Constant-temperature hot-pressing coating tool for automotive interior trim

Abstract

The invention relates to a constant-temperature hot-pressing coating tool for an automotive interior trim. The constant-temperature hot-pressing coating tool comprises a base, a top plate arranged above the base, a movable plate arranged between the base and the top plate, a lower die arranged on the movable plate and an upper die arranged at the bottom of the top plate. The lower die comprises a lower cavity formed in the top of the lower die, a plurality of hot runners which are arranged in the lower die in parallel and penetrate through the two sides of the lower die, and a plurality of water pipes for sequentially connecting the plurality of hot runners end to end. The upper die comprises an upper cavity formed in the bottom of the upper die, a plurality of avoiding holes vertically formed in the upper die, communicated with the upper cavity and used for containing mounting columns and clamping feet of an interior trim panel respectively, and a plurality of locking mechanisms arranged in the upper die and used for locking the clamping feet to fix the interior trim panel in the upper cavity. The interior trim panel and a veneering material are fixed on the upper die and the lower die respectively, automatic hot-pressing coating can be realized, and the lower die can realize constant temperature through the plurality of hot runners, so that the coating effect and precision are greatly improved.

Description

technical field [0001] The invention relates to the field of coating equipment, in particular to a constant-temperature hot-press coating tool for automotive interior parts. Background technique [0002] With the rapid development of automobile technology, a large number of new technologies, new materials and new processes have been widely used in automobiles, which has greatly improved the power, economy, safety, emission and comfort of automobiles. In order to meet the user's requirements for automobile interiors, the automobile manufacturing industry currently adopts the method of covering the interior panels with veneer materials such as leather or fabrics to increase comfort. [0003] The existing coating method is usually to spray the glue on the surface of the interior trim panel before coating to make it composite with the veneer material, and then coat it through a coating machine, such as a compact duplexer disclosed in the prior art 201811318206.3 Although the tw...
