The drying cover is sleeved outside a sand mold, the heating device and an air circulating device are arranged on the drying cover and used for drying the sand mold in the drying cover, the amount of residual water in the sand mold is effectively reduced, the sand mold can be preheated, a casting environment is not affected by seasons and climates, and casting efficiency and product quality are improved.
Description
Technical field:
The utility model belongs to sand casting drying technology field, is specifically related to a kind of mold drying device.
Background technology:
Water-glass sand is because heat-resisting quantity is good, the cost of raw material is low, deformability is good, therefore more steel-casting foundry all adopts sodium silicate molding now, but the drying of waterglass sand mold is mostly adopted natural air drying, be characterized in that speed is slow, drying is not thorough, some enterprises adopt the flame dry tack free, if drying time is long, then cost is higher, but drying time is short then not thorough, and uneven drying is even.Particularly in the winter time or in the larger weather of the air humidity such as rain, the residual water yield of sand mold is higher, its residual water will be decomposed into gas in casting process, some discharge foundry goods, having little time of having discharged, and can be present in the foundry goods oxidation that has even can cause alloy or nonmetalloid with the form of pore, form oxide inclusions and be present on the crystal boundary, have a strong impact on mechanical property and the surface quality of foundry goods.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of mold drying device, it is that design one cover covers on the outer drying cover of sand mold, at drying cover heater and air circulation device is set simultaneously, by heater and air circulation device the sand mold in the drying cover is dried, effectively reduce the residual water yield in the sand mold, and can the preheating sand mold, realized that the casting environment is not subjected to season and climatic influences, has improved casting efficient and product quality.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of mold drying device, wherein: comprise drying cover, heater and blower fan, described drying cover is bottom surface opening guard shield, the sidewall of drying cover comprises heat-insulation layer and the outer finishing coat that sets gradually from inside to outside, the top board middle part of drying cover is provided with blower fan, and the inwall of drying cover is provided with heater.
Further, described heater is infrared hot plate, and infrared hot plate is arranged on the inboard of top board and the side plate of drying cover.
Further, described drying cover is the square structure of bottom surface opening.
Further, described blower fan comprises motor, rotating shaft and fan blade, and the top board of drying cover is passed in rotating shaft, and fan blade is arranged on an end that is positioned at drying cover of rotating shaft, and the outer end of drying cover that is arranged on of rotating shaft is connected with the output shaft of motor.
Further, described heat-insulation layer is fiberboard.
Further, described fan blade is outside equipped with protective cover.
The beneficial effects of the utility model are:
1, the utility model is that design one cover covers on the outer drying cover of sand mold, simultaneously at drying cover heater and air circulation device are set, by heater and air circulation device the sand mold in the drying cover is dried, effectively reduce the residual water yield in the sand mold, and can the preheating sand mold, realized that the casting environment is not subjected to season and climatic influences, has improved casting efficient and product quality.
2, the utility model adopts the infrared hot plate heating, and thermal source is stable, and temperature fluctuation range is little, and electrical heating efficiency is high, cleanliness without any pollution; Adopt blower fan to promote thermal cycle, can guarantee that sand mold is able to thermally equivalent, drying efficiency is high; Adopt rotating shaft to connect between blower motor and the blade, there is the fiberboard heat-insulation and heat-preservation centre, prevents motor overheating; The fiberboard that the drying cover inner surface is installed has reduced the heat radiation to surrounding environment, has guaranteed workman's work situation; Baker itself is simple in structure, and is easy to operate, low to operator's specification requirement.
3, the utility model is simple in structure, easy to use, effective, can effectively solve the problem that the air-dry drying of sand mold natural air drying or flame is not thorough, have a strong impact on casting efficient and castability.
