Description

Technical Field

[0001] This invention relates to the field of cutting and grinding equipment technology, specifically a cutting and grinding equipment for mold processing. Background Technology

[0002] In the mold manufacturing and finishing process, cutting and grinding equipment is a type of processing equipment used for cutting and blanking mold blanks and grinding and polishing the edges and surfaces after forming. It is a commonly used auxiliary tool in the mold processing field. It mainly relies on high-speed rotating cutting and grinding parts to remove workpiece material. It is usually equipped with a workpiece clamping structure and a feed operation platform. The operator controls the workpiece relative to the processing head to feed through manual or motor means to complete the roughing and semi-finishing of mold parts. It is widely used in the processing of small and medium-sized molds and accessories. However, the protective covers of existing cutting and grinding equipment usually do not have special locking parts, or use a simple snap-locking structure, which is very easy to loosen under continuous vibration of the equipment, causing the protective cover to open accidentally. When opening and closing, it requires precise manual alignment and locking, and the buckles are mostly exposed, which not only occupies external space, but also easily scratches and interferes with the workpiece to be processed, making it impractical. Meanwhile, the clamping fixtures on the device usually rely on a single threaded rod to adjust the stroke. Large-scale adjustments within the clamping range require continuous rotation of the threaded rod, which takes a long time for coarse adjustments and results in low workpiece clamping and adjustment efficiency.

[0018] 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.

[0019] Please see Figure 1-7 This invention provides a technical solution: a cutting and grinding device for mold processing, comprising a cabinet 1, a slide table 2 slidably connected to the cabinet 1, a protective cover 4 hinged to one end of the slide table 2, and a locking structure 5 provided between the other end of the slide table 2 and the protective cover 4. The locking structure 5 includes a connecting block 501, a limiting pin 502, an insertion hole 504, a locking component, and an anti-disengagement component. The connecting block 501 is fixedly connected to the side wall of the slide table 2, and the limiting pin 502 is slidably connected to the middle of the connecting block 501. An insertion hole 504 is provided on the inner end of the limiting pin 502. The protective cover 4 is provided with a locking component near the top of the connecting block 501, which can be inserted into the socket 504. The locking component is used to lock and position the protective cover 4 and the slide table 2. The protective cover 4 is equipped with an anti-disengagement component, which is used to limit the locking component from disengaging from the insertion position. The locking component includes a locking pin 505. The locking pin 505 is slidably connected to the protective cover 4. The cross-section of the locking pin 505 is "L" shaped. The lower end of the locking pin 505 penetrates the socket 504 downwards. The protrusion formed at the bottom end of the locking pin 505 abuts against the bottom surface of the limiting pin 502.

[0020] In specific use, the protective cover 4 is flipped downward during use; during the closing process, the limit pin 502 is pressed inward first, then the locking pin 505 on the protective cover 4 passes through the insertion hole 504 on the limit pin 502 along with the movement. After the protective cover 4 is completely closed in place, the limit pin 502 is released, the second spring 503 rebounds to push the limit pin 502 to reset outward, the inner wall of the insertion hole 504 tightly abuts against the shaft of the locking pin 505, meanwhile the L-shaped protrusion at the bottom of the locking pin 505 exactly abuts against the bottom surface of the limit pin 502 after the limit pin 502 resets, forming axial hook locking. The sliding chute 507 and the guide post 508 cooperate to constrain the sliding track of the locking pin 505, preventing deviation and falling out. At this time, locking after the protective cover 4 is closed is realized, which can effectively prevent the protective cover 4 from being accidentally lifted during processing and avoid the safety hazard of chip splashing.

[0021] The anti-dropping member comprises a sliding chute 507 and a guide post 508. The sliding chute 507 is opened at the center position of the locking pin 505, the guide post 508 is fixedly connected to the position on the protective cover 4 close to the sliding chute 507, and the guide post 508 is in sliding connection with the sliding chute 507. The locking structure 5 further comprises a second spring 503 and a handle 506, the second spring 503 is fixedly connected between the inner end of the limit pin 502 and the inner wall of the connecting block 501, the handle 506 is fixedly connected to the top of the locking pin 505, the cross section of the limit pin 502 is a T-shaped structure, and the handle 506 is a square-frame-shaped structure.

[0022] In specific use, press the limit pin 502 inward to make the insertion hole 504 translate and give way again, synchronously lift the handle 506 upward to drive the locking pin 505 to move upward so that the bottom end of the locking pin disengages from the insertion hole 504, then the protective cover 4 can be flipped upward to open. The sliding chute 507 and the guide post 508 cooperate to constrain the sliding track of the locking pin 505, preventing deviation and falling out.

[0023] A guide structure 3 is provided between the sliding table 2 and the cabinet 1. The guide structure 3 comprises sliding rods 301, inserting pins 302, a center block 303 and first springs 304. Both sides of the sliding table 2 are fixedly connected with the sliding rods 301 through two inserting pins 302 respectively, both sides of the top of the cabinet 1 are fixedly connected with the center block 303, the sliding rods 301 are in sliding connection with the center block 303 on the same side, the first springs 304 are fixedly connected between both sides of the center block 303 and the sliding table 2, and the two first springs 304 located on the same side are arranged symmetrically.

[0024] In specific use, push the sliding table 2 horizontally to make it slide smoothly in the center block 303 along the sliding rods 301 on both sides. The sliding rods 301 on both sides are fixed on the sliding table 2 through the inserting pins 302, which has high strength. The first springs 304 symmetrically arranged on both sides of the center block 303 provide elastic buffering and automatic return force, so the feeding feel is soft and automatic reset can be realized after releasing the hand.

[0025] A clamping structure 6 is installed on the top surface of the slide table 2. The clamping structure 6 includes a base 601 and an adjusting plate 602 slidably connected to the end of the base 601. The base 601 is slidably connected to the slide table 2. A guide block 612 is fixedly connected to the bottom surface of the base 601. The guide block 612 is slidably connected to a pre-set groove on the slide table 2. Multiple limiting holes 605 are provided on both sides of the base 601. Two limiting rods 603 are slidably connected to the end of the adjusting plate 602. A tension spring 604 is fixedly connected between the two limiting rods 603. The outer end of the limiting rod 603 engages with the adjacent limiting hole 605. A lead screw 608 is provided on the end of the base 601 opposite to the adjusting plate 602. The lead screw 608 is connected to the slide table. The slide plate 602 is rotatably connected to the base 601 and the lead screw 608. The end of the adjusting plate 602 is fixedly connected to the first clamping block 610. The slide plate 2 is fixedly connected to the second clamping block 611 near the first clamping block 610. The end of the lead screw 608 is fixedly connected to the handwheel 609. The adjusting plate 602 is slidably connected to the center of the two limit rods 603. The limit rods 603 are in the shape of an "L". Both sides of the driving block 606 are provided with inclined surfaces. The inclined surfaces on the sides of the driving block 606 are slidably engaged with the adjacent limit rods 603. The adjusting plate 602 is threadedly connected to the knob 607. The inner end of the knob 607 is rotatably connected to the driving block 606.

[0026] In practical use, the mold workpiece to be processed is placed between the first clamping block 610 and the second clamping block 611 on the top surface of the slide table 2. Under normal conditions, the two limiting rods 603 inside the adjusting plate 602 are kept in an inward contracted state by the tension of the tension spring 604. The outer ends of the limiting rods 603 are disengaged from the limiting holes 605 on the side of the base 601. At this time, the adjusting plate 602 can drive the first clamping block 610 to slide freely along the base 601, which facilitates quick and rough adjustment of the clamping distance between the first clamping block 610 and the second clamping block 611. Simply push the adjusting plate 602 along the base 601 to a position that is approximately suitable for the size of the workpiece, and then turn the knob 607 to drive the adjustment plate. Block 606 slides inward, and with the help of the inclined surfaces on both sides of the drive block 606, it pushes the two "L"-shaped limiting rods 603 to overcome the force of the tension spring 604 and open outward, so that the outer end of the limiting rod 603 is engaged in the limiting hole 605 of the corresponding position of the base 601, completing the coarse adjustment positioning. Then, the handwheel 609 is turned to drive the lead screw 608 to rotate. Through the threaded engagement between the lead screw 608 and the base 601, the base 601 is driven to slide along the groove preset on the top surface of the slide table 2 through the guide block 612. The guide block 612 constrains the movement trajectory to ensure that the feed is free of sway, and pushes the first clamping block 610 closer to the second clamping block 611, thereby accurately clamping the workpiece.

[0027] Two drive components 7 are fixedly connected inside the cabinet 1. Polishing wheel 8 and saw blade 9 are fixedly connected to the output shaft of the two drive components 7 respectively. The top of polishing wheel 8 and saw blade 9 both extend to the top surface of slide table 2.

[0028] In actual use, the two sets of drive components 7 in the cabinet 1 are started, which drive the polishing wheel 8 and the saw blade 9 to rotate respectively, and the workpiece is sent to the saw blade 9 and the polishing wheel 8 in sequence to complete the cutting and grinding process. The machine integrates two processes to improve processing efficiency.

[0029] Working principle: When opening the protective cover 4, simply press the limiting pin 502 inward to make it slide inward along the connecting block 501 and compress the second spring 503, so that the insertion hole 504 on the limiting pin 502 moves to the avoidance position, and then flip the protective cover 4 upward to open it around the hinge end. Next, the mold workpiece to be processed is placed between the first clamping block 610 and the second clamping block 611 on the top surface of the slide table 2. Under normal conditions, the two limiting rods 603 inside the adjusting plate 602 are kept in an inward contracted state by the tension of the tension spring 604. The outer ends of the limiting rods 603 are disengaged from the limiting holes 605 on the side of the base 601. At this time, the adjusting plate 602 can drive the first clamping block 610 to slide freely along the base 601, which facilitates quick and rough adjustment of the clamping distance between the first clamping block 610 and the second clamping block 611. Simply push the adjusting plate 602 along the base 601 to a position that matches the approximate size of the workpiece, and then turn the knob 607 to drive the driving block 6. 06 Slides inward, and with the help of the inclined surfaces on both sides of the drive block 606, pushes the two "L"-shaped limiting rods 603 to overcome the force of the tension spring 604 and open outward, so that the outer end of the limiting rod 603 is inserted into the corresponding limiting hole 605 of the base 601, completing the coarse adjustment positioning. Then, turn the handwheel 609 to drive the lead screw 608 to rotate. Through the threaded engagement between the lead screw 608 and the base 601, the base 601 is driven to slide along the groove preset on the top surface of the slide table 2 through the guide block 612. The guide block 612 constrains the motion trajectory to ensure that the feed is free of sway, and pushes the first clamping block 610 closer to the second clamping block 611, thereby accurately clamping the workpiece. After clamping, flip the protective cover 4 downwards. During the closing process, press the limiting pin 502 inwards first. Then, the locking pin 505 on the protective cover 4 passes through the insertion hole 504 on the limiting pin 502. After the protective cover 4 is fully closed, release the limiting pin 502. The second spring 503 rebounds and pushes the limiting pin 502 to reset outwards. The inner wall of the insertion hole 504 then presses against the rod of the locking pin 505. At the same time, the "L"-shaped protrusion at the bottom of the locking pin 505 touches the bottom surface of the limiting pin 502 after the limiting pin 502 is reset, forming an axial hook lock. The sliding groove 507 and the guide post 508 cooperate to constrain the sliding trajectory of the locking pin 505 to prevent it from deviating and coming off. At this time, the locking of the protective cover 4 after closing is achieved, which can effectively prevent the protective cover 4 from being accidentally opened during processing and avoid the safety hazard of flying debris. The two sets of drive components 7 (preferably a belt drive assembly consisting of a motor, pulley, belt, bearing housing and shaft) inside the start cabinet 1 drive the polishing wheel 8 and saw blade 9 to rotate, respectively, and horizontally push the slide table 2 so that it slides smoothly in the center block 303 along the two side slide rods 301. The two side slide rods 301 are fixed to the slide table 2 by the pins 302, which is very strong. The first springs 304 symmetrically arranged on both sides of the center block 303 provide elastic buffer and automatic return force. The feed feel is soft and it automatically resets after being released. The workpiece is sent to the saw blade 9 and polishing wheel 8 in sequence to complete the cutting and grinding process. The machine integrates two processes to improve the processing efficiency. After processing is completed, press the limit pin 502 inward to make the insertion hole 504 move horizontally again to avoid it. At the same time, lift the handle 506 upward to drive the locking pin 505 to move upward so that its bottom end is disengaged from the insertion hole 504. Then, flip it upward to open the protective cover 4. Turn the handwheel 609 in the opposite direction to release the workpiece and take it out.
