Technical Field

[0001] This utility model relates to the field of automotive injection molding product processing technology, specifically to a high-efficiency injection clamping device. Background Technology

[0002] In modern automotive injection molding, various inserts are often required. These inserts are usually manually installed into the mold. Some inserts are small, and the operating space is limited, which cannot meet the needs of mass production. This also results in low assembly accuracy and quality. Using fixed fixtures requires frequent replacement, which is inflexible and increases production costs. Utility Model Content

Detailed Implementation

[0022] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0023] like Figures 1-4 As shown, this utility model discloses a high-efficiency injection molding gripper device, including a gripper mounting plate 1, which is connected to a movable module; the gripper mounting plate 1 is provided with a finished product gripper 2 for holding the injection molded product and a pin gripper 3 corresponding to the pin model required for injection molding. The finished product gripper 2 is designed according to the shape of the corresponding injection molded product and can directly use commonly used injection molding product jigs in the prior art to ensure that the injection molded product can be taken out of the mold; the pin gripper 3 is set on a quick-change tooling plate 4, which is detachably connected to the gripper mounting plate 1. The gripper mounting plate 1 is provided with an ejector mechanism for inserting the pin into the injection mold at the position of the pin held by the pin gripper 3.

[0024] This invention utilizes a detachable quick-change tooling plate 4 to flexibly replace the pin clamps, meeting the implantation needs of various injection molding pins or other components, improving the flexibility of the device. Furthermore, by setting different clamp types, multiple pins can be implanted simultaneously in batches, ensuring accuracy and uniformity, and improving injection molding efficiency. The clamp mounting plate 1 is equipped with positioning pins 11 that are positioned relative to the injection mold, ensuring the accuracy of the pin insertion position within the mold. A ball-head plunger 12 is provided on the side of the clamp mounting plate 1 closest to the injection mold, limiting the distance between the clamp mounting plate 1 and the injection mold, controlling the pin placement position to ensure the implantation depth meets requirements.

[0025] The pin clamp 3 used in this invention includes a motor pin clamp, a ground pin clamp, and a signal pin clamp. For larger pins, such as the clamps corresponding to the motor pin and ground pin of this invention, each includes a clamp cylinder 5 and a clamping block 6 disposed at the drive end of the clamp cylinder. The corresponding pin is clamped by the clamping block 6. For cases where the structure size is small and batch implantation is required, such as the signal pin clamp of this invention, it includes a clamping cylinder 7 and a sliding plate 13 disposed at the two drive ends of the clamping cylinder 7. The clamping cylinder 7 is fixedly mounted on the corresponding quick-change tooling plate 4. The surface of the sliding plate 13 is provided with several paddles 8 that pass through the quick-change tooling plate. The two sliding plates 13 are arranged in parallel and the paddles 8 face opposite directions. The quick-change tooling plate 4 has a sliding groove for the paddles 8 to slide along the opening and closing direction of the clamping cylinder. The paddles 8 on the two sliding plates 13 form a paddle group for clamping the signal pin. When the clamping cylinder 7 is activated, it drives the sliding plate 13 to move synchronously to clamp and release the signal pin.

[0026] like Figure 4 As shown, the ejector mechanism of this utility model includes a push cylinder 9 fixed on the corresponding quick-change tooling plate 4 and an ejector pin 10 fixed at the end of the push cylinder 9. After the ejector pin passes through the quick-change tooling plate, it corresponds to the position of the pin held by the pin clamp. For some parts that need to be implanted at a different depth than other pins, they can be implanted by pushing through the ejector mechanism to meet the specific requirements of the injection molded parts.

[0027] In use, after the pins are gripped, the moving module moves the gripper mounting plate and the pin grippers. The moving module uses a multi-axis manipulator or cylinder to move the gripper device forward into the injection molding machine. First, the finished product gripper 2 grabs the finished product onto the tray. Then, a new mold is placed on the injection molding machine. When the injection clamping device descends above the mold, the cylinders on the three types of pins will push out again. The ejector mechanism will more accurately insert the motor pins and ground pins into the mold. At the same time, the signal pins on the signal pin gripper can be directly inserted into the mold. After all the pins are inserted, the injection clamping device returns to the state when it was gripping the pins, waiting for the next pin gripping and insertion.
