The impact of rubber product design on demoulding

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. 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 and the internal tendons and the slope of the place such as Trail; There are also products have no slope at all, 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 hinder the release of the mould. If you increase the slope of the mould release, you can obviously reduce this resistance.
This resistance can be reduced if the mould release slope is increased, and defects such as tearing can be avoided due to the lack of slope. 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 °.
