Description

Technical Field

[0001] This utility model relates to a continuous forming mold for synthetic brake shoe backing, particularly the LH2 type continuous forming mold for synthetic brake shoe backing used in railway vehicles. Background Technology

[0002] like Figure 1 , Figure 2 As shown, the back 17 of the LH2 synthetic brake shoe for railway vehicles is flat before molding. Because it has irregular support plates 21 and folding plates 22 at both ends, it is difficult to continuously feed the product to be processed and automatically discharge the material after molding. Currently, manual feeding and discharge are used, which makes continuous molding processing impossible and affects production efficiency. Summary of the Invention

[0003] The purpose of this utility model is to address the aforementioned shortcomings of the existing technology by providing a continuous forming mold for synthetic brake shoe backing. This mold enables continuous feeding of products to be processed and automatic material discharge after forming, allowing for continuous forming processing, thereby improving production efficiency. It also offers high positioning accuracy and ensures product quality.

[0004] To achieve the above objectives, this utility model provides a continuous forming mold for the back of a synthetic brake shoe, comprising an upper mold and a lower mold. The upper mold includes a connected upper template and a back forming upper mold, a nose forming upper mold fixed to the middle of the back forming upper mold, and a positioning pin fixed to the center of the nose forming upper mold. The lower mold includes a connected lower template and a back forming lower mold, and a nose forming lower mold fixed to the back forming lower mold. The characteristic feature is that slider seats are fixedly connected to the lower templates on both sides of the back forming lower mold. Two or more compression springs are provided in the longitudinal grooves of the slider seats, and guide sliders are placed on the compression springs. Guide angle steels are fixedly connected to the upper ends of the guide sliders. The two guide angle steels are symmetrically arranged around the center line of the positioning pin, and the horizontal plates of the two guide angle steels are arranged opposite each other. Triangular positioning blocks are fixedly connected to the rear ends of the guide angle steels.

[0005] In this invention, during the forming process, the two ends of the product to be processed are placed on two guide angle steels and pushed to the triangular positioning blocks for positioning, reaching the forming station. At this time, the press slide moves the upper template downward. While the upper and lower molds are forming the product to be processed, the guide angle steels are pressed down simultaneously. After forming, the press slide moves upward, and the guide angle steels return to their original positions under the action of the compression spring. Because the formed product is arc-shaped and has a nose-like structure in the middle, its length is reduced, allowing it to pass between the two triangular positioning blocks. When the next product to be processed is pushed to the forming station, the formed product is pushed out and automatically discharged. This invention can realize continuous feeding of products to be processed and automatic discharge after forming. During the cycle, the press can be in a continuous stroke working state, enabling continuous forming processing, thereby improving production efficiency. Furthermore, the two guide angle steels are symmetrically arranged around the center line of the positioning pins, ensuring high workpiece positioning accuracy and guaranteeing product quality. As a further improvement of this utility model, two support seats are fixedly provided on the lower template at the rear side of the two slider seats, and a receiving plate is fixedly connected to the two support seats. The receiving plate is at the same height as the horizontal plate of the two guide angle steels; the formed product is pushed onto the receiving plate for easy transfer. As a further improvement of this utility model, the lower section of the guide slider is provided with two or more blind holes, and the upper section of each compression spring is placed in its respective blind hole; this can prevent the guide slider from falling off the compression spring and facilitate accurate resetting. In summary, this utility model can realize the continuous feeding of products to be processed and the automatic discharge after forming, enabling continuous forming processing, thereby improving production efficiency, and with high positioning accuracy, it can ensure product quality.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings.

[0012] like Figures 3 to 4As shown, this embodiment of a synthetic brake shoe back continuous forming mold includes an upper mold and a lower mold. The upper mold includes an upper template 12 and a back forming upper mold 11 connected by bolts, a nose forming upper mold 10 fixed to the middle of the back forming upper mold, and a positioning pin 9 fixed to the center of the nose forming upper mold. The lower mold includes a lower template 1 and a back forming lower mold 3 connected by bolts, and a nose forming lower mold 8 fixed to the back forming lower mold. Slider seats 2 are fixed to the lower templates 1 on both sides of the back forming lower mold 3 by screws 15. Two compression rods are provided in the longitudinal groove of the slider seat 2. Spring 4, guide slider 5 placed on compression spring 4, the lower section of guide slider 5 is provided with two blind holes, the upper section of each compression spring 4 is placed in its respective blind hole, guide angle steel 6 is welded and fixed to the upper end of guide slider 5, the two guide angle steels 6 are symmetrically arranged with the center line of positioning pin 9, the horizontal plates of the two guide angle steels 6 are set opposite each other, and the rear end of each guide angle steel 6 is fixedly connected with a triangular positioning block 7; two support seats 13 are fixed on the lower template 1 on the rear side of the two slider seats 2, a receiving plate 16 is fixedly connected to the two support seats 13, and the receiving plate 16 is at the same height as the horizontal plate of the two guide angle steels 6.

[0013] In this invention, during the forming process, the two ends of two or more products 17 to be processed are placed on the horizontal plate of two guide angle steels 6 and pushed to the triangular positioning block 7 for positioning, reaching the forming station. At this time, the press slide moves the upper template 12 downward. When the upper and lower molds form the products 17 to be processed, the upper mold overcomes the resistance of the compression spring 4 and presses down the two guide angle steels 6. After forming, the press slide moves upward, and the guide angle steels 6 return to their original position under the action of the compression spring 4. Figure 5 As shown, since the formed product 18 is arc-shaped and has a tile nose 19 in the middle, its length is reduced, allowing it to pass between the two triangular positioning blocks 7. When the next product to be processed is pushed to the forming station, the formed product is pushed out and automatically discharged. This utility model can realize the continuous introduction of products to be processed and the automatic discharge after forming. During the cycle, the press can be in a continuous stroke working state, and continuous forming processing can be performed, thereby improving production efficiency. Moreover, the two guide angle steels 6 are symmetrically arranged with the center line of the positioning pin 9, and the workpiece positioning accuracy is high, which can ensure product quality. The formed product is pushed onto the receiving plate 16 for easy transfer. The upper part of each compression spring 4 is placed in its respective blind hole, which can prevent the guide slider 5 from falling off the compression spring 4 and facilitate accurate reset.
