[0002] The core refers to a part of the mold that is used to form the internal structure or holes of the workpiece. Compared with other parts in the mold (such as the mold shell), the core is more used to form the internal space or complex structure of the workpiece, and usually requires additional processing steps and cooling measures to ensure processing quality. The fountain cooling device of the core is a cooling system used in mold manufacturing or metal processing. Its design purpose is to effectively cool the core, that is, the part inside the mold used to form the internal structure or holes of the workpiece, by spraying coolant (usually water or other cooling media).
[0003] When cooling the mold, the mold core in the prior art needs to be cooled by spraying cold water in the form of a fountain. However, most of the transport pipes do not have a structure to prevent backflow. When used for a long time, the pressure generated by the backflow may cause deformation or damage, which greatly shortens the service life. Therefore, in view of the above shortcomings, a fountain cooling device for the mold core is proposed. Utility Model Content

[0022] Reference Figures 3 to 5 A diverter column 7 is fixedly connected to the top of the inner wall of the transport pipe 6 to prevent backflow. A semicircular opening 8 is provided at the bottom of the diverter column 7 to facilitate the engagement of the sliding column 14 and the transportation of cold water. A cross 9 is fixedly connected to the top of the diverter column 7 to support a fixed cylinder 10. The bottom side of the cross 9 is fixedly connected to the fixed cylinder 10. An inner cavity 11 is provided inside the fixed cylinder 10 to ensure that the internal structure has sufficient space for activities. A telescopic component is fixedly connected to the top side of the inner wall of the fixed cylinder 10. The telescopic component includes a spring 12. The top side of the spring 12 is fixedly connected to the top side of the inner wall of the fixed cylinder 10. By fixing the spring 12, the spring 12 can be evenly stressed.
[0023] The outer part of the sliding plate 13 is slidably connected to the inner wall of the inner cavity 11, so that the sliding plate 13 can slide vertically, the bottom side of the spring 12 is fixedly connected with the sliding plate 13, the outer part of the sliding plate 13 is slidably connected to the inner wall of the fixed cylinder 10, the bottom side of the telescopic assembly is fixedly connected with a sliding column 14, the outer part of the sliding column 14 is slidably connected to the inner wall of the bottom end of the fixed cylinder 10, so that the sliding column 14 can slide vertically, and the bottom side of the sliding column 14 is fixedly connected with a valve ball 15, and the sliding column 14 is pushed upward by the valve ball 15 under force, and the outer part of the valve ball 15 is slidably connected to the inner wall of the diverter column 7, which is used to limit the valve ball 15 and enable the valve ball 15 to slide vertically.
[0024] Working principle: When we use the fountain cooling device of the mold core, we put the mold on its outside, and then drive the transport pipe 6 to insert it into the interior of the support column 2 through the special-shaped handle 5, and then transport the cold water in through the cold water port 16, and then the cold water will be transported upward through the transport pipe 6. After the cold water touches the semicircular opening 8 opened on the bottom side of the diverter column 7, it will impact the valve ball 15. The impact will push the valve ball 15 to move upward, and then the valve ball 15 can push the sliding column 14, so that the sliding column 14 can push the sliding plate 13 to slide inside the fixed cylinder 10. At this time, the sliding plate 13 will squeeze the spring 12, so that the spring 12 can store elastic potential energy. After the valve ball 15 moves upward, the cold water will be transported upward along the gap between the valve ball 15 and the diverter column 7, and then the cold water will impact the inner wall of the support column 2 to cool it down. After the cold water stops being transported, the valve ball 15 will lose the bottom pressure. At this time, the spring 12 is convenient to give the valve ball 15 a reset force to prevent backflow.
