Description

Technical Field

[0002] In the prior art, a granular refractory material is used to prepare molding sand and core sand in casting production. The amount of casting sand is the largest in sand casting production. The molding sand is in direct contact with the liquid metal or is very close to the liquid metal during the pouring process. When the pouring is completed until the casting is taken out of the mold, the molding sand maintains a high temperature and cannot be molded immediately. Therefore, it needs to be cooled. Clamp-type cooling, also known as jacket cooling, is a cooling technology mainly used in high-temperature and high-pressure equipment. It covers the outside of the equipment with a metal jacket, injects cooling medium into the jacket, and circulates the cooling medium through the jacket under high temperature and high pressure conditions to achieve the effect of cooling the equipment.

A method for using a clamping cooling device for metal casting equipment, characterized in that: A clamping cooling device for a metal casting device according to any one of claims 1 to 8 is used, comprising the following steps: S1, turning on the cooling device (1) and the cooling mechanism (2), pouring the molding sand to be cooled into the cooling tank (23) through the feeding port (13), and driving the motor 12 to drive the cooling fan (112) and the rotating rod (24) to rotate; S2, the cooling fan (112) cools the molding sand in the cooling tank (23), the rotating rod (24) drives the stirring cooling pipe (27) to rotate, the stirring cooling pipe (27) stirs the molding sand in the cooling tank (23), so that the molding sand is cooled by heat, and the refrigeration evaporator (21) can transport the low-temperature cooling water inside the refrigeration evaporator (21) to the liquid supply pipe 1 (210) and the liquid supply pipe 2 (213) through the liquid outlet pipe (216); S3, cooling water reaches the connecting bottom pipe (29) through the liquid supply pipe 1 (210), and then enters the cooling clamp pipe (28) through the plurality of through holes (214). The cooling water in the cooling clamp pipe (28) is transported upward to the connecting top pipe (211), and finally transported back to the refrigeration evaporator (21) through the connecting pipe (212) and the liquid return pipe (22); S4, the cooling water reaches the movable tube (26) through the second liquid supply pipe (213), and then flows into the stirring cooling tube (27) through the movable tube (26). The cooling water first flows from top to bottom in the stirring cooling tube (27), and then flows from bottom to top into the connecting top tube (211), and finally is transported back to the refrigeration evaporator (21) through the connecting tube (212) and the return liquid pipe (22); S5, cooling water circulates in the cooling clamp tube (28) and the stirring cooling tube (27), continuously taking away the heat of the molding sand and lowering the temperature of the molding sand; S6. When the temperature of the molding sand reaches the required temperature, the electric push rod (18) is turned on. The electric push rod (18) drives the baffle (19) to move to one side through the driving rod (110), and the molding sand in the cooling tank (23) is discharged from the device through the discharge pipe (17).
