Description

Technical Field

[0001] This utility model relates to the field of mold dual-mold fixing technology, and in particular to a dual-mold fixing device for train interior processing molds. Background Technology

[0002] The dual-mold fixing device for train interior processing molds has important applications. It can precisely position the molds, ensuring accurate alignment of the cavities of the upper and lower or complementary molds when processing train interior parts, effectively avoiding deviations in product size and shape, and guaranteeing uniform thickness and accurate installation. At the same time, the fixing device can stabilize the mold state, resist interference from vibration and collision of processing equipment, prevent mold displacement, and ensure processing accuracy. It can also improve processing efficiency, facilitate mold replacement and maintenance, reduce processing interruptions, and promote continuous production.

[0003] When the double-mold fixing device for train interior processing molds is in operation, the fixing device is first installed on the workbench of the processing equipment and its base is firmly fixed with bolts. Then, the two molds are placed in the predetermined positions of the fixing device, and the cavities are aligned by positioning pins or positioning grooves. Then, the clamping mechanism is activated, and clamping methods such as hydraulic, pneumatic or mechanical screws are used. For example, hydraulic clamping uses a hydraulic cylinder to push the clamping block to press the mold, ensuring that it is stable and does not shift during processing. After processing is completed, the clamping mechanism is released, and the mold is disassembled by lifting or manual handling. This cycle is repeated to complete the train interior processing work.

[0004] Although the above-mentioned device enables the processing of train interior decoration, the mold is usually fixed by bolts, which makes it difficult to change the mold during the production process and reduces work efficiency. Therefore, a dual-mold fixing device for processing train interior decoration molds is proposed to solve the above problems. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a dual-mold fixing device for train interior processing molds, including a housing 1. A lower mold 3 is placed inside the housing 1. A fixing component is installed inside the housing 1 for quickly fixing different types of molds and facilitating mold replacement. A fixing plate 12 is fixedly connected inside the housing 1, and a lifting component is installed at the bottom of the fixing plate 12 to drive the mold to close and release, achieving highly automated production. The fixing component includes a threaded rod 9, which is threadedly connected inside the housing 1. A fixing block 18 is fixedly connected to one end of the threaded rod 9. By rotating the threaded rod 9, the fixing block 18 can be moved, thereby pressing and fixing the lower mold 3.

[0032] Reference Figure 1 and Figure 3 The lifting assembly includes a cylinder 11, which is fixedly connected to the bottom of a fixed plate 12. A connecting column 17 is fixedly connected to the output end of the cylinder 11. The operation of the cylinder 11 causes the connecting column 17 to move up and down. Connecting rod 15 and connecting rod 16 are rotatably connected to the outer circumference of the connecting column 17. One end of connecting rod 15 and connecting rod 16 is slidably connected to a moving plate 13, and the other end of connecting rod 15 and connecting rod 16 is slidably connected inside the fixed plate 12. When the connecting column 17 moves up and down... When moving, it will cause connecting rod 15 and connecting rod 2 to slide inside the moving plate 13 and the fixed plate 12, thereby causing the moving plate 13 to move up and down. The moving plate 13 is fixedly connected to the inside of the fixed frame 14, and the fixed frame 14 is fixedly connected to the side of the magnetic block 4. When the moving plate 13 moves up and down, the fixed frame 14 will drive the magnetic block 4 to move up and down accordingly. The bottom of the magnetic block 4 is magnetically connected to the upper mold 2, thereby realizing the automatic mold closing and demolding of the upper mold 2 and the lower mold 3.

[0033] Reference Figures 1-3 The bottom of the upper mold 2 is fixedly connected with a positioning pin 7, and the lower mold 3 has a pin hole 8 inside. The positioning pin 7 and the pin hole 8 facilitate the positioning of the upper mold 2 and the lower mold 3, improving the accuracy of mold closing. The side of the threaded rod 9 is fixedly connected with a handle 6. Multiple handles 6 are provided, and multiple handles 6 are located on the side of the threaded rod 9. The handles 6 facilitate the rotation of the threaded rod 9. The side of the fixing block 18 is fixedly connected with an anti-slip block 19. The anti-slip block 19 is made of rubber, which increases the friction force for squeezing and fixing the lower mold 3, and improves the fixing effect of the lower mold 3. The side of the housing 1 is fixedly connected with a spring 10. Multiple springs 10 are provided. When the threaded rod 9 malfunctions, it will be temporarily fixed under the tension of the spring 10's return, ensuring smooth operation. The top of the moving plate 13 is fixedly connected with a telescopic rod 5. One end of the telescopic rod 5 is fixedly connected to the bottom of the fixing plate 12. The telescopic rod 5 makes the moving plate 13 more stable when moving up and down.

[0034] Working principle: First, when it is necessary to fix the mold, the lower mold 3 is placed at the designated position at the bottom of the housing 1, and the threaded rod 9 is rotated to move the fixing block 18. This is adjusted according to the size of the lower mold 3, and the lower mold 3 is fixed by tightening the threaded rod 9 and moving the fixing block 18. The operation is convenient and the mold can be easily replaced. Second, when it is necessary to fix the upper mold 2 and the lower mold 3, the cylinder 11 is operated, and the connecting column 17 drives the connecting rod 15 and the connecting rod 16 to slide inside the fixing plate 12 and the moving plate 13. This allows the upper mold 2 and the lower mold 3 to fit and be fixed together through the fixing frame 14 and the magnetic block 4, improving work efficiency and reducing the labor intensity of the workers.

[0035] 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.
