1000 Ton PLC control Rubber Damping Plate Hydraulic Molding Press, Rubber Vulcanization Molding Machine

1. Hydraulic System Operation
   • The hydraulic molding press operates based on Pascal's law. A hydraulic pump pressurizes the hydraulic fluid (usually oil). The pressurized fluid is then directed through a system of valves and hoses to the hydraulic cylinders. When the hydraulic cylinders receive the pressurized fluid, they extend or retract, depending on the design of the press. In the case of a rubber damping plate press, the cylinders usually move the upper platen (movable part) towards the lower platen to apply pressure on the rubber material and the mold.
   • The pressure can be precisely controlled. For example, depending on the size and thickness of the damping plate, the pressure can range from a few tons to several dozen tons. The speed of the platen movement can also be adjusted through the hydraulic system to ensure a smooth and controlled molding process.
2. Molding Process
   • The rubber material, usually in a pre - cut or pre - formed shape, is placed in the mold cavity. The mold is designed to give the damping plate its specific shape and dimensions. When the upper platen moves down and applies pressure, the rubber is forced to fill the mold completely. At the same time, the heat from the platens (if the press has a heating function) and the pressure cause the rubber to take the shape of the mold and undergo a molding process.
   • If the press is a vulcanizing press (some damping plate presses have vulcanization capabilities), during the molding, a vulcanization reaction may also occur. In vulcanization, the rubber molecules cross - link with the help of vulcanizing agents (such as sulfur) under heat and pressure. This cross - linking process significantly improves the mechanical properties of the rubber, making it more durable and better able to withstand repeated compressive and shear forces.

1. Hydraulic System
   • Hydraulic Pump: It is the heart of the hydraulic system, responsible for drawing in and pressurizing the hydraulic fluid. There are different types of hydraulic pumps such as gear pumps, vane pumps, and piston pumps. The choice of pump depends on factors like the required pressure, flow rate, and the overall performance of the press.
   • Hydraulic Cylinders: These are the actuators that convert the hydraulic energy into mechanical force. They are usually made of high - strength steel and have a piston and a cylinder body. The number and size of the cylinders depend on the size and capacity of the press. For a large - sized rubber damping plate press, multiple cylinders may be used to ensure even pressure distribution.
   • Hydraulic Valves: They control the flow direction, pressure, and flow rate of the hydraulic fluid. There are different types of valves such as directional valves, pressure - control valves, and flow - control valves. The directional valves determine the direction of the hydraulic cylinder's movement, the pressure - control valves maintain the desired pressure, and the flow - control valves adjust the speed of the platen movement.
   • Hydraulic Hoses and Fittings: These components connect the various parts of the hydraulic system. The hoses need to be able to withstand high pressure and have good flexibility to allow for the movement of the hydraulic cylinders. The fittings ensure a leak - proof connection between the hoses and other hydraulic components.
2. Platen and Mold System
   • Platens: The upper and lower platens are the main components that apply pressure to the mold and rubber material. They are usually made of high - quality steel with good heat - conducting properties if the press has a heating function. The surface of the platens is machined to a high degree of flatness and smoothness to ensure even pressure distribution and a good - quality surface finish of the molded damping plate.
   • Mold: The mold is custom - designed according to the specific requirements of the rubber damping plate. It can have different shapes and structures, such as flat - plate molds for simple - shaped damping plates or more complex molds with grooves and protrusions for plates with special functions. The mold is usually made of steel and may have a coating to prevent the rubber from sticking and to improve the durability of the mold.
3. Control System
   • The control system of a modern rubber damping plate hydraulic molding press is often based on a Programmable Logic Controller (PLC). The PLC allows for precise control of the hydraulic system's operations, including pressure, speed, and position of the platens. The operator can input the desired molding parameters such as pressure setting, holding time (if needed), and cycle time through a touch - screen interface. The control system also monitors the actual operation status of the press and can provide alarms and error messages in case of abnormal conditions such as over - pressure, over - temperature (if applicable), or equipment malfunction.

1. High Precision Molding
   • The hydraulic system allows for accurate control of pressure and movement, ensuring that the rubber damping plate is molded to the exact shape and dimensions required. The even pressure distribution helps to produce plates with consistent thickness and quality, which is crucial for their performance in damping applications.
2. Versatility
   • By changing the mold, the press can produce a wide variety of rubber damping plates with different shapes, sizes, and functions. This versatility makes it suitable for different industries and applications. For example, in the automotive industry, it can produce damping plates for engine mounts, while in the construction industry, it can produce plates for vibration isolation of building structures.
3. High - Quality and Durability
   • If the press has a vulcanization function, the vulcanized rubber damping plates have enhanced mechanical properties. The cross - linked rubber structure provides better resistance to wear, tear, and deformation, making the plates more durable and longer - lasting. Even without vulcanization, the precise molding process helps to improve the quality of the plates, reducing the likelihood of defects such as air bubbles or uneven density.

1. Automotive Industry
   • Rubber damping plates produced by this press are used in engine mounts, transmission mounts, and suspension components. They help to reduce engine vibration and noise, improve ride comfort, and protect other vehicle components from damage due to vibration and shock.
2. Construction Industry
   • In buildings and infrastructure, the damping plates are used for vibration isolation of floors, walls, and machinery foundations. They can also be used in bridge bearings to reduce the impact of traffic - induced vibrations and seismic vibrations.
3. Industrial Machinery
   • In factories and industrial settings, the plates are used to dampen the vibration of heavy machinery such as presses, generators, and pumps. This helps to improve the working environment by reducing noise and protecting the machinery from premature wear and tear caused by excessive vibration.
