[0011] Compared with the prior art, the mold for a wear-resistant ball production line provided by the utility model has at least the following beneficial effects:

[0012] (1) Through the setting of the ejection mechanism, when the mold is closed, the spring is subjected to the downward pressure exerted on the movable plate by the upper mold through the positioning column, and the spring begins to contract. After the mold is poured, the mold is separated and the upper mold is lifted upward. At this time, the spring begins to release elastic potential energy without being affected by external forces. The spring drives the positioning column and the ejector pin to move upward. The ejector block at the top of the ejector pin ejects the grinding ball from the mold cavity to complete the demolding of the grinding ball. In this way, the grinding ball can be lifted up by the ejection mechanism during the demolding process to achieve the purpose of demolding.

[0013] (2) Through the setting of the feeding device, when the mold is separated, the spring mentioned above begins to release its elastic potential energy to push the grinding ball out. At the same time, the spring releases its elastic potential energy and pushes the push block upward. During the upward movement of the push block, it is blocked by the fixed block. The push block pushes the fixed block upward, but the sliders on both sides of the receiving hopper integrated with the fixed block are inserted in the slide groove. At this time, the fixed block is subjected to the force of the push block, which is converted into an oblique upward force. The receiving hopper moves along the slide. After the mold is separated, the feeding device moves to one side of the grinding ball, which can just catch the grinding ball pushed out by the pushing device. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 A mold for a wear-resistant ball production line, comprising an upper mold 1 and a lower mold 2 arranged below the upper mold 1, wherein the upper mold 1 is provided with a mold cavity 10, and the lower mold 2 is provided with a casting mold cavity corresponding to the mold cavity 10, and a pouring port connected to the casting mold cavity is opened on the top surface of the upper mold 1, and an inner cavity 19 located below the mold cavity 10 is provided in the inner wall of the lower mold 2, and an ejection mechanism is provided in the inner cavity 19;

[0020] Through the setting of the ejection mechanism, after the casting is completed, the ejection mechanism can eject the grinding balls in the film cavity, so that the grinding balls adhere to the mold cavity and the grinding balls are quickly demolded.

[0021] Further, see Figure 1-3 It is worth noting that the ejection mechanism includes a movable plate 16 slidably disposed in the inner cavity 19, an ejector pin 18 vertically fixed on the top surface of the movable plate 16, and an ejector block 8 slidably disposed in the mold cavity 10. A circular groove 20 for accommodating the ejector block 8 is provided on the inner wall of the mold cavity 10. The circular groove 20 is connected to the interior of the inner cavity 19. The end of the ejector pin 18 passes through the circular groove 20 and is fixed to the ejector block 8. A plurality of springs 15 are fixed between the bottom end of the movable plate 16 and the inner wall of the bottom end of the inner cavity 19.

[0022] The four corners of the top surface of the lower mold 2 are all provided with through holes 7, and positioning posts 17 are provided in the through holes 7. The positioning posts 17 penetrate into the inner cavity 19 and are fixed to the movable plate 16;

[0023] Through the setting of the ejection mechanism, when the mold is closed, the spring 15 is subjected to the downward pressure exerted on the movable plate 16 by the upper mold 1 through the positioning column 17, and the spring 15 begins to shrink. After the mold casting is completed, the mold is separated and the upper mold 1 is lifted upward. At this time, the spring 15 begins to release elastic potential energy without being affected by external force. The spring 15 drives the positioning column 17 and the ejector pin 18 to move upward. The ejector block 8 at the top of the ejector pin 18 ejects the grinding ball from the mold cavity to complete the demolding of the grinding ball, so that the grinding ball can be lifted by the ejection mechanism during the demolding process to achieve the purpose of demolding.

[0024] In actual use, the grinding balls will adhere to the top block 8 when demoulding, which makes it troublesome and laborious to manually take them out;

[0025] Further, see Figure 2 As shown, it is worth noting that a material pushing device is provided on one side of the lower die 2;

[0026] The pushing device comprises a pushing platform 3 arranged on the side of the lower mold 2, a fixing platform 4 is arranged on the top surface of the pushing platform 3, a cylinder 5 is arranged on the fixing platform 4, the output end of the cylinder 5 faces the lower mold 2, and a pushing block 6 is fixed at the output of the cylinder 5;

[0027] Through the setting of the pushing device, after the grinding ball is pushed out of the mold cavity 10 by the ejection mechanism, the output end of the cylinder 5 begins to push back in the direction where the grinding ball is located, so that the pushing block 6 contacts the grinding ball and pushes the grinding ball out, so that the grinding ball rolls into the conveyor belt and enters the next production step, which solves the problem of adhesion between the grinding ball and the ejector rod, and also realizes automatic removal of the grinding ball, reducing the time of manual removal.

[0028] Further, refer to Figure 1-3 , a material receiving device is provided on the other side of the lower mold 2;

[0029] The material receiving device includes an inclined receiving hopper 9, an inclined chute is provided on one side of the top surface of the lower mold 2, the receiving hopper 9 is slidably arranged in the inclined chute, and a square hole 12 connected to the inner cavity 19 is provided on the inner wall of the bottom surface of the chute, a fixed block 13 is fixed on the bottom surface of the receiving hopper 9, the end of the fixed block 13 penetrates into the square hole 12, and the end of the fixed block 13 is inclined away from the side of the pushing platform 3, and a right-angled trapezoidal push block 14 is also fixed on the top surface of the movable plate 16, the end of the push block 14 penetrates into the square hole 12, and the inclined side of the push block 14 abuts against the inclined surface of the fixed block 13;

[0030] Slide grooves 11 are provided on both sides of the upper slide groove of the lower mold 2, and sliding blocks matching the slide grooves 11 are provided on the outer walls of both sides of the receiving hopper 9;

[0031] The upper end of the receiving hopper 9 is parallel to the top surface of the lower mold 2;

[0032] Through the setting of the feeding device, when the mold is separated, the spring 15 mentioned above begins to release elastic potential energy to push the grinding balls out. While releasing the elastic potential energy, the spring 15 also pushes the thrust block 14 upward. During the upward movement of the thrust block 14, it is blocked by the fixed block 13. The thrust block 14 pushes the fixed block 13 upward, but the sliders on both sides of the receiving hopper 9 integrated with the fixed block 13 are inserted in the slide groove 11. At this time, the fixed block 13 is subjected to the force of the thrust block 14, which will be converted into an oblique upward force. The receiving hopper 9 will move along the slide. After the mold is separated, the feeding device moves to one side of the grinding ball, which can just catch the grinding ball pushed out by the pushing device.
