[0035] When the embodiment of the present application is in use, first, the upper connecting seat 29 and the lower connecting seat 26 are respectively bolted and arranged at the bottom end of the upper bearing seat 28 and the top end of the lower bearing seat 25. A guide rod 30 and a guide cylinder 27 are respectively arranged at the bottom end of the upper connecting seat 29 and the top end of the lower connecting seat 26. When the upper template 18 moves downward, the lower end of the guide rod 30 will be inserted into the guide cylinder 27 to limit the downward movement range of the upper template 18 and reduce the phenomenon of deviation during the downward movement of the upper template 18. Then, through the arrangement of the pin column 24 and the pin hole 23, when the upper die 22 moves downward to the top end of the lower die 21, the lower end of the pin column 24 will be inserted into the interior of the pin hole 23, so that the upper die 22 can be accurately pressed against the top end of the lower die 21 to perform die casting on the rearview mirror bracket. Since the rearview mirror bracket cavities are provided at the top of the lower die 21 and the bottom of the upper die 22, when the upper die 22 is pressed against the top end of the lower die 21, the two cavities will form a complete rearview mirror bracket cavity. Just inject the hot melt raw material into the cavity through the pouring port opened on the outer wall of the upper die 22, and then the die casting operation of the rearview mirror bracket can be completed. After that, the coolant is injected and stored in the liquid storage tank 2. Then, the first water pump 7, through the first liquid delivery pipe 8 and the second liquid delivery pipe 9, conveys the coolant inside the liquid storage tank 2 to the first liquid passage pipe 10, and the coolant inside the first liquid passage pipe 10 flows into the cooling tank 4 through the third liquid delivery pipe 11. During this process, the coolant inside the cooling tank 4 releases a low-temperature medium to cool down the heat conduction plate 5. Since the lower template 17, the lower die base 19 and the lower die 21 are all made of metal materials with good heat conduction performance, the heat conduction plate 5 can transfer the low temperature to the rearview mirror bracket inside the lower die 21 through the lower template 17 and the lower die base 19 to cool down the die-cast rearview mirror bracket and improve the die casting efficiency of the rearview mirror bracket. Finally, the second water pump 13 sucks and conveys the coolant inside the cooling tank 4 through the first drain pipe 14, the second liquid passage pipe 15 and the second drain pipe 16 to drain the coolant inside the cooling tank 4 back into the liquid storage tank 2, so as to circulate and convey the coolant inside the cooling tank 4 and ensure that the coolant inside the cooling tank 4 is in a low-temperature state, thus completing the use of the die casting mold.
