Description

Technical Field

[0001] This utility model relates to the technical field of blank cooling equipment, and in particular to a cooling treatment device for casting blanks. Background Technology

[0002] When a casting blank is removed from the mold, it needs to be cooled. Currently, most casting blanks are cooled by water immersion. However, the coolant is prone to uneven flow during the cooling process, resulting in inconsistent cooling rates in different parts of the casting blank and reducing product quality. Therefore, a cooling device for casting blanks is proposed to solve this problem. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0004] A cooling treatment device for casting blanks, comprising:

[0005] Water tank;

[0006] A flow guiding unit symmetrically arranged on the inner wall of a water tank includes a distribution plate fixedly connected to the inner wall of the water tank. The distribution plate has a flow channel inside and multiple sets of clamping plates are integrally arranged along the length of the distribution plate. Multiple sets of water outlet holes communicating with the flow channel are opened on the clamping plates.

[0007] Multiple sets of baffles are vertically arranged between the two sets of flow guiding units, and the two ends of the baffles are engaged with the card plates.

[0008] The above technical solution divides the space inside the water tank into multiple chambers using baffles, allowing for flexible adjustment of the placement space and improving the applicability of the cooling device. After the coolant flows out from the outlet of the distribution plate, it is blocked by the baffles, forcing the coolant to flow separately along the areas on both sides of the baffles, forming a specific coolant flow field that covers all parts of the casting blank. During this process, the coolant continuously exchanges heat with the casting blank, carrying away its heat and preventing localized insufficient or excessive cooling due to poor coolant flow. This ensures that the temperature of the entire blank decreases uniformly during the cooling process, effectively improving product quality, reducing internal stress and deformation caused by uneven cooling, and lowering the scrap rate.

[0009] As an improvement to the above technical solution, a filter screen is provided inside the water tank and below the distribution plate.

[0010] As an improvement to the above technical solution, a connecting pipe is provided between the bottom of the water tank and the distribution plate, and a water pump is installed on the connecting pipe.

[0011] As an improvement to the above technical solution, both ends of the partition are provided with limiting grooves that are adapted to the card plate.

[0012] As an improvement to the above technical solution, a rubber pad is provided on the partition.

[0013] The beneficial effects of this utility model are:

[0014] The space inside the water tank is divided into multiple chambers by baffles, allowing for flexible adjustment of the placement space and improving the applicability of the cooling device. After the coolant flows out of the outlet holes of the distribution plate, it is blocked by the baffles, forcing the coolant to flow separately along the areas on both sides of the baffles, forming a specific coolant flow field that covers all parts of the casting blank. During this process, the coolant continuously exchanges heat with the casting blank, carrying away the heat from the casting blank. This avoids localized insufficient or excessive cooling caused by poor coolant flow, ensuring that the temperature of the entire blank drops uniformly during the cooling process, effectively improving product quality, reducing internal stress and deformation caused by uneven cooling, and lowering the scrap rate.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] A cooling treatment device for casting blanks, comprising:

[0021] Water tank 10;

[0022] A flow guiding unit is symmetrically arranged on the inner wall of the water tank 10. The flow guiding unit includes a distribution plate 20 fixedly connected to the inner wall of the water tank 10. The distribution plate 20 has a flow channel inside. Multiple sets of clamping plates 21 are integrally arranged along the length direction of the distribution plate 20. Multiple sets of water outlet holes 22 communicating with the flow channel are opened on the clamping plates 21.

[0023] Multiple sets of baffles 40 are vertically arranged between the two sets of flow guiding units, and the two ends of the baffles 40 are engaged with the clamping plate 21.

[0024] Specifically, a portion of the coolant is injected into the water tank 10, and then the coolant is conveyed to the distribution plate 20. As the coolant flows within the flow channel, it flows out through multiple sets of water outlets 22 on the baffle plate 21, causing the coolant to be sprayed into the water tank 10 for preliminary cooling of the casting blanks inside. Multiple sets of baffles 40 divide the space inside the water tank 10 into multiple chambers. These chambers not only provide dedicated placement areas for the casting blanks, but also allow for flexible adjustment of the placement space according to the shape, size, and quantity of the casting blanks, improving the applicability of the cooling device. After the coolant flows out from the water outlets 22 of the distribution plate 20, it will... The coolant is forced to flow along the areas on both sides of the baffle 40, forming a specific coolant flow field that covers all parts of the casting blank. During this process, the coolant continuously exchanges heat with the casting blank, carrying away its heat and preventing localized insufficient or excessive cooling due to poor coolant flow. This ensures a uniform temperature drop throughout the blank, effectively improving product quality, reducing internal stress and deformation caused by uneven cooling, and lowering the scrap rate. Furthermore, increased coolant flow around the blank allows for a more uniform temperature distribution within the tank. As the coolant absorbs heat from the blank, its temperature rises, but rapid flow allows heat to diffuse over a wider area, preventing localized overheating and maintaining stable operation of the entire cooling system.

[0025] In one embodiment, a filter screen 30 is provided inside the water tank 10 and below the distribution plate 20, and a connecting pipe 23 is provided between the bottom of the water tank 10 and the distribution plate 20, and a water pump is installed on the connecting pipe 23;

[0026] Specifically, refer to Figure 1 When the water pump is started, as the coolant cools the casting blank and flows downwards, it passes through the filter screen 30. The filter screen 30 can effectively intercept impurities washed down from the surface of the casting blank during the cooling process, preventing these impurities from entering the connecting pipe 23 and damaging the water pump or affecting the circulation effect of the coolant. The filtered coolant gathers at the bottom of the water tank 10, and the coolant at the bottom of the water tank 10 is pumped back into the distribution plate 20 through the connecting pipe 23, forming a circulation flow of coolant.

[0027] In one embodiment, reference Figure 2 as well as Figure 3Both ends of the partition 40 are provided with limiting grooves 41 that are adapted to the card plates. When the partition 40 is installed, the limiting grooves 41 at both ends of the partition 40 are aligned with the card plates 21 at both ends to form a stable connection structure. The limiting grooves 41 of the partition 40 can seal the water outlet holes 22 on the card plate 21. When the coolant cannot flow out from the sealed card plate 21, it will all converge to other unsealed card plates 21. This increases the water output of the water outlet holes 22 on other card plates 21, enhances the convective heat transfer effect, and effectively enhances the cooling effect while improving the structural stability.

[0028] In one embodiment, a rubber pad is provided on the partition 40 to prevent damage to the blank when it collides with the partition 40 during placement.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
