DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] See also Figure 1 to Figure 5 , a nonferrous metal casting mold with a mold cavity forming cooling function, comprising:

[0029] A workbench 1, on which a lower mold 11 and an upper mold 12 are installed, wherein mold cavities are provided inside the lower mold 11 and the upper mold 12, and a cooling mold 13 is slidably connected to the outer surfaces of the lower mold 11 and the upper mold 12;

[0030] A cooling assembly is installed on the workbench 1 and is connected to the lower mold 11, the upper mold 12, and the cooling mold 13, respectively, and is used to cool the lower mold 11, the upper mold 12, and the cooling mold 13, respectively;

[0031] The lifting assembly 3 is slidably connected to the workbench 1 and is respectively connected to the cooling mold 13 and the cooling assembly, and is used to adjust the positions of the cooling mold 13 and the cooling assembly;

[0032] The sliding assembly 4 is rotatably connected to the workbench 1 and connected to the lower mold 11, and is used to drive the lower mold 11 and the upper mold 12 to slide;

[0033] The rotating assembly 5 is connected to the lifting assembly 3 at one end and to the sliding assembly 4 at the other end, and is used to cooperate with the lifting assembly 3 to realize the sliding and stopping of the sliding assembly 4, thereby realizing the cooling mold 13 to cool the upper and lower surfaces of the lower mold 11 and the upper mold 12 in an orderly manner.

[0034] In an embodiment of the present invention, when cooling the upper mold 12 and the lower mold 11, the cooling mold 13 is driven to descend by the lifting assembly 3. With the cooperation of the lifting assembly 3 and the sliding assembly 4, the upper mold 12 and the lower mold 11 will slide to and stay directly below the cooling mold 13, so that the cooling mold 13 can slide to the outer surface of the upper mold 12 and the lower mold 11 for cooling. The upper surface of the upper mold 12 and the lower mold 11 can be cooled first, thereby avoiding the situation where the temperature of the upper part of the mold is higher than the temperature of the lower part, causing uneven cooling, and overcoming the technical prejudice in the prior art that the upper and lower parts of the mold need to be cooled equally.

[0035] In one embodiment of the present invention, Figure 1 As shown, the cooling assembly includes:

[0036] A cooling pool 21 is installed on the workbench 1 and has a piston plate slidably connected therein;

[0037] A slide rod 22 is slidably connected in the cooling pool 21, one end of which is connected to the piston plate, and the other end of which is fixed with a transverse plate 221;

[0038] The cooling through pipe 23 is spirally opened inside the lower mold 11, the upper mold 12 and the cooling mold 13. The two ends of the cooling through pipe 23 are connected to the cooling pool 21 through the water inlet pipe 24 and the water outlet pipe 25 respectively. The cooling through pipes 23 at the contact end surfaces of the upper mold 12 and the cooling mold 13 are engaged with each other, and a high-temperature resistant sealing ring is installed in the cooling through pipe 23 at the contact end surfaces.

[0039] In this embodiment, when casting non-ferrous metals, the upper mold 12 and the lower mold 11 are fixed by bolts so that the mold cavities inside the upper mold 12 and the lower mold 11 are connected, and the molten metal is introduced into the mold cavity through the casting hole by external high-pressure equipment for casting operation.

[0040] When cooling the mold, an external water cooler can be used to cool the cooling water in the cooling pool 21. When the lifting assembly 3 is turned on, the horizontal plate 221 will drive the slide bar 22 to slide downward in the cooling pool 21 under the action of the lifting assembly 3. When the slide bar 22 slides, it will drive the piston plate at its end to slide downward in the cooling pool 21. At this time, due to the reduction of the space in the cooling pool 21, the cooling water in the cooling pool 21 will flow into the cooling pipe 23 in the lower mold 11 and the cooling mold 13 through the water inlet pipe 24 under the extrusion of the piston plate. And the cooling water in the cooling pipe 23 on the lower mold 11 will flow into the cooling pipe 23 in the upper mold 12, thereby realizing the cooling of the upper mold 12, the lower mold 11, and the cooling mold 13.

[0041] When the lifting assembly 3 descends, it will drive the cooling mold 13 to descend synchronously, and the upper mold 12 and the lower mold 11 will slide to the bottom of the cooling mold 13 under the action of the sliding assembly 4, until the cooling mold 13 slides to the surface of the upper mold 12 and the lower mold 11 as a whole (such as Figure 1 Under the action of the cooling assembly, the upper mold 12 and the lower mold 11 are internally cooled by the cooling water in the cooling pipe 23 therein, and are externally cooled by the cooling mold 13, thereby increasing the cooling efficiency.

[0042] Due to the limited space of the cooling pool 21, when the slide rod 22 drives the piston plate to slide to the bottom of the cooling pool 21, the cooling water in the cooling pool 21 is completely discharged, and the cooling is completed, which prevents the non-ferrous metal from cooling for too long, which may cause coarse grains and reduce mechanical properties, or may produce greater shrinkage stress, causing deformation or cracks. In addition, in terms of production efficiency, non-ferrous metal casting is usually used for mass production, such as automotive parts. Too long cooling time will affect production capacity and increase costs. At the same time, long-term cooling at high temperature may accelerate thermal fatigue of the mold and affect the life of the mold.

[0043] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the lifting assembly 3 includes:

[0044] The bracket 31 is fixed on the workbench 1, and a cylinder 32 is installed on the side;

[0045] The telescopic rod 321 has one end connected to the output end of the cylinder 32, and the other end connected to the lifting frame 33. The cooling mold 13 is fixed to the side of the lifting frame 33, and the lifting frame 33 is connected to the horizontal plate 221;

[0046] The slide rail 35 is connected to the surface of the workbench 1 , and a slide frame 34 is slidably connected to the slide rail 35 . The lower mold 11 is installed on the slide frame 34 , and the upper mold 12 is connected to the upper part of the lower mold 11 by bolts.

[0047] In this embodiment, the cylinder 32 is turned on, and the output end of the cylinder 32 will drive the lifting frame 33 to slide downward through the telescopic rod 321, so that the lifting frame 33 will drive the cooling mold 13 on its side to slide downward synchronously until the cooling mold 13 completely slides to the surface of the upper mold 12 and the lower mold 11, so that the outer surfaces of the upper mold 12 and the lower mold 11 will be cooled under the action of the cooling mold 13.

[0048] In one embodiment of the present invention, Figure 1 As shown, the sliding assembly 4 includes:

[0049] A first rotating shaft 41 is rotatably connected to the workbench 1;

[0050] The second rotating shaft 42 is rotatably connected to the workbench 1, and the surface is connected to the first rotating shaft 41 through a transmission belt 45;

[0051] A gear 43 connected to the second rotating shaft 42;

[0052] The rack 44 is fixed on the surface of the sliding frame 34 and is meshedly connected with the gear 43 .

[0053] In this embodiment, when the lifting frame 33 is lifted, the first rotating shaft 41 drives the second rotating shaft 42 to rotate through the transmission belt 45, and the second rotating shaft 42 drives the sliding frame 34 to slide on the surface of the workbench 1 through the connection between the gear 43 and the rack 44. Specifically, when the lifting frame 33 drives the cooling mold 13 to slide downward, the sliding frame 34 slides toward the cooling pool 21, so that the sliding frame 34 drives the lower mold 11 and the upper mold 12 on its surface to slide to the right below the cooling mold 13, so that the cooling mold 13 can cool the outer surface of the lower mold 11 and the upper mold 12 as a whole. When the lifting frame 33 drives the cooling mold 13 to slide upward, conversely, the sliding frame 34 will drive the lower mold 11 and the upper mold 12 on its surface to slide to the end position close to the workbench 1, so that after the lower mold 11 and the upper mold 12 are cooled, it is convenient to demold the lower mold 11 and the upper mold 12, so that the mold is not restricted by the position of the cooling mold 13 when demolding, so that it is maximally convenient to use tools to demold the mold, which has the characteristics of easy demolding and high demolding safety.

[0054] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the rotating assembly 5 includes:

[0055] The sliding plate 51 is connected to the two ends of the lifting frame 33 and has a semicircular groove 53 on its surface;

[0056] The vertical groove 52 is formed on the sliding plate 51 and communicates with both ends of the semicircular groove 53;

[0057] The rotating frame 54 is installed at the end of the first rotating shaft 41 away from the rotating frame 43, and the radius of the semicircular groove 53 is equal to the length of the rotating frame 54;

[0058] The sliding shaft 55 is fixed to the end of the rotating frame 54 , and its surface is slidably connected inside the vertical groove 52 and the semicircular groove 53 .

[0059] In this embodiment, when cooling the upper mold 12 and the lower mold 11, the cylinder 32 is turned on to make the cooling mold 13 slide downward. When the lifting frame 33 slides downward, it will drive the sliding plates 51 at both ends thereof to descend synchronously. When the sliding plate 51 slides downward, it will drive the lower part of the vertical groove 52 on its surface to slide on the surface of the sliding shaft 55 until the sliding shaft 55 slides into the semicircular groove 53. When the sliding plate 51 continues to slide downward, the rotating frame 54 will drive the first rotating shaft 41 to rotate counterclockwise on the workbench 1 under the action of the semicircular groove 53 and the sliding shaft 55.

[0060] When the sliding shaft 55 slides to the midpoint of the semicircular groove 53, the rotating frame 54 rotates to a horizontal position because the radius of the semicircular groove 53 is equal to the length of the rotating frame 54. When the sliding plate 51 continues to drive the vertical groove 52 and the semicircular groove 53 to slide downward, the sliding shaft 55 will continue to slide in the semicircular groove 53. When the sliding shaft 55 slides out of the upper end of the semicircular groove 53, the sliding shaft 55 will slide to the upper part of the vertical groove 52 (such as Figure 2 At this time, the rotating frame 54 drives the sliding shaft 55 to rotate to the lowest point, and then the cooling mold 13 slides downward, the sliding shaft 55 only slides in the upper part of the vertical groove 52, and the rotating frame 54 does not continue to rotate.

[0061] Therefore, when the cooling mold 13 slides downward, the sliding shaft 55 rotates counterclockwise from the highest point to the lowest point, so that the rotating frame 54 will drive the first rotating shaft 41 to rotate 180 degrees counterclockwise on the fixed frame 41, and the first rotating shaft 41 will drive the second rotating shaft 42 to rotate synchronously on the workbench 1 through the transmission belt 45, and then the second rotating shaft 42 will drive the sliding frame 34 to slide toward the bottom of the cooling mold 13 on the surface of the workbench 1 through the connection between the gear 43 and the rack 44, until the cooling mold 13 slides to the position directly below the upper mold 12 and the lower mold 11, at this time, the sliding shaft 55 slides to the upper part of the vertical groove 52, and then the cooling mold 13 will slide downward on the surface of the upper mold 12 and the lower mold 11, while the positions of the upper mold 12 and the lower mold 11 remain unchanged, and then the upper surface of the upper mold 12 and the lower mold 11 can be cooled first, thereby avoiding the situation where the temperature of the upper part of the mold is higher than the temperature of the lower part, causing uneven cooling, and overcoming the technical prejudice of the prior art that the upper and lower parts of the mold need to be cooled equally.

[0062] When demolding the upper mold 12 and the lower mold 11, the cylinder 32 is turned on, so that the lifting frame 33 drives the cooling mold 13 to rise, so that the cooling mold 13 slides upward to the surface that is separated from the upper mold 12 and the lower mold 11. Contrary to the above working process, the sliding shaft 55 will rotate clockwise from the lowest point to the highest point, so that the rotating frame 54 will drive the first rotating shaft 41 to rotate 180 degrees in the opposite direction on the fixed frame 41, and the second rotating shaft 42 will drive the sliding frame 34 to slide on the surface of the workbench 1 toward the end of the workbench 1 through the connection of the gear 43 and the rack 44, so that when demolding the mold, it is not restricted by the position of the cooling mold 13, and has the characteristics of easy demolding and high demolding safety.

[0063] The working principle of the present invention is: when cooling the upper mold 12 and the lower mold 11, the cylinder 32 is turned on to make the cooling mold 13 slide downward. Under the action of the sliding assembly 4, the sliding frame 34 will drive the upper mold 12 and the lower mold 11 to slide to the left to stay just below the cooling mold 13, so that the cooling mold 13 will slide downward on the surface of the upper mold 12 and the lower mold 11, and then the upper surface of the upper mold 12 and the lower mold 11 can be cooled first, avoiding the situation that the temperature of the upper part of the mold is higher than the temperature of the lower part, causing uneven cooling, overcoming the technical prejudice of the prior art that the upper and lower parts of the mold need to be cooled equally, and improving the quality of non-ferrous metal casting.
