Description

Technical Field

[0001] The utility model relates to a casting mold cooling system, belonging to the technical field of casting mold cooling. Background Art

[0002] The casting mold needs to be cooled during use, and spot cooling is one of the ways to cool the casting mold. Therefore, multiple cooling pipes need to be connected to the casting mold to communicate with the cooling water channel in the casting mold. Valves are installed at the ends of the multiple cooling pipes away from the casting mold. In order to facilitate centralized management, multiple valves are centrally installed on the surface of the hollow seat to connect the hollow seat to the main cooling pipe. After opening the valve, the coolant can flow into the cooling water channel in the casting mold. Multiple valves are installed on the hollow seat in a threaded connection manner to facilitate the disassembly, assembly and replacement of the valves. At this time, multiple screw holes need to be processed on the hollow seat. This method will result in the situation where the thread in one screw hole is damaged and the entire hollow seat needs to be replaced, resulting in a waste of resources. Therefore, it is necessary to design a casting mold cooling system that does not require the processing of screw holes on the hollow seat. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a casting mold cooling system to solve the problems raised in the above-mentioned background technology. The utility model does not need to process screw holes for installing valves on the hollow seat, thereby avoiding the situation where the entire hollow seat needs to be replaced due to damage of the screw holes.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a casting mold cooling system, including a hollow seat, a base is connected and fixed to the lower end of the hollow seat, a plurality of vertically arranged rectangular grooves are provided on two parallel side surfaces of the hollow seat, a plug hole is provided in the rectangular groove, the plug hole is communicated with the internal space of the hollow seat, a straight pipe is inserted in the plug hole, a rectangular block connected and fixed to the straight pipe is sleeved on the straight pipe, the rectangular block is inserted in the rectangular groove, two U-shaped plates are sleeved on the hollow seat, a plurality of through holes matching the straight pipe are evenly provided on the side of the U-shaped plate facing the rectangular groove, one end of the straight pipe passes through the through hole and is installed with a valve for connecting the coolant pipeline, and both ends of the two U-shaped plates are connected and fixed by connecting pieces.

[0005] Furthermore, the connecting piece includes an ear plate, both ends of the two U-shaped plates are connected and fixed with ear plates, the two ear plates on one side of the hollow seat are in contact with each other, two circular holes are provided on one side of the ear plate, a bolt is inserted in the channel formed by the two aligned circular holes on the two ear plates on one side of the hollow seat, and a nut is threadedly connected to one end of the bolt.

[0006] Furthermore, a support ring is sleeved on the bolt, and the support ring is arranged between the bolt head and the ear plate. A plurality of short rods are equidistantly installed in a ring shape on a side of the support ring facing the ear plate, and one end of the short rods away from the support ring contacts the ear plate.

[0007] Furthermore, a plurality of blind holes are equidistantly formed in a circular shape on one side of the support ring facing the ear plate, and one end of the short rod is fixed in the blind hole.

[0008] Furthermore, a sealing sleeve is provided at one end of the straight pipe away from the valve, and the sealing sleeve is in contact with the inner wall of the insertion hole.

[0009] Furthermore, the upper surface of the base is sunken downward to form a groove, the open end of the hollow seat is connected and fixed in the groove, and two fixing holes are provided on the upper surface of the base, and the two fixing holes are symmetrically arranged about the hollow seat.

[0010] Beneficial effects of the utility model:

[0011] 1. Pass one end of the straight pipe through the hole on the U-shaped plate, and then insert one end of the straight pipe installation sealing sleeve into the jack, and place the rectangular block in the rectangular groove. The rectangular block and the rectangular groove cooperate with each other to prevent the valve from rotating. After the two U-shaped plates are both sleeved on the hollow seat, the two U-shaped plates are connected by bolts and nuts. At this time, under the restriction of the U-shaped plate, the rectangular block is restricted in the rectangular groove to complete the assembly of the valve and the hollow seat. Compared with the method of processing the screw holes for installing the valve on the hollow seat, it avoids the situation of replacing the entire hollow seat due to damage of the screw holes, thereby reducing the waste of resources.

[0012] 2. When connecting the bolt and the nut, make the bolt pass through the corresponding round holes on the support ring and the ear plate. When the bolt and the nut are connected, the structure formed by the support ring and the short rod is between the bolt head and one ear plate. Under the joint support of the short rod and the support ring, there is a distance between the bolt head and one ear plate. When the bolt and the nut cannot be separated normally due to moisture or other reasons, the gap between the support ring and the ear plate can be used to cut off the bolt rod to separate the two interconnected ear plates.
