Description

Technical Field

[0001] This invention relates to the field of mold parts processing equipment, specifically a mold slider processing device. Background Technology

[0002] In mold design and processing, slider forming is a classic, simple, and practical structure. However, during the slider processing, inclined guide pin holes are machined on the slider, and these inclined guide pin holes are machined diagonally downwards from the top surface of the slider. This results in burrs on the top surface of the slider that need to be removed. In addition, since the slider is a part that needs to move back and forth frequently, its bottom surface, i.e. the sliding surface, must be smooth and free of burrs. Therefore, in the subsequent polishing and deburring process, both the top and bottom surfaces of the slider need to be machined. These two surfaces are parallel, and when one is machined, the other surface will be facing downwards. For modern machining production, which is increasingly focused on time costs, the processing efficiency is very low. At the same time, the inclined surface of the slider, which is used to withstand the pressure of the impact, is often subjected to sliding friction under high loads. Therefore, this inclined surface also needs to be very smooth. However, this inclined surface is inclined in the horizontal direction along with both the top and bottom surfaces of the slider. Ordinary machining equipment cannot machine this inclined surface while polishing the top and bottom surfaces of the slider. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 9 This invention provides a technical solution: a mold slider processing device, including a base plate 1 and a horizontal moving device 2. The horizontal moving device 2 is fixedly installed on the base plate 1 and is used to place a slider 100. Sandpaper 3 is provided between the slider 100 and the horizontal moving device 2. The sandpaper 3 is conveyed by a sandpaper transmission component 4. Slide rail clamping components 5 are provided on both sides of the horizontal moving device 2. The slide rail clamping components 5 are used to limit the slider 100 from the side on the horizontal moving device 2 to prevent the slider 100 from swaying left and right. A top surface grinding device 6 is provided at the end of the slide rail clamping component 5. The top surface grinding device 6 is used to grind the top surface of the slider 100 and the opening of the inclined guide post.

[0038] In this embodiment, the base plate 1 is provided with a groove 11, and the horizontal moving device 2 is installed in the groove 11. This can reduce the height of the horizontal moving device 2, making its movement more stable, and the recessed design can also provide protection for the horizontal moving device 2.

[0039] In this embodiment, the horizontal moving device 2 includes a double-rod hydraulic cylinder 21, a connecting block 22, and a magnetic platform 23. The double-rod hydraulic cylinder 21 is installed in the groove 11, and the connecting block 22 is fixed on the output shaft of the double-rod hydraulic cylinder 21. The upper surface of the double-rod hydraulic cylinder 21 is provided with a guide strip 24, and the magnetic platform 23 is slidably connected to the guide strip 24. The magnetic platform 23 is connected to the double-rod hydraulic cylinder 21 through the connecting block 22 and can be driven to slide freely by the double-rod hydraulic cylinder 21. The upper surface of the magnetic platform 23 is provided with a first baffle 25 and a second baffle 26 arranged in parallel. The distance between the first baffle 25 and the second baffle 26 is greater than the width of the slider 100. 23 is a magnetic platform that can be controlled by a switch. Driven by the double-rod hydraulic cylinder 21, the magnetic platform 23 can be moved. The first baffle 25 and the second baffle 26 can block the slider 100, so that the slider 100 is always in the area between the first baffle 25 and the second baffle 26. It should be noted that the sandpaper 3 is located above the magnetic platform 23 and below the bottom surface of the slider 100. Therefore, the magnetic force of the selected magnetic platform 23 should not be too large. The frictional force generated by the attraction of the magnetic platform 23 on the slider 100 on the sandpaper 3 needs to be less than the traction force of the sandpaper transmission component 4 on the sandpaper 3, that is, the sandpaper 3 can move between the slider 100 and the magnetic platform 23.

[0040] In this embodiment, the sandpaper conveying assembly 4 includes a take-up roller 41, a guide roller 42, a pressing roller 43, and an unwind roller 44. The take-up roller 41 and the unwind roller 42 are respectively mounted on both ends of the horizontal moving device 2 via mounting brackets. The guide roller 42 is symmetrically arranged between the take-up roller 41 and the unwind roller 44. The pressing roller 43 is mounted on the horizontal moving device 2 and symmetrically arranged inside the guide roller 42. The take-up roller 41 and the unwind roller 44 are connected to an external take-up device such as a motor. Initially, the sandpaper is taken up by the take-up device on the take-up roller 41 and unwound by the unwind roller 44, so that the sandpaper can move on the lower surface of the slider 100 for polishing and grinding. After the sandpaper on the unwind roller 44 is unwound, it can be taken up by the take-up device on the unwind roller 44 and unwound by the take-up roller 41, so that the sandpaper 3 can be fully and cyclically utilized.

[0041] In this embodiment, the slide rail clamping assembly 5 includes a lower slide rail 51, an upper slide rail 52, a clamping assembly 53, and a touch switch 54. The lower slide rail 51 is mounted on the base plate 1 and symmetrically arranged on both sides of the groove 11. The upper slide rail 52 is fixed on the lower slide rail 51. The clamping assembly 53 is connected to the lower slide rail 51 and the upper slide rail 52 via connecting wheels 55. The clamping assembly 53 is used to fix the slider 100 from both sides. The touch switches 54 are respectively installed on both sides of the lower slide rail 51. The two ends of the top surface grinding roller 58 are rotatably installed in the upper slide rail 52. After the slider 100 is placed on the magnetic platform 23, since the magnetic force of the magnetic platform 23 is not very large, the slider 100 may shift when the sandpaper 3 moves, and may also be bounced up by the spring-loaded assembly 61. Therefore, the clamping assembly 53 fixes the slider 100 from both sides to prevent the slider 100 from shifting.

[0042] In this embodiment, the top surface polishing roller 58 includes a first polishing roller 581 and a second polishing roller 582. The second polishing roller 582 is located in the middle of the first polishing roller 581. The second polishing roller 582 has an elastic material inside to ensure that it can be compressed by the sliding block 100. When the sliding block 100 moves with the magnetic platform 23, it will press against the first polishing roller 581. The first polishing roller 581 will rotate under the drive of the sliding block 100. During this process, the polishing tool (which can be wrapped sandpaper or...) is set on the first polishing roller 581. The teeth on the roller will grind the top surface of the slider 100. Since the size of the second grinding roller 582 is larger than that of the first grinding roller 581 and its internal material is an easily compressible material such as polyurethane, and the width of the second grinding roller 582 is greater than the width of the inclined guide post hole, it will be compressed by the top surface when the slider 100 passes through. However, since the position of the inclined guide post hole is empty, a part of the second grinding roller 582 will extend into the inclined guide post hole to rub and grind the opening of the inclined guide post hole, thus enabling the opening of the inclined guide post hole to be ground.

[0043] In this embodiment, the upper slide rail 52 is provided with a slot 521, and the connecting wheel 55 is engaged in the slot 521. The engagement of the connecting wheel 55 with the slot 521 can prevent the clamping component 53 from being misaligned, which would cause the slider 100 to deviate.

[0044] In this embodiment, the gripping assembly 53 includes a suction cup 531, an air valve 532, and air nozzles 533 located on both sides of the air valve 532. The suction cup 531 is connected to the air valve 532, and the air valve 532 is connected to the connecting wheel 55 via a connecting rod. The air nozzles 533 are in a sealed state when they do not touch the touch switch 54. The two air nozzles 533 correspond to the two touch switches 54 respectively. The two touch switches 54 respectively perform the inflation and deflation operations through the air valve 532, thereby controlling the suction cup 531 to adsorb and release the slider 100.

[0045] In this embodiment, the touch switch 54 includes a switch base 541 and an air valve switch 542. The switch base 541 is fixed to the side of the lower slide rail 51. The air valve switch 541 can charge and de-air the clamping assembly 53. When the air valve 533 on one side is connected to the air valve switch 542, air can be charged and de-aired into the air valve 532 through the air valve switch 542. The operations performed by the air valve switches 542 on both sides are opposite, that is, when the air valve switch 542 on one side is evacuating, the air valve switch 542 on the other side is charging.

[0046] In this embodiment, the top surface grinding device 6 includes a spring-loaded assembly 61, an inclined slide rail 62, a top surface grinding plate 63, a stand 64, and a rotating shaft 65. The spring-loaded assembly 61 is located at the end of the slide rail clamping assembly 5. The spring-loaded assembly 61 is used to spring up the slider 100 and enable it to move onto the inclined slide rail 62. The inclined slide rail 62 is fixed on the base plate 1. The top surface grinding plate 63 is mounted on the stand 64 via the rotating shaft 65. Both ends of the rotating shaft 65 are rotatably connected to the stand 64, and both ends of the rotating shaft 65 are provided with damping rings 66. The spring-loaded assembly springs up the tail of the slider 100 to a certain height, allowing the slider to move onto the inclined slide rail 62. The tail of block 100 can be raised, and under the drive of the double-rod hydraulic cylinder 21, the slider 100 moves to the inclined slide rail 62. When the tail of slider 100 is raised, the top surface of slider 100 contacts the top surface grinding plate 63. During the continuous movement of slider 100 towards the inclined slide rail 62, the top surface grinding plate 63 continuously grinds the top surface under the pressure of the damping ring 66 on the top surface grinding plate 63 and the movement of slider 100. Several oil grooves are provided on the top surface grinding plate 63 to store lubricating oil. This oil will flow to the top or bottom surface of the slider, which can play the role of lubrication and preventing the generation of metal dust.

[0047] In this embodiment, the spring-loaded assembly 61 includes a spring-loaded block 611, a torsion spring 612, a fixed bracket 613, and a torsion spring shaft 614. The spring-loaded block 611 contains a torsion spring 612 mounted on the torsion spring shaft 614. One elastic arm of the torsion spring 612 rests on the spring-loaded block 611, and the other elastic arm rests on the fixed bracket 613. The fixed bracket 613 is fixed to the base plate 1. When the rear half of the slider 100 moves above the spring-loaded block 611, the magnetic suction platform 23 is closed, causing the spring-loaded block 611 to spring up the rear end of the slider 100, allowing the slider 100 to move onto the inclined slide rail 62 under the drive of the double-rod hydraulic cylinder 21.

[0048] Working principle: First, the magnetic platform 23 is moved to the side near the take-up roller 41 via the double-rod cylinder 21. Then, the rear end of the slider 100 is pressed against the baffle 26, which provides positioning for the slider 100 and prevents different operators from placing the slider 100 arbitrarily. The suction cup 531 is attached to the side of the slider 100, and the suction is applied by the air valve 542 on this side, causing the suction cup 531 to adhere to the slider 100. Then, the air valve 532 is closed, and the take-up roller 41 and the double-rod cylinder 21 are opened, causing the sandpaper 3 to move towards the take-up roller 41. This causes the slider 100 to move towards the unwind roller 44 on the magnetic platform 23, thus allowing the sandpaper to... 3. Relative movement occurs between the slider 100 and the sandpaper 3. Simultaneously, the slider 100 is moved by the friction of the sandpaper 3 to the position where it touches the baffle 25. It stops moving with the sandpaper 3 under the obstruction of the baffle 25, thus allowing the bottom surface of the slider 100 to be polished. As the slider 100 moves with the magnetic platform 23, it presses against the polishing roller 581. The polishing roller 581 rotates under the influence of the slider 100. During this process, the polishing tool on the polishing roller 581, such as wrapped sandpaper or the serrated edge of the roller, polishes the top surface of the slider 100. Then, due to the larger size of the polishing roller 582... The first grinding roller 581 is made of a compressible material such as polyurethane, and the width of the second grinding roller 582 is greater than the width of the inclined guide post hole. When the slider 100 passes through, it will be compressed by its top surface. However, since the position of the inclined guide post hole is empty, a part of the second grinding roller 582 will extend into the inclined guide post hole to rub and grind the opening of the inclined guide post hole. This allows the opening of the inclined guide post hole to be ground. At this time, the slider will move together with the clamping assembly 53. Then, when the air nozzle 533 touches the air nozzle switch 542 on the other side, air is injected into the suction cup 531 through the air nozzle switch 542, causing the slider 100 to detach from the suction cup 531. At this position, the tail of slider 100 is above the spring-loaded assembly 61. The magnetic force of the magnetic platform 23 is turned off at this position, and the spring-loaded block 611 will lift the rear end of slider 100. During the lifting process, it will press the top surface grinding plate 63 upward, so that the top surface grinding plate 63 maintains pressure on the top surface of slider 100. Finally, under the drive of the double-rod hydraulic cylinder 21 and the obstruction of the baffle 25, slider 100 will move obliquely upward along the inclined slide rail 62. During the movement, the top surface of slider 100 can be ground. After the grinding is completed, the operator visually inspects and judges whether the grinding needs to be repeated. If so, the above process is repeated.

[0049] Based on the above, the horizontal moving device of this invention can polish the lower surface of the slider while moving the slider to remove burrs from the lower surface of the slider; the horizontal moving device of this invention is linked with the slide rail clamping assembly and the top surface polishing device, and when polishing the bottom surface of the slider, the state of the slider is adjusted so that the top surface polishing device can polish the top surface of the slider.

[0050] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
