[0002] A shielding cover is a tool used to shield electronic signals. Its function is to shield the internal circuit from the influence of external electromagnetic waves and the outward radiation of internal electromagnetic waves. When producing a shielding cover, it needs to be produced by stamping equipment and shaped by a mold. For example, the patent technology disclosed in prior art announcement number CN211613976U discloses a high-voltage shielding cover stretching mold. A thin-walled metal tube, preferably a copper tube, can be placed in the annular groove on the mold sleeve and the die. The square groove on the mold sleeve and the die is fixed with a liquid injection block. The liquid injection block is provided with a liquid inlet and a liquid outlet. Only a partition is provided to separate the liquid inlet and outlet. The metal tube is connected to the back of the liquid inlet and outlet of the liquid injection block, and the inlet and outlet of the metal tube are connected on both sides of the partition.

[0003] When the above device is in use, an annular groove and a square groove are opened on the contact surface of the mold sleeve and the die, the annular metal tube is sleeved in the annular groove, and the inlet and outlet of the metal tube are connected to the injection block stuck in the square groove. The injection port and the outlet on the injection block are responsible for the circulation of the coolant of the metal tube. However, when the metal tube is replaced, if the thickness of some metal tubes is different, it is easy for the upper end face of the metal tube to be unable to fit stably with the lower end face of the stamping base, and the stability of the installation becomes poor, thereby affecting the heat dissipation effect of the stamping base.

[0027] like Figure 3 and 4 As shown, a concave mounting groove 14 is provided in the middle of the upper end of the support base plate 2, and a heat dissipation pipe 16 is provided on the inner end surface of the concave mounting groove 14, and a support pad 15 is provided at the lower end of the heat dissipation pipe 16.
