Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0016] See also Figures 1-5 The utility model provides a technical solution: a coating mold for a decorative part in a car tailgate, comprising an upper mold assembly 1, a lower mold assembly 2 and a middle layer heating lamp assembly 3, wherein the upper mold assembly 1 comprises an upper mold base 11 and an upper tire mold 12 installed at the lower side, wherein a vacuum suction cup is embedded in the upper tire mold 12, and the upper tire mold 12 is a convex mold, on which a frame is clamped before pressing and coating ( Figure 2 The upper middle separation part is the skeleton of the decorative part in the tailgate). The lower mold assembly 2 includes a lower mold base 21 and a lower tire mold 22 installed on the upper side thereof. The root of the upper tire mold 12 is movably sleeved with a ring-shaped mounting plate 14. The mounting plate 14 is installed with a plurality of brackets b15 along the edge contour of the upper tire mold 12 on the lower side. The lower end of the bracket b15 is installed with a height-adjustable heating lamp b16. The heating lamp b16 is used to heat the edge of the skeleton of the decorative part. Since the edge contour of the decorative part is an undulating curve, the height of each heating lamp b16 is adjustable to ensure that the vertical distance from the heating part to the heating lamp b16 is consistent, so as to ensure the uniformity of heating. At least two vertical slide cylinders d13 are fixedly installed on the lower side of the upper mold base 11. The piston rod of the slide cylinder d13 pushes the mounting plate 14 to move up and down for adjustment, and all the heating lamps b16 can be raised and lowered synchronously.

[0017] A plurality of slide cylinders c24 arranged along one side of the lower tire mold 22 are installed on the upper side of the lower mold base 21, and a hemming mold c25 is installed on the slider of the slide cylinder c24. A concave mold cavity is provided on the upper part of the lower tire mold 22. The hemming mold c25 is pushed out and pressed on one side of the concave mold cavity. A plurality of two-axis mold groups 23 are installed on the upper side of the lower mold base 21. The two-axis mold groups 23 include a slide cylinder a231, a slide cylinder b233, and a slider of the slide cylinder a231. An L-shaped support 232 is installed on the upper side, and a slide cylinder b233 is vertically installed on the support 232. An edge wrapping die a26 is installed on the output end of the slide cylinder b233 and drives the edge wrapping die a26 to move up and down. An edge wrapping die b27 is fixedly installed on the side of the support 232. The edge wrapping die b27 moves laterally with the support 232. The edge wrapping die a26 is located on the inner side of the edge wrapping die a26. The edge wrapping die a26 and the edge wrapping die b27 are located on the other side of the concave mold cavity. Figure 5 As shown, the hemming mold a26 and the hemming mold b27 are used to wrap the fabric on the side with the folded edge on the frame.

[0018] The lower die base 21 is rectangular and vertical columns are fixedly installed at the four corners of the upper side respectively. Vertical buffers are fixedly installed at the four corners of the lower side of the upper die base 11, and the lower ends of the buffers are butted against the columns one by one. The heating lamp tube assembly 3 includes two horizontal and parallel cross beams 31. The cross beams 31 are installed on the outer sides of the columns. Linear guides are installed on the upper sides of the cross beams 31. A slidable transfer seat 33 is installed between the two linear guides. Height-adjustable heating lamp tubes a35 are installed on the upper side of the transfer seat 33 through brackets a34 respectively. A transfer cylinder 32 is installed on the side of the cross beam 31. The transfer cylinder 32 pushes the transfer seat 33 to move horizontally. The transfer seat 33 moves between the upper die assembly 1 and the lower die assembly 2 before pressing to heat the skeleton and the fabric to improve the bonding viscosity.

[0019] Working principle: When in use, this mold is installed in a press. Before pressing, the skeleton is adsorbed and clamped on the upper mold 12. After the fabric is coated with glue, it is placed on the lower mold 22 and fixed by hanging pins. The upper mold 12 and the lower mold 22 are both designed according to the shape of the skeleton. The transfer cylinder 32 moves the heating lamp tube a35 to the working position. The slide table cylinder d13 pushes the mounting plate 14 downward so that the heating lamp tube b16 is close to the edge of the skeleton. After being powered on and turned on, the heating lamp tube a35 and the heating lamp tube b16 heat the skeleton and the fabric. After heating is completed and they return to their positions, the upper die assembly 1 and the lower die assembly 2 are closed and pressed so that the fabric is bonded to the skeleton. The two-axis module 23 drives the edge wrapping molds a26 and b27 to act, and the slide table cylinder c24 drives the edge wrapping mold c25 to act so that the fabric is edge-wrapped at the edge of the skeleton. After pressure holding, the edge wrapping assembly returns to its position, and then the mold is opened to take out the workpiece.

[0020] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
