Description

Technical Field

[0001] This invention relates to the field of grinding equipment, and more particularly to a grinding machine and method for mold production and processing. Background Technology

[0002] A grinding machine is a device that uses abrasive tools to grind the surface of a workpiece, thereby improving the smoothness of the workpiece surface. Grinding machines are frequently used for the initial grinding of some mold components, such as ejector pins.

[0003] However, when machining long ejector pins, existing grinding machines can only grind the outer surface of the ejector pin or the end face of the ejector pin boss separately. When grinding the outer circle and end face of the ejector pin at the same time, it is necessary to change equipment or clamp multiple times, which is cumbersome and makes grinding inconvenient. In addition, the grinding machine fixture will block the outer surface of the ejector pin after clamping it, causing grinding interference and affecting the smoothness of grinding. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a grinding machine and method for mold production and processing.

[0008] Preferably, the clamping and pushing component includes a servo slide fixedly installed at the rear edge of the lower inner end face of the equipment housing. A pushing frame is fixedly installed on the slide of the servo slide. An I-shaped frame is elastically installed on the side of the pushing frame. A prism is fixedly installed through both ends of the I-shaped frame. Two secondary sleeves are symmetrically slidably installed on the outer surface of one of the prisms. A rod clamp is fixedly installed at the opposite ends of the two secondary sleeves. Two main sleeves are symmetrically slidably installed on the outer surface of the other prism. A boss clamp is fixedly installed at the opposite ends of the two main sleeves. Rollers are installed at the rear ends of the secondary sleeves and the rear ends of the main sleeves. A magnet is installed through the inner surface of the lower boss clamp.

[0009] Preferably, two bending frames are symmetrically fixedly installed on the lower inner surface of the equipment housing behind the servo slide. Two trapezoidal frames are symmetrically arranged on the sides of the bending frames. The trapezoidal frames are fixed to the equipment housing. A positioning cap is fixedly installed at the lower end of the I-beam frame. A positioning support column is arranged on the side of the positioning cap. The positioning support column is fixed to the equipment housing. A sub-frame is slidably installed on the outer surface of the slide. A lever is slidably installed on the side of the sub-frame. A pusher frame is rotatably installed at the end of the lever. The end of the pusher frame is rotatably connected to the slide. A control frame is fixedly installed at the front end of the pusher frame.

[0010] Preferably, a guide rod is slidably mounted on the upper end of the sub-frame, the end of the guide rod is fixed to the slide, and a second return spring is wound around the outside of the guide rod, with both ends of the second return spring fixed to the slide and the sub-frame respectively.

[0011] Preferably, a first return spring is wound around the outer side of each of the two prisms, with the two ends of one of the first return springs fixed to the two secondary sleeves respectively, and the two ends of the other first return spring fixed to the two main sleeves respectively.

[0012] Preferably, two guide posts are slidably installed through the side of the pusher frame. The ends of the guide posts are fixed to the I-shaped frame. A spring body is wound around the outside of the guide posts. The two ends of the spring body are fixed to the pusher frame and the I-shaped frame, respectively.

[0013] A method for using a grinding machine for mold production and processing is also provided, including the following steps:

[0014] S1: Place the ejector pin on the clamping pusher to clamp and push the ejector pin.

[0015] S2: At this time, the gear ring rotates, which drives the self-rotating No. 2 grinding wheel to rotate in a circle to grind the outer surface of the pushed ejector pin;

[0016] S3: After the outer surface of the ejector pin is ground, the clamping pusher will push the slide to move backward, which in turn will drive the rotating No. 1 grinding wheel to move backward to grind the boss end face of the ejector pin.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The rotating gear ring drives the self-rotating stepped No. 2 grinding wheel to rotate in a circle. The large-diameter section of the stepped No. 2 grinding wheel grinds the outer surface of the ejector pin, and the small-diameter section of the stepped No. 2 grinding wheel grinds the outer surface of the ejector pin's boss. After the outer surface is ground, the moving carriage drives the self-rotating No. 1 grinding wheel to move backward and grind the end face of the ejector pin's boss. This simultaneously completes the grinding of both the outer surface and the end face of the ejector pin. The process does not require equipment switching, effectively improving the convenience of grinding.

[0019] 2. Place the boss end of the ejector pin into the lower boss clamp. The magnet will attract the ejector pin to prevent it from falling. Then, the servo slide moves the pusher and the I-beam frame laterally to advance the ejector pin. During this process, the rollers on the main sleeve will roll along the inclined side of the trapezoidal frame, allowing the two boss clamps to move towards each other and clamp the ejector pin from the boss end. After clamping, the rollers on the main sleeve will roll to the horizontal section of the trapezoidal frame and continue to advance, allowing the clamped ejector pin to contact the second grinding wheel for grinding. When the outer surface of the ejector pin end is ground and extends from the grinding area, the rollers on the secondary sleeve will contact the inclined side of the bending frame and roll along it. This allows the two clamping sleeves to move towards each other, clamping the end of the ejector pin. After clamping, the roller on the secondary sleeve rolls to the horizontal section of the bending frame, while the roller on the main sleeve rolls to the inclined side of the trapezoidal frame on the other side. Then, as the process continues, the roller on the main sleeve rolls along the inclined side of the trapezoidal frame under the elastic force of the first return spring, allowing the two boss clamping sleeves to separate and loosen the clamping on the boss end of the ejector pin, exposing the boss end of the ejector pin for grinding by the second grinding wheel. During the grinding process, the second grinding wheel can automatically change the clamping position on the ejector pin, allowing the outer surface of the ejector pin to be fully exposed, so that the grinding is not hindered, thereby improving the smoothness of the grinding.

[0020] 3. After the outer surface of the ejector pin is ground, the positioning cap is pressed tightly against the positioning support column to position the I-beam frame and keep it stationary. At this time, the boss end face of the ejector pin is aligned with the No. 1 grinding wheel, and the control frame on the pusher frame is abutted against the lower part of the dial plate. Then, the servo slide continues to drive the pusher frame to move laterally. At this time, the spring body deforms, allowing the pusher frame to continue to move laterally when the I-beam frame is stationary. The continued lateral movement of the pusher frame drives the control frame to push the dial plate, causing the dial plate to move laterally and thus drive the pusher frame to move, pushing the slide to slide at the end of the sub-frame. This causes the rotating No. 1 grinding wheel to move backward to grind the boss end face of the ejector pin. During the process of pushing the ejector pin, the movement of the No. 1 grinding wheel to grind the end face can be controlled synchronously, without the need for additional personnel control, which effectively facilitates use.

[0031] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] like Figures 1-9The grinding machine shown includes a housing 1. A gear ring 4 is rotatably mounted on the front of the lower end of the housing 1. The gear ring 4 drives a second grinding wheel 36 to rotate circumferentially. A fixing frame 38 is fixedly mounted on the upper end of the gear ring 4. A second shaft 40 is rotatably mounted through the end of the fixing frame 38, and the fixing frame 38 supports the second shaft 40. The second grinding wheel 36 is coaxially fixedly mounted on the end of the second shaft 40. The grinding wheel 36 is arranged in a stepped shape, with the step height matching the height of the boss on the ejector pin 18. This ensures that the small-diameter end surface of the grinding wheel 36 contacts the outer surface of the boss on the ejector pin 18 for grinding. A support ring 35 is fixedly installed at the lower inner end of the gear ring 4. The support ring 35 matches the diameter of the ejector pin 18 and supports the ejector pin 18, allowing it to fully contact the grinding wheel 36. A flexible support ring is installed on the lower inner surface of the equipment housing 1 near the side of the gear ring 4. A slide 27 has a first shaft 31 rotatably mounted through one end of the slide 27. The slide 27 serves to support the first shaft 31. A first grinding wheel 34 is coaxially fixed to the end of the first shaft 31. The first grinding wheel 34 grinds the boss end face of the ejector pin 18. A clamping and pushing component is installed at the rear edge of the lower end face inside the equipment housing 1. The rotating gear ring 4 drives the self-rotating stepped second grinding wheel 36 to rotate circumferentially, utilizing the stepped... The large-diameter section of the stepped No. 2 grinding wheel 36 grinds the outer surface of the ejector pin 18, and the small-diameter section of the stepped No. 2 grinding wheel 36 grinds the outer surface of the boss of the ejector pin 18. After the outer surface is ground, the moving slide 27 drives the rotating No. 1 grinding wheel 34 to move backward and grind the end face of the boss of the ejector pin 18. In this way, the outer surface and end face of the ejector pin 18 are ground simultaneously. The process does not require equipment switching, which effectively improves the convenience of grinding.

[0033] A first motor 32 is fixedly installed on the other side of the end of the slide 27. The first motor 32 drives the first grinding wheel 34 to rotate. The output end of the first motor 32 is connected to the first shaft 31 through a pulley and a first belt 33. A second motor 37 is fixedly installed inside the fixed frame 38. The second motor 37 drives the second grinding wheel 36 to rotate. The output end of the second motor 37 is connected to the second shaft 40 through a pulley and a second belt 39. Both the first belt 33 and the second belt 39 serve as transmission belts.

[0034] A ring seat 41 is coaxially rotatably mounted on the side of the gear ring 4, and the ring seat 41 serves to support the gear ring 4. A main frame 3 is fixedly mounted on the front end of the ring seat 41, and the lower end of the main frame 3 is fixed to the equipment housing 1. A connecting shaft 43 is rotatably mounted through the side of the main frame 3, and a pinion 22 is coaxially fixedly mounted on one end of the connecting shaft 43. The connecting shaft 43 serves to transmit power. A gear plate 42 meshes with the front part of the pinion 22, and the gear plate 42 slides with the main frame 3. The front edge of the lower end of the equipment housing 1 is fixed through the ring seat 4. A reciprocating push cylinder 2 is installed, which drives the toothed plate 42 to move up and down reciprocally. The output end of the reciprocating push cylinder 2 is fixed to the toothed plate 42, and the other end of the connecting shaft 43 is coaxially fixed with a large gear 44. The large gear 44 meshes with the gear ring 4. The reciprocating push cylinder 2 drives the toothed plate 42 to move up and down reciprocally, which in turn drives the small gear 22 to rotate reciprocally. Thus, the large gear 44 drives the gear ring 4 to rotate reciprocally, so that the second grinding wheel 36 can rotate reciprocally to grind the ejector pin 18.

[0035] The clamping and pushing component includes a servo slide 6 fixedly installed at the rear edge of the lower end face inside the equipment housing 1. A pusher frame 19 is fixedly installed on the slide of the servo slide 6. An I-shaped frame 5 is elastically installed on the side of the pusher frame 19. The servo slide 6 drives the pusher frame 19 and the I-shaped frame 5 to move laterally. Prisms 23 are fixedly installed through both ends of the I-shaped frame 5. Two auxiliary sleeves 25 are symmetrically slidably installed on the outer surface of one of the prisms 23. Rod clamps 17 are fixedly installed at the opposite ends of the two auxiliary sleeves 25. The auxiliary sleeves 25 act as a clamp for the rod clamps 17. 7. To provide load-bearing capacity, two main sleeves 26 are symmetrically slidably mounted on the outer surface of another prism 23. The design of the protruding ridges on the prism 23 can prevent the main sleeves 26 and the secondary sleeves 25 from rotating. The opposite ends of the two main sleeves 26 are fixedly mounted with boss sleeves 16. The main sleeves 26 serve to support the boss sleeves 16. Rollers 13 are installed at the rear ends of the secondary sleeves 25 and the rear ends of the main sleeves 26. A magnet 15 is installed through the inner surface of the lower boss sleeve 16. The magnet 15 will attract the ejector pin 18 to prevent it from falling.

[0036] Two bending frames 11 are symmetrically fixedly installed on the lower inner surface of the equipment housing 1 behind the servo slide 6. The bending frames 11 allow the rod clamps 17 to move towards each other to clamp the ejector pins 18. Two trapezoidal frames 12 are symmetrically arranged on the sides of the bending frames 11. The trapezoidal frames 12 allow the boss clamps 16 to move towards each other to clamp the ejector pins 18. The trapezoidal frames 12 are fixed to the equipment housing 1. A positioning cap 14 is fixedly installed at the lower end of the I-shaped frame 5. A positioning support column 10 is arranged on the side of the positioning cap 14. The positioning support column 10 is fixed to the equipment housing 1. A sub-frame 9 is slidably installed on the outer surface of the slide 27. A lever 8 is slidably installed on the side of the sub-frame 9. A pusher frame 30 is rotatably installed at the end of the lever 8. The end of the pusher frame 30 is rotatably connected to the slide 27. A control frame 7 is fixedly installed at the front end of the pusher frame 19. After the outer surface of the ejector pin 18 is ground, the positioning... The cap 14 is pressed tightly against the positioning support column 10 to position the I-shaped frame 5 and keep it stationary. At this time, the boss end face of the ejector pin 18 is aligned with the first grinding wheel 34. At the same time, the control frame 7 on the pusher frame 19 is abutted against the lower part of the dial plate 8. Then, the servo slide 6 continues to drive the pusher frame 19 to move laterally. At this time, the spring body 21 deforms, allowing the pusher frame 19 to continue to move laterally when the I-shaped frame 5 is stationary. The pusher frame 19, which continues to move laterally, drives the control frame 7 to push the dial plate 8. The dial plate 8 moves laterally and drives the pusher frame 30 to move, so as to push the slide 27 to slide at the end of the sub-frame 9. This drives the rotating first grinding wheel 34 to move backward to grind the boss end face of the ejector pin 18. During the process of pushing the ejector pin 18, the movement of the first grinding wheel 34 to grind the end face can be controlled synchronously. No additional personnel control is required, which effectively facilitates the use.

[0037] A guide rod 28 is slidably mounted on the upper end of the sub-frame 9. The end of the guide rod 28 is fixed to the slide 27. A second return spring 29 is wound around the outside of the guide rod 28. The guide rod 28 prevents the second return spring 29 from bending. The two ends of the second return spring 29 are fixed to the slide 27 and the sub-frame 9 respectively. The second return spring 29 can return the slide 27 to its original position after it has been moved.

[0038] Two prisms 23 are wrapped with a first return spring 24 on their outer sides. The two ends of one first return spring 24 are fixed to the two auxiliary sleeves 25 respectively, and the two ends of the other first return spring 24 are fixed to the two main sleeves 26 respectively. The first return spring 24 can separate the two auxiliary sleeves 25 and the two main sleeves 26 to loosen the clamping of the ejector pin 18.

[0039] Two guide posts 20 are slidably mounted through the side of the pusher frame 19. The ends of the guide posts 20 are fixed to the I-shaped frame 5. The guide posts 20 guide the I-shaped frame 5. A spring body 21 is wound around the outside of the guide posts 20. The elastic force of the first reset spring 24 is greater than that of the spring body 21, so as to ensure that the pusher pin 18 can be clamped smoothly during the push. The two ends of the spring body 21 are fixed to the pusher frame 19 and the I-shaped frame 5 respectively. The deformation of the spring body 21 allows the pusher frame 19 to continue to move laterally when the I-shaped frame 5 is stationary.

[0040] A method for using a grinding machine for mold production and processing is also provided, including the following steps:

[0041] S1: Place the ejector pin 18 on the clamping pusher to clamp and push the ejector pin 18.

[0042] S2: At this time, the gear ring 4 rotates, which drives the self-rotating No. 2 grinding wheel 36 to rotate in a circle to grind the outer surface of the pushed ejector pin 18.

[0043] S3: After the outer surface of the ejector pin 18 is ground, the clamping pusher will push the slide 27 to move backward, which in turn will drive the rotating first grinding wheel 34 to move backward, so as to grind the boss end face of the ejector pin 18.

[0044] During grinding, the boss end of the ejector pin 18 is placed in the lower boss clamping sleeve 16. At this time, the magnet 15 will attract the ejector pin 18 to prevent it from falling off. Then, the servo slide 6 drives the pusher frame 19 and the I-shaped frame 5 to move laterally to advance the ejector pin 18. During this process, the roller 13 on the main sleeve 26 will roll along the inclined side of the trapezoidal frame 12, allowing the two boss clamping sleeves 16 to move towards each other to clamp the ejector pin 18 from the boss end. After clamping, the roller 13 on the main sleeve 26 will roll to the horizontal section of the trapezoidal frame 12, and then continue to advance, allowing the clamped ejector pin 18 to engage with the stepped No. 2 grinding wheel. The large-diameter section of wheel 36 contacts the outer surface of ejector pin 18 for grinding. When the outer surface of ejector pin 18 is ground and extends from the grinding area, roller 13 on the secondary sleeve 25 contacts the inclined side of bending frame 11 and rolls along its inclined side, allowing the two rod clamps 17 to move towards each other to clamp the end of ejector pin 18. After clamping, roller 13 on the secondary sleeve 25 rolls to the horizontal section of bending frame 11, while roller 13 on the main sleeve 26 rolls to the inclined side on the other side of trapezoidal frame 12. Then, it continues to advance. At this time, roller 13 on the main sleeve 26 is in contact with the first return spring 24. Under the action of elastic force, it rolls along the inclined side of the trapezoidal frame 12, allowing the two boss sleeves 16 to separate, loosening the clamp on the boss end of the ejector pin 18, exposing the boss end of the ejector pin 18. Then it continues to advance, allowing the boss of the ejector pin 18 to contact the small-diameter section surface of the stepped second grinding wheel 36, so as to grind the outer surface of the boss of the ejector pin 18. After the outer surface is ground, the positioning cap 14 is just pressed against the positioning support column 10 to position the I-shaped frame 5 and keep the I-shaped frame 5 stationary. At this time, the boss end face of the ejector pin 18 is just aligned with the first grinding wheel 34, and at the same time, the control frame 7 on the pusher frame 19 is just aligned with the dial plate. The lower parts of 8 abut against each other, and then the servo slide 6 continues to drive the pusher 19 to move laterally. At this time, the spring body 21 deforms, allowing the pusher 19 to continue to move laterally when the I-shaped frame 5 is stationary. The pusher 19, which continues to move laterally, drives the control frame 7 to push the dial plate 8, causing the dial plate 8 to move laterally and thus drive the pusher frame 30 to move, so as to push the slide 27 to slide at the end of the sub-frame 9, thereby driving the self-rotating first grinding wheel 34 to move backward to grind the boss end face of the ejector pin 18. Then the servo slide 6 moves in the opposite direction to drive the pusher 19 and the I-shaped frame 5 to reset. Then the ejector pin 18 can be removed to replace the next ejector pin 18 for grinding.
