A grenade inner liner injection mold structure

Abstract

The invention belongs to the field of injection moulds and discloses a hand grenade lining bush injection mould structure which comprises a moving mould and a fixed mould. A moving mould core is arranged on the bottom of the moving mould in an embedded manner. One or more rotating assemblies are arranged on the fixed mould. When the moving mould and the fixed mould are closed, the moving mould core and the end portions of the rotating assemblies are arranged vertically to form a forming cavity. The moving mould is provided with a steel column feeding opening. The steel column feeding opening penetrates through the upper surface of the moving mould and the moving mould core. According to the structure, the moving mould and the fixed mould are provided with the steel column feeding openingsand the rotating assemblies correspondingly, steel columns are fed into the forming cavity through the steel column feeding openings, by means of rotating of the rotating assemblies, the steel columnsdistributes uniformly in the forming cavity, thus the steel columns in a lining bush obtained after injection are distributed uniformly, it is ensured that the lining bush obtained after injection meets the requirement of production, and the yield is increased greatly.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold structure for a grenade inner liner. Background technique [0002] The inner liner is set inside the shell of the grenade. The existing production method of the inner liner is generally injection molding. The production efficiency of injection molding is high and it is convenient to add a certain amount of small-volume metal steel columns during the injection molding process of the inner liner. , by adding steel pillars in the inner bushing, these steel pillars are scattered after the grenade explodes to achieve the purpose of killing and destroying the target, so that the explosive power of the grenade is stronger. [0003] However, when the existing inner liner is produced by injection molding, because the shape of the steel column is a cylinder, its fluidity is poor, so it is easy to cause the uneven distribution of the steel column in the cavity, resulting in ...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing inner liner is produced by injection molding, because the shape of the steel column is a cylinder, its fluidity is poor, so it is easy to cause uneven distribution of the steel column in the cavity, resulting in the inner liner produced by injection molding. The distribution of steel columns inside is uneven, which does not meet the production requirements of the product, and the yield is low
