PURPOSE:To provide an aftermixer for reaction type injection molding which can obtain sufficiently satisfactory mixing effects of two liquids and which can prevent production of external appearance defects of a molding as well as improve its strength by placing each pair of mixing ports at inclination of angles in a specific range against at outlet port. CONSTITUTION:Several pairs of mixing ports 7, which are provided communicating with branched inlet passages 6' and 6'' in an aftermixer 2, are placed so as to have inclinations of 40-60 deg. with respect to the outlet port 8. The flowing out directions of the two liquids flowing as shown by arrows suddenly change twice, so that they are repeatedly provided with sufficient stirring action. In addition, if each pair of mixing ports 7 are placed so as to face to each other, the two liquids collide with each other there and are more uniformly mixed. |
