A ball slider 34 is rotatably installed on the ball slider 34, and a rotating shaft 35 is rotatably installed on the ball slider 34. The top of the rotating shaft 35 is connected to a square table 37, and the top of the square table 37 is connected to an electromagnet 38. After the electromagnet 38 is started, the electromagnet 38 uses magnetic force to adsorb the mold tail cover on the surface of the electromagnet 38. The two support rods 310 are subjected to the downward pressure of the mold tail cover and enter the two long grooves of the electromagnet 38. At this time, the mold tail cover fits the top surface of the electromagnet 38, achieving the effect of fixing the mold tail cover; the outer wall of the screw rod 33 is provided with a threaded groove, and the inner wall of the ball slider 34 is slidably connected to the screw rod 33 through the ball, the square table 37 contacts the slide groove on the mounting cover 31, and the motor 32 is started. The motor 32 first rotates forward, and the motor 32 drives the screw rod 33 to rotate. When the screw rod 33 rotates, the cooperation between the thread groove and the ball drives the ball slider 34 to move left. When the ball slider 34 moves to the left, the motor 32 switches to reverse rotation, so that the ball slider 34 moves right. The outer wall of the rotating shaft 35 is connected to four arc rods 36, and the inner wall of the mounting cover 31 is installed with a short rod 311. The short rod 311 is hinged with a lever 312. A spring piece 313 is connected between the short rod 311 and the lever 312. The four arc rods 36 are arranged in a circular array with the center of the rotating shaft 35 as the center. The four arc rods 36 contact with the lever 312 in turn during the movement. When the table 37 contacts the slide groove on the mounting cover 31, the square table 37 cannot rotate. When the ball slider 34 moves to the left, after the square table 37 enters the circular groove, one of the arc rods 36 on the rotating shaft 35 contacts the lever 312. The lever 312 drives the rotating shaft 35 to rotate ninety degrees by shifting the arc rod 36. When the square table 37 enters the slide groove again, the slide groove limits the square table 37 to prevent the square table 37 from rotating during processing, thereby achieving the effect that the electromagnet 38 can rotate ninety degrees every time it performs a reciprocating motion. The electromagnet 38 can drive the four edges of the end face of the mold tail cover to grind in turn through four reciprocating motions, and the automation efficiency is high.The outer wall of the electromagnet 38 is connected to four protrusions 39, and two support rods 310 are installed on the four protrusions 39 through springs. The electromagnet 38 is provided with two long grooves, and the two support rods 310 match the two long grooves of the electromagnet 38 in size. When the electromagnet 38 is turned off, the electromagnet 38 loses its magnetic attraction to the mold tail cover, and the two support rods 310 are reset upward by the elastic force of the springs on the protrusions 39, so that the two support rods 310 prop up the mold tail cover upward. After the mold tail cover is propped up, it is convenient for the staff to hold the bottom and take it; through the setting of the displacement component 3, after the staff uses the electromagnet 38 to fix the mold tail cover, the electromagnet 38 can use the left and right The reciprocating movement drives the mold tail cover to continuously contact the grinding wheel of the grinder 2, thereby performing grinding processing. Each time the electromagnet 38 reciprocates left and right, it can rotate 90 degrees, so that the four sides of the end of the mold tail cover contact the grinding wheel in turn, achieving the effect of automatic cycle processing, reducing the steps for the staff to readjust the processing position, and the four-side cycle processing makes the flatness of the end surface of the mold tail cover more uniform, and improves the fit between the mold tail cover and the mold; through the setting of the two support rods 310, the mold tail cover can be supported by the two support rods 310 after the processing is completed, which is convenient for the staff to hold the bottom and take the mold tail cover. ;

[0040] For further information, see Figure 7 - Fig.11The cooling assembly 4 is used to cool the mold tail cover. The cooling assembly 4 is arranged on the operating table 1. The cooling assembly 4 includes a mounting frame 41. The mounting frame 41 is mounted on the operating table 1. A cooling plate 42 is mounted on the mounting frame 41 through a spring. The inner wall of the cooling plate 42 is connected to a cooling pipe 43. The edge opposite to the edge being ground contacts the cooling plate 42 on the mounting frame 41. The cooling plate 42 applies a certain pressure to the mold tail cover by the elastic force of the spring. The cooling pipe 43 in the cooling plate 42 cools the cooling plate 42. The cooling plate 42 cools the mold tail cover by contacting with the mold tail cover to prevent the surface temperature of the mold tail cover from being too high after multiple grinding processes. The two ends of the cooling pipe 43 are respectively connected with hoses. 44, a water tank 45 and a water pump 46 are installed on the operating table 1, and a water inlet 461 and a water outlet 462 are arranged on the water pump 46, the water inlet 461 is connected to the water tank 45, the water outlet 462 is connected to one of the hoses 44, and the water tank 45 is connected to the other hose 44, an inner shaft 47 is rotatably installed on the inner wall of the water pump 46, and three arc-shaped pieces 48 are hinged on the outer wall of the inner shaft 47, and an annular groove is arranged on the inner wall of the water pump 46, and one end of the arc-shaped piece 48 away from the inner shaft 47 is slidably connected with the annular groove, and the annular groove on the inner wall of the water pump 46 has a limiting effect on one end of the arc-shaped piece 48, and the two sides of the arc-shaped piece 48 are in contact with the inner walls of the front and rear sides of the water pump 46, and the connection between the inner shaft 47 and the water pump 46 is The contact point is eccentrically arranged, and a connecting shaft 49 is rotatably installed on the inner wall of the mounting cover 31. One end of the connecting shaft 49 is connected to the inner shaft 47, and the other end of the connecting shaft 49 is rotatably connected to a gear ring 410. A rack 411 is connected to the outer wall of the ball slider 34, and the rack 411 meshes with the gear ring 410 during movement. A ratchet is arranged on the inner wall of the gear ring 410, and two pawls are arranged on the outer wall of the connecting shaft 49. Both pawls are in contact with the ratchet. The ratchet in the gear ring 410 cooperates with the two pawls on the connecting shaft 49, so that the gear ring 410 can drive the connecting shaft 49 to rotate when it rotates clockwise, and the gear ring 410 rotates by itself when it rotates counterclockwise without driving the connecting shaft 49 to rotate. The three arc-shaped pieces 48 are realized by cooperation The effect of pumping the coolant allows the coolant in the cooling pipe 43 to circulate and maintain the cooling effect of the cooling pipe 43. The outer wall of the water tank 45 is provided with a plurality of heat sinks to accelerate the heat dissipation of the coolant in the water tank 45. Through the setting of the cooling component 4, during the processing of the mold tail cover, one of the edges can achieve the effect of cooling down by contacting with the cooling plate 42, so as to avoid scalding the hands of the staff when taking it. Through the cooperation of the three arc-shaped pieces 48 and the water pump 46, the effect of the coolant in the cooling pipe 43 being able to circulate is achieved, and the coolant that absorbs the heat flows into the water tank 45 for cooling and reuse. The coolant in the cooling pipe 43 always maintains a low temperature to maintain the cooling effect.

[0041] Further, see Fig.12 - Fig.13The coating assembly 5 is used to apply grinding liquid on the mold tail cover. The coating assembly 5 is arranged on the operating table 1. The coating assembly 5 includes an adjustment frame 51. An adjustment rod 52 is slidably mounted on the adjustment frame 51. The adjustment rod 52 can adjust the height on the adjustment frame 51. A coating box 53 is connected to the adjustment rod 52. A plurality of bristles 54 are connected to the bottom of the coating box 53. The coating box 53 is provided with a plurality of leakage holes. The grinding liquid in the coating box 53 penetrates into the plurality of bristles 54 through the plurality of leakage holes, and the grinding is about to be performed. The edge to be ground comes into contact with a plurality of brushes 54, and the plurality of brushes 54 apply the grinding fluid to the mold tail cover, so that the edge of the mold tail cover to be ground is coated with the grinding fluid. The grinding fluid can help the mold tail cover obtain a smoother surface during the grinding process, reduce the surface roughness, and improve the appearance and performance of the product; a replenishing box 56 is installed on the operating table 1, and an air pipe 57 and a liquid pipe 55 are installed on the replenishing box 56. The end of the liquid pipe 55 away from the replenishing box 56 is connected to the coating liquid box 53, and the inner part of the mounting cover 31 is connected to the inner part of the mounting cover 31. The wall is provided with an air bag 58, and one end of the air pipe 57 away from the supplementary box 56 is connected to the air bag 58, and a semicircular block 59 is connected to the air bag 58. The outer wall of the ball slider 34 is connected to a resistance block 510, and the resistance block 510 contacts the semicircular block 59 during the movement. After the air bag 58 is squeezed, air is injected into the supplementary box 56 through the air pipe 57. The supplementary box 56 is also filled with grinding fluid. The supplementary box 56 uses the positive pressure principle to transport the coolant to the coating liquid box 53 through the liquid pipe 55, and the coating liquid box 53 is pressed. The grinding fluid can be replenished, and it can be replenished automatically in small amounts multiple times, which reduces the operation of the staff to replenish the grinding fluid; through the setting of the coating component 5, before the edge of the end face of the mold tail cover is ground, multiple bristles 54 apply the grinding fluid on the edge, thereby improving the smoothness of the grinding process, improving the appearance quality and sealing performance; through the setting of the replenishment box 56, the replenishment box 56 can automatically replenish the grinding fluid into the coating box 53 through the liquid pipe 55, reducing the operating steps of the staff.

[0042] With the above structure, the working principle of this case is that the staff places the mold tail cover on the two support rods 310, and after starting the electromagnet 38, the electromagnet 38 uses magnetic force to adsorb the mold tail cover on the surface of the electromagnet 38, and the two support rods 310 are subjected to the downward pressure of the mold tail cover and enter the two long grooves of the electromagnet 38. At this time, the mold tail cover fits the top surface of the electromagnet 38, thereby achieving the function of fixing the mold tail cover; after starting the motor 32, it first rotates forward, and the motor 32 drives the screw rod 33 to rotate. When the screw rod 33 rotates, the ball slider 34 is driven to move to the left through the cooperation of the thread groove and the ball. When the ball slider 34 moves to the left and is in place, the motor 32 switches to reverse rotation, so that the ball slider 34 turns to move to the right. The motor 32 repeatedly switches the rotation direction, so that the ball slider 34 can move back and forth left and right. The grinding wheel on the grinder 2 can adjust its height according to the processing requirements. After the grinder 2 is started, the grinding wheel rotates. During the reciprocating movement of the ball slider 34, the ball slider 34 drives the square table 37 to move back and forth left and right through the rotating shaft 35. The square table 37 drives the electromagnet 38 to move synchronously. The side of the mold tail cover end face above the electromagnet 38 close to the grinding wheel contacts the grinding wheel during movement. The grinding wheel grinds the end face of the mold tail cover in motion by rotation. When the square table 37 contacts the slide groove on the mounting cover 31, the square table 37 cannot rotate. During the movement of the ball slider 34 to the left, after the square table 37 enters the circular groove, One of the arc rods 36 on the shaft 35 contacts the lever 312, and the lever 312 moves the arc rod 36, so that the arc rod 36 drives the shaft 35 to rotate. When the shaft 35 rotates 90 degrees, the arc rod 36 is out of contact with the lever 312. At this time, the electromagnet 38 rotates 90 degrees with the square table 37. When the ball slider 34 turns to move rightward, the arc surface on the lever 312 contacts one of the arc rods 36. Since a limiting mechanism is provided at the hinge position of the lever 312 and the short rod 311, the lever 312 can swing to the right but cannot swing to the left. The lever 312 swings to the right after being pushed to the right by the arc rod 36. When the arc rod 36 is not in contact with the lever 312, the lever 312 uses the spring sheet 31 3 is reset by the elastic force of the square table 3. During this process, the rotating shaft 35 does not rotate. When the square table 37 enters the slide slot again, the slide slot limits the square table 37 to prevent the square table 37 from rotating during processing, thereby achieving the effect that the electromagnet 38 can rotate 90 degrees every time it performs a reciprocating motion. The electromagnet 38 can drive the four edges of the end face of the mold tail cover to perform grinding processing in sequence through four reciprocating motions, and the automation efficiency is high; when the grinding processing is completed, the electromagnet 38 is turned off, the electromagnet 38 loses the magnetic attraction to the mold tail cover, and the two support rods 310 use the elastic force of the spring on the protrusion 39 to reset upward, so that the two support rods 310 support the mold tail cover upward. After the mold tail cover is supported, it is convenient for the staff to hold the bottom and take it;By setting the displacement assembly 3, after the staff fixes the mold tail cover with the electromagnet 38, the electromagnet 38 can use the left and right reciprocating movement to drive the mold tail cover to continuously contact the grinding wheel of the grinder 2, so as to perform grinding processing. Each time the electromagnet 38 reciprocates left and right, it can rotate 90 degrees, so that the four edges of the end of the mold tail cover contact the grinding wheel in turn, achieving the effect of automatic cycle processing, reducing the steps for the staff to readjust the processing position, and the four-side cycle processing makes the flatness of the end surface of the mold tail cover more uniform, and improves the fit between the mold tail cover and the mold; by setting the two support rods 310, the mold tail cover can be supported by the two support rods 310 after the processing is completed, which is convenient for the staff to hold the bottom and take the mold tail cover. ;

[0043] The cooling pipe 43, the two hoses 44, the water tank 45 and the pump 46 are filled with cooling liquid. When the mold tail cover moves following the electromagnet 38, the edge opposite to the edge being ground contacts the cooling plate 42 on the mounting frame 41. The cooling plate 42 applies a certain pressure to the mold tail cover by the elastic force of the spring. The cooling pipe 43 in the cooling plate 42 cools the cooling plate 42. The cooling plate 42 cools the mold tail cover by contacting with the mold tail cover to avoid the mold tail cover from having an excessively high surface temperature after multiple grinding processes. The rack 411 moves synchronously following the ball slider 34. The rack 411 contacts the gear ring 410 when moving. Due to the cooperation between the ratchet in the gear ring 410 and the two ratchets on the connecting shaft 49, , so that the gear ring 410 can drive the connecting shaft 49 to rotate when it rotates clockwise, and the gear ring 410 rotates by itself when it rotates counterclockwise without driving the connecting shaft 49 to rotate. The rack 411 drives the gear ring 410 to rotate clockwise when it moves to the left, and drives the gear ring 410 to rotate counterclockwise when it moves to the right. When the connecting shaft 49 rotates, it drives the inner shaft 47 to rotate, and the inner shaft 47 drives the three arc-shaped pieces 48 to rotate. The two sides of the arc-shaped pieces 48 are in contact with the inner walls of the front and rear sides of the water pumping cylinder 46. Since the inner shaft 47 is eccentrically arranged and the annular groove on the inner wall of the water pumping cylinder 46 has a limiting effect on one end of the arc-shaped piece 48, the arc-shaped piece 48 repeatedly moves away from the inner shaft 47 and in contact with the inner shaft 47 during the rotation process. When the arc piece 48 moves to the water inlet 461, the arc piece 48 swings in the direction away from the inner shaft 47, so that the space between the arc piece 48 and the inner shaft 47 increases, and the coolant in the water tank 45 is pumped into the water pumping cylinder 46 through the water inlet 461 by using the negative pressure principle. When the arc piece 48 moves to the water outlet 462, the arc piece 48 swings in the direction close to the inner shaft 47, so that the space between the arc piece 48 and the inner shaft 47 decreases, and the water in the water pumping cylinder 46 is squeezed into the hose 44 through the water outlet 462 by using the positive pressure principle. The hose 44 transports the water to the cooling pipe 43, and the water in the cooling pipe 43 is transported to the water tank 45 through another hose 44. The three arc pieces 48 are realized by cooperation The cooling liquid is pumped out so that the cooling liquid in the cooling pipe 43 can circulate and maintain the cooling effect of the cooling pipe 43. The outer wall of the water tank 45 is provided with a plurality of heat sinks to accelerate the heat dissipation of the cooling liquid in the water tank 45. Through the setting of the cooling assembly 4, during the processing of the mold tail cover, one of the edges can achieve the effect of cooling down by contacting with the cooling plate 42, so as to avoid scalding the hands of the staff when taking it. Through the cooperation of the three arc-shaped pieces 48 and the water pump 46, the cooling liquid in the cooling pipe 43 can circulate and the cooling liquid that absorbs the heat flows into the water tank 45 for cooling and reuse. The cooling liquid in the cooling pipe 43 always maintains a low temperature to maintain the cooling effect.

[0044] The coating box 53 is filled with grinding liquid, and the adjustment rod 52 can adjust the height on the adjustment frame 51 to ensure that the bristles 54 are located on the movement trajectory of the mold tail cover. When the mold tail cover moves to the leftmost side and starts to rotate, the edge to be ground comes into contact with multiple bristles 54, and the grinding liquid in the coating box 53 penetrates into the multiple bristles 54 through multiple leakage holes. The multiple bristles 54 apply the grinding liquid to the mold tail cover, so that the edge of the mold tail cover to be ground is coated with grinding liquid. The grinding liquid can help the mold tail cover obtain a smoother surface during the grinding process, reduce surface roughness, and improve the appearance and performance of the product; the resistance block 510 follows the movement of the ball slider 34, and the resistance block 510 contacts the semicircular block 59 during the movement, so that the resistance block 510 moves the semicircular block 59 along the arc surface of the semicircular block 59 Pushing backward, the semicircular block 59 squeezes the airbag 58 when moving backward. After being squeezed, the airbag 58 injects air into the replenishing box 56 through the air pipe 57. The replenishing box 56 is also filled with grinding fluid. The replenishing box 56 uses the positive pressure principle to transport the coolant to the coating box 53 through the liquid pipe 55, and replenishes the grinding fluid in the coating box 53. It automatically replenishes small amounts multiple times, which reduces the operation of staff to replenish the grinding fluid; through the setting of the coating component 5, before the edge of the end face of the mold tail cover is ground, multiple bristles 54 apply the grinding fluid to the edge, thereby improving the smoothness of the grinding process, improving the appearance quality and the sealing performance; through the setting of the replenishing box 56, the replenishing box 56 can automatically replenish the grinding fluid into the coating box 53 through the liquid pipe 55, reducing the operating steps of the staff.
