Description

Technical Field

[0001] This utility model belongs to the field of precision casting molds, specifically a precision casting mold for alloy castings. Background Technology

[0002] Precision casting molds, also known as precision casting molds, are molds used in precision casting processes to manufacture castings.

[0003] In the existing technology, after the alloy casting is completed, it is necessary to wait for the casting to cool naturally before it can be demolded and removed. However, natural cooling is very time-consuming, and the casting is tightly adhered to the mold groove, making it difficult to remove. This reduces demolding efficiency and increases the manpower burden. It is impossible to cool and shape the casting quickly and demold it quickly. In addition, the residual heat of the mold and the casting also poses a risk of burns to the workers who are demolding. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a precision casting mold for alloy castings.

[0005] The technical solution of this utility model is as follows: an alloy casting precision casting mold includes a water tank, a lower mold fixedly connected to the top of the water tank, an upper mold provided on the top of the lower mold, a cooling groove opened in the lower part of the lower mold, cooling circulation pipes fixedly connected between the top two sides of the water tank and the lower mold, one end of each cooling circulation pipe extending into the interior of the lower mold and communicating with the two ends of the cooling groove respectively, a spray frame slidably connected to one side of the top of the water tank, hammering columns provided on both sides of the exterior of the lower mold, and a transmission assembly provided on the top of the water tank.

[0006] In a preferred embodiment, the transmission assembly includes a fixed plate and a linkage unit. The fixed plates are symmetrically fixedly connected to one side of the top of the water tank. A reciprocating screw is rotatably connected between the two fixed plates. A motor is fixedly connected to the outside of the fixed plates. The output end of the motor extends to the inside of the fixed plates and is fixedly connected to the reciprocating screw. The spray frame is threaded to the outside of the reciprocating screw. The hammer column can reciprocate through the linkage unit.

[0007] In a preferred embodiment, the linkage unit includes a turntable, which is fixedly connected to both sides of the reciprocating lead screw. A lever is fixedly connected to the outside of each of the two turntables. Limiting frames are fixedly connected to the top of the water tank and to both sides of the lower mold. Sliding plates that cooperate with the levers are slidably connected to the inner sides of the two limiting frames. Two hammering columns are fixedly connected to the tops of the two sliding plates and slidably connected to the tops of the limiting frames. A spring is provided on the outside of each hammering column between the sliding plate and the limiting frame.

[0008] In a preferred embodiment, a hose is provided between the interior of the water tank and the interior of the spray frame, and a booster pump is installed at one end of the hose inside the water tank.

[0009] In one preferred embodiment, one end of the cooling circulation pipe extends into the interior of the water tank and is equipped with a water pump. A filling port is fixedly connected to one side of the top of the water tank, and spray nozzles are fixedly connected at equal intervals to the outer side of the spray frame.

[0010] In a preferred embodiment, a support frame is fixedly connected to the outer side of the water tank away from the filling port, a cylinder is fixedly connected to the inner side of the support frame, the upper mold is fixedly connected to the output end of the cylinder, a casting port is opened on the inner side of the upper mold, and a mold groove is opened on the top of the lower mold.

[0011] The beneficial effects of this utility model are as follows:

[0012] This device achieves cooling water circulation through the cooperation of cooling tanks and cooling circulation pipes during the casting process. This not only keeps the cooling water in the cooling tank at a low temperature, improving the cooling efficiency of the lower mold, but also avoids the single-use of cooling water, thus effectively saving water resources and reducing operating costs. After casting is completed, cooling water can be sprayed onto the surface of the lower mold through a spray rack to cool the lower mold and alloy casting a second time. This prevents residual heat on the surface of the lower mold and alloy casting from causing burns to workers during demolding, facilitating demolding. Furthermore, the turntable and the lever can simultaneously drive the hammer column to strike the lower mold at high frequency, causing it to vibrate. This vibration loosens the casting inside the mold groove, facilitating subsequent rapid demolding and making it easy for workers to remove the completed casting, improving demolding efficiency and reducing manpower burden.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-6 A precision casting mold for alloy casting includes a water tank 1, a lower mold 2 fixedly connected to the top of the water tank 1, an upper mold 4 on the top of the lower mold 2, a cooling groove 5 opened in the lower part of the interior of the lower mold 2, cooling circulation pipes 17 fixedly connected between the top two sides of the water tank 1 and the lower mold 2, one end of the two cooling circulation pipes 17 extending into the interior of the lower mold 2 and respectively connected to the two ends of the cooling groove 5, a spray frame 6 slidably connected to one side of the top of the water tank 1, hammering columns 7 on both sides of the exterior of the lower mold 2, and a transmission assembly on the top of the water tank 1.

[0023] Specifically, the transmission assembly includes a fixed plate 8 and a linkage unit. The fixed plates 8 are symmetrically fixedly connected to one side of the top of the water tank 1. A reciprocating screw 9 is rotatably connected between the two fixed plates 8. A motor 10 is fixedly connected to the outside of the fixed plates 8. The output end of the motor 10 extends to the inside of the fixed plates 8 and is fixedly connected to the reciprocating screw 9. The spray frame 6 is threaded to the outside of the reciprocating screw 9. The hammer column 7 can reciprocate through the linkage unit. The linkage unit includes a turntable 11, which is fixedly connected to the reciprocating screw 9. On both sides of the lead screw 9, two turntables 11 are fixedly connected to the outside of the two turntables 11. Limiting frames 13 are fixedly connected to the top of the water tank 1 and on both sides of the lower mold 2. The inner sides of the two limiting frames 13 are slidably connected to sliding plates 14 that cooperate with the levers 12. Two hammering columns 7 are fixedly connected to the top of the two sliding plates 14 respectively. The two hammering columns 7 are slidably connected to the top of the limiting frames 13 respectively. A spring 15 is provided on the outside of the hammering column 7 and between the sliding plate 14 and the limiting frame 13.

[0024] Through the above technical solution, the upper mold 4 is lowered by starting the cylinder 20 until it fits against the lower mold 2. Then, slurry is injected through the casting port 21 on one side of the upper mold 4 to perform precision casting of the alloy casting. Next, the booster pump is started, which draws cooling water from inside the water tank 1 into the cooling tank 5 through the cooling circulation pipe 17, thereby achieving rapid cooling of the lower mold 2 and accelerating the casting process. The water is then discharged into the water tank 1 through the cooling circulation pipe 17 on the other side, thus achieving cooling water circulation. This not only keeps the cooling water in the cooling tank 5 at a low temperature, improving the cooling efficiency of the lower mold 2, but also avoids the single-use of cooling water, effectively saving water resources and reducing costs. To reduce operating costs, after the alloy casting is formed, the upper mold 4 is raised and reset by cylinder 20. Then, motor 10 and water pump are started. The output of motor 10 drives reciprocating screw 9 to rotate, causing the reciprocating screw 9 to drive the spray frame 6 to reciprocate through the threaded connection. At the same time, the water pump draws cooling water from the water tank 1 into the spray frame 6 through hose 16, and then sprays it onto the surface of the lower mold 2 through the nozzles. The reciprocating spray frame 6 can increase the spray range of the cooling water, further improving the cooling efficiency and providing secondary cooling for the lower mold 2 and the alloy casting. This prevents residual heat on the surface of the lower mold 2 and the alloy casting from causing burns to workers during demolding, facilitating demolding of the casting. The reciprocating screw... During rotation, lever 9 drives the turntables 11 on both sides to rotate synchronously. The turntables 11 then drive the external lever 12 to repeatedly push the sliding plate 14 downwards. This causes the sliding plate 14 to repeatedly drive the hammering column 7 downwards, stretching the spring 15. The rebound of the spring 15 then drives the hammering column 7 to strike the lower mold 2. This repetitive motion achieves high-frequency striking of the lower mold 2, causing vibration. This vibration loosens the casting inside the mold groove 3, facilitating rapid demolding and improving demolding efficiency. During the casting process, the device utilizes the cooling tank 5 and the cooling circulation pipe 17 to circulate cooling water. This ensures that the cooling water in the cooling tank 5 remains at a low temperature, improving the cooling effect on the lower mold. The cooling efficiency of the device 2 is high, and it avoids the one-time use of cooling water, thus effectively saving water resources and reducing operating costs. After casting is completed, the cooling water can be sprayed onto the surface of the lower mold 2 through the spray rack 6 to cool the lower mold 2 and the alloy casting a second time. This prevents the residual heat on the surface of the lower mold 2 and the alloy casting from causing burns to the workers during demolding, making it easier for workers to demold the casting. At the same time, the turntable 11 and the lever 12 can drive the hammer column 7 to strike the lower mold 2 at high frequency, causing it to vibrate. This vibration can loosen the casting inside the mold groove 3, which is conducive to subsequent rapid demolding. It is easy for workers to take out the completed casting, improving demolding efficiency and reducing manpower burden.

[0025] Specifically, a flexible hose 16 is installed between the interior of the water tank 1 and the interior of the spray frame 6. A booster pump is installed at one end of the flexible hose 16 inside the water tank 1. One end of a cooling circulation pipe 17 extends into the interior of the water tank 1 and is equipped with a water pump. A filling port 18 is fixedly connected to one side of the top of the water tank 1. Spray nozzles are fixedly connected at equal intervals to the outside of the spray frame 6. A support frame 19 is fixedly connected to the outside of the water tank 1 away from the filling port 18. A cylinder 20 is fixedly connected to one side of the inside of the support frame 19. The upper mold 4 is fixedly connected to the output end of the cylinder 20. A casting port 21 is opened on one side of the inside of the upper mold 4. A mold groove 3 is opened on the top of the lower mold 2.

[0026] Through the above technical solution, the water tank 1 can be filled with cooling water when the water supply port 18 is insufficient, and the grout can be cast into the required shape through the mold groove 3.

[0027] In operation, the upper mold 4 is lowered by starting cylinder 20 until it fits against the lower mold 2. Then, grout is injected through the casting port 21 on one side of the upper mold 4 to perform precision casting of the alloy casting. Next, the booster pump is started, drawing cooling water from inside water tank 1 into the cooling tank 5 through cooling circulation pipe 17. This rapidly cools the lower mold 2, accelerating the casting process. The water is then discharged back into water tank 1 through the other cooling circulation pipe 17, thus circulating the cooling water. This ensures the cooling water in the cooling tank 5 remains at a low temperature, improving the cooling efficiency of the lower mold 2, and avoids the single-use of cooling water, effectively saving water resources and reducing usage costs. To reduce costs, after the alloy casting is formed, the upper mold 4 is raised and reset by the cylinder 20. Then, the motor 10 and water pump are started. The output end of the motor 10 drives the reciprocating screw 9 to rotate, so that the reciprocating screw 9 drives the spray frame 6 to reciprocate through the threaded connection. At the same time, the water pump can draw the cooling water inside the water tank 1 into the interior of the spray frame 6 through the hose 16, and then spray it onto the surface of the lower mold 2 through the nozzle. The reciprocating motion of the spray frame 6 can increase the spray range of the cooling water, further improving the cooling efficiency and providing secondary cooling for the lower mold 2 and the alloy casting. This avoids the residual heat on the surface of the lower mold 2 and the alloy casting from causing burns to the workers during demolding, and facilitates the demolding of the casting. The reciprocating screw 9... During rotation, the turntables 11 on both sides rotate synchronously, causing the turntables 11 to drive the external levers 12 to repeatedly push the sliding plate 14 downwards. This causes the sliding plate 14 to repeatedly drive the hammering column 7 downwards, stretching the spring 15. The rebound of the spring 15 then drives the hammering column 7 to strike the lower mold 2. This repetitive motion achieves high-frequency striking of the lower mold 2, causing it to vibrate. This vibration loosens the casting inside the mold groove 3, facilitating rapid demolding and improving demolding efficiency. During the casting process, the device utilizes the cooling tank 5 and the cooling circulation pipe 17 to circulate the cooling water, ensuring the cooling water in the cooling tank 5 remains at a low temperature, thus improving the cooling effect on the lower mold. The improved cooling efficiency of the 2-type mold avoids the single-use of cooling water, effectively saving water resources and reducing operating costs. After casting, the cooling water can be sprayed onto the surface of the lower mold 2 via the spray rack 6 for secondary cooling of the lower mold 2 and the alloy casting. This prevents residual heat on the surface of the lower mold 2 and the alloy casting from causing burns to workers during demolding, facilitating demolding. Furthermore, the turntable 11 and the lever 12 simultaneously drive the hammer column 7 to strike the lower mold 2 at high frequency, causing vibration. This vibration loosens the casting inside the mold groove 3, facilitating subsequent rapid demolding and allowing workers to easily remove the completed casting. This improves demolding efficiency and reduces manpower burden.The water tank 1 can be replenished with cooling water through the filling port 18 when the water level is low, and the slurry can be cast into the required shape through the mold groove 3.
