Electric heating type automobile interior foam molding mold

Abstract

The invention provides an electric heating type automobile interior foam molding mold comprising a bottom frame, a positioning ring, a dust filter net, a protective cover, a rotating rod, a rotating groove, a second connecting ring, a rotating shaft, a rotating frame, a filter net, a fan and a bracket. The bottom frame is assembled in an upper vent hole, the positioning ring is arranged on the upper end surface of the bottom frame, the dust filter net is installed in the positioning ring, the protective cover is assembled on the upper end surface of the bottom frame, and the rotating rod is installed in a connecting seat. By means of the design, the functions of efficient dust proofing and convenient replacement are achieved; the rotating groove is arranged in the front end surface of a lower mold, the rotating shaft is assembled in the rotating groove, the rotating frame is assembled on the annular side face of the rotating shaft through the second connecting ring, the filter net is installed on the front end surface of the rotating frame, the bracket is arranged on the inner annular side surface of the rotating frame, the fan is mounted on the upper end surface of the bracket, and therefore the design realizes the function of conveniently cleaning dust in a lower vent hole, and the exhaust and heat dissipation performance of the mold are improved; and the electric heating type automobile interior foam molding mold is convenient to use, convenient to operate, good in stability and high in reliability.

Description

Technical field [0001] The invention is an electric heating type foam forming mold for automobile interior decoration, which belongs to the technical field of automobile molds. Background technique [0002] The car door trim panel is one of the important parts of the car. It can be used to install various switch panels, storage, etc., but its most important role is the use of riding safety. The door trim panel has also become a passive vehicle. An important component indispensable for safety. In recent years, the use of polyurethane foam in automobiles has gradually increased. Flexible polyurethane foam is used in automobile seat cushions and dashboards to improve vehicle comfort. Rigid polyurethane foam is used in bumpers, Car door interior panels and other parts improve the absorption capacity of vehicle collisions. At present, the structure of the foam forming molds for interior panels currently used mainly includes an upper mold and a lower mold. Heating rods are evenly arran...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, a large amount of dust falls into the upper mold from the upper vent hole during the processing of the electric heating type automotive interior foam molding mold, which affects the use of the mold and reduces the processing efficiency. In the prior art, the electric heating type The lower mold of the automotive interior foam molding mold is equipped with an exhaust heat dissipation device. The dust falls into the exhaust heat dissipation device and is difficult to clean up, which affects the heat dissipation of the lower mold. Therefore, an electric heating type automotive interior foam molding mold is urgently needed to solve the above problems.
