[0022] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] As Figures 1-5As shown in the figure, a hot-melt mold for a steering wheel decoration part includes a workbench 101. Symmetrical bases 102 are connected to the top of the workbench 101 by screws. A fixing frame 103 is connected to the rear end of the top of the workbench 101 by bolts. A positioning mechanism 2 is arranged on the top of the workbench 101. A supporting mechanism 3 is arranged on the top of the base 102. A pressing mechanism 4 is arranged on the fixing frame 103. A fixing mechanism 5 is arranged on the pressing mechanism 4. A limiting mechanism 6 is arranged at the bottom of the supporting mechanism 3. The supporting mechanism 3 includes fixing blocks 301. The fixing blocks 301 are connected to the top of the base 102 by bolts. Symmetrical sliding grooves 302 are opened on the sides of the fixing blocks 301 close to each other. A reset spring 303 is fixedly connected to the bottom of the sliding groove 302. The top of the reset spring 303 is fixedly connected to a supporting plate 304. Auxiliary grooves are opened on the sides of the fixing blocks 301 close to each other. Limiting grooves are opened on the sides of the supporting plate 304 away from each other. As the pressing plate 502 descends, the pressing spring 501 deforms. At the same time, the steering wheel cover drives the supporting plate 304 to descend, causing the reset spring 303 to deform. When the supporting plate 304 descends to contact and squeeze the limiting block 603, causing the limiting spring 602 to deform, then the limiting block 603 slides into the limiting groove on the supporting plate 304, and the limiting spring 602 resumes deformation to limit the supporting plate 304. At this time, the steering wheel logo and the steering wheel cover are assembled and the pressing plate 502 fixes them as a whole, so that the force received by each group of steering wheel logos during assembly is the same, avoiding the appearance of defective products to a certain extent.

[0025] The limiting mechanism 6 includes connecting rods 601. The connecting rods 601 are slidably connected to the bottom of the fixing blocks 301. Limiting blocks 603 are welded to the ends of the connecting rods 601 close to each other. Limiting springs 602 are welded in the auxiliary grooves. The limiting springs 602 are welded to the limiting blocks 603. Remove the completed processed steering wheel cover, and then pull one end of the connecting rod 601 to make the limiting block 603 disengage from the supporting plate 304, so that the reset spring 303 resumes deformation and pushes the supporting plate 304 to reset.

[0026] The pressing mechanism 4 includes a lifting lead screw 402. The lifting lead screw 402 is rotatably connected in the fixing frame 103. A motor 401 is connected to the top of the fixing frame 103 by bolts. The output shaft of the motor 401 is connected to the top of the lifting lead screw 402 by a coupling. A lifting plate 403 is threadedly connected to the lifting lead screw 402.

[0027] The fixing mechanism 5 includes a plurality of pressing springs 501. The pressing springs 501 are welded to the bottom of the lifting plate 403. A pressing plate 502 is welded to the bottom of the pressing springs 501. The steering wheel cover is placed upside down in the arc groove of the supporting plate 304. The supporting plates 304 on both sides limit the steering wheel cover. Then the motor 401 drives the lifting plate 403 to descend, and the pressing plate 502 moves downward to contact and squeeze the steering wheel cover.

[0028] The positioning mechanism 2 includes a positioning ring 201 , which is connected to the top of the workbench 101 by screws. A positioning block 202 is welded to the bottom inner side of the positioning ring 201 .

[0029] The bottom of the lifting plate 403 is connected to a hot melt machine 7 by bolts. The position of the hot melt machine 7 corresponds to the positioning ring 201. The lifting plate 403 is lowered a certain distance to deform the downward pressure spring 501, and the hot melt machine 7 heats up and contacts the positioning column of the steering wheel logo and performs hot melting.

[0030] Working principle: When in use, put the steering wheel with the car logo facing down into the positioning ring 201, and put the steering wheel cover upside down into the arc groove of the supporting plate 304. The supporting plates 304 on both sides limit the steering wheel cover, and then the motor 401 drives the lifting plate 403 to descend, and the pressure plate 502 moves downward to contact and squeeze the steering wheel cover. As the pressure plate 502 descends, the downward pressure spring 501 is deformed, and at the same time, the steering wheel cover drives the supporting plate 304 to descend to deform the return spring 303. When the supporting plate 304 descends to contact and squeeze the limit block 603 to deform the limit spring 602, and then the limit block 603 slides to the limit slot on the supporting plate 304, and the limit The positioning spring 602 recovers its deformation to limit the limit block 603 to the supporting plate 304. At this time, the steering wheel logo and the steering wheel cover are assembled and the pressure plate 502 fixes them as a whole, so that each set of steering wheel logos is subjected to the same force when the assembly is completed, which avoids the occurrence of defective products to a certain extent. Then the lifting plate 403 descends a certain distance to allow the hot melt machine 7 to heat up and contact the positioning column of the steering wheel logo and perform hot melting to form rivet points. Continuous processing avoids errors caused by multiple positioning. Then the motor 401 drives the lifting plate 403 to rise, removes the completed steering wheel cover, and then pulls one end of the connecting rod 601 to separate the limit block 603 from the supporting plate 304.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
