Injection moulding machine

摘要

The second mold platen (2) has no nozzle penetration. The axis (19) of the second injection unit includes an acute angle (alpha ) with the main machine axis (10). The nozzle (22) of the second injection unit (15), when in the injection position, lies against the mold, at a point remote from the machine axis (10). The support structure (14) for the second injection unit is held on the end plate (4). The angle alpha is preferably between 30[deg] and 50[deg]. The machine accommodates the second mold half (23), on the second platen (2). The mold (12, 25) is offset relative to the machine axis, towards the second injection unit (15), and overlaps beyond the corresponding edge of the second platen. The injection channel of the second injection unit discharges into in the overlap region of the second mold half. Discharge takes place at a contact surface (26) which is appropriately inclined to the machine axis, and is at right angles to the axis (19) of the second injection unit. The second platen (2) includes an edge recess for the second injection unit. Two second injection units are arranged in tandem. The support structure of the second injection unit is supported by linear guides (17) on the end plate (4). A number of second injection units may be arranged on different sides of the platen. In the space enclosed by the support structure of the second injection unit, a suction tank (27) for hydraulic fluid is fitted. The support structure (14) of the second injection unit is a console (13) fitted to the second platen. The first platen is fixed.
