[0001] The utility model relates to the technical field of injection molding production equipment, in particular to a fixture for removing automobile injection molding parts. Background Art
[0002] With the development of economy, cars have entered people's daily life. The decoration parts inside cars are mainly made of interior plastic parts, and many interior plastic parts of cars are often injection molded by injection molding equipment. After the injection molding equipment completes the injection molding of plastic parts, it is usually manually removed, which is inconvenient, low in automation, time-consuming and labor-intensive, and reduces work efficiency.
[0003] Although some equipment uses a picking fixture instead of manual picking, in the actual production process, the picking fixture is generally used in conjunction with a robotic arm to perform material unloading operations, which requires high operating accuracy. In addition, during long-term operation, it is inevitable that the distance between the picking fixture and the plastic parts will increase or decrease due to the shaking of the robotic arm or the vibration of the equipment, which will lead to material unloading failure and shutdown.

Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

[0023] Combination Figure 1-4 As shown, a fixture for removing automobile injection molded parts includes:
[0024] The fixed frame 1 is a rectangular metal frame used to support and fix the pickup structure;
[0025] The clamping assembly 2 is arranged at the four corners of the fixing frame 1 and is fixed and installed in sequence by bolts. The top surface thereof is provided with a clamping claw 23 and a suction cup 24, and is double fixed by clamping and adsorption;
[0026] The U-shaped frame 3 is arranged on the periphery of the fixed frame 1 and is movably connected to the fixed frame 1. The top of the U-shaped frame 3 is connected to the mechanical arm to facilitate the clamping and lifting of the fixed frame 1.
[0027] Specifically, mounting holes are respectively provided at the four corners of the fixed frame 1, and a group of clamping components 2 are provided at each mounting hole, and the clamping components 2 and the fixed frame 1 are in a vertical state.
[0028] In addition, the U-shaped frame 3 is rotatably connected to the fixed frame 1 using a connecting shaft 31. In order to facilitate the cooperation with the clamping component 2 on the fixed frame 1, the fixed frame 1 should be designed to be flipped up and down so that it can be in a horizontal or vertical state. Therefore, a servo motor is set on one side of the U-shaped frame 3, and the output shaft of the servo motor is transmission-connected to the connecting shaft 31, and the transmission shaft should be fixedly connected to the fixed frame 1.
[0029] The clamping assembly 2 includes a shell 21, the top of which is provided with a clamping claw 23 and a suction cup 24, and the top surface of the shell 21 is also provided with a corresponding slide groove 22, two clamping claws 23 are arranged and arranged in sequence inside the slide groove 22, and the suction cup 24 is arranged at the center of the two groups of clamping claws 23.
[0030] Both slide grooves 22 extend toward the inside of the housing 21 and are connected. At the same time, matching groove assembly structures are provided on the inner wall of the slide groove 22 and the side wall of the vertical section of the claw 23, so that the claw 23 can move horizontally in the slide groove 22 and maintain a vertical state.
[0031] An adjusting disk 25 is also provided inside the shell 21. The adjusting disk 25 is fixedly connected to the inner wall of the shell 21 by means of surrounding brackets, and the adjusting disk 25 located at the center is connected to the bracket by means of a bearing structure, so that it can rotate flexibly. At the same time, the center of the adjusting disk 25 is partially hollowed out to make it annular, and a limiting groove is provided on the upward side. The structure is a spiral groove arranged in a gradually opening manner, and the bottom end of the claw 23 is vertically inserted into the limiting groove. Therefore, when the adjusting disk 25 rotates, the arc-shaped spiral groove can be used to drive the two claws 23 to move relative to or back to each other, thereby achieving a clamping or unfolding effect.
[0032] The top surface of the suction cup 24 should also be provided with an elastic pad, which can be a silicone pad or other high-temperature resistant elastic material. At the same time, a pressure sensor is set at the place where the suction cup 24 is connected to the center of the top surface of the shell 21. The pressure sensor can be any one of the models such as G1 / 4A (BSP), 1 / 4NPT, SAE7 / 16-20UNF, etc.
[0033] A driving gear 26 is also provided on the bottom surface of the adjusting disk 25, and a driving motor 27 is arranged at intervals below the adjusting disk 25. The bottom of the driving motor 27 is fixedly connected to the inner bottom surface of the shell 21, and the output end is arranged vertically upward and provided with a gear sleeve at the end, which meshes with the driving gear 26.
[0034] A connecting sleeve 28 is also slidably mounted on the outer wall at the bottom of the shell 21. The bottom end of the connecting sleeve 28 is provided with a flange and is fixedly connected to the fixing frame 1 by bolts. At the same time, a limiting ring is provided at the top thereof. Therefore, the shell 21 can only be extended and retracted inside the connecting sleeve 28 and cannot be pulled out, and the longest extension distance is half the length of the shell 21.
[0035] Four groups of electric telescopic rods 4 are also provided on the back of the fixed frame 1. The four groups of electric telescopic rods correspond to the four groups of clamping components 2 respectively. The electric telescopic rods 4 are fixed to the back of the clamping component 2 by bolts, and the top of the telescopic end is extended to the inside of the connecting sleeve 28 and fixedly connected to the center of the top surface of the shell 21. Therefore, in actual use, the structure can cooperate with the above-mentioned pressure sensor to ensure that the pressure is always consistent. Therefore, even when the equipment is affected by external factors and causes errors between the picking tooling and the plastic parts, the structure can be quickly adjusted to avoid failures and shutdowns during unloading, thereby ensuring the stable operation of the equipment.
[0036] In order to facilitate the automatic operation of the driving motor 27, the pressure sensor, the electric telescopic rod 4 and the driving motor 27 should be electrically connected by wires inside the housing 21, and a PLC microcontroller should be installed between the three so that the clamping assembly 2 can be automatically driven after detecting a certain squeezing force.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
