Abstract
Abstract The injection block structure for feeding molten thermoplastic material into molds, comprises modular elements (1,2,2a,3,3a,4,5) in mutually interchangeable association channels (6), extend through the interiors of the modular elements (1,2,2a,3,3a,4,5) and are adapted for directing the molten thermoplastic material to the molds. In combination with the modular elements (1,2,2a,3,3a,4,5), means of heating (7,8) the thermoplastic material are provided, which are housed within the channels (6).
