the product unusable. Therefore, an injection mold for automotive interior parts is urgently needed to solve the above-mentioned problems. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an injection mold for automotive interior parts to solve the problems r...
