Description

Technical Field

[0001] The utility model belongs to the technical field of casting processing, and in particular relates to a casting cooling environment regulating device. Background Art

[0002] After the casting process is completed, the casting needs to be cooled. When the casting is cooled, cracks and segregation may occur in the casting due to poor control of the cooling speed. In the prior art, the cooling speed of the casting is generally controlled by adding cooling iron to increase the local cooling speed, thereby controlling the cooling speed of each part, or covering the surface of the mold with an insulating layer to control the overall cooling speed of the casting. The latter requires manual operation, which increases production costs. At this time, an environmental adjustment device is needed.

[0003] For example, patent CN213997760U discloses a casting cooling environment regulating device, which includes a channel for placing castings and a cover body covering the channel from above and both sides, a heating device and an air supply device are arranged on both sides of the cover body, and a dust collecting device is arranged on the top of the cover body.

[0004] During use of the above-mentioned casting cooling environment adjustment device, since the insulation curtain covers installed on both sides of the cover body are arranged at the openings at both ends, when personnel place the cast castings on multiple channels (conveyor tracks), personnel are also required to manually assist in lifting the insulation curtains at the inlet end of the cover body. In addition, since each time the channel (conveyor track) is operated to place castings, the previous batch of castings in the cover body carried on the channel (conveyor track) for cooling and heat preservation will be transported to the end of the track. At this moment, the insulation curtain at the outlet end of the cover body still needs another staff member to assist in lifting the insulation curtain for unloading operations. This process increases labor costs and also affects the loading and unloading efficiency to a certain extent. Utility Model Content

Moreover, since the channel (conveyor track) operates each time to place castings, the previous batch of castings in the cover body carried on the channel (conveyor track) for cooling and heat preservation will be transported to the end of the track. At this time, the heat insulation curtain at the outlet end of the cover body still needs another staff member to assist in lifting the heat insulation curtain for unloading operations.

One end of a rotating rod 424 is fixed to the middle of the two bevel gears 423, and the two ends of the two rotating rods 424 are connected to the two ends of the double-headed motor 425 respectively. The rotating rod 421 and its external upper mounting frame 41 are symmetrically distributed along the vertical central axis of the top of the cover body 1.

Secondly, when the castings are transported to the inside of the cover body 1 by the conveying rails 3 for cooling environment adjustment, the personnel can start the linkage opening and closing mechanism 4 again to make the insulation boards 44 on both sides of the cover body 1 continue to descend. Since multiple partitions 5 are provided at the bottom end of the insulation board 44, the distance between each two of the distributed partitions 5 can be directly opposite to the width of the channel frame 2 carrying the conveying rails 3.
