Rubber product design directly affects the release performance of the product, so the product design should meet the requirements of the product easy to release the mould. Product design in the main factors affecting the release of the mould is the release of the slope, in order to open the mould to take out the product, in the vertical parting surface products inside and outside the surface should be equipped with sufficient demoulding slope. Some products have demoulding slope, but the value is too small Some products only have the slope of the outer surface, ignoring the inner surface as well as the internal tendons and Yi and other places in the slope; there are also products simply do not have the slope, these products have brought difficulties in demoulding. Products out of the oven, due to product cooling and centripetal contraction, in the core or pin to produce a large holding force, and impede the demoulding. If you increase the demoulding slope, you can significantly reduce this resistance, but also to avoid tearing and other defects caused by the lack of slope of the product. The mould release slope is related to the shape and thickness of the product, usually determined by experience, the general product slope is between 1°~3°.
