Technical Field

The utility model relates to an investment casting technical field, in particular to air cooling reduces device of investment casting shell inner chamber temperature.

Background

In investment precision casting, the shrinkage porosity defect of a casting is a difficult problem frequently encountered in the casting industry, the influence degree on the castings with different purposes is different, particularly the castings with pressure requirements are not allowed to have the shrinkage porosity defect, otherwise, leakage occurs to influence the use, but the shrinkage porosity defect of the casting is not easy to solve, the casting structure is analyzed specifically, a proper and effective solution is adopted for different castings, for example, a pouring system is arranged reasonably, the reinforced molten steel feeding amount is increased, and the like, and the shrinkage porosity defect of the casting is reduced. This is novel through reducing shell inner chamber temperature fast, makes the foundry goods cooling solidification earlier, and the cooling solidification behind the rising head to solve or reduce the defect of foundry goods shrinkage porosity.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a device of air cooling reduction of melt mould casting mould shell inner chamber temperature can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a device that air cooling reduces investment casting shell inner chamber temperature, includes atmospheric pressure receiving pipe, atmospheric pressure receiving pipe one end intercommunication air compression device, the other end intercommunication atmospheric pressure steam receiving pipe of atmospheric pressure receiving pipe, the side intercommunication rubber tube of atmospheric pressure steam receiving pipe, the rubber tube passes through connector and copper ring union coupling, the iron frame net is erect to the top of copper ring pipe, the air vent is seted up towards one side of iron frame net to the copper ring pipe, a tip that the rubber tube is close to atmospheric pressure steam receiving pipe is equipped with the atmospheric pressure switch.

Preferably, the lower end of the air pressure water vapor receiving pipe is communicated with a drain pipe, and a drain switch is installed on the drain pipe.

Preferably, the part of the copper ring pipe below the iron frame net is spirally arranged.
