A sealing block 6 is arranged between the lower parts of the wire inlet groove 9 and the wire outlet groove 10 of the main template 3 and the assembly sinking groove 26 (refer to the attached figures 2 and 3 in the specification). A sealing through hole (not shown in the attached figures of the specification) is arranged in the sealing block 6; the wire inlet groove 9 and the wire outlet groove 10 of the main template 3 are communicated with the assembly sinking groove 26 through sealed through holes; the purpose of the sealing block 6 is to: so that the sealing block 6 can separate the wire inlet groove 9 and the wire outlet groove 10 from the assembly sinking groove 26 to prevent the cooling wind in the wire inlet groove 9 and the cooling water in the wire outlet groove 10 from entering the assembly sinking groove 26 along with the wires 27 during operation.

The purpose of the avoiding counter bore 17 is to: when the auxiliary template 4 is buckled with the main template 3, the sealing block 6 in the main template 3 can be inserted into the avoiding counter bore 17, and the problem of interference between the sealing block 6 and the auxiliary template 4 is avoided.
The upper end of the main template 3 is symmetrically provided with an incoming line guide plate 1 and an outgoing line guide plate 2 (refer to the attached figures 1 and 2 in the specification). When the auxiliary template 4 is buckled with the main template 3, the wire inlet guide plate 1 and the wire outlet guide plate 2 are hermetically connected with the upper end of the auxiliary template 4.
A conical wire inlet hole 18 is formed in the wire inlet guide plate 1; the wire inlet holes 18 are in an opposing relationship with the wire inlet grooves 9 of the main template 3 and the sub-template 4. In operation, wires may enter the wire feed slot 9 through the wire feed hole 18.

When the wire drawing annealing cooling die for the cable copper conductor works, the auxiliary die plate 4 and the main die plate 3 are in a buckling state, and an external cooling air supply device can supply air to the wire inlet groove 9 through the air inlet hole 14 and is discharged outside through the wire inlet hole 18 on the wire inlet guide plate 1; thus, a cooling air channel can be formed in the space formed by the auxiliary template 4 and the wire inlet groove 9 of the main template 3; meanwhile, an external cooling water supply device can supply cooling water to the wire outlet groove 10 through the water inlet hole 16, and the cooling water in the wire outlet groove 10 can flow out of the annealing cooling die through the overflow hole 15. Thus, a cooling water passage is formed in the space formed by the outlet grooves 10 of the sub-mold 4 and the main mold 3.
During operation, a lead 27 to be annealed and cooled enters the wire inlet groove 9 through the wire inlet hole 18 on the wire inlet guide plate 1, passes through the sealing block 6, enters the assembly sink groove 26, reverses around the reversing guide wheel 5, enters the wire outlet groove 10 through the sealing block 6, and finally is output out of the cooling die through the wire outlet hole A21 and the wire outlet hole B23; in the process, the wire 27 is subjected to the wire drawing annealing cooling process in a mode of primary cooling of cooling air in the wire inlet groove 9 and secondary cooling of cooling water in the wire outlet groove 10, and the problem of high cooling rate existing in the traditional annealing cooling mode of directly using cooling water for cooling is solved. In addition, the wire 27 completes the cooling work by passing through cooling air and cooling water during the work, and the problem of uneven cooling existing in the existing spray cooling mode cannot be necessarily caused.
