Description

Technical Field

[0001] The utility model relates to the field of mold processing, in particular to a grinding mechanism for mold processing. Background Art

[0002] After searching the patent document with the announcement number CN220051346U, the motor drives the chassis and the friction disk to frictionally grind the plate processed by the mold, and the debris at the grinding site is discharged through the discharge groove. At the same time, the centrifugal force of the friction disk causes the counterweight column to pull the double racks to translate outward to drive the linkage gear rod to rotate, and the linkage gear rod drives the linkage gear and the spring rod to translate downward, and the solid lubricant on the storage seat is pressed against the surface of the mold product by the spring rod for lubrication;

[0003] The patent document states that during the process of the storage seat pushing the solid lubricant downward, the centrifugal force of the entire friction disk is always present, and the solid lubricant is always applied to the workpiece being ground through the above-mentioned structural transmission. As the grinding time increases, a large amount of solid lubricant is always present between the friction disk and the grinding surface of the workpiece during the entire grinding process. Therefore, this may reduce the friction between the friction disk and the grinding surface of the workpiece, thereby reducing the grinding force of the friction disk on the grinding surface of the workpiece, affecting the overall grinding quality.

[0032] In this embodiment, the moving mechanism 3 includes two lifting frames 32, two hydraulic cylinders 31 are provided on both sides of the two lifting frames 32, two moving screws 34 are rotatably connected between the two lifting frames 32, a moving motor 33 for driving the moving screw 34 located on the front side to rotate is fixed on the lifting frames 32, and a moving seat 35 is threadedly connected to the two moving screws 34, a grinding motor 4 is provided on the top of the moving seat 35, a protective frame 7 is provided at the bottom of the moving seat 35, and a grinding wheel 6 for grinding the workpiece is provided on the lower side of the protective frame 7. The telescopic part of the hydraulic cylinder 31 is used to push the lifting frame 32 to drive the moving screw 34 to move downward, and the moving screw 34 is driven to rotate by the moving motor 33, thereby driving the moving seat 35 to move on both sides, and then adjusting the grinding position of the entire grinding wheel 6.

[0033] In this embodiment, the oil injection mechanism 5 includes a lubrication box 51, which is located on one side of the mobile motor 33. A liquid dispensing tube rack 54 for evenly directing the lubricant to the grinding wheel 6 is provided on the protective frame 7. A push tube 52 for pushing the lubricant into the liquid dispensing tube rack 54 is connected to the inner side of the liquid dispensing tube rack 54. A piston rod 55 is provided inside the push tube 52. A ring is rotatably connected to one end of the piston rod 55 close to the protective frame 7. A drive shaft 56 for transmitting the power of the grinding motor 4 to the grinding wheel 6 is provided inside the protective frame 7. The drive shaft 56 is provided inside the driving frame 7. A push block 57 is fixed at the collar position, the lubrication box 51 is connected to the push cylinder 52 through a liquid guide tube 53, springs are arranged on the front and rear sides of the piston rod 55 to reset it after moving, a notch is provided on the protective frame 7 to facilitate the insertion of the collar, a first one-way valve is arranged on the liquid guide tube 53 to prevent the lubricant in the push cylinder 52 from flowing back, and a second one-way valve is arranged at the connection position between the push cylinder 52 and the liquid distribution tube frame 54 to prevent the lubricant from flowing back into the push cylinder 52, the grinding motor 4 is used to drive the grinding wheel 6 to rotate through the driving shaft 56, and the grinding wheel 6 rotates with the grinding motor 4. That is, the grinding wheel 6 is used to grind the workpiece, and at the same time, the driving shaft 56 drives the push block 57 to rotate to push the piston rod 55 extending into the inner side of the protective frame 7. In this process, the piston rod 55 moves away from the driving shaft 56 to push the lubricant, and at the same time, the sleeve on the piston rod 55 is used to reduce the friction force when the push block 57 pushes the piston rod 55. In the process of the piston rod 55 pushing the lubricant, the first one-way valve on the liquid guide tube 53 is closed, and the second one-way valve is opened and the push block 57 is pushed when the piston rod 55 moves. The lubricant in the delivery tube 52 is pushed into the dispensing tube rack 54, and the lubricant is evenly dispersed to the outer side of the grinding wheel 6 through the dispensing tube rack 54; in addition, after the piston rod 55 finishes pushing the lubricant, the springs on the front and rear sides of the piston rod 55 are used to push the piston rod 55 to move in the opposite direction. During this process, the piston rod 55 draws the lubricant in the lubrication box 51 into the delivery tube 52 through the liquid guide tube 53. At this time, the first one-way valve is turned on, and the second one-way valve is closed. At the same time, the sleeve of the piston rod 55 is moved into the groove of the protective frame 7.

[0034] Working principle: When in use, lubricant is fed into the lubrication box 51, and the workpiece to be ground is placed on the three support rollers 12, and then the telescopic parts of the four clamping cylinders 24 are extended at the same time and push the clamping frame 21 to move along the L-shaped groove, and the clamping rollers 23 on the clamping frame 21 are used to roll and support the two sides of the workpiece, and when the workpiece is ground, the clamping rollers 23 at the lower end are driven to rotate by the rotating motor 22, and the workpiece is driven to move slowly to the rear side by the rotation of the four clamping rollers 23;

[0035] The telescopic parts of the four hydraulic cylinders 31 simultaneously push the lifting frame 32 to move downward. When the grinding wheel 6 is attached to the workpiece to be ground, the hydraulic cylinder 31 stops extending, and at the same time, the rotating part of the moving motor 33 drives the moving screw 34 to rotate forward. When the moving seat 35 moves to one side of the bracket 11 along the moving screw 34, the rotating part of the moving motor 33 reverses and drives the moving seat 35 to move to the other side of the bracket 11. When the moving seat 35 moves to the other side of the bracket 11, the rotating part of the moving motor 33 drives the moving screw 34 to start rotating forward again, and then the moving seat 35 drives the grinding wheel 6 to move back and forth alternately on the workpiece;

[0036] During the movement of the movable seat 35, the grinding motor 4 drives the grinding wheel 6 to rotate inside the protective frame 7 through the driving shaft 56, and the workpiece is ground by the grinding wheel 6. In addition, when the driving shaft 56 rotates, it drives the push block 57 to rotate synchronously. When the push block 57 rotates with the driving shaft 56, it pushes the piston rod 55 out of the slot, and then the piston rod 55 introduces the lubricant inside the push cylinder 52 into the liquid dispensing tube rack 54 through the second one-way valve, and the lubricant is pushed to the outside of the grinding wheel 6 through the liquid dispensing tube rack 54, and then the grinding wheel 6 is ground. Lubrication is performed. At this time, when the push block 57 pushes the piston rod 55, the friction force is reduced by the collar, and the first one-way valve is in a closed state during the oil pushing process; when the push block 57 rotates past the end of the piston rod 55, the piston rod 55 moves its end toward the drive shaft 56 under the action of the spring, and then the piston rod 55 drives the collar to move inside the groove, and then the second one-way valve is closed, while the first one-way valve is opened and the lubricant in the lubrication box 51 is drawn into the inside of the push cylinder 52 through the liquid guide tube 53 through the reverse movement of the piston rod 55 to repeat the next push of the lubricant.

[0037] 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, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
