Abstract
The utility model discloses a sand core cooling structure of a die, which is characterized in that an air suction pipe is fixedly connected to a sand core of the die, the other end of the air suction pipe is connected with a three-way valve, the other two ports of the three-way valve are respectively connected with an air blow pipe and an air output pipe, the air blow pipe extends into an inner air blow pipe inside the three-way valve, the orifice of the inner air blow pipe in the three-way valve rises above that of the air suction pipe, and the other end of the air blow pipe is connected with an air blow device. The utility model has the advantages of obvious cooling effect, simple structure, and low cost.
Description
Technical field
The utility model belongs to casting field, relates to the local cooling structure of a kind of mould core specifically.
Background technology
At the gravity-assist pouring part position of core is arranged, because the heat transfer speed of core does not have the heat transfer speed of mould steel fast, so it is too high the core local temperature to occur, the thermojunction position easily produces the situation of shrinkage cavity, and therefore produces casting flaw.Present technology generally adopts the change running channel, or is coated with the method for Quench coating at core, though can improve the situation of core hot-spot, can not reach desirable effect.
Summary of the invention
The purpose of this utility model is in order to solve the problem of the too high easy generation shrinkage cavity of above-mentioned core local temperature, to provide a kind of core local cooling structure.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of core cooling structure of mould, it is characterized in that, a fixedly connected air intake duct on the core of mould, the other end of air intake duct connects threeway, and two other port of threeway connects gas blow pipe and escape pipe respectively, and gas blow pipe extends to interior gas blow pipe in threeway inside, the mouth of pipe of gas blow pipe is crossed the mouth of pipe of air intake duct in threeway, and the other end of gas blow pipe connects blowning installation.
Air intake duct can be fixed on the core print position of core.
Gas blow pipe and escape pipe can be fixed on the mould.
Blowning installation can be an air compressor.
The utlity model has following advantage: (1) cooling effect is obvious.Taking before the technical solutions of the utility model, the inventor once attempted using traditional change running channel, was coated with the method for Quench coating at core, all can not eradicate the shrinkage cavity defect at thermojunction position.After adopting technical solutions of the utility model, effect is very desirable, and the core temperature obviously descends, and casting quality obviously improves.(2) simple in structure, with low cost.The utility model adopts a small amount of common pipe fitting to realize, the compressed air of air blowing usefulness also is easy to get at the casting factory building, so technical solutions of the utility model are easy to realize.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is specifically described.
Extremely shown in Figure 7 as Fig. 1, on core 1, preferably at the core print position, a fixedly connected air intake duct 2, the other end of air intake duct connects threeway 3, and two other port of threeway connects gas blow pipe 4 and escape pipe 5 respectively, and gas blow pipe 4 is gas blow pipe 6 in threeway inside extends to, the mouth of pipe of gas blow pipe 6 is crossed the mouth of pipe of air intake duct 2 in threeway, and the other end of gas blow pipe connects blowning installation.Send into the gas that flows fast in gas blow pipe 4, this air flow stream enters escape pipe after crossing the interior interior gas blow pipe mouth of pipe of threeway and the escape pipe mouth of pipe, discharges from the other end of escape pipe.Air-flow is in each pipe in the quick flow process, produce negative pressure between the interior gas blow pipe mouth of pipe in threeway and the escape pipe mouth of pipe, the air that this negative pressure can be carried in the air intake duct 2 is discharged along with quick air-flow enters escape pipe 5 backs together, can make the high-temperature gas of assembling in the air intake duct 2 be discharged to the mould outside thus, and then realize the purpose of core 1 heat radiation.The interior gas blow pipe mouth of pipe is crossed the air intake duct mouth of pipe, can prevent quick air flow direction air intake duct.
Gas blow pipe and escape pipe can be fixed on the mould.
Blowning installation can be an air compressor.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
