A super large integrated die casting mold processing equipment

Abstract

The present invention relates to the field of mold processing technology, specifically to a super-large integrated die-casting mold processing equipment, including a processing stand, and a processing component is arranged on the top of the processing stand. If the bottom of the die-casting mold is uneven and protruding, the protruding part presses the grinding sandpaper downward, and the grinding sandpaper presses the sandpaper frame downward, and the corrugated copper tube is compressed downward by the sandpaper frame, and the internal pressure increases. The air pressure sensor senses that the internal pressure of the corrugated copper tube increases, and the electromagnet is started. The electromagnet generates a magnetic field that is mutually attracted with the I-shaped permanent magnetic ring, so that the I-shaped permanent magnetic ring moves along the driving shaft toward the direction of the electromagnet. The movement of the I-shaped permanent magnetic ring drives the two key blocks to move along the two key slots together, and the movement of the two key blocks drives the feed gear to move along the outer wall of the driving shaft. The feed gear is dislocated with the feed rack through the movement, thereby releasing the meshing effect, and the U-shaped processing table stops moving to the right, so that the grinding sandpaper focuses on grinding the protruding part of the bottom of the die-casting mold.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, if the bottom of the die-casting mold is uneven and has protrusions, the protruding part of the bottom of the die-casting mold will squeeze the grinding sandpaper downward, and the sandpaper rack will be squeezed downward by the grinding sandpaper, and the corrugated copper tube will be compressed downward by the sandpaper rack, and the internal pressure will increase. The air pressure sensor senses the increase in the internal pressure of the corrugated copper tube, and starts the electromagnet. The electromagnet generates a magnetic field that is mutually attracted with the I-shaped permanent magnetic ring, so that the I-shaped permanent magnetic ring moves along the driving shaft toward the direction of the electromagnet. The movement of the I-shaped permanent magnetic ring drives the two key blocks to move along the two key slots together, and the movement of the two key blocks drives the feed gear to move along the outer wall of the driving shaft. The feed gear is misaligned with the feed rack through movement, thereby releasing the meshing effect, and the U-shaped processing table stops moving to the right, so that the grinding sandpaper focuses on grinding the protruding part of the bottom of the die-casting mold.

[0020] 2. In the present invention, in the process of moving the I-shaped permanent magnetic ring by adsorbing the electromagnet, the shift block is driven to move together through the switching action of the I-shaped permanent magnetic ring and the switching groove. The movement of the shift block is affected by the sliding connection effect of the guide hole and the guide rod, so that the movement of the shift block is more stable and smooth. The movement of the shift block drives multiple rollers at its bottom to roll along the surface of the inclined surface. The wedge force generated by the rolling of the rollers along the surface of the inclined surface pushes the brake block to move downward along the inner wall of the telescopic square groove. The downward movement of the brake block drives the spring seat to move, causing the second return spring to compress and accumulate force. The brake block moves downward, causing its bottom to contact the top of the brake strip, thereby generating a braking effect, ensuring that after the feed gear and the feed rack are disengaged, the U-shaped processing table will not move, thereby accurately grinding the protruding part of the bottom of the die-casting mold.

[0021] 3. In the present invention, the rotation of the servo motor also drives the driving pulley to rotate together. The rotation of the driving pulley drives the two driven pulleys together with the two cleaning shafts to rotate through the power belt. The rotation of the two cleaning shafts drives the two cleaning brushes to rotate, so as to wipe the top of the brake strip and remove the grinding chips that fall on the top of the brake strip during the grinding process, thereby ensuring that the bottom of the brake block can contact the top of the brake strip to generate sufficient braking force effect.

The drive shaft 208 passes through the back of the U-shaped processing table 201, and the drive shaft 208 is rotatably connected to the back of the U-shaped processing table 201 through a bearing. A feed gear 2012 is slidably installed on the rear part of the outer wall of the drive shaft 208, wherein a feed rack 2013 is fixedly installed on the top of a guide rail 400 located at the rear, and the feed gear 2012 is located at the top of the feed rack 2013, and the feed gear 2012 is meshed with the feed rack 2013. A driving bevel gear 2014 is fixedly installed on the front part of the outer wall of the drive shaft 208, and a driven bevel gear 2015 is fixedly installed on the bottom of the processing vertical shaft 202, and the driving bevel gear 2014 is meshed with the driven bevel gear 2015;

[0034] Two key slots 2081 are provided at the rear of the outer wall of the driving shaft 208, and the two key slots 2081 are symmetrically distributed about the center of the driving shaft 208. Key blocks 209 are slidably installed inside the two key slots 2081. The inner wall of the feed gear 2012 is fixedly connected to the rear ends of the outer walls of the two key blocks 209. An I-shaped permanent magnet ring 2010 is slidably installed on the outer wall of the driving shaft 208, and the inner wall of the I-shaped permanent magnet ring 2010 is fixedly connected to the front ends of the outer walls of the two key blocks 209. An electromagnet 2011 is fixedly installed on the rear wall of the U-shaped processing table 201, and the electromagnet 2011 is located on the periphery of the driving shaft 208, and the electromagnet 2011 is located on the back of the I-shaped permanent magnet ring 2010.

[0035] A positioning ring 2016 is fixedly installed on the outer wall of the driving shaft 208. The positioning ring 2016 is located in front of the I-shaped permanent magnet ring 2010. A first return spring 2017 is fixedly installed between the positioning ring 2016 and the I-shaped permanent magnet ring 2010.

[0036] Specifically, the die-casting mold is positioned at the top of the device by a robot arm or a workpiece fixing fixture, and the height of the die-casting mold is adjusted to ensure that the bottom of the die-casting mold fits the top of the processing component 200 and that the bottom of the die-casting mold does not apply pressure to the top of the processing component 200. The output shaft of the servo motor 207 drives the drive shaft 208 to rotate, and the driving bevel gear 2014 is driven to rotate by the rotation of the drive shaft 208, and the driven bevel gear 2015 is driven to rotate by the rotation of the driving bevel gear 2014. The processing vertical axis 202 is driven to rotate together with the turntable 203 by the rotation of the turntable 203. The corrugated copper tube 204 and the sandpaper holder 205 are driven to rotate by the rotation of the turntable 203. It should be additionally explained that before use, It is necessary to install sandpaper on the top of the sandpaper holder 205. In the device, the sandpaper holder 205 and the sandpaper are fixed by Velcro bonding to facilitate the replacement of the sandpaper. The rotation of the sandpaper holder 205 further drives the sandpaper fixed on the top to rotate, thereby grinding the bottom of the die-casting mold. At the same time, the output shaft of the servo motor 207 drives the drive shaft 208 to rotate. Under the torque limiting action of the key slot 2081 and the key block 209, the feed gear 2012 is further driven to rotate. Through the meshing action of the feed gear 2012 and the feed rack 2013, the feed gear 2012 rolls along the top of the feed rack 2013 during rotation, and further drives the U-shaped processing under the connection action of the drive shaft 208. The table 201 moves to the right along the front and rear guide rails 400, and the bottom of the die-casting mold is linearly polished to the right. If the bottom of the die-casting mold is uneven and protruding, the protruding part of the bottom of the die-casting mold will squeeze the sandpaper downward, and the sandpaper holder 205 is squeezed downward by the sandpaper, and the corrugated copper tube 204 is compressed downward by the sandpaper holder 205. The corrugated copper tube 204 is compressed, causing the internal pressure to increase. When the air pressure sensor 206 senses that the internal pressure of the corrugated copper tube 204 increases, the air pressure sensor 206 starts the electromagnet 2011, and the electromagnet 2011 generates a magnetic field that attracts the I-shaped permanent magnet ring 2010, so that the I-shaped permanent magnet ring 2010 moves along the drive shaft 208 toward the direction of the electromagnet 2011. This process causes the first reset The spring 2017 is stretched and stores force, and the two key blocks 209 are driven to move along the two key slots 2081 through the movement of the I-shaped permanent magnet ring 2010, and the feed gear 2012 is driven to move along the outer wall of the drive shaft 208 through the movement of the two key blocks 209. The feed gear 2012 is misaligned with the feed rack 2013 through movement, thereby releasing the meshing effect, and the U-shaped processing table 201 stops moving to the right, so that the grinding sandpaper focuses on grinding the protruding part of the bottom of the die-casting mold. With the continuous grinding of the protruding part of the die-casting mold, the protruding part of the bottom of the die-casting mold is gradually polished and smoothed, so the downward extrusion effect on the corrugated copper tube 204 is gradually weakened, and the corrugated copper tube 204 gradually rebounds under the action of the internal pressure until the corrugated copper tube 204 rebounds completely.This means that the protruding part at the bottom of the die-casting mold is completely polished and smooth, and the corrugated copper tube 204 completely rebounds and the internal pressure returns to the initial state. After the air pressure sensor 206 senses that the internal pressure of the corrugated copper tube 204 has recovered, the air pressure sensor 206 immediately controls the electromagnet 2011 to cut off the power, and the magnetic field generated by the electromagnet 2011 disappears. The I-shaped permanent magnet ring 2010 is reset by the rebound force of the first reset spring 2017. The reset of the I-shaped permanent magnet ring 2010 further drives the feed gear 212 to reset through the two key blocks 209. The feed gear 212 is reset and meshes with the feed rack 213 again. The U-shaped processing table 201 continues to move to the right. If there are still uneven protruding parts, continue the above process of polishing to make the bottom of the die-casting mold flat.

[0037] Embodiment 2: A positioning component 300 is provided inside the processing component 200, and the positioning component 300 includes an offset block 301, and a transfer groove 302 is provided through the upper front part of the offset block 301, and the offset block 301 is rotatably installed on the periphery of the I-shaped permanent magnet ring 2010 through the transfer groove 302. The positioning component 300 also includes a limit block 303 fixedly installed on the lower rear wall of the U-shaped processing table 201, and a telescopic square groove 304 is provided through the top of the limit block 303 downward, and a brake block 305 is slidably installed inside the telescopic square groove 304, and a slope 306 is provided on the top of the brake block 305, and the slope 306 is located at the bottom of the offset block 301, wherein a brake strip 3013 is fixedly installed on the front of a guide rail 400 located at the rear, and the brake strip 3013 is located at the bottom of the brake block 305;

[0038] The bottom of the offset block 301 is provided with a plurality of placement grooves 309 distributed left and right, and rollers 3010 are rotatably installed inside the placement grooves 309, and the bottom of the rollers 3010 abuts against the surface of the inclined surface 306, and a spring seat 307 is fixedly installed on the back of the brake block 305, and the spring seat 307 is located at the top of the limit block 303, and a second return spring 308 is fixedly installed between the bottom of the spring seat 307 and the top of the limit block 303, and a guide hole 3011 is opened through the front of the offset block 301, and a guide rod 3012 is fixedly installed on the rear wall of the U-shaped processing table 201, and the inner wall of the guide hole 3011 is slidably connected to the outer wall of the guide rod 3012;

[0039] Specifically, in this embodiment, when the electromagnet 2011 absorbs the I-shaped permanent magnet ring 2010 and moves, the shift block 301 is driven to move together through the switching effect between the I-shaped permanent magnet ring 2010 and the switching groove 302. The movement of the shift block 301 is affected by the sliding connection effect between the guide hole 3011 and the guide rod 3012, so that the movement of the shift block 301 is more stable and smooth. The movement of the shift block 301 drives the multiple rollers 3010 at the bottom thereof to roll along the surface of the inclined surface 306. The rollers 3010 roll along the surface of the inclined surface 306. The wedge force generated by the rolling of the surface pushes the brake block 305 to move downward along the inner wall of the telescopic square groove 304. The downward movement of the brake block 305 drives the spring seat 307 to move, causing the second return spring 308 to be compressed and accumulate force. The brake block 305 moves downward, causing its bottom to contact the top of the brake strip 3013, thereby producing a braking effect, ensuring that the U-shaped processing table 201 will not move after the feed gear 2012 and the feed rack 2013 are disengaged, thereby accurately grinding the protruding parts of the bottom of the die-casting mold.

[0040] Embodiment 3: Two cleaning shafts 3014 are rotatably installed between the front wall and the rear wall of the U-shaped processing table 201, and are distributed on the left and right. Cleaning brushes 3015 are fixedly installed on the rear of the outer wall of the two cleaning shafts 3014, and the cleaning brushes 3015 are located on the top of the brake strip 3013. A driven pulley 3016 is fixedly installed in the middle of the outer wall of the two cleaning shafts 3014, and a driving pulley 3017 is fixedly installed in the middle of the outer wall of the driving shaft 208. The outer periphery of the driving pulley 3017 and the two driven pulleys 3016 is commonly sleeved with a power belt 3018;

[0041] Specifically, the present embodiment drives the driving pulley 3017 to rotate through the rotation of the servo motor 207. The driving pulley 3017 drives the two driven pulleys 3016 and the two cleaning shafts 3014 to rotate through the power belt 3018. The two cleaning brushes 3015 are driven to rotate through the rotation of the two cleaning shafts 3014 to wipe the top of the brake strip 3013, and remove the grinding chips that fall on the top of the brake strip 3013 during the grinding process, to ensure that the bottom of the brake block 305 can contact the top of the brake strip 3013 to generate sufficient braking force.

[0042] Embodiment 4: An adjustment seat 500 is fixedly installed at both ends of the two guide rails 400. There are two adjustment seats 500. Two longitudinal polished rods 501 distributed left and right are fixedly installed on the top of the processing platform 100. The adjustment seat 500 is slidably installed on the periphery of the longitudinal polished rod 501. An internal thread seat 502 is fixedly installed at the bottom of one of the guide rails 400 located at the front. An adjustment screw 503 is screwed to the internal thread of the internal thread seat 502. The adjustment screw 503 is rotatably installed on the top of the processing platform 100 through a bearing;

[0043] Specifically, the present embodiment generates a spiral pushing effect by rotating the adjusting screw 503 and the internal threaded seat 502, so that the front and rear guide rails 400 and the left and right adjustment seats 500 move forward or backward along the left and right longitudinal light rods 501, further driving the processing component 200 and the positioning component 300 to move together. By adjusting the front and rear position of the processing component 200, the front and rear position of the bottom of the die-casting mold can be adjusted, so as to cooperate with the left and right movement of the processing component 200 and grind the bottom of the die-casting mold as a whole.

[0044] In the present solution, when a super-large integrated die-casting mold processing device is working, the die-casting mold is positioned at the top of the device by a robot arm or a workpiece fixing fixture, and the height of the die-casting mold is adjusted to ensure that the bottom of the die-casting mold fits the top of the processing component 200 and ensure that the bottom of the die-casting mold does not exert pressure on the top of the processing component 200;

[0045] The output shaft of the servo motor 207 drives the driving shaft 208 to rotate, and the driving shaft 208 drives the active bevel gear 2014 to rotate, and the active bevel gear 2014 drives the driven bevel gear 2015 to rotate, and the driven bevel gear 2015 drives the processing vertical shaft 202 to rotate together with the turntable 203, and the corrugated copper tube 204 drives the sandpaper holder 205 to rotate together with the turntable 203. It should be noted that before use, sandpaper needs to be installed on the top of the sandpaper holder 205. In the device, the sandpaper holder 205 and the sandpaper are fixed by Velcro bonding, so that the sandpaper can be replaced easily. 05 The rotation further drives the grinding sandpaper fixed on the top to rotate, thereby grinding the bottom of the die-casting mold. At the same time, the output shaft of the servo motor 207 drives the driving shaft 208 to rotate, and the feed gear 2012 is further driven to rotate through the torque limiting action of the keyway 2081 and the key block 209. The feed gear 2012 is meshed with the feed rack 2013, so that the feed gear 2012 rolls along the top of the feed rack 2013 during rotation, and further driven by the connection action of the drive shaft 208 to move the U-shaped processing table 201 to the right along the front and rear guide rails 400, and the bottom of the die-casting mold is linearly ground to the right;

[0046] If the bottom of the die-casting mold is uneven and has protrusions, the protruding part of the bottom of the die-casting mold will squeeze the sandpaper downward, and the sandpaper will squeeze the sandpaper rack 205 downward, and the corrugated copper tube 204 will be compressed downward by the sandpaper rack 205. The corrugated copper tube 204 is compressed, causing the internal pressure to increase. When the air pressure sensor 206 senses that the internal pressure of the corrugated copper tube 204 increases, the air pressure sensor 206 starts the electromagnet 2011, and the electromagnet 2011 generates a magnetic field that attracts the I-shaped permanent magnetic ring 2010, so that the I-shaped permanent magnetic ring 2010 moves along the drive shaft 208 in the direction of the electromagnet 2011, and this process causes the first return spring 2017 to be stretched and stored. The two key blocks 209 are driven to move along the two key slots 2081 through the movement of the I-shaped permanent magnet ring 2010, and the feed gear 2012 is driven to move along the outer wall of the drive shaft 208 through the movement of the two key blocks 209. The feed gear 2012 is dislocated with the feed rack 2013 through movement, thereby releasing the meshing effect, and the U-shaped processing table 201 stops moving to the right, so that the sandpaper is pressed against the die-casting mold. The protruding part at the bottom is polished emphatically. With the continuous polishing of the protruding part of the die-casting mold, the protruding part at the bottom of the die-casting mold is gradually polished and smoothed. Therefore, the downward extrusion effect on the corrugated copper tube 204 is gradually weakened, and the corrugated copper tube 204 gradually rebounds under the action of the internal pressure until the corrugated copper tube 204 rebounds completely. This indicates that the protruding part at the bottom of the die-casting mold is completely polished and smoothed, and the internal pressure of the corrugated copper tube 204 is completely rebounded to restore to the initial state. After the air pressure sensor 206 senses that the internal pressure of the corrugated copper tube 204 has recovered, the air pressure The sensor 206 immediately controls the electromagnet 2011 to be powered off, and the magnetic field generated by the electromagnet 2011 disappears. The I-shaped permanent magnet ring 2010 is reset by the resilience of the first reset spring 2017. The I-shaped permanent magnet ring 2010 is reset and further drives the feed gear 212 to reset through the two key blocks 209. The feed gear 2012 is reset and meshes with the feed rack 213 again. The U-shaped processing table 201 continues to move to the right. If there are still uneven protruding parts, the above process of grinding is continued to make the bottom of the die-casting mold flat.

[0047] When the electromagnet 2011 absorbs the I-shaped permanent magnet ring 2010 and moves, the shift block 301 is driven to move together through the switching effect of the I-shaped permanent magnet ring 2010 and the switching groove 302. The movement of the shift block 301 is affected by the sliding connection effect of the guide hole 3011 and the guide rod 3012, so that the movement of the shift block 301 is more stable and smooth. The movement of the shift block 301 drives multiple rollers 3010 at its bottom to roll along the surface of the inclined surface 306. The wedge force generated by the rolling of the rollers 3010 along the surface of the inclined surface 306 pushes the brake block 305 to move downward along the inner wall of the telescopic square groove 304. The downward movement of the brake block 305 drives the spring seat 307 to move, causing the second return spring 308 to be compressed and stored. The brake block 305 moves downward, causing its bottom to contact the top of the brake strip 3013, thereby generating The braking effect ensures that the U-shaped processing table 201 will not move after the feed gear 2012 and the feed rack 2013 are disengaged, thereby accurately grinding the protruding parts at the bottom of the die-casting mold. At the same time, while the servo motor 207 is driven to rotate by the output shaft of the servo motor 207, the rotation of the servo motor 207 also drives the active pulley 3017 to rotate together. The rotation of the active pulley 3017 drives the two driven pulleys 3016 and the two cleaning shafts 3014 to rotate through the power belt 3018. The rotation of the two cleaning shafts 3014 drives the two cleaning brushes 3015 to rotate, wipe the top of the brake strip 3013, and remove the grinding chips that fall on the top of the brake strip 3013 during the grinding process, to ensure that the bottom of the brake block 305 can contact the top of the brake strip 3013 to produce sufficient braking force effect.

[0048] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
