First, the area of the mold must be less than the area of the plate, but not too small;
Second, after the mold is placed on the plate, it should be kept in the center position as far as possible, so that the plate vulcanization machine is working under positive load to avoid partial load. (This is because when the mold is placed in the center of the plate, the pressure generated by the hydraulic cylinder is evenly distributed on the symmetric points of the plate vulcanization machine, at this time, the frame itself forms a closed force system, that is, the generated force is all borne by the plate vulcanization machine itself, not all of the action on the foundation, and the deformation of the components is also symmetrical. If the mold is biased, the plate vulcanization machine will be subject to a partial load, which is the uneven force of the plate vulcanization machine itself, the deformation is not uniform, and will produce an additional couple, so that the deformation of the column is inconsistent. Cause the mold to fly side increase, while shrinking, so that the product thickness error, at the same time, make the machine local force complex, even overload damage, especially the plunger load sealing ring increased force, reduce the service life, so from the operation is not allowed, therefore, in the use of multi-mode vulcanization, should pay attention to the thickness of the mold consistent and mold layout, To prevent pressure deviation or partial mold pressure loss.)
