Description

Technical Field

[0001] This invention relates to the field of plastic mold processing technology, specifically to an automated plastic mold processing equipment. Background Technology

[0002] The essence of plastic mold processing equipment is a specific combination of a series of precision mechanical devices with metal processing as the core. It is necessary to use metal processing equipment such as CNC milling machines, lathes, and EDM machines to cut and grind high-hardness mold steel in order to create the cavity of molded plastic products.

[0003] Patent publication number CN117754299B relates to the field of plastic mold processing technology, including a fixing block; the fixing block has handrails symmetrically installed on the front and back of its right end face, universal wheels evenly installed on the lower end face of the fixing block, and a T-shaped plate slidably installed on the left end face of the fixing block via an electric slider. A top plate is installed on the upper end face of the vertical section of the T-shaped plate, and a hydraulic cylinder is installed on the upper end face of the top plate via a fixing frame. A shaft column is installed on the telescopic section of the hydraulic cylinder, and the shaft column slides through the shaft plate. A pressure plate is installed on the lower end face of the shaft column, and a drilling mechanism is installed on the shaft column. A clamping mechanism is provided at the lower part of the T-shaped plate. This invention solves the problems that currently exist in the processing of ultra-large molds, where the mold needs to be aligned after being placed on the worktable of the machining center to ensure the accuracy of subsequent centering. However, the mold is heavy, and alignment is time-consuming and laborious, and it is easy to cause scratches on the mold, affecting its quality.

[0004] The aforementioned patent addresses issues such as heavy molds, time-consuming and labor-intensive alignment, and the ease with which molds are scratched, affecting their quality. However, the power switching process typically relies on operators manually cutting off the spindle power or using simple timing control, lacking a reliable mechanical interlock mechanism. During actual high-speed operation, due to vibration, control signal delays, or misoperation, the simultaneous operation of the rotary tool magazine's drive motor and the machining spindle's drive motor is highly likely, causing motion interference between the two transmission chains. This not only leads to inaccurate tool positioning and decreased machining accuracy but can also cause serious malfunctions such as mechanism jamming, damage to transmission components, and even motor burnout, severely impacting production efficiency and posing safety hazards. Furthermore, the tool magazine drive mechanism lacks an effective locking and holding device during machining, relying solely on solenoid valves or relays to maintain a de-energized state. This lack of stability means that vibrations during equipment operation can cause unexpected power re-engagement, resulting in unintended rotation of the tool magazine during machining. This can interrupt precision machining, scrap the workpiece, and potentially cause impact damage to the machine tool itself. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when the electric push rod moves down to exchange tools, the sliding ring presses down synchronously, pulling the collar away from the engagement with the output end of the motor through the slider and connecting rod. This action ensures that the connection between the motor and the countershaft is cut off when the rotating sleeve docks with the fixture. This effectively prevents the risk of motion interference, mechanism jamming, or even component damage caused by two power sources driving the transmission chain simultaneously. It fundamentally guarantees the safety and reliability of the power switching process. The collar can only be reset when the limit of the slider is released, ensuring that the state of the control device is stable and reliable throughout the tool changing and machining process. It will not be accidentally disconnected due to equipment vibration or external interference, strictly ensuring that the state of the motor being cut off continues until the machining is completed.

[0017] 2. In this invention, the sliding block and the limiting block are moved by the inclined surface contact drive, automatically releasing the fixation of the sub-shaft to the fixture. At the same time, the rotating buckle immediately supports the fixture, achieving a seamless transition of the fixing point. This process avoids loosening or shaking of the fixture during the handover process. The locking block, under the action of the spring, inserts into the limiting groove of the rotating sleeve, firmly locking the fixture and the rotating sleeve together. This rigid connection ensures that the power of the second motor can be transmitted to the tool efficiently and without loss, and resists cutting forces during the cutting process, minimizing vibration and deformation.

[0018] 3. In this invention, by squeezing the inclined surface of the groove, an additional force is generated that forces the rotating sleeve to axially adhere to the fixture. The higher the rotation speed, the greater the centrifugal force, and the stronger this locking force. This adaptive locking mechanism effectively counteracts the vibration and slight displacement that may occur under high-speed rotation, ensuring that the spindle and the tool maintain extremely high connection rigidity under high-speed, heavy-load cutting conditions, thereby guaranteeing machining accuracy and surface quality.

[0019] 4. In this invention, when the rotating clamping rod disengages from the inner wall of the fixture, it can rotate towards the tool, thus strengthening the fixation of the tool. The rotation of the clamping rod releases the obstruction of the limiting post, allowing the limiting post to move towards the inner wall of the sliding arc plate. The limiting post then clamps the rotating clamping rod, preventing it from releasing the tool due to inertia during high-speed rotation. When the rotation speed is too high, the rotating rod swings due to inertia, triggering the subsequent mechanism to further clamp the tool. This effectively counteracts the centrifugal force and vibration that may affect the tool during high-speed rotation, which could attempt to loosen it. This fundamentally prevents the extremely dangerous accident of tool ejection and ensures machining safety. Attached Figure Description

A fixing device for strengthening the fixation of the tool in fixture 9 when the rotation speed is too high is provided on the inner wall of fixture 9.

[0024] The control device includes a sliding ring 11, a slider 12, a connecting rod 16, and a collar 17. The sliding ring 11 is fixedly installed on the outer wall of the output end of the electric push rod 7. The slider 12 is slidably installed on the bottom of the fixed column 3. The collar 17 is slidably installed on the inner wall of the secondary shaft 5. A slot is provided on the inner wall of the collar 17. The outer wall of the slot matches the output end of the motor 6. The output end of the motor 6 contacts the inner wall of the slot. A sliding block is slidably installed on the outer wall of the collar 17. One end of the connecting rod 16 is rotatably connected to the sliding block, and the other end of the connecting rod 16 is rotatably connected to the slider 12.

[0025] The control device also includes a fixed sleeve 13, a sliding rod 14, and a push rod 15. The fixed sleeve 13 is fixedly installed at the bottom of the fixed column 3. The sliding rod 14 is slidably installed on the inner wall of the fixed sleeve 13. The push rod 15 is slidably installed at the bottom of the fixed column 3. The push rod 15 is in contact with the inner wall of the fixed sleeve 13. A square groove is provided on the side of the slider 12 near the sliding rod 14. The shape of the sliding rod 14 matches the square groove.

[0026] The control device also includes a slider 12 with an inclined surface on the side near the sliding ring 11. The inclined surface of the slider 12 is to facilitate the sliding ring 11 pushing the slider 12 to move towards the collar 17. The push rod 15 with an inclined surface on the side near the sliding ring 11 is to facilitate the sliding ring 11 pushing the push rod 15 to move towards the sliding rod 14. The surface of the sliding rod 14 has an inclined groove, and the push rod 15 contacts the inner wall of the inclined groove. An elastic element 1 is provided between the collar 17 and the secondary shaft 5. The elastic element 1 is provided to drive the collar 17 to reset. An elastic element 2 is provided between the fixed sleeve 13 and the sliding rod 14. The elastic element 2 is provided to drive the sliding rod 14 to move towards the slider 12.

[0027] In this embodiment, when it is necessary to cut a sheet metal into a plastic mold for molding plastic, the sheet metal needs to be placed inside the machine tool 1. Different cutting tools are used to cut and grind the surface of the sheet metal. When switching tools, the output end of motor 6 drives the secondary shaft 5 to rotate. The rotation of the secondary shaft 5 drives the surface fixture 9 to rotate. The rotation of the secondary shaft 5 will rotate the required tool below the electric push rod 7. Then the output end of the electric push rod 7 will extend towards the fixture 9, and the fixture 9 will dock with the rotating sleeve 10. After the fixture 9 docks with the rotating sleeve 10, the output end of the electric push rod 7 will push the fixture 9 downward. After the rotating sleeve 10 is docked, the output end of motor 8 will drive the fixture 9 to rotate. When the movable end of electric push rod 7 moves downward to push the rotating sleeve 10 to dock with the fixture 9, the movement of the output end of electric push rod 7 will drive the sliding ring 11 to move. The sliding ring 11 will contact the inclined surface of slider 12. The movement of slider 12 will push the connecting rod 16 to move. The movement of connecting rod 16 will push the collar 17 to move downward. The movement of collar 17 will disengage from the output end of motor 6. Therefore, when the rotating sleeve 10 docks with the fixture 9, motor 6 cannot drive the sub-shaft 5 to rotate. When electric push rod 7 moves downward to exchange tools, the sliding ring... 11. Simultaneous downward pressure pulls the collar 17 away from the output end of motor 6 via slider 12 and connecting rod 16. This action ensures that the connection between motor 6 and countershaft 5 is cut off when rotating sleeve 10 mates with fixture 9. This effectively prevents the risk of motion interference, mechanism jamming, or even component damage caused by two power sources simultaneously driving the transmission chain, fundamentally guaranteeing the safety and reliability of the power switching process. When slider 12 moves, it drives the square groove to move. When the position of the square groove coincides with the sliding rod 14, the sliding rod 14 moves towards the inside of the square groove to limit slider 12. The movement of sliding rod 14 drives the inclined groove. When the sliding rod 14 moves, it pushes the push rod 15 towards the sliding ring 11. When the sliding ring 11 resets, it contacts the inclined surface of the push rod 15 and pushes the push rod 15 to reset. When the push rod 15 resets, it contacts the inclined groove, and the push rod 15 pushes the sliding rod 14 to reset. The reset of the sliding rod 14 releases the limit on the slider 12. When the limit on the slider 12 is released, the collar 17 can reset, ensuring that the control device is stable and reliable throughout the tool changing and machining process. It will not be accidentally released due to equipment vibration or external interference, and strictly ensures that the power of the motor 6 is cut off until the machining is completed.

[0028] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the mold processing equipment further includes a fixing device and a limiting device.

[0029] The limiting device includes a sliding plate 21, a sleeve plate 22, a push plate 23, and a limiting plate 24. The sliding plate 21 is slidably installed on the inner wall of the rotating sleeve 10. The sleeve plate 22 is movably installed on the inner wall of the output end of the electric push rod 7. The sleeve plate 22 is fixedly connected to the sliding plate 21. An interface is provided on the side of the sleeve plate 22 near the motor 8. The shape of the interface matches the output end of the motor 8. The sleeve plate 22 slides through the inner wall of the rotating sleeve 10. A limiting groove is provided on the side of the output end of the electric push rod 7 near the limiting plate 24. The limiting plate 24 contacts the inner wall of the limiting groove. The push plate 23 is fixedly installed on the side of the sliding plate 21 near the limiting plate 24.

[0030] The limiting device also includes a sliding block 25, a limiting block 26, a fixing plate 27, a sliding plate 28, a locking block 29, a positioning rod 291, and a rotating buckle 292. The sliding block 25 is slidably mounted on the surface of the secondary shaft 5, the limiting block 26 is slidably mounted on the inner wall of the secondary shaft 5, and the sliding block 25 and the limiting block 26 are fixedly connected. The fixing plate 27 is fixedly mounted on the inner wall of the fixture 9, the sliding plate 28 is slidably mounted on the inner wall of the fixture 9, the locking block 29 is fixedly mounted on the side of the sliding plate 28 away from the fixing plate 27, the inner wall of the rotating sleeve 10 is provided with a limiting groove, the shape of the locking block 29 matches the limiting groove, the positioning rod 291 is fixedly mounted on the side of the sliding plate 28 near the locking block 29, the rotating buckle 292 is slidably mounted on the inner wall of the secondary shaft 5, the fixture 9 is provided with a sliding groove on the side near the rotating buckle 292, and the rotating buckle 292 contacts the inner wall of the sliding groove.

[0031] The limiting device also includes an elastic element three between the sliding plate 21 and the rotating sleeve 10, which is used to drive the sliding plate 21 to move away from the motor 28; an elastic element four between the limiting plate 24 and the rotating sleeve 10, which is used to drive the limiting plate 24 to move away from the electric push rod 7; an elastic element five between the sliding plate 28 and the fixed plate 27, which is used to push the sliding plate 28 to move away from the fixed plate 27; the side of the sliding block 25 closest to the rotating sleeve 10 is set as an inclined surface; and an elastic element six between the limiting block 26 and the secondary shaft 5, which is used to drive the limiting block 26 to move towards the fixture 9.

[0032] The fixing device includes a fixing ring 31 and a sliding key 32. The fixing ring 31 is fixedly installed on the top of the fixture 9, and the sliding key 32 is slidably installed on the inner wall of the fixing ring 31. A positioning plate is fixedly installed on the side of the rotating sleeve 10 near the fixing ring 31. A pressure groove is opened on the side of the positioning plate near the sliding key 32, and the side of the pressure groove near the sliding key 32 is set as an inclined surface.

[0033] The fixing device also includes a rotating rod 33, a pushing rod 34, a sliding arc plate 35, a rotating clamping rod 36, and a limiting post 37. The rotating rod 33 is rotatably mounted on the outer wall of the fixture 9, the sliding arc plate 35 is slidably mounted on the inner wall of the fixture 9, one end of the pushing rod 34 is slidably mounted on the inner wall of the rotating rod 33, and the other end of the pushing rod 34 is rotatably connected to the sliding arc plate 35. The rotating clamping rod 36 is rotatably mounted on the inner wall of the sliding arc plate 35, and the limiting post 37 is slidably mounted on the bottom of the inner wall of the sliding arc plate 35.

[0034] The fixing device also includes a sliding key 32 with an inclined surface on the side near the pressure groove, an elastic element 7 between the sliding key 32 and the fixing ring 31, the elastic element 7 being provided to drive the sliding key 32 to reset, a torsion spring between the rotating clamping rod 36 and the sliding arc plate 35, the torsion spring being provided to drive the rotating clamping rod 36 to rotate in the direction of the tool, a limiting post 37 sliding through the outer wall of the sliding arc plate 35, an elastic element 8 being provided between the limiting post 37 and the sliding arc plate 35, the elastic element 8 being provided to drive the limiting post 37 to slide inward into the sliding arc plate 35.

[0035] In this embodiment, when the rotating sleeve 10 moves downward, it contacts the inclined surface of the sliding block 25. The rotating sleeve 10 then pushes the sliding block 25 away from the fixed plate 27. The movement of the sliding block 25 causes the limiting block 26 to move, releasing the fixing of the fixture 9. The rotating buckle 292 then contacts the fixture 9 to support it. The movement of the limiting block 26 causes it to lose its pushing force on the positioning rod 291, allowing the sliding plate 28 to push the positioning rod 291 away from the fixed plate 27. The movement of the sliding plate 28 pushes the locking block 29 to move. After the rotating sleeve 10 engages with the fixture 9, the locking block 29 inserts into the limiting plate 27. When the device 9 is fixed to the inner wall of the slot, the rotating sleeve 10 will be fixed. When the output end of the electric push rod 7 pushes the rotating sleeve 10 to continue moving downward, the device 9 will push the rotating buckle 292 to move towards the inner wall of the secondary shaft 5. The device 9 can then continue to move downward. Through the inclined surface contact, the sliding block 25 and the limiting block 26 move, automatically releasing the fixation of the device 9 by the secondary shaft 5. At the same time, the rotating buckle 292 immediately supports the device 9, realizing a seamless transition of the fixed point. This process avoids the device 9 from becoming loose or shaking during the handover process. The locking block 29 is inserted into the limiting slot of the rotating sleeve 10 under the action of the spring, firmly locking the device 9 and the rotating sleeve 10 into one piece. This rigid connection ensures that the power of motor 8 can be efficiently and losslessly transmitted to the tool, resisting cutting forces during cutting and minimizing vibration and deformation. When the rotating sleeve 10 moves downward, the sliding plate 21 inside the rotating sleeve 10 contacts the top of the fixture 9, which in turn pushes the sliding plate 21 upward. The upward movement of the sliding plate 21 pushes the sleeve plate 22 upward, which engages with the output end of motor 8. Motor 8 then drives the fixture 9 to rotate. When the sliding plate 21 moves, it drives the push plate 23 to move. The movement of the 3rd movement will release the push on the limit plate 24, allowing the limit plate 24 to move away from the output end of the electric push rod 7. This allows the rotating sleeve 10 to rotate. Only when the fixture 9 and the rotating sleeve 10 are physically aligned will the fixture 9 lift the sliding plate 21, thereby pushing the sleeve 22 to engage with the output end of the second motor 8. This ensures that the timing of power transmission is absolutely correct and avoids the risk of motion interference, mechanism jamming, or even component damage caused by the second motor 8 driving the rotating sleeve 10 to rotate. This fundamentally guarantees the safety and reliability of the power switching process.

[0036] When the rotating sleeve 10 moves downward, it pushes the positioning plate to move. The movement of the positioning plate will drive the pressure groove to move. When the positioning plate contacts the surface of the fixture 9, the position of the pressure groove will coincide with the sliding key 32. When the fixture 9 rotates at high speed, the sliding key 32 will move away from the fixed ring 31, and then the sliding key 32 will contact the inner wall of the pressure groove. When the sliding key 32 continues to move away from the fixed ring 31, the sliding key 32 will press the inclined surface of the pressure groove, and the positioning plate and the fixture 9 will fit more tightly. When the high-speed rotation, the contact between the sliding key 32 and the inclined groove will strengthen the fixation between the rotating sleeve 10 and the fixture 9. When the fixture 9 rotates at high speed, the sliding key 32 moves outward under the action of centrifugal force. By squeezing the inclined surface of the pressure groove, an additional force is generated that forces the rotating sleeve 10 and the fixture 9 to fit axially. The higher the rotation speed, the greater the centrifugal force, and the stronger this locking force. This adaptive locking mechanism effectively counteracts vibrations and slight displacements that may occur during high-speed rotation, ensuring extremely high connection rigidity between the spindle and the tool under high-speed, heavy-load cutting conditions. This guarantees machining accuracy and surface quality. When the speed of the fixture 9 is too high, the rotating rod 33 will rotate away from the tool due to the inertia of its in-situ rotation. The rotation of the rotating rod 33 will drive the push rod 34 to move, which in turn will push the sliding arc plate 35 downward. The downward movement of the sliding arc plate 35 will drive the rotating clamping rod 36 to move. When the movable clamping rod 36 disengages from the inner wall of the fixture 9, it can rotate towards the tool, thus strengthening the fixation of the tool. The rotation of the clamping rod 36 releases the obstruction of the limiting post 37, allowing the limiting post 37 to move towards the inner wall of the sliding arc plate 35. The limiting post 37 then clamps the clamping rod 36, preventing it from releasing its fixation due to inertia during high-speed rotation. When the rotation speed is too high, the rotating rod 33 swings due to inertia, triggering a subsequent mechanism to further clamp the tool. This effectively counteracts the centrifugal force and vibration that may cause the tool to loosen during high-speed rotation, fundamentally preventing the extremely dangerous accident of tool ejection and ensuring machining safety.
