The top end of the first foldable infusion tube 62 is connected to the top plate 30, and the bottom end of the second foldable infusion tube 63 is connected to the base 10.

[0039] In this embodiment, the coolant is stored by the first foldable infusion tube 62, the second foldable infusion tube 63 and the liquid replacement assembly 61. The first foldable infusion tube 62 and the second foldable infusion tube 63 can follow the upper mold 43 that can be raised and lowered by the folding function of the first foldable infusion tube 62 and the second foldable infusion tube 63.

[0040] Optional, such as Figure 1 and Figure 2 As shown, the ends of the first foldable infusion tube 62 and the second foldable infusion tube 63 that are away from each other are both connected with a hollow connector 64, the hollow connector 64 is connected with the inner cavities of the tube bodies of the first foldable infusion tube 62 and the second foldable infusion tube 63, the first foldable infusion tube 62 is connected to the lower surface of the top plate 30 through the hollow connector 64, and the second foldable infusion tube 63 is connected to the upper surface of the base 10 through the hollow connector 64.

[0041] In this embodiment, by setting a hollow connecting head 64, the first foldable infusion tube 62 is connected to the lower surface of the top plate 30, and the second foldable infusion tube 63 is connected to the upper surface of the base 10, thereby completing the installation of the first foldable infusion tube 62 and the second foldable infusion tube 63.

[0042] Optional, such as Figure 1 and Figure 2 As shown, the two hollow connectors 64 at the same end are connected via a connecting pipe 641 , and a heat-insulating cover 642 is provided on the outside of the connecting pipe 641 .

[0043] In this embodiment, the two hollow connectors 64 are connected by a connecting tube 641 so that when the first folding infusion tube 62 or the second folding infusion tube 63 is squeezed, the connecting tube 641 can transport the cooling liquid in the tube body.

[0051] Based on the same inventive concept, this embodiment also provides a method for hot forming an automobile part, comprising the following steps.

[0052] Step 1: The upper mold sleeve 42 is driven down by the oil cylinder 41, so that the upper mold 43 and the lower mold 50 are merged by the lifting and lowering of the upper mold sleeve 42.

[0053] Step 2: The raw material in the mold is thermoformed by combining the upper mold 43 and the lower mold 50 to obtain a thermoformed automobile part;

[0054] Step three, the upper mold sleeve 42 rises, the upper mold 43 and the lower mold 50 are separated, and the coolant in the mold temperature adjustment mechanism 60 enters the upper mold 43 and the lower mold 50 for heat dissipation.

[0055] Furthermore, in step three, the upper mold sleeve 42 rises, and the coolant in the mold temperature adjustment mechanism 60 enters the upper mold 43 and the lower mold 50 for heat dissipation. Specifically, the following steps are included: during the rising process of the upper mold 43, the coolant in the first folded liquid infusion tube 62 is squeezed by the upper mold 43, so that the coolant in the first folded liquid infusion tube 62 passes through the connecting tube 641, the hollow connecting head 64 at the bottom and the liquid delivery tube 631 in sequence, and enters the heat dissipation flow channel 431 of the upper mold 43 and the lower mold 50, so that the coolant is used to dissipate heat for the separated upper mold 43 and the lower mold 50.

[0056] The specific operation mode of the present invention is as follows:

[0057] When the hot forming device for automobile parts is used, the upper die sleeve 42 is driven down by the oil cylinder 41, and the upper die sleeve 42 is raised and lowered to drive the upper die 43 and the lower die 50 to be combined, so as to perform hot forming processing on the raw materials in the die.

[0058] During the rising process of the upper mold 43, the coolant in the first folded infusion tube 62 is squeezed by the upper mold 43, so that the coolant in the first folded infusion tube 62 passes through the connecting tube 641, the hollow connecting head 64 at the bottom and the liquid delivery tube 631 in sequence, and enters the heat dissipation channel 431 of the upper mold 43 and the lower mold 50, thereby dissipating heat for the separated upper mold 43 and the lower mold 50 through the coolant.

[0059] During the downward pressing of the upper mold 43, the second folded infusion tube 63 is squeezed by the upper mold 43, so that the liquid in the second folded infusion tube 63 is squeezed into the heat dissipation channel 431 of the upper mold 43 and the lower mold 50 at the same time, and the coolant in the heat dissipation channel 431 that has undergone heat exchange is squeezed out, thereby facilitating the cooling of this part of the coolant through the heat dissipation fan 12.

[0060] 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. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
