Technical field
Patent of the present invention relates to a kind of cooling device, in particular for the high pressure spot cooler that die casting mould core local fixed point accurately cools.
Background technology
In Die Casting, extremely important to the regulation and control of mold temperature, for the cooling of the narrow shaped cast part in dark chamber, the cooling of core part that the most difficult is, usually adopts iris type cooling, offers blind hole at core center, dividing plate is loaded in blind hole.Its course of work is: normal pressure cooling water is flowed into by water inlet, and the side along dividing plate flows to core top and cools, then leads to delivery port by the opposite side of dividing plate, and heat is discharged rapidly along with circulating of cooling water, reaches the object of cooling core.
For iris type cooling, the water temperature of dividing plate both sides is different, so the mandrel temperatures of dividing plate both sides finally can be caused different, inhomogeneous cooling is even, so when Workpiece shaping, and the diverse location outside core, the shrinkage factor of workpiece is different, thus makes the workpiece of die casting produce distortion, affects quality.
patent of invention content
The object of patent of the present invention for overcoming that current die casting adopts the cooling of normal pressure current and inhomogeneous cooling is even, causes the shortcoming of die casting workpiece deformation exactly, provides a kind of high pressure spot cooler by the accurate cooling of High-Pressure Water fixed point.
For realizing above object, the technical scheme of patent of the present invention is as follows:
