Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically to an integrated mechanism for cooling and demolding a casting mold. Background Technology

[0002] Casting molds are important tools used in the casting process to obtain the shape of castings. The structural shape of the part is made in advance using other easily formable materials. Then, the mold is placed in a sand mold to form a cavity with the same structural dimensions as the part. A fluid liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the exact same shape and structure as the mold is formed.

[0003] Chinese Patent Publication No. CN220659184U, authorized on March 26, 2024, discloses a novel casting mold, comprising a base plate, a cooling fan, an electric push rod, an upper mold body, a lower mold body, and a liquid guiding hole. A limit slide rod and an L-shaped fixing plate are fixedly connected to the left end of the top of the base plate. A J-shaped protective plate is fixedly connected to the rear side of the L-shaped fixing plate. Moving blocks are fixedly connected to the left sides of both the lower and upper mold bodies. This invention solves the problems of existing casting molds, such as molten iron splashing and burns to workers when molten iron is added, the lack of a buffer structure during mold closing (due to cylinder push), reduced mold lifespan due to prolonged impact, and decreased production efficiency due to the inability to cool down quickly.

[0004] After the casting has cooled and solidified, the casting is usually removed manually by opening the mold. This demolding method is cumbersome, has low demolding efficiency, and the casting that has not cooled completely can easily cause burns to the hands, posing a safety hazard and failing to meet the usage requirements.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The utility model device is equipped with an inlet valve, an upper cooling chamber, a lower cooling chamber, and a drain valve. Coolant is sent into the upper and lower cooling chambers from the inlet valve. The coolant flowing in the upper and lower cooling chambers absorbs the heat conducted from the casting.

The vibrating motor drives the mounting plate to vibrate, and the vibration force is transmitted to the frame through the connecting rod, so that the connection between the frame and the casting resonates, which better separates the casting from the mold and ejects the casting from the mold cavity, achieving rapid demolding.

[0016] 3. The device of this utility model increases the heat dissipation area on the outer surface of the mold, enhances heat conduction and promotes air convection to achieve efficient heat dissipation through the setting of heat dissipation fins and fan assembly.

The worktable 1 is flush with the worktable 1. A U-shaped frame 12 is installed below the worktable 1 and is fixedly connected to the worktable 1. An installation plate 13 is installed on the inner side of the U-shaped frame 12. A second electric telescopic rod 24 is installed below the installation plate 13 and is connected to the U-shaped frame 12 by screws. The telescopic end of the second electric telescopic rod 24 is connected to the installation plate 13. Multiple connecting rods 18 are symmetrically arranged above the installation plate 13 and are fixedly connected to the installation plate 13 and the frame 17 at both ends, respectively. The connecting rods 18 are slidably connected to the lower mold 4. A sliding groove 19 is provided on the inner wall of the U-shaped frame 12. Both ends of the installation plate 13 extend into the interior of the sliding groove 19 and are slidably connected to the U-shaped frame 12. A support frame 2 is installed below each end of the worktable 1 and is fixedly connected to the worktable 1. An electrical control box 3 is installed at the front end of the worktable 1 and is connected to the worktable 1 by screws.

[0027] In use: The upper mold 5 and the lower mold 4 are closed. Flowing liquid is injected into the mold cavity 15 through the injection nozzle 8. Coolant is sent into the upper cooling cavity 21 and the lower cooling cavity 22 through the inlet valve 11. The coolant flowing in the upper cooling cavity 21 and the lower cooling cavity 22 absorbs heat. The coolant that has absorbed heat then flows out through the drain valve 23, which accelerates the cooling and shaping of the casting in the mold cavity 15. After cooling and shaping are completed, the mold is opened. The second electric telescopic rod 24 is driven to apply a pushing force to the mounting plate 13. An upward pushing force is applied from the bottom of the casting through the frame 17 and the connecting rod 18, which pushes the casting out of the mold cavity 15, achieving rapid demolding.

[0028] Please see Figure 4 and Figure 6 A vibration motor 20 is installed above the center of the mounting plate 13, and the vibration motor 20 is connected to the mounting plate 13 by screws. The vibration motor 20 drives the mounting plate 13 to vibrate, and the vibration force is transmitted to the frame 17 through the connecting rod 18, so that the frame 17 and the casting connection part resonate, which can better separate the casting from the mold and improve the integrity of the demolding.

[0029] Please see Figure 1 , Figure 2 and Figure 3 Heat dissipation fins 10 are provided on the outer surfaces of both the lower mold 4 and the upper mold 5, and the heat dissipation fins 10 are integrated with the lower mold 4 and the upper mold 5. Fan assemblies 14 are provided on both sides of the processing table 1, and the fan assemblies 14 are connected to the processing table 1 by screws. The fan assemblies 14 are located below the heat dissipation fins 10. The heat dissipation fins 10 increase the heat dissipation area, enhance heat conduction, and promote air convection on the outer surface of the mold to achieve efficient heat dissipation. The fan assembly 14 accelerates the air flow and uses the fast-flowing airflow to transfer and release the heat on the heat dissipation fins 10, further improving the heat dissipation effect of the mold.

[0030] Please see Figure 1 and Figure 3 A connecting plate 6 is provided on both sides of the upper mold 5, and the connecting plate 6 is fixedly connected to the upper mold 5. A first electric telescopic rod 7 is provided on both sides of the lower mold 4, and the first electric telescopic rod 7 is connected to the processing table 1 by screws.

A column 16 is provided above each of the four corners of the lower mold 4, and the column 16 is fixedly connected to the lower mold 4. The column 16 is correspondingly set with the through hole 9, and the column 16 is slidably connected to the upper mold 5. The first electric telescopic rod 7 drives the upper mold 5 to rise and fall. With the rise and fall of the upper mold 5, the casting mold opens and closes. The column 16, in conjunction with the through hole 9, positions the mold when it is closed, thereby improving the mold closing accuracy of the casting mold.

[0031] Working principle: The first electric telescopic rod 7 drives the upper mold 5 to descend, and the upper mold 5 and lower mold 4 close. Flowing liquid is injected into the mold cavity 15 through the injection nozzle 8. Coolant is sent into the upper cooling cavity 21 and lower cooling cavity 22 through the inlet valve 11. The coolant flowing in the upper cooling cavity 21 and lower cooling cavity 22 absorbs heat. The heat-absorbing coolant then flows out through the drain valve 23, accelerating the cooling and shaping of the casting in the mold cavity 15. The fan assembly 14 is turned on to accelerate the airflow on the surface of the heat dissipation fins 10, further improving the heat dissipation effect of the mold. After cooling and shaping, the first electric telescopic rod 7 drives the upper mold 5 to rise and open the mold. The second electric telescopic rod 24 applies a pushing force to the mounting plate 13. An upward pushing force is applied from the bottom of the casting through the frame 17 and connecting rod 18. The vibration motor 20 is turned on to drive the mounting plate 13 to vibrate. The vibration force is transmitted to the frame 17 through the connecting rod 18, causing the connection between the frame 17 and the casting to resonate, pushing the casting out of the mold cavity 15, achieving rapid demolding.
