500 Ton Inverted Hydraulic Hot Press Machine For Rubber Automotive Parts Molding

Operation Structions for Plate Vulcanizing Machine:

1. Wear protective equipment when handling, and do not use wet gloves.
2. Preheat the plate before vulcanization, check for any impurities between the plate layers, and whether other parts are normal. -
3. Pressure gauges, thermometers should be sensitive and effective, according to safety and process conditions, strict control of steam pressure, oil pressure and vulcanization temperature.
4. When loading the vulcanization mold, the hand should not protrude into the flat plate to prevent hot hands and crushing. If the problem is found, it should be stopped. The mold used should be placed in a stable position to prevent falling and bruising.
5. After the operation is completed, cut off the power supply, close the water and air valve, and put the mold back to the designated place.

Plate Vulcanizing Machine Working Conditions:

1. First, the work process

• After the semi-finished product without vulcanization is loaded into the model, the model is placed in the gap between the two hot plates (for unmodeled articles such as tape and rubber sheets placed directly between the hot plates). The hydraulic medium (oil or water) is then passed into the hydraulic cylinder, and the plunger pushes the movable platform and the hot plate upward or downward, and pushes the movable plate to press the mold or the product. While performing the above movement, the heating medium is passed into the heating plate, so that the model (or product) obtains the pressure and temperature required for the vulcanization process, and after a period of time (vulcanization cycle), the product is vulcanized, and then the inside of the hydraulic cylinder is The hydraulic medium is removed, and the product can be taken out because the plunger is lowered by its own weight (or the hydraulic pressure of the double-acting cylinder).

2. Second, the working principle

• When the flat vulcanizing machine is working, the hot plate heats up the rubber and crosslinks the rubber molecules, and the structure changes from a linear structure to a mesh-like body structure, which is a product that can obtain certain physical and mechanical properties, but the rubber compound After being heated, it begins to soften, and at the same time, the water and volatile substances in the rubber compound are vaporized. At this time, the hydraulic cylinder is used to give sufficient pressure to make the rubber compound fill the model, and the formation of bubbles is restricted, so that the product structure is dense. To. If it is a tape laminate, the glue and the cloth can be firmly adhered. In addition, sufficient pressure is applied to prevent the phenomenon of overflow of the mold, lack of glue, and pores of the sponge.
