The die cavity to form wheel hub is surrounded jointly, and the side wall of bed die 2 is embedded with several cooling tubes 7, and the both ends of cooling tube 7 are welded with No.1
Drainpipe 8 and No.1 feed pipe 9, cooling tube 7 include wide diameter tube 14, the cold pipe 13 of thin diameter tube 15 and mould bottom, and the outside of cooling tube 7 is equal
It is socketed with and mends cold pipe 10, several cold pipes 10 of benefit are respectively positioned on 2 outside of bed die, and the both ends of bed die 2 are respectively welded No. two feed pipes 11
With No. two drainpipes 12.
Cooling tube 7 is whole serpentine-like, and cooling tube 7 includes the cold pipe 13 in a mould bottom, several thin diameter tubes 15 and several wide diameter tubes
14, wide diameter tube 14, the cold pipe 13 of thin diameter tube 15 and mould bottom are sequentially communicated, and carry out the heat dissipation of multiple spot specific aim using single tube, solve wheel
The complex problem of hub mold multiple spot specific aim cooling body stringing, wide diameter tube 14 and thin diameter tube 15 are arranged alternately, wide diameter tube
14 and thin diameter tube 15 be in "U" shaped, adjacent wide diameter tube 14 and thin diameter tube 15 weld, and the radius of wide diameter tube 14 is greater than thin diameter tube 15
Radius, be connected pipeline in, caliber is inversely proportional with fluid flow rate, can effectively exchange heat, and mends cold pipe 10 in the shape of a spiral, mends cold pipe 10
Outer wall is close to 7 outer wall of cooling tube, and the junction of wide diameter tube 14 and thin diameter tube 15 is located at the outside for mending cold pipe 10,14 He of wide diameter tube
The middle part of thin diameter tube 15 is embedded in 2 side wall of bed die, and the junction of wide diameter tube 14 and thin diameter tube 15 is located at 2 outside of bed die, slightly
Diameter pipe 14 is close at wheel rim heavy wall, and thin diameter tube 15 is close at wheel rim thin-walled, and wide diameter tube 14 and 15 junction of thin diameter tube are only by cold
Hot water influences, and not by bed die 2 and mends the cold interference of pipe 10, is not likely to produce overheat or surfusion, can be at wheel rim different wall thickness
Carry out difference heat exchange, can promote at the variant wall thickness of wheel rim closer to and meanwhile it is cooling, increase the cast globality of wheel rim, one
Number feed pipe 9 is welded on the lower end of cooling tube 7, and No.1 drainpipe 8 is welded on the upper end of cooling tube 7, and several cooling tubes 7 surround bottom
2 central axis of mould forms subcircular structure, and several 7 equidistant arrangements of cooling tube can drain the air in cooling tube 7 from the bottom to top, keep away
Air-trapping phenomena is exempted from.
Specifically, the present invention in use, external equipment by high-pressure hydraulic pump by cold water be passed through No.1 feed pipe 9 and No. two to
Water pipe 11, cold water are introduced into the cold pipe 13 in mould bottom from No.1 feed pipe 9, and subsequent cold water enters wide diameter tube 14 and thin diameter tube 15, can
Drain the air in cooling tube 7 from the bottom to top, avoid air-trapping phenomena, in the pipeline that is connected, caliber and fluid flow rate at
Inverse ratio, the chilled water flow velocity in wide diameter tube 14 is slow, and unit length inner cold water reserves are big, and the chilled water flow velocity in thin diameter tube 15 is fast, unit
Length inner cold water reserves are small, can form heat exchange difference, i.e. caliber is thicker, and cold water heat-exchange time is longer, can effective heat exchange area it is big,
Can effectively heat exchange amount it is big, accessible heat transfer effect is better, so as to promote for difference heat exchange is carried out at wheel rim different wall thickness
Make at the variant wall thickness of wheel rim closer to and meanwhile it is cooling, increase the cast globality of wheel rim, improve wheel rim quality, the skill
The difficult point of art is that wide diameter tube 14 and thin diameter tube 15 are difficult to cast manufacture, therefore can only take the mode of welding, due to wide diameter tube
14 and the different radius construction of thin diameter tube 15, it is easy during hot and cold alternation, shrinkage fracture occurs in junction or expansion is disconnected
The case where splitting, the wide diameter tube 14 of this mold and 15 junction of thin diameter tube are located at bed die 2 and mend 10 outside of cold pipe, junction only by
Hot and cold water influences, and not by bed die 2 and mends the cold interference of pipe 10, is not likely to produce overheat or surfusion, ensure that the feasible of the technology
Property, the heat-exchanging water that cooling tube 7 is guided out can be cooled down by mending cold pipe 10, enter back into bed die 2 after heat-exchanging water is cooling, can keep changing
The heat exchange property of hot water is, it can be achieved that be quickly cooled down.
