[0006] In use, this invention features a connecting block with a conical groove extending in the front-to-back direction. A truncated cone is coaxially positioned within the groove, with its smaller diameter end facing the same direction as the smaller diameter end of the conical groove. A feeding device connected to the smaller diameter end of the conical groove is mounted on the front wall of the connecting block. An annular groove, closed circumferentially and coaxial with the truncated cone, is located on the rear wall of the connecting block. The inner diameter of the annular groove lies between the inner diameters of the smaller and larger diameter ends of the conical groove. The bottom of the annular groove extends laterally into the connecting block towards the smaller diameter end of the conical groove. A conical cone is slidably positioned within the annular groove. The tapered tube has the same slope as the inner wall of the tapered groove. The small diameter end of the tapered tube faces the same direction as the small diameter end of the truncated cone. A connecting plate is fixed to the large diameter end of the tapered tube on the side wall of the truncated cone away from the small diameter end of the tapered groove. A vertical plate is installed on the side wall of the connecting block away from the feeding device. A driving mechanism is provided on the vertical plate to move the connecting plate back and forth within the connecting block. A groove adapted to the connecting plate is opened on the side wall of the vertical plate facing the truncated cone. The side wall of the connecting plate facing the truncated cone abuts against the end of the tapered groove away from the feeding device. When the device is in use, the feeding device... The material is fed into the connecting block through the small-diameter opening of the conical groove, allowing it to enter between the truncated cone, connecting plate, and conical groove for bottle injection molding. To adjust the bottle wall thickness, the drive mechanism can be controlled to move the connecting plate away from the feeding device within the connecting block, positioning it in a groove on the vertical plate. This movement also causes the conical tube to move away from the feeding device within the annular groove, aligning the end of the conical tube away from the feeding device with the sidewall of the connecting block away from the feeding device, and aligning the inner sidewall of the conical tube with the conical groove. The inner wall is connected at the end away from the feeding device. Then, the feeding device feeds the material into the connecting block through the small diameter opening of the conical groove. This allows the material to enter between the truncated cone, the connecting plate, and the conical groove for the injection molding of the bottle. After the bottle is injection molded, the vertical plate is removed from the connecting block. By controlling the movement of the vertical plate, the connecting plate, the conical tube, and the truncated cone are separated from the connecting block, allowing the injection-molded bottle to be removed from the connecting block. This not only makes it convenient for workers to perform the injection molding operation on the bottle but also makes it easier for workers to adjust the wall thickness of the injection-molded bottle.

[0007] Preferably, the driving mechanism includes a threaded hole and a sliding hole on the side wall of the truncated cone away from the feeding device. A threaded rod is provided in the threaded hole. The threaded rod extends through the connecting plate and the vertical plate in the direction away from the feeding device to the side of the vertical plate away from the truncated cone. A limit rod is provided in the sliding hole. The limit rod extends through the connecting plate in the direction away from the feeding device and is fixed to the bottom of the groove. The threaded rod is rotatably connected to the vertical plate. The driving mechanism includes a threaded hole and a sliding hole on the side wall of the truncated cone away from the feeding device. A threaded rod is installed in the threaded hole, extending through the connecting plate and the vertical plate away from the feeding device to the side of the vertical plate away from the truncated cone. A limit rod is installed in the sliding hole, extending through the connecting plate away from the feeding device and fixed to the bottom of the groove. When the device is in use, by rotating the threaded rod, the threaded rod rotates in the threaded hole on the vertical plate, the connecting plate and the truncated cone. At this time, because one end of the limit rod is located in the truncated cone and the other end of the limit rod is fixed to the bottom of the groove, the truncated cone will not rotate with the threaded rod, but will move away from the feeding device under the rotation drive of the threaded rod. This causes the connecting plate to move away from the feeding device in the connecting block, so that the connecting plate enters the groove on the vertical plate.

[0008] Preferably, the annular groove has a circumferentially closed annular groove on the side wall facing the feeding device. The inner diameter of the annular groove is the same as the inner diameter of the annular slide. An annular plate is installed inside the annular groove and is fixedly connected to the side wall facing the feeding device of the conical tube. By having a circumferentially closed annular groove on the side wall facing the feeding device, with the inner diameter of the annular groove matching the inner diameter of the annular slide, and an annular plate fixedly connected to the side wall facing the feeding device of the conical tube, the connection between the end of the inner wall of the conical tube facing the feeding device and the end of the inner wall of the conical groove away from the feeding device can be blocked and sealed. This prevents material from entering the annular groove when the feeding device injects material into the space between the truncated cone, connecting plate, and conical groove to mold the bottle, thus avoiding interference with the normal operation of the device.

[0009] Preferably, the threaded rod is coaxially arranged with the truncated cone. By arranging the threaded rod and the truncated cone coaxially, it is convenient for the operator to drive the truncated cone to move within the connecting block.

[0010] Preferably, two limiting rods are provided, with the two limiting rods located on the upper and lower sides of the threaded rod, respectively. By providing two limiting rods and positioning them on the upper and lower sides of the threaded rod, the stability of the device during use can be improved.

[0011] Preferably, a rotating handle is fixedly connected to the end of the threaded rod away from the feeding device. By fixing a rotating handle to the end of the threaded rod away from the feeding device, the operator can easily rotate the threaded rod using the rotating handle.

[0012] The beneficial effects of this utility model are as follows: By setting a connecting block, a conical groove extending in the front-to-back direction is provided on the connecting block. A truncated cone is coaxially arranged in the conical groove, and the small diameter end of the truncated cone faces the same direction as the small diameter end of the conical groove. A feeding device communicating with the small diameter end of the conical groove is installed on the front side wall of the connecting block. An annular sliding groove that is circumferentially closed and coaxial with the truncated cone is provided on the rear side wall of the connecting block. The inner diameter of the annular sliding groove is between the inner diameters of the small and large diameter ends of the conical groove. The bottom of the annular sliding groove extends laterally into the connecting block towards the small diameter end of the conical groove. A conical... The tapered tube has the same slope as the inner wall of the tapered groove. The small diameter end of the tapered tube faces the same direction as the small diameter end of the truncated cone. A connecting plate is fixed to the large diameter end of the tapered tube on the side wall of the truncated cone away from the small diameter end of the tapered groove. A vertical plate is installed on the side wall of the connecting block away from the feeding device. A driving mechanism is provided on the vertical plate to move the connecting plate back and forth within the connecting block. A groove adapted to the connecting plate is opened on the side wall of the vertical plate facing the truncated cone. The side wall of the connecting plate facing the truncated cone abuts against the end of the tapered groove away from the feeding device. When the device is in use, the feeding device... The material is fed into the connecting block through the small-diameter opening of the conical groove, allowing it to enter between the truncated cone, connecting plate, and conical groove for bottle injection molding. To adjust the bottle wall thickness, the drive mechanism can be controlled to move the connecting plate away from the feeding device within the connecting block, positioning it in a groove on the vertical plate. This movement also causes the conical tube to move away from the feeding device within the annular groove, aligning the end of the conical tube away from the feeding device with the sidewall of the connecting block away from the feeding device, and aligning the inner sidewall of the conical tube with the conical groove. The inner wall is connected at the end away from the feeding device. Then, the feeding device feeds the material into the connecting block through the small diameter opening of the conical groove. This allows the material to enter between the truncated cone, the connecting plate, and the conical groove for the injection molding of the bottle. After the bottle is injection molded, the vertical plate is removed from the connecting block. By controlling the movement of the vertical plate, the connecting plate, the conical tube, and the truncated cone are separated from the connecting block, allowing the injection-molded bottle to be removed from the connecting block. This not only makes it convenient for workers to perform the injection molding operation on the bottle but also makes it easier for workers to adjust the wall thickness of the injection-molded bottle.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figures 1-3 The plastic bottle injection molding device of this utility model includes a connecting block 2. A conical groove 10 extending in the front-to-back direction is provided on the connecting block 2. A truncated cone 12 is coaxially arranged within the conical groove 10. The small-diameter end of the truncated cone 12 faces the same direction as the small-diameter end of the conical groove 10. A feeding device 3 connected to the small-diameter end of the conical groove 10 is installed on the front sidewall of the connecting block 2. An annular groove 8, closed circumferentially and coaxial with the truncated cone 12, is provided on the rear sidewall of the connecting block 2. The inner diameter of the annular groove 8 is between the inner diameters of the small and large diameter ends of the conical groove 10. The bottom of the annular groove 8 extends laterally towards the small-diameter end of the conical groove 10 into the connecting block 2. The annular groove 8 allows for sliding within it. A tapered tube 9 is provided, the inner sidewall of which has the same slope as the inner sidewall of the tapered through groove 10. The small diameter end of the tapered tube 9 faces the same direction as the small diameter end of the truncated cone 12. A connecting plate 11 is provided on the sidewall of the truncated cone 12 away from the small diameter end of the tapered through groove 10, which is fixed to the sidewall of the large diameter end of the tapered tube 9. A vertical plate 5 is installed on the sidewall of the connecting block 2 away from the feeding device 3. A driving mechanism is provided on the vertical plate 5 to move the connecting plate 11 back and forth within the connecting block 2. A groove 6 adapted to the connecting plate 11 is opened on the sidewall of the vertical plate 5 facing the truncated cone 12. The sidewall of the connecting plate 11 facing the truncated cone 12 abuts against the end of the tapered through groove 10 away from the feeding device 3.

[0020] The driving mechanism includes a threaded hole 16 and a sliding hole 15 on the side wall of the truncated cone 12 away from the feeding device 3. A threaded rod 4 is provided in the threaded hole 16. The threaded rod 4 extends through the connecting plate 11 and the vertical plate 5 in the direction away from the feeding device 3 to the side of the vertical plate 5 away from the truncated cone 12. A limiting rod 7 is provided in the sliding hole 15. The limiting rod 7 extends through the connecting plate 11 in the direction away from the feeding device 3 and is fixed to the bottom of the groove 6. When the device is in use, by rotating the threaded rod 4, the threaded rod 4 rotates in the threaded hole 16 on the vertical plate 5, the connecting plate 11 and the truncated cone 12. At this time, because one end of the limiting rod 7 is located in the truncated cone 12 and the other end of the limiting rod 7 is fixed to the bottom of the groove 6, the truncated cone 12 will not rotate with the threaded rod 4. Instead, it will move in the direction away from the feeding device 3 under the rotation drive of the threaded rod 4. This causes the connecting plate 11 to move in the connecting block 2 in the direction away from the feeding device 3, so that the connecting plate 11 enters the groove 6 on the vertical plate 5. An annular groove 13, which is circumferentially closed, is provided on the side wall of the annular chute 8 facing the feeding device 3. The inner diameter of the annular groove 13 is the same as that of the annular chute 8. An annular plate 14, which is fixed to the side wall of the conical tube 9 facing the feeding device 3, is provided in the annular groove 13. The annular plate 14 can block and seal the connection between the end of the inner wall of the conical tube 9 facing the feeding device 3 and the end of the inner wall of the conical channel 10 away from the feeding device 3, so as to prevent the material from entering the annular chute 8 when the feeding device 3 injects the material into the space between the conical truncated cone 12, the connecting plate 11 and the conical channel 10 to injection mold the bottle, thus preventing the material from affecting the normal use of the device. By setting the threaded rod 4 coaxially with the conical truncated cone 12, it is convenient for the operator to drive the conical truncated cone 12 to move within the connecting block 2. By setting two limiting rods 7 and placing the two limiting rods 7 on the upper and lower sides of the threaded rod 4 respectively, the stability of the device during use can be improved. By fixing a rotating handle 1 to the end of the threaded rod 4 away from the feeding device 3, the operator can easily rotate the threaded rod 4 using the rotating handle 1.

[0021] Combined with appendix Figures 1-3As can be seen, the method of using this utility model is as follows: First, the material is fed into the connecting block 2 through the small-diameter end opening of the conical groove 10 by the feeding device 3, so that the material enters between the truncated cone 12, the connecting plate 11 and the conical groove 10 for the injection molding of the bottle. If it is desired to adjust the wall thickness of the injection molded bottle, the threaded rod 4 is rotated by controlling the rotating handle 1, so that the threaded rod 4 rotates in the threaded hole 16 on the vertical plate 5, the connecting plate 11 and the truncated cone 12. At this time, because one end of the limiting rod 7 is located on the truncated cone 12, the material is used to inject the material into the bottle. Inside the 2nd section, the other end of the limiting rod 7 is fixedly connected to the bottom of the groove 6. Therefore, the truncated cone 12 will not rotate with the threaded rod 4, but will move away from the feeding device 3 under the rotation drive of the threaded rod 4. This causes the connecting plate 11 to move away from the feeding device 3 within the connecting block 2, so that the connecting plate 11 enters the groove 6 on the vertical plate 5, and drives the tapered tube 9 to move away from the feeding device 3 within the annular slide groove 8. This causes the end of the tapered tube 9 away from the feeding device 3 to be connected to the connecting block 2 away from the feeding device. 3. With one side wall aligned, the inner wall of the conical tube 9 facing the feeding device 3 is connected to the inner wall of the conical groove 10 away from the feeding device 3. The annular plate 14 moves with the conical tube 9 and disengages from the annular groove 13. The annular plate 14 then blocks and seals the connection between the inner wall of the conical tube 9 facing the feeding device 3 and the inner wall of the conical groove 10 away from the feeding device 3, preventing the feeding device 3 from impacting the bottle body when injecting material into the conical truncated cone 12, connecting plate 11, and conical groove 10. During injection molding, the material enters the annular chute 8, and then the feeding device 3 feeds the material through the small diameter end opening of the conical through groove 10 into the connecting block 2. This allows the material to enter between the truncated cone 12, the connecting plate 11, and the conical through groove 10 for the injection molding of the bottle. After the bottle is injection molded, the vertical plate 5 is removed from the connecting block 2, and the vertical plate 5 is moved by controlling it to separate the connecting plate 11, the conical tube 9, and the truncated cone 12 from the connecting block 2, thereby removing the injection-molded bottle from the connecting block 2.
