[0053] The specific operation mode of the present invention is as follows:

[0054] First, the plastic plate is placed on the heater to be baked until softened, and then placed on the placement frame 20 for fixing, and then the driving motor 53 is started to make the nut seat 52 drive the lifting plate 60 to rise, so that the lifting plate 60 contacts the placement frame 20, and at the same time, the mold plate 70 on the lifting plate 60 contacts the plastic plate, and the plastic plate is initially covered on the mold plate 70, and then the air pump 30 is operated to suck air through the suction pipe 40, and the air between the plastic plate and the mold plate 70 can be extracted through the suction hole 73 through the connection between the first air hole 62 and the second air hole 72 and the suction pipe 40, so that the plastic plate is attached to the mold plate 70, and after waiting for cooling, the driving motor 53 is operated again to lower the lifting plate 60, and finally the thermoformed automobile parts are removed;

[0055] When different types of automotive parts need to be thermoformed, the tool only needs to be used to push the shift block 82 outward to retract the positioning button 81 from the mounting groove 61, and then the mold plate 70 can be taken out upward, and then the mold plate 70 to be used can be inserted into the mounting groove 61, and the shift block 82 is released. The positioning button 81 is pushed back by the force of the compression spring 83, and is inserted into the positioning groove 71 to complete the fixation of the lifting plate 60 and the mold plate 70, and the mold plate 70 can be replaced.

[0056] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method.
