Description

Technical Field

[0001] This invention relates to the field of valve casting technology, and more specifically, to a casting production apparatus for valve casting. Background Technology

[0002] Casting production ensures that the sealing and strength of subsequent valves meet the standards through quantitative casting, and is usually carried out in batches with cooling equipment to speed up the casting process.

[0003] Patent CN219944602U relates to a casting production device for valve casting, belonging to the field of valve casting technology. It includes a casting device body with a casting furnace mounted on its inner wall. A rotating handle is mounted on one outer surface of the casting furnace. Two sets of auxiliary lifting rods are symmetrically arranged on the lower outer surface of the casting device body. Supporting rings are mounted on the lower outer surfaces of the two sets of auxiliary lifting rods, and auxiliary bearings are mounted on the inner walls of the supporting rings, located between the casting furnace and the supporting rings. A tilting handle is mounted on one outer surface of the casting device body. Two sets of rotating shafts are symmetrically arranged on the front and rear outer surfaces of the casting device body. This patent is used for the erection and rotation of the casting furnace. The rotating shafts and sliding positioning rods are used to adjust the angle of the casting device body to facilitate casting and firing.

[0004] In the aforementioned patent, a rotating shaft and a sliding positioning rod are used to adjust the angle of the main body of the casting device to facilitate casting and firing. However, after prolonged use, the casting equipment is prone to leakage. High-temperature molten steel dripping can easily burn the operator, and the steel slag formed after the leaked liquid cools can block the equipment, causing the equipment to stop or the parts to be damaged. At the same time, if the casting mold rotates too fast, the molten steel will overflow, and the air bubbles inside the molten steel will affect the molding effect of the parts. Therefore, it is necessary to design a casting production device for valve casting to solve the above problems. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a casting production apparatus for valve casting, which solves the technical problems of dripping phenomenon in the casting equipment after long-term use in the prior art, the high temperature molten steel dripping can easily burn the operator, and the steel slag formed after the leakage cools can block the equipment, causing the equipment to stop or the parts to be damaged. At the same time, the casting mold rotates too fast, which can cause the molten steel to overflow, and the air bubbles inside the molten steel can affect the molding effect of the parts.

[0006] According to one aspect, at least one embodiment of the present invention provides a casting production apparatus for valve casting, including a casting plate and an anti-drip assembly. A casting frame is fixedly installed on the top of the casting plate, a lead screw is rotatably installed on the inner wall of the casting frame, and a casting table is slidably installed on the inner wall of the casting frame. The casting table is threadedly connected to the lead screw, and casting equipment is provided on the inner wall of the casting table. The anti-drip assembly includes a heat dissipation frame, a rotating frame, a casting mold, a hollow plate, a connecting plate, a receiving plate, an elastic telescopic rod, and a limiting groove. The heat dissipation frame is fixedly installed on the top of the casting plate, and the top of the casting plate is provided with... The motor, the rotating frame is fixedly installed at the motor output end, the casting mold is set on the top of the rotating frame, the hollow plate is fixedly installed on the left side of the casting frame, the connecting plate is slidably installed on the inner wall of the hollow plate, the receiving plate is slidably installed on the inner wall of the connecting plate, the elastic telescopic rod is fixedly installed on the right side of the casting table, and the limiting groove is opened on the top of the rotating frame. The liquid inside the hollow plate is squeezed downward by the connecting plate. The downward movement of the liquid inside the hollow plate will squeeze the receiving plate to move to the left. The leftward movement of the receiving plate will block the bottom of the casting equipment. The hollow plate contains liquid.

[0007] For example, in a casting production apparatus for valve casting provided in at least one embodiment of the present invention, a sealing ring is provided between the hollow plate and the connecting plate, which can increase the sealing between the hollow plate and the connecting plate; a sealing strip is provided between the hollow plate and the receiving plate, which can increase the sealing between the hollow plate and the receiving plate; and the free end of the elastic telescopic rod is in contact with the limiting groove.

[0008] The connecting plate is in contact with the casting equipment. A spring is provided between the connecting plate and the hollow plate to support the connecting plate. The elastic telescopic rod is used to limit the rotation frame. The receiving plate is used to block the dripping molten steel. The free end of the elastic telescopic rod moves downward under its own elastic force. The free end of the elastic telescopic rod moves downward and contacts the inner wall of the limiting groove and restores the limiting position on the rotation frame.

[0009] According to another aspect, at least one embodiment of the present invention also provides a casting production apparatus for valve casting, further comprising an anti-sway component and a defoaming component. The anti-sway component is used to prevent molten steel from overflowing due to the casting mold, and the defoaming component is used to reduce air bubbles inside the molten steel. The anti-sway component includes a vertical plate, a horizontal roller, an elastic telescopic block, a control frame, a curved panel, an arc-shaped rubber, and a connecting frame. The control frame is inserted into the gap between the connecting frames and limits the connecting frames, preventing them from rotating due to the limit imposed by the control frame. The vertical plate is fixedly installed on the top of the inner wall of the casting table, the horizontal roller is rotatably installed on the bottom of the vertical plate, the elastic telescopic block is fixedly installed on the inner wall of the casting frame, the control frame is fixedly installed on the free end of the elastic telescopic block, the curved panel is fixedly installed on the rear side of the middle of the control frame, the arc-shaped rubber is fixedly installed on the front side of the control frame, and the connecting frame is fixedly installed on the circumferential surface of the rotating frame.

[0010] The arc-shaped rubber contacts the connecting frame, and the side of the connecting frame away from the rotating frame is set as an inclined surface. The transverse roller contacts the curved panel. The arc-shaped rubber undergoes slow deformation, causing the connecting frame to rotate slowly. The slow rotation of the connecting frame causes the rotating frame and the casting mold to rotate slowly.

[0011] For example, in a casting production apparatus for valve casting provided by at least one embodiment of the present invention, the degassing component includes a degassing frame, a degassing plate, a degassing ring, and a spring telescopic block. When the degassing plate moves forward, it will impact the degassing ring and generate vibration. The vibration of the degassing plate will cause the casting mold at the top of the rotating frame to vibrate together. The degassing frame slides through the front side of the heat sink frame. The degassing plate is fixedly installed on the top of the degassing frame. The degassing ring is fixedly installed on the inner wall of the heat sink frame. A traction frame is fixedly installed at the bottom of the degassing frame. The spring telescopic block is disposed between the traction frame and the heat sink frame.

[0012] The heat dissipation frame has a wiring hole on its circumference. A cooling device is installed inside the heat dissipation frame. The wiring hole is used to send the power cord into the heat dissipation frame. The bubble removal frame moves to the rear and resets, which drives the traction frame to move to the rear. The traction frame moves back and forth to stretch the power cord of the cooling device.

[0013] The left side of the bubble-dissolving rack is set as an inclined surface. By setting the left side of the bubble-dissolving rack as an inclined surface, the friction force when the bubble-dissolving rack comes into contact with the connecting frame can be reduced. The bubble-dissolving rack abuts against the connecting frame, and the bubble-dissolving plate contacts the bottom of the rotating frame. The reciprocating movement of the bubble-dissolving rack can block the power cord.

[0014] The beneficial effects of this invention are as follows: In this invention, the downward movement of the liquid inside the hollow plate forces the receiving plate to move to the left. This leftward movement of the receiving plate shields the bottom of the casting equipment. The leftward movement of the receiving plate directly shields the bottom of the casting equipment, actively catching the dripping high-temperature molten steel. This prevents the molten steel from dripping directly onto the ground or equipment parts, thus preventing operator burns. It also prevents the formation of slag that can obstruct the equipment after the leaked liquid cools. The free end of the elastic telescopic rod moves downward to contact the inner wall of the limiting groove and restores its limiting position on the rotating frame. This automatic limiting locks the casting mold at the preset bottom of the casting equipment, preventing misalignment between the casting mold and the casting equipment caused by mold displacement, thereby adapting to the needs of mass production.

[0015] In this invention, the rotating frame and the casting mold cannot rotate during the casting operation because the connecting frame cannot rotate. The fact that the casting mold does not rotate can prevent the molten steel inside from shaking, reduce casting defects caused by liquid flow disturbance, and thus improve the mechanical properties and sealing of the casting.

[0016] In this invention, the arc-shaped rubber generates slow deformation, causing the connecting frame to rotate slowly. The slow rotation of the connecting frame causes the rotating frame and the casting mold to rotate slowly. The slow rotation of the casting mold can prevent the high-temperature molten steel from splashing out due to centrifugal force, further preventing operator burns, while reducing the risk of equipment damage and production interruption, thereby ensuring the continuous operation of casting.

[0017] In this invention, the bubble removal plate moves forward and impacts the bubble removal ring, causing vibration. The vibration of the bubble removal plate causes the casting mold at the top of the rotating frame to vibrate as well. The vibration disturbs the molten steel in the mold, causing internal bubbles to rise and be discharged quickly, further preventing porosity in the valve casting and ensuring a dense internal structure of the valve casting.

[0018] In this invention, the bubble-removing frame moves backward and resets, causing the traction frame to move backward. The reciprocating movement of the traction frame stretches the power cord of the cooling equipment. Stretching the power cord can prevent poor contact caused by cord tangling, thereby ensuring the continuous and stable operation of the cooling equipment and ensuring uniform cooling of the casting. The reciprocating movement of the bubble-removing frame can also shield the power cord, thereby preventing molten steel overflowing from the casting mold from directly adhering to the surface of the power cord and eliminating safety accidents such as fires caused by short circuits.

[0027] like Figures 1-7The diagram illustrates a casting production apparatus for valve casting according to an embodiment of the present invention. It includes a casting plate 1 and an anti-drip assembly. A casting frame 2 is fixedly mounted on the top of the casting plate 1. A lead screw 4 is rotatably mounted on the inner wall of the casting frame 2. A casting platform 5 is slidably mounted on the inner wall of the casting frame 2, and the casting platform 5 is threadedly connected to the lead screw 4. A casting device 6 is provided on the inner wall of the casting platform 5. The anti-drip assembly includes a heat dissipation frame 7, a rotating frame 8, a casting mold 9, a hollow plate 10, a connecting plate 11, a receiving plate 12, an elastic telescopic rod 13, and a limiting groove 14. The heat dissipation frame 7 is fixedly mounted on the top of the casting plate 1. A motor is provided on the top of the casting plate 1. The rotating frame 8 is fixedly mounted on the output end of the motor. The casting mold 9 is located on the top of the rotating frame 8. The hollow plate 10 is fixedly mounted on the left side of the casting frame 2. The connecting plate 11 is slidably mounted on the inner wall of the hollow plate 10. The receiving plate... The 12 is slidably installed on the inner wall of the connecting plate 11, the elastic telescopic rod 13 is fixedly installed on the right side of the casting table 5, the limiting groove 14 is opened on the top of the rotating frame 8, the hollow plate 10 is filled with liquid, the liquid inside the hollow plate 10 is high-temperature synthetic silicone oil, its high temperature resistance is far superior to ordinary hydraulic oil, and there is no obvious evaporation or boiling phenomenon at high temperature. At the same time, the low expansion characteristics can greatly reduce the volume change of the liquid after heating, avoid the receiving plate 12 being continuously pressured, actively receive the dripping high-temperature molten steel, and prevent the molten steel from dripping directly onto the ground or equipment parts, thereby preventing operator burns. The hollow plate 10 has an independent cavity on the left side, and the independent cavity contains a heat dissipation pipe. The heat dissipation pipe is connected to an external water cooling heat dissipation device, and the water cooling heat dissipation device circulates heat dissipation to the hollow plate 10 to ensure that the high-temperature synthetic silicone oil inside the hollow plate 10 is at a suitable working temperature.

[0028] A sealing ring is provided between the hollow plate 10 and the connecting plate 11 to increase the sealing performance between them. A sealing strip is provided between the hollow plate 10 and the receiving plate 12 to increase the sealing performance between them. The free end of the elastic telescopic rod 13 contacts the limiting groove 14 to prevent the formation of steel slag that may obstruct the equipment after the liquid cools. The hollow plate 10, the connecting plate 11, and the receiving plate 12 are all made of high-purity, high-alumina refractory material, and the surfaces of the hollow plate 10, the connecting plate 11, and the receiving plate 12 are all covered with zirconium-containing ceramic fiber plates to insulate against the radiant heat of the molten steel.

[0029] In this embodiment, the connecting plate 11 contacts the casting equipment 6. A spring is provided between the connecting plate 11 and the hollow plate 10 to support the connecting plate 11. The elastic telescopic rod 13 is used to limit the rotation frame 8. The receiving plate 12 is used to block the dripping molten steel. The free end of the elastic telescopic rod 13 moves downward under its own elastic force. The free end of the elastic telescopic rod 13 moves downward and contacts the inner wall of the limiting groove 14 and restores the limiting of the rotation frame 8. The automatic limiting can lock the casting mold 9 at the bottom of the preset casting equipment 6, thereby avoiding the misalignment between the casting mold 9 and the casting equipment 6 caused by the offset of the casting mold 9, and thus adapting to the rhythm requirements of mass production.

[0030] See in some examples Figures 1-7 When casting the valve fittings, the free end of the elastic telescopic rod 13 is pushed upward. The upward movement of the free end of the elastic telescopic rod 13 will disengage from the limiting groove 14 and release the limiting of the rotating frame 8. After the limiting of the rotating frame 8 is released, a DC motor is installed on the top of the casting frame 2 and the output end of the DC motor is fixedly connected to the lead screw 4. The operation of the DC motor drives the lead screw 4 to rotate. The rotation of the lead screw 4 squeezes the casting table 5 to move downward. The downward movement of the casting table 5 drives the casting equipment 6 to move downward. The downward movement of the casting equipment 6 will disengage from the connecting plate 11, so that the connecting plate 11 moves downward and resets under the elastic force of the spring. The downward movement and reset of the connecting plate 11 will draw the liquid inside the hollow plate 10. The liquid inside the hollow plate 10 is drawn in by the connecting plate 11, causing a negative pressure to be generated in the hollow plate 10. The negative pressure causes the receiving plate 12 to move to the left and reset under the action of the negative pressure. The leftward movement of the hollow plate 10 will remove the obstruction to the casting equipment 6. At the same time, the casting equipment 6 moves downward to align with the casting mold 9 and performs the casting operation. After the casting operation is completed, the DC motor drives the lead screw 4 to reverse. The reverse movement of the lead screw 4 squeezes the casting table 5 to move upward and reset. The upward movement of the casting table 5 drives the casting equipment 6 to move upward and reset. The upward movement of the casting equipment 6 will squeeze the connecting plate 11 to move upward. The upward movement of the connecting plate 11 will squeeze the spring 1.

[0031] Simultaneously, the upward movement of the connecting plate 11 compresses the liquid inside the hollow plate 10. The liquid inside the hollow plate 10, compressed by the connecting plate 11, moves downward, causing the receiving plate 12 to move to the left. This leftward movement of the receiving plate 12 obstructs the bottom of the casting equipment 6. Simultaneously, the motor drives the rotating frame 8 to rotate, causing the casting mold 9 to rotate and move the empty casting mold 9 to the bottom of the casting equipment 6. The empty casting mold 9 then repeats the casting process. After all empty casting molds 9 have been cast, the motor continues to drive the rotating frame 8 to rotate, aligning the elastic telescopic rod 13 with the limiting groove 14. Once aligned, the free end of the elastic telescopic rod 13 moves downward under its own elastic force, contacting the inner wall of the limiting groove 14 and restoring its limiting effect on the rotating frame 8. refer to Figures 1-7 In some embodiments, an anti-swaying component and a defoaming component are also included. The anti-swaying component is used to prevent molten steel from overflowing due to the casting mold 9, and the defoaming component is used to reduce air bubbles inside the molten steel. The anti-swaying component includes a vertical plate 151, a horizontal roller 152, an elastic telescopic block 153, a control frame 154, a curved panel 155, an arc-shaped rubber 156, and a connecting frame 157. The vertical plate 151 is fixedly installed on the top of the inner wall of the casting table 5, the horizontal roller 152 is rotatably installed on the bottom of the vertical plate 151, the elastic telescopic block 153 is fixedly installed on the inner wall of the casting frame 2, the control frame 154 is fixedly installed on the free end of the elastic telescopic block 153, the curved panel 155 is fixedly installed on the rear side of the middle part of the control frame 154, the arc-shaped rubber 156 is fixedly installed on the front side of the control frame 154, and the connecting frame 157 is fixedly installed on the circumferential surface of the rotating frame 8. The casting mold 9 does not rotate, which can avoid the swaying of the unsolidified molten steel inside, reduce casting defects caused by liquid flow disturbance, and thus improve the mechanical properties and sealing of the casting.

[0032] The arc-shaped rubber 156 contacts the connecting frame 157. The side of the connecting frame 157 away from the rotating frame 8 is set as an inclined surface. The transverse roller 152 contacts the curved panel 155. The arc-shaped rubber 156 undergoes slow deformation, causing the connecting frame 157 to rotate slowly. The slow rotation of the connecting frame 157 causes the rotating frame 8 and the casting mold 9 to rotate slowly. The slow rotation of the casting mold 9 can prevent the high-temperature molten steel from splashing out due to centrifugal force, reduce the risk of equipment damage and production interruption, and thus ensure the continuous operation of casting.

[0033] In this embodiment, the degassing assembly includes a degassing frame 161, a degassing plate 162, a degassing ring 163, and a spring telescopic block 165. The degassing frame 161 slides through the front side of the heat sink frame 7. The degassing plate 162 is fixedly installed on the top of the degassing frame 161. The degassing ring 163 is fixedly installed on the inner wall of the heat sink frame 7. A traction frame 164 is fixedly installed at the bottom of the degassing frame 161. The spring telescopic block 165 is disposed between the traction frame 164 and the heat sink frame 7. Vibration can cause disturbance in the molten steel in the mold, prompting the internal bubbles to rise and be discharged quickly, further preventing the valve casting from having pores, thus ensuring the dense internal structure of the valve casting.

[0034] The heat sink frame 7 has a wiring hole 166 on its circumferential surface. A cooling device is installed inside the heat sink frame 7. The wiring hole 166 is used to send the power cord into the heat sink frame 7. The bubble removal frame 161 moves backward and resets, which drives the traction frame 164 to move backward. The traction frame 164 moves back and forth to stretch the power cord of the cooling device. Stretching the power cord can prevent poor contact caused by the power cord tangling, thereby ensuring the continuous and stable operation of the cooling device and ensuring uniform cooling of the casting.

[0035] The left side of the bubble removal rack 161 is set as an inclined surface. By setting the left side of the bubble removal rack 161 as an inclined surface, the friction between the bubble removal rack 161 and the connecting rack 157 can be reduced. The bubble removal rack 161 and the connecting rack 157 abut against each other, and the bubble removal plate 162 contacts the bottom of the rotating rack 8. The reciprocating movement of the bubble removal rack 161 can shield the power cord. The reciprocating movement of the bubble removal rack 161 can shield the power cord, thereby preventing the molten steel overflowing from the casting mold 9 from directly adhering to the surface of the power cord, and preventing safety accidents such as fire caused by short circuit.

[0036] In this embodiment, the downward movement of the casting table 5 will cause the vertical plate 151 to move downward, the downward movement of the vertical plate 151 will cause the horizontal roller 152 to move downward, the downward movement of the horizontal roller 152 will contact the curved panel 155 and squeeze the curved panel 155 to move forward, the forward movement of the curved panel 155 will cause the control frame 154 to move forward, the forward movement of the control frame 154 will cause the elastic telescopic block 153 to move forward, the elastic telescopic block 153 will move forward and store force, at the same time the forward movement of the control frame 154 will squeeze and deform the arc-shaped rubber 156 and insert it into the gap between the connecting frame 157, the control frame 154 inserts into the gap between the connecting frame 157 and limits the connecting frame 157, the connecting frame 157 cannot rotate due to the limit of the control frame 154; The inability of the connecting frame 157 to rotate prevents the rotating frame 8 and the casting mold 9 from rotating during the casting operation. When the casting table 5 moves upward to reset, the upward movement of the casting table 5 will drive the vertical plate 151 and the horizontal roller 152 to move upward. The upward movement of the horizontal roller 152 will disengage from the curved panel 155. After the curved panel 155 disengages from the horizontal roller 152, the control frame 154 moves backward to reset under the elastic force of the elastic telescopic block 153. The control frame 154 moves backward to reset, causing the arc-shaped rubber 156 to recover under its own elastic force. The recovered arc-shaped rubber 156 will continue to contact the connecting frame 157, so that when the connecting frame 157 rotates, it will squeeze the arc-shaped rubber 156 to produce a slow deformation. The slow deformation of the arc-shaped rubber 156 causes the connecting frame 157 to rotate slowly. The slow rotation of the connecting frame 157 causes the rotating frame 8 and the casting mold 9 to rotate slowly.

[0037] When the connecting frame 157 rotates, it will contact the inclined surface of the bubble removal frame 161 and squeeze the bubble removal frame 161. The bubble removal frame 161 moves forward due to the squeezing of the connecting frame 157. The forward movement of the bubble removal frame 161 will drive the bubble removal plate 162 to move forward. The forward movement of the bubble removal plate 162 will hit the bubble removal ring 163 and generate vibration. The vibration of the bubble removal plate 162 will cause the casting mold 9 on the top of the rotating frame 8 to vibrate together. At the same time, the forward movement of the bubble-removing frame 161 will drive the traction frame 164 to move forward. The forward movement of the traction frame 164 will pull and store force on the free end of the spring telescopic block 165. After the connecting frame 157 continues to rotate and disengages from the bubble-removing frame 161, the bubble-removing frame 161 moves backward and resets under the elastic force of the spring telescopic block 165. The bubble removal rack 161 moves backward and resets, causing the traction rack 164 to move backward. The reciprocating movement of the traction rack 164 stretches the power cord of the cooling equipment, and the reciprocating movement of the bubble removal rack 161 can shield the power cord, thereby preventing the molten steel overflowing from the casting mold 9 from directly adhering to the surface of the power cord.
