The molding device can be various types of molds and mechanical equipment, which can heat, pressurize and cool the rubber material according to the design requirements to make it into the required shape and size, while eliminating internal stress to ensure the stability and reliability of the pad during use.
[0003] Traditional rail rubber pad molding devices usually include molds, heating and cooling systems, and pressure equipment. When in use, the rubber raw material is first placed in the mold, and then pressure is applied by the pressure equipment to evenly distribute the rubber in the mold to form the desired pad shape.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a rail under-rail rubber pad forming device, including a mixing chamber 1, a top cover 2 is fixedly connected to the top of the mixing chamber 1, a motor 3 is fixedly connected to the top of the top cover 2, a rotating plate 4 is fixedly connected to the output end of the motor 3, a rotating rod 5 is rotatably connected to the inside of the rotating plate 4, a gear 6 is fixedly connected to the top of the rotating rod 5, an annular rack 7 is fixedly connected to the inside of the top cover 2, the annular rack 7 is meshed with the gear 6, a rotating shaft 8 is fixedly connected to the outer wall of the rotating rod 5, a stirring blade 9 is rotatably connected to the outer wall of the rotating shaft 8, a guide plate 10 is fixedly connected to the inside of the mixing chamber 1, the bottom of the rotating rod 5 is slidably connected to the inner wall of the guide plate 10, a feeding assembly is arranged on the top of the top cover 2, and the feeding assembly includes an inlet plate 13 and a discharge plate 11, one end of the inlet plate 13 is fixedly connected to the inside of the top cover 2, and the outer wall of the discharge plate 11 is fixedly connected to the bottom of the mixing chamber 1;
[0024] Specifically, first, after the required raw materials are poured into the interior of the mixing bin 1 through the feeding plate 13, to ensure that the raw materials can be fully stirred and mixed, the motor 3 is started, and the output end of the motor 3 will drive the rotating plate 4 to rotate inside the top cover 2. At the same time, the rotation of the rotating plate 4 will drive the rotating rod 5 to rotate together, ensuring that the rotating rod 5 can rotate smoothly and accurately. A guide plate 10 is provided at the bottom to provide necessary support and guidance for it. As the rotating rod 5 rotates, the driven gear 6 will rotate along the annular rack 7, so that the gear 6 not only revolves around the annular rack 7, but also rotates at the same time. The linkage relationship between the gear 6 and the rotating rod 5 makes the rotating rod 5 rotate when the gear 6 revolves and rotates. Finally, when the rotating rod 5 rotates, it will drive the rotating shaft 8 to rotate together. The rotation of the rotating shaft 8 further activates the stirring blade 9, so that it can fully stir the raw materials in the mixing bin 1, ensuring that the raw materials can be evenly mixed in the mixing bin 1, thereby improving the quality of the product and the production efficiency.
[0025] Reference Figure 1 and Figure 3 The lower surface of the blanking plate 11 is fixedly connected with a conveying pipe 14, the bottom of the mixing bin 1 is fixedly connected with a fixed plate 12, the interior of the fixed plate 12 is fixedly connected with a motor 2 16, the output end of the motor 2 16 is fixedly connected with an auger blade 15, the outer wall of the auger blade 15 is rotatably connected to the inner wall of the conveying pipe 14, the conveying pipe 14 is fixedly connected to the interior of the fixed plate 12, the upper surface of the fixed plate 12 is fixedly connected with a motor 3 17, the output end of the motor 3 17 is fixedly connected with a bidirectional screw 18, both ends of the bidirectional screw 18 are rotatably connected to the interior of the fixed plate 12, the outer wall of the bidirectional screw 18 is fixedly connected with a transmission belt 19, the transmission belt 19 is arranged inside the fixed plate 12, the outer wall of the bidirectional screw 18 is threadedly connected with a mold 20, and the outer wall of the fixed plate 12 is provided with a double door 21;
[0026] Specifically, the raw material is accurately fed into the interior of the conveying pipe 14 through the blanking plate 11. At this time, the motor 2 16 starts working, and its output end drives the auger blade 15 to rotate, ensuring that the raw material can move forward evenly and stably inside the conveying pipe 14. After being conveyed for a certain distance, the raw material is accurately conveyed to the interior of the mold 20. Then the motor 3 17 is started, and its output end drives the bidirectional screw 18 to start rotating. At the same time, through the ingenious design of the transmission belt 19, the bidirectional screw 18 on the other side will also rotate synchronously, so that the upper and lower molds 20 begin to move relative to each other, pressing the raw materials inside, which not only ensures the tight molding of the raw materials, but also greatly improves the product quality and production efficiency.
[0027] Working principle: When the under-rail rubber pad forming device is needed, first pour the required raw materials into the mixing bin 1 through the feed plate 13, then start the motor 3, so that its output end drives the rotating plate 4 to rotate inside the top cover 2, and further drives the rotating rod 5 to rotate together, ensuring that the rotating rod 5 can rotate smoothly and accurately, and the guide plate 10 provides support and guidance for its bottom. As the rotating rod 5 rotates, the gear 6 is driven to rotate along the annular rack 7, so that the gear 6 not only revolves around the annular rack 7, but also rotates at the same time. Then, through the linkage between the gear 6 and the rotating rod 5, the rotating rod 5 can also rotate at its own speed. Finally, when the rotating rod 5 rotates at its own speed, it will drive the rotating shaft 8 to rotate together, and the stirring blade 9 can be activated to fully stir the raw materials in the mixing bin 1 to ensure that the raw materials can be evenly mixed.
[0028] At this time, the raw material is delivered to the inside of the conveying pipe 14 through the blanking plate 11, and then the auger blade 15 is driven to rotate through the output end of the motor 2 16, thereby driving the raw material to be evenly conveyed, and then transported to the inside of the mold 20, and then the bidirectional screw 18 is driven to rotate through the output end of the motor 3 17. At this time, the bidirectional screw 18 on the other side is driven to rotate synchronously through the transmission belt 19, thereby driving the upper and lower molds 20 to move relative to each other, and then performing compression molding.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
