Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a grinding device for plastic mold processing. Background Technique

[0002] Grinding in plastic mold processing is a very important process, which directly affects the surface quality of the mold and the appearance and performance of the final product. The grinding process is usually used to improve the surface roughness of the mold, remove processing marks, improve the surface finish of the mold, and prepare for the subsequent polishing process.

[0003] When grinding the mold, it is necessary to remove the surface roughness, and usually multiple surfaces of the mold need to be ground. However, most equipment can only grind one surface of the mold during the grinding operation, which means that after finishing the grinding of one surface, it is necessary to adjust the position of the mold or use other corresponding equipment to continue grinding other surfaces, which increases the complexity and time consumption of the processing procedure to a certain extent, especially when grinding a cylindrical mold.

[0004] In summary, there is an urgent need for a grinding device for plastic mold processing that can perform multi-directional grinding to solve the above problems Content of the Utility Model

[0005] In order to overcome the shortcoming that most equipment can only grind one surface of the mold during the grinding operation, which means that after finishing the grinding of one surface, it is necessary to adjust the position of the mold or use other corresponding equipment to continue grinding other surfaces, the utility model provides a grinding device for plastic mold processing that can perform multi-directional grinding.

[0006] The technical solution of the utility model is: a grinding device for plastic mold processing, including a support frame, a double-shaft motor, a grinding disc, a connecting rod, a grinding rod, a screw, a rodless cylinder, a grinder, a stabilizing rod and a pull rod. A double-shaft motor is installed on the support frame, and a grinding disc is connected to the output shaft of the double-shaft motor. Three connecting rods are rotatably connected to the support frame at equal intervals. Grinding rods are connected to all three connecting rods through screws. A rodless cylinder is connected to the left side of the support frame, and a grinder is connected to the slider on the rodless cylinder. A stabilizing rod is slidably connected to the support frame, and the stabilizing rod is snap-connected to the connecting rod. A pull rod is connected to the front side of the stabilizing rod.

[0007] As a preferred technical solution of the utility model, it further includes a connecting shaft, a large gear, a fixing plate, a lead screw and a small gear. A connecting shaft is connected to the output shaft of the double-shaft motor. A large gear is rotatably connected to the support frame. A fixing plate is connected to the right side of the large gear. A lead screw is threadedly connected to the fixing plate. A small gear is connected to the front connecting rod, and the small gear meshes with the large gear.

[0008] As a preferred technical solution of the present utility model, it further includes a threaded rod, a guide rod, a moving block, a damping block, a turning plate, a limiting plate and a rotating disc. The threaded rod is rotatably connected to the rear side of the support frame, the guide rod is arranged on the side far from the threaded rod, the moving block is threadedly connected to the threaded rod, the turning plate is rotatably connected to the moving block, damping blocks are connected to the left and right sides of the moving block and the left and right sides of the turning plate, the limiting plate is connected to the side of the turning plate far from the moving block, and the rotating disc is arranged on the threaded rod.

[0009] As a preferred technical solution of the present utility model, it further includes an anti-slip sleeve, and the anti-slip sleeve is sleeved on the lead screw.

[0010] As a preferred technical solution of the present utility model, it further includes a protection plate, and the protection plate is connected to the limiting plate.

[0011] As a preferred technical solution of the present utility model, it further includes a handle, and the handle is arranged on the turning plate.

[0012] The beneficial effects of the present utility model are as follows: 1. By starting the double-shaft motor and the grinding device, the output shaft of the double-shaft motor drives the grinding disc to rotate, and the grinding disc rotates in the opposite direction to the grinding device. The rotating design in the opposite direction helps to improve the grinding efficiency and flatness, and the grinding disc and the grinding device rotate in the same direction, causing the mold to rotate accordingly. The grinding rod will contact the side surface of the mold and perform grinding operations, and the side surface of the mold can be ground.

[0013] 2. The output shaft of the double-shaft motor drives the connecting shaft and the large gear to rotate. The large gear meshes with the small gear, thereby driving the front connecting rod and the grinding rod to rotate. The grinding rod rotates in the opposite direction to the mold, so as to improve the grinding efficiency and flatness.

[0014] 3. By holding the rotating disc and rotating it, the rotating disc drives the threaded rod to rotate. As the threaded rod rotates, the moving block moves downward along the thread of the threaded rod. The guide rod can ensure that the moving block moves smoothly downward in a straight line, and then drives the turning plate to also move downward. When the turning plate continues to move downward, the limiting plate will contact the mold, thereby fixing the mold. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0023] Embodiment 1: A grinding device for plastic mold processing, as Figures 1 - 4 shown, includes a support frame 1, a biaxial motor 2, a grinding disc 3, connecting rods 4, grinding rods 5, screws 6, a rodless cylinder 7, a grinder 8, a stabilizing rod 9, and a pull rod 10. A biaxial motor 2 is installed on the support frame 1. A grinding disc 3 capable of grinding the mold is fixedly connected to the output shaft of the biaxial motor 2. Three connecting rods 4 are rotatably connected to the support frame 1 at equal intervals. Grinding rods 5 capable of grinding the side of the mold are connected to the three connecting rods 4 through screws 6, and the grinding rods 5 can be disassembled and replaced. A rodless cylinder 7 is fixedly connected to the left side of the support frame 1. A grinder 8 is fixedly connected to the slider of the rodless cylinder 7. A stabilizing rod 9 is slidably connected to the support frame 1, and the stabilizing rod 9 is snap-connected to the connecting rod 4. A pull rod 10 is fixedly connected to the front side of the stabilizing rod 9.

[0024] When multi-directional grinding of the mold is required, the operator first places the corresponding mold on the grinding disc 3. Then, the operator can start the rodless cylinder 7, and the slider drives the grinder 8 to move downward until the grinder 8 contacts the surface of the mold. At this time, the rodless cylinder 7 is turned off to keep the position of the grinder 8 fixed. Subsequently, the operator starts the dual-axis motor 2 and the grinder 8. The output shaft of the dual-axis motor 2 drives the grinding disc 3 to rotate, and the grinding disc 3 and the grinder 8 rotate in opposite directions. This design of opposite-direction rotation helps to improve the grinding efficiency and flatness. The grinder 8 and the grinding disc 3 can grind both sides of the mold. In addition, the grinding rod 5 plays a limiting role and can fix the mold to prevent the mold from deviating from the grinding disc 3 or the grinder 8 due to the force during the grinding process. If the side of the mold needs to be ground, the operator starts the dual-axis motor 2 and the grinder 8, so that the grinding disc 3 and the grinder 8 rotate in the same direction, causing the mold to rotate accordingly. The grinding rod 5 will contact the side of the mold and perform the grinding operation, so that the side of the mold can be ground. Through the coordinated action of the grinding disc 3, the grinder 8, and the grinding rod 5, effective grinding of all sides of the mold can be achieved. When the surface of the grinding rod 5 is worn and needs to be replaced, the operator first unscrews the fixing screw 6 from the grinding rod 5 and the connecting rod 4, and the grinding rod 5 can be detached from the connecting rod 4 to facilitate the replacement with a new grinding rod 5. The stabilizing rod 9 plays an important limiting role. The stabilizing rod 9 can fix the connecting rod 4 to prevent the rotation of the mold during grinding from driving the connecting rod 4 and the grinding rod 5 to rotate together, avoiding the weakening of the grinding effect caused by the rotation of the connecting rod 4 and the grinding rod 5. And the operator can pull the pull rod 10 to make the stabilizing rod 9 move forward. When the stabilizing rod 9 no longer limits the connecting rod 4, the operator rotates the connecting rod 4 to adjust the contact surface between the grinding rod 5 and the mold. After adjustment, the stabilizing rod 9 can be reset.

[0025] Embodiment 2: On the basis of Embodiment 1, as Figure 4 shown, it further includes a connecting shaft 11, a large gear 12, a fixing plate 13, a lead screw 14, and a small gear 15. A connecting shaft 11 capable of driving the large gear 12 to rotate is fixedly connected to the output shaft of the dual-axis motor 2. The large gear 12 is rotatably connected to the support frame 1. A fixing plate 13 is fixedly connected to the right side of the large gear 12. A lead screw 14 capable of connecting the connecting shaft 11 and the large gear 12 is threadedly connected to the fixing plate 13. A small gear 15 is fixedly connected to the front connecting rod 4, and the small gear 15 meshes with the large gear 12.

[0026] When grinding the side of the mold, since some surfaces of the mold are inconvenient to grind and the contact area is small, the grinding effect is affected. The grinding disc 3 and the grinder 8 rotate in the same direction, driving the mold to rotate. The operator first pulls the stabilizing rod 9 outwards by a certain distance, so that the front connecting rod 4 is not clamped to the stabilizing rod 9, while the left and right connecting rods 4 are still clamped to the stabilizing rod 9. The output shaft of the dual-axis motor 2 drives the connecting shaft 11 and the large gear 12 to rotate. The large gear 12 meshes with the small gear 15, thereby driving the front connecting rod 4 and the grinding rod 5 to rotate. The grinding rod 5 rotates in the opposite direction to the mold, so as to improve the grinding efficiency and flatness. When it is not necessary for the connecting rod 4 and the grinding rod 5 to rotate, the operator rotates the screw rod 14. The screw rod 14 moves outwards along the thread on the fixed plate 13. The screw rod 14 no longer connects the connecting shaft 11 and the large gear 12. When the connecting shaft 11 rotates, it will not drive the large gear 12 to rotate. Then, the stabilizing rod 9 can be reset.

[0027] As Figure 4 and Figure 5 shown, it also includes a threaded rod 17, a guide rod 18, a moving block 19, a damping block 191, a turning plate 20, a limiting plate 21 and a rotating disc 22. The rear side of the support frame 1 is rotatably connected to the threaded rod 17. A guide rod 18 is welded on the side far from the threaded rod 17. The threaded rod 17 is threadedly connected with a moving block 19 that can move up and down, and the moving block 19 is slidably connected to the guide rod 18. The turning plate 20 is rotatably connected to the moving block 19. Damping blocks 191 that can increase friction are fixedly connected to the left and right sides of the moving block 19 and the left and right sides of the turning plate 20. A limiting plate 21 that can limit the mold is fixedly connected to the side of the turning plate 20 away from the moving block 19. A rotating disc 22 that is convenient for rotating the threaded rod 17 is welded on the threaded rod 17.

[0028] In addition, when only a single surface of some molds needs to be ground, the operator places the surface that does not need to be ground upwards on the grinding disc 3. The operator rotates the turning plate 20. The turning plate 20 rotates on the moving block 19. The damping block 191 increases the friction, so that the turning plate 20 has a certain stability when rotating. When the turning plate 20 reaches the appropriate position, the operator stops rotating. Next, the operator holds the rotating disc 22 and rotates it. The rotating disc 22 drives the threaded rod 17 to rotate. As the threaded rod 17 rotates, the moving block 19 moves downwards along the thread of the threaded rod 17. The guide rod 18 can ensure that the moving block 19 moves smoothly downwards in a straight line, and then drives the turning plate 20 to also move downwards. When the turning plate 20 continues to move downwards, the limiting plate 21 will contact the mold, thereby fixing the mold. The limiting plate 21 can ensure that the mold does not move during the grinding process, thus ensuring the grinding quality and safety. At this time, the operator can stop rotating the rotating disc 22, and the threaded rod 17 adjusts the positions of the moving block 19 and the turning plate 20 according to the height of the mold.

[0029] As Figure 4 shown, it further includes an anti-slip sleeve 16. The anti-slip sleeve 16 is sleeved on the lead screw 14. When the lead screw 14 is rotated, the anti-slip sleeve 16 can increase the stability of gripping, thereby reducing the problem of dropping off.

[0030] As Figure 6 shown, it further includes a protection plate 23. The protection plate 23 is fixedly connected to the limit plate 21 to prevent the limit plate 21 from generating excessive pressure when contacting the mold, which may cause damage to the mold.

[0031] As Figure 5 shown, it further includes a handle 24. The handle 24 is welded on the turning plate 20, which is convenient for the operator to hold the handle 24 and rotate the turning plate 20, thereby adjusting the position of the turning plate 20.
