Patent ID: 6851946

Claim:
A hot runner manifold system for an injection mould for simultaneous injection moulding of several parts or of large parts, comprising a multiplicity of injection orifices ( 24 ), which are designed for delivering injection moulding compound substantially simultaneously under high pressure and at high temperatures into specified mould zones, the mould zones being provided at least partially on main manifolds ( 11 , 12 , 13 , 14 ) that are separated from one another, which main manifolds have hot runners ( 17 , 19 , 21 , 23 ) and are connected via at least one pre-manifold ( 2 ), which pre-manifold has hot runners ( 4 , 7 ), to a sprue ( 1 ) for receipt of the injection moulding compound, wherein at least one part of pre-manifold ( 2 ) is arranged between adjacent main manifolds ( 11 , 12 , 13 , 14 ), with the hot runners ( 7 , 17 ) of the pre-manifold ( 2 ) and of the main manifolds ( 11 , 12 , 13 , 14 ) opening through lateral surfaces of pre-manifold ( 15 ) and a main manifold ( 25 ) that face one another and are in contact with one another, with the main manifolds ( 11 , 12 , 13 , 14 ) and pre-manifolds ( 2 ) pressed together firmly and tightly at the lateral surfaces by lateral spring elements ( 6 ), where the spring elements ( 6 ) permit a limited movement of the main manifolds ( 11 , 12 , 13 , 14 ) by overcoming the force of a spring element ( 6 ).
