Description

Technical Field

[0001] This invention belongs to the technical field of vertical injection molding machines, and specifically relates to a vertical injection molding machine with a rapid waste discharge structure. Background Technology

[0002] Vertical injection molding machines are widely used in precision injection molding fields such as insert molding, electronic components, and wire plugs. During the injection molding process, after the mold opens and closes, residual overflow, broken sprues, and carbon slag will appear on the surfaces and around the upper and lower molds. If these are not cleaned in time, they will not only affect the quality of subsequent injection molding, but may also lead to improper mold closure and product defects.

[0003] Currently, most vertical injection molding machines use air guns to blow away residual waste after mold opening. This method has several drawbacks. First, the blowing force of the air gun is difficult to control evenly, causing the waste to scatter after being blown away from the mold and fail to collect in the designated area. Even if the waste is temporarily blown away from the mold surface, preventing direct interference with mold closing, the waste scattered around the equipment or on the ground still needs to be collected by workers, increasing manual intervention and impacting processing efficiency.

[0004] Secondly, the waste removed by air gun cleaning is usually a mixture of sizes, including both small flash and larger sprue heads. Most existing injection molding machines only have simple material collection functions, and can only collect waste of different sizes and then transfer it to an external crusher for centralized crushing. Dust and impurities are easily mixed in during intermediate transfer and stacking, and direct crushing of mixed materials of different sizes can easily result in uneven particle size. When the particles are recycled and mixed, the feeding is unstable, which affects the plasticization uniformity and finished product quality of injection molding. The waste recycling process is cumbersome and has a low degree of automation, making it difficult to adapt to the needs of efficient continuous injection molding production. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical injection molding machine with a rapid waste discharge structure. Its advantages are that it can clean and collect the waste on the injection mold, while screening out larger waste particles, crushing them separately, and then discharging them together with smaller waste particles for collection.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a vertical injection molding machine with a rapid waste discharge structure, comprising a base, a support frame bolted to one side of the top of the base, a first cylinder bolted to both sides of the top of the support frame, a sliding plate bolted to the output end of the first cylinder, an upper mold bolted to the bottom of the sliding plate, a lower mold adapted to the upper mold bolted to the side of the top of the base near the sliding plate, a glue injection device bolted to the top of the sliding plate, a cleaning mechanism for use with the lower mold, and a chip removal mechanism for use with the cleaning mechanism, which is provided at the bottom of the inner cavity of the base.

[0007] The present invention is further configured such that the cleaning mechanism includes a second cylinder bolted to one side of the same base, a U-shaped plate bolted to the output end of the second cylinder, a sliding frame bolted to the top of the U-shaped plate and slidably connected to the same base, and a brush for use with the lower mold bolted to the top end of the sliding frame away from the second cylinder.

[0008] The above technical solution involves activating the cleaning mechanism to remove residual waste from the top of the lower mold, allowing the waste to fall into the interior of the platform for easy and unified collection.

[0009] The present invention is further configured such that the bottom of the U-shaped plate is bolted to a first linear rack that is slidably connected to the base, the bottom of the first linear rack being engaged with a gear that is rotatably connected to the base on the side away from the second cylinder, the bottom of the gear being engaged with a second linear rack on the side away from the first linear rack, and a pusher plate that is slidably connected to the base is welded to the end of the second linear rack away from the gear, and a guide groove for use with a brush is provided on the top of the base near the pusher plate.

[0010] The above technical solution is adopted: by driving the brush to clean the waste material remaining on the top of the lower mold, the pusher plate is simultaneously retracted into the base and the screening screen is exposed, so that the waste material cleaned by the brush on the top of the lower mold can slide down to the top of the screening screen through the guide chute, instead of falling onto the top of the pusher plate.

[0011] The invention is further configured such that the chip removal mechanism includes a collection trough located in the inner cavity of the platform at the end of the pusher plate away from the guide chute; a first motor bolted to the platform is provided at the bottom of the second cylinder; a discharge auger is rotatably connected to the bottom of the inner cavity of the collection trough; the end of the discharge auger away from the collection trough is bolted to the output end of the first motor; a shaking frame is slidably connected to the bottom of the pusher plate inside the platform; a screening screen is bolted to the top of the shaking frame; return springs are installed at both ends of the shaking frame through spring fixing parts; and a chip removal trough communicating with the bottom of the inner cavity of the collection trough is provided inside the platform at the bottom of the screening screen.

[0012] The above technical solution involves using a chip removal mechanism to screen the waste material that falls into the platform, thereby separating waste materials of different sizes and enabling the separate crushing of large waste particles.

[0013] The invention is further configured such that a rotating rod is provided through the interior of the shaking frame, the rotating rod is rotatably connected to the interior of the base, and a synchronous wheel is fixedly sleeved on the end of the rotating rod and the end of the discharge auger near the first motor. A synchronous belt is drivenly sleeved on the surface of the two synchronous wheels. An elliptical groove is opened inside the shaking frame, and a rocking rod that is slidably connected to the elliptical groove is fixedly sleeved inside the rotating rod.

[0014] The above technical solution involves driving the screening screen to oscillate back and forth, thereby screening out small waste particles from the top, while large waste particles remain at the top of the screening screen.

[0015] The present invention is further configured such that two crushing rollers symmetrically arranged at the bottom of the inner cavity of the collection tank are rotatably connected to the same platform. A second motor is bolted to one end of the platform near the crushing rollers. The output end of the second motor is bolted to one end of one of the crushing rollers. The ends of the two crushing rollers away from the second motor are bolted to mutually meshing circular gears.

[0016] The above technical solution involves turning on the second motor to drive two crushing rollers, which mesh with each other using two circular gears. This allows the two crushing rollers to rotate synchronously in opposite directions, thereby crushing large particles of waste falling into the collection tank separately.

[0017] The invention is further configured such that, symmetrical guide plates are bolted to the base at the top of the two crushing rollers in the inner cavity of the collection tank, a scraper is slidably connected to the bottom of the guide plates, and a positioning rod is threadedly connected to one side of the bottom of the guide plates and slidably connected to the scraper. A compression spring that works with the scraper is fitted on the outer surface of the positioning rod through a spring fixing component.

[0018] The above technical solution involves using a compression spring to make the scraper slide back and forth at the bottom of the guide plate, so that the bottom of the scraper can remain in contact with the top of the crushing roller, scraping off the plastic waste remaining on the top of the crushing roller and preventing the waste from adhering to the surface of the crushing roller and affecting the subsequent crushing effect.

[0019] The invention is further configured such that a positioning column, which is slidably connected to the sliding plate, is bolted to the side of the top of the pedestal near the support frame.

[0020] The above technical solution is used to guide and position the upper mold as it slides up and down on the top of the lower mold during opening and closing.

[0021] The present invention is further configured such that both ends of the base near the return spring are bolted to a detachable housing, and the end of the return spring away from the shaking frame is installed inside the detachable housing through a spring fixing member.

[0022] By adopting the above technical solution, the detachable housing can be removed from both sides of the platform, thereby replacing the internal reset springs that lack sufficient elasticity and ensuring the screening effect.

[0023] The present invention is further configured such that the platform is provided with a discharge port on the side of the bottom of the first motor, which is connected to the collection tank and the chip removal tank respectively.

[0024] The above technical solution allows small waste particles and crushed large waste particles to be conveyed by a discharge auger and discharged uniformly from the inside of the discharge port.

[0025] In summary, the present invention has the following beneficial effects: 1. By activating the cleaning mechanism, the waste material remaining on the top of the lower mold is swept away, allowing the waste material to fall into the interior of the platform for easy collection; at the same time, the chip removal mechanism is activated to screen the waste material falling into the platform, thereby separating waste material of different sizes. 2. By screening out larger waste particles, waste particles of different sizes are discharged through two different channels. The larger waste particles are crushed separately and then discharged together with the smaller particles, which facilitates the subsequent unified collection by the staff and improves the efficiency and convenience of waste recycling.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9A vertical injection molding machine with a rapid waste discharge structure includes a base 1. A support frame 2 is bolted to one side of the top of the base 1. First cylinders 3 are bolted to both sides of the top of the support frame 2. A sliding plate 4 is bolted to the output end of the first cylinder 3. An upper mold 5 is bolted to the bottom of the sliding plate 4. A lower mold 6, compatible with the upper mold 5, is bolted to the side of the top of the base 1 near the sliding plate 4. An injection device 9 is bolted to the top of the sliding plate 4. The injection device 9 adopts the anti-reverse injection device of a fully automatic rotary injection molding machine disclosed in (CN2547497Y). During discharge, the material pushed out by the pre-plasticizing screw pushes the anti-reverse ring towards the discharge port, opening the discharge channel. The material is pushed out from the inner hole of the anti-reverse ring into the storage cylinder. During injection, the injection oil pump rod injects the material from the storage cylinder into the injection port of the upper mold 5. Simultaneously, the material pushes the anti-reverse ring away from the discharge port, causing... The inner conical surface of the check ring is in close contact with the outer conical surface of the top ring, and the discharge channel is closed, preventing the rubber material from returning to the pre-plasticized screw sleeve in reverse. The top of the platform 1 is also equipped with a cleaning mechanism 7 that works in conjunction with the lower mold 6, and the bottom of the inner cavity of the platform 1 is equipped with a chip removal mechanism 8 that works in conjunction with the cleaning mechanism 7. By opening the cleaning mechanism 7, the waste material remaining on the top of the lower mold 6 is cleaned away, allowing the waste material to fall into the interior of the platform 1 for easy collection. At the same time, opening the chip removal mechanism 8 screens the waste material that falls into the interior of the platform 1, thereby separating waste material of different sizes. By screening out the larger waste particles, the waste material of different sizes is discharged from two different channels. The large waste particles are crushed separately and then discharged out together with the small particles, which facilitates the subsequent unified collection by the staff and improves the efficiency and convenience of waste recycling.

[0030] refer to Figure 2 , Figure 3 , Figure 4 The cleaning mechanism 7 includes a second cylinder 701 bolted to one side of the base 1. A U-shaped plate 702 is bolted to the output end of the second cylinder 701. A sliding frame 704, which is slidably connected to the base 1, is bolted to the top of the U-shaped plate 702. A brush 705, which works in conjunction with the lower mold 6, is bolted to the top of the sliding frame 704 away from the second cylinder 701. By opening the cleaning mechanism 7, the waste material remaining on the top of the lower mold 6 is swept away, allowing the waste material to fall into the interior of the base 1 for easy collection. The brush 705 can be detached from the top of the sliding frame 704, allowing for the replacement of a suitable brush 705 according to the size of the mold, ensuring that the brush 705 can completely clean the top area of ​​the mold.

[0031] refer to Figure 3 , Figure 4The bottom of the U-shaped plate 702 is bolted to a first linear rack 703 that is slidably connected to the base 1. A gear 706, rotatably connected to the base 1, meshes with the side of the first linear rack 703 furthest from the second cylinder 701. A second linear rack 707 meshes with the side of the gear 706 furthest from the first linear rack 703. A pusher plate 708, slidably connected to the base 1, is welded to the end of the second linear rack 707 furthest from the gear 706. A brush 705 is provided on the top of the base 1 near the pusher plate 708. The guide chute 709 cleans the waste residue on the top of the lower mold 6 by driving the brush 705, while the pusher plate 708 retracts into the base 1 and exposes the screening screen 808. This allows the waste swept out of the top of the lower mold 6 by the brush 705 to slide down the guide chute 709 onto the top of the screening screen 808, instead of falling onto the top of the pusher plate 708. For example, the aperture of the screening screen 808 can be set to one centimeter, so that only large particles larger than one centimeter will be screened onto the top of the screening screen 808. Although some waste may roll down quickly and fall onto the top of the pusher plate 708, the falling waste can also be scooped onto the top of the screening screen 808 by the guide chute 709 as the pusher plate 708 slides into the base 1. The brush 705 is made of polyetheretherketone (PEEK) special engineering plastic, which can withstand the high temperatures when the mold is opened, ensuring that the brush 705 will not melt or deform.

[0032] refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 The chip removal mechanism 8 includes a collection trough 803 located in the inner cavity of the platform 1 at the end of the pusher plate 708 away from the guide chute 709. A first motor 801, bolted to the platform 1, is installed at the bottom of the second cylinder 701. A discharge auger 802 is rotatably connected to the bottom of the inner cavity of the collection trough 803. The end of the discharge auger 802 away from the collection trough 803 is bolted to the output end of the first motor 801. A shaking frame 807 is slidably connected to the bottom of the pusher plate 708 inside the platform 1. A screening screen 808 is bolted to the top of the shaking frame 807. Both ends of the shaking frame 807 are equipped with return springs 809 through spring fixing parts. A chip removal trough 812, communicating with the bottom of the inner cavity of the collection trough 803, is opened at the bottom of the screening screen 808 inside the platform 1. By opening the chip removal mechanism 8, the waste falling into the inner cavity of the platform 1 is screened, thereby separating waste of different sizes. This allows for the separate crushing of large waste particles.

[0033] refer to Figure 2 , Figure 6 , Figure 7A rotating rod 804 is installed inside the shaking frame 807. The rotating rod 804 is rotatably connected to the base 1. The rotating rod 804 and the end of the discharge auger 802 near the first motor 801 are both fixedly sleeved with synchronous pulleys 805. The surfaces of the two synchronous pulleys 805 are connected with synchronous belts 806. An elliptical groove 810 is opened inside the shaking frame 807. The rotating rod 804 is located inside the elliptical groove 810 and is fixedly sleeved with a rocking rod 811 that is slidably connected to the elliptical groove 810. This drives the screening screen 808 to continuously sway left and right, thereby screening the small waste particles at the top down, while the large waste particles remain at the top of the screening screen 808.

[0034] refer to Figure 2 , Figure 8 At the bottom of the inner cavity of the collection tank 803, two symmetrically arranged crushing rollers 814 are rotatably connected to the base 1. A second motor 813 is bolted to one end of the base 1 near the crushing rollers 814. The output end of the second motor 813 is bolted to one end of one of the crushing rollers 814. The ends of the two crushing rollers 814 away from the second motor 813 are each bolted with meshing circular gears 815. By turning on the second motor 813, the two crushing rollers 814 are driven to mesh with each other using the two circular gears 815, so that the two crushing rollers 814 move in opposite directions synchronously. The rotating mechanism individually crushes large particles of waste falling into the collection tank 803. The transmission ratio of the two circular gears 815 is 1:1, ensuring that the two crushing rollers 814 can rotate synchronously in both directions. The installation distance between the two crushing rollers 814 can be set to one centimeter. When large particles of waste larger than one centimeter cannot pass through the screening screen 808, they will be crushed by the crushing rollers 814. The crushing rollers 814 with a distance of one centimeter can crush large particles of waste to a size of one centimeter as much as possible, improving the uniformity of the particle size of the waste.

[0035] refer to Figure 2 , Figure 9 The inner cavity of the collection tank 803 is symmetrically provided with guide plates 816 bolted to the base 1 at the top of the two crushing rollers 814. A scraper plate 818 is slidably connected to the bottom of the guide plate 816. A positioning rod 817 is threadedly connected to one side of the bottom of the guide plate 816 and slidably connected to the scraper plate 818. A compression spring 819, which works with the scraper plate 818, is fitted on the outer surface of the positioning rod 817 through a spring fixing component. The scraper plate 818 slides back and forth at the bottom of the guide plate 816 by the compression spring 819, so that the bottom of the scraper plate 818 can be kept in contact with the top of the crushing roller 814 to scrape off the plastic waste remaining on the top of the crushing roller 814 and prevent the waste from adhering to the surface of the crushing roller 814 and affecting the subsequent crushing effect.

[0036] refer to Figure 1 , Figure 2 The top of the platform 1 is bolted to a positioning column 11 that is slidably connected to the sliding plate 4 on the side near the support frame 2; this column is used to guide and position the upper mold 5 as it slides up and down on the top of the lower mold 6.

[0037] refer to Figure 1 , Figure 2 The two ends of the platform 1 near the return spring 809 are bolted to a detachable housing 10. The end of the return spring 809 away from the shaking frame 807 is installed inside the detachable housing 10 through a spring fixing member. The detachable housing 12 can be removed from both sides of the platform 1 to replace the return spring 809 with insufficient elasticity, thus ensuring the screening effect.

[0038] refer to Figure 3 The platform 1 is located on one side of the bottom of the first motor 801 and has a discharge port 12 that is connected to the collection tank 803 and the chip removal tank 812 respectively; so that small particle waste and large particle waste after crushing are conveyed by the discharge auger 802 and discharged uniformly from the inside of the discharge port 12.

[0039] Brief description of the usage process: First, the first cylinder 3 is turned on to drive the upper mold 5 at the bottom to close with the lower mold 6; and the glue is injected into the injection port of the upper mold 5 through the glue injection device 9. After the glue cools and solidifies inside the upper mold 5 and the lower mold 6, the first cylinder 3 is turned on again to drive the upper mold 5 to move upward and open, so that the workers can take out the injection molded part. After the injection molded part is removed when the upper mold 5 and lower mold 6 are opened, the operator activates the second cylinder 701 to push the U-shaped plate 702 to slide to one side of the lower mold 6. This causes the U-shaped plate 702 to push the brush 705 to move on top of the lower mold 6 via the sliding frame 704, allowing the brush 705 to clean the waste material remaining on the top of the lower mold 6. Simultaneously, as the U-shaped plate 702 slides to the lower mold 6, it drives the first linear rack 703 to mesh with the gear 706, causing the gear 706 to rotate and mesh with the second linear rack 707. This, in turn, causes the pusher plate 708 at one end of the second linear rack 707 to slide inside the platform 1 towards one side of the second cylinder 701, retracting the pusher plate 708 into the platform 1 and exposing the screening screen 808. At this point, the waste material cleaned from the top of the lower mold 6 by the brush 705 can slide down the guide chute 709 to the top of the screening screen 808 without falling onto the pusher plate 708. Simultaneously, by activating the first motor 801, the first motor 801 is driven by the synchronous pulley 805 and the synchronous belt 806, thereby synchronously driving the discharge auger 802 and the rotating rod 804 to rotate. When the rotating rod 804 rotates, it drives the rocking rod 811 inside the elliptical groove 810 to rotate. This allows the rocking rod 811 to rotate to the left and right sides, pushing the screening screen 808 on top of the shaking frame 807 to slide left and right inside the platform 1 through the elliptical groove 810. At the same time, the shaking frame 807 uses the return springs 809 at both ends to quickly reset, so that the waste falling onto the screening screen 808 can be screened out by the continuous left and right shaking of the shaking frame 807. The small particles of waste are then sieved out and rolled onto the surface of the discharge auger 802 through the chip discharge groove 812, while the large particles of waste remain on the top of the screening screen 808.

[0040] Then, by activating the second cylinder 701, the U-shaped plate 702 moves in the opposite direction, causing the brush 705 to slide back to one side of the second cylinder 701. After the pusher plate 708 is driven by the first linear rack 703 meshing with the gear 706, which in turn drives the gear 706 to mesh with the second linear rack 707, the pusher plate 708 can slide out from inside the base 1 back to the top of the screening screen 808, thereby pushing the large particles of waste that cannot be screened at the top of the screening screen 808 into the collection tank 803.

[0041] Next, by turning on the second motor 813, one of the crushing rollers 814 is driven to rotate, so that the two crushing rollers 814 mesh with each other using two circular gears 815, so that the two crushing rollers 814 rotate synchronously in opposite directions, so that the large particles of waste falling into the collection tank 803 can be crushed into small particles of waste by the crushing rollers 814; finally, by driving the first motor 801 to drive the discharge auger 802 to rotate continuously, so that the discharge auger 802 can forcefully convey and discharge the crushed large particles of waste in the collection tank 803 and the small particles of waste falling directly from the chip discharge tank 812 to the discharge port 12 near the bottom of the first motor 801. Meanwhile, when large particles of waste fall downward from the collection tank 803, they can be guided obliquely by the guide plate 816 and the scraper plate 818, so that the waste is concentrated and falls between the two crushing rollers 814 for thorough crushing. At the same time, the scraper plate 818 slides back and forth at the bottom of the guide plate 816 using the positioning rod 817 and the compression spring 819. During the rotation of the crushing roller 814, when the scraper plate 818 contacts the protruding part of the crushing roller 814, it can squeeze the compression spring 819 and move upward. When the scraper plate 818 contacts the concave part of the crushing roller 814, it can move downward using the rebound force of the compression spring 819. This allows the bottom of the scraper plate 818 to remain in contact with the top of the crushing roller 814, scraping off the plastic waste remaining on the top of the crushing roller 814 and preventing the waste from adhering to the surface of the crushing roller 814 and affecting the subsequent crushing effect.
