Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding, and in particular to a material feeding mechanism for injection molded products. Background Technology
[0002] Injection molded products refer to a type of plastic product manufactured through injection molding. Injection molding is a very common and important method in plastic processing, widely used in various industries such as automobiles, home appliances, electronic products, packaging, medical devices, and toys. Due to its high efficiency and flexibility, injection molded products play an extremely important role in modern manufacturing. During the production of injection molded products, after the ejection system of the injection molding machine ejects the molded product, the product cannot automatically detach from the machine. At this time, the material handling mechanism of the injection molding machine needs to remove the product.
[0003] The existing publication number CN211640852U provides a material handling mechanism for injection molding machines that can guarantee positional accuracy. It uses a clamping rod to drive the clamping block to rotate inward to clamp and remove the injection molded product, thereby realizing the material handling of the injection molded product.
[0004] The existing patent has a fixed clamping block position, which can only clamp the left and right sides of the injection molded product. If the injection molded part is narrow in the front-to-back direction but wide in the left-to-right direction, it can easily affect the stability of clamping the injection molded product. In addition, some injection molded products have variable diameter structures, which can easily result in a small area of the injection molded product being subjected to clamping force. This can easily affect the stability of the injection molded product during the clamping and picking process, and make it difficult to accurately control the clamping force on the injection molded product. If the clamping force on the injection molded product is too large, it can easily damage the injection molded product. If the clamping force is too small, it can easily cause the injection molded product to fall, reducing the practicality of the picking mechanism. Summary of the Invention
[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a material feeding mechanism for injection molded products to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material handling mechanism for injection molded products, including a support frame, an adjusting frame disposed in front of the support frame, and a controller fixedly mounted on the side surface of the support frame. The adjusting frame is connected to the support frame through a connecting component disposed at the rear end, and the adjusting frame is provided with a clamping component for clamping injection molded products. The controller has a built-in microprocessor. The clamping component includes a second motor fixedly mounted on the adjusting frame and a connecting frame disposed at the bottom of the adjusting frame and connected to the bottom output shaft of the second motor.
[0007] Two sliding plates are slidably installed inside the connecting frame;
[0008] The skateboard is equipped with several miniature electric push rods, and each miniature electric push rod has a clamp on its piston rod.
[0009] The clamping plate includes a fixed plate connected to the piston rod of the micro electric push rod, a groove opened on the inner side of the fixed plate, a clamping plate movably installed in the groove, and a pressure sensor installed in the groove, with the sensing surface of the pressure sensor connected to the clamping plate.
[0010] The second motor and the pressure sensor are both electrically connected to the controller.
[0011] Preferably, the connecting assembly includes a first motor installed on the right end of the front face of the support frame, a movable frame slidably installed on the front end of the support frame, and a cylinder fixed on the movable frame. A screw is installed on the output shaft of the first motor. The front end of the movable frame is slidably connected to the adjusting frame. The bottom piston rod of the cylinder is connected to the adjusting frame. The screw is rotatably connected to the top of the inner side of the support frame and threadedly connected to the rear end of the movable frame. The first motor is electrically connected to the controller.
[0012] Preferably, the two sets of sliding plates, miniature electric push rods, and clamps within the connecting frame are symmetrical to each other.
[0013] Preferably, a third motor is fixedly mounted on the side surface of the connecting frame, and a bidirectional lead screw that is rotatably connected to the inner side of the connecting frame is fixedly mounted on the output shaft of the third motor. The bidirectional lead screw is threadedly connected to the upper end of the slide plate, and the third motor is electrically connected to the controller.
[0014] Preferably, a rubber sheet is attached to the end of the clamping plate away from the pressure sensor, and the clamping plate is flush with the side surface of the rubber sheet.
[0015] Preferably, a pressure sensor is installed at each of the upper and lower ends of the inner side of the groove, and the two pressure sensors are respectively connected to the upper and lower ends of the outer side of the clamping plate.
[0016] The beneficial effects of this utility model are:
[0017] This invention incorporates a clamping assembly. A second motor drives the connecting frame and clamping plates to rotate, adjusting the angle of the two sets of clamping plates. This allows the clamping plates to hold the larger side of the injection-molded product, improving the stability of the clamping process. Furthermore, multiple miniature electric push rods, working in conjunction with multiple clamping plates, allow for clamping at different outer diameter positions of the injection-molded product, increasing the area of the product subjected to clamping force and further enhancing stability during the material handling process. A pressure sensor detects the clamping force applied by the clamping plates, enabling more precise control of the clamping force, reducing damage to the injection-molded product, preventing it from falling off, and improving the practicality of the material handling mechanism.

Detailed Implementation
[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0023] like Figure 1 As shown, this utility model provides a material handling mechanism for injection molded products, including a support frame 1, an adjustment frame 2 disposed in front of the support frame 1, and a controller 7 locked and fixed to the side surface of the support frame 1. The adjustment frame 2 is connected to the U-shaped support frame 1 through a connecting component disposed at the rear end, and the adjustment frame 2 is provided with a clamping component for clamping the injection molded product. The controller 7 has a built-in microprocessor 8.
[0024] In this embodiment, the connecting components include a first motor 3 locked and fixed to the right end of the front end of the support frame 1, a movable frame 4 slidably mounted on the front end of the support frame 1, the movable frame 4 being able to move left and right along the upper end of the support frame 1, a cylinder 5 fixedly mounted on the movable frame 4, a screw 6 coaxially mounted on the output shaft of the first motor 3, the front end of the movable frame 4 being slidably connected to the adjusting frame 2, and the adjusting frame 2 being able to move up and down along the front end of the movable frame 4.
[0025] The bottom piston rod of cylinder 5 is connected to the adjusting frame 2, which facilitates the adjustment frame 2 to move up and down along the moving frame 4 by cylinder 5. The screw 6 is rotatably connected to the top of the inner side of the support frame 1, and the screw 6 is threadedly connected to the rear end of the moving frame 4, which facilitates the moving frame 4 to move horizontally along the support frame 1 when the screw 6 rotates. The first motor 3 is electrically connected to the controller 7.
[0026] Specifically, in use, the support frame 1 is fixed to the outside of the injection mold. After the injection product is produced, the first motor 3 is started to drive the screw 6 to rotate. The screw 6 drives the moving frame 4 to move horizontally, so that the moving frame 4 drives the clamping assembly to move above the injection product.
[0027] like Figures 1 to 3As shown, in this embodiment, the clamping assembly includes a second motor 9 that is locked and fixed on the adjusting frame 2, and a connecting frame 10 that is disposed at the bottom of the adjusting frame 2 and connected to the bottom output shaft of the second motor 9;
[0028] Two sliding plates 11 are slidably installed inside the connecting frame 10, and the sliding plates 11 can move horizontally along the inner side of the connecting frame 10.
[0029] Several miniature electric push rods 14 are installed on the slide plate 11. Each miniature electric push rod 14 has a clamping plate 15 on its piston rod. The miniature electric push rod 14 and the clamping plate 15 are used to clamp and pick up the injection molded product.
[0030] The clamping plate 15 includes a fixed plate 15a connected to the piston rod of the micro electric push rod 14, a groove 15b formed inside the fixed plate 15a, a clamping plate 15c movably installed in the groove 15b, and a pressure sensor 15e installed in the groove 15b. The sensing surface of the pressure sensor 15e is connected to the clamping plate 15c and is used to detect the clamping force applied by the clamping plate 15c to the injection molded product through the pressure sensor 15e.
[0031] The second motor 9 and the pressure sensor 15e are both electrically connected to the controller 7.
[0032] Among them, the two sets of sliding plates 11, micro electric push rods 14 and clamping plates 15 in the connecting frame 10 are symmetrical to each other, which facilitates the stable application of clamping force to the injection molding process.
[0033] Among them, a pressure sensor 15e is installed at each of the upper and lower ends of the inner side of the groove 15b. The two pressure sensors 15e are respectively connected to the upper and lower ends of the outer side of the clamping plate 15c, which improves the accuracy of detecting the clamping force applied by the clamping plate 15c to the injection molded product.
[0034] In this embodiment, a third motor 12 is fixedly mounted on the side surface of the connecting frame 10. A bidirectional lead screw 13 that is rotatably connected to the inner side of the connecting frame 10 is fixedly mounted on the output shaft of the third motor 12. The bidirectional lead screw 13 is threadedly connected to the upper end of the slide plate 11. The third motor 12 is electrically connected to the controller 7, so that the slide plate 11 can be driven to move horizontally by the third motor 12 in conjunction with the bidirectional lead screw 13.
[0035] In this embodiment, a rubber sheet 15d is attached to the end of the clamping plate 15c away from the pressure sensor 15e, and the side surface of the clamping plate 15c is flush with the side surface of the rubber sheet 15d to prevent the clamping plate 15c from causing wear to the outer surface of the injection molded product.
[0036] Specifically, in use, the second motor 9 is activated based on the shape of the product. The second motor 9 drives the connecting frame 10, the sliding plate 11, and the clamping plate 15 to rotate, causing the clamping plate 15 to rotate to face the wider side of the injection-molded product. Then, the cylinder 5 is activated to move the adjusting frame 2, the connecting frame 10, the sliding plate 11, and the clamping plate 15 downwards, causing the two clamping plates 15 to move to both sides of the injection-molded product. At the same time, the third motor 12 is activated to drive the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 drives the two sliding plates 11 to move inwards. The two sliding plates 11 respectively drive the two sets of micro electric push rods 14 and the clamping plate 15 to move inwards. When the clamping plate 15 moves to face the injection-molded product... When the products have a certain spacing, the spacing needs to be less than the extension distance of the piston rod of the micro electric push rod 14. Then, the micro electric push rod 14 drives the fixing plate 15a, clamping plate 15c and rubber sheet 15d to move inward to clamp the injection molded product. The clamping force applied by the clamping plate 15c to the injection molded product is detected by the pressure sensor 15e and the signal is transmitted to the controller 7. The signal is processed by the microprocessor 8. When the applied clamping force reaches the preset value, the micro electric push rod 14 stops working. At this time, the cylinder 5 is controlled again to drive the clamping plate 15c and the injection molded product to move upward to disengage from the mold, so as to complete the material removal of the injection molded product.
