Description

Technical Field

[0001] This invention relates to the field of plastic mold cutting technology, specifically to a plastic mold cutting device. Background Technology

[0002] Plastic molds are used to process plastic raw materials into plastic products with specific shapes, sizes, and precision. After the plastic raw material is heated and softened, it is fitted into the mold cavity through injection molding, blow molding, or other methods. After cooling and solidification, it is demolded to obtain plastic products with uniform specifications. During the injection molding process of plastic molds, some excess material often remains on the sides of the plastic products, which needs to be removed using a cutting device.

[0003] Existing plastic mold cutting devices generate debris during the cutting process, including fine particles and larger chunks. The debris handling mechanisms of existing devices are relatively simple, mostly consisting of only a single dust extraction structure, which can only absorb some of the fine particles. Larger chunks tend to accumulate on the worktable, and the resulting mixed debris buildup makes subsequent cleaning and sorting difficult, increasing the workload for operators. Therefore, we propose a new plastic mold cutting device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a plastic mold cutting device that solves the problem of debris generated during the cutting process, including fine particles and larger chunks. Existing devices have relatively simple debris handling mechanisms, mostly consisting of a single dust collection structure that can only absorb some of the fine particles. Larger chunks tend to accumulate on the worktable, and the resulting mixed accumulation of debris makes subsequent cleaning and sorting difficult, increasing the maintenance workload for operators.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A plastic mold cutting device includes a housing, a fixed frame fixedly connected to the top of the housing, an adjusting block slidably connected to the inner wall of the fixed frame, a linear module fixedly connected to the top of the adjusting block, a connecting frame mounted on the slider of the linear module, a cutting machine mounted at one end of the connecting frame, a dust suction hood fixedly connected to the bottom of the connecting frame, and a dust suction pipe provided on the outside of the dust suction hood. The inner cavity of the housing is fixedly connected with multiple limiting rods in a linear array. A sliding frame is slidably sleeved on the outside of the limiting rods. An adjustment mechanism for driving the sliding frame to reciprocate is provided inside the housing. A filter plate is slidably connected to the inner wall of the sliding frame. A fixing mechanism for locking the position of the filter plate is provided inside the sliding frame.

[0006] In a preferred embodiment, a fixed base is fixedly connected to the top of the housing, a rotating shaft is rotatably connected inside the fixed base, a placement seat is fixedly connected to one end of the rotating shaft, the placement seat is rotatably connected to the fixed base, and a clamping assembly is provided on the top of the placement seat.

[0007] The technical effect of adopting the above-mentioned further solution is that the rotating shaft drives the placement seat to rotate, which facilitates the cutting operation on the other side of the plastic product.

[0008] In a preferred embodiment, a worm gear is fixedly sleeved on the outside of the rotating shaft, and a worm that works with the worm gear is rotatably connected inside the fixed seat via a bearing. A second motor is fixedly connected to the outer side of the fixed seat, and the output end of the second motor is fixedly connected to the worm.

[0009] The technical effect of adopting the above-mentioned further solution is that the second motor drives the worm wheel to rotate through the worm gear, and the worm wheel drives the rotating shaft to rotate, thereby driving the placement seat to rotate.

[0010] In a preferred embodiment, the clamping assembly includes a groove formed on the top of the placement seat, a convex block symmetrically slidably connected inside the groove, a bidirectional lead screw rotatably connected inside the placement seat, the convex block being threadedly connected to the bidirectional lead screw, and a handwheel being fixedly connected to one end of the bidirectional lead screw.

[0011] The technical effect of adopting the above-mentioned further solution is that the handwheel drives the bidirectional lead screw to rotate, thereby driving the two sets of convex blocks to slide along the slide groove, and the plastic product can be clamped and fixed by the two sets of convex blocks.

[0012] In a preferred embodiment, the fixed frame is provided with a moving component for moving the adjusting block. The moving component includes a lead screw rotatably connected inside the fixed frame. The adjusting block is threadedly connected to the lead screw. A first motor is fixedly connected to the outer side of the fixed frame. The output end of the first motor is fixedly connected to the lead screw. One end of the lead screw extends outside the fixed frame.

[0013] The technical effect of adopting the above-mentioned further solution is that the first motor drives the lead screw to rotate, thereby driving the adjusting block to move, which can perform a uniform cutting operation on the plastic product.

[0014] In a preferred embodiment, a first collection frame and a second collection frame are slidably connected inside the housing, and handles are fixedly connected to the outside of both the first collection frame and the outside of the second collection frame.

[0015] The technical advantage of adopting the above-mentioned further solution is that the setting of the first collection frame and the second collection frame facilitates the classification and collection of waste after screening.

[0016] In a preferred embodiment, the adjustment mechanism includes a drive shaft rotatably connected to the inner cavity of the housing via a bearing. The drive shaft is connected to a lead screw via a synchronous belt. Multiple eccentric wheels are fixedly connected to the outside of the drive shaft in a linear array. A spring is sleeved on the outside of the limiting rod and above the sliding frame.

[0017] The technical effect of adopting the above-mentioned further solution is as follows: the lead screw drives the synchronous wheel outside the transmission shaft to rotate through the synchronous wheel and synchronous belt on its outer side, thereby driving the transmission shaft to rotate. The transmission shaft drives the eccentric wheel to rotate, causing the eccentric wheel to press upward and drive the sliding frame to slide along the limit rod. The spring is compressed. When the eccentric wheel rotates downward, it no longer presses the sliding frame. Multiple sets of springs will drive the sliding frame to move and reset, thereby driving the sliding frame to reciprocate up and down.

[0018] In a preferred embodiment, the fixing mechanism includes a first sliding plate and a second sliding plate slidably connected to the inner cavity of the sliding frame. A plurality of plug-in posts are fixedly connected in a linear array to one side of the first sliding plate and the bottom of the second sliding plate. The plug-in posts are slidably connected to the sliding frame. A plurality of slots that cooperate with the plug-in posts are opened in a linear array inside the filter plate. The plug-in posts are movably inserted into the slots.

[0019] The technical effect of adopting the above-mentioned further solution is that the movement of the first sliding plate and the second sliding plate drives the insertion post to move, so that the insertion post moves into or out of the slot, which facilitates the quick installation and removal of the filter plate.

[0020] In a preferred embodiment, a support frame is symmetrically fixedly connected to the outside of the sliding frame, and an electric push rod is fixedly connected to one side of the support frame. The output end of the electric push rod is fixedly connected to a first sliding plate. Multiple cylinders are fixedly connected to the top of the first sliding plate in a linear array, and multiple connecting seats are fixedly connected to one side of the second sliding plate in a linear array. The connecting seats have inclined grooves inside that cooperate with the cylinders.

[0021] The technical effect of adopting the above-mentioned further solution is that the electric push rod drives the first sliding plate to move, and the first sliding plate drives the cylinder to move, so that the cylinder cooperates with the inclined groove, thereby squeezing and driving the connecting seat to slide when the cylinder moves.

[0022] This invention provides a plastic mold cutting device. Compared with the prior art, it has the following advantages: 1. This plastic mold cutting device, through the dust collection hood set under the cutting machine and in conjunction with the external dust collection equipment, can adsorb the fine waste generated during the cutting process, reducing the impact of waste scattering on the working environment and operators. The set filter plate can screen the waste, realize the classification and collection of waste, facilitate subsequent recycling and reuse, reduce resource waste, and reduce the workload of waste cleaning.

[0023] 2. This plastic mold cutting device has an adjustment mechanism that is linked to the lead screw via a synchronous belt. When the lead screw rotates, it drives the transmission shaft and eccentric wheel to rotate. With the reset action of the spring, the sliding frame and filter plate move up and down repeatedly, effectively preventing filter plate blockage caused by waste accumulation and ensuring the continuity of waste screening and collection. The fixed mechanism allows for quick disassembly and assembly of the filter plate without the need for special tools, greatly improving maintenance convenience and reducing maintenance downtime.

[0026] 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.

[0027] Please see Figures 1 to 12 The present invention provides a technical solution: A plastic mold cutting device includes a housing 1, a fixed frame 2 fixedly connected to the top of the housing 1, an adjusting block 21 slidably connected to the inner wall of the fixed frame 2, a linear module 3 fixedly connected to the top of the adjusting block 21, a connecting frame 31 mounted on the slider of the linear module 3, a cutting machine 33 mounted at one end of the connecting frame 31, and a dust collection hood 32 fixedly connected to the bottom of the connecting frame 31. A dust collection pipe is provided on the outside of the dust collection hood 32. The linear module 3 is moved by the adjusting block 21 to facilitate uniform cutting of plastic products. The linear module 3 can move the connecting frame 31, which in turn moves the cutting machine 33, facilitating position adjustment during cutting. The dust collection pipe is connected to an external dust collection device. The dust collection hood 32 can absorb and treat small particles of waste during cutting. like Figures 4 to 7 As shown, the inner cavity of the housing 1 is fixedly connected with multiple limiting rods 5 in a linear array. A sliding frame 6 is slidably sleeved on the outside of the limiting rods 5. An adjustment mechanism for driving the sliding frame 6 to reciprocate is provided inside the housing 1. A filter plate 13 is slidably connected to the inner wall of the sliding frame 6. A fixing mechanism for locking the position of the filter plate 13 is provided inside the sliding frame 6.

[0028] In this design, the movement of the sliding frame 6 can be limited vertically by setting multiple sets of limiting rods 5, so that the sliding frame 6 slides along the multiple sets of limiting rods 5 to prevent deviation. The adjustment mechanism can drive the sliding frame 6 to move up and down reciprocally, and the sliding frame 6 drives the filter plate 13 to move reciprocally to prevent the filter plate 13 from becoming clogged. The fixing mechanism can lock the position of the filter plate 13, which facilitates the installation and fixing of the filter plate 13.

[0029] like Figure 11 and Figure 12 As shown: In this scheme, a fixed base 4 is fixedly connected to the top of the housing 1. A rotating shaft 49 is rotatably connected inside the fixed base 4. A placement seat 41 is fixedly connected to one end of the rotating shaft 49. The placement seat 41 is rotatably connected to the fixed base 4. A clamping assembly is provided on the top of the placement seat 41. A worm gear 47 is fixedly sleeved on the outside of the rotating shaft 49. A worm 48 that works with the worm gear 47 is rotatably connected inside the fixed base 4 through a bearing. A second motor 42 is fixedly connected to the outer side of the fixed base 4. The output end of the second motor 42 is fixedly connected to the worm 48. The clamping assembly includes a sliding groove 45 opened on the top of the placement seat 41. A convex block 43 is symmetrically slidably connected inside the sliding groove 45. A bidirectional lead screw 46 is rotatably connected inside the placement seat 41. The convex block 43 is threadedly connected to the bidirectional lead screw 46. A handwheel 44 is fixedly connected to one end of the bidirectional lead screw 46.

[0030] In this solution, the plastic product to be cut is placed on top of the placement seat 41. The handwheel 44 is turned, which drives the bidirectional lead screw 46 to rotate, thereby causing the two sets of convex blocks 43 to slide along the slide groove 45. The two sets of convex blocks 43 can clamp and fix the plastic product. When it is necessary to cut the other side of the plastic product, the second motor 42 is started. The second motor 42 drives the worm wheel 47 to rotate through the worm gear 48. The worm wheel 47 drives the rotating shaft 49 to rotate, thereby driving the placement seat 41 to rotate, which facilitates the cutting operation on the other side of the plastic product.

[0031] like Figure 3 and Figure 5 As shown: In this solution, the fixed frame 2 is equipped with a moving component for moving the adjusting block 21. The moving component includes a lead screw 23 rotatably connected inside the fixed frame 2. The adjusting block 21 is threadedly connected to the lead screw 23. A first motor 22 is fixedly connected to the outer side of the fixed frame 2. The output end of the first motor 22 is fixedly connected to the lead screw 23. One end of the lead screw 23 extends outside the fixed frame 2. In this solution, the first motor 22 drives the lead screw 23 to rotate, thereby moving the adjusting block 21, which can perform a uniform cutting operation on the plastic product.

[0032] Inside the housing 1, a first collection frame 11 and a second collection frame 12 are slidably connected in sequence. Handles are fixedly connected to the outside of both the first collection frame 11 and the second collection frame 12. The arrangement of the first collection frame 11 and the second collection frame 12 facilitates the classification and collection of waste after screening.

[0033] like Figure 4 and Figure 5 As shown: In this scheme, the adjustment mechanism includes a drive shaft 53 that is rotatably connected to the inner cavity of the housing 1 via a bearing. The drive shaft 53 is connected to the lead screw 23 via a synchronous belt 24. Multiple eccentric wheels 52 are fixedly connected to the outside of the drive shaft 53 in a linear array. A spring 51 is sleeved on the outside of the limiting rod 5 and above the sliding frame 6.

[0034] In this scheme, during the rotation of the lead screw 23, the lead screw 23 will drive the synchronous pulley outside the transmission shaft 53 to rotate through the synchronous pulley and synchronous belt 24 on its outer side, thereby driving the transmission shaft 53 to rotate. The transmission shaft 53 drives the eccentric wheel 52 to rotate, causing the eccentric wheel 52 to press upward and drive the sliding frame 6 to slide along the limit rod 5. The spring 51 is compressed. When the eccentric wheel 52 rotates downward, it no longer presses the sliding frame 6. Multiple sets of springs 51 will drive the sliding frame 6 to move and reset, thereby driving the sliding frame 6 to reciprocate up and down. The sliding frame 6 drives the filter plate 13 to reciprocate, preventing the filter plate 13 from becoming clogged.

[0035] like Figures 8 to 10 As shown: In this scheme, the fixing mechanism includes a first sliding plate 63 and a second sliding plate 65 slidably connected to the inner cavity of the sliding frame 6. The inner cavity space of the sliding frame restricts the second sliding plate 65 to move only up and down, not horizontally. Multiple insertion posts 66 are fixedly connected in a linear array to one side of the first sliding plate 63 and the bottom of the second sliding plate 65. The insertion posts 66 are slidably connected to the sliding frame 6. Multiple slots 14, which cooperate with the insertion posts 66, are linearly arranged inside the filter plate 13. The insertion posts 66 are movably inserted into the slots 14. A support frame 61 is symmetrically fixedly connected to the outside of the sliding frame 6. An electric push rod 62 is fixedly connected to one side of the support frame 61. The output end of the electric push rod 62 is fixedly connected to the first sliding plate 63. Multiple cylinders 68 are fixedly connected in a linear array to the top of the first sliding plate 63. Multiple connecting seats 64 are fixedly connected in a linear array to one side of the second sliding plate 65. An inclined groove 67, which cooperates with the cylinders 68, is opened inside the connecting seat 64.

[0036] In this scheme, two sets of electric push rods 62 can be controlled to move synchronously by an external push rod synchronous controller. When the filter plate 13 is installed, the cylinder 68 is located at the top of the inclined groove 67. When the filter plate 13 needs to be disassembled, the inspection plate outside the housing 1 is opened, and the electric push rod 62 is started. The electric push rod 62 drives the first sliding plate 63 to move away from the filter plate 13. The first sliding plate 63 drives the cylinder 68 to move, so that the cylinder 68 cooperates with the inclined groove 67. Thus, when the cylinder 68 moves, it squeezes and drives the connecting seat 64 to move upward. The connecting seat 64 drives the second sliding plate 65 to move upward. The movement of the first sliding plate 63 and the second sliding plate 65 will drive the insertion post 66 to move and disengage from the slot 14, so that the filter plate 13 can be taken out. When the filter plate 13 needs to be installed, the cylinder 68 is located at the bottom of the inclined groove 67. Push the filter plate 13 into the sliding frame 6, start the electric push rod 62, and the electric push rod 62 drives the first sliding plate 63 to move closer to the filter plate 13. The first sliding plate 63 drives the cylinder 68 to move, so that the cylinder 68 cooperates with the inclined groove 67. As the cylinder 68 moves, it squeezes and drives the connecting seat 64 to move downward. The connecting seat 64 drives the second sliding plate 65 to move downward. The movement of the first sliding plate 63 and the second sliding plate 65 will drive the insertion post 66 to move into the slot 14, thereby locking the position of the filter plate 13 and completing the installation.

[0037] Working principle: When in use, place the plastic product to be cut on the top of the placement seat 41, turn the handwheel 44, the handwheel 44 drives the bidirectional lead screw 46 to rotate, thereby causing the two sets of convex blocks 43 to slide along the slide groove 45, and the plastic product can be clamped and fixed by the two sets of convex blocks 43. The linear module 3 can move the connecting frame 31, which in turn moves the cutting machine 33, thereby adjusting the cutting position. After adjustment, the cutting machine 33 can be used for cutting. The first motor 22 is started, which drives the lead screw 23 to rotate, thereby moving the adjusting block 21. This allows for uniform cutting of plastic products. The dust collection pipe is connected to an external dust collection device. The dust collection hood 32 can absorb small particles of debris during cutting, while larger particles fall into the interior of the housing 1. The filter plate 13 can screen larger particles of debris, making it easier to classify and collect them. During the rotation of the lead screw 23, the lead screw 23 will drive the synchronous wheel outside the transmission shaft 53 to rotate through the synchronous wheel and synchronous belt 24 on its outer side, thereby driving the transmission shaft 53 to rotate. The transmission shaft 53 drives the eccentric wheel 52 to rotate, causing the eccentric wheel 52 to press upward and drive the sliding frame 6 to slide along the limit rod 5. The spring 51 is compressed. When the eccentric wheel 52 rotates downward, it no longer presses the sliding frame 6. Multiple sets of springs 51 will drive the sliding frame 6 to move and reset, thereby driving the sliding frame 6 to reciprocate up and down. The sliding frame 6 drives the filter plate 13 to reciprocate, preventing the filter plate 13 from becoming blocked, and can carry larger particles of debris into the first collection frame 11. The screened debris enters the second collection frame 12 for classified collection. When the filter plate 13 is installed, the cylinder 68 is located at the top of the inclined groove 67. When the filter plate 13 needs to be disassembled, open the inspection plate outside the housing 1, start the electric push rod 62. The electric push rod 62 drives the first sliding plate 63 to move away from the filter plate 13. The first sliding plate 63 drives the cylinder 68 to move, so that the cylinder 68 cooperates with the inclined groove 67. As the cylinder 68 moves, it squeezes and drives the connecting seat 64 to move upward. The connecting seat 64 drives the second sliding plate 65 to move upward. The movement of the first sliding plate 63 and the second sliding plate 65 will drive the insertion post 66 to move and disengage from the slot 14, so that the filter plate 13 can be taken out. When the filter plate 13 needs to be installed, the cylinder 68 is located at the bottom of the inclined groove 67. Push the filter plate 13 into the sliding frame 6, start the electric push rod 62, and the electric push rod 62 drives the first sliding plate 63 to move closer to the filter plate 13. The first sliding plate 63 drives the cylinder 68 to move, so that the cylinder 68 cooperates with the inclined groove 67. As the cylinder 68 moves, it squeezes and drives the connecting seat 64 to move downward. The connecting seat 64 drives the second sliding plate 65 to move downward. The movement of the first sliding plate 63 and the second sliding plate 65 will drive the insertion post 66 to move into the slot 14, thereby locking the position of the filter plate 13 and completing the installation.
