[0033] Please refer to Figures 1 to 4 The utility model provides a car sunroof bracket mold, including two mold bases 1, the two mold bases 1 are divided into an upper mold base 11 and a lower mold base 12 distributed relatively in the upper and lower directions, and an annular cavity 13 adapted to the sunroof bracket is formed between the upper mold base 11 and the lower mold base 12. A heat dissipation channel 14 is formed in each mold base 1, and the heat dissipation channel 14 is arranged around the inner ring and the outer ring of the annular cavity 13.

[0034] Both the upper die base 11 and the lower die base 12 are equipped with heat dissipation channels 14, which are arranged around the inner and outer rings of the annular cavity 13. Cooling fluid flows directly through the interiors of the two die bases 1 through these heat dissipation channels 14, removing heat from the annular cavity 13. This effectively reduces the temperature of the contact surface between the molten material and the annular cavity 13, ensuring a uniform temperature of the molten material within the annular cavity 13. This improves product quality and the heat dissipation performance of the mold, reduces thermal stress, and extends the mold's service life.

[0035] Specifically, each mold base 1 is spliced together by multiple modules 15, each module 15 forms a cavity section 131, and multiple cavity sections 131 constitute the annular cavity 13; the heat dissipation channel 14 includes multiple branch channels 141, and multiple branch channels 141 are formed one by one in multiple modules 15, and each branch channel 141 surrounds the periphery of the cavity section 131 of the corresponding module 15.

[0036] In this embodiment, continue to refer to Figures 1 to 4 Each of the modules 15 has a branch channel 141, and each of the branch channels 141 surrounds the periphery of the cavity section 131 of the corresponding module 15, so that each of the branch channels 141 can simultaneously circulate cooling fluid to cool the molten material, thereby ensuring uniform cooling of the annular cavity 13, reducing the flow distance and time of the cooling fluid, and improving the cooling efficiency.

[0037] It should be noted that the present invention does not limit the number of the modules 15. Specifically, in this embodiment, each mold base 1 is composed of eight modules 15, and the eight modules 15 are divided into: two first modules 151, two second modules 152, and four third modules 153. The two first modules 151 extend in the transverse direction and are spaced apart in the longitudinal direction. The two second modules 152 extend in the longitudinal direction and are spaced apart in the transverse direction. The third modules 153 abut against the two ends of the first modules 151 and the second modules 152.

[0038] In this embodiment, referring to Figure 1 and Figure 3 The modules 15 are arranged in eight pieces, which can ensure uniform and rapid cooling while being easy to manufacture. The multiple modules 15 of the upper die base 11 are arranged in a one-to-one correspondence with the multiple modules 15 of the lower die base 12.

[0039] Specifically, the inlet and outlet of each branch channel 141 are located on the side of the corresponding module 15 facing away from the cavity section 131 in the upper and lower directions, thereby facilitating the arrangement of the branch channels and the entry and exit of the cooling fluid in each branch channel 141.

[0040] In order to inject glue into the annular cavity 13, in this embodiment, refer to Figures 1 to 3 The automobile sunroof bracket mold also includes a glue injection line 2, which includes a glue injection pipe 21, a main line 22, and multiple branch pipes 23. The glue injection pipe 21 extends in an upward and downward direction, and its upper end is used for plastic to enter; the main line 22 extends in the longitudinal direction, and the middle part of the main line 22 is connected to the lower end of the glue injection pipe 21; the multiple branch pipes 23 are set to the same length, and one end of the multiple branch pipes 23 is connected to the main line 22, and the other end is connected to the annular cavity 13. The molten material is injected from the glue injection pipe 21 into the main line 22, and then injected into the annular cavity 13 through the multiple branch pipes 23. This ensures that the molten material enters the annular cavity 13 evenly, avoids uneven pressure of the molten material injected into the annular cavity 13, and improves product dimensional accuracy and product quality.

[0041] Specifically, refer to Figures 2 to 4In this embodiment, the plurality of branch pipes 23 are divided into four first branch pipes 231 extending in the longitudinal direction and two second branch pipes 232 extending in the transverse direction; wherein, every two first branch pipes 231 and one second branch pipe 232 are connected to one end of the main line 22. In this embodiment, every two first branch pipes 231 are connected to both ends of the cavity section 131 of one first module 151. Each second branch pipe 232 is connected to the middle of the cavity section 131 of each second module 152. This ensures uniform entry of the molten material while ensuring uniform cooling, with good coordination effect, ensuring uniform pressure and temperature of the injected molten material, ensuring product quality and production efficiency, and making the mold evenly stressed during processing, reducing deformation and wear of the mold, and improving mold stability.

[0042] In this embodiment, the upper and lower tube walls of the plurality of branch tubes 23 connected to the ends of the annular cavity 13 are gradually approached in the direction approaching the annular cavity 13 to buffer the speed of the molten material entering the annular cavity 13 .

[0043] To further dissipate heat, in this embodiment, the wall of the annular cavity 13 is covered with a heat dissipation film. The heat dissipation film can be a high-efficiency heat dissipation material coating or a heat sink. This reduces the thermal stress of the mold and extends its service life.

[0044] In addition, refer to Figure 1 、 Figure 3 and Figure 5 In this embodiment, the automobile sunroof mold further includes an upper die 31 and a lower die 32, with the upper die base 11 and the lower die base 12 positioned between the upper die 31 and the lower die 32. Both the upper die 31 and the lower die 32 are provided with an inlet channel 33 communicating with each inlet, and an outflow channel 34 communicating with each outlet. In this embodiment, each inflow channel 33 and each outflow channel 34 extend longitudinally. The longitudinal direction corresponds to the width of the die base 1. This reduces the length of each inflow channel 33 and each outflow channel 34, simplifying manufacturing.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
