Description
Technical Field
[0001] This utility model relates to the field of steel ball processing technology, specifically to a wear-resistant steel ball casting mold. Background Technology
[0002] Wear-resistant steel balls, also known as wear-resistant media for grinding machines, are consumables mainly used for grinding materials to bring them to the required standards. Wear-resistant steel balls are widely used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical plants and other fields. Wear-resistant steel ball molds are special tools used to manufacture and shape wear-resistant steel balls.
[0003] Existing patent CN220049945U discloses a wear-resistant ball casting mold, including a middle mold, side molds, a limiting top plate, and a limiting bottom plate. Forming cavities are distributed sequentially from top to bottom on both sides of the middle mold and on the corresponding side of the side molds. These cavities are connected by flow channels distributed on both sides of the middle mold and the corresponding side molds, with both ends of the flow channels extending to the upper and lower ends of the corresponding middle or side molds. The bottom end of the assembly formed by the middle and side molds is engaged with the limiting bottom plate, and the top end is engaged with the limiting top plate. The pouring port at the top of the limiting top plate is connected to each flow channel. During casting, molten steel enters each flow channel through the pouring port. Because the temperature of the molten steel drops rapidly upon entry, the resulting wear-resistant balls have relatively low quality. Therefore, this portion of molten steel is discharged into the lowest flow channel, and then the molten steel sequentially fills the forming cavities, ensuring that each forming cavity is filled while simultaneously guaranteeing the quality of the resulting wear-resistant balls.
[0004] Based on the above patent search and combined with the casting molds in the existing technology, it was found that although the current casting molds can produce and process wear-resistant steel balls and remove the steel balls, the removed steel balls are usually at a relatively high temperature, and there are impurities on the outer surface of the steel balls, which require manual cleaning. Moreover, the steel balls lack a cushioning structure when falling, and the steel balls are easily damaged, thus reducing their practicality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6This utility model provides a technical solution: a wear-resistant steel ball casting mold, including a base 1, a worktable 11 fixedly connected to the top of the base 1, a cooling and cleaning component on the top of the base 1, and a protective component on the top of the base 1. The cooling and cleaning component includes a cooling box 21 fixedly connected to the top of the base 1, a bracket 22 fixedly connected to the top of the cooling box 21, a cylinder 23 fixedly connected to the top of the bracket 22, a connecting frame 24 fixedly connected to the bottom of the cylinder 23, a connecting plate 25 fixedly connected to the bottom of the connecting frame 24, a first motor 26 fixedly connected to the top of the connecting plate 25, a stirring shaft 27 fixedly connected to the output end of the first motor 26, and multiple components fixedly connected to the outside of the stirring shaft 27. Multiple brushes 28 are evenly arranged along the axis of the stirring shaft 27. Coolant can be added into the cooling tank 21. The cylinder 23 can push the connecting frame 24 and the connecting plate 25 to move vertically, thereby moving the brushes 28 into the cooling tank 21. The first motor 26 can drive the stirring shaft 27 to rotate, thereby rotating the brushes 28, which can agitate and cool the steel balls, clean the surface impurities of the steel balls, and prevent impurities from remaining. At the same time, the brushes 28 can be moved out of the cooling tank 21 for easy removal of the steel balls or cleaning of impurities in the cooling tank 21. Moving rods 61 are fixedly connected to the top two sides of the connecting plate 25, and moving openings 62 are opened on the top two sides of the bracket 22. The moving rod 61 is slidably connected to the moving port 62. The connecting plate 25 can drive the moving rod 61 to move vertically. The movement of the moving rod 61 can guide the vertical movement of the connecting plate 25, which can improve the stability of the movement of the brush 28, etc., and prevent it from tilting and affecting its normal movement. The top of the worktable 11 is provided with a slide groove 41, and a slider 42 is slidably connected in the slide groove 41. The top of the slider 42 is provided with an inclined rod 43, and the top of the inclined rod 43 is provided with a lower mold 44. Multiple rotating rods 45 are evenly arranged between the lower mold 44 and the worktable 11. A second motor 46 is fixedly connected to the back of the worktable 11. The output end of the second motor 46 is fixedly connected with a lead screw 47. The lead screw 47 is screwed to the slider 42. The inclined rod 43 is rotatably connected to the worktable 11. Its two ends are hinged to the slider 42 and the lower mold 44, respectively. The top of the rotating rod 45 is fixedly connected to the lower mold 44, and the bottom of the rotating rod 45 is hinged to the worktable 11. The second motor 46 can drive the lead screw 47 to rotate. The rotation of the lead screw 47 can push the inclined rod 43 to move, which in turn can push the lower mold 44 to rotate along the rotating rod 45, which can facilitate the release of steel balls in the lower mold 44 and improve demolding efficiency. The top of the worktable 11 is fixedly connected to the mounting frame 71, and the top of the mounting frame 71 is fixedly connected to the hydraulic cylinder 72. The output end of the hydraulic cylinder 72 is fixedly connected to the upper mold 73. The hydraulic cylinder 72 can push the upper mold 73 to move vertically, which can process the steel balls.
[0027] Please see Figure 1 , Figure 5 , Figure 6 as well as Figure 7The protective components include a drop box 31 fixedly connected to the top of the base 1, multiple protective grooves 32 evenly arranged on both sides of the bottom of the drop box 31, a protective rod 33 disposed in the protective groove 32, a buffer plate 34 fixedly connected to the top of the protective rod 33, a spring 35 sleeved on the outside of the protective rod 33, and a damper 36 disposed between the buffer plate 34 and the bottom of the drop box 31. The protective rod 33 is slidably connected to the protective groove 32, and the two ends of the spring 35 are fixedly connected to the bottom of the buffer plate 34 and the bottom of the drop box 31, respectively. The steel ball on the lower mold 44 can fall to the top of the buffer plate 34 in the drop box 31. The steel ball drives the buffer plate 34 to move downward, thereby squeezing the spring 35 to deform it. The damper 36 can slow down the falling steel ball and prevent it from being damaged by collision due to excessive speed, thus protecting the steel ball. A discharge pipe 81 is fixedly connected to one side of the falling box 31. The discharge pipe 81 is inclined and can facilitate the steel balls in the falling box 31 to fall into the cooling box 21 for cooling and cleaning. The top two sides of the buffer plate 34 are fixedly connected to the first guide plate 51 and the top of the buffer plate 34 is fixedly connected to the second guide plate 52. The first guide plate 51 is triangular in shape and the second guide plate 52 is arc-shaped. The two first guide plates 51 can gather the steel balls to the middle position, and the second guide plate 52 can gather the steel balls at the position of the discharge pipe 81, which can facilitate the steel balls to be discharged into the cooling box 21.
[0028] Working principle: During operation, cylinder 23 is activated, which pushes the connecting frame 24 downward. The downward movement of the connecting frame 24 causes the connecting plate 25 to move downward, which in turn causes the first motor 26 and the brush 28 to move downward, allowing the brush 28 to enter the cooling box 21. Hydraulic cylinder 72 is activated, which pushes the upper mold 73 downward, closing with the lower mold 44 to process the steel ball. After processing, the upper mold 73 resets, and the second motor 46 is activated, which drives the lead screw 47 to rotate. The rotation of the lead screw 47 causes the slider 42 to move, which in turn causes the inclined rod 43 to move. The movement of the inclined rod 43 pushes the lower mold 44 to rotate along the rotating rod 45, causing the steel ball to detach from the lower mold 44 and fall into the drop box 31. The second motor 46 reverses, causing the lower mold 44 to reset. At the same time, the steel ball can contact the buffer plate 34, which cushions the impact. The downward movement of the punch plate 34 causes the spring 35 to deform. The spring 35 and the damper 36 protect the steel ball from falling and getting damaged. The first guide plate 51 and the second guide plate 52 gather the steel ball, allowing it to be discharged into the cooling box 21 through the discharge pipe 81. The steel ball is cooled by the coolant in the cooling box 21. The start of the first motor 26 drives the stirring shaft 27 to rotate. The rotation of the stirring shaft 27 drives the brush 28 to rotate, which agitates the steel ball and cleans impurities from its surface. After cleaning, the start cylinder 23 moves the brush 28 upward, removing it from the cooling box 21. This completes the cleaning of impurities and the removal of the steel ball. The above describes the entire working process of the device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
