[0002] In the automotive manufacturing industry, sound insulation cotton is an important sound insulation and heat insulation material. Its quality and performance directly affect the comfort and quality of automobiles. PU polyurethane foaming process is widely used because it can produce sound insulation cotton with good sound insulation effect and lightweight characteristics. However, the traditional automotive sound insulation cotton PU polyurethane foam shaping device has gradually revealed some shortcomings in the long-term use, making it difficult to meet the modern automotive industry's high-quality, high-efficiency and diversified needs for sound insulation cotton production.

[0003] Existing foam forming devices use a fixed frame structure to install foam molds. The fixed frame structure has poor versatility. The height of the forming plate in traditional devices is usually fixed or has a limited adjustment range, making it difficult to adapt to molds of different heights. When it is necessary to produce sound insulation cotton of different thicknesses, the entire device needs to be replaced or complex modifications need to be made, which increases equipment investment and production costs. Therefore, this application designs an adjustable automotive sound insulation cotton PU polyurethane foam forming device to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4The adjustable automotive sound insulation cotton PU foam forming device of this utility model includes a workbench 1, on which a mold 2 is placed. The mold 2 facilitates the production of automotive sound insulation cotton foam parts that meet design requirements. Limiting components are symmetrically arranged on both sides of the mold 2 to prevent displacement of the mold 2 during operation, thus affecting product quality. T-slots 9 are symmetrically opened on both sides of the workbench 1, allowing for flexible adjustment of the position of the support plate 3, enhancing the adjustability and adaptability of the device. The support plate 3 is slidably connected within the T-slots 9, facilitating flexible adjustment of the support. A fixing block 6 is provided on one side of the workbench 1. The fixing block 6 provides a stable support base for the subsequent installation and movement of the support column 8; the support column 8 is slidably sleeved inside the fixing block 6, which provides stable support and height adjustment function for the shaping plate 5, ensuring that the shaping plate 5 can perform shaping operation on the foam part at a suitable height and position; the top surface of the support column 8 is equipped with a hinge seat 7, which increases the flexibility of the rotation adjustment of the shaping plate 5, and can better fit the shape of the mold 2 and the surface of the foam part; the shaping plate 5 is hinged on the hinge seat 7, which allows for effective control of the thickness, flatness and shape accuracy of the foam part, improving the quality and performance of the automotive sound insulation cotton.

[0020] In this utility model, the limiting component includes a support base 13 fixedly connected to the workbench 1. A threaded post 12 is internally threaded onto the support base 13, and a limiting plate 11 is provided at one end of the threaded post 12. The threaded post 12 facilitates the adjustability of the limiting component, allowing it to adapt to various sizes of molds 2 and improving the versatility of the device. The top of the support plate 3 has multiple interfaces equidistantly spaced, and railings 4 are inserted into these interfaces to prevent the shaping plate 5 from lifting upwards during operation. The railings 4 ensure the stability and reliability of the shaping process. The fixed block 6 has a horizontally opening for a connection port, and the support column 8 has multiple internal interfaces equidistantly opened. The fixed block 6 is equipped with a pin for flexibly changing the height of the shaping plate 5. The pin is inserted into the connection port and the internal interface. The pin can be used to fix the position of the support column 8 in the fixed block 6, and the height of the shaping plate 5 can be adjusted conveniently and quickly. One end of the mold 2 is equipped with a feed pipe 10. The inner wall of the feed pipe 10 is provided with an internal thread groove. The feed pipe 10 can be used to facilitate a stable supply of raw materials and ensure that the mold 2 can obtain enough raw materials for foaming and molding.

[0021] Working Principle: When using this utility model, the operator first places a suitable mold 2 on the workbench 1. Based on the size of the mold 2, the position of the limiting plate 11 is adjusted by rotating the threaded post 12 in the limiting component. Since the threaded post 12 is internally threaded to the support base 13, when the threaded post 12 is rotated, the limiting plate 11 will move closer to or further away from the mold 2 until the limiting plate 11 is tightly fitted to both sides of the mold 2, thus stabilizing and limiting the mold 2 and preventing displacement during subsequent work. Then, based on the height of the mold 2 and the production requirements of automotive sound insulation PU polyurethane foam parts, the support post 8 slides up and down within the fixed block 6. After adjusting column 8 to a suitable height, insert the pin into the connection port on the fixing block 6 and the corresponding inner interface on the support column 8 to fix the support column 8 at that height. This determines the height of the shaping plate 5 connected to the support column 8 via the hinge seat 7. Then, slide the support plate 3 in the T-slots 9 on both sides of the worktable 1 and adjust it to a suitable position. Insert the railing 4 into the equidistant interfaces at the top of the support plate 3 to limit the upward movement of the shaping plate 5 when injecting raw materials. Finally, inject PU polyurethane raw materials into the mold 2 through the feed pipe 10, wait for the foaming to finish, and then reset the workpiece. This completes the shaping device for adjustable automotive sound insulation cotton PU polyurethane foam parts.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
