Description

Technical Field

[0001] This invention relates to the field of die casting cooling technology, specifically to a large integrated dual-station cooling device for die castings. Background Technology

[0002] Large, integrated die-cast parts, with their compact structure, high forming efficiency, and excellent mechanical properties, are widely used in the automotive, aerospace, and construction machinery industries. Die-cast parts made from high-strength, lightweight structural aluminum alloys, in particular, have become core components in various fields due to their lightweight and high strength advantages. In the die-casting production process, the cooling stage is a crucial step in ensuring product quality, directly affecting the forming accuracy, internal microstructure uniformity, and subsequent processing performance of the die-cast parts. Insufficient or uneven cooling can easily lead to defects such as deformation, cracks, and shrinkage cavities, reducing the product yield. This is especially true for high-strength, lightweight structural aluminum alloy die-cast parts, where the cooling quality directly determines whether they can fully realize their core advantages of lightweight and high strength.

[0003] Currently, in die-casting production environments, water-cooled pools are commonly used to cool die-cast parts. The core operation involves placing the newly formed die-cast part on a lifting mechanism, which then moves it into the water-cooled pool. The cooling water's heat exchange effect cools the part. While this method is simple and inexpensive, meeting basic cooling requirements, it reveals several unavoidable technical flaws in cooling large, integrated die-cast parts, especially large, high-strength, lightweight structural aluminum alloy die-cast parts, severely impacting cooling efficiency and product quality.

[0004] The primary problem is uneven cooling. Large, integrated die-cast parts are bulky and complex in structure, especially high-strength, lightweight structural die-cast aluminum alloy parts. Their structural designs are often more intricate, and the stress requirements are more stringent, demanding higher standards for cooling uniformity. When placed on a lifting mechanism, the area where the die-cast part contacts the lifting mechanism is completely blocked, preventing sufficient contact with the cooling water and hindering heat dissipation. Conversely, the unblocked areas of the die-cast part have full contact with the cooling water and cool down faster. This results in uneven temperature drops across different parts of the die-cast part, generating thermal stress and leading to quality problems such as deformation and cracking. This fails to meet the stringent requirements for cooling uniformity in large die-cast parts, especially high-strength, lightweight structural die-cast aluminum alloy parts.

[0005] Secondly, cooling efficiency is difficult to guarantee. When high-temperature die-cast parts are placed in a water-cooling tank, a vapor film instantly forms on their surface. This vapor film isolates the die-cast part from the cooling water, significantly reducing heat exchange efficiency, hindering heat transfer, slowing down the cooling rate of the die-cast part, prolonging the cooling cycle, and affecting overall production efficiency. Simultaneously, the presence of the vapor film further exacerbates cooling unevenness, preventing effective cooling of localized areas on the die-cast part's surface, further increasing the product defect rate. This problem is more pronounced for high-strength, lightweight structural die-cast aluminum alloy parts, easily leading to uneven internal structure and failure to achieve the designed mechanical properties. Summary of the Invention

[0006] This invention provides a dual-station cooling device for large integrated die-casting parts to solve the problem that existing cooling devices cannot efficiently and uniformly cool die-casting parts.

[0007] The present invention provides a dual-station cooling device for large integrated die-casting parts, which adopts the following technical solution: A dual-station cooling device for large integrated die-cast parts, comprising a cooling pool and a clamping assembly.

[0008] The cooling pool contains a cooling medium, and a circulating cooling mechanism is provided outside the cooling pool to circulate and cool the cooling medium within the cooling pool. The cooling pool has at least two cooling stations. At least two sets of clamping assemblies are provided, one clamping assembly at each cooling station. Each clamping assembly includes a first clamping part and a second clamping part, which together clamp the die-casting part. The first and second clamping parts can maintain the clamping state of the die-casting part and slowly guide it into the cooling pool. Both the first and second clamping parts can intermittently change the position of the clamped die-casting part. The second clamping part can also disturb the cooling medium during the entry of the die-casting part into the cooling pool, causing it to rapidly impact the position of the die-casting part in contact with the cooling medium.

[0009] Furthermore, the clamping assembly also includes a sliding bracket and a driving member. The sliding bracket is vertically disposed on the side wall of the cooling pool, and the driving member is used to drive the sliding bracket to slide in the vertical direction. The first clamping part and the second clamping part are both disposed on the sliding bracket.

[0010] Furthermore, the first clamping part includes a swing rod, a telescopic contact rod, and a first driving cylinder. One end of the swing rod is hinged to the sliding bracket. Two sets of telescopic contact rods are provided, with the two sets of telescopic contact rods spaced apart. The two sets of telescopic contact rods can alternately extend and retract when clamping the die-casting part. One end of the first driving cylinder is hinged to the sliding bracket, and the other end of the first driving cylinder is hinged to the middle of the swing rod.

[0011] Furthermore, the second clamping part includes a mounting plate and a support plate. The mounting plate is obliquely fixed on the sliding bracket, and the support plate is disposed on the mounting plate. The support plate is provided with a plurality of support rods, which can position and support the die-cast part.

[0012] Furthermore, the support plate includes multiple rectangular frames, the size of which decreases or increases progressively, and the multiple rectangular frames are sequentially nested into a plate-like structure; multiple second drive cylinders are provided between each rectangular frame and the mounting plate, and the multiple second drive cylinders provided on the same rectangular frame can extend and retract synchronously; multiple support rods are provided on each rectangular frame.

[0013] Furthermore, a spoiler is provided on the upper surface of the edge of each rectangular frame, a hinge shaft is provided in the middle of the lower surface of the spoiler, and an arc groove with an upward opening is provided on the upper surface of the rectangular frame, with the hinge shaft rotatably disposed in the arc groove; a plurality of first elastic elements are provided between the lower surface of the spoiler and the upper surface of the rectangular frame, the first elastic elements being used to maintain a stable posture when the distance between the rectangular frame and the mounting plate changes.

[0014] Furthermore, a limiting member is provided between the spoilers installed on the parallel edges of two adjacent rectangular frames. The limiting member is used to guide the spoilers to swing relative to the rectangular frames when the distance between the two adjacent rectangular frames and the mounting plate changes inconsistently.

[0015] Furthermore, the limiting member includes a first limiting groove, a second limiting groove, a limiting block, and a second elastic member. The first limiting groove is disposed on the inner side of one of two adjacent parallel spoilers, and the second limiting groove is disposed on the outer side of one of two adjacent parallel spoilers. One end of the limiting block is slidably disposed in the first limiting groove, and the other end of the limiting block is tapered, allowing the tapered end of the limiting block to enter the second limiting groove. The second elastic member is disposed between the first limiting groove and the limiting block, and is used to push the limiting block outward from the first limiting groove.

[0016] Furthermore, the elastic potential energy of the first elastic element is less than that of the second elastic element, and the pushing force of the first elastic element on the baffle is greater than the resistance of the baffle when the cooling medium moves.

[0017] Furthermore, the sliding bracket is equipped with a vision sensor and a controller. The vision sensor is used to detect the position where the die-cast part contacts the cooling medium. The vision sensor can also simultaneously detect the shape and contour of the die-cast part at the position where it contacts the cooling medium. The controller can receive and analyze the data detected by the vision sensor. The controller can adjust a portion of the second drive cylinder based on the received data.

[0018] The beneficial effects of this invention are as follows: This invention provides a large-scale integrated dual-station cooling device for die-cast parts, comprising a cooling pool and clamping components. When it is necessary to cool a die-cast part made from high-strength, lightweight structural aluminum alloy, a cooling medium is first injected into the cooling pool. The circulating cooling mechanism installed on the cooling pool can circulate and cool the cooling medium, ensuring that the cooling medium remains at a low temperature. The number of clamping components is adjusted according to the number of cooling stations inside the cooling pool to ensure a one-to-one correspondence, allowing the die-cast part to be clamped by the first clamping component. The first clamping part and the second clamping part clamp together, which can maintain the clamping state of the die casting and slowly enter the cooling pool. Both the first clamping part and the second clamping part can intermittently change the position of the die casting, thereby avoiding the inefficiency of cooling the die casting in the clamping position. When the high temperature die casting comes into contact with the cooling medium, a vapor film will form on the surface of the die casting. At this time, the second clamping part can disturb the cooling medium and quickly impact the position where the vapor film is formed. Under the impact of the cooling medium, the vapor film can quickly dissipate, thereby improving the cooling efficiency of the die casting. Attached Figure Description

[0025] like Figures 1 to 10 As shown in the figure, an embodiment of the present invention provides a dual-station cooling device for large integrated die-cast parts, which includes a cooling pool 110 and a clamping assembly.

[0026] The cooling pool 110 stores a cooling medium inside, and a circulating cooling mechanism 120 is provided outside the cooling pool 110. The circulating cooling mechanism 120 is used to circulate and cool the cooling medium inside the cooling pool 110. The cooling pool 110 has at least two cooling stations inside. In this embodiment, the cooling medium is water. The circulating cooling mechanism 120 includes a circulating pump and a cooling cylinder. A cooling compressor is provided inside the cooling cylinder. The circulating pump can transport the cooling medium inside the cooling pool 110 to the cooling cylinder. The circulating pump can also transport the cooling medium inside the cooling cylinder back to the cooling pool 110. The position where the cooling medium is extracted from the cooling pool 110 and the position where it is transported back to the cooling pool 110 are on opposite sides of the cooling pool 110.

[0027] At least two sets of clamping components are provided, with one clamping component at each cooling station. Furthermore, the number of cooling stations can be determined comprehensively based on the size of the cooling pool 110, the power of the circulating pump, and the cooling efficiency of the cooling cylinder. The number of clamping components is adjusted according to the number of cooling stations to ensure that the clamping components and cooling stations are in a one-to-one correspondence.

[0028] The clamping assembly includes a first clamping part and a second clamping part, which together clamp the die-casting part. Initially, the first and second clamping parts are separated, facilitating the placement of the die-casting part between them. After clamping the die-casting part, the first and second clamping parts maintain the clamped state and slowly enter the cooling pool 110. During this process, the positions of the clamping parts intermittently change, thus preventing the die-casting part from being unable to be efficiently cooled. The second clamping part can also agitate the cooling medium during the entry of the die-casting part into the cooling pool 110, rapidly impacting the position of the die-casting part in contact with the cooling medium. Specifically, when the high-temperature die-casting part comes into contact with the cooling medium, a vapor film forms on the surface of the die-casting part. The second clamping part can agitate the cooling medium to rapidly impact the position of the vapor film on the die-casting part. Under the impact of the cooling medium, the vapor film can dissipate quickly, thereby improving the cooling efficiency of the die-casting part.

[0029] In one embodiment, the clamping assembly further includes a sliding bracket 210 and a driving member. The sliding bracket 210 is vertically disposed on the side wall of the cooling pool 110, and the driving member is used to drive the sliding bracket 210 to slide vertically. In this embodiment, the sliding bracket 210 has a vertical section and a horizontal section, which are fixedly connected to each other, making the sliding bracket 210 form an L-shape, wherein the vertical section can slide vertically. The driving member is a hydraulic cylinder 220, which is vertically disposed and can drive the entire sliding bracket 210 to move vertically, and the horizontal section can completely enter the cooling medium. Further, a first clamping part is disposed on the vertical section, and a second clamping part is disposed on the horizontal section. Under the combined action of the first clamping part and the second clamping part, the die-cast part can be clamped.

[0030] In one embodiment, the first clamping part includes a swing rod 230, a telescopic contact rod 240, and a first drive cylinder 250. One end of the swing rod 230 is hinged to the vertical section of the sliding bracket 210. Multiple telescopic contact rods 240 are provided, which can be divided into two groups. Multiple telescopic contact rods 240 in any group are arranged in a row, with the two groups spaced apart. One end of each telescopic contact rod 240 is fixedly connected to the end of the swing rod 230 away from the vertical section. The length of each telescopic contact rod 240 can be changed. In this embodiment, multiple telescopic contact rods 240 in a group can extend and retract simultaneously. The telescopic contact rods 240 can extend and retract hydraulically or pneumatically. One end of the first drive cylinder 250 is hinged to the vertical section of the sliding bracket 210, and the other end is hinged to the middle of the swing rod 230. When clamping the die-cast part, the first drive cylinder 250 gradually extends, causing the swing rod 230 to swing around the end hinged to the vertical section.

[0031] Furthermore, the swing arm 230 is equipped with an air pump or an oil pump, which can supply air or oil to the telescopic contact rod 240, and can also extract air or oil from the telescopic contact rod 240, thereby changing the length of the telescopic contact rod 240. During the extension of the first drive cylinder 250, multiple telescopic contact rods 240 in one group contact the die-cast part. Subsequently, the lengths of the two groups of telescopic contact rods 240 change alternately, thereby changing the position of the telescopic contact rod 240 in contact with the die-cast part, thus avoiding the situation where the position of the telescopic contact rod 240 in contact with the die-cast part cannot achieve efficient cooling.

[0032] In one embodiment, the second clamping part includes a mounting plate 310 and a support plate 320. The mounting plate 310 is obliquely fixed on the horizontal section of the sliding bracket 210 and is designed to be hollow to facilitate the passage of cooling medium. The support plate 320 is positioned above the mounting plate 310 and has multiple support rods. These support rods can position and support the die-casting part. Under the action of the support rods, the die-casting part is in a state of not contacting the support plate 320, preventing the cooling medium from directly contacting the die-casting part.

[0033] In one embodiment, the support plate 320 includes a plurality of rectangular frames 321, the size of which decreases or increases progressively. The plurality of rectangular frames 321 are sequentially nested into a plate-like structure, and adjacent rectangular frames 321 can move relative to each other. The lower surface of the support plate 320 formed by the plurality of rectangular frames 321 can present a conical structure. In the initial state, the lower surface of the support plate 320 is adjusted to a downwardly convex conical structure. When the sliding bracket 210 gradually enters the cooling medium, the lower surface of the support plate 320 can guide impurities on the surface of the cooling medium, reducing the adhesion of impurities on the surface of the cooling medium to the surface of the die-cast part.

[0034] Furthermore, multiple second drive cylinders 330 are provided between each rectangular frame 321 and the mounting plate 310, and the multiple second drive cylinders 330 provided on the same rectangular frame 321 can extend and retract synchronously; multiple support rods are provided on each rectangular frame 321, and when it is necessary to adjust the shape of the lower surface of the support plate 320, the length of the multiple second drive cylinders 330 installed on a rectangular frame 321 can be adjusted.

[0035] In one embodiment, each rectangular frame 321 has four edges, and a spoiler 340 is provided on the upper surface of each edge. Specifically, a hinge shaft 341 is fixedly provided on the lower surface of the spoiler 340, wherein the extending direction of the hinge shaft 341 is the same as the extending direction of the spoiler 340, and the hinge shaft 341 is located at the middle of the width direction of the spoiler 340. An upward-opening arc groove is provided on the upper surface of the edge of the rectangular frame 321, and the hinge shaft 341 is rotatably disposed in the arc groove. A plurality of first elastic elements are provided between the lower surface of the spoiler 340 and the upper surface of the rectangular frame 321. In this embodiment, the first elastic elements are first springs 350, and the extending direction of the first springs 350 is perpendicular to the lower surface of the spoiler 340 and the upper surface of the rectangular frame 321. In the initial state, neither the mounting plate 310 nor the support plate 320 is in contact with the cooling medium. Under the action of the plurality of first springs 350, the lower surface of the spoiler 340 is in a state parallel to the upper surface of the rectangular frame 321.

[0036] As is easy to understand, since the mounting plate 310 is in an inclined state and the support plate 320 is installed above the mounting plate 310, when the die casting is placed on the support plate 320, the first drive cylinder 250 drives the swing rod 230 to gradually approach the support plate 320, so that the telescopic contact rod 240 on the swing rod 230 gradually contacts the surface of the die casting. When the telescopic contact rod 240 stably presses against the die casting, the hydraulic cylinder 220 gradually drives the sliding bracket 210 to move into the cooling medium. Because the die-cast part is in a high-temperature state, when the die-cast part comes into contact with the cooling medium, a vapor film will form on the surface of the die-cast part. At this time, a rectangular frame 321 corresponding to the location where the vapor film is generated in the die-cast part moves up and down relative to the other rectangular frames 321. The baffle 340 installed on the reciprocating rectangular frame 321 can disturb the cooling medium, causing the flow rate of the cooling medium in a local position to increase. Since the cooling medium with increased flow rate is below the location where the vapor film is generated in the die-cast part, the cooling medium with increased flow rate can impact the location where the vapor film is generated in the die-cast part, thereby accelerating the rapid dissipation of the vapor film at that location.

[0037] In one embodiment, if the surface of the die-cast part is irregular, the position of the vapor film is irregular, and the movement of a single rectangular frame 321 cannot quickly impact the vapor film. A limiting member is provided between the baffles 340 installed on the parallel edges of two adjacent rectangular frames 321. The limiting member is used to guide the baffles 340 to swing relative to the rectangular frames 321 when the distance between the two adjacent rectangular frames 321 and the mounting plate 310 changes.

[0038] Specifically, taking the lower surface of the die-cast part as a concave surface as an example, when the die-cast part comes into contact with the cooling medium, a vapor film will be generated at the position where the die-cast part comes into contact with the cooling medium. At this time, at least two adjacent rectangular frames 321 are adjusted to move relative to the mounting plate 310 at the same time, and the amount of movement of the two adjacent rectangular frames 321 relative to the mounting plate 310 is different, and the amount of movement of the outer rectangular frame 321 is greater than that of the inner rectangular frame 321. Under the action of the limiting component, the baffles 340 installed on the two rectangular frames 321 swing, thereby ensuring that the cooling medium after being disturbed by the baffles 340 can accurately impact the vapor film.

[0039] In one embodiment, the limiting member includes a first limiting groove, a second limiting groove, a limiting block 410, and a second elastic member. The first limiting groove is disposed on the inner side of one of two adjacent parallel spoilers 340, and the second limiting groove is disposed on the outer side of one of two adjacent parallel spoilers 340. One end of the limiting block 410 is slidably disposed in the first limiting groove, and the other end of the limiting block 410 is tapered. The tapered end of the limiting block 410 can enter the second limiting groove. Furthermore, when two adjacent rectangular frames 321 move relative to each other, the limiting block 410 can be squeezed out of the second limiting groove. The second elastic member is disposed between the first limiting groove and the limiting block 410. The second elastic member is used to push the limiting block 410 outward from the first limiting groove. The second elastic member is a second spring 420. In the initial state, the second spring 420 can ensure that the tapered end of the limiting block 410 is in the second limiting groove.

[0040] Furthermore, the elastic potential energy of the first spring 350 is less than that of the second spring 420, and the pushing force of the first spring 350 on the baffle 340 is greater than the resistance of the baffle 340 when the cooling medium moves. For ease of understanding, taking the lower surface of the die-cast part as a concave surface as an example, when the die-cast part contacts the cooling medium, a vapor film will be generated at the contact point. At this time, at least two adjacent rectangular frames 321 are adjusted to move simultaneously relative to the mounting plate 310, and the amount of movement of the two adjacent rectangular frames 321 relative to the mounting plate 310 is different; specifically, the movement of the outer rectangular frame 321 is greater than that of the inner rectangular frame 321. Simultaneously, the movement speed of the two rectangular frames 321 is increased or decreased, where the increase or decrease is determined by the clearance on the lower surface of the die-cast part. When the lower surface of the die-cast part is concave, the movement speed of the two rectangular frames 321 is increased simultaneously; conversely, when the lower surface of the die-cast part is convex, the movement speed of the two rectangular frames 321 is decreased simultaneously to prevent the cooling medium from splashing after disturbance.

[0041] Between two moving rectangular frames 321 and other non-moving rectangular frames 321, the limiting block 410 can quickly disengage from the second limiting groove; between two moving rectangular frames 321, the limiting block 410 does not completely disengage from the second limiting groove, and under the action of the limiting block 410, the spoiler 340 swings relative to the rectangular frames 321.

[0042] In one embodiment, a vision sensor and a controller are provided on the sliding bracket 210. The vision sensor is used to detect the position of the die-casting part in contact with the cooling medium, and can also simultaneously detect the shape and contour of the die-casting part at the position of contact with the cooling medium. The controller can receive and analyze the data detected by the vision sensor, and can adjust part of the second drive cylinder 330 based on the received data to ensure that the cooling medium disturbed by the baffle 340 accurately impacts the generated vapor film.

[0043] In one embodiment, when the die-casting is fully immersed in the cooling medium, the controller can control multiple second drive cylinders 330 to extend and retract, causing multiple rectangular frames 321 to reciprocate, making the cooling medium turbulent and improving the cooling efficiency of the die-casting.

[0044] In one embodiment, an air blowing plate 130 is provided above the side wall of the cooling pool 110. The air blowing plate 130 is provided with multiple air blowing nozzles. After the die casting is cooled down and removed from the cooling medium, the multiple air blowing nozzles blow air onto the die casting at the same time. The air blowing nozzles can clean the cooling medium and impurities remaining on the surface of the die casting, thereby improving the cleanliness of the surface of the die casting after cooling.

[0045] In one embodiment, the upper surface of the spoiler 340 is configured to be wavy or folded to accommodate different profiles of the die casting.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
