Abstract
The invention relates to a mold base for a system for injection molding of plastic parts, in particular for automotive body and/or structure components, preferably for baffle and/or reinforcing structures, comprising at least one, namely first, bridge manifold with at least a first and a second bridge manifold opening for feeding material to at least a first and a second sub-manifold of at least one mold insert assembly and at least a first and a second control valve, wherein the first control valve is provided and configured for controlling the material feed through the first bridge manifold opening and the second control valve is provided and configured for controlling the material feed through the second bridge manifold opening.
Claims23
A modular system for injection molding of plastic parts, the system comprising:
- at least one mold insert assembly comprising at least a first and a second sub-manifold;
- and
- a mold base comprising (i) a first bridge manifold with at least a first and a second bridge manifold opening for feeding material to the first and the second sub-manifold of the at least one mold insert assembly, and (ii) at least a first and a second control valve, the first control valve being provided and configured for controlling the material feed through the first bridge manifold opening and the second control valve being provided and configured for controlling the material feed through the second bridge manifold opening,
- wherein the first and the second sub-manifold of the at least one mold insert assembly are configured to be connected to the first or second bridge manifold openings,
- the mold insert assembly is configured to be detached from the mold base as a module in the modular system, and
- the mold insert assembly includes at least one ejector and at least one ejector plate.
