Description

Technical Field

[0001] This utility model relates to the field of automotive interior processing technology, specifically to an auxiliary mold mounting plate for automotive interior vacuum composite molds. Background Technology

[0002] The automotive interior system is a crucial component of the car body, and its design workload accounts for over 60% of the overall vehicle styling design workload, far exceeding that of the exterior. It is one of the most important parts of the car body. Interior panel materials include wood composite panels, metal composite panels, and plastic composite panels. Metal composite panels involve layering one metal sheet over another to achieve resource conservation and cost reduction without compromising performance (corrosion resistance, mechanical strength, etc.). Common lamination methods include explosive lamination, explosive rolling lamination, and rolling lamination. Composite materials can be categorized into composite panels, composite pipes, and composite rods. They are primarily used in corrosion protection, pressure vessel manufacturing, power construction, petrochemical, pharmaceutical, light industry, and automotive industries.

[0003] The auxiliary mold mounting plates of existing automotive interior vacuum composite molds are mostly inconvenient to unload. Sometimes the material sheets used for vacuum forming are adsorbed onto the surface of the mounting plate and need to be removed manually, which affects processing efficiency and poses certain safety hazards to workers. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the auxiliary mold mounting plate of the above and / or existing vacuum composite mold for automotive interiors, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an auxiliary mold mounting plate for a vacuum composite mold of automotive interiors. During use, the mold is placed on top of the mounting plate and vacuum-formed under the action of a vacuum pump. After vacuum forming, since the O-ring is slightly higher than the top of the mounting plate, the O-ring rebounds, and the material sheet separates from the top of the mounting plate under the action of the elastic force. The tapered screw prevents the O-ring from falling off during the unloading process. Under the action of the drive motor, the lifting frame is driven to rise, and the unloading rod lifts the material sheet at the four corners of the mounting plate to prevent the edges of the material sheet from sticking to the mounting plate. At the same time, the fixing frame slides along the second limiting groove through the cooperation of the first pulley and the second pulley. The second soft pad pushes the processed workpiece to automatically unload. This solves the problem that most auxiliary mold mounting plates of existing vacuum composite molds for automotive interiors are inconvenient to unload, and the material sheet used for vacuum forming sometimes adheres to the surface of the mounting plate, which requires manual removal, affecting processing efficiency and posing certain safety hazards to workers.
