Hot-extrusion die of spring lock head lock body

Abstract

The invention discloses a hot-extrusion die of a spring lock head 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, an elastomer and a stripping plate; the upper die plate, the upper die cushion plate, the upper fixing plate, the elastomer and the stripping plate are sequentially connected from top to bottom; the lower die comprises a female die sleeve, a lower moving die sleeve, a lower fixing plate and a lower die plate which are sequentially connected from top to bottom; the upper fixing plate is provided with an upper male die; a blind hole is formed in the upper male die; the lower fixing plate is provided with a lower male die; when the upper part of the lower male die is closed, the lower male die is glidingly matched in the blind hole; a lower female die is sleeved on the female die sleeve and is provided with a first step hole; the lower moving die sleeve is provided with a second step hole; the lower male die is partially positioned in the first step hole and the second step hole and is coaxial with the first step hole and the second step hole; and a product jacking device is glidingly matched in the first step hole and the second step hole. The hot-extrusion die is relatively low in production cost and high in production efficiency.

Description

Technical field [0001] The invention relates to the field of hot extrusion molding molds, in particular to a hot extrusion mold for a pin lock body. Background technique [0002] To protect the safety of property, various locks are often used in daily life, such as padlocks, tumbler locks, drawer locks, mortise door locks and spherical door locks. As an important daily necessities, people put forward the safety of locks In order to meet higher and higher requirements, the core of the safety of the lock is the lock, so the research on the lock is getting more and more in-depth. For example, the patent with the authorized announcement number CN100371558C discloses a pinhole with axial rotation. A pinball lock head, the lock head includes a lock shell, a lock body, a lock core and other components. In the prior art, the lock body in the lock is usually formed by cutting a cylindrical blank, which is required in the cutting process Cutting off excess materials will result in greater...

[0002] In order to protect the safety of property in daily life, various locks are often used, such as padlocks, tumbler locks, drawer locks, mortise door locks and spherical door locks. higher and higher requirements, and the core of lock safety is the lock head, so the research on the lock head is getting more and more in-depth. The pin lock head, the lock head includes the lock head shell, the lock body, the lock cylinder and other components. In the prior art, the lock body in the lock head is usually formed by cutting the cylindrical blank. Due to the need for Cut off excess material, the waste of raw materials is large, and the cutting process takes more time, the production efficiency is low, the production cost increases, and the economic benefit decreases
