Description

Technical Field

[0001] The present invention relates to the technical field of die steel smelting and casting, and specifically relates to a protection device for die steel smelting and casting and its use method. Background Art

[0002] Die steel smelting and casting refers to the process of pouring the melted metal liquid into a mold to cool and solidify it into a steel part with the required shape and size. Smelting and casting is the final operation in the steelmaking production process. By pouring the refined molten steel into an ingot mold, the molten steel solidifies in the mold to form the required ingot. During the casting process, factors such as the temperature, casting speed, and method of the molten steel will affect the quality of the ingot. The traditional casting process is to place the raw materials inside a melting furnace for melting. After the raw materials are melted, the operator will drive the melting furnace to move above the mold and pour the melted raw materials into the mold for casting. When the melting furnace pours the melted raw materials into the mold, the raw materials will flow down rapidly by gravity and impact the inner wall of the mold, easily causing the melted raw materials to burst out from the inside of the mold, posing a safety hazard.

[0013] Further, a usage method of a protection device for mold steel smelting and casting includes the following steps: S1: When the force-bearing rod moves, it pushes the lifting plate upward. When the lifting plate moves, it pushes the sealing plate away from the inner wall of the through hole through the sliding rod. At this time, the conical frame will contact the top of the mold, and the raw materials entering the feeding frame flow into the mold through the conical frame for casting processing; S2: When the lifting plate moves downward, it pushes the triangular plate downward through the elastic rod. When the triangular plate moves downward, it will contact the surface of the contact plate.

When the chute ring moves, it pushes the mold upward through the connection of the rotating ring and the linkage plate, so that the top of the mold contacts the bottom of the conical frame, reducing the distance between the mold and the conical frame; S4: Start the motor to drive the mold to rotate. When the mold rotates, it pushes the force-bearing bottom plate to rotate. When the force-bearing bottom plate rotates from the inside of the extrusion groove to the top of the extrusion ring, the force-bearing bottom plate will push the circular plate upward through the vertical rod, and the circular plate will push the steel casting to the outer end of the mold.

[0014] The present invention has the following beneficial effects: After the raw materials are melted in the melting furnace of the present invention, the traveling crane is started to move on the surface of the positioning frame. When the traveling crane moves, the melting furnace is pushed towards the surface of the discharging component by the electric telescopic frame. The power device is started to drive the rotating rod to rotate. When the rotating rod rotates, it pushes the melting furnace to tilt. The discharging rack will move to the top of the discharging component as the melting furnace tilts. At this time, the raw materials inside the melting furnace will enter the inside of the discharging component through the discharging rack. The electric telescopic frame can adjust the height of the melting furnace, so that the melting furnace can fit on the top of the discharging component after tilting, avoiding splashing when the raw materials flow out. A vibrating component is arranged on the surface of the discharging component. The vibration generated by the vibrating component can make the raw materials in the discharging component flow into the forming component for casting treatment. After the raw materials enter the inside of the forming component and complete casting, the forming component will move into the cooling rack for cooling treatment, avoiding the high temperature of the forming component from scalding the operator. When the forming component rotates, it will push the separating component upward. When the separating component moves upward, it will push the formed casting towards the outer end of the forming component for discharging the casting.

[0015] When the forming component moves upward in the present invention, it will contact the bottom of the stress rod and push it upward. When the stress rod moves, it pushes the lifting plate upward. When the lifting plate moves, it pushes the sealing plate away from the inner wall of the through hole through the sliding rod. At this time, the conical frame will contact the top of the mold. The raw materials entering the inside of the feeding rack flow into the inside of the mold through the conical frame for casting processing. The bottom of the conical frame will contact the top of the mold, avoiding splashing caused by the impact of the raw materials on the inner wall of the mold and improving the safety of the steel casting during casting. When the mold moves downward, the lifting plate uses the elasticity of the elastic rod to push the sealing plate downward to seal the conical frame and prevent the raw materials inside the conical frame from dripping.

[0016] When the lifting plate moves downward in the present invention, it pushes the triangular plate downward through the elastic rod. When the triangular plate moves downward, it will contact the surface of the contact plate. When the triangular plate separates from the contact plate, the triangular plate uses the elasticity of the elastic rod to impact the inner wall of the groove to generate vibration. The vibration will be transmitted to the inner wall of the conical frame through the lifting plate. The raw materials inside the conical frame will flow out quickly after being vibrated, avoiding a large amount of raw materials remaining inside the conical frame.

[0017] When the raw materials of the present invention need to be added to the inner wall of the mold, the hydraulic rod is started to push the chute ring upward. When the chute ring moves, it drives the mold to move upward through the connection between the rotating ring and the linkage plate, so that the top of the mold contacts the bottom of the conical frame, reducing the distance between the mold and the conical frame, and avoiding the splashing of the raw materials due to excessive impact force caused by the long distance between the mold and the conical frame. After the inside of one mold is filled with raw materials, the hydraulic rod is used to move downward, and the motor is started to drive the cross-hole rod to rotate. When the cross-hole rod rotates, it drives the mold to rotate through the connection between the cross rod and the center plate, so that the four molds can be rotated to the lower part of the conical frame in turn to inject raw materials, improving the casting efficiency of the steel casting.

[0018] After the raw materials of the present invention are poured into the inside of the mold, the hydraulic rod is started to push the mold into the inside of the cooling rack, so that the raw materials can be quickly cooled down inside the mold. After the mold is cooled down, the motor is started to drive the mold to rotate. When the mold rotates, it drives the force-bearing bottom plate to rotate. When the force-bearing bottom plate rotates from the inside of the extrusion groove to the top of the extrusion ring, the force-bearing bottom plate will push the round plate upward through the vertical rod, and the round plate will push the steel casting to the outer end of the mold, so as to facilitate the operator to take the steel casting.

[0019] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

In the present invention, when the forming component 19 moves upward, it will contact the bottom of the stress rod 37 and push it upward. When the stress rod 37 moves, it pushes the lifting plate 38 upward.

When the mold 57 moves downward, the lifting plate 38 uses the elasticity of the elastic rod 32 to push the sealing plate 36 downward, and the sealing plate 36 is used to seal the conical frame 31 to prevent the raw material inside the conical frame 31 from dripping. The sealing plate 36 is located inside the conical frame 31, and the lower surface of the sealing plate 36 contacts the inner wall of the through hole 35.

When the chute ring 51 moves, it pushes the mold 57 upward through the connection of the rotating ring 53 and the linkage plate 54, so that the top of the mold 57 contacts the bottom of the conical frame 31, reducing the distance between the mold 57 and the conical frame 31, and avoiding the situation that the impact force of the raw materials is too large and splashes occur due to the long distance between the mold 57 and the conical frame 31. The top of the cross-hole rod 55 is fixedly connected to a stabilizing plate 50. The top of the stabilizing plate 50 is fixedly connected to the output end of the motor 6. The number of support rings 58 is set to four. After the inside of one mold 57 is filled with raw materials, the hydraulic rod 52 is used to move downward, and the motor 6 is started to drive the cross-hole rod 55 to rotate. When the cross-hole rod 55 rotates, it drives the mold 57 to rotate through the connection of the cross rod 59 and the central plate 56, so that the four molds 57 can be rotated to the lower part of the conical frame 31 in turn to inject raw materials, improving the casting efficiency of the steel casting.

After the raw material is poured into the mold 57 in the present invention, the hydraulic rod 52 is started to push the mold 57 to move into the cooling rack 1, so that the raw material can be quickly cooled and cooled inside the mold 57. After the mold 57 is cooled, the motor 6 is started to drive the mold 57 to rotate. When the mold 57 rotates, it pushes the force-bearing bottom plate 64 to rotate. When the force-bearing bottom plate 64 rotates from the inside of the extrusion groove 63 to the top of the extrusion ring 62, the force-bearing bottom plate 64 will push the circular plate 66 to move upward through the vertical rod 65. The circular plate 66 will push the steel casting to move towards the outer end of the mold 57, so that the operator can perform the operation of taking the steel casting. The bottom of the vertical rod 65 penetrates the mold 57 and extends to the outer end of the bottom of the mold 57. The bottom of the force-bearing bottom plate 64 corresponds to the top of the extrusion ring 62.

[0033] A method for using a protection device for mold steel smelting and casting includes the following steps: S1: When the force-bearing rod 37 moves, it pushes the lifting plate 38 to move upward. When the lifting plate 38 moves, it pushes the sealing plate 36 to separate from the inner wall of the through hole 35 through the sliding rod 33. At this time, the conical frame 31 will contact the top of the mold 57. The raw material entering the feeding frame 30 flows into the mold 57 through the conical frame 31 for casting processing. S2: When the lifting plate 38 moves downward, it pushes the triangular plate 44 to move downward through the elastic rod 49. When the triangular plate 44 moves downward, it will contact the surface of the contact plate 46. When the triangular plate 44 separates from the contact plate 46, the triangular plate 44 uses the elasticity of the elastic rod 49 to impact the inner wall of the groove 45 to generate vibration, and the vibration will be transmitted to the inner wall of the conical frame 31 through the lifting plate 38. S3: When it is necessary to add raw material to the inner wall of the mold 57, the hydraulic rod 52 is started to push the sliding groove ring 51 to move upward. When the sliding groove ring 51 moves, it pushes the mold 57 to move upward through the connection of the rotating ring 53 and the linkage plate 54, so that the top of the mold 57 contacts the bottom of the conical frame 31, reducing the distance between the mold 57 and the conical frame 31. S4: The motor 6 is started to drive the mold 57 to rotate. When the mold 57 rotates, it pushes the force-bearing bottom plate 64 to rotate. When the force-bearing bottom plate 64 rotates from the inside of the extrusion groove 63 to the top of the extrusion ring 62, the force-bearing bottom plate 64 will push the circular plate 66 to move upward through the vertical rod 65. The circular plate 66 will push the steel casting to move towards the outer end of the mold 57.

[0034] During use, when the molding part 19 moves upward, it will contact the bottom of the force-bearing rod 37 and push it upward. When the force-bearing rod 37 moves, it pushes the lifting plate 38 upward. When the lifting plate 38 moves, it pushes the sealing plate 36 away from the inner wall of the through hole 35 through the sliding rod 33. At this time, the conical frame 31 will contact the top of the mold 57, and the raw material entering the inside of the feeding frame 30 flows into the inside of the mold 57 through the conical frame 31 for casting processing. The bottom of the conical frame 31 will contact the top of the mold 57 to prevent the raw material from splashing due to impact on the inner wall of the mold 57, improving the safety of the steel casting during pouring. When the mold 57 moves downward, the lifting plate 38 uses the elasticity of the elastic rod 32 to push the sealing plate 36 downward to seal the conical frame 31 and prevent the raw material inside the conical frame 31 from dripping. When the lifting plate 38 moves downward, it pushes the triangular plate 44 downward through the elastic rod 49. When the triangular plate 44 moves downward, it will contact the surface of the contact plate 46. When the triangular plate 44 separates from the contact plate 46, the triangular plate 44 uses the elasticity of the elastic rod 49 to impact the inner wall of the groove 45 to generate vibration. The vibration will be transmitted to the inner wall of the conical frame 31 through the lifting plate 38. The raw material inside the conical frame 31 will flow out quickly after being vibrated, preventing a large amount of raw material from remaining inside the conical frame 31. When the raw material needs to be added to the inner wall of the mold 57, the hydraulic rod 52 is started to push the sliding groove ring 51 upward. When the sliding groove ring 51 moves, it pushes the mold 57 upward through the connection between the rotating ring 53 and the linkage plate 54, making the top of the mold 57 contact the bottom of the conical frame 31 and reducing the distance between the mold 57 and the conical frame 31 to prevent the raw material from splashing due to excessive impact force caused by a large distance between the mold 57 and the conical frame 31. After the inside of one mold 57 is filled with raw material, the hydraulic rod 52 is used to move downward, and the motor 6 is started to drive the cross-hole rod 55 to rotate. When the cross-hole rod 55 rotates, it drives the mold 57 to rotate through the connection between the cross rod 59 and the center plate 56, so that the four molds 57 can be rotated to the lower part of the conical frame 31 in turn to inject raw material, improving the casting efficiency of the steel casting. After the raw material is poured into the inside of the mold 57, the hydraulic rod 52 is started to push the mold 57 into the inside of the cooling frame 1 to allow the raw material to quickly cool down inside the mold 57. After the mold 57 is cooled down, the motor 6 is started to drive the mold 57 to rotate. When the mold 57 rotates, it pushes the force-bearing bottom plate 64 to rotate. When the force-bearing bottom plate 64 rotates from the inside of the extrusion groove 63 to the top of the extrusion ring 62, the force-bearing bottom plate 64 will push the round plate 66 upward through the vertical rod 65. The round plate 66 will push the steel casting to move towards the outer end of the mold 57, so that the operator can perform the operation of taking the steel casting.
