Description

Technical Field

[0001] The utility model relates to the technical field of automobile component coating, in particular to a coating device for automobile injection molding parts. Background Art

[0002] Cars are ubiquitous in our daily lives. In addition to important components such as the frame and drive unit, cars also need to be equipped with interior panels. Interior panels are mostly composed of injection molded parts and coating films, which can play a decorative role in the car. Interior panels can not only beautify the interior space, but also have a certain protective effect on the interior and body of the car. At present, after the injection molding of the interior panels is formed, it is necessary to use a coating machine to coat its surface according to actual needs. After the coating is completed, the coating machine needs to manually remove the interior panels from the bottom mold. Since the coating of the interior panels adopts a hot pressing process, this method of taking is likely to cause damage to the hands of the staff, and thus there are certain safety hazards. To this end, we provide a coating device for automotive injection moldings to solve the above problems. Utility Model Content

A bottom mold 4 is fixedly installed at the top opening of the base 1, and the bottom mold 4 is fixed to the top of the opening of the base 1 by bolts. A hydraulic cylinder 5 is fixedly installed inside the top plate 3 in a through-type manner, and a top mold 6 is fixedly installed at the movable end of the hydraulic cylinder 5. The top mold 6 is correspondingly arranged with the bottom mold 4. The correspondingly arranged bottom mold 4 and top mold 6 can be correspondingly pressed under the action of the hydraulic cylinder 5. After pressing, the injection molded part and the coating film are bonded together to form an interior trim panel. The base 1 A cylinder 7 is fixedly installed at the bottom of the inner cavity, and a connecting plate 8 is fixedly installed at the movable end of the cylinder 7. Support rods 9 are fixedly installed on both sides of the top of the connecting plate 8. Through grooves 10 are opened on both sides of the interior of the bottom mold 4. Two support rods 9 are respectively inserted into the inner cavity of the two through grooves 10. A tightly fitting sliding connection design is adopted between the support rods 9 and the through grooves 10, thereby avoiding wrinkles in the coating film. By opening a through groove 10 at the bottom of the bottom mold 4 and using the cylinder 7 and the connecting plate 8 to push the support rod 9 to move, the moving support rod 9 can drive the interior panel to separate from the bottom mold 4. After the interior panel is separated from the bottom mold 4, the staff can remove the interior panel after wearing gloves, so that the entire retrieval process does not contact the bottom mold 4, thereby ensuring the safety of retrieval.

[0013] Specifically, the connecting plate 8 is designed in a "J" shape, and its design purpose is to facilitate the installation of the cylinder 7, thereby further controlling the volume of the base 1. Two sliding rods 11 are arranged in parallel on both sides of the inner cavity of the base 1. The outer wall of the sliding rod 11 is slidably connected with a sliding sleeve 12.
