Advantages of temperature control of mold temperature machine for flat vulcanizer
The flat vulcanizer mold temperature machine is also called the heat transfer oil heater. The flat vulcanizer temperature control mold temperature machine is used to control the temperature of the flat plate, which is used to adjust the equilibrium mold temperature of the mold, and it can heat up or cool down. The mold temperature machine uses a high thermal conductivity thermal medium to control the temperature of the mold in a very short time. After setting the thermal equilibrium temperature, the mold temperature function can automatically control its temperature within a very small error, and can maintain a constant value.
It is mainly used for the molding of flat products such as rubber sheets, tracks, carbon fiber polymers, etc. It has the characteristics of high pressure per unit area of the hot plate, safe and reliable equipment operation, and less maintenance. required pressure and temperature.
The uniformity of heating temperature is considered when the mold temperature machine is designed for the flat vulcanizer. Each hot plate is divided into multiple sections of heat transfer oil to enter and exit, and the temperature sensor on each layer of the hot plate and the temperature display on the PLC touch screen on the console, Pressure display and temperature and pressure over-limit alarm system, the mold temperature control machine has the ability to prompt the temperature deviation and pressure of each layer, so that the operator can take appropriate measures. The rubber flat vulcanizing machine is mainly used for vulcanizing flat tapes. The pressure per unit area is large, the equipment can be operated, reliable and less maintenance.
The design of the mold temperature machine of the flat vulcanizer requires that the mold temperature be controlled within the range of (±1°C). Therefore, the temperature control of the liquid running between the mold pipes must be precise, otherwise the purpose of mold temperature control will not be achieved. Plastic mold temperature machine generally has water temperature machine and oil temperature machine. The cooling method of the temperature controller is divided into direct cooling and indirect cooling. The indirect cooling method of the hot press mold temperature machine adopts the cooling circuit to be separated from the main circuit, while the direct cooling method of the temperature control machine, the cooling circuit directly participates in the main circuit. The water-carrying mold temperature machine usually adopts the direct cooling method. The oil-carrying mold temperature machine adopts the indirect cooling method because the water and oil cannot be mixed together during the heating process, and the method usually adopts the plate exchanger for cooling.
The working principle of the mold temperature machine of the flat vulcanizing machine is that the mold temperature controller controls a certain constant temperature when the flat vulcanizing machine is working, and its structure changes from a linear structure to a net-like body shape, which can be obtained with a certain physical machinery. The performance of the product, but after the rubber compound is heated, it begins to soften, and at the same time the water in the rubber compound. Parts and volatile substances need to be vaporized. At this time, rely on the hydraulic cylinder to give enough pressure to fill the mold with the rubber and limit the generation of air bubbles. Make the product structure dense.
