Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection stage center with a split-type adjustment structure and its injection molding machine. Background Technology

[0002] In the injection unit structure of an electric injection molding machine, the injection unit's center adjustment function is crucial to ensuring precise alignment between the nozzle center and the mold's injection hole, while the injection unit's rotation function facilitates screw replacement and maintenance. Currently, common injection unit structures integrate the center adjustment mechanism and the rotation mechanism, typically including vertical and horizontal adjustment bolts as well as fixing bolts for securing the injection unit's position. However, this integrated design has the following technical drawbacks:

[0003] 1. When adjusting the center position of the firing platform, it is necessary to first remove the fixing bolts of the front and rear seats of the firing platform, which increases the maintenance workload and affects production efficiency.

[0004] 2. Due to the high integration of the central adjustment mechanism and the rotating mechanism, the overall structure is compact but lacks flexibility, which limits the optimization space of the launcher design and makes it difficult to adapt to different working conditions.

[0005] 3. When the height of the firing platform is adjusted, the rotating shaft of the firing platform's rear seat and the corresponding mounting hole may become eccentric due to the change in height, resulting in increased rotational resistance or even jamming, which seriously affects the stability of the rotation function and its service life.

[0006] Therefore, the existing launcher structure has shortcomings in terms of ease of adjustment, structural flexibility, and rotational reliability. An improved solution is urgently needed to simplify the adjustment process, optimize the structural layout, and ensure the stable operation of the rotation function. Utility Model Content

[0008] This utility model provides a spray table center with a split adjustment structure, including a spray table center, a front support and a rear support. The injection end of the spray table center is rotatably connected to the upper end of the front support, and the rear end is rotatably connected to the upper end of the rear support. It also includes an adjustment structure for adjusting the height and horizontal position of the spray table center. The adjustment structure is located at the lower end of the front support and the rear support.

[0010] The front base is designed with two spaced-apart sections.

[0011] The adjusting shaft has an eccentric arrangement at its ends and middle; both ends of the adjusting shaft are rotatably connected to the front base, and the lower end of the front support is fixedly connected to the eccentric part in the middle of the adjusting shaft.

[0012] The rear base consists of two symmetrically spaced bases that are hinged to the lower end of the rear support.

[0013] The adjusting bolts are horizontally installed on the front and rear bases using a threaded connection, with their threaded ends abutting against the front and rear supports respectively.

[0014] Furthermore, the adjusting shaft is a coaxial cylindrical shape, with bushings fixed at both ends and eccentrically connected to the bushings; the bushings are inserted into the front base and fixedly connected.

[0015] Furthermore, an adjusting seat is fixedly connected to the lower end of the front support; the bushing is inserted into the adjusting seat and fixedly connected.

[0016] Furthermore, a pin is radially inserted between the bushing and the adjusting shaft.

[0017] Furthermore, the front base is composed of a first front support block and a second front support block arranged at intervals; an adjustment seat is disposed between the first front support block and the second front support block; both the first front support block and the second front support block on one side are threadedly connected with adjustment bolts; the threaded end of the adjustment bolt abuts against the adjustment seat.

[0018] Furthermore, a front hole is provided on the first front support block on one side; the drive bolt passes through the front hole and is fixedly connected to the adjusting shaft by means of threaded connection; the upper end of the first front support block is also provided with a front groove communicating with the front hole; the parts of the first front support block located on both sides of the front groove are respectively set as the front connecting part and the front fixing part; the locking bolt passes through the front connecting part and is threadedly connected to the front fixing part.

[0019] Furthermore, a hinge seat is fixedly connected to the lower end of the rear support; the hinge seat is hinged to the rear base through a hinge shaft; the rear base is composed of a first rear support block and a second rear support block arranged at intervals; both the first rear support block and the second rear support block on one side are threadedly connected with adjusting bolts; the threaded end of the adjusting bolt abuts against the hinge seat.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0038] Example 1:

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model discloses a launcher center with a split-type adjustment structure, including a launcher center, a front support 1 and a rear support 2. The injection end of the launcher center is rotatably connected to the upper end of the front support 1, and the rear end is rotatably connected to the upper end of the rear support 2.

[0040] This embodiment also includes an adjustment structure for adjusting the height and horizontal position of the center of the firing platform. The adjustment structure is located at the lower end of the front support 1 and the rear support 2.

[0041] The adjustment structure specifically includes a front base 3 and a rear base 5. A linear guide rail is installed on the upper end of the injection molding machine frame. The front base 3 and the rear base 5 are fixedly connected to the slider on the linear guide rail, allowing the center of the injection unit to slide on the frame, moving closer to or away from the mold.

[0042] like Figure 5 , Figure 7 and Figure 8 As shown, the front base 3 consists of two spaced-apart units connected by a rotating adjusting shaft 4. Along the axial direction of the adjusting shaft 4, the front base 3 comprises a first front support block 31 and a second front support block 32 arranged at intervals. An adjusting seat 8 is fixedly connected to the lower end of the front support 1 by bolts. A bushing 7, movably connected and located between the first and second front support blocks 31 and 32, is inserted into the adjusting seat 8. The adjusting shaft 4 is inserted into the bushing 7 and eccentrically connected to it. A pin 9 radially passes through the bushing 7 and the adjusting shaft 4, thus fixing the adjusting shaft 4 and the bushing 7 together. With this configuration, rotating the adjusting shaft 4 rotates the bushing 7, thereby adjusting the height of the front support 1 and the height of the center nozzle of the injection station under the eccentric connection between the bushing 7 and the adjusting shaft 4.

[0043] One end of the adjusting shaft 4 is also fixed with a drive bolt 13 by a threaded connection, so that the worker can drive the adjusting shaft 4 to rotate by turning the drive bolt 13.

[0044] To improve the positional stability of the drive bolt 13 after adjustment, such as Figure 2As shown, one of the first front support blocks 31 has a front hole 33; the drive bolt 13 passes through the front hole 33. The upper end of the first front support block 31 also has a front groove 34 communicating with the front hole 33; the portions of the first front support block 31 located on both sides of the front groove 34 are respectively designated as a front connecting portion 35 and a front fixing portion 36; the locking bolt 12 passes through the front connecting portion 35 and is threadedly connected to the front fixing portion 36. When the locking bolt 12 is tightened, the front groove 34 causes the front hole 33 to deform, clamping the drive bolt 13, which can improve the positional stability of the drive bolt 13. When the height of the nozzle at the center of the firing platform needs to be adjusted, first loosen the locking bolt 12. The pressure between the front hole 33 and the drive bolt 13 will disappear. Under the action of gravity, the thickest part of the bushing 7 will rotate freely to the lower end, so that the nozzle at the center of the firing platform is at the lowest point. In this way, you only need to turn the drive bolt 13 in the direction of locking the drive bolt 13 to adjust the height of the nozzle at the center of the firing platform upwards. You do not need to turn the drive bolt 13 in the opposite direction, which would cause the drive bolt 13 to loosen and lose its adjustment function.

[0045] On the same side as the drive bolt 13, the first front support block 31 and the second front support block 32 are each threadedly connected with an adjusting bolt 6, the threaded end of which abuts against the adjusting seat 8. This is used to adjust the horizontal position of the adjusting block, thereby adjusting the horizontal position of the center of the firing table. With this configuration, the operator can simultaneously adjust the height and horizontal position of the front support 1 without moving the position, thus simplifying the operation.

[0046] like Figure 6 , Figure 7 and Figure 9 As shown, the rear base 5 consists of two symmetrically spaced rear bases, hinged to the lower end of the rear support 2. Specifically, the lower end of the rear support 2 is fixedly connected to two hinge seats 10. The outer end of the hinge shaft 11 is rotatably connected to the rear base 5, and the inner end is fixedly connected to the hinge seat 10 through a profile connection. The rear base 5 is composed of a first rear support block 51 and a second rear support block 52 arranged at intervals; both the first rear support block 51 and the second rear support block 52 on the same side as the drive bolt 13 are threadedly connected to adjusting bolts 6; the threaded end of the adjusting bolt 6 abuts against the hinge seat 10 to adjust the horizontal position of the rear support 2.

[0047] Compared to existing technologies, the advantages of this embodiment are:

[0048] 1. By setting independent adjustment structures at the lower ends of the front support 1 and the rear support 2, the height and horizontal position of the firing platform center can be adjusted without disassembling the fixing bolts, which greatly simplifies the operation process, reduces the amount of maintenance work, and improves production efficiency.

[0049] 2. The design adopts a split design, separating the central adjustment mechanism from the rotating mechanism, avoiding the layout limitations caused by high integration, making the overall structure of the firing platform more flexible, easy to adapt to different working conditions, and providing more space for subsequent optimization design.

[0050] 3. The rear support 2 and the rear base 5 are hinged. The front support 1 is height-adjusted by the eccentric adjustment shaft 4 to ensure that the rotating shaft and the mounting hole are always aligned when the height of the shooting platform is adjusted, eliminating the rotational resistance or jamming caused by eccentricity, and ensuring the smoothness and long-term reliability of the rotation function.

[0051] 4. The adjusting bolt 6 is threaded and directly abuts against the support. Together with the mechanical structure of the eccentric adjusting shaft 4, it realizes fine adjustment and locking in one, ensuring that the center position of the injection stage is stably fixed after adjustment, and avoiding displacement caused by vibration during injection molding.

[0052] Example 2:

[0053] This utility model also discloses an injection molding machine, including a injection stage center with a split-type adjustment structure as described in Embodiment 1.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
