Injection molding machine hopper moving mechanism

Abstract

This application discloses a hopper moving mechanism for an injection molding machine, relating to the field of injection molding machines. It includes a sliding plate, a U-shaped slide block, and a hopper body. The sliding plate and U-shaped slide block are equipped with sliding components and fixing components. The U-shaped slide block and hopper body are equipped with mounting components. The fixing components include a material passage tube fixedly connected to the lower surface of the U-shaped slide block. This application utilizes the cooperative arrangement of the material passage tube, fixing tube, and pull plate. In use, the sliding component slides the U-shaped slide block on the sliding plate, aligning the material passage tube with one of the discharge ports. Then, by rotating the ring and swinging the pull plate, the T-shaped rod is moved out of the arc-shaped groove. Releasing the pull plate allows the spring to push the fixing tube downwards, inserting it into the annular groove, preventing the U-shaped slide block from sliding. This minimizes the problem of insufficient fixing of the discharge port slide block, which can cause wobbling during use, easily leading to hopper movement and reduced stability.

Description

Technical Field

[0001] This application relates to the field of injection molding machines, and in particular to the hopper movement mechanism of injection molding machines. Background Technology

[0002] The feeding mechanism is a common component of injection molding machines. Typically, the feeding mechanism includes a hopper that is directly connected to the barrel. Plastic raw materials are fed into the barrel through the hopper, where they are vulcanized and injected into the mold.

[0003] The utility model patent with announcement number CN218227617U proposes a hopper structure for an injection molding machine, including a slide plate with material discharge holes at both ends. It also includes a hopper sliding assembly comprising a material outlet slide block, rollers, and rollers. The material outlet slide block has sliding grooves on both sides that are slidably connected to the sides of the slide plate. A circular hole is provided in the center of the material outlet slide block. Rollers are rotatably connected to the mounting grooves at the four bottom corners of the material outlet slide block via rollers, and the rollers are rotatably connected to the upper side of the slide plate. A hopper support control assembly is installed on top of the material outlet slide block, and the top of the hopper support control assembly is connected to the bottom of the hopper.

[0004] The injection molding machine hopper structure described above moves the hopper by sliding the sprue slide on the slide plate. However, the sprue slide lacks fixation, causing it to shake during use and easily move the hopper, resulting in reduced stability. Utility Model Content

[0005] To address the aforementioned issues, this application provides a hopper moving mechanism for injection molding machines.

[0006] The injection molding machine hopper moving mechanism provided in this application adopts the following technical solution:

[0007] The injection molding machine hopper moving mechanism includes a sliding plate, a U-shaped slide block, and a hopper body. The sliding plate and the U-shaped slide block are equipped with sliding and fixing components. The U-shaped slide block and the hopper body are equipped with mounting components. The fixing component includes a material passage tube fixedly connected to the lower surface of the U-shaped slide block. A fixing tube is sleeved on the material passage tube. Multiple springs in a ring array are fixedly connected to the top of the fixing tube. The end of each spring away from the fixing tube is fixedly connected to the U-shaped slide block. A rotating ring is rotatably connected to the top of the side wall of the fixing tube. A pull plate is fixedly connected to one side wall of the rotating ring. An arc-shaped groove with an open end is formed on the upper surface of the pull plate. A T-shaped rod is fixedly connected to the lower surface of the U-shaped slide block above the arc-shaped groove. The vertical section of the T-shaped rod is slidably disposed within the arc-shaped groove. Material outlets are formed at both ends of the upper surface of the sliding plate. Ring grooves adapted to the fixing tube are formed at both ends of the upper surface of the sliding plate outside the material outlets.

[0008] By adopting the above technical solution, during use, the U-shaped slide block is slid on the slide plate by the sliding component, so that the feed tube is aligned with one of the feed ports. Then, by rotating the ring and swinging the pull plate, the T-shaped rod is moved out of the arc groove. The pull plate is released, and the fixed tube is pushed down by the spring rebound and inserted into the annular groove to prevent the U-shaped slide block from sliding. This avoids the problem of the feed port slide block not being fixed, which may cause shaking during use, easily move the hopper, and reduce stability.

[0009] Preferably, the sliding assembly includes two fixed rods fixedly connected inside the U-shaped slide block, each fixed rod having multiple rollers rotatably connected to it. The rollers are in contact with the upper surface of the slide plate. The slide plate has grooves on both side walls. The bottom of both side walls inside the U-shaped slide block is fixedly connected to a slider, which is slidably disposed within the groove.

[0010] By adopting the above technical solution, after the fixed tube is removed from the annular groove, the roller is rolled on the slide plate by pulling the pull plate, which drives the U-shaped slide to move. The stability of the U-shaped slide is improved by the cooperation of the slide groove and the slider.

[0011] Preferably, the mounting assembly includes a discharge pipe fixedly connected to the bottom end of the hopper body, a mounting plate fixedly connected to the bottom end of the discharge pipe, a plurality of first bolts provided on the upper surface of the mounting plate, the first bolts passing through the mounting plate and threadedly connected to the U-shaped slide, and the discharge pipe communicating with the feed pipe.

[0012] By adopting the above technical solution, the mounting plate is fixedly connected to the U-shaped slide block by the first bolt, which facilitates the disassembly and installation of the hopper body.

[0013] Preferably, the lower surface of the U-shaped slide is fixedly connected to a plurality of annular array guide rods located outside the feed tube. The top end of the fixed tube is provided with a plurality of guide holes adapted to the guide rods. The guide rods are slidably disposed in the guide holes respectively, and the springs are respectively sleeved on the guide rods.

[0014] By adopting the above technical solution, the stability of the fixed tube lifting and lowering can be improved through the guide rod and guide hole, and the spring bending can be prevented.

[0015] Preferably, a plurality of support rods are fixedly connected to the upper surface of the mounting plate, the top ends of the support rods are fixedly connected to the hopper body, a cover plate is installed on the top of the hopper body, and a viewing window is fixedly connected to the side wall of the hopper body.

[0016] By adopting the above technical solution, the stability of the hopper body is improved by the support rod, the hopper body is easily opened and closed by the cover plate, and the remaining material in the hopper body can be viewed through the viewing window.

[0017] Preferably, positioning blocks are fixedly connected to the two side walls of the slide plate at both ends of the slide groove.

[0018] By adopting the above technical solution, when the U-shaped slide is moved to both ends of the slide plate, the positioning block prevents the U-shaped slide from sliding out of the slide plate while positioning the U-shaped slide so that the feed tube is located directly above the feed port.

[0019] Preferably, the upper surface of the slide plate is provided with second bolts on all four sides of one of the feed ports, and the screw ends of the second bolts pass through the slide plate to form a sliding configuration.

[0020] By adopting the above technical solution, the slide plate can be easily fixed to the external injection molding machine with the second bolt, so that the discharge port at this location is aligned with the feed port of the injection molding machine, and the material in the hopper body is discharged into the injection molding machine.

[0021] Preferably, the upper surface of the slide plate has multiple receiving holes, and the nut end of the second bolt is located in each of the receiving holes.

[0022] By adopting the above technical solutions, the nut end of the second bolt is hidden through the receiving hole, preventing the second bolt from extending onto the upper surface of the slide plate and affecting the sliding of the U-shaped slide block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the cooperative arrangement of structures such as the feed pipe, the fixed pipe, and the pull plate. During use, the U-shaped slide block is slid on the slide plate by the sliding component, so that the feed pipe is aligned with one of the discharge ports. Then, by rotating the ring and swinging the pull plate, the T-shaped rod is moved out of the arc groove. The pull plate is released, and the fixed pipe is pushed downward by the spring rebound and inserted into the annular groove to prevent the U-shaped slide block from sliding. This avoids the problem of the feed port slide block lacking fixation, which can cause shaking during use, easily move the hopper, and reduce stability.

[0025] 2. After the fixed tube is removed from the annular groove, the roller is rolled on the slide plate by pulling the pull plate, which drives the U-shaped slide to move. The slide groove and the slider improve the stability of the U-shaped slide when it moves. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a hopper moving mechanism for an injection molding machine.

The pull plate 6 is fixedly connected to one side wall of the rotating ring 24. The arc groove 25 is opened on the upper surface of the pull plate 6 and one end is open. The T-shaped rod 26 is fixedly connected to the lower surface of the U-shaped slide 2 and is located above the arc groove 25. The vertical section of the T-shaped rod 26 is slidably set in the arc groove 25. There are two discharge ports 7, which are respectively opened at both ends of the upper surface of the slide plate 1. There are two annular grooves 8, which are respectively opened at both ends of the upper surface of the slide plate 1 and are located outside the discharge ports 7. The fixed tube 5 is adapted to the annular groove 8.

[0035] Reference Figure 1 , Figure 2 and Figure 3The sliding assembly includes two fixed rods 9 fixedly connected inside the U-shaped slide block 2. Each fixed rod 9 is rotatably connected to multiple rollers 10. The rollers 10 are in contact with the upper surface of the slide plate 1. The side walls of the slide plate 1 are provided with sliding grooves 11. The bottom of the side walls of the U-shaped slide block 2 are fixedly connected to sliders 12. The sliders 12 are slidably disposed in the sliding grooves 11. After the fixed tube 5 is moved out of the annular groove 8, the rollers 10 are moved on the slide plate 1 by pulling the pull plate 6, which drives the U-shaped slide block 2 to move. The sliding grooves 11 and sliders 12 work together to improve the stability of the U-shaped slide block 2 when it moves.

[0036] Reference Figure 1 The installation components include a discharge pipe 13 fixedly connected to the bottom of the hopper body 3. A solenoid valve for switching the discharge pipe 13 is installed on the discharge pipe 13. An installation plate 14 is fixedly connected to the bottom of the discharge pipe 13. Multiple first bolts 15 are provided on the upper surface of the installation plate 14. The first bolts 15 pass through the installation plate 14 and are threadedly connected to the U-shaped slide 2. The discharge pipe 13 is connected to the feed pipe 4. The installation plate 14 is fixedly connected to the U-shaped slide 2 by the first bolts 15, which facilitates the disassembly and installation of the hopper body 3.

[0037] Reference Figure 1 and Figure 2 The lower surface of the U-shaped slide 2 is fixedly connected to a plurality of annular array guide rods 16 on the outside of the feed tube 4. The top end of the fixed tube 5 is provided with a plurality of guide holes 17 that are adapted to the guide rods 16. The guide rods 16 are slidably disposed in the guide holes 17 respectively. Springs 27 are respectively sleeved on the guide rods 16. Through the guide rods 16 and the guide holes 17, the stability of the lifting and lowering of the fixed tube 5 can be improved and the springs 27 can be prevented from bending.

[0038] Reference Figure 1 Multiple support rods 18 are fixedly connected to the upper surface of the mounting plate 14. The top of the support rods 18 is fixedly connected to the hopper body 3.

The support rods 18 improve the stability of the hopper body 3. The cover plate 19 facilitates opening and closing of the hopper body 3. The viewing window 20 allows you to see the remaining material inside the hopper body 3.

[0039] Reference Figure 1 Positioning blocks 21 are fixedly connected to the two side walls of the slide plate 1 at both ends of the slide groove 11. When the U-shaped slide 2 is moved to both ends of the slide plate 1, the positioning blocks 21 prevent the U-shaped slide 2 from sliding out of the slide plate 1 and position the U-shaped slide 2 so that the feed pipe 4 is located directly above the feed port 7.

[0040] Reference Figure 1 and Figure 4The upper surface of the slide plate 1 is provided with second bolts 22 on the four sides of one of the discharge ports 7. The screw end of the second bolt 22 passes through the slide plate 1 and forms a sliding setting. The slide plate 1 can be easily fixed to the external injection molding machine by means of the second bolt 22, so that the discharge port 7 at this point is aligned with the feed port of the injection molding machine, and the material in the hopper body 3 is discharged into the injection molding machine.

[0041] Reference Figure 1 and Figure 4 The upper surface of the slide plate 1 is provided with multiple receiving holes 23. The nut end of the second bolt 22 is located in the receiving hole 23. The nut end of the second bolt 22 is hidden by the receiving hole 23 to prevent the second bolt 22 from extending on the upper surface of the slide plate 1 and affecting the sliding of the U-shaped slide block 2.

[0042] The implementation principle of the injection molding machine hopper moving mechanism in this embodiment is as follows: During use, the roller 10 rolls on the slide plate 1, driving the U-shaped slide 2 to move. The sliding groove 11 and the slider 12 improve the stability of the U-shaped slide 2 during movement. The U-shaped slide 2 slides on the slide plate 1, aligning the material tube 4 with one of the discharge ports 7. Then, by rotating the ring 24, the swing plate 6 is swung to move the T-shaped rod 26 out of the arc groove 25. Then, the pull plate 6 is released, and the spring 27 rebounds to push the fixing tube 5 downward and insert it into the annular groove 8 to prevent the U-shaped slide 2 from sliding. This avoids the problem of the material port slide lacking fixation, causing shaking during use, which can easily cause the hopper to move and reduce stability.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
