Spiral cooling device for super-thick mould core

Abstract

The invention discloses a spiral cooling device for a super-thick mould core. The spiral cooling device comprises a water inlet pipeline, a water return pipeline, a spiral block and a mould core of a mould, wherein a water inlet tube hole and a water return tube hole are formed in the spiral block; the water inlet pipeline is communicated with the water inlet tube hole of the spiral block; the water return pipeline is communicated with the water return tube hole of the spiral block; the spiral block is arranged in the mould core of the mould; the spiral block is in threaded connection with the mould core of the mould; the mould core of the mould and the spiral block form a sealed watertight chamber; the water inlet tube hole and the water return tube hole are communicated with the watertight chamber; water of the water inlet pipeline forms short water pressure in the watertight chamber between the mould core of the mould and the spiral block, then enters the water outlet pipeline along a spiral slot of the spiral block from the water inlet tube hole to the water return tube hole to carry out water circulation, and reaches a cooling part of the mould core of the mould to cool the mould core of the mould. The special cooling device is convenient in operation, sufficient in water volume of a storage chamber, smooth in water circulation, good in cooling effect and low in cost, and solves the technical problem that the cooling effect for the super-thick mould core is poor.

Description

technical field [0001] The invention relates to a cooling device, in particular to an ultra-thick core spiral cooling device. Background technique [0002] Mold core The part that constitutes the product space is called the molded part, that is, the mold as a whole, and the mold part that molds the inner surface of the product is called the core, also known as the sub-mold or the rear mold. From the appearance of the product mold, the protruding part is the core, and the concave part is the cavity (Cavity). The core and the cavity appear in pairs. The formed space is the shape of the mold product. The cooling device belongs to the field of production line auxiliary equipment. During the operation of various molds, many parts of them need to be cooled by cooling water, such as the rotating core of the threaded mold, to prevent product quality from being reduced or damage to the mold. The existing ultra-thick core spiral cooling device, the mold core wall thickness is not su...

AI Technical Summary

Problems solved by technology

The existing ultra-thick core spiral cooling device, the mold core wall thickness is not sufficiently cooled, resulting in deformation of the product during die-casting, and the core is easy to stick to aluminum during demoulding, and the surface roughness and product accuracy of the product cannot meet the requirements
