Description

Technical Field

[0001] The invention relates to the technical field of mold processing equipment, and in particular to a carving and milling machine for mold processing. Background Art

[0002] Engraving and milling machines are a type of CNC machine tools. Engraving and milling machines are generally considered to be CNC milling machines that use small tools, high-power and high-speed spindle motors. The advantage of engraving machines is engraving, and if the hardness of the processed material is relatively high, it will appear to be unable to do it. The emergence of engraving and milling machines can be said to fill the gap between the two.

[0003] When today's engraving and milling machines are processing molds, in order to improve the stability of mold processing, it is necessary to fix the mold raw material on the processing table. The traditional fixing method is to manually connect the raw material with the clamping structure, and then fix the clamping mechanism on the processing table. The fixing method is cumbersome, and because the mold raw material needs to be fixed inside the engraving and milling machine, there are certain safety hazards. When the mold raw material is fixed, it is necessary to measure the front, back, left and right distance dimensions of the mold fixed on the work table, and then import the specific coordinates of the mold into the engraving and milling machine. This method of processing has measurement errors, which causes deviations in the processing of mold raw materials that are not fixed in the corresponding position, resulting in processing defective products and affecting the mold processing efficiency.

[0004] Based on this, a carving and milling machine for mold processing is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problem and to provide a milling machine for mold processing.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A milling machine for mold processing, comprising a machine body, a spindle motor and a control panel connected to the machine body, a tool connected to the output end of the spindle motor, a workbench slidably connected to the machine body, a telescopic cover connected to the workbench, and a T-slot opened on the workbench;

[0011] Preferably, a card slot is provided on the push bar, a card block is connected in the card slot, a connecting rod is connected to one side of the card block, and an adjustment plate is connected to the other end of the connecting rod.

[0012] Preferably, the transmission mechanism includes a slide bar 1 and a slide bar 2, a connecting rod is connected between the slide bar 1 and the slide bar 2, the fixed frame is connected to a slide rail plate by bolts, a transverse groove and an arc groove are provided on the slide rail plate, one end of the arc groove is connected to the middle part of the transverse groove, the slide rail plate is rotatably connected to a pinion gear through an axis, the pinion gear is fixedly connected to a bevel gear 1 through an axis, one end of the rotating shaft is connected to a bevel gear 2, the bevel gear 1 and the bevel gear 2 are meshed with each other, one end of the slide bar 2 is connected to a large gear, the outer side of the slide rail plate is rotatably connected to a telescopic cylinder, the telescopic end of the telescopic cylinder is connected to a ring, and the ring is sleeved on the slide bar 1.

[0013] Preferably, the second slide bar is slidably connected to the transverse groove, and the first slide bar is slidably connected to a part of the structure of the arc groove and the transverse groove.

[0014] Preferably, the sleeve is sleeved on one end of the sliding rod.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. The present application adopts a fixed clamp structure and utilizes the fixed clamp to clamp the mold raw material. Since the fixed clamp moves toward the mold from both sides of the mold, when clamping the mold, the mold can always be kept in the center of the workbench. When processing the same batch of molds, it is only necessary to adjust the distance between the fixed clamp and the clamping plate. When processing the mold subsequently, it is only necessary to place the mold stably on the workbench, which simplifies the fixing operation of the mold before processing and improves the mold processing accuracy and efficiency.

The present application adopts an adjustment plate structure and utilizes the adjustment plate to correct the position of the mold, so that before the mold is fixed, the mold can be pushed to the middle position of the workbench by relying on the adjustment plate, and then the mold can be clamped and fixed from both sides. Since the adjustment plate structure is replaceable, the equipment can pre-position molds of different sizes to ensure post-processing accuracy. The operator only needs to place the mold raw material on the workbench close to one end of the adjustment plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , the present invention provides a technical solution:

[0028] A milling machine for mold processing, comprising a machine body 1, a spindle motor 2 and a control panel 3 are connected to the machine body 1, a tool is connected to the output end of the spindle motor 2, and the spindle motor 2 is used to drive the tool to rotate to realize milling of the mold raw material, wherein the spindle motor 2 structure can move, and the workbench 4 structure can also move in the machine body 1, and the moving track of the spindle motor 2 and the moving ring track of the workbench 4 are perpendicular to each other, the machine body 1 is slidably connected with the workbench 4, and the workbench 4 is connected with a telescopic cover 5, and the telescopic cover 5 structure can be telescoped with the movement of the workbench 4, and the telescopic cover 5 plays the effect of preventing iron filings from falling into the machine body 1, and the workbench 4 is provided with a T-slot 6, and the T-slot 6 plays the effect of positioning the mold coordinates. The above structures are the main structures of the current milling machine, and will not be described in detail here;

[0029] A sleeve block 14 is connected to the workbench 4, and a rotating shaft 31 is rotatably connected to the sleeve block 14. Two sleeve blocks 14 are provided, and the rotating shaft 31 is rotatably connected to the two sleeve blocks 14. A deflection rod 32 is connected to the rotating shaft 31, and the deflection rod 32 is arranged between the two sleeve blocks 14. One end of the deflection rod 32 is rotatably connected to the traction frame 13. A clamping plate 33 is arranged above the workbench 4, and an articulated frame 35 is connected to the clamping plate 33. The other end of the traction frame 13 is rotatably connected to the articulated frame 35. A fixed frame 8 is connected to the outside of the workbench 4, and a pushing bar 10 is arranged above the workbench 4. The pushing bar 10 is slidably connected to the workbench 4, and the pushing bar 10 and the clamping plate 33 are perpendicular to each other. Both ends of the pushing bar 10 are fixedly connected with sleeves 28, and the fixed frame 8 is connected to first drive the pushing bar 10 to move, push the engraving and milling machine processing mold to be placed in the center position of the workbench 4, and then drive the clamping plate 33 to move, so as to complete the transmission mechanism for clamping and fixing the processing mold.

[0030] Specifically, Figure 4 and Figure 5 As shown, the clamping plate 33 is connected to a limiting frame 36, and a threaded rod 37 is slidably connected to the clamping plate 33. The threaded rod 37 is connected to the clamping plate 33, and one end of the threaded rod 37 is connected to a fixing clamp 12. A nut is threadedly connected to the threaded rod 37, and the nut connected to the threaded rod 37 is arranged between the limiting frame 36 and the clamping plate 33. By rotating the nut, the distance between the fixing clamp 12 and the clamping plate 33 can be changed to achieve the effect of clamping molds of different sizes. This type of adjustment can be used when the telescopic cylinder 9 is extended to the maximum distance and still cannot clamp the mold.

[0031] Specifically, Figure 2 and Figure 5As shown, the lower end of the fixing clamp 12 is fixedly connected with a slider 34, and the slider 34 is slidably connected to the T-slot 6. The T-slot 6 is provided on the traditional engraving and milling machine mainly to fix the clamping mechanism. The clamping structure first continues to clamp the mold, and then the clamping structure is fixed on the T-slot 6. The position where the T-slot 6 is provided can assist in identifying the fixed position of the mold. The operator can understand the approximate fixed coordinates of the mold by observing that the mold is connected to different T-slots 6.

[0032] Specifically, Figure 4 As shown, a card slot 29 is provided on the push bar 10, and a card block 15 is connected in the card slot 29. A connecting rod 16 is connected to one side of the card block 15, and an adjustment plate 11 is connected to the other end of the connecting rod 16. The card block 15 structure can be easily removed from the card slot 29, so by replacing the connecting rods 16 of different lengths, the effect of pushing the mold to move different distances can be achieved, and the fixed position of the mold can be adjusted.

[0033] Specifically, Figure 4 As shown, the transmission mechanism includes a slide bar 19 and a slide bar 27, a connecting rod 26 is connected between the slide bar 19 and the slide bar 27, the slide bar 19 and the slide bar 27 are parallel to each other, and the two ends of the connecting rod 26 are respectively vertically fixedly connected to the slide bar 19 and the slide bar 27, and the fixed frame 8 is connected to the slide rail plate 7 by bolts, so that the slide rail plate 7 and the fixed frame 8 are an integrated structure, and the slide rail plate 7 is provided with a transverse groove 22 and an arc groove 23, and one end of the arc groove 23 is connected to the middle part of the transverse groove 22, and the slide rail plate 7 is connected to the pinion 17 through the shaft rotation, and the pinion 17 is fixed by the shaft It is connected to a bevel gear 24, which is rotatably connected to the slide plate 7. One end of the rotating shaft 31 is connected to a bevel gear 2 30, and the bevel gear 24 and the bevel gear 2 30 are meshed with each other. One end of the slide rod 27 is connected to a large gear 18, and the large gear 18 and the small gear 17 are on the same vertical plane. The outer side of the slide plate 7 is rotatably connected to a telescopic cylinder 9, and a sleeve 21 is connected to the telescopic end of the telescopic cylinder 9. The sleeve 21 is sleeved on the slide rod 19. When the telescopic cylinder 9 is extended, the sleeve 21 structure will rotate around the slide rod 19, and the movement of the sleeve 21 will drive the slide rod 19 to move.

[0034] Specifically, Figure 4 As shown, slide bar 27 is slidably connected to the transverse groove 22, slide bar 19 is slidably connected to the arc groove 23 and part of the structure of the transverse groove 22, slide bar 19 is slidably connected to the front half of the transverse groove 22, and slide bar 27 is slidably connected to the rear half of the transverse groove 22.

[0035] Specifically, Figure 4As shown, the sleeve 28 is sleeved on one end of the slide bar 27. When the slide bar 27 moves, it can drive the sleeve 28 to move synchronously, thereby driving the adjustment plate 11 to push the mold to move, and drive the mold to the position to be clamped, ensuring the accurate fixing position of the mold.

[0036] Specifically, Figure 2 and Figure 4 As shown, a sleeve 20 is fixedly connected to the outside of the telescopic cylinder 9, and a fixed shaft 25 is connected to the outside of the sleeve 20. The fixed shaft 25 is rotatably connected to the slide rail plate 7. The fixed shaft 25 penetrates and is rotatably connected to the slide rail plate 7. When the telescopic cylinder 9 continues to extend and retract, the fixed shaft 25 connected to the outside of the telescopic cylinder 9 will rotate on the slide rail plate 7. The horizontal height of the connection position of the fixed shaft 25 is lower than the horizontal height of the transverse groove 22. The fixed shaft 25 at this position will ensure that when the telescopic cylinder 9 is extended, the slide rod 19 is pushed into the arc groove 23 to ensure the continuity of the transmission.

[0037] In summary, the engraving and milling machine for mold processing provided in this embodiment, when the mold needs to be milled, the operator only needs to place the mold raw material on the workbench 4 close to the side of the push bar 10, and then control the telescopic cylinder 9 to extend, and use the ring 21 connected to the telescopic end of the telescopic cylinder 9 to push the slide bar 19 to slide on the transverse groove 22. Since the connecting rod 26 is fixedly connected between the slide bar 19 and the slide bar 27, the slide bar 27 slides synchronously on the transverse groove 22. When the slide bar 27 moves to contact one end of the transverse groove 22, the slide bar 27 stops moving. At this time, the large gear 18 and the small gear 17 connected to one end of the slide bar 27 are connected to each other to complete the meshing between the structures;

[0038] When the slide bar 27 slides on the transverse groove 22, the sleeve 28 sleeved on the slide bar 27 is driven to move, and the sleeve 28 is used to drive the push bar 10 to slide on the workbench 4. Since the push bar 10 is connected with the adjustment plate 11 structure, the push bar 10 is used to drive the adjustment plate 11 to push the mold placed on the workbench 4 to move it between the fixed clamps 12, and the mold is placed on the workbench 4. The horizontal position parallel to the side of the fixed clamp 12 is limited. By replacing the connecting rods 16 of different lengths, the pushing and correcting effect of molds of different sizes can be achieved, so that the equipment can meet the clamping and fixing requirements of molds of different sizes. When replacing the adjustment plate 11, it is only necessary to take out the card block 15 from the card slot 29, then replace the connecting rod 16 of different sizes, and then re-place the corresponding card block 15 in the card slot 29. The plane of the adjustment plate 11 that pushes the mold side can be replaced more on the outside of the mold, so as to adapt to the push correction requirements of molds with different outer structures. When the adjustment plate 11 pushes the mold to move, it is necessary to meet the maximum movement distance of the adjustment plate 11, and the adjustment plate 11 will not enter between the fixing clamps 12, so as to avoid contact between the fixing clamps 12 and the adjustment plate 11, resulting in structural collision and damage to the fixed structure of the mold;

[0039] When the large gear 18 and the small gear 17 are meshed, the telescopic cylinder 9 continues to be extended. At this time, the slide bar 27 structure stops sliding on the horizontal groove 22, and the adjustment plate 11 structure remains unchanged. At this time, the slide bar 19 starts to slide on the arc groove 23, and the slide bar 19 rotates around the slide bar 27. At this time, the slide bar 27 rotates, thereby driving the large gear 18 to rotate. By meshing with each other between the large gear 18 and the small gear 17, the small gear 17 rotates. Since the small gear 17 and the bevel gear 1 24 rely on each other, the small gear 17 rotates. The shaft is fixedly connected, and the shaft is rotatably connected to the slide rail plate 7. The bevel gear 1 24 drives the bevel gear 2 30 to rotate, thereby driving the rotating shaft 31 to rotate, and the deflection rod 32 connected to the outer side of the rotating shaft 31 is deflected, thereby pushing the traction frame 13 to deflect, and driving the clamping plate 33 to move toward the mold structure. When the clamping plate 33 drives the fixed clamp 12 to complete the clamping of the outer structure of the mold, the fixed clamp 12 stops moving. At this time, the telescopic cylinder 9 cannot continue to extend, and the mold structure maintains the clamped state;

[0040] When the fixing clamp 12 clamps the mold, the distance between the clamping plate 33 and the fixing clamp 12 can be adjusted by rotating the nut connected to the threaded rod 37, so that the clampable size can be fine-tuned. The nut structure is arranged between the limit frame 36 and the clamping plate 33, wherein the limit frame 36 is sleeved on the outside of the threaded rod 37, and a slider 34 structure is connected to the lower end of the fixing clamp 12. The slider 34 can be used to make the fixing clamp 12 stably slide on the workbench 4, ensuring that the two clamping side surfaces always remain parallel to each other during the sliding process of the fixing clamp 12, thereby improving the structural stability of the mold when clamping, and facilitating the subsequent processing of the mold by the engraving and milling machine tool. Since the mold is limited by the fixing clamp 12 and the adjustment plate 11 at the same time, the position coordinates of the mold when fixed are guaranteed to be accurate, thereby improving the subsequent processing accuracy. Since the fixing operation of the mold is simplified, the equipment can complete the rapid fixing and processing of the mold, thereby improving the processing efficiency of the mold.
