Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to a rotary clamping fixture for removing the casting gate of an automotive interior panel. Background Technology

[0002] As the automotive manufacturing industry moves towards higher quality and intelligence, the processing precision and appearance quality of automotive interior panels have become important indicators for measuring vehicle grade. Injection molding, as the mainstream production process for interior panels, directly affects the panel's fit, surface smoothness, and visual appeal if the residual gates are not properly removed. With consumers' increasing demands for the quality of automotive interior details and the strict control of production line efficiency, developing automated equipment capable of efficiently and accurately removing gates has become a key R&D direction for the automotive parts manufacturing industry to optimize production processes and reduce cost losses.

[0003] In existing technologies, automotive interior panel casting gate removal equipment often employs a combination structure of a fixed tooling platform, a manually adjustable clamp, and a thermal cutting tool. The technical principle involves manually inserting the interior panel into a tooling slot equipped with mechanical positioning pins. A side baffle is then used to roughly fix the panel using a manual knob or lever mechanism. The operator then uses a heated, clamp-like cutting tool, relying on experience to determine the casting gate location. The high temperature of the clamp softens the plastic at the casting gate, and external force is applied to cut and remove it. Some equipment is equipped with a simple foot switch to control the heating of the clamp, synchronizing with the operator's rhythm.

[0004] However, the existing technology that relies on manual operation of hot clamps to remove the casting gate has significant shortcomings. On the one hand, the manual completion of the entire process, including panel positioning, handheld hot clamp alignment, and force control, results in a long processing time for a single product and low overall production efficiency, making it difficult to meet the high-speed operation requirements of modern production lines. On the other hand, during the operation, it is difficult to accurately control the clamping force manually, and slight vibrations during hot clamp operation can easily scratch the product surface, affecting the appearance quality of the interior panel. Therefore, a rotary clamping fixture for removing the casting gate of automotive interior panels is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary clamping fixture for removing the casting gate of automotive interior panel, which aims to improve the problems of low efficiency of manual operation, poor stability caused by uneven clamping force or vibration due to human factors, and easy scratching of product surface during operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary clamping fixture for removing the casting gate of an automotive interior panel includes a base plate, a positioning plate fixedly connected to the top of the base plate, a plurality of vertical cylinders provided on the top of the base plate, a clamping plate I provided at the output end of each vertical cylinder, a rotating assembly provided on the outer wall of each clamping plate I, a plurality of corner pressing cylinders fixedly connected to the top of the base plate, and a clamping plate II fixedly connected to the output end of each corner pressing cylinder.

[0008] As a further description of the above technical solution:

[0009] Multiple clamping plates one and two are located on the top of the positioning plate, and each of the vertical cylinders and the corner pressing cylinders has an air inlet hole on its outer wall.

[0010] As a further description of the above technical solution:

[0011] The rotating assembly includes multiple rotating bars II, each of which is rotatably connected inside the clamping plate I.

[0012] As a further description of the above technical solution:

[0013] Each of the rotating bars has a support base fixedly connected to its outer wall, and each support base has a connecting base fixedly connected to its bottom.

[0014] As a further description of the above technical solution:

[0015] The outer walls of multiple connecting seats are fixedly connected to the surface of the groove at the top of the base plate, and a rotating bar is fixedly connected to the inner wall of each connecting seat.

[0016] As a further description of the above technical solution:

[0017] Each of the vertical cylinders is rotatably connected to the outer wall of the rotating bar three, and a connecting rod is fixedly connected to the output end of each of the vertical cylinders.

[0018] As a further description of the above technical solution:

[0019] Each of the connecting rods is rotatably connected to a rotating bar, and the outer wall of each rotating bar is fixedly connected to the inside of the clamping plate.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, a vertical cylinder and a corner-pressing cylinder are set up to drive clamping plates one and two to automatically rotate, press, and release the automotive interior panel. This replaces the traditional manual hot clamp removal process for injection molded parts, effectively solving the key problems of low efficiency of manual operation, poor stability caused by uneven clamping force or vibration due to human factors, and easy scratching of the product surface during operation. It enhances the stability and repeatability of the subsequent milling gate operation, thereby ensuring processing quality, improving overall production efficiency, and significantly reducing the amount of subsequent grinding work caused by uneven cuts.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3This utility model provides an embodiment of a rotary clamping fixture for removing the gate of an automotive interior panel. The fixture includes a base plate 1, with a positioning plate 2 fixedly connected to the top of the base plate 1. The positioning plate 2 precisely supports and positions the automotive interior panel from which the gate needs to be removed, providing a reference for subsequent clamping and processing. Multiple vertically positioned cylinders 4, serving as the main power source, are installed on the top of the base plate 1. A rotating assembly is installed on the outer wall of each clamping plate 6. This rotating assembly is the core mechanism for realizing the rotation function of the clamping plate 6, ensuring its smooth and accurate movement. Simultaneously, multiple corner brackets are also fixedly connected to the top of the base plate 1. The downward pressing cylinder 11, a corner pressing cylinder 11, is used to drive the clamping plate 12 to complete a combined action of rotation and pressing, in order to adapt to the clamping requirements of different positions of the product. Each corner pressing cylinder 11 has a clamping plate 12 fixedly connected to its output end. Multiple clamping plates 6 and 12 are located on top of the positioning plate 2 during operation. They work together to firmly press the workpiece onto the positioning plate 2 from different directions, preventing displacement during the milling of the gate, thus achieving a stable clamping effect. Each vertical cylinder 4 and corner pressing cylinder 11 has an air inlet on its outer wall. These air inlets are used to connect to an external air source for control. The extension and retraction of the cylinder, specifically the rotating assembly includes multiple rotating bars 9, each rotatably connected inside the clamping plate 6. Each rotating bar 9 serves as the central axis of rotation for the clamping plate 6, determining its rotation trajectory. A support seat 7 is fixedly connected to the outer wall of each rotating bar 9. This support seat 7, together with the connecting seat 3 below, forms a stable support structure for precisely fixing the rotation center in a predetermined position. A connecting seat 3 is fixedly connected to the bottom of each support seat 7. The outer walls of multiple connecting seats 3 are fixedly connected to the surface of the groove at the top of the base plate 1. This connection method ensures the rotation of the assembly... The installation is stable and the position is precise, which provides a foundation for the reliable operation of the clamping mechanism. Each connecting seat 3 has a rotating bar 10 fixedly connected to its inner wall, and each vertical cylinder 4 is rotatably connected to the outer wall of the rotating bar 10. Each vertical cylinder 4 has a connecting rod 5 fixedly connected to its output end. The connecting rod 5 is used to transmit the linear motion of the cylinder to the clamping plate 6. Each connecting rod 5 has a rotating bar 8 rotatably connected inside, and the outer wall of each rotating bar 8 is fixedly connected to the inside of the clamping plate 6. Through the cooperation of the connecting rod 5 and the rotating bar 8, the extension and retraction action of the vertical cylinder 4 can be effectively converted into the rotational clamping or loosening action of the clamping plate 6.

[0029] Working principle: During initial use, turn on the air circuit switch and gas reversing device connecting the vertical cylinder 4 and the corner pressing cylinder 11. The output end of the vertical cylinder 4 will retract inward, driving the clamping plate 6 to rotate with the rotating bar 9 on it as the rotation center through the connecting rod 5, until the pressing end of the clamping plate 6 is completely removed from the upper area of ​​the positioning plate 2. At the same time, the corner pressing cylinder 11 also moves synchronously, driving the clamping plate 12 to rotate and move upward, also leaving the top of the positioning plate 2, thus making room for placing the workpiece. Then, place the automotive interior panel that needs to have its gate removed on the positioning plate 2, ensuring accurate positioning. After positioning, reverse the air circuit, and the output end of the vertical cylinder 4 extends, again through the connecting rod 5. The clamping plate 6 is pushed to rotate in the opposite direction around the rotating bar 9, returning to the top of the positioning plate 2. At the same time, the clamping plate 12 is also driven by the corner pressing cylinder 11 to return to the clamping position. Together, they firmly press the workpiece onto the positioning plate 2 for subsequent milling of the gate. This automated rotary clamping method replaces the traditional manual hot clamping process for removing the gate of injection molded parts. It effectively solves the problems of low efficiency of manual operation, poor stability caused by uneven force or vibration, and easy scratching of the product surface during operation. It achieves stable clamping, enhances the stability and repeatability of the gate removal process, ensures processing quality, improves production efficiency, and reduces subsequent grinding work caused by uneven cuts.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
