Summary of the invention
The utility model is at least one defect overcoming described in above-mentioned prior art, and pedal trailing wheel mould core water-cooling structure is provided, and can reduce the cooling time of aluminium alloy wheel hub moulding by casting, ensures effectively to improve pedal trailing wheel casting class and produces.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: pedal trailing wheel mould core water-cooling structure, wherein, comprise core rod, be located at the perforate in core rod, also comprise water cooled pipeline and circulation duct, water cooled pipeline is connected in perforate and injects cooling water with perforate, and the water cooled pipeline other end is connected with circulation duct.
In the utility model, have perforate from core rod bottom, perforate access water cooled pipeline, cooling water, from water cooled pipeline ejection prod cast in-core wall, flows out along perforate, and then flows out along circulation duct.By the direct water-cooling of core rod inside, accelerate the cooling velocity of wheel hub, obviously reduce cool time.
Further, described perforate is vertically located in core rod, and perforate bottom connects water cooled pipeline.In this programme, the circulation that perforate is conducive to water is vertically set, cooling water sprays prod cast in-core wall from water cooled pipeline, and then flows out along perforate, can accelerate like this water circulation efficiency, has reduced cool time.
Further, described the number of openings is 4, and perforate is evenly located in core rod, and the central angle on the section of core rod between each perforate is 90 degree.Described water cooled pipeline quantity is also 4, and each water cooled pipeline position is corresponding with each position of opening.
4 corresponding 4 water cooled pipelines of perforate, above-mentioned quantity is proper, if perforate and water cooled pipeline quantity are greater than 4, can cause entering the dilutional hyponatremia in core rod, causes the waste of water; If perforate and water cooled pipeline quantity are less than 4, can cause the wheel hub can not be cooling in time, increase cool time, cause production efficiency to decline.
Further, described circulation duct is shaped as annular.In the utility model, water-cooling system is switched to internal cooling by external refrigeration, utilizes annular circulation duct that water circulation is flowed.
Further, described perforate top and core rod distance from top are 10mm, and opening diameter is 12mm.
In the utility model, distance is applicable to for 10mm makes the length of perforate, and cooling water sprays prod cast in-core wall from water cooled pipeline, and then flows out along perforate, can be effectively cooling to core rod.Opening diameter is 12mm and water cooled pipeline adaptation, also can make the water capacity easily inject.
Compared with prior art, beneficial effect is: the utility model, by the direct water-cooling of core rod inside, has been accelerated the cooling velocity of wheel hub, has obviously reduced cool time.Further, can reduce the cooling time of aluminium alloy wheel hub moulding by casting, ensure effectively to improve pedal trailing wheel casting class and produce.

Detailed description of the invention
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
As shown in Fig. 3-6, pedal trailing wheel mould core water-cooling structure, wherein, comprise core rod 1, be located at the perforate 11 in core rod 1, also comprise water cooled pipeline 12 and circulation duct 13, water cooled pipeline 12 is connected with perforate 11 to the interior injection cooling water of perforate 11, and water cooled pipeline 12 other ends are connected with circulation duct 13.
In the present embodiment, have perforate 11 from core rod 1 bottom, perforate 11 accesses water cooled pipeline 12, and cooling water impacts core rod 1 inwall from water cooled pipeline 12 ejections, flows out along perforate 11, and Fig. 5 arrow represents water (flow) direction, and then flows out along circulation duct 13.By the direct water-cooling of core rod 1 inside, accelerate the cooling velocity of wheel hub, obviously reduce cool time.
