Description

Technical Field

[0001] The present invention relates to the technical field of plastic waste recycling and processing injection molding machines, and specifically relates to an injection molding machine for plastic product processing. Background Art

[0002] An injection molding machine can assist in the shaping of plastics. Through the injection molding machine and its supporting cavities, plastics can be shaped. At the same time, in plastic waste recycling and processing, after melting the plastic waste by injection molding, the plastic waste to be recycled can be manufactured into products with specific shapes, functions, and properties through various processing technologies and equipment, so that the plastic after injection molding cools and solidifies to form the required plastic products, realizing the recycling of plastic waste.

[0003] For example, the patent with the publication number CN220331817U discloses a plastic product injection molding machine, including an injection molding machine body and a feed hopper body. On the right side of the top of the injection molding machine body, an electric telescopic rod is installed, and a connecting plate is fixed to the top of the output shaft of the electric telescopic rod. On the left side of the connecting plate, a lifting platform is fixed. On the top of the lifting platform, a first motor is fixed, and the output shaft of the first motor penetrates through the lifting platform and is bolted to a rotating rod. At the bottom end of the rotating rod, a mounting frame is bolted; when the injection molding machine is idle, it can effectively clean the dust on the inner wall of the feed hopper automatically, avoiding a large amount of dust accumulation inside the feed hopper, improving the processing quality of plastic products. Moreover, this injection molding machine also has a lifting function, which can lift the plastic raw materials, reducing the labor burden of the staff, facilitating the staff to perform the feeding operation, and providing convenience for the staff.

[0004] For example, the patent with the publication number CN218906120U discloses a PP plastic injection molding machine, including a material conveying cylinder, a material conveying motor installed on the right side of the material conveying cylinder, and a discharge channel installed on the left side of the material conveying cylinder. Above the material conveying cylinder, a feeding mechanism for crushing PP plastic particles is installed. On the left side of the material conveying cylinder and on the outer surface of the discharge channel, a sealing mechanism for preventing raw materials from overflowing is installed. The feeding mechanism includes a feeding box arranged above the material conveying cylinder; this PP plastic injection molding machine solves the problems that when a common injection molding machine is used, plastic particles are added into the interior of the material conveying cylinder for heating and melting and then conveyed to the discharge channel. If the plastic particles are too large, incomplete melting will occur, thus affecting the quality of the later products. At the same time, during the injection process, the sealing between the discharge channel and the pouring port of the mold is not high, resulting in the overflow of raw materials.

[0005] For another example, a patent with the publication number CN221540552U discloses a plastic injection molding machine, which includes an injection molding machine body. A driving device is installed inside the injection molding machine body, and an upper template is installed at the output end of the driving device. A lower template is fixedly connected inside the injection molding machine. An adjusting structure is provided on one side of the upper template. The adjusting structure includes a fixing plate, which is fixedly connected to the upper template. A fixing frame is fixedly connected to the side of the fixing plate away from the upper template, and a servo motor is fixedly connected inside the fixing frame. After the injection molding is completed, the plastic product is attached inside the upper template. The servo motor is started, and the servo motor drives the adjusting disk to rotate. The adjusting disk makes the adjusting frame move back and forth horizontally by means of an adjusting rod, so that the two impact plates repeatedly impact the upper template. The vibration generated by the impact causes the plastic product to break away from the upper template, improving the demolding efficiency and thus the production efficiency. When the molten liquid in the injection molding machine is injected into the mold closing structure, it is necessary to first clean the injection head of the injection molding machine. For example, the waste material solidified during the previous injection processing blocked in the injection head is removed to keep the injection of the plastic smooth. Some existing injection molding machines are not convenient for mechanically handling the solidified matter in the injection head, which is not conducive to the intelligent operation of the injection molding machine. In addition, the solidified matter cleaned from the injection head is plastic material, and this part of the plastic material can be recycled. Some existing injection machines do not have the function of autonomously recycling plastic materials, resulting in a certain material waste rate during the injection molding process.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original plastic product processing injection molding machine. Summary of the Invention

For example, the waste material solidified during the previous injection processing blocked in the injection head is removed to keep the injection of the plastic smooth. Some existing injection molding machines are not convenient for mechanically handling the solidified matter in the injection head, which is not conducive to the intelligent operation of the injection molding machine.

[0008] To achieve the above object, the present invention provides the following technical solution: An injection molding machine for plastic product processing, including a processing table and an injection section fixedly installed on the processing table.

A fixed mold is fixedly installed on the guiding rod, and a movable mold is slidably installed on the guiding rod. The movable mold moves to close the mold with the fixed mold. A hydraulic rod for driving the movement of the movable mold is installed on the fixed frame. An injection channel pipe is installed on the fixed mold. The injection channel pipe moves to be engaged and connected with the injection head in a through manner, and a discharge channel that moves up and down is arranged between the injection channel pipe and the injection head. The discharge channel moves down to be engaged and connected with the injection head in a through manner. A displacement mechanism for lifting and adjusting the corresponding position of the discharge channel is arranged on the processing table.

[0009] Preferably, an electric slide rail is fixedly installed on the upper surface of the processing table. A sliding seat is slidably installed on the electric slide rail, and the sliding seat is fixedly connected with the fixed frame.

[0010] Preferably, the displacement mechanism includes a support frame fixedly installed on the processing table. A sliding support is slidably connected to the support frame, and the sliding support is fixedly connected with the discharge channel.

[0011] Preferably, a lead screw is rotatably connected to the support frame, and the sliding support is threadedly connected with the lead screw.

[0012] Preferably, a transmission mechanism for recycling the plastic waste discharged from the discharge channel is arranged on the processing table.

[0013] Preferably, the transmission mechanism includes a material receiving box fixedly installed on the processing table. A material conveying box is connected through the side of the material receiving box. A lifting pipe is connected through the side of the material conveying box. The upper discharge port of the lifting pipe is correspondingly arranged above the feeding section. A spiral feeding rod is rotatably installed inside the lifting pipe.

[0014] Preferably, a chute is opened on the inner side wall of the material receiving box. A positioning slider is slidably installed in the chute. A scraping blade is fixedly installed on the positioning slider, and the sharp surface at the lower end of the scraping blade is attached to the inner bottom surface of the material receiving box.

[0015] Preferably, a hollow column is fixedly installed on the outer surface of the material receiving box. A rotating rod is rotatably connected through the hollow column. A scroll spring is elastically connected between the rotating rod and the inner wall of the hollow column. A transmission telescopic rod is rotatably connected to the scraping blade, and the telescopic end of the transmission telescopic rod is fixedly connected with the rotating rod. A lifting frame is fixedly installed on the sliding support. A rack is fixedly installed on the lifting frame. A gear is meshed and connected beside the rack, and the gear is coaxially fixedly connected with the rotating rod.

[0016] Preferably, a vibration feeding base is fitted and installed on the bottom surface of the material feeding box, and the surface of the vibration feeding base is inclined; an electric telescopic rod is fixedly installed at the bottom of the processing table, the output end of the electric telescopic rod is fixedly connected with a bottom bracket, and a plurality of vibration cylinders are equidistantly installed on the bottom bracket, and the vibration cylinders are correspondingly arranged below the vibration feeding base.

[0017] Preferably, a cylindrical rod is fixedly connected to the bottom of the processing table, a vibration spring is sleeved outside the cylindrical rod, and the vibration spring is elastically connected between the processing table and the bottom bracket.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: for the injection molding machine used for plastic product processing, the recycled plastic material is introduced into the heating section and melted into a liquid state, and the melted plastic material is injected into the fixed mold and the moving mold after mold clamping through the injection head. After the material solidifies and forms a plastic product, and through the lifting and moving discharge channel, the plastic material solidified and blocked inside the injection head can be guided and cleaned, maintaining the smoothness of the injection molding of the plastic product.

[0019] Furthermore, a displacement mechanism for adjusting the position corresponding to the lifting and adjusting discharge channel is arranged on the processing table. Under the screw thread transmission of the screw rod and the sliding bracket, the discharge channel can be controlled to move up and down, adjusting the position of the discharge channel corresponding to the injection head. When the discharge channel is controlled to be connected with the injection head in a through manner, under the action of the injection pressure, the plastic material blocked and solidified in the injection head is sprayed into the discharge channel under high pressure, so as to guide and clean the plastic material and maintain the smoothness of the injection head.

[0020] The fixed frame is controlled to move horizontally through the electric slide rail and the slide seat, adjusting the position of the fixed mold corresponding to the side of the injection head. Horizontally moving the fixed mold makes the injection channel pipe connected with the injection head in a through manner, maintaining the smoothness of the injection channel and assisting in the preparation of plastic products.

[0021] Furthermore, a transmission mechanism for recycling the plastic waste discharged from the discharge channel is arranged on the processing table. The plastic waste sprayed out under high pressure from the discharge channel enters the material receiving box. During the longitudinal movement of the sliding bracket, the scraping blade can be controlled to move horizontally in the material receiving box. The scraping blade pushes the plastic waste and some plastic hot melt liquid into the material feeding box, and the plastic waste in the material feeding box enters the feeding section through the lifting pipe, realizing the recycling of the plastic waste.

[0022] The electric telescopic rod is operated to control the bottom bracket to move up and down reciprocally. The bottom bracket drives the vibration cylinder to move up and down corresponding to the bottom of the vibration feeding base, so that the vibration feeding base generates a vibration force, ensuring that the plastic waste in the material feeding box can quickly move to the position of the lifting pipe port, assisting in the recycling of plastic materials and reducing the material waste rate during the processing of plastic products.

Detailed implementation mode

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figures 1 - 14 , the present invention provides the following technical solutions: An injection molding machine for plastic product processing, including a processing table 1 and an injection section 2 fixedly installed on the processing table 1. A feeding section 3 is connected through the injection section 2, and an injection head 4 is installed at the end of the injection section 2. A fixing frame 5 is horizontally slidably arranged on the processing table 1. A guide rod 6 is fixedly installed on the fixing frame 5. A stationary mold 7 is fixedly installed on the guide rod 6, and a moving mold 8 is slidably installed on the guide rod 6. The moving mold 8 moves to close the mold with the stationary mold 7. A hydraulic rod 9 for driving the moving mold 8 to move is installed on the fixing frame 5; An injection channel pipe 16 is installed on the stationary mold 7. The injection channel pipe 16 moves to be snap-fitted and connected with the injection head 4 in a through manner, and a discharge channel 12 that moves up and down is arranged between the injection channel pipe 16 and the injection head 4. The discharge channel 12 moves down to be snap-fitted and connected with the injection head 4 in a through manner. A displacement mechanism for lifting and adjusting the corresponding position of the discharge channel 12 is arranged on the processing table 1.

[0040] An electric slide rail 10 is fixedly installed on the upper surface of the processing table 1. A sliding seat 11 is slidably installed on the electric slide rail 10. The sliding seat 11 is fixedly connected with the fixing frame 5.

[0041] The displacement mechanism includes a support frame 13 fixedly installed on the processing table 1. A sliding support 14 is slidably connected to the support frame 13. The sliding support 14 is fixedly connected with the discharge channel 12.

[0042] A lead screw 15 is rotatably connected to the support frame 13. The sliding support 14 is threadedly connected with the lead screw 15.

[0043] The plastic material is added into the injection section 2 through the feeding section 3. The plastic material is heated and melted under the action of high temperature and high pressure inside the injection section 2 to form a molten plastic in a viscous flow state, and finally sprays out through the injection head 4. During injection processing, the movement of the injection channel tube 16 is controlled to be engaged and connected with the movement of the injection head 4 in a through manner. The injection liquid inside the injection head 4 enters the fixed mold 7 and the moving mold 8 after mold clamping, and solidifies and forms inside the fixed mold 7 and the moving mold 8 to form plastic products.

[0044] Before injection processing, check whether there is a blockage inside the injection head 4. Control the sliding seat 11 to engage and move on the electric slide rail 10. The sliding seat 11 drives the fixing frame 5 to move horizontally, so that the injection channel tube 16 moves away from the injection head 4. If there is a solidified material of plastic material blocked inside the injection head 4, at this time, operate the motor on the support frame 13 to control the screw rod 15 to rotate. Under the screw drive, the sliding support frame 14 engages and moves downward on the support frame 13. The sliding support frame 14 drives the discharge channel 12 to move downward and engage with the outside of the injection head 4. At this time, pre-inject plastic material, and under the action of high pressure, the solidified plastic material in the injection head 4 sprays outwards. The sprayed plastic material enters the discharge channel 12, and under the conduction action of the discharge channel 12, the plastic waste can be collected and cleaned.

[0045] Embodiment 2: On the basis of Embodiment 1, a transmission mechanism is also disclosed, and its specific structure is as follows: A transmission mechanism for recycling and discharging the plastic waste discharged from the discharge channel 12 is provided on the processing table 1. The transmission mechanism includes a material receiving box 17 fixedly installed on the processing table 1. A material transfer box 18 is connected through the side of the material receiving box 17.

The upper discharge port of the lifting pipe 19 is correspondingly arranged above the feeding section 3; A spiral feeding rod 20 is rotatably installed inside the lifting pipe 19.

[0046] A chute 21 is opened on the inner side wall of the material receiving box 17. A positioning slider 22 is slidably installed in the chute 21. A scraping blade 23 is fixedly installed on the positioning slider 22. The sharp surface at the lower end of the scraping blade 23 is attached to the inner bottom surface of the material receiving box 17.

[0047] A hollow column 24 is fixedly installed on the outer surface of the material receiving box 17. A rotating rod 25 is rotatably connected through the hollow column 24. A scroll spring 27 is elastically connected between the rotating rod 25 and the inner wall of the hollow column 24; A transmission telescopic rod 26 is rotatably connected to the scraping blade 23. The telescopic end of the transmission telescopic rod 26 is fixedly connected to the rotating rod 25; A lifting frame 28 is fixedly installed on the sliding support frame 14. A rack 29 is fixedly installed on the lifting frame 28. A gear 30 is meshed beside the rack 29. The gear 30 is coaxially fixedly connected to the rotating rod 25.

[0048] A vibration feeding base 31 is fitted and installed at the bottom surface of the material transfer box 18, and the surface of the vibration feeding base 31 is inclined; an electric telescopic rod 32 is fixedly installed at the bottom of the processing table 1, the output end of the electric telescopic rod 32 is fixedly connected with a bottom bracket 33, and a plurality of vibration cylinders 34 are equidistantly installed on the bottom bracket 33, and the vibration cylinders 34 are correspondingly arranged below the vibration feeding base 31.

[0049] A cylindrical rod 35 is fixedly connected to the bottom of the processing table 1, a vibration spring 36 is sleeved outside the cylindrical rod 35, and the vibration spring 36 is elastically connected between the processing table 1 and the bottom bracket 33.

[0050] The discharge channel 12 moves downward to be snap-fitted with the material receiving box 17, and the plastic waste in the discharge channel 12 enters the material receiving box 17. When the sliding bracket 14 moves longitudinally, it drives the lifting frame 28 to move synchronously, so that the rack 29 fixed on the lifting frame 28 moves synchronously with it. Under the meshing transmission of the rack 29 and the gear 30, the rotating rod 25 can be driven to rotate. The rotating rod 25 drives the transmission telescopic rod 26 to rotate, and the transmission telescopic rod 26 automatically contracts and pushes the scraping blade 23 to move horizontally along the direction of the chute 21.

Some injection plastic liquid may be received inside the material receiving box 17, and the plastic liquid is easy to solidify and form at the bottom of the material receiving box 17. Under the pushing action of the scraping blade 23, the semi-solidified plastic material can be pushed into the material transfer box 18 for better recycling and treatment of the plastic waste liquid.

[0051] The plastic waste entering the material transfer box 18 moves obliquely and is conveyed on the inclined surface at the upper end of the vibration feeding base 31 and enters the port of the lifting pipe 19.

The spiral feeding rod 20 transports the plastic waste at the bottom of the lifting pipe 19 to the upper part, and the plastic waste at the upper port of the lifting pipe 19 enters the feeding section 3, so as to realize the automatic recycling and utilization of the plastic waste.

[0052] During the process of the material transfer box 18 conveying materials, the electric telescopic rod 32 is operated to control the reciprocating up and down movement of the bottom bracket 33. The bottom bracket 33 drives the vibration cylinders 34 to move up and down synchronously. The up and down vibration of the vibration cylinders 34 acts on the surface of the vibration feeding base 31 to keep the vibration feeding base 31 in a vibrating state, and better transports the plastic waste in the material transfer box 18 to the position of the lifting pipe 19 to assist in completing the plastic recycling.
