DETAILED DESCRIPTION

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1-4As shown, a demoulding device for producing wear-resistant steel balls comprises a collecting box 1 with an open end, a lower template 2 arranged in the open end of the collecting box 1, a support frame 3 fixed on the open end of the collecting box 1 in an inverted U shape, and an upper template 4 slidably arranged in the inner side of the support frame 3, a first cylinder 5 is installed on the top of the support frame 3, a telescopic rod of the first cylinder 5 penetrates the support frame 3 and is fixedly connected to the upper template 4, a hemispherical molding groove is provided on the bottom surface of the upper template 4 and the lower template 2, and a pouring port connected to the hemispherical molding groove is provided on the top surface of the upper template 4;

[0025] When in use, the lower template 2 is flipped in advance so that the hemispherical molding groove on the lower template 2 corresponds to the hemispherical molding groove on the upper template 4, and then the first cylinder 5 is turned on to push the upper template 4 to move downward, so that the upper template 4 and the lower template 2 are closed, so that the hemispherical molding grooves on the upper template 4 and the lower template 2 are combined to form a spherical cavity, and then molten iron is injected into the spherical cavity from the pouring port, and the molten iron can be cooled in the spherical cavity to form grinding balls.

[0026] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that it also includes a shedding mechanism for facilitating the demoulding of the grinding balls, and the shedding mechanism includes a flap component, a shaking component and a shock component;

[0027] The flap component includes a transmission rod 6 which is transversely arranged in the inner cavity of the collection box 1, and the lower template 2 is tightly sleeved on the rod body of the transmission rod 6. Both sides of the collection box 1 are vertically provided with track limiting slideways 7 adapted to the transmission rod 6. The two ends of the transmission rod 6 slide through the corresponding track limiting slideways 7 respectively, and the transmission rod 6 is rotatably sleeved on the rod body of the collection box 1, and a rotating ring plate 8 is rotatably sleeved on one of the rotating ring plates 8 through a bracket, and the output shaft of the motor 9 is fixedly connected to one end of the transmission rod 6;

[0028] A sieve plate 10 is provided at the bottom of the inner side of the collecting box 1, and a vibrator 11 is installed on the sieve plate 10. A material taking window is provided at the bottom of one side wall of the collecting box 1, and a sealing plate 12 hingedly connected to the outer wall of the collecting box 1 is provided outside the material taking window.

[0029] After the grinding balls are cooled and formed, the first cylinder 5 is turned on to separate the upper template 4 from the lower template 2, and then the motor 9 is turned on. The output shaft of the motor 9 can drive the transmission rod 6 and the lower template 2 as a whole, so that the hemispherical molding groove on the lower template 2 is inverted, and the formed grinding balls can fall on the sieve plate 10. Then the vibrator 11 is turned on to make the vibrator 11 vibrate continuously, so as to effectively screen the falling materials, so that the grinding balls are retained on the sieve plate 10, and the residues are separated and fall to the inner wall of the bottom end of the collecting box 1. Later, only the sealing plate 12 needs to be opened to facilitate the removal of the grinding balls and the residues.

[0030] Further, refer to Figure 1 As shown, it is worth noting that the shaking component includes a support base 14 vertically fixed on the side wall of the collection box 1 and a second cylinder 13 vertically mounted on the support base 14, and the telescopic end of the second cylinder 13 is fixedly connected to the outer wall of the rotating ring plate 8;

[0031] By setting the shaking component, after the lower template 2 is flipped by the flap component, the telescopic end of the second cylinder 13 in the shaking component can carry the rotating ring plate 8 to perform reciprocating lifting and sliding, thereby achieving the effect of continuous up and down shaking of the lower template 2, and utilizing the shaking method to accelerate the falling rate of the grinding balls in the hemispherical molding groove of the lower template 2.

[0032] Further, refer to Figure 1-3 As shown, it is worth noting that the shock component includes a movable seat 15 slidably arranged on one side of the top surface of the lower template 2 in a C-shape, a spline shaft 17 transversely arranged on the outside of the movable seat 15, a transmission rod 18 fixed to one end of the spline shaft 17, and a spline sleeve 16 slidably arranged on the rod body of the other end of the spline shaft 17, two ball rods 19 are symmetrically fixed on the rod body of the transmission rod 18, one of the ball rods 19 is in contact with the top surface of the lower template 2, the end of the transmission rod 18 is rotatably sleeved with a rotating seat 20, and the rotating seat 20 is vertically fixed on the top surface of the lower template 2, the spline sleeve 16 rotates and penetrates into the inner side of the movable seat 15, and a power component for providing rotational force for the spline sleeve 16 is arranged in the movable seat 15;

[0033] By setting the shock component, when the lower template 2 is continuously shaken up and down by the shaking component, the power component in the shock component can provide intermittent rotational force to the spline sleeve 16 in real time, so that the two ball rods 19 on the transmission rod 18 can intermittently knock the lower template 2, further improving the shedding effect of the grinding balls.

[0034] Further, refer to Figure 2-4 As shown, it is worth noting that the power assembly includes an active rod 21 that is laterally rotatably arranged between the inner walls on both sides of the movable seat 15 and a transmission gear 22 that is tightly sleeved on the rod body of the active rod 21. The end of the spline sleeve 16 away from the spline shaft 17 is connected to the rod body of the active rod 21 through a bevel gear transmission. A mounting groove 23 is vertically opened on the inner side wall of the collection box 1 facing the active rod 21. A plurality of transmission tooth plates 24 that mesh with the transmission gear 22 are equidistantly fixed on the inner wall of the innermost side of the mounting groove 23.

[0035] A fixing sleeve 25 is sleeved on the rod body of the active rod 21 and fixed perpendicularly to the inner wall of the movable seat 15. A torsion spring 26 is sleeved on the rod body of the active rod 21 located inside the fixing sleeve 25. One end of the torsion spring 26 is fixedly connected to the inner wall of the fixing sleeve 25, and the other end of the torsion spring 26 is fixedly connected to the inner wall of the movable seat 15.

[0036] During the reciprocating lifting and lowering movement of the lower template 2 under the action of the shaking component, the transmission gear 22 in the power assembly can slide into the installation groove 23 and intermittently engage with several transmission tooth plates 24 to provide intermittent rotational force for the active rod 21. During this period, when the active rod 21 is rotated under force, the active rod 21 can be synchronously driven by the bevel gear to the spline sleeve 16, the spline shaft 17 and the transmission rod 18 as a whole, so that the transmission rod 18 rotates forward, and one of the ball rods 19 is acted on to knock the lower template 2. In the process, the active rod 21 can be synchronized with the inner side of the fixed sleeve 25 to twist the torsion spring 26, so that the torsion spring 26 is deformed. In this way, the elastic force of the torsion spring 26 is used. When the transmission gear 22 moves to a position where it is not engaged with the transmission tooth plate 24, the active rod 21 automatically reverses. Similarly, the spline sleeve 16, the spline shaft 17 and the transmission rod 18 reverse as a whole, and another ball rod 19 is acted on to knock the lower template 2.

[0037] Further, refer to Figure 3 As shown, it is worth noting that a screw rod 28 is vertically rotatably connected to the outer wall of the movable seat 15 away from the transmission tooth plate 24, and a nut seat 29 vertically fixed to the top surface of the lower template 2 is threadedly connected to the rod body of the screw rod 28, and two slide bars 27 are symmetrically fixed to the top surface of the lower template 2, and a slide groove adapted to the slide bar 27 is opened at the bottom end of the movable seat 15;

[0038] By setting the screw rod 28 and the nut seat 29, when the lower template 2 and the movable seat 15 are rotated as a whole by the flap component, the screw rod 28 can be turned in advance, so that the screw rod 28 is retracted in the inner wall of the nut seat 29 under the threaded structure and pulls the movable seat 15 to slide, so that the movable seat 15, the active rod 21 and the transmission gear 22 are away from the inner wall of the collection box 1 as a whole, thereby preventing the transmission gear 22 from contacting the inner wall of the collection box 1 when the lower template 2 rotates to cause movement obstruction;

[0039] In addition, during the sliding process of the movable seat 15, the spline sleeve 16 can synchronously slide along the shaft of the spline shaft 17, so that the movable seat 15 can slide flexibly without affecting the overall rotation effect of the spline shaft 17 and the spline sleeve 16.

[0040] In addition, by providing the slide bar 27 and the slide groove, the moving track of the movable seat 15 can be further limited when the movable seat 15 slides, thereby ensuring the smoothness of the sliding of the movable seat 15.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model.
