A cooling device for processing metal steel castings

Abstract

The invention discloses a cooling device for processing metal steel castings, and relates to the technical field of metal processing. A support plate drives a die-casting mold to move downward, and after a pressure block is compressed, a sliding column drives a piston plate to move in a piston cylinder, and part of cooling water is discharged through an inlet and outlet hole. A water guide pipe can spray cooling water from a water spray port to the die-casting mold to cool it. Since the cooling water is discharged through the inlet and outlet hole and introduced into a water cooling box through a plurality of water leakage holes, the liquid level in the water cooling box rises, thereby improving the cooling effect on the die-casting mold and the metal steel casting. After the die-casting mold moves upward, it does not contact the cooling water. Since the water mist evaporates after the die-casting mold is cooled, a heat dissipation fan can blow away the generated high-temperature water mist, thereby accelerating the heat dissipation speed, reciprocating the die-casting mold, and cooling the die-casting mold in a spraying, immersion and air cooling manner, thereby preventing the metal steel casting from being cooled too slowly or unevenly to cause deformation or cracks, thereby improving the quality of the metal steel casting.

Description

[0001] The invention relates to the technical field of metal processing, in particular to a cooling device for processing metal steel castings. Background Art

[0002] In the process of processing metal castings, the pre-prepared metal raw materials are placed in a melting furnace for heating until the raw materials are completely melted into liquid metal. The liquid metal is then poured into a die-casting mold to form a metal workpiece. After the metal fills the die-casting mold, it needs to be cooled quickly to promote the rapid solidification of the metal.

[0003] In cooling the formed metal steel castings, in order to improve the cooling effect, spraying, air cooling or cooling water is introduced through the water channel in the mold to cool down the mold.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention forms a metal steel casting by pouring liquid metal into a die-casting mold. When cooling the die-casting mold and the metal steel casting, cooling water is poured into a water cooling box and a water storage tank, and the motor is controlled to drive the driving gear to rotate. Because the two driving gears are connected by a steel belt, the rotating rods and the columns at the bottom of the two driving gears rotate synchronously. During the rotation of the column, the slide seat can slide in the spiral groove, so that the slide seat drives the supporting rod to move downward through the supporting block, the connecting block and the cross bar, and the supporting rod drives the die-casting mold to move downward through the supporting plate. In the process of pushing the pressing block to move when the supporting plate moves downward, the sliding column drives the piston plate to move in the piston cylinder, so that the cooling water in the piston cylinder can be pushed into multiple water pipes, and part of the cooling water is discharged through the inlet and outlet holes. In this process, the water pipe can spray the cooling water from the water spray port on the water distribution box to the die-casting mold to cool it. Because the cooling water is discharged through the inlet and outlet holes, the cooling water is discharged from the water spray port on the water distribution box to the die-casting mold. The water vapor is discharged from the holes and introduced into the water cooling box through multiple water leakage holes, so that the liquid level in the water cooling box rises and fully contacts with the die-casting mold, thereby improving the cooling effect on the die-casting mold and the metal steel castings. When the slide moves to the bottom of the column, it can slide into another spiral groove by itself. During the rotation of the column, the support rod drives the support plate and the die-casting mold to move upward, so that the die-casting mold does not contact with the cooling water. The water mist evaporates after the die-casting mold is cooled down. In conjunction with the setting of the cooling fan on the support frame, the high-temperature water mist can be blown away, thereby accelerating the heat dissipation rate. In this way, the die-casting mold is moved back and forth up and down, and the die-casting mold is cooled by spraying, immersion and air cooling, which greatly improves the cooling effect on the metal steel castings in the die-casting mold, improves the cooling uniformity of the metal steel castings, prevents the metal steel castings from cooling too slowly or unevenly to cause deformation or cracks, and thus improves the quality of the metal steel castings.

[0019] 2. In the process of the present invention driving the die-casting mold to move upward by the support plate, the pressure block is supported by the elastic force of the spring, so that the pressure block moves upward in the piston cylinder through the piston plate, so that an adsorption force is generated inside the piston cylinder, and the water in the water cooling box flows into the water storage tank through the leakage hole, and the water in the water storage tank is sucked into the piston cylinder through the inlet and outlet holes, so that the liquid level in the water cooling box can be lowered to facilitate the next spraying and immersion cooling of the die-casting mold. Because a plurality of heat sinks are installed around the die-casting mold, four water distribution boxes are respectively arranged around the die-casting mold, and the heat sinks can expand the heat dissipation range, so that the heat can be quickly dissipated after it contacts the cold source, and the cooling effect on the die-casting mold and metal castings is further improved.
