The second wedge-shaped push rod 53 is provided with a push column 54 on the side of the second wedge-shaped push rod 53 facing the power supply 6; wherein the lower end of the first wedge-shaped push rod 51 is inserted into the inside of the second slide groove 41 and is slidably connected with the second slide groove 41, the second wedge-shaped push rod 53 is placed in the inside of the third slide groove 42, the lower end of the upper base 3 is provided with a first slide groove 31, and the first sliding seat 52 is slidably connected to the first slide groove 31; the driving member 5 also includes a push block 55 located on the side of the second wedge-shaped push rod 53 facing away from the push column 54 and placed on the side of the switch key 43; the power supply 6 ... The main power switch 61 in the No. 3 slide 42 and electrically connected to the switch key 43, the exhaust member 62 slidably connected to the main power switch 61 and used to stop the main power switch 61 from supplying power to the cooling component 7; the exhaust member 62 includes an air duct 621 communicating with the interior of the lower base 11, a telescopic block 622 located on the air duct 621 and with the lower end extending into the air duct 621, a driving rod 623 located at the upper end of the telescopic block 622 and extending into the No. 3 slide 42, and a driving rod 623 movably connected to the driving rod 623 through a rotating shaft and connected to the main power switch 61. The No. 2 sliding seat 624 is slidably connected; wherein the telescopic block 622 is made of an expansion material that expands with heat and contracts with cold. The No. 1 wedge-shaped push rod 51 slides along the No. 2 slide groove 41 during the descent process, thereby realizing the guiding operation during the mold stamping process, avoiding the dislocation during the mold stamping process, and ensuring the smooth progress of the stamping process. The No. 2 wedge-shaped push rod 53 in the driving member 5 is reset by its own gravity during the process of separating from the No. 1 wedge-shaped push rod 51.

[0033] It should be noted that the present invention is a cooling device for a hot forming mold for an automobile cross beam. When the hot forming mold for the automobile cross beam needs to be used, the upper mold 10 and the lower mold 12 are first preheated by using the heating wire 13, and then the heated automobile cross beam plate is placed on the lower mold 12, and then the hydraulic cylinder 2 is driven to work and the heating wire 13 is turned off. The hydraulic cylinder 2 drives the upper base 3 and the upper base 9 on the push column 8 to descend synchronously, so that the upper mold 10 on the upper base 9 is pressed down onto the lower mold 12, so that the automobile cross beam plate is stamped and formed. During the pressing process, the No. 1 wedge-shaped push rod 51 connected to the upper base 3 through the No. 1 sliding seat 52 descends along the No. 2 slide groove 41. When the upper mold 10 and the lower mold 12 are completed to be molded, the No. 1 wedge-shaped push rod 51 extending into the No. 2 chute 41 drives the No. 2 wedge-shaped push rod 53 to move along the No. 3 chute 42, so that the push column 54 on the No. 2 wedge-shaped push rod 53 presses the power supply master control switch 61 to realize the power-on operation of the cooling component 7 and the switch key 43. When the upper mold 10 and the lower mold 12 are completed to be molded, the No. 1 wedge-shaped push rod 51 rises along the No. 2 chute 41, so that the No. 2 wedge-shaped push rod 53 in the No. 3 chute 42 moves along the No. 3 chute 42 under the action of its own gravity, so that the push block 55 on the No. 2 wedge-shaped push rod 53 contacts the switch key 43 in the lower base 4, thereby realizing the The fan 71 is started up and blows air to the inside and outside of the upper mold 10 and the lower mold 12 through the main pipe 72, the nozzle 74 and the branch pipe 75 to cool down the upper mold 10 and the lower mold 12 continuously, thereby achieving a full range of cooling operations. The heated gas that has completed the heat exchange in the lower base 11 is transported to the outside through the air guide pipe 621 for discharge. During the process of discharging the gas, the telescopic block 622 detects the gas temperature. As the temperature of the discharged gas in the air guide pipe 621 continues to decrease, the telescopic block 622 contracts, thereby driving the driving rod 623 to descend and causing the second sliding seat 624 to slide along the main power control switch 61 under the action of the driving rod 623, and driving the main power control switch 61 to be pressed again. , realizing the overall power-off operation of the switch key 43 and the cooling component 7, and finally completing the automatic opening and closing operation of the cooling component 7, without the need for manual opening by the operator. In the process of the driving component 5 driving the power supply component 6, the No. 1 wedge-shaped push rod 51 slides along the No. 2 slide groove 41 during the descent, thereby realizing the guiding operation during the mold stamping process, avoiding misalignment during the mold stamping process, and ensuring the smooth progress of the stamping process. The No. 2 wedge-shaped push rod 53 in the driving component 5 is reset by its own gravity during the process of separating from the No. 1 wedge-shaped push rod 51. Compared with the traditional spring reset structure, it avoids the elastic fatigue caused by the spring reset, which is beneficial to prolonging the service life of the equipment.
