[0012] Compared with the prior art, this multi-temperature zone dynamic heating blister mold for automotive parts has the following advantages:

[0013] Beneficial effects:

[0014] 1. The utility model is fixedly connected with a lifting assembly on both sides of the device frame, and the clamping assembly is fixed to one side of the telescopic end of the lifting assembly. Before using the device, the thermoplastic plate is placed on the fault in the middle of the slide slot, and the clamping cylinder is operated through the device panel.
