Embodiment Construction

[0019] Such as figure 2 As shown, the composite tooling of the present invention includes a frame 1, an upper mold 2, and a lower mold 3. The upper mold 2 is installed on the frame 1 through a lifting device 4, and the lower mold 3 is directly installed on the frame 1. Between the upper mold 2 and the lower mold 3, a radiation heating device 7 that can enter and exit the frame is also provided, and the lower mold 3 is also provided with a cooling water pipe 8, which can be connected to cooling water.

[0020] In the fabric compounding process of the Great Wall CH071 spare tire cover, the surface material 6 sprayed with hot melt adhesive is prepared first, and the surface material 6 is laid on the lower mold 3 of the tooling, and the base plate 5 is installed on the upper mold 2 . The radiation heating device 7 enters between the upper and lower molds, heats the surface material 6 on the lower mold 3, softens and melts the hot melt adhesive, and then withdraws the radiation he...

Abstract

The invention relates to a spare tire cover plate production method and a composite tool. In the production process, a base plate is arranged on an upper die, a facing material is paved on a lower die, an extractable radiation heating plate is adopted to heat glue on the facing material to solve the problems of easy cooling and hand sticking caused by preheating of the facing material in the prior art, and the lower die is introduced with cooling water to solve the tackless problem caused by untimely cooling and low initial viscosity after compounding completed through a lower die heating scheme in the prior art.

Description

technical field [0001] The invention relates to a production method of a spare tire cover plate and composite tooling, in particular to a method for compounding surface decoration materials of a spare tire cover plate and a composite tooling with a heating function. Background technique [0002] The spare tire cover is an automotive interior part, including a substrate and a surface material covering the substrate, and the two are glued together. The lamination of facing materials and substrates is an important step in the production process. In order to realize the precise positioning of the two, composite tooling is generally used to realize the positioning and compounding of the substrate and the surface material. [0003] Existing tooling such as figure 1 As shown, it includes a frame 1, an upper mold 2, and a lower mold 3. The upper mold 2 is installed on the frame 1 through a lifting device 4, and the lower mold 3 is directly installed on the frame 1. The substrate ...
