[0002] Extrusion die is a kind of forming die. In the copper wire production process, it is usually necessary to use an extrusion die to extrude the copper wire into copper wires of different specifications. The wire inlet and shaping port of the existing copper wire extrusion machine die The transition between the two is relatively large, and it is easy to cause the accumulation of materials between the two, resulting in excessive heat, which will accelerate the aging of the mold and affect the extrusion effect; at the same time, the existing copper wire extrusion machine mold has poor heat dissipation effect, which affects the use

Embodiment Construction
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] Such as Figures 1 to 4 As shown, the die for the copper wire extruder of the present invention includes a body 1, the front end of the body 1 is provided with an outlet 2, the rear end is provided with an inlet 3, and a wire inlet 3 is provided between the inlet 3 and the outlet 2 There is a stereotyped mouth 4. The wire inlet 3, the shaped hole 4 and the wire outlet 2 are all square and rounded, wherein the size of the shaped hole 4 and the wire outlet 2 are the same, and the wire inlet 3 is larger than the shaped hole 4. The distance between the wire inlet 3 and the shaping hole 4 is gradually reduced, and slopes are formed between each surface, which can greatly reduce the accumulation of copper wire materials between the wire inlet 3 and the shaping hole 4, and reduce the generation of heat. The slope angle between the wire inlet 3 and the s...

Abstract
The invention belongs to the field of cable machining equipment and discloses a die for a copper wire extruding machine. The die comprises a body, one end of the body is provided with a wire inlet while the other end of the body is provided with a wire outlet, and a shaping port is formed between the wire inlet and the wire outlet. Each of the wire inlet, the shaping port and the wire outlet is in a square round angle shape, the wire inlet and the shaping port are uniform in size and both larger than the wire outlet, the body is gradually reduced in size from the wire inlet to the shaping port, and the length between the wire inlet and the shaping port is larger than that between the shaping port and the wire outlet. Since the body is gradually reduced in size from the wire inlet to the shaping port to form a slope, feeding of a great quantity of copper wire materials within a short time is avoided when the copper wire materials accelerate to pass through, hindering of surplus copper wire materials behind the die body is avoided, accumulation of the copper wire materials between the wire inlet and the shaping port is reduced, and accordingly heat generation is reduced, aging of the die body is decelerated, and service life of the die body is prolonged.
Description
technical field [0001] The invention relates to a metal mold, in particular to a mold for a copper wire extrusion machine, which belongs to the field of cable processing equipment.
