DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The method of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0024] Referring to Figure 1 , Figure 2 , a multi-directional forging die for low-loss T-shaped copper bars includes an upper die backing plate 1 and a lower die backing plate 2. An upper die 4 is installed on the lower surface of the upper die backing plate 1, and a lower die 3 is installed on the upper surface of the lower die backing plate 2. Installation cavities 7 are provided on the adjacent outer surfaces of the lower die 3 and the upper die 4. Forming blocks 9 are installed inside the installation cavities 7. Cooling cavities 8 are provided inside both the lower die 3 and the upper die 4. A plurality of heat dissipation fins 16 are integrally connected to the outer surface of the forming block 9, and the heat dissipation fins 16 are placed inside the cooling cavity 8. There are two forming blocks 9, and mutually matching cavities 10 are provided on the side surfaces of the two forming blocks 9 that are in contact with each other. A retaining strip is fixedly connected to the inner wall of the cooling cavity 8, and a plurality of through grooves are provided on the outer surface of the retaining strip, and the through grooves correspond to the positions of the plurality of heat dissipation fins 16 one by one. Water flow holes are provided on the symmetric side surfaces of the lower die 3 and the upper die 4, and connecting ends 6 are fixedly connected to the ports of the water flow holes. The forming block 9 can be flexibly and conveniently installed or disassembled, which can effectively improve the maintenance convenience of the die. Before using the die for extrusion forming, an external cooling water supply device is connected to the connecting end 6, so that the cooling water can effectively pass through the inside of the cooling cavity 8. Since a plurality of heat dissipation fins 16 are fixedly connected to the side surface of the forming block 9 and the heat dissipation fins 16 are placed inside the cooling cavity 8, the flowing cooling water can cool the forming block 9 at this time, which can effectively reduce the high-temperature loss of the forming block 9, and the practicability is effectively improved.

[0025] Referring to Figure 1 , on both symmetric sides of the lower die 3, a side cylinder backing plate 11 is provided respectively. A flange 12 is fixedly installed on the inner side surface of the side cylinder backing plate 11. A punch holder 13 is fixedly installed on the outer surface of one side of the flange 12. A first punch 14 is fixedly connected to the end of one punch holder 13, and a second punch 15 is fixedly connected to the end of the other punch holder 13. One end of the second punch 15 corresponds to the port position of the cavity 10. The first punch 14 and the second punch 15 can be installed on the telescopic end of the side cylinder through the side cylinder backing plate 11. During operation, the first punch 14 is made to abut against the side surfaces of the upper die 4 and the lower die 3, and then the second punch 15 is moved so that the second punch 15 enters the inside of the cavity 10 to extrude the raw material, thereby enabling the T-shaped copper bar to be integrally formed.

[0026] Referring to Figure 1 , on the symmetric side surfaces of the lower die 3 and the upper die 4, a pressing plate groove 5 is provided respectively. The lower die 3 and the upper die 4 can be limited and fixed by using a pressing plate in cooperation with the pressing plate groove 5.

[0027] Working principle: When in use, first install the mold at the designated position, then connect the external cooling water supply device to the connecting end 6, and then enable the cooling water to pass through the inside of the cooling cavity 8 in an orderly manner. At this time, the integral forming processing operation can be carried out. Heat one end of the raw material and then place it inside the cavity 10. Then close the lower mold 3 and the upper mold 4, and then extend the side cylinder so that the first punch 14 abuts on the side surfaces of the upper mold 4 and the lower mold 3. At the same time, enable the second punch 15 to enter the inside of the cavity 10 to extrude the raw material, thereby enabling the T-shaped copper bar to be integrally formed. During this process, the cooling water can effectively reduce the temperature of the forming block 9, thereby reducing the high-temperature loss of the mold. During the later use, once the cavity 10 is damaged, the forming block 9 can be directly replaced, and the operation is convenient.
