Technical Field

[0001] This utility model belongs to the field of automatic material handling technology for injection molding machines, specifically an automatic material handling device for injection molding machines. Background Technology

[0002] An injection molding machine, also widely known as an injection molding machine or injection molding machine, is a key piece of plastic molding equipment that uses plastic molds to manufacture plastic products of various shapes and sizes. This machine plays a crucial role in the production process of plastic products. After the injection molding process is complete, the injection molding machine works in conjunction with an automatic unloading device to efficiently and accurately remove the molded plastic product from the mold, thereby ensuring a smooth and efficient production process.

[0003] Existing automated material handling equipment has the following problems: First, material handling is mainly completed by a robotic arm in conjunction with a gripper, which is not efficient and the teaching cost of the robotic arm is high. Second, the angle at which the gripper grasps the injection molded part is difficult to adjust, which further increases the cost of use. Utility Model Content

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1-3 As shown, this utility model provides a technical solution:

[0020] An automatic material handling device for an injection molding machine includes a frame 1, two guide rails 2 fixedly connected to the frame 1, two racks 3 fixedly connected to the frame 1, a movable frame 4 slidably connected to the guide rails 2, a rotating shaft 5 rotatably connected to the movable frame 4, gears 6 coaxially fixedly connected to both ends of the rotating shaft 5, the gears 6 meshing with the racks 3 on the corresponding side, a first pulley 7 coaxially fixedly connected to the rotating shaft 5, a motor 8 fixedly connected to the movable frame 4, a second pulley 9 coaxially fixedly connected to the output end of the motor 8, a belt 10 sleeved between the second pulley 9 and the first pulley 7, and a limit frame 11 fixedly connected to the bottom of the movable frame 4 for limiting movement. A gripper support frame 12 is slidably connected to the frame 11. A threaded rod 13 is rotatably connected to the movable frame 4. One end of the threaded rod 13 is fixedly connected to a first bevel gear 14. The threaded rod 13 is threadedly connected to a threaded hole on the gripper support frame 12. A second bevel gear 15 is coaxially fixedly connected to the output end of the motor 8. The second bevel gear 15 meshes with the first bevel gear 14. Two limit switches 16 are fixedly connected to both sides of the frame 1. The limit switches 16 are connected to the motor 8. A limit block 17 is provided on the limit frame 11. A gripper 18 is fixedly connected to the gripper support frame 12. The gripper 18 is connected to the limit switch 16. When the equipment is started... When motor 8 starts to rotate, the second pulley 9 on its output end drives the first pulley 7 to rotate via belt 10. The rotating shaft 5 also rotates, and the gear 6 fixed to it also rotates. Because gear 6 meshes with rack 3, the moving frame 4 slides along guide rail 2 under the meshing transmission of gear 6 and rack 3. Simultaneously, the second bevel gear 15 on the output end of motor 8 also rotates, and the meshing first bevel gear 14 also rotates. The threaded rod 13 also rotates with the rotation of the first bevel gear 14. Under the constraint of the limit frame 11, the gripper support frame 12, which cooperates with the threaded rod 13, moves vertically upward. The horizontal movement of the moving frame 4 and the vertical upward movement of the gripper support frame 12 cause the gripper 18 to move closer to point A, where the injection molded part is located. When the moving frame 4 moves to the edge position, it will trigger the limit switch 16. After the limit switch 16 is triggered, the gripper 18 will close, thereby realizing the gripping of the injection molded part. At the same time, the motor 8 reverses, the moving frame 4 begins to move in the opposite direction, and the gripper support frame 12 begins to descend until the moving frame 4 triggers the limit switch 16 on the other side. Then the motor 8 reverses again and the gripper 18 opens, placing the injection molded part at point B, which is lower. Repeating the above steps can realize the automatic material handling of the injection molding machine.

[0021] A protective shell 19 is fixedly connected to the frame 1. The protective shell 19 protects the equipment and ensures the safety of the operators.

[0022] The working principle of this utility model is as follows:

[0023] When the equipment is started, motor 8 begins to rotate. The second pulley 9 on its output end drives the first pulley 7 to rotate via belt 10. The rotating shaft 5 also rotates, and the gear 6 fixed to it also rotates. Because gear 6 meshes with rack 3, the moving frame 4 slides along guide rail 2 under the meshing transmission of gear 6 and rack 3. Simultaneously, the second bevel gear 15 on the output end of motor 8 rotates, and the meshing first bevel gear 14 also rotates. The threaded rod 13 also rotates with the rotation of the first bevel gear 14. Under the constraint of the limit frame 11, the gripper support frame 12, which cooperates with the threaded rod 13, moves vertically upwards. The horizontal movement of the moving frame 4 and the vertical upward movement of the gripper support frame 12 cause the gripper 18 to move closer to point A, where the injection molded part is located. When the moving frame 4 reaches the edge, it triggers the limit switch 16. After the limit switch 16 is triggered, the gripper 18 closes, thus gripping the injection molded part. At the same time, the motor 8 reverses, the moving frame 4 begins to move in the opposite direction, and the gripper support frame 12 begins to descend until the moving frame 4 triggers the limit switch 16 on the other side. Then, the motor 8 reverses again and the gripper 18 opens, placing the injection molded part at point B, which is lower. Repeating the above steps enables automatic material handling by the injection molding machine. The protective shell 19 protects the equipment and ensures the safety of the operator.

[0024] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
