System.
Background technology
In liquid condition shaping manufacture field, molten condition or liquid are usually heated the material to, metal type dies are reinjected
It is central, material solidification is gradually cooling to, required part can be obtained after die sinking.First half in liquid condition shaping process
Section, i.e., during by material warms to fusing point material maintained above for molten condition or liquid, typical temperature is higher, particularly metal material
Material, fusing point be up to thousands of degrees Celsius, it is necessary to time it is longer, energy consumption is higher.Such as fine copper fusing point is 1083 DEG C, in the liquid of fine copper
During processing, keep fine copper be liquid while, it is necessary to ensure liquid metal filling metal die during with metal die
Good mobility is still kept after contact cooling, to be filled up completely with full die cavity.Therefore, holding is needed to compare material in industrial production
Fusing point higher temperature, can meet the requirement in liquid material added metal type mould.Pure copper material mentioned above is in industry
Usually require to keep that more than 1100 DEG C of temperature filling mold cavity can be carried out in production.However, the liquid of higher temperature or molten
Melt state material causes cool time longer after filling die cavity, production efficiency reduction.
To improve production efficiency, metal type dies are generally cooled down by the way of cooling water channel.By in mould type
Set the water circulated in cooling water channel, cooling water channel constantly by the heat transfer in metal die into water near chamber and be delivered to
Mold exterior, mould own temperature reduction, by the heat in the liquid or the material of molten condition that absorb higher temperature, so that real
Existing cooling down workpiece, reaches the effect for accelerating material solidification in mold cavity.
