The utility model relates to
injection molding machine technical field, concretely relates to a
raw material mixing hopper for
plastic injection molding machine, it includes
processing cylinder, is provided with mixing stirring subassembly in
processing cylinder, is provided with anti -blocking unloading component at
processing cylinder top, is provided with controllable
discharge capacity subassembly at processing cylinder bottom, the utility model discloses a mixing stirring subassembly is set up in processing cylinder, when
raw material enters processing cylinder, first, several
cutting blades in the uppermost region of the pivot scatter and break the
raw material that enters first, then several oblique rectangular plates promote the further mixing of raw material in processing cylinder, finally, the
spiral blade stirs and extrudes the raw material close to the bottom export, thereby can carry out all -round, multilevel stirring mixing to multiple raw materials, greatly improves the uniformity of raw material mixing, makes the quality of injection moulded product more stable, and the performance is more consistent.
