Be the structural representation for the cooling system of mould described in this detailed description of the invention shown in accompanying drawing 1, comprise die ontology 10 and cooling device, described cooling device is water-cooled, comprises multiple cooling unit being close to die ontology 10 surface.Die ontology 10 described in present embodiment is moulds of automotive hub, according to the design feature of mould, cooling unit comprises PCD water-cooled 21, counterdie slope water-cooled 22, rib water-cooled 23, rib tail water cooling 24, shunting fuse water-cooled 25, peace face water-cooled 26, patrix slope water-cooled 27 and Bian Mo rib point water-cooled 28.
PCD water-cooled 21 and counterdie slope water-cooled 22 adopt independently water inlet pipe 211 and 221 separately, and share an outlet pipe 212; Rib water-cooled 23 and rib tail water cooling 24 adopt independently water inlet pipe 231 and 241 separately, and share an outlet pipe 232.
Shunting fuse water-cooled 25, peace face water-cooled 26, patrix slope water-cooled 27 and Bian Mo rib point water-cooled 28 adopt independently water inlet pipe separately, are 251,261,271 and 281 respectively, and have independently outlet pipe 252,262,272 and 282 separately.
In other implementations, can further include the various water cooling unit being arranged on diverse location according to the feature of mould, and mate independent or shared outlet pipe, to meet the needs of mold cools down.
Screw is adopted to interfix between cooling unit and die ontology, such as PCD water-cooled 21, counterdie slope water-cooled 22, rib water-cooled 23 and rib tail water cooling 24 are arranged on the bottom of die ontology 10, namely screw 30 is adopted to be connected between they and die ontology 10, described screw 30 has elastic washer, when to prevent suddenly cold and hot, between each cooling unit and mould, produce gap.
The bottom surface moulding of the cooling tube of each cooling unit is consistent with the surface of mould, such as, with PCD water-cooled 21 in present embodiment, counterdie slope water-cooled 22, die ontology 10 surface of rib water-cooled 23 and rib tail water cooling 24 joint is flat, therefore the cooling tube bottom surface moulding of above-mentioned four water cooling plants is exactly flat, and patrix slope water-cooled 27 is and die ontology 10 joint, inclined-plane, therefore the bottom surface moulding of patrix slope water-cooled 27 cooling tube has a slope equally, to coordinate with the Slope Facies of die ontology 10, like this can enlarge active surface, improve radiating efficiency.
