Description

Technical Field

[0001] This invention relates to the field of mold cooling technology, and in particular to a high-speed rotating flow cooling device. Background Technology

[0002] In mold cooling structures, where steel thickness is limited and water channel holes cannot be designed too large, the market often uses copper pipe water-flushing or sloping cross-flow water-flushing designs when the water channel holes are extremely small. Copper pipe water-flushing requires inlet and outlet holes, and the copper pipe needs to be installed within mating holes. The water flow rate is not fast enough, resulting in poor cooling effect. Sloping cross-flow water-flushing requires drilling cross-holes, and with angled drilling, the machining risk of angled water-flushing is high, and the machining cost is also high. Therefore, a high-speed rotating flow cooling device is needed, which has the advantages of low risk, low machining equipment cost, and good cooling effect. Summary of the Invention

[0003] In order to overcome the shortcomings of poor cooling effect of molds with limited steel thickness in the prior art, the present invention provides a high-speed rotating flow cooling device. It only requires the design of a water passage hole to allow the water in the inner hole to flow rapidly, thereby achieving the effect of quickly removing heat and achieving good cooling effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-speed rotating flow cooling device includes a cooling plate and a conveying shaft. The cooling plate is provided with staggered and interconnected water passage holes and cooling holes. The conveying shaft is disposed in the cooling holes and rotatably connected to the cooling holes. A water wheel is provided at one end of the conveying shaft near the water passage hole. Part of the structure of the water wheel is disposed in the water passage hole. A water guide hole is provided axially inside the conveying shaft. Both ends of the water guide hole are connected to the cooling holes. A spiral structure is provided on the outer wall of the conveying shaft.

[0006] In the above technical solution, only one water passage hole needs to be designed. The water flow in the water passage hole can drive the water wheel and conveyor shaft to rotate. The spiral structure on the conveyor shaft can carry the cooling water in the water passage hole into the cooling hole to cool the cooling plate. Then, the cooling water flows back to the water passage hole through the guide hole and then flows away through the water passage hole again. During the water flow process, the above cooling device can rotate at high speed, which accelerates the flow and removes heat quickly, resulting in good cooling effect. The water channel is a straight hole design, which is convenient to process and delivers quickly. The processing cost is low, and the installation is convenient. It can be installed from the front, and the water channel only needs to pass through a single water channel, which is simple to process. The effect is even more significant under high-speed and high-pressure water flow. The cooling water in the cooling hole can also enter through the guide hole first and then exit through the spiral structure.

[0007] Preferably, the cooling holes are multiple, arranged side-by-side along the axial direction of the water passage holes, with each cooling hole corresponding to a different conveyor shaft. This structure allows for simultaneous cooling using multiple cooling holes, resulting in a more uniform cooling effect across the entire cooling plate.

[0008] Preferably, the cooling holes include fine holes and coarse holes, with the diameter of the coarse holes being larger than that of the fine holes. A spiral structure is disposed within the fine holes, and a waterwheel is disposed within and adapted to the coarse holes. This structure can increase the lever arm of the torque acting on the blades, thereby increasing the torque.

[0009] Preferably, the waterwheel includes a spindle and several blades, with the blades arranged circumferentially along the spindle.

[0010] Preferably, the blade has a notch on the side near the spindle at its end. This structure facilitates the flow of cooling water and reduces resistance.

[0011] Preferably, a partition plate is provided between two adjacent blades, the partition plate being perpendicular to the blades and intersecting the outer contour line of the water passage hole. This structure can separate the water inlet and outlet ends within the cooling hole, preventing heated cooling water from repeatedly entering the cooling hole and affecting the cooling effect, while the cooling water at the outlet end flows directly away through the water passage hole.

[0012] Preferably, the lower portion of the cooling hole overlaps with the water passage hole. This structure allows the upper portion of the cooling water to directly enter the rear conveyor shaft position to cool the rear cooling hole.

[0013] Preferably, a water guide sleeve is provided inside the water passage hole, positioned between two adjacent water wheels. The water guide sleeve has a first water guide groove and a second water guide groove that are isolated from each other and spirally arranged. The inlet of the first water guide groove is located above the inlet of the second water guide groove, and the outlet of the first water guide groove is located below the outlet of the second water guide groove. This structure allows the cooling water in the upper and lower layers of the water passage hole to be switched, enabling more of the cooler cooling water that did not enter the previous cooling hole to enter the next cooling hole, while reducing the amount of cooling water flowing out of the previous cooling hole from entering the next, thus increasing the cooling effect of subsequent cooling holes and resulting in a more uniform overall cooling effect of the cooling plate.

[0014] The beneficial effects of this invention are: (1) During the flow of cooling water, it can rotate at high speed, which accelerates the flow, removes heat quickly, and has a good cooling effect. The effect is even more significant under high-speed and high-pressure water flow; (2) The water channel is designed with straight holes, which is convenient to process and deliver quickly. The processing cost is low, and the installation is convenient. It is installed from the front, and only one water channel needs to pass through the water channel, which is simple to process; (3) The water guide sleeve can increase the cooling effect of the cooling holes behind it, making the overall cooling effect of the cooling plate more uniform.

Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] like Figure 1 and Figure 2 As shown, a high-speed rotating flow cooling device includes a cooling plate 1 and a conveyor shaft 2. The cooling plate 1 has vertically arranged and interconnected water passage holes 1.1 and cooling holes 1.2. Multiple cooling holes 1.2 are arranged side-by-side along the axial direction of the water passage holes 1.1. The conveyor shaft 2 corresponds one-to-one with each cooling hole 1.2. The conveyor shaft 2 is disposed within and rotatably connected to the cooling holes 1.2. A water wheel 3 is provided at one end of the conveyor shaft 2 near the water passage hole 1.1, and part of the structure of the water wheel 3 is disposed within the water passage hole 1.1. A water guide hole 2.1 is provided axially inside the conveyor shaft 2, with both ends of the water guide hole 2.1 communicating with the cooling holes 1.2. A spiral structure 4 is provided on the outer wall of the conveyor shaft 2. The cooling holes 1.2 include fine holes and coarse holes, with the coarse hole diameter larger than the fine hole diameter. The spiral structure 4 is disposed within the fine hole, and the water wheel 3 is disposed within and adapted to the coarse hole. The waterwheel 3 includes a spindle 3.1 and several blades 3.2, which are evenly arranged around the spindle 3.1. The ends of the blades 3.2 are provided with notches on the side near the spindle 3.1.

[0022] In the above technical solution, only one water passage hole 1.1 needs to be designed. The water flow in the water passage hole 1.1 can drive the water wheel 3 and the conveyor shaft 2 to rotate. The spiral structure 4 on the conveyor shaft 2 can carry the cooling water in the water passage hole 1.1 into the cooling hole 1.2 to cool the cooling plate 1. Then the cooling water flows back to the water passage hole 1.1 through the guide hole 2.1 and flows away through the water passage hole 1.1 again. In the process of water flow, the above cooling device can rotate at high speed, which accelerates the flow and removes heat quickly, resulting in good cooling effect. The water channel is a straight hole design, which is convenient to process and deliver quickly. The processing cost is low, and the installation is convenient. It can be installed from the front, and the water channel only needs to pass through a single water channel, which is simple to process. The effect is even more significant under high-speed and high-pressure water flow. The cooling water in the cooling hole 1.2 can also first enter through the guide hole 2.1 and then exit through the spiral structure 4.

[0023] Example 2:

[0024] like Figure 2 and Figure 3 As shown, based on Embodiment 1, a partition plate 5 is provided between two adjacent blades 3.2. The partition plate 5 is perpendicular to the blades 3.2 and intersects the outer contour line of the water passage hole 1.1. The lower part of the cooling hole 1.2 overlaps with the water passage hole 1.1. A water guide sleeve 6 is provided inside the water passage hole 1.1. The water guide sleeve 6 is located between two adjacent water wheel 3s. The water guide sleeve 6 has a first water guide groove 6.1 and a second water guide groove 6.2 that are isolated from each other and spirally arranged. The inlet of the first water guide groove 6.1 is located above the inlet of the second water guide groove 6.2, and the outlet of the first water guide groove 6.1 is located below the outlet of the second water guide groove 6.2.

[0025] The structure allows for the interchange of the upper and lower layers of cooling water within the water passage 1.1. This allows more of the cooler cooling water that did not enter the previous cooling hole 1.2 to enter the next cooling hole 1.2, while less cooling water that exited the previous cooling hole 1.2 enters the next cooling hole 1.2. This increases the cooling effect of subsequent cooling holes 1.2 and results in a more uniform overall cooling effect for the cooling plate 1. The partition plate 5 separates the inlet and outlet ends of the cooling holes 1.2, preventing heated cooling water from repeatedly entering the cooling holes 1.2 and affecting the cooling effect. The cooling water at the outlet end flows directly away through the water passage 1.1.

[0026] The beneficial effects of the present invention are: (1) During the flow of cooling water, it can rotate at high speed, which accelerates the flow and removes heat quickly, resulting in a good cooling effect. The effect is even more significant under high-speed and high-pressure water flow. (2) The water channel is designed with straight holes, which makes it easy to process and deliver quickly. The processing cost is low, and the installation is convenient. It can be installed from the front, and only one water channel needs to pass through the water channel, which is simple to process. (3) The water guide sleeve 6 can increase the cooling effect of the rear cooling holes 1.2, making the overall cooling effect of the cooling plate 1 more uniform.
