DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-6 The utility model provides a technical solution: a covering mold for a C-pillar decorative part of an automobile, comprising an upper mold assembly 1, a lower mold assembly 2 and a heating assembly 3. The upper mold assembly 1 and the lower mold assembly 2 are provided with buffer cylinders at four opposite corners. The upper mold assembly 1 comprises an upper mold plate 11 and an upper module 12. A concave mold cavity is provided at the lower part of the upper module 12. The concave mold cavity is a cavity designed according to the shape of the C-pillar decorative part. An embedded vacuum suction cup is installed in the concave mold cavity. The vacuum suction cup is used to absorb and fix the skeleton before mold closing. A plurality of columns 14 are fixedly installed on the lower side of the upper mold plate 11. The side of the upper module 12 is connected to the column 14 through a slide rail 15. A vertical cylinder a16 is installed on the lower side of the upper mold plate 11. The cylinder a16 is used to push the upper module 12 up and down. A pillar 13 is provided on the lower side of the upper mold plate 11. The pillar 13 is used to press and limit the back of the upper module 12.

[0020] The lower mold assembly 2 includes a lower mold plate 21 and a lower module 22. The edge of the lower module 22 is provided with a plurality of matching edge molds 23. The edge molds 23 are strip-shaped and driven by a cylinder b24 or a two-axis module 25. The two-axis module 25 includes a slide cylinder a251 and a slide cylinder b252. The slide cylinder b252 is installed on the slider of the slide cylinder a251. The slider of the slide cylinder b252 is installed with a corresponding edge mold 23, and the edge mold 23 can move in two linear dimensions. The two-axis module 25 is mainly used for the corners of the covering mold. The edge of the lower module 22 is provided with a plurality of vertical through holes, and hanging pins are inserted in the through holes. The hanging pins are correspondingly driven to extend and retract by the cylinder c26 installed on the lower mold plate 21, and the hanging pins are used to hang the covered leather.

[0021] The heating component 3 includes a mounting frame 31 installed on the side of the buffer cylinder, a moving seat 33 is installed on the upper side of the mounting frame 31 through a linear guide rail, a rodless cylinder 32 is installed on the side of the mounting frame 31, the rodless cylinder 32 drives the moving seat 33 to move horizontally, a carrier plate 34 is provided on the moving seat 33, and a plurality of heating lamp tube assemblies 35 are installed on the carrier plate 34. Before mold closing, the lamp tube assembly 35 is powered on, and the moving seat 33 moves it between the upper mold assembly 1 and the lower mold assembly 2 to heat the skeleton and the surface material, which is beneficial to improve the bonding effect.

[0022] The lamp assembly 35 includes an infrared lamp tube 351 and two L-shaped brackets 352. The brackets 352 are provided with vertical long holes 353. The two ends of the infrared lamp tube 351 are respectively installed with tube brackets 354. The tube brackets 354 and the long holes 353 are locked in position by bolts. Since the surface of the decorative plate is not flat and has undulating curvatures, in order to keep the distance between each infrared lamp tube 351 and the decorative plate uniform, the height of the infrared lamp tube 351 on the bracket 352 is designed to be adjustable.

[0023] Working principle: When in use, this mold is installed in a press machine, and the skeleton is manually placed in the upper module 12. The cylinder c26 pushes the hanging pin to extend, and the surface material coated with glue is placed in the lower module 22. Before closing the mold, the moving seat 33 and the lamp tube assembly 35 enter between the upper mold assembly 1 and the lower mold assembly 2 to heat the leather material and the skeleton. After the lamp tube 35 is moved out, the mold is closed, and the cylinder c26 pulls the hanging pin 27 back, and then the edge wrapping mold 24 is actuated to wrap the edge. After maintaining the pressure for a certain period of time, the mold is separated and the coated interior parts are taken out.
