ABSTRACT:
For injection molding of tooth brushes from two different molding material components with tufts of bristles incorporated in the head portions of the brush bodies a molding machine is proposed which includes a tuft loading station, a first injecting station associated with the first material component and a second injecting station associated with the second material component. In one or each injecting station, the stationary molding block has a recess, and a movable mold insert part fits into this recess to complete the stationary mold block. The movable mold insert part is provided with tuft insertion holes and can be transferred to the tuft feeding station where tufts of bristles are loaded into the tuft insertion holes so that they have their inner ends projecting into the mold cavity portion defined by the movable mold insert part. Production of tooth brushes is a continuous sequence of tuft loading and injecting steps.
