[0002] The inner side of the automobile tailgate is covered with an interior trim panel, which has multiple functions such as hiding the internal mechanical mechanism, filling sound insulation materials, and improving aesthetics; the automobile interior trim panel is usually made of plastic material, and by covering a layer such as a blanket or leather (for high-end models) on its surface, the interior trim panel can have different appearances.

[0003] For example, Chinese Patent CN218535628U, an automatic wrapping tooling for an automobile interior trim panel, includes an automatic wrapping tooling for an automobile interior trim panel. The automatic wrapping tooling for an automobile interior trim panel includes a bottom plate. Support rods are fixedly installed around the bottom plate. A support plate is fixed at the top of the support rods. A cylinder is fixedly installed above the support plate. A hot pressing die is connected below the cylinder. A lower die is fixedly installed above the bottom plate. A film placing mechanism is arranged on the left side of the bottom plate. A wrapping film is arranged inside the film placing mechanism.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0021] In the following description, the "left", "right", "front", "rear", "upper", and "lower" mentioned are oriented in the perspective direction of the front view.

[0022] Embodiment 1: In some embodiments, please refer to the Figures 1 - 3 and Figure 8 of the accompanying drawings of the specification. A continuous injection molded part hot pressing and forming device includes a bottom plate 10 and a top plate 11 fixedly installed at the upper end of the bottom plate 10. A lifting plate 12 is movably arranged up and down at the lower end of the top plate 11, and the lifting plate 12 is driven by a hydraulic cylinder. A upper template 13 is fixedly installed at the lower end of the lifting plate 12, and a cavity for fitting and clamping with the interior trim panel injection molded part is arranged at the bottom of the upper template 13. The upper end of the bottom plate 10 is installed with a lower template 14 through a floating structure. The lower template 14 is used to place the coating film, and the upper template 13 and the lower template 14 cooperate to realize the coating and forming operation of the coating film and the interior trim panel. The floating structure includes guide rods 15, floating springs 16, and positioning blocks 17. Guide rods 15 are fixedly installed at the four corners of the lower end of the lower template 14, and the lower ends of the guide rods 15 are slidably connected with the top plate 11 in a limited way; floating springs 16 are sleeved outside the guide rods 15, and the upper and lower ends of the floating springs 16 are fixedly connected with the lower template 14 and the bottom plate 10 respectively; a number of positioning blocks 17 are fixedly connected with the bottom plate 10 and are located below the lower template 14. The positioning blocks 17 are used to limit the vertical movement of the lower template 14, and a rubber cushion layer for buffering is also arranged at the top of the positioning blocks 17. In the natural state of the floating springs 16, the upper surfaces of the lower template 14 and the side baffle 18 are coplanar. Side baffles 18 are arranged on the four sides of the lower template 14, and the side baffles 18 are fixedly connected with the bottom plate 10. When the upper template 13 and the lower template 14 are closed, there is a space for accommodating the coating part between the side baffles 18 and the injection molded part.

[0023] The uniform edge wrapping mechanism 2 is arranged on the outer sides of the upper template 13 and the lower template 14. The uniform edge wrapping mechanism 2 includes a flip - type side edge wrapping component 21 and an edge wrapping fixing component 22. The flip - type side edge wrapping component 21 is installed on the bottom plate 10 and arranged on the outer side of the lower template 14, and multiple groups of edge wrapping fixing components 22 are arranged on the top plate 11 and located on the outer side of the upper template 13. The flip - type side edge wrapping component 21 is used to make the turned - over surface of the wrapping part abut against the injection - molded part from the side and the top, and the edge wrapping fixing component 22 is used to fix the turned - up edge of the wrapping part on the upper side of the injection - molded part to the injection - molded part. A closed - type heating mechanism 3 is arranged between the upper template 13 and the lower template 14, which is used to heat the injection - molded part and the wrapping part respectively after covering and enclosing them.

[0024] In the present invention, the wrapping part is placed on the lower template 14, and the edge of the wrapping part is supported by the top of the side baffle 18. Then the closed - type heating mechanism 3 is moved between the upper template 13 and the lower template 14. After the closed - type heating mechanism 3 covers and encloses the injection - molded part and the wrapping part respectively, the bonding surfaces of the two are efficiently heated in a nearly closed space, effectively reducing heat loss and shortening the heating time. After heating is completed, the closed - type heating mechanism 3 resets to avoid the upper template 13. The lifting plate 12 moves vertically downward, making the injection - molded part on the upper template 13 gradually approach the wrapping part on the lower template 14. After the upper template 13 and the lower template 14 come into contact, the lifting plate 12 continues to press down. The lower template 14 moves downward through the floating structure, causing the edge of the wrapping part to turn up under the blocking action of the side baffle 18. When the lifting plate 12 stops moving, the flip - type side edge wrapping component 21 outside the lower template 14 approaches the lower template 14 synchronously. First, the turned - up edge of the wrapping part is aligned with the edge of the injection - molded part, and then the wrapping part is gradually closed and bonded to the upper surface of the injection - molded part from the inside to the outside, effectively avoiding the formation of wrinkles on the wrapping part during the wrapping process and improving the product yield. After the edge of the wrapping part is completely closed with the upper surface of the injection - molded part, the edge wrapping fixing component 22 moves downward to hot - press the edge of the wrapping part to fix it tightly to the injection - molded part, realizing the wrapping operation. The lifting plate 12 moves vertically upward, and the finished product part is automatically separated from the upper template 13 under the limiting action of the flip - type side edge wrapping component 21. Then the upper template 13 resets, and the floating structure drives the lower template 14 to lift the finished product part upward to reset, completing the wrapping operation of the interior trim injection - molded part. The entire hot - press wrapping process is carried out continuously and automatically, effectively improving the wrapping efficiency.

[0025] Please refer to Figure 5 and Figure 6 Multiple groups of flip - type side edge wrapping components 21 are arranged on the four sides of the lower template 14, and the flip - type side edge wrapping components 21 on the left and right sides of the lower template 14 are close to the corners of the wrapping part.

[0026] The flip - type side - edge - wrapping component 21 includes a horizontal pushing component, a vertical plate 214, an L - shaped pressing plate 215, and a return spring 216. The horizontal pushing component is installed on the bottom plate 10. A vertical plate 214 is fixedly installed at the moving end of the horizontal pushing component. An L - shaped pressing plate 215 is hinged to the top end of the vertical plate 214. The long side of the L - shaped pressing plate 215 is arranged close to the lower template 14, and the short side of the L - shaped pressing plate 215 is arranged close to the vertical plate 214. A return spring 216 is fixedly installed between the short side of the L - shaped pressing plate 215 and the vertical plate 214. In the natural state of the return spring 216, the long side of the guide rod 15 is inclined upward. The horizontal pushing component includes a support plate 211, a linear guide rail 212, and a first cylinder 213. The support plate 211 is fixedly connected to the bottom plate 10. A linear guide rail 212 and a first cylinder 213 are fixedly installed on the support plate 211. The vertical plate 214 is connected to the linear guide rail 212 in a limited - sliding manner through a slider. The output end of the first cylinder 213 is fixedly connected to the vertical plate 214. The edge - wrapping fixing component 22 includes a hot - pressing plate 221 and a second cylinder 222. The second cylinder 222 is fixedly connected to the upper template 13. The output end of the second cylinder 222 is fixedly installed with a hot - pressing plate 221.

[0027] In the present invention, when the upper template 13 and the lower template 14 are fully closed, the first cylinder 213 drives the vertical plate 214 to approach the injection - molded part under the limiting action of the linear guide rail 212. When the short side of the L - shaped pressing plate 215 aligns the covering part with the opposite side of the injection - molded part, the L - shaped pressing plate 215 flips. The long side of the L - shaped pressing plate 215 gradually closes the covering part from its crease to the edge of the covering part onto the upper surface of the injection - molded part. When the turned - up edge of the covering part is completely adhered to the injection - molded part, the second cylinder 222 drives the hot - pressing plate 221 to move vertically downward, and hot - presses and fixes the edge of the covering part to the injection - molded part to form the workpiece. And in the operation of the flip - type side - edge - wrapping component 21 of this application, first, the flip - type side - edge - wrapping components 21 located on the front and rear sides of the upper template 13 are started, and then the flip - type side - edge - wrapping components 21 located on the left and right sides of the upper template 13 are started, so that the creases at the corners of the injection - molded part are natural and not easily wrinkled.

[0028] Please refer to Figure 4 and Figure 7, the closed heating mechanism 3 includes a bracket 31, a second guide rail 32, a frame 34, a shielding cover 35, a heating device 36 and a horizontal moving and ejecting assembly. Two lower templates 14 are symmetrically arranged on the left and right sides of the upper template 13 and fixedly connected to the bottom plate 10. The upper end of the bracket 31 is fixedly installed with the second guide rail 32, and the frame 34 is limited and slidably connected to the second guide rails 32 on both sides through sliders; shielding covers 35 are arranged at both the upper and lower ends of the frame 34, and the heating device 36 is fixedly installed inside the shielding cover 35. The heating device 36 can be a spotlight or a hot air blower; a horizontal moving and ejecting assembly is arranged between the shielding cover 35 and the frame 34; the frame 34 can be controlled to move forward and backward by a cylinder.

[0029] The horizontal moving and ejecting assembly includes a baffle 33, a fixing pin 37, a tension spring 38 and a hinged plate 39. Hinged plates 39 are symmetrically arranged at the front and rear ends of the side of the shielding cover 35. Both ends of the hinged plate 39 are respectively hinged to the frame 34 and the shielding cover 35 through hinge shafts; the connections between the hinge shafts on the hinged plate 39, the frame 34 and the shielding cover 35 form a parallelogram; the fixing pin 37 is fixedly connected to the frame 34, and a tension spring 38 is installed between the hinge shaft on the shielding cover 35 and the fixing pin 37; in the natural state of the tension spring 38, the frame 34 and the shielding cover 35 are in contact; baffles 33 for blocking the shielding cover 35 from moving forward are symmetrically and fixedly installed at the left and right ends of the bracket 31.

[0030] In the present invention, after the injection molded part and the covering part are in place on the upper template 13 and the lower template 14 respectively, the frame 34 is moved forward under the limiting action of the second guide rail 32. When the shielding cover 35 abuts against the baffle 33, the frame 34 continues to move forward, so that the shielding cover 35 moves outward along the vertical direction relative to the frame 34, and then the shielding covers 35 on the upper and lower sides respectively completely cover the injection molded part and the covering part, forming a nearly closed environment. Subsequently, the heating device 36 is started to heat the two efficiently; after the heating is completed, the frame 34 moves backward for avoidance, and the shielding cover 35 is reset under the action of the tension spring 38 and fits with the frame 34 again.

[0031] Please refer to Figure 5 , a clamping and pre-positioning mechanism 4 is further arranged on the front side of the lower template 14. The clamping and pre-positioning mechanism 4 includes a support seat 41, a rotating shaft 42, a rotating cylinder 43, a connecting plate 44 and a pressing plate 45. The support seat 41 and the rotating cylinder 43 are both fixedly connected to the bottom plate 10. The top end of the support seat 41 is rotatably installed with the rotating shaft 42 through a bearing, and the output end of the rotating cylinder 43 is fixedly connected to the rotating shaft 42; one end of the connecting plate 44 is fixedly connected to the rotating shaft 42, and the other end of the connecting plate 44 is fixedly installed with the pressing plate 45; the pressing plate 45 is used to press the edge of the covering part against the upper end of the side baffle 18, and the contact part between the pressing plate 45 and the covering part is set to be comb-shaped to reduce its blocking effect on the heating device 36.

[0032] Before heating the covering part, the rotating shaft 42 is rotated by the rotating cylinder 43, so that the pressing plate 45 presses and fixes the edge of the covering part on the upper surface of the side baffle 18, avoiding the movement of the covering part during the heating process, enabling the accurate alignment of the covering part and the injection molded part, and improving the accuracy of the hot pressing and covering operation of the injection molded part and the covering part.
