Description

Technical Field

[0001] This utility model relates to the field of injection molded part removal, specifically an injection molding part removal machine. Background Technology

[0002] Injection molding part removal machine, or simply injection molding part remover, is an automated device that uses a robotic arm to automatically, precisely, and efficiently remove molded plastic parts from the mold and place them in a designated location. Its core function is to replace manual part removal, significantly improving production efficiency, ensuring operational safety, and guaranteeing production continuity and product consistency. It is an indispensable supporting device in modern injection molding production.

[0003] In existing injection molding removal machines, the robotic arm base is fixed to the ground with bolts during use. However, in actual use, it is impossible to fine-tune the installation angle of the robotic arm. When there is a slight deviation in the position of the injection molding mold, the base needs to be disassembled and adjusted again, which is cumbersome. Therefore, the inventor urgently needs to design a device that can change the installation angle of the robotic arm to improve its applicability. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a part removal machine for injection molding machines to solve the technical problem of low applicability of robotic arm installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a part removal machine for injection molding machines, comprising a robotic arm base, a support plate disposed below the robotic arm base, the interior of the support plate being a T-shaped groove, slide rails disposed on both sides of the T-shaped groove, a turntable fixedly connected below the robotic arm base, a ring of gear teeth disposed on the outer circumference of the turntable, a movable plate rotatably connected below the turntable, a drive mechanism disposed on one side of the movable plate, a first motor disposed on the other side of the movable plate, the first motor being electrically connected to an external power supply via a controller, and a gear connected to the upper output end of the first motor.

[0006] By adopting the above technical solution, a double-layer adjustment structure of turntable and movable plate is integrated under the base of the robotic arm, realizing independent control of the translation and rotation of the robotic arm. When there is a deviation in the position of the injection molding mold, there is no need to disassemble the base bolts, and the position and angle errors can be compensated directly by the two sets of drive systems respectively.

[0007] Furthermore, the movable plate is slidably connected to the slide rail via sliders on both sides.

[0008] By adopting the above technical solution, the movable plate is slidably connected to the slide rail on both sides, creating a high-rigidity, low-friction translation mechanism. This structure can effectively resist the lateral force brought by the impact of the injection molding machine's mold closing, and prevent the movable plate from deforming or jamming during long-term use.

[0009] Furthermore, the gear meshes with the teeth of the turntable, and the first motor drives the gear to rotate, thereby causing the turntable to rotate.

[0010] By adopting the above technical solution and using a transmission scheme in which gears directly mesh with the outer ring teeth of the turntable, the robot arm angle adjustment has precise digital control capabilities. The circumferential thrust generated when the first motor drives the gear is evenly distributed on the entire turntable gear ring, completely avoiding the risk of base deformation caused by traditional single-point jacking with bolts.

[0011] Furthermore, the drive mechanism includes an oil tank body, and an oil filling port is provided on the top of the oil tank body.

[0012] By adopting the above technical solution, the integrated design of the oil tank and the oil inlet significantly improves the sealing reliability and maintenance convenience of the hydraulic system. The oil tank adopts a fully enclosed structure, which effectively isolates external dust and moisture from contaminating the hydraulic oil, thus preventing system failure caused by oil deterioration from the source.

[0013] Furthermore, a second motor is connected to the upper side of the oil tank via a flange, and the second motor is electrically connected to an external power source via a controller.

[0014] By adopting the above technical solution, the design of directly connecting the second motor to the oil tank via the flange creates a highly efficient and vibration-resistant power transmission structure. The rigid connection characteristics of the flange completely eliminate the transmission gap between the motor and the pump body, ensuring that the hydraulic pump can still output pressure oil stably under the high-frequency vibration environment of the injection molding machine.

[0015] Furthermore, a hydraulic cylinder is provided on one side below the oil tank body, and one end of the hydraulic cylinder is connected to a piston rod.

[0016] By adopting the above technical solution, the side-mounted layout of the cylinder and piston rod optimizes the mechanical efficiency of the thrust transmission path. The cylinder is horizontally installed on the side of the oil tank, so that the extension and retraction direction of the piston rod is completely parallel to the moving axis of the movable plate, avoiding additional friction loss caused by oblique force.

[0017] Furthermore, a connecting ring is provided at one end of the piston rod, and a pull ring is provided on one side of the movable plate, with the connecting ring and the pull ring being fastened together.

[0018] By adopting the above technical solution, the modular snap-fit ​​structure of the connecting ring and the pull ring provides a force transmission interface that balances reliability and flexibility. The slot of the connecting ring and the cylindrical pin of the pull ring form a self-locking fit, which can maintain mechanical engagement even if the hydraulic system suddenly depressurizes, preventing the moving plate from accidentally retracting.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model overcomes the rigid constraints of traditional fixed bases by providing a robotic arm adjustment mechanism. The movable plate achieves overall translation of the robotic arm through the sliding connection between the T-slot slide rail and the support plate. The hydraulic drive mechanism pushes the piston rod to drive the movable plate to move linearly. This structure can compensate for the installation position deviation between the injection molding machine and the robotic arm without disassembling the bolts. At the same time, the rotational connection between the turntable and the base, combined with the gear transmission mechanism, enables the first motor to drive the gear to mesh with the turntable's outer gear ring to generate precise rotation, directly changing the installation angle of the robotic arm.

[0021] 2. This utility model uses two sets of adjustment systems that operate independently and do not interfere with each other. The hydraulic drive unit provides linear displacement power through the extension and retraction of the cylinder piston rod. The snap-fit ​​design between its connecting ring and the movable plate pull ring automatically reduces vibration energy when transmitting thrust. The motor and gear unit control the rotation accuracy through tooth meshing, eliminating the risk of angle drift in traditional adjustment methods. This design greatly reduces the downtime adjustment time caused by mold position deviation, and improves the applicability and overall utilization rate of production line equipment.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] An injection molding machine part removal machine, such as Figure 1-4 As shown, the system includes a robotic arm base 1, a support plate 2 below the robotic arm base 1, a T-shaped groove 201 inside the support plate 2, and slide rails 202 on both sides of the T-shaped groove 201. A turntable 3 is fixedly connected to the bottom of the robotic arm base 1, and a ring of teeth is provided on the outer ring of the turntable 3. A movable plate 4 is rotatably connected to the bottom of the turntable 3. A drive mechanism 8 is provided on one side of the movable plate 4, and a first motor 5 is provided on the other side of the movable plate 4. The first motor 5 is electrically connected to an external power source through a controller, and the upper output terminal of the first motor 5 is connected to... With gear 6, a double-layer adjustment structure integrating turntable 3 and movable plate 4 is integrated below the base 1 of the robotic arm, realizing independent control of the translation and rotation of the robotic arm. When there is a deviation in the position of the injection molding mold, there is no need to disassemble the base bolts. The position and angle errors can be compensated directly by the two sets of drive systems respectively. At the same time, the nested design of T-slot 201 and slide rail 202 provides a stable linear guide foundation for the movable plate, ensuring that the robotic arm as a whole does not tilt or vibrate during the translation process, which significantly improves the positioning accuracy and success rate when the injection molded part is taken out.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The movable plate 4 is slidably connected to the slide rail 202 via sliders on both sides. This slidable connection creates a high-rigidity, low-friction translation mechanism. This structure can effectively resist the lateral force brought by the impact of the injection molding machine's mold closing, and prevent the movable plate from deforming or jamming during long-term use. At the same time, the closed track design of the T-slot can prevent workshop dust and plastic debris from entering the slide rail, greatly reducing the frequency of equipment maintenance. The modularity of the sliders enables the entire translation unit to be quickly replaced, significantly shortening the downtime caused by component wear.

[0031] See Figure 2 , Figure 3 , Figure 4Gear 6 meshes with the teeth of turntable 3. The first motor 5 drives gear 6 to rotate, which in turn drives turntable 3 to rotate. The transmission scheme in which gear 6 directly meshes with the outer ring teeth of turntable 3 enables precise digital control of the robot arm angle adjustment. The circumferential thrust generated when the first motor 5 drives the gear is evenly distributed on the entire turntable gear ring, which completely avoids the risk of base deformation caused by traditional single-point pushing with bolts. At the same time, the forced meshing characteristics of the gear pair can automatically eliminate the turntable rotation gap, ensuring that the robot arm will not drift in angle due to inertia during high-speed picking, and fully guaranteeing the repeatability and positioning accuracy of the picking trajectory.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The drive mechanism 8 includes an oil tank 801, with an oil inlet 802 located on top of the oil tank 801. The integrated design of the oil tank 801 and the oil inlet 802 significantly improves the sealing reliability and maintenance convenience of the hydraulic system. The oil tank adopts a fully enclosed structure, effectively isolating external dust and moisture from contaminating the hydraulic oil, thus preventing system failure caused by oil deterioration from the source. At the same time, the layout of the top oil inlet allows for oil replenishment without disassembling the equipment casing or moving parts. Maintenance personnel can directly monitor and replenish the oil level from above the equipment, greatly reducing the risk of cylinder jamming caused by insufficient lubrication and extending the service life of the drive mechanism.

[0033] See Figure 1 , Figure 3 , Figure 4 A second motor 804 is connected to the upper side of the oil tank 801 via a flange 803. The second motor 804 is electrically connected to an external power source via a controller. The design of the flange 803 directly connecting the second motor 804 to the oil tank 801 creates an efficient and vibration-resistant power transmission structure. The rigid connection characteristic of the flange completely eliminates the transmission gap between the motor and the pump body, ensuring that the hydraulic pump can still output pressure oil stably under the high-frequency vibration environment of the injection molding machine. At the same time, this compact integrated solution reduces the energy loss of traditional belt or coupling transmission, enabling the motor power to be converted into hydraulic energy with almost no loss, significantly improving the system response speed and providing instant driving force for the translation of the movable plate.

[0034] See Figure 1 , Figure 3 , Figure 4A hydraulic cylinder 805 is installed on one side below the oil tank body 801. One end of the hydraulic cylinder 805 is connected to a piston rod 806. The side-mounted layout of the hydraulic cylinder 805 and the piston rod 806 optimizes the mechanical efficiency of the thrust transmission path. The hydraulic cylinder is installed horizontally on the side of the oil tank body, so that the extension and retraction direction of the piston rod is completely parallel to the moving axis of the movable plate, avoiding additional friction loss caused by oblique force. At the same time, the short-channel connection design between the hydraulic cylinder and the oil tank minimizes the pressure loss of the hydraulic pipeline, ensuring that the piston rod can output stable thrust throughout the entire stroke range, effectively overcoming the starting inertia force of the movable plate under heavy load conditions, and realizing smooth movement of continuously variable transmission.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A connecting ring 807 is provided at one end of the piston rod 806, and a pull ring 7 is provided on one side of the movable plate 4. The connecting ring 807 and the pull ring 7 are interlocked. The modular interlocking structure of the connecting ring 807 and the pull ring 7 provides a force transmission interface that balances reliability and flexibility. The groove of the connecting ring and the cylindrical pin of the pull ring form a self-locking fit. Even if the hydraulic system suddenly depressurizes, it can still maintain mechanical engagement and prevent the movable plate from accidentally retracting. At the same time, this boltless connection method allows for quick decoupling, so that the cylinder unit can be disassembled and maintained independently without affecting the main structure of the robotic arm. This greatly shortens the equipment maintenance downtime and significantly improves the overall utilization rate of the production line.

[0036] The implementation principle of this embodiment is as follows: A turntable 3 is installed below the base 1 of the robotic arm, and a movable plate 4 is installed below the turntable 3. When it is necessary to change the position of the robotic arm, the second motor 804 is started. The second motor 804 drives the hydraulic pump, which outputs pressurized oil. The oil is delivered to the cylinder 805 through the hydraulic control valve group, which drives the piston rod 806 to extend and retract. The connecting ring 807 in front of the piston rod 806 is fastened to the pull ring 7, which further drives the movable plate 4 to move on the slide rail 202. When it is necessary to change the installation angle of the robotic arm, the first motor 5 is driven to drive the gear 6 to rotate, which further drives the turntable 3 to rotate, thereby changing the installation angle of the robotic arm.
