Description

Technical Field

[0001] The present invention relates to the technical field of shooting machines, and in particular to a rotating movement mechanism for a middle plate of a shooting machine and a use method thereof. Background Art

[0002] With the continuous development of injection molding technology, the market share of two-color injection molding machines has continued to increase. The promotion of multi-color plastic products has made multi-shot injection molding machines occupy an increasingly important position in the field of injection molding machines.

[0003] A double-shot machine is a type of multi-shot injection molding machine. By symmetrically placing two independent shot stations on either side of the clamping unit, it can simultaneously inject into two molds. The clamping unit of a double-shot machine is the core component that enables production. Based on a two-platen clamping structure, the clamping unit of a double-shot machine incorporates a center plate, which simultaneously clamps the two molds. After the first injection cycle is complete, the center plate is flipped over for the second injection cycle.

[0004] In the prior art, the movement of the center plate is typically achieved via a hydraulic cylinder, with movement and rotation designed separately. For example, Chinese patent document CN 110757720B discloses a multi-color injection molding machine comprising a frame, a fixed platen, a movable platen, a tie rod, a mold-shifting cylinder, and a shooting platform. The fixed platen is positioned at one end of the tie rod, the movable platen is sleeved onto the other end, and the mold-shifting cylinder is mounted on the frame, with its piston connected to the movable platen to drive its movement. The multi-color injection molding machine also includes a center plate and a center plate rotation mechanism. The center plate is fixed to the rotation mechanism and rotated by the rotation mechanism. Both sides of the center plate are used to mount molds. By using multiple shooting platforms, two products can be injected simultaneously during mold opening and closing, while the center plate can be rotated as needed to achieve multi-color injection.

[0005] However, the aforementioned technical solutions lack precise control during use, suffer from poor synchronization, and are complex and inconvenient to operate, preventing them from achieving an integrated modular design. Achieving precise movement and rotation of the center plate has become a crucial research topic for injection molding machines. Designing a center plate movement and rotation mechanism would not only achieve precise control of the center plate's movement and rotation, but also simplify the injection molding machine's structure and meet the requirements of an integrated, miniaturized modular design. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems in the prior art that the movement of the middle plate of the shooting machine is controlled by a cylinder, and the movement and rotation are carried out separately, the rotation accuracy cannot be precisely controlled, and the structure is complex and cannot meet the requirements of integrated and miniaturized module design. Instead, a rotation movement mechanism and a method for using the middle plate of the shooting machine are provided, which have a simple structure, good integration effect, convenient operation, synchronous translation and rotation, and high control accuracy. By modularly designing and combining the rotating platform and the linear module, precise control of the movement and rotation of the middle plate is achieved.

[0007] The technical solution adopted by the present invention to achieve its purpose is as follows: a rotary movement mechanism for the middle plate of a shooting machine, comprising a clamping body, on which a translation module and a rotation module capable of synchronous movement are integrated, the rotation module being integrated on the translation module and moving along the translation module, the translation module comprising a linear module and a screw transmission mechanism for driving the linear module to move synchronously; the rotation module comprising a rotary platform assembly slidably disposed on the linear module and a rotary platform driving mechanism for driving the rotary platform assembly to rotate. The rotary movement mechanism for the middle plate of the shooting machine is modularized through an integrated and modular design, wherein the mechanism for achieving linear movement of the middle plate and the mechanism for achieving rotation of the middle plate are modularized. At the same time, the translation module and the rotation module are integrated into a single clamping body, making the structure simpler. During use, the translation module and the rotation module can move synchronously or separately as needed, greatly saving mold opening and closing time and making operation more convenient. The translation module drives the linear module to move synchronously through a screw transmission mechanism, which can achieve precise control of the horizontal movement of the center plate. In addition, the translation module is used to independently realize the translation of the center plate, avoiding the problems of the existing technology of using a mold-moving cylinder for movement, complex sticks, and low control accuracy. At the same time, the center plate does not need to be guided with the pull rod during movement. The translation module can achieve smooth movement of the center plate, making the displacement adjustment of the center plate more flexible and able to meet the installation needs of more different molds. The rotation module uses a rotating platform drive mechanism to realize independent drive synchronous action, with high precision and good synergy. The rotary movement mechanism uses a translation module and a rotation module to realize the translation and rotation of the center plate, realizing automatic and precise movement and rotation control during the mold opening and closing process, saving production time and effectively improving production efficiency.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Example 1: In Figure 1, Figure 2 、 Figure 3 In the embodiment shown, a rotating movement mechanism for the middle plate of a shooting machine includes a clamping body 1, on which a translation module 2 and a rotation module 3 that can move synchronously are integrated. The rotation module 3 is integrated on the translation module 2 and moves along the translation module 2. The translation module 2 includes a linear module 6 and a screw transmission mechanism 7 that drives the linear module 6 to move synchronously; the rotation module 3 includes a rotating platform assembly 9 that is slidably arranged on the linear module 6 and a rotating platform driving mechanism 8 that drives the rotating platform assembly 9 to rotate.

[0037] The linear module 6 comprises two linear rail assemblies 4 and a base plate assembly 5 that moves along the linear rail assemblies 4 via a screw drive mechanism 7. Each linear rail assembly 4 is equipped with a ball screw 73. Both ball screws 73 are driven synchronously by the same drive motor 71 and the synchronous belt drive assembly. The ball screws 73 are flexibly connected to the synchronous belt drive assembly. Specifically, the ball screws 73 are flexibly connected to the synchronous belt drive assembly via a screw coupling 74.

[0038] The rotating platform assembly 9 includes a rotating base 91, and the rotating platform drive mechanism 8 includes a servo motor 81 and a gear transmission assembly. The gear transmission assembly is mounted on the rotating base 91 and is connected to the servo motor 81 via a flexible transmission. Specifically, the gear transmission assembly is connected to the servo motor output shaft via a platform drive coupling 82.

[0039] Ball screw 73 is flexibly connected to the synchronous belt drive assembly via a screw coupling 74. The gear drive assembly is connected to the servo motor output shaft via a platform drive coupling 82. This flexible connection and transmission via the coupling enables more precise coordinated motion. It also provides buffering and vibration reduction for translational and rotational power transmission, effectively reducing impact and vibration caused by operating condition changes or transmission imbalances, thereby lowering equipment vibration and noise. This provides excellent translational and rotational stability, high reliability, and extended service life.

[0040] The working principle of the middle plate rotation and movement mechanism is that the middle plate is fixed on the rotating platform assembly 9, and two molds are installed on both sides of the middle plate 20. The driving motor 71 drives the ball screw 73 on the linear module 6 to rotate through the synchronous belt 79, thereby driving the base plate assembly 5 to move. Since the rotating platform assembly 9 is connected to the base plate assembly 5, the rotating platform assembly 9 and the middle plate are moved. When the middle plate 20 moves to the appropriate position, the piston pull rod 30 drives the rear template 40 to close the mold. After the booster cylinder is pressurized, the front template 50 and the rear template 40 realize the locking of the mold. The locking action is completed, and the symmetrically distributed injection parts are injected. After the injection action is completed, the locking component opens the mold. After the middle plate completes the translation and rotation, the mold change action is completed, and another locking injection is performed to form a closed loop of action.

[0041] Through integrated and modular design, the mechanism for realizing the linear movement of the middle plate and the mechanism for realizing the rotation of the middle plate are modularly designed, and the translation module and the rotation module are integrated into a clamping machine body.

[0042] During use, the translation module and the rotation module can move synchronously or separately as needed. The translation module drives the linear module through a screw drive mechanism to achieve synchronous movement, enabling precise control of the horizontal movement of the center plate. Furthermore, the translation module independently realizes the translation of the center plate, avoiding the problems of the existing technology that uses a mold transfer cylinder for movement, which is complex and has low control accuracy.

[0043] The center platen does not require any guide rods during movement. The translation module allows for smooth movement of the center platen, making displacement adjustment more flexible and meeting the installation requirements of a wider range of molds. The rotation module utilizes a rotating platform drive mechanism to achieve independent drive and synchronous movement, resulting in high precision and effective synergy.

[0044] The translation module and the rotation module are used in conjunction to realize the translation and rotation of the middle plate, realizing automatic and precise movement and rotation control during the mold opening and closing process, saving production time and effectively improving production efficiency.

The rotation module 3 is integrated on the translation module 2 and moves along the translation module 2. The translation module 2 includes a linear module 6 and a screw transmission mechanism 7 that drives the linear module 6 to move synchronously; the rotation module 3 includes a rotating platform assembly 9 that is slidably arranged on the linear module 6 and a rotating platform driving mechanism 8 that drives the rotating platform assembly 9 to rotate.

[0046] The linear module 6 comprises two linear rail assemblies 4 and a base plate assembly 5 that moves along the linear rail assemblies 4 via a screw drive mechanism 7. Each linear rail assembly 4 is equipped with a ball screw 73. Both ball screws 73 are driven synchronously by a common drive motor 71 and a timing belt drive assembly. The ball screws 73 and the timing belt drive assembly are flexibly connected, specifically using a screw coupling 74 to flexibly connect to the timing belt drive assembly.

[0047] The rotating platform assembly 9 includes a rotating base 91, and the rotating platform drive mechanism 8 includes a servo motor 81 and a gear transmission assembly. The gear transmission assembly is mounted on the rotating base 91 and is connected to the servo motor 81 via a flexible connection. Specifically, the gear transmission assembly is connected to the servo motor output shaft via a platform drive coupling 82.

The inclined support platform 18 is fixedly connected to the inside of the fuselage frame 11, and the inclined support platform 11 tilts from one end of the horizontal support platform 17 to the other end to lower its height. A rotation module movement cavity L is positioned between the two horizontal support platforms 17. This space facilitates the translation of the rotation module along the linear module. A platform spacing H is provided between the horizontal support platform 17 and the inclined support platform 18. This spacing facilitates the installation and movement of the rotation module. A motor installation space 16 is provided between the horizontal support platform 17 and the end surface of the fuselage frame 11. Rear template support legs 10 are positioned at the end of the fuselage frame 11 where the motor installation space 10 is located. Front template support legs 101 are positioned at the other end of the fuselage frame 11.

[0052] like Figure 5 、 Figure 6 As shown, the linear module 6 includes two sets of linear rail assemblies 4 and a base plate assembly 5 that are symmetrically arranged. The linear rail assembly 4 includes a module base plate 41, a module linear rail 42 arranged on the module base plate 41, and a module slider 43 that is slidably connected to the module linear rail 42.

[0053] Each set of linear rail assemblies 4 includes a module base plate 41 , a module linear rail 42 arranged on the module base plate 41 , and a module slider 43 slidably connected to the module linear rail 42 . The two sets of linear modules 6 are synchronously driven to rotate through a set of screw transmission mechanisms 7 .

[0054] The module base plate 41 is a U-shaped groove plate structure with a base plate groove 411 and a base plate side wall 412. The module linear rail 42 is arranged on the upper end surface of the base plate side wall 412 along the length direction, and the screw transmission mechanism 7 is arranged at the bottom of the base plate groove 411.

[0055] The screw transmission mechanism 7 includes a drive motor 71, a ball screw 73 arranged parallel to the module linear rail 42, and a synchronous belt transmission assembly arranged between the drive motor and the ball screw.

[0057] Specifically, the screw transmission mechanism 7 includes a drive motor 71, a ball screw support seat 72, and a ball screw 73 rotatably mounted on the ball screw support seat 72. The ball screw support seats 72 are disposed at both ends of the bottom plate groove 411. One end of the ball screw 73 is connected to a screw coupling 74. A screw drive pulley shaft 75 is connected to the screw coupling 74. A driven pulley 76 is disposed on the screw drive pulley shaft 75.

[0058] The drive motor 71 is mounted within the motor mounting space 16 via a motor bracket 77. The output shaft of the drive motor 71 is positioned parallel to the ball screws 73 and positioned between the two sets of ball screws 73. The motor mounting bracket 77 is provided with a motor shaft hole, through which the output shaft of the drive motor 71 extends into the interior of the motor mounting bracket 77. A driving pulley 78 is provided on the output shaft of the drive motor, and a synchronous belt 79 is wound around the driving pulley 78 and the driven pulley 76. The rotation of the drive motor drives the rotation of the driving pulley, which in turn drives the rotation of the two driven pulleys via the synchronous belt, thereby driving the synchronous rotation of the two ball screws.

[0059] During assembly, the module linear rail 42 is symmetrically mounted on the module base plate 41 and secured with screws. Ball screw support seats 72 are installed at both ends of the base plate slot of the module base plate 41. The ball screw 73 is rotatably mounted on the ball screw support seat 73. A screw transmission mechanism support seat 70 is installed on the outer end of the ball screw support seat 73 at one end. The screw coupling 74 is connected to the ball screw 73. After installation, the module slider 43 is installed on the module linear rail 42.

[0060] The function of the linear module 6 is to drive the ball screw 73 to rotate under the action of the drive motor 71 and the synchronous belt 79, and further drive the module slider 43 to move. Since the module slider 43 is connected to the base plate assembly 5, the base plate assembly 5 can be translated.

[0061] like Figure 7 As shown, the base plate assembly 5 includes a symmetrically arranged set of guide rails 51, guide rail sliders 52 slidably mounted on the guide rails 51, and a base plate 53 fixed to the guide rail sliders 52. The base plate 53 is also fixedly connected to the module slider 43 and is driven by the module slider 73 to move simultaneously along the module linear rails 42 and the guide rails 51. The base plate 53 is provided with a driver mounting slot 54.

[0062] The assembly process of the base plate assembly 5 is as follows: the guide rail 51 is fixed to the base plate assembly support platform 13 of the clamping body 1, the guide rail slider 52 is installed on the guide rail 51, and the base plate 53 and the guide rail slider 52 are connected with screws. The function of the base plate assembly 5 is to complete the connection between the lower end linear module 6 and the upper end rotary module 3.

[0063] like Figure 8 、 Figure 9 As shown, the rotating module 3 includes a rotating platform driving mechanism 8 and a rotating platform assembly 9 driven to rotate by the rotating platform driving mechanism 8 .

[0064] The rotating platform assembly 9 includes a rotating base 91, a connecting plate 92, and a wear-resistant plate 93. The rotating base 91 is provided with a base annular cavity 95 and a transmission seat 96. Gear meshing transmission holes 97 are opened in the base annular cavity 95 corresponding to the transmission seat 96. Specifically, the rotating base 91 includes an integrally provided base connecting plate 94 and a base annular cavity 95. The transmission seat 96 is provided on the base connecting plate 94, and gear meshing transmission holes 97 are opened in the base annular cavity 95 corresponding to the transmission seat 96.

[0065] The rotating platform driving mechanism 8 includes a servo motor 81 and a gear transmission assembly.

[0066] The gear transmission assembly includes a driving gear 84 and a large ring gear 85 arranged inside the base ring cavity 95. The driving gear 84 and the large ring gear 85 are engaged at the gear meshing transmission hole 97; the driving gear 84 is set on a rotating shaft 83, and the rotating shaft 83 is connected to the output shaft of the servo motor through a platform drive coupling.

[0067] Specifically, the platform drives the shaft 83 connected to the output shaft of the servo motor through the coupling 82, the driving gear 84 on the shaft 83, and the large ring gear 85 inside the base ring cavity 95. The driving gear 84 and the large ring gear 85 are engaged at the gear engagement transmission hole 97.

[0068] The rotating platform driving mechanism 8 is arranged at the bottom of the rotating base 91 through a driving mechanism bracket 86 .

[0069] The assembly process of the rotating module 3 is as follows: fix the drive mechanism bracket 86 to the bottom of the rotating base 91, and use screws to install the servo motor 81 on the drive mechanism bracket 86. One end of the platform drive coupling 82 is connected to the output shaft of the servo motor 81, and the other end is connected to the rotating shaft 83. The drive gear 84 is fixed on the rotating shaft 83. Three sets of transition wheels 87 are evenly installed at the bottom of the base ring cavity 95 of the rotating base 91. The function of the transition wheel 87 is to provide a fulcrum for the rotation of the large ring gear 85. After installing the large ring gear 85, use screws to fix the connecting plate 94 on the large ring gear 85, and place a wear-resistant plate 93 above the connecting plate 85. The rotating platform assembly 9 drives the drive gear 84 to rotate through the servo motor 81. The drive gear 84 engages with the large ring gear 85, thereby driving the large ring gear 85 to rotate together. The large ring gear 85 rotates and drives the connecting plate 92 and the wear-resistant plate 93 fixed to it to rotate together.

[0070] The installation process for the center plate rotation mechanism is as follows: Secure the clamping body 1 and symmetrically install the two linear modules 6 inside the clamping body 1. Once installed, place the base plate assembly 5 on the clamping body 1 and screw the module linear rails 42 to the clamping body 1. Simultaneously, screw the module sliders 43 of the already installed linear modules 6 to the base plate assembly 5. Install the motor bracket 77 and drive motor 71 at the front end of the clamping body 1. Use a synchronous belt 79 to drive the two linear modules 6 to complete linear movement. This completes the installation of the translation module 2.

[0071] Next, install the rotating module 3, align the rotating platform assembly 9 and place it above the base assembly 5. The servo motor 81 needs to be nested in the drive component mounting slot 54 of the base assembly. Use screws to connect the rotating platform assembly 9 to the base assembly 5, and install the middle plate 20 on the rotating platform assembly 9. The rotating module is now complete.

[0072] Example 3: like Figure 10 、 Figure 11 As shown, a method for using a rotating movement mechanism for a mid-plate of a shooting machine includes the following steps: S1: Fix the middle plate on the rotating platform assembly and install two molds on both sides of the middle plate; S2: The screw transmission mechanism drives the ball screw to rotate, driving the module slider 3 to move, driving the base plate assembly to move synchronously along the module linear rail and guide rail, so that the middle plate moves linearly; S3: When the middle plate moves into place, the mold is closed, locked and injection is performed; S4: Open the mold, the translation module and the rotation module move, the middle plate translates and rotates, the mold change is completed, and the mold is locked and injected again to form a closed loop of action.

[0073] Specifically, the middle plate is fixed on the rotating platform assembly 9, and two molds are installed on both sides of the middle plate 20. The driving motor 71 drives the ball screw 73 on the linear module 6 to rotate through the synchronous belt 79, driving the module slider 43 to move. Since the module slider 43 is connected to the bottom plate 53 on the bottom plate assembly 5 by screws, the rotating platform assembly 9 and the middle plate are moved. When the middle plate 20 moves to the appropriate position, the piston pull rod 30 drives the rear template 40 to close the mold. After the booster cylinder is pressurized, the front template 50 and the rear template 40 realize the locking of the mold. The locking action is completed, and the symmetrically distributed injection parts are injected. After the injection action is completed, the locking component opens the mold. After the middle plate completes the translation and rotation, the mold change action is completed, and the locking injection is performed again to form a closed action loop.
