Hot-extrusion die of axial copper lock body

Abstract

The invention discloses a hot-extrusion die of an axial copper lock body. The hot-extrusion die comprises an upper die and a lower die, wherein the upper die comprises a die handle, an upper die plate, an upper die cushion plate, an upper fixing plate with an upper male die, an elastomer and a stripping cushion plate, which are sequentially connected from top to bottom; the lower die comprises a female die sleeve with a lower female die, a moving die sleeve with a moving die, a lower fixing plate, a lower die cushion plate, a lower die plate and a jacking rod fixing plate with a jacking rod; a guide hole and a first forming hole are sequentially formed in the upper male die from top to bottom; a second forming hole is formed in the lower female die; the guide hole is glidingly matched with a cylindrical head of a lower die core of which the lower end pushes against the lower die cushion plate and the upper end penetrates through the moving die and protrudes through the second forming hole; the lower die core also comprises a core rod consisting of a cylindrical rod and a square rod arranged on one side of the cylindrical rod; an inclined surface is arranged at the connecting place between the cylindrical rod and the cylindrical head of the core rod; and an arc surface is arranged at the connecting place between the square rod of the core rod and the inclined surface. By the hot-extrusion die of the axial copper lock body, the production efficiency and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of hot extrusion dies, in particular to an axial copper lock body hot extrusion die. Background technique [0002] There is a kind of axial copper lock body 21 at present, and its structure is as Figure 4 As shown, it includes a cylindrical head 21.1 and a cylindrical lock body 21.2. The axial copper lock body 21 is provided with irregular holes for installing the lock cylinder. The irregular holes include small cylindrical holes 21.3 with smaller diameters and larger diameter The large cylindrical hole 21.4, the side of the large cylindrical hole 21.4 is also connected to the square hole 21.5, the transition slope 21.6 is provided between the large cylindrical hole 21.4 and the small cylindrical hole 21.3, the square hole 21.5 and the transition slope 21.6 The connection is provided with a transitional arc 21.7. Existing processing of the axial copper lock body adopts a die-casting process, but the transi...

AI Technical Summary

Problems solved by technology

Existing processing of the axial copper lock body adopts a die-casting process, but the transition slope 21.6 and the arc surface 21.7 of the axial copper lock body produced by the die-casting production process are not easy to die-cast, and subsequent cutting processing is required, resulting in low production efficiency; The surface of the die-cast axial copper lock body has more burrs, and the inside is prone to pores, etc., which makes the product quality not high
