[0027] In the utility model, two trim panel molding cavities 3 are symmetrically arranged between the upper template 1 and the lower template 2, which can be injection molded to adapt to the left trim panel and the right trim panel of the electric vehicle at one time, which can effectively reduce the number of molds for producing the trim panels required for an electric vehicle, thereby reducing production costs. Secondly, the multi-point glue feeding mechanism 5 can improve the injection molding efficiency. The multi-point glue feeding mechanism 5 is connected to the bottom of the buckle plate molding part 4 through the bottom glue feeding channel structure 6, so that the glue port can be formed at the bottom of the buckle plate molding part 4, thereby being able to minimize the influence of the glue port on the quality of the product's outer surface.

[0028] Specifically, the multi-point glue feeding mechanism 5 includes an injection molding plate 7, and a plurality of vertically arranged injection molding tubes 8 are fixedly connected to the bottom of the injection molding plate 7, and the ends of the injection molding tubes 8 are connected to a bottom glue feeding channel structure 6 arranged on the upper surface of the lower mold plate 2, and the glue outlet of the bottom glue feeding channel structure 6 is connected to the bottom of the gusset plate forming part 4. The injection molding plate can divert the injection liquid and feed the glue into the molding cavity of the decorative plate through a plurality of injection molding tubes at the same time, and the glue outlet of the bottom glue feeding channel structure 6 is connected to the bottom of the gusset plate forming part 4, so that the glue outlet can be formed at the bottom of the gusset plate forming part 4, thereby being able to minimize the influence of the glue outlet on the quality of the outer surface of the product.

[0029] Preferably, the injection tube 8 is arranged on the periphery of the decorative plate molding cavity 3 and a plurality of injection tubes 8 are arranged circumferentially along the decorative plate molding cavity 3, so that when the glue liquid is injected into the decorative plate molding cavity, it can be injected from the outside to the inside from multiple directions, which can improve the injection efficiency.

[0030] Specifically, the bottom glue inlet channel structure 6 includes a glue inlet groove 10 connected to the bottom end of the injection tube 8, and the side of the glue inlet groove 10 is provided with a No. 1 flow channel 11 extending to the side of the decorative plate molding cavity 3, and the side of the No. 1 flow channel 11 close to the decorative plate molding cavity 3 is provided with a bottom glue inlet flow channel 12, the bottom glue inlet flow channel 12 is inclined and the glue outlet is located at the top of the bottom glue inlet flow channel 12, the inner diameter of the glue inlet groove 10 is larger than the outer diameter of the bottom end of the injection tube 8, and the No. 1 flow channel 11 is far away from the glue inlet groove 10 and is parallel to the side of the buckle plate molding part 4 close to the No. 1 flow channel 11.

[0031] After flowing out from the bottom end of the injection tube, the glue liquid can enter the glue inlet groove, and then flow into the bottom glue inlet channel through the No. 1 flow channel, and finally enter the decorative panel molding cavity from the bottom of the buckle plate molding part 4 through the glue inlet at the top of the bottom glue inlet channel, so that the glue port can be formed at the bottom of the buckle plate.

[0032] Specifically, a top plate 13 is further provided on the lower side of the lower mold plate 2, and a combined ejection mechanism connected to the decorative plate forming cavity 3 is provided on the top plate 13, and the combined ejection mechanism includes an edge ejection assembly 14 and a middle ejection assembly 15. When the top plate moves upward, the edge ejection assembly 14 and the middle ejection assembly 15 can respectively apply thrust to the decorative plate product at the edge position and the middle position of the decorative plate, so that the force at each position of the decorative plate is more uniform when ejecting.

[0033] Specifically, the edge ejection assembly 14 includes a plurality of outer inclined ejector blocks 16 arranged along the outer edge of the trim molding cavity 3. The top of the outer inclined ejector block 16 is connected to the gusset molding part 4, and the bottom of the outer inclined ejector block 16 is hinged to the top plate 13 through an inclined ejector rod. When the top plate moves upward, the outer inclined ejector block can be driven by the inclined ejector rod to apply a thrust to the edge of the product. The top of the outer inclined ejector block 16 is connected to the gusset molding part 4 so that the thrust of the trim product acts on the bottom of the gusset to prevent the trim from being damaged during ejection.

[0035] Specifically, the side of the lower mold plate 2 is also provided with a side core pulling mechanism, which includes a core pulling slider 18, the inner end of which is fixedly connected to a side core block 19 inserted into the molding cavity 3 of the decorative plate, and the upper mold plate 1 is also fixedly connected to an inclined driving rod 20, which is obliquely inserted into the core pulling slider 18 and slidably cooperates with the core pulling slider 18. When the mold is opened, the upward movement of the upper mold plate can drive the driving rod to move vertically upward, and the vertical upward movement of the driving rod can drive the core pulling slider to move away from the molding cavity so that the side core block can be separated from the product.

[0036] The working principle of the utility model is as follows: two trim plate forming cavities 3 are symmetrically arranged between the upper template 1 and the lower template 2, which can be used for one-time injection molding of the left trim plate and the right trim plate adapted to the electric vehicle, which can effectively reduce the number of molds for producing trim plates required for an electric vehicle, thereby reducing production costs. Secondly, the multi-point glue feeding mechanism 5 can improve the injection molding efficiency. The multi-point glue feeding mechanism 5 is connected to the bottom of the gusset plate forming part 4 through the bottom glue feeding flow channel structure 6, so that the glue port can be formed at the bottom of the gusset plate forming part 4, thereby being able to minimize the influence of the glue port on the quality of the product outer surface.

[0037] The injection molding plate can split the injection liquid and inject glue into the decorative plate molding cavity through several injection molding tubes at the same time. The glue outlet of the bottom glue inlet flow channel structure 6 is connected with the bottom of the gusset plate molding part 4, so that the glue outlet can be formed at the bottom of the gusset plate molding part 4, thereby minimizing the influence of the glue outlet on the quality of the product outer surface. After the glue flows out from the bottom end of the injection molding tube, it can enter the glue inlet groove, and then flow into the bottom glue inlet flow channel through the No. 1 flow channel, and finally enter the decorative plate molding cavity from the bottom of the gusset plate molding part 4 through the glue inlet at the top of the bottom glue inlet flow channel, thereby enabling the glue outlet to be formed at the bottom of the gusset plate;

[0038] When the top plate moves upward, the edge ejection assembly 14 and the middle ejection assembly 15 can respectively apply thrust to the edge position and the middle position of the decorative plate to the decorative plate product, so that the force at each position of the decorative plate during ejection is more uniform. When the top plate moves upward, the outer inclined ejector block can be driven by the inclined ejector rod to apply thrust to the edge of the product. The top of the outer inclined ejector block 16 is connected to the gusset plate forming part 4, so that the thrust received by the decorative plate product acts on the bottom of the gusset plate to prevent the decorative plate from being damaged during ejection. When the top plate moves upward, the inner inclined ejector block can be driven by the inclined ejector rod to apply thrust to the middle position of the product, so that the force at each position of the product can be more uniform.

[0039] When the mold is opened, the upper mold plate moves upward to drive the driving rod to move vertically upward, and the driving rod moves vertically upward to drive the core-pulling slider to move away from the molding cavity so that the side core block can be separated from the product.
