Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, and more particularly to a device for cleaning residual material in an injection molding hopper. Background Art

[0002] The hopper assembly is a common component of injection molding machines and other high-end plastic and rubber equipment. Its function is to transport plastic granular raw materials to the plasticizing parts. Workers pour the granular raw materials into the hopper, and the granular raw materials continuously enter the plasticizing parts through the connecting pipe and are continuously consumed during the production process. Because an injection molding machine is usually used to produce multiple products, the type of granular raw materials added to the hopper will also change when the production plan changes. Therefore, in order to discharge the old material in the connecting pipe, the side discharge port will open and discharge most of the old material. However, due to the limited height of the discharge port design, the particles below the discharge port cannot be discharged, and some residual material particles will inevitably accumulate at the bottom of the connecting pipe. Currently, after changing the raw materials, injection molding machines usually test a few batches of products to discharge the residual material. However, this method is slow to clear the material and cannot intuitively understand the residual material remaining in the pipe, which reduces production efficiency.

[0003] For example: Chinese patent announcement number CN219133003U, announcement date June 6, 2023, the name of the utility model is injection molding machine material changing mechanism, the application discloses a residual material cleaning and material changing mechanism for an injection molding machine, including a base with a discharge port on it; a slide rail, symmetrically fixed on both sides of the base; a fixed plate, which is an inverted U-shape, with two side plates fixed on both sides of the base and located on the outside of the slide rail, and a top plate located above the discharge port and a through hole coaxial with the discharge port on the top plate; a slider, slidably connected to the slide rail; a material changing block, fixed on the slider, with a discharge port and a material changing port on it. This solution does not require dragging the barrel, and can directly drag the material changing block to switch the discharge port and the material changing port, which is simple and convenient. However, this solution has poor functionality. When encountering a temporary material change, it is impossible to clean up a large amount of material. Utility Model Content

[0004] The utility model overcomes the problem of temporary material change and large material change volume of injection molding equipment, and provides an injection molding hopper residual material cleaning device. This solution can realize the situation of large material change volume in injection molding equipment, shorten the product switching cycle, and is conducive to improving equipment production efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a device for cleaning residual material in an injection molding hopper, comprising a barrel and a material receiving assembly located below the barrel, an extended pipe is provided between the barrel and the material receiving assembly, a first slidable partition is provided between the barrel and the extended pipe, a first discharge portion is provided on the side of the barrel close to the extended pipe, and a second discharge portion is provided on the side of the extended pipe close to the material receiving assembly. In this solution, the barrel is the material storage and feeding structure of the injection molding equipment. The material in the barrel enters the extended pipe and then enters the material receiving assembly. The material receiving assembly can inject the material directly into the injection molding machine. When material change is required, the first discharge part on the barrel can be opened, and the injection molded material is discharged from the first discharge part. The first discharge part can discharge most of the material in the barrel, and then move the first partition to connect the barrel and the extended pipe, and introduce the residual material at the bottom of the barrel into the extended pipe, and then discharge the material into the material receiving assembly. If the material receiving assembly cannot accommodate the residual material, some material can be further discharged through the second discharge part on the extended pipe, thereby completing the cleaning of the residual material in the barrel, achieving more residual material cleaning and replacement, and shortening the material change cycle.

[0006] Preferably, the material receiving assembly includes a separating pipe and a slide seat provided at the bottom of the extending pipe, wherein the separating pipe is slidably connected to the slide seat. The separating pipe is used to load the remaining material in the extending pipe and then transfer and discharge the remaining material by sliding on the slide seat.

[0007] Preferably, the material receiving assembly further comprises a pipe base, to which the separation pipe is fixedly connected, and which is slidably connected to the slide. The separation pipe and the pipe base are fixedly connected, and the separation pipe can be moved on the slide by moving the pipe base. The separation pipe and the pipe base are also detachably fixedly connected, thereby allowing replacement of the separation pipe.

[0008] Preferably, the pipe base is movably connected to a limit guide block, which cooperates with the pipe base to form a groove that is slidably connected to the slide. A limit guide block is provided at the bottom of the pipe base. When the limit guide block is connected to the pipe base, a groove that cooperates with the slide is formed. The movable connection between the pipe base and the limit guide block is a vertical connection in the vertical direction. The size of the groove between the limit guide block and the pipe base can be adjusted to accommodate slides of different thicknesses.

[0009] Preferably, a rolling body is provided between the connecting pipe base and the slide seat, which can convert the frictional sliding between the connecting pipe base and the slide seat into rolling sliding, thereby reducing sliding friction and facilitating the movement of the connecting pipe base.

[0010] Preferably, the device further comprises an adjustment bracket, the extension pipe is fixed to the top of the adjustment bracket, and the slide is fixed to the bottom of the adjustment bracket. The extension pipe is arranged on the top of the adjustment bracket, and the height of the extension pipe can be adjusted by adjusting the bracket, that is, changing the distance between the extension pipe and the slide to accommodate different sizes of separation pipes.

[0011] Preferably, the slide is provided with limit blocks at both ends thereof, which can limit the movement limit position of the pipe base on the slide, prevent the pipe base from separating from the slide, and can also automatically calibrate the material receiving position and material discharging position of the separation pipe.

[0012] Preferably, the slide is provided with a discharge hole on a side away from the adjustment bracket. When the pipe base drives the separation pipe to the discharge position, the residual material in the separation pipe can be discharged through the discharge hole on the slide to clean the residual material.

[0013] Preferably, the connecting pipe base is provided with a base handle. The base handle on the connecting pipe base can facilitate the staff to move the connecting pipe base, so that the separating connecting pipe slides on the slide seat.

[0014] Preferably, the first discharge portion includes a discharge pipe connected to a discharge flange, with a second slidable partition disposed between the discharge flange and the discharge pipe. The discharge pipe is located at the bottom of the barrel, the discharge flange is connected to a discharge receiving device, and the second partition between the discharge pipe and the discharge flange acts as a valve to control the on / off flow of discharge.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) it can realize the situation of large material change in injection molding equipment, shorten the product switching cycle, and is conducive to improving the production efficiency of the equipment; (2) the movement effect of the separation pipe is better, which is conducive to material unloading and cleaning; (3) the adjustment bracket can adjust the height of the extended pipe to adapt to more types of separation pipes; (4) it has a limit structure, which can automatically calibrate the material receiving position and the material discharge position, and is more convenient to operate.

[0022] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: Figures 1 to 5 The shown device for cleaning residual material in an injection molding hopper includes a barrel 1, an extended pipe 3 and a material receiving assembly 2, and the three are arranged in sequence from top to bottom; the top of the barrel 1 is cylindrical and the bottom is conical, and an extended pipe 3 is arranged at the bottom of the barrel 1. The barrel 1 and the extended pipe 3 are connected together through a barrel seat 18. The extended pipe 3 is a tubular structure with a hollow column inside, which is vertically arranged at the bottom of the barrel seat 18, and the material receiving assembly 2 is arranged at the bottom of the extended pipe 3. The material receiving assembly 2 includes a separation pipe 7 and a slide 19 arranged at the bottom of the separation pipe 7. The separation pipe 7 is slidably connected to the slide 19, and the extended pipe is fixed above the material receiving assembly 2 by an adjusting bracket 11.

[0024] The barrel 1, the extended pipe 3 and the separating pipe 7 can be connected to carry out the injection of injection plastic; specifically, a first partition 4 is provided between the barrel 1 and the barrel seat 18, and a through hole is arranged on the first partition 4, and an axial through hole is arranged on the barrel seat 18. The through hole of the barrel seat 18 is aligned with the discharge hole on the barrel 1, and the first partition 4 can slide between the barrel 1 and the barrel seat 18. The staff can pull out the first partition 4 to align the through hole on the first partition 4 with the discharge hole of the barrel 1, so that the barrel 1 and the barrel seat 18 are connected, that is, the barrel 1 and the extended pipe 3 are connected, and when the staff pulls out the first partition 4 so that the through hole of the first partition 4 is staggered with the discharge hole of the barrel 1, the barrel 1 and the extended pipe 3 are separated, and the injection plastic cannot be passed. A material receiving assembly 2 is arranged at the bottom of the extended pipe 3, and is arranged in sequence from top to bottom as a separation pipe 7, a pipe base 8 and a slide 19; similarly, the separation pipe 7 is also a tubular structure with a hollow cylinder inside, and the separation pipe 7 is fixed to the pipe base 8 by bolts and other connecting parts. A through hole is also provided on the pipe base 8, and the through hole on the pipe base 8 is connected with the separation pipe 7, and an injection plastic hole is provided on the slide 19 at a position corresponding to the extended pipe 3, and the injection plastic hole is aligned with the through hole of the extended pipe 3. When the pipe base 8 and the separation pipe 7 are located at the bottom 2 of the extended pipe 3, the through hole on the extended pipe 3 and the slide 19 can be connected through the pipe base 8 and the extended pipe 3, so that the injection molding machine can be fed and injected.

[0025] A first discharge portion 5 is provided on the conical bottom of the barrel 1. The first discharge portion 5 includes a discharge pipe 15, a second partition plate 17 and a discharge flange 16. The discharge pipe 15 is arranged on the conical surface of the barrel 1 at an angle downward, which is beneficial to the discharge effect of the discharge pipe 15. One end of the discharge flange 16 is fixedly connected to the outlet position of the discharge pipe 15, and the other end of the discharge flange 16 can be connected to a receiving device (not shown in the figure) for receiving the discharged material for discharge recovery; the discharge port of the discharge pipe 15 is connected to the discharge flange 16. The through holes are aligned, and a second partition 17 is slidably arranged between the discharge pipe 15 and the discharge flange 16. Similarly, the second partition 17 is also provided with a through hole. When the second partition 17 is pulled so that the through hole on the second partition 17 is aligned with the discharge port of the discharge pipe 15, the discharge pipe 15 and the discharge flange 16 can be connected for discharge. When the second partition 17 is pulled so that the through hole on the second partition 17 is misaligned with the discharge port of the discharge pipe 15, the discharge pipe 15 and the discharge flange 16 are cut off. Similarly, a second discharge portion 6 is provided on the extended pipe 3. The structural arrangement of the second discharge portion 6 is similar to that of the first discharge portion 5. It is not fully shown in the figure and will not be repeated here.

[0026] When there is still a lot of injection plastic in the barrel 1, the separation pipe 7 at the bottom of the extended pipe 3 cannot load all the injection plastic in the barrel 1 at one time. At this time, the second partition 17 on the first discharge part 5 is opened, and the injection plastic in the barrel 1 is discharged through the discharge pipe 15. When the injection plastic in the barrel 1 is discharged to be aligned with the position of the discharge pipe 15, the injection plastic is no longer discharged, and there is still some residual material at the bottom of the cone at the bottom of the barrel 1. Move the first partition 4 so that the through hole of the first partition 4 is aligned with the through hole of the barrel seat 18, and the remaining residual material in the barrel 1 can be passed into the extended pipe 3, and then the material in the extended pipe 3 will enter the separation pipe 7. If all the remaining material is loaded into the separation pipe 7, the pipe base 8 can be moved to clean the injection plastic in the separation pipe 7; if there is also a lot of material in the extended pipe 3 that cannot be loaded by the separation pipe 7 at one time, the second discharge part 6 on the extended pipe 3 can be opened to further perform the discharge work and reduce the loading burden of the separation pipe 7. Finally, the cleaned separation pipe 7 is moved back to the bottom of the lengthened pipe 3, and then the production work of the new injection molding compound can be carried out.

[0027] It should be noted that one end of the slide 19 is arranged at the bottom of the extended pipe 3, and an injection hole is provided on the slide 19 at a position corresponding to the extended pipe 3 for feeding materials during normal injection molding.

[0028] It should also be noted that an adjustment bracket 11 is arranged between the material receiving assembly 2 and the extended pipe 3. The adjustment bracket 11 includes an adjustment base 20. Two adjustment plates 21 that can move in the vertical direction are arranged on the adjustment base 20. The extended pipe 3 is fixedly connected to the top of the two adjustment plates 21. The adjustment plate 21 and the adjustment base 20 are connected by bolts. The height of the adjustment plate 21 can be adjusted by tightening each bolt, so that the position of the adjustment plate 21 can be raised or lowered, thereby changing the distance between the extended pipe 3 and the slide 19, so that different types of separation pipes 7 can be arranged on the slide 19 to arrange suitable separation pipes 7.

[0029] The slide 19 is fixedly arranged on the adjustment base 20. The cross-section of the slide 19 is a T-shaped structure. The take-up base 8 is arranged on the upper surface of the slide 19. A limit guide block 9 is provided on both sides of the take-up base 8. The limit guide block 9 is an L-shaped structure. The limit guide block 9 is bolted to the side bottom of the take-up base 8 to form a slide groove structure, and then is slidably connected to the T-shaped slide 19. By tightening the bolts, the distance between the limit guide block 9 and the take-up base 8 can be adjusted to adapt to slides 19 of different thicknesses; in addition, the limit guide block 9 can also prevent the take-up base 8 from lateral displacement on the slide 19. To facilitate sliding between the pipe base 8 and the slide 19, a rolling element 10 is disposed between the pipe base 8 and the slide 19. Specifically, two mounting grooves 22 are provided at the bottom of both sides of the pipe base 8, with two rollers disposed in each mounting groove 22. This means that there is a roller at each of the four corners of the pipe base 8. The rollers are in rolling connection with the upper surface of the slide 19, which can greatly reduce the friction between the pipe base 8 and the slide 19. Furthermore, the bolt adjustment on the limiting guide block 9 and the pipe base 8 can better adapt to the size of the rolling element 10, resulting in a better rolling connection. To facilitate the movement of the splicing assembly 2 by the staff, a base handle 14 is also disposed on the pipe base 8.

[0030] This solution can solve the problem of large material change in injection molding equipment, shorten the product switching cycle, and help improve equipment production efficiency.

[0031] Example 2: Figures 1 to 5 The shown device for cleaning residual material in an injection molding hopper includes a barrel 1, an extended pipe 3 and a material receiving assembly 2, and the three are arranged in sequence from top to bottom; the top of the barrel 1 is cylindrical and the bottom is conical, and an extended pipe 3 is arranged at the bottom of the barrel 1. The barrel 1 and the extended pipe 3 are connected together through a barrel seat 18. The extended pipe 3 is a tubular structure with a hollow column inside, which is vertically arranged at the bottom of the barrel seat 18, and the material receiving assembly 2 is arranged at the bottom of the extended pipe 3. The material receiving assembly 2 includes a separation pipe 7 and a slide 19 arranged at the bottom of the separation pipe 7. The separation pipe 7 is slidably connected to the slide 19, and the extended pipe is fixed above the material receiving assembly 2 by an adjusting bracket 11.

[0032] The barrel 1, the extended pipe 3 and the separating pipe 7 can be connected to carry out the injection of injection plastic; specifically, a first partition 4 is provided between the barrel 1 and the barrel seat 18, and a through hole is arranged on the first partition 4, and an axial through hole is arranged on the barrel seat 18. The through hole of the barrel seat 18 is aligned with the discharge hole on the barrel 1, and the first partition 4 can slide between the barrel 1 and the barrel seat 18. The staff can pull out the first partition 4 to align the through hole on the first partition 4 with the discharge hole of the barrel 1, so that the barrel 1 and the barrel seat 18 are connected, that is, the barrel 1 and the extended pipe 3 are connected, and when the staff pulls out the first partition 4 so that the through hole of the first partition 4 is staggered with the discharge hole of the barrel 1, the barrel 1 and the extended pipe 3 are separated, and the injection plastic cannot be passed. A material receiving assembly 2 is arranged at the bottom of the extended pipe 3, and is arranged in sequence from top to bottom as a separation pipe 7, a pipe base 8 and a slide 19; similarly, the separation pipe 7 is also a tubular structure with a hollow cylinder inside, and the separation pipe 7 is fixed to the pipe base 8 by bolts and other connecting parts. A through hole is also provided on the pipe base 8, and the through hole on the pipe base 8 is connected with the separation pipe 7, and an injection plastic hole is provided on the slide 19 at a position corresponding to the extended pipe 3, and the injection plastic hole is aligned with the through hole of the extended pipe 3. When the pipe base 8 and the separation pipe 7 are located at the bottom 2 of the extended pipe 3, the through hole on the extended pipe 3 and the slide 19 can be connected through the pipe base 8 and the extended pipe 3, so that the injection molding machine can be fed and injected.

[0033] A first discharge portion 5 is provided on the conical bottom of the barrel 1. The first discharge portion 5 includes a discharge pipe 15, a second partition plate 17 and a discharge flange 16. The discharge pipe 15 is arranged on the conical surface of the barrel 1 at an angle downward, which is beneficial to the discharge effect of the discharge pipe 15. One end of the discharge flange 16 is fixedly connected to the outlet position of the discharge pipe 15, and the other end of the discharge flange 16 can be connected to a receiving device (not shown in the figure) for receiving the discharged material for discharge recovery; the discharge port of the discharge pipe 15 is connected to the discharge flange 16. The through holes are aligned, and a second partition 17 is slidably arranged between the discharge pipe 15 and the discharge flange 16. Similarly, the second partition 17 is also provided with a through hole. When the second partition 17 is pulled so that the through hole on the second partition 17 is aligned with the discharge port of the discharge pipe 15, the discharge pipe 15 and the discharge flange 16 can be connected for discharge. When the second partition 17 is pulled so that the through hole on the second partition 17 is misaligned with the discharge port of the discharge pipe 15, the discharge pipe 15 and the discharge flange 16 are cut off. Similarly, a second discharge portion 6 is provided on the extended pipe 3. The structural arrangement of the second discharge portion 6 is similar to that of the first discharge portion 5. It is not fully shown in the figure and will not be repeated here.

[0034] When there is still a lot of injection plastic in the barrel 1, the separation pipe 7 at the bottom of the extended pipe 3 cannot load all the injection plastic in the barrel 1 at one time. At this time, the second partition 17 on the first discharge part 5 is opened, and the injection plastic in the barrel 1 is discharged through the discharge pipe 15. When the injection plastic in the barrel 1 is discharged to be aligned with the position of the discharge pipe 15, the injection plastic is no longer discharged, and there is still some residual material at the bottom of the cone at the bottom of the barrel 1. Move the first partition 4 so that the through hole of the first partition 4 is aligned with the through hole of the barrel seat 18, and the remaining residual material in the barrel 1 can be passed into the extended pipe 3, and then the material in the extended pipe 3 will enter the separation pipe 7. If all the remaining material is loaded into the separation pipe 7, the pipe base 8 can be moved to clean the injection plastic in the separation pipe 7; if there is also a lot of material in the extended pipe 3 that cannot be loaded by the separation pipe 7 at one time, the second discharge part 6 on the extended pipe 3 can be opened to further perform the discharge work and reduce the loading burden of the separation pipe 7. Finally, the cleaned separation pipe 7 is moved back to the bottom of the lengthened pipe 3, and then the production work of the new injection molding compound can be carried out.

[0035] It should be noted that one end of the slide 19 is positioned at the bottom of the extended pipe 3, and an injection molding hole is provided on the slide 19 at a position corresponding to the extended pipe 3 for feeding the material during normal injection molding. A discharge hole 13 is provided at the other end of the slide 19. Once the separation pipe 7 is loaded with the remaining injection molding material, the pipe base 8 is moved to the position of the discharge hole 13, aligning the through-hole of the pipe base 8 with the discharge hole 13. Similarly, the discharge hole 13 is connected to a residual material receiving device for collecting the residual material in the separation pipe 7.

[0036] It should also be noted that an adjustment bracket 11 is arranged between the material receiving assembly 2 and the extended pipe 3. The adjustment bracket 11 includes an adjustment base 20. Two adjustment plates 21 that can move in the vertical direction are arranged on the adjustment base 20. The extended pipe 3 is fixedly connected to the top of the two adjustment plates 21. The adjustment plate 21 and the adjustment base 20 are connected by bolts. The height of the adjustment plate 21 can be adjusted by tightening each bolt, so that the position of the adjustment plate 21 can be raised or lowered, thereby changing the distance between the extended pipe 3 and the slide 19, so that different types of separation pipes 7 can be arranged on the slide 19 to arrange suitable separation pipes 7.

[0037] The slide 19 is fixedly arranged on the adjustment base 20. The cross-section of the slide 19 is a T-shaped structure. The take-up base 8 is arranged on the upper surface of the slide 19. A limit guide block 9 is provided on both sides of the take-up base 8. The limit guide block 9 is an L-shaped structure. The limit guide block 9 is bolted to the side bottom of the take-up base 8 to form a slide groove structure, and then is slidably connected to the T-shaped slide 19. By tightening the bolts, the distance between the limit guide block 9 and the take-up base 8 can be adjusted to adapt to slides 19 of different thicknesses; in addition, the limit guide block 9 can also prevent the take-up base 8 from lateral displacement on the slide 19. To facilitate sliding between the pipe base 8 and the slide 19, a rolling element 10 is disposed between the pipe base 8 and the slide 19. Specifically, two mounting grooves 22 are provided at the bottom of both sides of the pipe base 8, with two rollers disposed in each mounting groove 22. This means that there is a roller at each of the four corners of the pipe base 8. The rollers are in rolling connection with the upper surface of the slide 19, which can greatly reduce the friction between the pipe base 8 and the slide 19. Furthermore, the bolt adjustment on the limiting guide block 9 and the pipe base 8 can better adapt to the size of the rolling element 10, resulting in a better rolling connection. To facilitate the movement of the splicing assembly 2 by the staff, a base handle 14 is also disposed on the pipe base 8.

[0038] Limit blocks 12 are also provided at both ends of the slide 19. The limit block 12 at one end is arranged near the injection molding hole for feeding the injection molding material, and the limit block 12 at the other end is arranged at the position of the discharge hole 13. The limit blocks 12 can limit the extreme position of the material receiving component 2 on the slide 19, preventing the material receiving component 2 from detaching from the slide 19. Of course, when the material receiving component 2 is respectively in contact with the limit blocks 12 at both ends, the material receiving component 2 is just aligned with the bottom of the extended pipe 3 (i.e., at the material receiving position) and the position of the discharge hole 13 (i.e., at the discharge position), thereby greatly reducing the difficulty of calibrating the material receiving component 2 at the two positions and improving the material receiving and discharge effects.

[0039] This solution can solve the problem of large material change in injection molding equipment, shorten the product switching cycle, and help improve equipment production efficiency.
