Description

Technical Field

[0001] The invention relates to the technical field of mold processing clamping tables, and in particular to a clamping table for mold processing. Background Art

[0002] The clamping table for mold processing is an indispensable and important equipment in the mold processing process. It is mainly used to fix the mold blank to ensure that the mold blank can be stable and motionless during the processing, thereby improving the processing accuracy and efficiency. In addition, it mainly uses various clamping devices to firmly fix the mold blank on the clamping table for subsequent drilling, grinding and milling and other processing steps.

[0003] Most of the existing clamping tables for mold processing generally clamp and fix the mold by driving the clamp to move so as to facilitate the subsequent processing of the mold. In order to ensure the accuracy and stability of the mold during processing, it is necessary to increase the force of the clamp to clamp the mold to clamp the mold more firmly. However, after the mold is tightly clamped, the clamped part is prone to damage, which greatly affects the quality of the mold and is not conducive to the production of the mold. In addition, if the mold is clamped by an electromagnetic clamp, although damage to the mold can be avoided, the electromagnetic clamp only adsorbs and clamps the mold through an electromagnetic plate or electromagnetic disk after power is turned on. The clamping effect is limited and the mold cannot be clamped more firmly, thereby reducing the accuracy and stability of the mold during processing, thereby reducing the mold processing quality and poor practicality. Summary of the invention

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention can not only clamp and fix the cylindrical metal mold through the setting of the fixing mechanism, but also can perform multi-faceted grinding operations on the cylindrical metal mold in conjunction with the grinding liquid. After the cylindrical metal mold is initially clamped and fixed, the telescopic rod can drive the piston block to move to suck the air between the copper-clamped rubber ring and the cylindrical mold into the inside of the casing, thereby improving the adsorption force between the circular surface of the cylindrical mold and the copper-clamped rubber ring, which plays a role in reinforcement and fixation. Afterwards, the cylindrical metal mold is further reinforced and fixed by the electric field generated by the electromagnet in the fixing mechanism and the electrode plate after energization, thereby providing a stable clamping and fixing for the cylindrical mold, ensuring the accuracy and stability of the mold during processing. Moreover, since the reinforcement and fixing methods are all composed of adsorption fixation, rather than reinforcing and fixing the cylindrical mold by increasing the clamping force, the problem of easily causing damage to the clamped part of the mold when the mold is clamped and tightened can be avoided, thereby ensuring the production quality of the mold.

[0020] 2. The present invention, through the setting of the driving component in the fixing mechanism, can drive the electromagnet and the fixing clamp to clamp the two ends of the cylindrical mold, and can also drive the supporting wheel in the auxiliary fixing component to clamp the side of the cylindrical mold, thereby further improving the clamping stability. In addition, through the setting of the cleaning component on the supporting wheel, the side of the cylindrical mold can be cleaned in conjunction with the rotation of the supporting wheel when the cylindrical mold is rotated and polished.

[0021] 3. The present invention can effectively assist the fixing clamp to fix the cylindrical metal mold and prevent the cylindrical metal mold from slipping off the fixing clamp by setting a fixed rubber sheet, a rubber anti-skid sheet and an auxiliary anti-skid component on the fixing clamp. In addition, the setting of the rubber vertical sheet in the auxiliary anti-skid component can prevent the situation where the end of the rubber cylinder in contact with the cylindrical mold falls in the same direction when the fixing clamp rotates, thereby avoiding affecting the fixing and anti-skid effects of the rubber cylinder when the cylindrical mold is rotationally polished, thereby ensuring the stability of the cylindrical mold during rotational polishing.

[0022] 4. The present invention arranges the fur ring on the fixed ring so that when the cylindrical mold is rotated and polished, the fur ring on the fixed ring and the copper-clamped rubber ring are in contact and rotated to generate negative charges due to friction. Due to the existence of the electric field, the negative charges move to the contact surface between the copper-clamped rubber ring and the cylindrical mold, and the cylindrical mold surface in contact with it has positive charges, further enhancing the effect of the electrostatic adsorption force. In addition, by arranging the internal thin copper sheet of the copper-clamped rubber ring, the induced charge of the copper-clamped rubber ring can be increased while the electric field is uniformly enhanced, thereby strengthening electrostatic adsorption and promoting the stability of the fixed clamping of the cylindrical mold.

[0023] 5. The present invention uses the friction between the abrasive in the grinding liquid and the cylindrical mold, through the cooperation between the collecting mechanism and the electric field generated after the electrode plate is energized, so that the abrasive and the grinding chips generated by grinding are charged. Under the action of the electric field, they move to the two ends of the cylindrical mold and slide down, and finally fall into the collection box below through the through groove 1 on the table top, thereby completing the collection of the grinding chips generated during the grinding of the cylindrical mold, avoiding the situation where the grinding chips need to be stopped for cleaning after accumulating to a certain extent, thereby improving the efficiency of mold processing. In addition, the waste liquid formed after grinding and cleaning can fall into the collection box below through the through groove 2 in the middle of the table top, and finally be discharged through the outlet pipe connected to the bottom of the collection box, thereby avoiding the waste liquid from falling directly to the ground, thereby avoiding the staff from cleaning the waste liquid dripping on the ground, and reducing the labor intensity of the staff.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

Adjustment components are arranged in the two groups of columns 5, and the two groups of columns 5 are respectively connected to the two groups of casings 11 through the two groups of adjustment components. The adjustment components are used to enable the casing 11 to be lifted and rotated. The bottom ends of the two groups of columns 5 are in contact with the top of the table 1, and the two groups of columns 5 are installed with built-in power supplies. Electrode wires 6 are installed on the two groups of electrode plates 7, and the two groups of electrode plates 7 are respectively connected to the built-in power supplies in the two groups of columns 5 through the electrode wires 6.

[0034] Reference Figures 1 to 5The driving assembly includes a motor 18, a transverse moving component and a longitudinal moving component. The motor 18 is fixedly installed at the middle position of the bottom end of the second partition 4, and the output end of the motor 18 is fixedly connected to a rotating shaft 19. The rotating shaft 19 passes through the first partition 3 and the second partition 4 in sequence away from the motor 18, and a first gear 20 and a second gear 21 are fixedly installed on the outer side of the rotating shaft 19. The first gear 20 is located between the first partition 3 and the second partition 4, and the second gear 21 is located between the second partition 4 and the table 1. The transverse moving component includes two groups of transverse racks 22. The two groups of transverse racks 22 are arranged opposite to each other, and the two groups of transverse racks 22 are meshed with the first gear 20. The ends of the two groups of transverse racks 22 away from the first gear 20 pass through the first partition 3 and the second partition 4 in sequence, and are fixedly connected There are cylinders 25, two groups of cylinders 25 are symmetrically arranged in the through groove one, and are slidably connected to the cross bar 24 in the through groove one, springs 27 are fixedly installed at the openings of the two groups of cylinders 25, and the two groups of cylinders 25 are respectively connected to the two groups of insulating limit seats 28 through the springs 27, two groups of compression columns 26 are fixedly installed on the cross bar 24, the two groups of compression columns 26 are respectively slidably connected to the openings of the two groups of cylinders 25, and the two groups of compression columns 26 are respectively located in the two groups of springs 27, the longitudinal moving parts include two groups of longitudinal racks 23, the two groups of longitudinal racks 23 are arranged opposite to each other, and the two groups of longitudinal racks 23 are meshed with the second gear 21, and the ends of the two groups of longitudinal racks 23 away from the second gear 21 pass through the first partition 3 and the second partition 4 in sequence, and pass through the through groove two to be connected with the auxiliary fixing component.

[0035] Reference Figure 1 , Figure 3 and Figure 7The auxiliary fixing assembly includes two groups of positioning bases 29, and the two groups of positioning bases 29 are respectively connected to one end of the two groups of longitudinal racks 23 away from the second gear 21, and the tops of the two groups of positioning bases 29 are rotatably connected with two groups of rotating positioning rods 30, and the two groups of rotating positioning rods 30 are commonly inserted with a rotating rod 31. One of the groups of rotating positioning rods 30 on the two groups of positioning bases 29 is provided with a driving motor for driving the rotating rod 31 to rotate, and three groups of supporting wheels 32 are fixedly connected to the rotating rod 31. The rotating shaft 19 is driven to rotate by starting the motor 18, so that the first gear 20 on the second partition 4 and the second gear 21 on the first partition 3 rotate, and the transverse rack 22 and the longitudinal rack 23 are respectively on the first gear 20 The two gears 22 move inwards and move toward the middle of the table 1 at the same time. When the two sets of horizontal racks 22 move inwards, the cylinder 25 will be driven to move toward the direction of the spring 27 and apply a thrust to the spring 27. At this time, the elastic force of the spring 27 is greater than the thrust of the cylinder 25, and the spring 27 will not be compressed. Therefore, under the action of the cylinder 25, the insulating limit seat 28 can be pushed to move toward the middle through the spring 27. The insulating limit seat 28 is equipped with an electrode plate 7 connected to the column 5 through the electrode wire 6. The electrode plate 7 drives the housing 11 to move toward the middle until the copper rubber ring 13 and the electromagnet 12 on the same side and the fixing clamp 17 on the other side are completely in contact with the circular surface of the cylindrical mold, thereby completing the cylindrical mold at both ends. The clamping and clamping, at the same time, the longitudinal rack 23 moves inward to drive the positioning base 29 to move. When the supporting wheels 32 on both sides completely contact the side of the cylindrical mold, the positioning base 29 stops moving. One of the rotating positioning rods 30 on the two groups of positioning bases 29 is provided with a driving motor for driving the rotating rod 31 to rotate. The rotating rod 31 on the rotating positioning rod 30 can rotate, so that the supporting wheels 32 on the two groups of positioning bases 29 can be driven by the rotating rod 31 to rotate toward the cylindrical mold at the same time, thereby further playing a role of clamping and fixing, and finally completing the preliminary clamping and fixing of the cylindrical mold. If the electromagnet 12 and the fixing clamp 17 on the transverse rack 22 are clamped and fixed to the cylindrical mold, but the longitudinal If the supporting wheel 32 on the rack 23 is not in contact with the side of the cylindrical mold, the transverse rack 22 moves further inward. When the cylinder 25 pushes the insulating limit seat 28 by applying pressure to the spring 27, the electromagnet 12 and the copper rubber ring 13 on the insulating limit seat 28 cooperate with the fixing clamp 17 to clamp the cylindrical mold. When the insulating limit seat 28 is pushed, it will be in a stationary state. At this time, the cylinder 25 will continue to compress the spring 27 until the compression spring 27 is compressed. After the spring 27 is compressed, the compression column 26 enters the cylinder 25, so that the transverse rack 22 can move smoothly, and then the longitudinal rack 23 can smoothly drive the supporting wheel 32 to contact the side of the cylinder completely.If the supporting wheel 32 on the longitudinal rack 23 contacts the side of the cylindrical mold first, the supporting wheel 32 will push the rotating locking rod 30 above the locking base 29 to open to both sides until the electromagnet 12 and the fixing clamp 17 clamp the cylindrical mold. ;

[0036] Reference Figures 1 to 5 The adjusting assembly includes a lifting component, which is installed inside the column 5, and a rotating component is installed on the lifting component, which is located inside the column 5. The lifting component and the rotating component are both prior art, and their specific structural designs are not repeated here. A telescopic cylinder seat 8 is installed on the rotating component. The two groups of columns 5 are connected to the two groups of casings 11 through the telescopic cylinder seats 8 in the two groups of adjusting assemblies respectively. The output ends of the two groups of telescopic cylinder seats 8 are slidably connected with telescopic rods 9, one of which penetrates a group of electrode plates 7 and a group of outer walls of the casing 11 on the same side in sequence through the telescopic rod 9, and is fixedly connected with a piston block 10, the piston The block 10 is located inside the casing 11, and the outer wall of the piston block 10 is slidably connected to the inner wall of the casing 11. A through hole is penetrated at the center of the electromagnet 12. Another group of telescopic cylinder seats 8 penetrate another group of electrode plates 7 through the telescopic rod 9 and are fixedly connected to the outer wall of another group of casings 11. The telescopic cylinder seats 8 are driven up and down by the lifting components in the column 5, so that the electromagnets 12 and the fixing clamps 17 on both sides of the lateral side can be located at the center of the top and bottom surfaces of the cylindrical mold. Then, the cylindrical mold is initially clamped and fixed by the above-mentioned driving component. After clamping and fixing, the piston block 10 is driven toward the copper rubber ring 1 through the telescopic rod 9. 3 moves in the opposite direction of the movement, so that the air between the copper-clamped rubber ring 13 and the circular surface of the cylindrical mold is sucked into the housing 11 through the through hole on the electromagnet 12, thereby improving the adsorption force between the circular surface of the cylindrical mold and the copper-clamped rubber ring 13, making the circular surface of the cylindrical mold and the copper-clamped rubber ring 13 fit more closely, and then starting the electromagnet 12 to make the electromagnet 12 generate magnetism, thereby generating adsorption force on the cylindrical mold, and further strengthening the fixed clamping effect. After the cylindrical mold is completely clamped in the above manner, the built-in power supply in the two sets of columns 5 is used to make the two sets of columns 5 The electrode plates 7 are energized, and the left electrode plate 7 is the negative electrode, and the right electrode plate 7 is the positive electrode. An electric field of a fixed direction is formed between the two electrode plates 7, which promotes a more uniform arrangement of ions on the metal cylindrical mold, thereby making the adsorption and fixation of the electromagnet 12 more stable. From the above description, it can be seen that after the initial clamping of the cylindrical mold, the subsequent reinforcement and fixation of the cylindrical mold is composed of adsorption and fixation, rather than reinforcing and fixing the cylindrical mold by increasing the clamping force, thereby avoiding the problem of easily causing damage to the clamped part of the mold after the mold is tightly fixed.

[0037] Reference Figure 3 and Figure 6A fixed rubber sheet 175 is fixedly installed at the middle position of the side of the fixed clip 17 facing the copper rubber ring 13, and multiple groups of rubber anti-skid sheets 171 are evenly installed near the edge of the side of the fixed clip 17 facing the copper rubber ring 13. The fixed rubber sheet 175 and the multiple groups of rubber anti-skid sheets 171 are used to assist the fixed clip 17 to fix the cylindrical metal mold to prevent the cylindrical metal mold from slipping off the fixed clip 17. The side of the fixed clip 17 facing the copper rubber ring 13 is provided with an auxiliary anti-skid component to assist the fixed rubber sheet 175 and the rubber anti-skid sheet 171 to fix the cylindrical metal mold. The mold is fixed to further prevent the cylindrical metal mold from sliding off the fixing clamp 17. The auxiliary anti-skid component includes four groups of square grooves 172. The four groups of square grooves 172 are symmetrically opened on one side of the fixing clamp 17 in pairs, and the four groups of square grooves 172 are all located between the fixed rubber sheet 175 and the rubber anti-skid sheet 171. Four rows of rubber cylinders 173 and three groups of rubber vertical sheets 174 are fixedly installed in the four groups of square grooves 172. The three groups of rubber vertical sheets 174 are respectively located between the four rows of rubber cylinders 173. The rubber vertical sheets 174 and the rubber cylinders 173 both play a role in promoting anti-skid.

[0038] Reference Figure 1 , Figure 3 and Figure 5 A fixing ring 15 is sleeved on the outer side of a group of casings 11 near the copper-clamped rubber ring 13, and two groups of sliding support rods 14 are symmetrically installed on the outer side of the fixing ring 15, and the fixing ring 15 is slidably connected to the side wall of the electrode plate 7 through the two groups of sliding support rods 14. A fur ring 16 is fixedly installed on one end of the fixing ring 15 near the copper-clamped rubber ring 13, and the fur ring 16 and the copper-clamped rubber ring 13 are arranged in contact with each other. A thin copper sheet is installed inside the copper-clamped rubber ring 13. When it is necessary to grind the cylindrical mold, the rotating part in the column 5 is started to make the clamped cylindrical mold start to rotate. At this time, the fur ring 16 on the fixing ring 15 contacts and rotates with the copper-clamped rubber ring 13 to generate negative charges. Due to the existence of the electric field, the negative charges are transferred to the copper-clamped rubber ring 13 and the cylindrical The contact surface of the body mold moves, and the cylindrical mold surface in contact with it has a positive charge, which further enhances the effect of the electrostatic adsorption force. At the same time, since a thin copper sheet is installed inside the copper-clamped rubber ring 13, the induced charge of the copper-clamped rubber ring 13 can be increased while uniformly enhancing the electric field, strengthening electrostatic adsorption, and promoting the stability of the fixed clamping of the cylindrical mold. In addition, by setting the rubber vertical sheet 174 in the auxiliary anti-slip component, it can be avoided that when the fixed clamp 17 rotates, the four rows of rubber cylinders 173 and the ends in contact with the cylindrical metal mold fall in the same direction together, thereby avoiding affecting the fixing and anti-slip effects of the rubber cylinders 173, and then the cylindrical mold is polished by adding grinding fluid to the side of the rotating cylindrical mold.

[0039] Reference Figures 1 to 3 as well as Figure 7, the three groups of supporting wheels 32 are all provided with cleaning components for cleaning the surface of the cylindrical mold, the cleaning components include two groups of annular grooves 321, the two groups of annular grooves 321 are both opened on the outer wall of the supporting wheel 32, and the two groups of annular grooves 321 are both installed with bristles 322, a collecting mechanism is provided at the bottom end of the table 1 for collecting the grinding chips and waste liquid generated during grinding, the collecting mechanism includes a collecting box 2, the collecting box 2 is fixedly mounted at the bottom end of the table 1, and the collecting box 2 is connected to the outside through the through grooves 1 and 2 on the table 1, and the bottom end of the collecting box 2 is fixedly connected with a water outlet pipe 33, when the grinding operation is performed, the abrasive in the grinding liquid rubs against the cylindrical mold, so that the abrasive and the grinding chips generated by the grinding are attached with electric charges, and move to the two ends of the cylindrical mold under the action of the electric field and slide down, and finally fall into the collecting box 2 below through the through groove 1 on the table 1, thereby completing the collection of the grinding chips generated during the grinding of the cylindrical mold, and the grinding Timely collection of chips can avoid the situation where the machine needs to be shut down for cleaning after the chips accumulate to a certain level, thereby reducing the downtime during processing and improving the efficiency of mold processing. In addition, the collection of chips helps to reduce pollution to the working environment, thereby protecting the health of the staff while protecting the working environment. Since the support wheels 32 on the two sets of positioning bases 29 can rotate toward the cylindrical mold at the same time under the drive of the rotating rod 31, the bristles 322 on the support wheels 32 can clean the side of the cylindrical mold under the rotation of the support wheels 32. At the same time, the waste liquid formed after grinding and cleaning gathers under the cylindrical mold under the action of gravity, and falls into the collection box 2 below through the through groove 2 in the middle of the table 1, and is finally discharged through the outlet pipe 33 connected to the bottom of the collection box 2, thereby avoiding the waste liquid from falling directly to the ground, and then avoiding the staff from cleaning the waste liquid dripping on the ground, reducing the labor intensity of the staff.

[0040] In the present invention, the cylindrical metal mold to be polished is placed horizontally in the middle of the table 1 supported by four column legs 34, and the lifting component in the column 5 drives the telescopic cylinder seat 8 to move up and down, so that the clamps on both sides of the lateral side can be located at the center of the top and bottom surfaces of the cylindrical mold. The motor 18 is started to drive the rotating shaft 19 to rotate, so that the first gear 20 on the second partition 4 and the second gear 21 on the first partition 3 rotate, and the horizontal rack 22 and the longitudinal rack 23 move toward the middle at the same time driven by the first gear 20 and the second gear 21 respectively.

[0041] The transverse rack 22 moves inward, driving the cylinder 25 to move toward the spring 27 and applying a thrust to the spring 27. At this time, the elastic force of the spring 27 is greater than the thrust of the cylinder 25, and the spring 27 will not be compressed. Therefore, under the action of the cylinder 25, the insulating limit seat 28 can be pushed to move toward the middle through the spring 27. The insulating limit seat 28 is equipped with an electrode plate 7 connected to the column 5 through the electrode wire 6. The electrode plate 7 drives the housing 11 to move toward the middle until the copper rubber ring 13 and the electromagnet 12 on the same side and the fixed clamp 17 on the other side are completely in contact with the circular surface of the cylindrical mold, thereby completing the clamping of the two ends of the cylindrical mold. The outer ring of the fixed clamp 17 is provided with a rubber anti-slip sheet 171, and the center of the fixed clamp 17 is provided with a fixed The four rows of rubber cylinders 173 slightly higher than the plane of the fixed clamp 17 inside the four square grooves 172 of the inner circle play a further anti-skid role. There are three groups of rubber vertical sheets 174 in the middle of each row of rubber cylinders 173. The rubber vertical sheets 174 promote the anti-skid effect while preventing the rubber cylinders 173 from falling in the same direction during rotation, affecting the fixation and anti-skid effects. The longitudinal rack 23 moves inward to drive the positioning base 29 to move. When the support wheels 32 on both sides completely contact the side of the cylindrical mold, the positioning base 29 stops moving, and the support wheels 32 on both sides rotate simultaneously in the direction of the cylindrical mold driven by the rotating rod 31, thereby further playing a role of clamping and fixing, and finally completing the preliminary clamping and fixing of the cylindrical mold.

[0042] If the electromagnet 12 and the fixing clamp 17 on the transverse rack 22 are clamped and fixed to the cylindrical mold, but the supporting wheel 32 on the longitudinal rack 23 is not in contact with the side of the cylindrical mold, the transverse rack 22 moves further inward. When the cylinder 25 pushes the insulating limit seat 28 by applying pressure to the spring 27, the electromagnet 12 and the copper rubber ring 13 on the insulating limit seat 28 cooperate with the fixing clamp 17 to clamp the cylindrical mold. The insulating limit seat 28 will be in a stationary state when it is pushed. At this time, the cylinder 2 5 will continue to compress the spring 27 until the compression spring 27 is compressed. After the spring 27 is compressed, the compression column 26 enters the cylinder 25, so that the transverse rack 22 can move smoothly, and then the longitudinal rack 23 can smoothly drive the supporting wheel 32 to fully contact the side of the cylinder; if the supporting wheel 32 on the longitudinal rack 23 contacts the side of the cylindrical mold first, the supporting wheel 32 will push the rotating locking rod 30 above the locking base 29 to open to both sides until the electromagnet 12 and the fixing clamp 17 clamp the cylindrical mold.

[0043] After the initial clamping and fixing of the cylindrical mold is completed, the piston block 10 is driven by the telescopic rod 9 to move in the opposite direction of the copper rubber ring 13, so that the air between the copper rubber ring 13 and the circular surface of the cylindrical mold is sucked into the casing 11 through the through hole on the electromagnet 12, thereby improving the adsorption force between the circular surface of the cylindrical mold and the copper rubber ring 13, making the fit between the circular surface of the cylindrical mold and the copper rubber ring 13 tighter, and then starting the electromagnet 12 to make the electromagnet 12 magnetic, thereby generating adsorption force on the cylindrical mold, thereby further strengthening the fixed clamping effect, after the cylindrical mold is completely clamped in the above manner, the two sets of electrode plates 7 are energized, at this time the left electrode plate 7 is the negative electrode, the right electrode plate 7 is the positive electrode, and the two electrodes are An electric field of a fixed direction is formed between the plates 7, which promotes a more uniform arrangement of ions on the metal cylindrical mold, makes the adsorption and fixation of the electromagnet 12 more stable, starts the rotating part in the column 5, and causes the clamped cylindrical mold to start rotating. After the sliding support rod 14 follows the vertical displacement of the lifting part of the column 5 to a fixed position, the fur ring 16 on the fixing ring 15 contacts and rotates with the copper-clamped rubber ring 13 to generate negative charges due to friction. Due to the existence of the electric field, the negative charges move toward the contact surface between the copper-clamped rubber ring 13 and the cylindrical mold, and the cylindrical mold surface in contact with it carries a positive charge, further enhancing the effect of the electrostatic adsorption force. At the same time, a thin copper sheet is installed inside the copper-clamped rubber ring 13, which increases the amount of induced charge while uniformly enhancing the electric field, strengthens electrostatic adsorption, and promotes the stability of the fixed clamping of the cylindrical mold.

[0044] Then, grinding liquid is added to the side of the cylindrical mold to grind the cylindrical mold. The abrasive in the grinding liquid rubs against the cylindrical mold, so that the abrasive and the grinding chips generated by grinding are charged, and move and slide toward the two ends of the cylindrical mold under the action of the electric field, and finally fall into the collection box 2 below through the through groove 1 on the table 1, thereby completing the collection of the grinding chips generated during the grinding of the cylindrical mold. The timely collection of grinding chips can avoid the situation where the machine needs to be stopped for cleaning after the grinding chips accumulate to a certain extent, thereby reducing the downtime during the processing and improving the efficiency of mold processing. In addition, the collection of grinding chips helps to reduce pollution to the working environment, thereby protecting The working environment is improved while the health of the staff is protected. Since the support wheels 32 on the two sets of positioning bases 29 can rotate toward the cylindrical mold at the same time under the drive of the rotating rod 31, the bristles 322 on the support wheels 32 can clean the side of the cylindrical mold under the rotation of the support wheels 32. At the same time, the waste liquid formed after grinding and cleaning gathers under the cylindrical mold under the action of gravity, and falls into the collection box 2 below through the through groove 2 in the middle of the table 1, and is finally discharged through the outlet pipe 33 connected to the bottom of the collection box 2, thereby preventing the waste liquid from falling directly to the ground, and then avoiding the staff from cleaning the waste liquid dripping on the ground, reducing the labor intensity of the staff.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
