Then pour the melted metal or alloy into the wax mold, and after cooling, take it out to obtain the required part. In order to ensure that the dried wax mold melts to leave a more stable cavity structure, the surface of the wax mold needs to be repeatedly sandblasted, and generally, the wax mold needs to be dried after sandblasting.

There is a conveyor belt inside the drying box, and a plurality of drying grooves are evenly distributed on the conveyor belt. There are a plurality of ventilation openings on the back of the drying box, and the ventilation openings are connected to a wind storage structure behind the drying box. The air spraying nozzles are connected to the wind storage structure through air ducts. The outer circle of the drying box is a drying box shell, and there are a left shift button and a right shift button on the right side of the drying box shell.

[0007] Optionally, the drying table, the drying table opening and the drying grooves are adapted to each other.

[0008] Optionally, there is an increasing structure between the air spraying nozzles and the air ducts.

[0009] Optionally, there is a heating layer between the outer shell and the interior of the first air drying box.

[0010] Optionally, there is a grit collection box below the drying table, there is a rotating structure in the middle of the drying table, and a filter screen layer is around the rotating structure. The lower part of the filter screen layer is connected to the inside of the grit collection box.

[0011] Optionally, the front of the drying box is a visible door.

[0012] Optionally, the length of the drying box is three times that of the first air drying box.

[0013] Optionally, the drying table and the lifting rod are detachable.

[0014] By adopting the above technical solutions, in this case, the wax mold after sandblasting is dried through the heating layer inside the first air drying box, the air ducts are pressurized through the pressurizing structure, and then the details of the wax mold are air-dried. The cooling and further drying effects are achieved through the cooperation of the drying grooves on the conveyor belt and the ventilation openings, so that the drying speed is accelerated. The wax mold is more fully air-dried through the rotating structure. The grits falling during the drying and air-drying processes will fall into the grit collection box through the filter screen layer, avoiding the problem of difficult cleaning due to grit falling during the drying process.

[0015] In summary, the present utility model has at least the following beneficial effects:

[0016] The utility model adopts the combination of drying and air drying to perform preliminary water removal on the wax model. When the wax model enters the drying box, the drying speed is faster and the effect is better.

[0017] The utility model uses the drying box below the first air drying box, the air storage structure and the vent to dry the wax molds. There is no need to adjust the lifting and lowering for drying, and the operation is more convenient. A plurality of wax molds can be dried through the drying trough on the conveyor belt, and the drying environment is the same, avoiding the problem that the upper wax mold blocks the lower wax mold and causes insufficient drying of the wax mold.

[0018] The utility model enables the wax model to be air-dried more fully through the rotating structure. The sand and gravel that fall during the drying process will pass through the filter layer and fall into the sand and gravel collection box, avoiding the problem of sand and gravel falling during the drying process and difficulty in cleaning.
