[0002] A search revealed that application number 201921976811.X discloses a casting structure for motor castings, including a casting processing box. A supporting plate is fixedly installed on one outer surface of the casting processing box, a casting collection box is fixedly installed on the upper surface of the casting processing box, a guide pipe is fixedly installed on the inner surface of the casting collection box, a sand layer is provided on the inner surface of the casting processing box, a forming cavity is opened on the inner surface of the sand layer, and a fixed connecting rod and a support rod are fixedly installed on one outer surface of the supporting plate.

[0003] The electric motor casting pouring structure in this patent application uses a lifting motor in conjunction with a motor rotating shaft and a chain fixing cylinder to wind up the lifting chain, thereby pulling the pouring cylinder to tilt and pour liquid metal. However, during this process, when the liquid metal is poured, its flow forms a parabolic trajectory, which can easily spill the liquid metal outside the pouring collection box, posing a safety hazard and reducing the practicality of the device. Therefore, we propose a protective device to facilitate the pouring of metal castings. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a protective device that facilitates the pouring of metal castings.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a protective device for facilitating the pouring of metal castings, comprising a pouring processing box, a support plate fixedly installed on one side of the pouring processing box, and a pouring cylinder rotatably installed on the upper part of the support plate. The pouring processing box contains a sand layer to form a molding cavity. A pouring collection box communicating with the molding cavity is fixedly installed at the upper end of the pouring processing box. Two support frames are fixedly installed on the top right side of the support plate. The pouring cylinder is rotatably installed on the right end of the two support frames. A protective mechanism is provided on the pouring processing box, the protective mechanism including a through-hole... The irrigation cylinder has a fixed guide tube fixedly connected to the top right side of the irrigation processing box via a support frame, a telescopic guide tube that can be adjusted in height and is slidably connected inside the fixed guide tube, and a guide funnel fixedly connected to the top of the telescopic guide tube. The top right end of the irrigation cylinder is provided with a guide nozzle corresponding to the position of the guide funnel. The bottom end of the fixed guide tube extends into the irrigation collection box. The two support frames are provided with an adjustment mechanism that drives the irrigation cylinder to tilt. The adjustment mechanism includes a drive gear rotatably installed on the left end of the two support frames. A driven gear that meshes with the drive gear is fixedly installed on the left end of the outer wall of the irrigation cylinder.

[0006] Furthermore, the right ends of the two support frames are rotatably mounted with two mounting rods that are fixedly connected to the upper right side of the outer wall of the pouring cylinder.

[0007] Furthermore, the top end of the telescopic guide tube is connected to the bottom end of the guide funnel.

[0008] Furthermore, a return spring is sleeved on the upper part of the outer wall of the telescopic guide tube, and the upper and lower ends of the return spring are fixedly connected to the bottom wall of the guide funnel and the top outer wall of the fixed guide tube, respectively.

[0009] Furthermore, the passive gear and the mounting rod are on the same axis.

[0010] Furthermore, an adjusting rotating rod is fixedly installed at the middle position of the drive gear and rotatably mounted to the left end of the two support frames.

[0011] Furthermore, an installation plate is fixedly installed at the top rear end of the supporting plate, and an adjustment motor is fixedly installed on the front wall of the installation plate.

[0012] Furthermore, the output end of the regulating motor is fixedly installed at the rear end of the regulating rotating rod.

[0013] This invention provides a protective device for facilitating the pouring of metal castings. It offers the following advantages:

[0014] 1. This protective device for facilitating the pouring of metal castings, through the setting of an adjustment mechanism and a drive mechanism, controls the output of the adjustment motor to drive the drive gear to rotate via the adjustment rotating rod. This forces the driven gear meshing with the drive gear to drive the pouring cylinder to rotate clockwise around the mounting rod as the axis. This causes the liquid metal inside the pouring cylinder to pour out through the guide nozzle for the pouring operation. Under its own gravity, the liquid metal passes through the inside of the guide funnel, the inside of the telescopic guide tube, and the inside of the fixed guide tube in sequence before falling into the pouring collection box and being guided into the molding cavity. During this process, the pouring cylinder drives the guide nozzle to rotate downward, squeezing the top of the guide funnel. This forces the guide funnel to compress the return spring, causing the telescopic guide tube to move downward and retract into the fixed guide tube. This ensures that the position of the guide funnel and the position of the guide nozzle always correspond, achieving the limiting and guiding function of the device for the liquid metal, thus preventing the liquid metal from spilling outside the pouring collection box and causing safety issues, and improving the practicality of the device.

[0015] 2. This protective device for facilitating the pouring of metal castings, by means of a chain traction method, which is difficult to provide stable support and limiting for the pouring cylinder due to the movable structure of the chain itself, this device drives the pouring cylinder to rotate, tilt and move through the meshing of active and passive gears, thus providing effective support and limiting for the placement of the pouring cylinder and improving the overall stability of the device.

Detailed Implementation

[0023] A protective device for facilitating the pouring of metal castings, such as Figure 1-4As shown, the system includes a casting processing box 10, a support plate 12 fixedly installed on one side of the casting processing box 10, and a casting cylinder 11 rotatably installed on the upper end of the support plate 12. The casting processing box 10 has a molding cavity 13 formed by a sand layer inside. A casting collection box 14 connected to the molding cavity 13 is fixedly installed on the upper end of the casting processing box 10. Two support frames 16 are fixedly installed on the right side of the top of the support plate 12. The casting cylinder 11 is rotatably installed on the right end of the two support frames 16. Two mounting rods 17 are rotatably mounted and fixedly connected to the upper right side of the outer wall of the pouring cylinder 11. A protective mechanism is provided on the pouring processing box 10. The protective mechanism includes a fixed guide tube 18 fixedly connected to the right side of the top of the pouring processing box 10 via a bracket, a height-adjustable telescopic guide tube 19 slidably connected inside the fixed guide tube 18, and a guide funnel 20 fixedly connected to the top of the telescopic guide tube 19. The top of the telescopic guide tube 19 communicates with the bottom of the guide funnel 20. A return spring 21 is sleeved on the upper part of the outer wall of the telescopic guide tube 19. The upper and lower ends of the return spring 21 are fixedly connected to the bottom wall of the guide funnel 20 and the top outer wall of the fixed guide tube 18, respectively. A guide nozzle 111 corresponding to the position of the guide funnel 20 is provided at the top right end of the pouring cylinder 11. The bottom end of the fixed guide tube 18 extends into the pouring collection box 14. Adjustment mechanisms for tilting the pouring cylinder 11 are provided on the two support frames 16. The adjustment mechanism includes a main... The driving gear 22 and the driven gear 23 that meshes with the driving gear 22 are fixedly installed on the left end of the outer wall of the pouring cylinder 11. The driven gear 23 and the mounting rod 17 are on the same axis. The middle position of the driving gear 22 is fixedly installed with the adjusting rotating rod 26 that is rotatably installed on the left end of the two support frames 16. The top rear end of the support plate 12 is fixedly installed with the mounting plate 24. The front wall of the mounting plate 24 is fixedly installed with the adjusting motor 25. The output end of the adjusting motor 25 is fixedly installed with the rear end of the adjusting rotating rod 26.

[0024] The working principle of this utility model is as follows: During use, the output end of the control and adjustment motor 25 drives the active gear 22 to rotate through the adjustment and rotation rod 26. This forces the passive gear 23, which meshes with the active gear 22, to drive the pouring cylinder 11 to rotate clockwise around the mounting rod 17. This causes the liquid metal inside the pouring cylinder 11 to be poured out through the guide nozzle 111 for pouring. Under its own gravity, the liquid metal passes through the guide funnel 20, the telescopic guide tube 19, and the fixed guide tube 18 in sequence before falling into the pouring collection box 14 and being guided into the molding cavity 13. During this process, the pouring cylinder 11 drives the guide nozzle 111 to rotate downwards, squeezing the top of the guide funnel 20 and forcing the guide funnel 20 to rotate downwards. The compression return spring 21 drives the telescopic guide tube 19 to move downwards and retract into the fixed guide tube 18, so that the position of the guide funnel 20 and the position of the guide nozzle 111 always correspond, realizing the limiting and guiding function of the equipment for liquid metal, so as to prevent liquid metal from spilling onto the outside of the pouring collection box 14 and causing safety impact, thus improving the practicality of the equipment. Compared with the chain traction method, since the chain itself is movable, it is difficult to provide stable support and limiting function for the pouring cylinder 11. However, this equipment drives the pouring cylinder 11 to rotate and tilt by meshing the active gear 22 and the passive gear 23, thus providing effective support and limiting effect for the placement of the pouring cylinder 11 and improving the overall structural stability of the equipment.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
