摘要

The injection molding device comprises a replaceable head (1) having a first locking means (8) and an injection molding block (2) having a second locking means (10). The locking means form a locking system for the replaceable head on the injection molding block. The replaceable head comprises an injection molding form with a cavity. The injection molding form is interchangeably arranged in the replaceable head. The first locking means on the replaceable head is a locking pin and the second locking means is a rotatable bolt, which has a locking groove for the locking pin. The injection molding device comprises a replaceable head (1) having a first locking means (8) and an injection molding block (2) having a second locking means (10). The locking means form a locking system for the replaceable head on the injection molding block. The replaceable head comprises an injection molding form with a cavity. The injection molding form is interchangeably arranged in the replaceable head. The first locking means on the replaceable head is a locking pin and the second locking means is a rotatable bolt, which has a locking groove for the locking pin. The device comprises an auxiliary locking means, which are formed on the replaceable head and on the injection molding block in the form of a bevel, and a drive (20), which is actuated by a lever to auxiliary locking mechanism. The drive is arranged on opposite side of the injection molding block as the replaceable head. A guiding groove for the first locking means is equipped at the injection molding block. A guiding pin is equipped on the injection molding block for inserting the replaceable head, which has an opening corresponding to the guiding pin. A connection is intended for the injection molding machine. A lever for the drive is arranged for actuating the locking system on the adjoining side of the injection molding block as the connection for the injection molding machine. The injection molding block comprises injection molding canals, which correspond to the cavity canals in the replaceable head. The replaceable head is aligned through the locking system on the correspondence of the injection molding canals with the cavity canals for injection molding block. A heating device is arranged for heating the injection molding block and/or the replaceable head. The injection molding block and/or the replaceable head is made of aluminum.
