MOULD FOR THE PRODUCTION OF ELASTIC BELLOWS FOR FLUID DOSING VALVES, PRODUCTION METHOD THEREOF AND BELLOWS THUS PRODUCED

摘要

The invention relates to a mould for the production of elastic bellows for fluid dosing valves, the production method thereof and the bellows thus produced. The inventive mould comprises a lower body and an upper body which is used to close the mould and which can move vertically, such that the upper part of said lower body is provided with two transversely-sliding mould assemblies bearing each of the mould areas that correspond respectively to each half of the outer profile of the bellows to be produced. The aforementioned mould assemblies can be moved in the active phase until they surround a core which is integrated into the lower mould. The outer shape of the upper part of the core corresponds to the bellows and said core is integrated into the lower mould such that it can rotate. The aforementioned core comprises an axial cooling chamber which is connected to a tubular conduit that is in turn connected to a lower mobile plate of the assembly of the lower mould.
