Description

Technical Field

[0001] The invention relates to the technical field of protective brackets, in particular to a protective bracket for casting equipment. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that matches the shape of the part, and obtaining the required part blank after it cools and solidifies. At the same time, protective brackets installed on the outside of the casting equipment, most of which are combined with a frame, a protective fence and a protective plate to effectively protect the casting equipment.

[0003] The patent with patent announcement number CN219632555U discloses a protective bracket for casting equipment, including two fixed frames distributed front and back, and slide grooves are opened on the right sides of the two fixed frames. A top plate is fixedly installed between the upper end surfaces of the two fixed frames, and a protective frame is arranged on the right side of the two fixed frames. Observation windows are installed through the front and rear end surfaces of the protective frame. When using this patent, first push the two ends of the protective frame to move to the inside of the two slide grooves, so that the two fixed frames and the protective frame are assembled on the outside of the casting equipment body. During the operation of the casting equipment body, the staff can observe the working status of the die-casting machine body at any time through the observation window, and the door panel and the protective frame can play a protective role, so as to prevent the molten metal from splashing around and injuring others when the casting equipment body is working. When the device is disassembled, the protective frame can be directly pulled out of the fixed frame for disassembly, so as to achieve the effect of quick installation and disassembly.

[0004] However, the device still has some shortcomings: the device can shield the splashing molten metal to prevent injuries to workers, but in the process of the protective frame shielding the molten metal for a long time, the protective frame with the observation window is relatively weak. Therefore, the molten metal in the cooling process continuously releases high temperature to corrode the inner wall of the protective frame at the observation window position and then solidifies on the inner wall of the protective frame. Compared with other parts, the high temperature of the molten metal is more likely to cause corrosion and wear to the observation window position, and affects the structural integrity and maintenance difficulty of the protective frame.

Then the sealing door is lowered for processing; the motor is started, and the output end of the motor drives the reciprocating screw to rotate. The reciprocating screw limits the transmission ring through the reciprocating spiral groove. At the same time, the built-in block of the transmission ring continuously contacts the inner wall of the reciprocating spiral groove, causing the transmission ring to slide up and down along the outer wall of the reciprocating screw.

[0021] The arc surface of the arc block 10 is located on the left side movement trajectory of the U-shaped guard plate 3, the outer wall of the friction wheel 13 is in contact with the inner wall of the U-shaped guard plate 3, and an anti-drip device 4 is arranged above the U-shaped slide frame 9 to prevent water droplets formed by mist in the sealed environment when the casting equipment is running from dripping into the inside of the casting equipment.

[0022] When in use, when the casting equipment under the top plate 1 and inside the hollow support plate 2 starts to run, the staff pushes the U-shaped guard plate 3 to move into the hollow support plate 2 through external equipment, and the U-shaped guard plate 3 converts sliding friction into rolling friction through the moving component 31, and at the same time forms a sealed environment for the casting equipment through the sealing door 22. When it is necessary to add material to the inside of the casting equipment, the cable is passed through the lifting groove through the lifting equipment, and the sealing door 22 is pulled upward along the inner wall of the U-shaped limit frame 21 to add material, and then the sealing door 22 is lowered for processing; start the motor 6, and the motor 6 The output end drives the reciprocating screw rod 7 to rotate, and the reciprocating screw rod 7 limits the transmission ring 8 through the reciprocating spiral groove. At the same time, the built-in block of the transmission ring 8 continuously contacts the inner wall of the reciprocating spiral groove to enable the transmission ring 8 to slide up and down along the outer wall of the reciprocating screw rod 7. The transmission ring 8 drives the U-shaped slide frame 9 to move synchronously, and the U-shaped slide frame 9 scrapes the inner wall of the U-shaped guard plate 3, that is, the observation window position of the U-shaped guard plate 3, up and down.

The top of the L-shaped plate 41 is slidably installed on the bottom of the top plate 1, the top of the semicircular block 42 is fixedly installed on the bottom of the L-shaped plate 41, the power-assisting wheel 43 is rotatably installed on the outer wall of the L-shaped plate 41 near the center of the top plate 1, and the water-absorbing component 44 is composed of a bottom hollow shell and a top water-absorbing cotton. The hollow shell of the water-absorbing component 44 is fixedly installed on the outer wall of the L-shaped plate 41 near the center of the flat plate 1. The above coordination expands the range of movement of the water-absorbing cotton and reduces the friction resistance of the L-shaped plate 41 through the rotation of the power-assisting wheel 43, preventing the water-absorbing cotton from sliding in a pulling posture to increase its own wear, and avoiding the formation of water droplets on the top plate 1 and dripping into the metal liquid to cause a violent reaction.

[0024] The bottom arc surface of the semicircular block 42 is located on the top movement track of the U-shaped slide frame 9, the outer wall of the power-assisting wheel 43 is in contact with the bottom of the top plate 1, the top absorbent cotton of the water-absorbing component 44 is in contact with the bottom of the top plate 1, and an anti-corrosion device 5 for absorbing harmful substances generated during the operation of the casting equipment is arranged within the inner range of the water-absorbing component 44.

[0025] The anti-drip device 4 also includes a transmission rod 45, a plurality of rotating plates 46, a swinging plate 47 and a reset plate 48. The transmission rod 45 is fixedly installed on the outer wall of the power-assisting wheel 43 at one end near the outer wall of the L-shaped plate 41. A transmission groove is opened on the outer wall of the transmission rod 45. A plurality of rotating plates 46 are equidistantly and fixedly installed on the outer wall surface of the transmission rod 45. The top of the swinging plate 47 is hinged to the bottom of the hollow plate of the water absorption component 44 through a torsion spring. The swinging plate 47 is located on the movement trajectory of the rotating plate 46. The reset plate 48 is fixedly installed on the outer wall of the top of the L-shaped plate 41 near the axis of the top plate 1.

When the rotating plate 46 rotates, it continuously resists the outer wall of the swing plate 47 to cause the swing plate 47 to rotate. The hinge shaft of the swing plate 47 starts to rotate to cause the swing plate 47 to swing downward in an arc shape. Then the swing plate 47 automatically resets through the torsion spring, and this process repeats. At the same time, the L-shaped plate 41 synchronously moves toward the center direction of the top plate 1 and resists the reset plate 48 to deform. When the U-shaped slide frame 9 moves downward, the L-shaped plate 41 is reset by the elastic force of the reset plate 48. Through the above cooperation, the swing plate 47 is prompted to reduce the erosion of the bottom of the absorbent cotton by impurities in the mist, and the rotation of the rotating plate 46 disturbs the water vapor around the absorbent cotton, accelerates the mixing and evaporation of the water vapor and the heat in the processing range, and reduces the number of condensed water droplets, thereby further preventing the continuous dripping of water droplets into the metal liquid to cause more violent sputtering and the generation of bubbles in the metal liquid, thereby reducing the purity.

The outer wall of the collar 53 penetrates and is slidably installed on the outer wall of the spiral groove of the rotating rod 52. The top of the activated carbon plate 54 is equidistantly and fixedly installed below the outer wall of the collar 53.

Through the above coordination, the reciprocating swing of the elastic plate 56 is used to irregularly hit the splashing metal liquid, so as to avoid the activated carbon plate 54 from being burned and attached by the hot metal liquid, prevent the activated carbon plate 54 from reducing the absorption efficiency of harmful gases after being damaged, and speed up the replacement speed of the activated carbon plate 54, thereby increasing economic expenditure.

[0030] When in use, when the transmission rod 45 rotates, it drives the transmission belt 51 to transmit through the transmission groove on its outer wall. The transmission belt 51 drives the rotating rod 52 to start rotating along the outer wall of the L-shaped plate 41. The rotating rod 52 limits the ring 53 through the non-self-locking spiral groove on its own outer wall, and the inner wall of the spiral groove is arranged inside the ring 53 to contact the block. Therefore, when the rotating rod 52 rotates, the ring 53 can slide along the outer wall of the rotating rod 52, and the ring 53 drives the activated carbon plate 54 to move synchronously. Through the above cooperation, the activated carbon plate 54 is expanded to absorb the harmful gases generated after the metal liquid is heated, so as to prevent the harmful gases generated by the metal liquid from gradually becoming thick and forming a smoke screen that blurs the sight of the staff, making it difficult for the staff to understand the processing progress in time, and at the same time prevent the thick harmful gases after processing contact from being discharged synchronously and inhaled by the staff, thereby endangering their health. The L-shaped plate 41 stabilizes the T-shaped plate 55, and the T-shaped plate 55 limits the elastic plate 56. When the activated carbon plate 54 moves away from the L-shaped plate 41, it drives the circular frame 58 to move synchronously. The circular frame 58 will resist the inclined surface of the trapezoidal block 57 on the top of the T-shaped plate 55, causing it to generate a downward force. The trapezoidal block 57 will bend and deform downward under the influence of its own gravity and the resistance of the circular frame 58. After the elastic plate 56 is bent and deformed, it will swing back and forth in the process of its own elastic reset, and so on. Through the above cooperation, the reciprocating swing of the elastic plate 56 is used to irregularly hit the splashing metal liquid, so as to avoid the activated carbon plate 54 from being burned and attached by the hot metal liquid, prevent the activated carbon plate 54 from being damaged and reduce the absorption efficiency of harmful gases, and speed up the replacement speed of the activated carbon plate 54, thereby increasing economic expenditure.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
