Description

Technical Field

[0001] The utility model relates to the technical field of railway rubber pad production equipment, in particular to a railway rubber pad mould. Background Art

[0002] Railway rubber pads are important components in the track structure. They are installed between the steel rails and concrete sleepers. Their main function is to buffer the high-speed vibration and impact generated when vehicles pass through the tracks and to protect the roadbed and sleepers. As the main vibration-absorbing component of high-speed trains, the quality of their performance has an important impact on the smoothness of the train's ride.

[0003] Traditionally, the production of rubber pads uses a hydraulic press to combine the upper and lower molds of the mold. This method is time-consuming and has low production efficiency, making it difficult to meet the requirements of rapid production. The existing lower mold cooling method is air cooling or water cooling, which makes it difficult to quickly demold the molded rubber pads, and even makes demolding difficult.

[0004] Therefore, it is very meaningful to design and process a set of special railway rubber pad molds with simple structure, quick demoulding and low mold opening cost. Summary of the invention

[0005] Based on the above background, the utility model proposes a new type of railway rubber pad mold, which solves the problems that the existing hydraulic press drives the upper and lower molds to combine and separate, consumes a lot of energy, and has low production efficiency; and the existing railway rubber pad mold cannot be cooled quickly and is difficult to demould. To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A railway rubber pad mold comprises a control switch, a motor, a rotating rod, a slide rail, an arc groove, a screw, an impeller, an upper mold, a lifting plate, a column, a liquid flow channel, a lower mold, an injection port, a frame, and a shell, wherein: the control switch is connected to the motor through a wire, the control switch is used to connect or disconnect the current of the motor, the motor is connected to the frame, the rotating rod is fixed to the motor, the slide rail is fixed to the upper mold through screws, the arc groove is fixed to the slide rail, lifting plates are arranged at both ends of the upper mold, the lifting plates are movably connected to the column, a lower mold is arranged below the upper mold, a frame is installed at one end of the column, and a shell is installed at the other end, a lower mold is installed on the shell, a liquid flow channel is arranged in the lower mold, and an injection port is arranged in the upper mold.

[0007] Preferably, a radiator is installed at the bottom of the lower mold, and there are cooling strips inside the radiator. There are gaps above adjacent cooling strips. An impeller is provided below the radiator and installed in the outer shell. When the impeller is started, the pressure around the impeller decreases, and the surrounding water flows upward along the cooling strips to the bottom of the lower mold, and moves downward through the gaps between adjacent cooling strips to cool the lower mold.

[0008] Preferably, after the injection molding is completed, the coolant flows into the lower mold through the liquid flow channel, and takes away the heat of the lower mold through the transverse liquid flow channel A and the longitudinal liquid flow channel B, so that the rubber pad and the lower mold are quickly demolded.

[0009] Compared with the background technology, this patent has the following beneficial effects:

[0010] 1. When the control switch is connected to the power supply, the motor drives the rotating rod to rotate within the arc groove, and the end of the rotating rod moves up and down in the slide rail; the slide rail and the upper mold are connected by screws, and when the end of the rotating rod moves up and down in the slide rail, it drives the upper mold and the lower mold to be combined and separated. This driving method requires a small torque and responds quickly, overcoming the shortcomings of traditional hydraulic presses such as high energy consumption and low working efficiency.

[0011] 2. This patent uses two cooling systems to cool the lower mold. The first cooling system injects coolant into the lower mold through the liquid flow channel, and cools the lower mold through the horizontal liquid flow channel A and the longitudinal liquid flow channel B; the second cooling system starts the impeller, the pressure around the impeller decreases, and the surrounding water flows upward along the heat dissipation strips to the bottom of the lower mold, and moves downward through the gaps between adjacent heat dissipation strips to cool the lower mold. These two cooling systems can quickly cool the formed rubber pad, quickly demold it, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
