Description

Technical Field

[0001] The present application relates to the technical field of dust removal in mold production, and in particular to a dust removal system and method for plastic mold production. Background Art

[0002] Plastic molds are tools used in the plastic processing industry to match plastic molding machines and give plastic products complete configurations and precise dimensions. Due to the wide variety of plastics and processing methods, and the varying complexity of the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse. Plastic molds undergo multiple procedures during production and processing, among which polishing is a very important process in the mold making process. With the increasing application of plastic products, the requirements for the appearance quality of plastic products are also getting higher and higher, so the surface polishing quality of the plastic mold cavity must also be improved accordingly, especially for molds with mirror and high-gloss surfaces, which require higher surface roughness of the mold, and therefore higher requirements for polishing. Polishing not only increases the beauty of the workpiece, but also improves the corrosion resistance and wear resistance of the material surface, and can also facilitate subsequent injection molding processing, such as making plastic products easy to demold and reducing the production injection molding cycle. Mould polishing generally uses oil stone, sandpaper, polishing paste, wool wheel, etc. to grind the cavity surface of the mould. During the grinding process, particles of dust will be generated. If it is not cleaned in time, it will seriously affect the overall grinding and polishing quality of the mould, and it is very likely that the produced mould will not meet the requirements and cannot be used.

[0003] For example, in the existing Chinese patent with the publication number CN218111415U, a surface dust removal device for plastic mold production and processing is disclosed, which includes a box body, two pulleys and four sprockets, a motor is fixedly installed on the top right side of the box body, a rotating rod is fixedly installed on the output shaft of the motor, a plurality of long bristles are fixedly installed on one end of the rotating rod, a plurality of cylinders are rotatably installed between the front and rear inner walls of the box body, and the left inner wall of the box body, the lower half of the middle baffle and the bottom inner wall constitute a water storage tank. Through the above-mentioned existing technology, the motor and the water pump are started, the water in the water storage tank of the water pump is pumped out, and the mold is cleaned through the nozzle, the motor drives the rotating rod to rotate, and the long bristles fixed on the rotating rod are used to remove dust and brush the upper half of the mold, and under the cooperation of the eccentric wheel and the reset spring, the long plate and the friction plate perform horizontal reciprocating motion, and the bottom of the mold is dusted by the bristles.

[0004] However, the above prior art has the following technical defects:

[0005] The above-mentioned prior art is to place the mold into a box, and separately remove the dust and brush the dust remaining on the surface of the mold after the overall polishing and grinding is completed. While the mold is being polished and grinded, the particle dust generated needs to be cleaned to prevent the particle dust generated by the grinding from remaining on the mold surface and affecting the subsequent grinding of other parts, thereby resulting in poor overall grinding quality that does not meet the specification requirements and cannot be used.

[0006] Based on this, on the basis of the existing surface dust removal device for plastic mold production and processing, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

The lower and upper actuators can continuously vacuum and remove the dust generated by polishing to prevent dust from accumulating and adhering to the plastic mold.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] By rotating the adjusting crank, the bidirectional screw can be driven to rotate under the action of the mutual meshing of the regulating gear and the transmission gear. The bidirectional screw cooperates with the threaded perforation on the trapezoidal slider so that when the bidirectional screw rotates, the two trapezoidal sliders can be driven to move closer to or away from each other. The synchronous supporting vertical rods and the elongated clamping blocks installed on the upper ends of the supporting vertical rods follow the trapezoidal sliders to move closer to or away from each other, thereby achieving the effect of clamping the plastic mold through the elongated clamping blocks by rotating the adjusting crank.

[0027] When the adjustment handle is rotated to the position of the corresponding L-shaped limit rod, the convex limit rod contacts the L-shaped limit rod, and the adjustment handle cannot be rotated further, that is, it is rotated to the specified angle, and the locking tooth block is released. Under the action of the reset spring, the locking tooth block limits the locking gear again, thereby achieving the effect of locking the rotation angle of the plastic mold.

[0028] After adjusting the grinding position angle of the plastic mold, the U-shaped locking rod is first pulled upward before grinding the plastic mold, so that the U-shaped locking rod no longer limits the concave blocks on both sides, and the lower rubber block can be driven to slide in the direction of the rectangular iron absorption block under the mutual attraction of the square iron absorption block and the rectangular iron absorption block, and the synchronous sliding of the lower rack drives the upper rack to slide synchronously in the opposite direction under the action of the action gear, and drives the upper rubber block to slide in the upper rectangular box through the first L rod, and under the action of the pull-back spring and the rectangular iron absorption block, negative pressure is continuously formed in the upper rectangular box and the lower rectangular box, so that the dust formed by grinding the plastic mold in the dust removal cover is sucked into the upper rectangular box and the lower rectangular box through the dust suction ring groove and the dust suction pipe, and then continuously discharged from the upper rectangular box and the lower rectangular box, while some larger granular dust generated during grinding is blocked by the blocking mesh frame and falls into the collection box, so as to achieve the effect of synchronously sucking and removing the dust generated when grinding the plastic mold.

When the other limiting groove 281 of the regulating rod 28 extends out of the control box 27, push the arc-lifting block 32 downwards to drive the limiting disc 31 to slide downwards and reset to be stuck on the other limiting groove 281. At this time, the regulating gear 29 and the transmission gear 291 are no longer meshed, and the drive ring The teeth 52 enter the inner gear shaft 51 and mesh with multiple tooth blocks on the inner wall of the inner gear shaft 51. At this time, the rotation of the regulating rod 28 can drive the inner gear shaft 51 to rotate without driving the bidirectional screw 23 to rotate; under the action of the transmission belt 55, the inner gear shaft 51 rotates, and the transmission rod 53 rotates synchronously, which can drive one of the angle cylinders 24 and the elongated clamping block 25 to rotate through the square connecting rod 54, so as to achieve the effect that rotating the regulating crank 292 can drive the plastic mold to rotate; the locker 6 can lock the transmission rod 53 to lock the angle of the plastic mold.

The bottom wall of the tail slide groove 571 is fixedly connected; the reset spring 63 always has the driving force to drive the dovetail slider 64 to slide upward, that is, under normal circumstances, the locking tooth block 62 is always engaged with the locking gear 61 and the transmission rod 53 cannot rotate. When it is necessary to rotate the adjustment crank 292 to drive the plastic mold to adjust the angle, it is necessary to press the locking tooth block 62 downward first, so that the locking gear 61 and the transmission rod 53 are in a rotatable state. After the angle rotation adjustment is completed, release the locking tooth block 62. Under the action of the reset spring 63, the locking tooth block 62 slides upward and resets to re-engage the locking gear 61, and the locking gear 61 and the transmission rod 53 are in a state where they cannot rotate again.

When negative pressure is generated in the inner cavity of the lower rectangular box 41 and the upper rectangular box 42, the dust generated during the polishing of the plastic mold can be sucked into the lower rectangular box 41 and the upper rectangular box 42 through the one-way air inlet valve 72 and the dust suction pipe 75, and the dust gas in the lower rectangular box 41 and the upper rectangular box 42 can be discharged through the one-way exhaust valve 71; the upper actuator 8 and the lower actuator 9 are respectively arranged on the upper rectangular box 42 and the lower rectangular box 41.

[0057] Reference Fig.12 As shown, it is a schematic diagram of the structure of the upper operating mechanism 8 in this embodiment. The upper operating mechanism 8 includes an upper rubber block 81, a first L-rod 82, concave blocks 83 on both sides, a rectangular bottom plate 84 and a U-shaped locking rod 85; the upper rubber block 81 is slidably arranged in the upper rectangular box 42 through a pull-back spring 86, and the pull-back spring 86 always has a driving force to pull the upper rubber block 81 to the side of the upper rectangular box 42 where the vent 421 is opened; the first L-rod 82 is inserted into the upper rectangular box 42, and the insertion end is fixedly connected to the upper rubber block 81, and the other end is fixedly connected to the upper rack 43. The upper rectangular box 42 is provided with an insertion through hole 422 for the first L-rod 82 to be inserted and installed, and the concave blocks 83 on both sides are fixedly installed On the first L-rod 82 outside the upper rectangular box 42, the two side recessed blocks 83 are in the shape of an "I" with recesses on both sides; the rectangular bottom plate 84 is fixedly installed on the upper side of the upper rectangular box 42, and the U-shaped locking rod 85 is inserted and slidably arranged on the rectangular bottom plate 84, and a locking hole 841 is penetrated on the rectangular bottom plate 84 for the U-shaped locking rod 85 to be inserted and slid; when the U-shaped locking rod 85 is inserted downward into the recesses on both sides of the recessed blocks 83 on both sides, the first L-rod 82 can limit the upper rack 43. At this time, even if the lower rack 44 has a driving force, it cannot slide, that is, when the U-shaped locking rod 85 is inserted into the recesses on both sides of the recessed blocks 83 on both sides, it will also limit and lock the lower rack 44.

[0058] Reference Fig.13 and Fig.14 As shown, since it is necessary to cooperate with the upper operating device 8 to continuously form negative pressure in the upper rectangular box 42 and the lower rectangular box 41, the lower operating device 9 includes a lower rubber block 91, a second L rod 92, a square magnet block 93, a linkage slide bar 94, a rectangular magnet block 95, a contraction spring 96 and a trapezoidal drive block 97; the lower rubber block 91 is slidably arranged in the lower rectangular box 41, the second L rod 92 is inserted in the lower rectangular box 41, and the insertion end is fixedly connected to the lower rubber block 91, and the other end is fixedly connected to the lower rack 44, the lower rectangular box 41 is provided with an insertion hole 412 for the second L rod 92 to be inserted and installed, the square magnet block 93 is symmetrically fixedly installed on one end of the lower rubber block 91 away from the second L rod 92, the linkage slide bar 94 is slidably installed in the inner bottom wall of the lower rectangular box 41, and the lower rectangular box 41 is provided with a rectangular slide groove 413 for the linkage slide bar 94 to be installed; the two ends of the linkage slide bar 94 are upwardly convex, and can slide left and right in the rectangular slide groove 413 under force.

[0059] The rectangular magnetic block 95 is arranged in the lower rectangular box 41 by sliding up and down through two round short rods 98. The rectangular magnetic block 95 and the square magnetic block 93 have mutual attraction, and this attraction is greater than the driving force of the pull-back spring 86 on the upper rubber block 81; the rectangular magnetic block 95 is penetrated by a round rod hole 951 adapted to the round short rod 98, and a square groove 414 connected to the rectangular slide 413 for the installation of the rectangular magnetic block 95 is provided on the inner bottom wall of the lower rectangular box 41 near the air vent 421. When the rectangular magnetic block 95 is driven to extend out of the square groove 414, the mutual attraction between the rectangular magnetic block 95 and the square magnetic block 93 is formed, and the lower rubber block 91 will slide in the direction of the square groove 414, and synchronously under the action of the lower rack 44 and the upper rack 43, the upper rubber block 81 in the upper rectangular box 42 moves in the opposite direction to the sliding direction of the lower rubber block 91. When the upper rubber block 91 slides toward the square groove 414, the gas in the upper rectangular box 42 can be discharged through the one-way exhaust valve 71. Similarly, when the lower rubber block 91 slides toward the square groove 414, a negative pressure will be formed in the upper part of the lower rectangular box 41, and the dust generated by grinding can be sucked into the lower rectangular box 41 through the dust suction pipe 75; the contraction spring 96 is sleeved on the short round rod 98, one end of which is fixedly connected to the lower side of the rectangular magnetic block 95, and the other end is fixedly connected to the bottom wall of the square groove 414. The contraction spring 96 always has a driving force to pull the rectangular magnetic block 95 downward into the square groove 414. Without the action of external force, the rectangular magnetic block 95 is always in the square groove 414 and will not form an attraction driving force on the square magnetic block 93; the trapezoidal drive block 97 is arranged in the square groove 414 and is fixedly connected to the linkage slide bar 94 through the folding block 99.

[0060] In the initial state, the rubber block 91 abuts against the linkage slide bar 94 and is located away from the square groove 414. When the lower rubber block 91 abuts against the linkage slide bar 94, it can drive the linkage slide bar 94 to slide in a direction away from the square groove 414. At this time, under the action of the folding block 99, the trapezoidal drive block 97 can be driven to slide. The initial position of the trapezoidal drive block 97 is at the square groove 414 between the rectangular magnet block 95 and the vent 421. The inclined surface of the trapezoidal drive block 97 abuts against the rectangular magnet block 95, driving the rectangular magnet block 95 to slide upward and extend out of the square groove 414. 4. When the lower rubber block 91 abuts against the linkage slide bar 94 and is at the maximum travel distance away from the square groove 414, the upper plane of the trapezoidal drive block 97 abuts against the lower side of the rectangular magnetic block 95. At this time, the rectangular magnetic block 95 cannot slide down even with the action of the contraction spring 96. The rectangular magnetic block 95 extends out of the square groove 414 to form an attraction for the square magnetic block 93, and the lower rubber block 91 slides toward the square groove 414. However, since the U-shaped locking rod 85 is stuck in the concave blocks 83 on both sides, the upper rack 43 and the lower rack 44 cannot move.

[0061] When the rotation angle of the plastic mold is adjusted for grinding, the U-shaped locking rod 85 is pulled out upward, and the lower rubber block 91 slides in the direction of the square groove 414. Since the attraction of the rectangular magnetic block 95 to the square magnetic block 93 is greater than the driving force of the pull-back spring 86 on the upper rubber block 81, the upper rubber block 81 will slide in the opposite direction of the lower rubber block 91, that is, the pull-back spring 86 is stretched, and when the lower rubber block 91 is about to reach the square groove 414, it will contact with the other protruding end of the linkage slide rod 94 to drive the linkage slide rod 94 to slide in the direction of the square groove 414, and the trapezoidal drive block 97 is driven to withdraw from under the rectangular magnetic block 95 under the action of the folding block 99, and no longer contact the rectangular The magnetic block 95, at this moment, the rectangular magnetic block 95 slides downward into the square groove 414 under the action of the contraction spring 96, and then the attraction of the rectangular magnetic block 95 to the square magnetic block 93 disappears, and the return spring 86 pulls the upper rubber block 81 to slide back and reset. Similarly, the lower rubber block 91 at this time will slide in the opposite direction of the upper rubber block 81, that is, the lower rubber block 91 slides away from the square groove 414, and the lower rubber block 91 again resists the other end protrusion of the linkage slide rod 94 to drive the linkage slide rod 94 to slide, and the trapezoidal drive block 97 will drive the rectangular magnetic block 95 to slide up and extend out of the square groove 414, and the rectangular magnetic block 95 will form an attraction to the square magnetic block 93 again.

[0062] In this reciprocating manner, negative pressure can be alternately formed in the lower rectangular box 41 and the upper rectangular box 42, and the dust generated during grinding is continuously sucked into the lower rectangular box 41 and the upper rectangular box 42 through the dust suction pipe 75 and the dust suction ring groove 132 and continuously discharged, so that the dust generated during the polishing of the plastic mold can be timely removed and cleaned, preventing the dust from adhering and accumulating on the surface of the plastic mold and affecting the subsequent grinding of other parts, thereby avoiding the polished plastic mold from being unqualified in size and unusable.

[0063] Reference Fig.15 As shown, on the other hand, the present application also discloses a dust removal method for plastic mold production, and the dust removal method is as follows:

[0064] The first step is to fix the mold: put the plastic mold to be polished into the dust cover 13, turn the adjustment crank 292 to drive the bidirectional screw 23 to rotate through the meshing action of the control gear 29 and the transmission gear 291, so as to drive the two elongated clamping blocks 25 to approach each other to clamp and fix the plastic mold;

[0065] The second step is drive adjustment: after clamping and fixing the plastic mold, pull the arc-lifting block 32 upward to drive the limit disc 31 to slide upward, pull the adjustment crank 292 outward to drive the regulating rod 28 to move outward, push the arc-lifting block 32 downward to make the limit disc 31 stuck on another limit groove 281, at this time, the driving ring gear 52 enters the inner gear shaft 51, and the regulating gear 29 and the transmission gear 291 are separated and no longer meshed, so as to achieve the purpose of changing the drive;

[0066] Step 3: Adjust the angle: rotate the angle of the plastic mold according to actual needs, push the L-shaped limit rod 33 at the corresponding position to extend, push the convex support rod 34 to slide toward the limit disc 31, press the locking tooth block 62 and rotate the adjustment crank 292 to drive the transmission round rod 53 and the square connecting rod 54 to rotate under the action of the transmission belt 55, so as to achieve the purpose of adjusting the angle;

[0067] The fourth step is to vacuum and remove dust: after adjusting the best angle for polishing, pull the U-shaped lock rod 85 upwards, and the lower actuator 9 and the upper actuator 8 can continuously vacuum and remove the dust generated by polishing to prevent dust from accumulating and adhering to the plastic mold.

[0068] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.

A method for removing dust from plastic mold production, characterized in that: The dust removal system for plastic mold production comprises the following method: The first step is to fix the mold: put the plastic mold to be polished into the dust cover (13), rotate the adjustment crank (292) to drive the bidirectional screw (23) to rotate through the meshing action of the control gear (29) and the transmission gear (291), so as to drive the two elongated clamping blocks (25) to approach each other and clamp the plastic mold; The second step is drive adjustment: after clamping and fixing the plastic mold, pull the arc lifting block (32) upward to drive the limit disc (31) to slide upward, pull the adjustment crank (292) outward to drive the regulating rod (28) to move outward, push the arc lifting block (32) downward to make the limit disc (31) stuck on another limit groove (281), at this time, the driving ring gear (52) enters the inner gear shaft (51), and the regulating gear (29) and the transmission gear (291) are separated and no longer meshed, so as to achieve the purpose of changing the drive; The third step is to adjust the angle: according to the actual needs, the angle of the plastic mold is rotated, the L-shaped limit rod (33) at the corresponding position is pushed out, the convex support rod (34) is pushed to slide in the direction of the limit disc (31), the locking tooth block (62) is pressed, and the adjustment crank (292) is rotated to drive the transmission round rod (53) and the square connecting rod (54) to rotate under the action of the transmission belt (55), so as to achieve the purpose of adjusting the angle; The fourth step is to vacuum and remove dust: after adjusting the best angle for polishing, pull the U-shaped lock rod (85) upwards, and the lower operating device (9) and the upper operating device (8) can continuously vacuum and remove the dust generated by polishing to prevent dust from accumulating and adhering to the plastic mold.
