In a three-plate injection-molding machine comprising a nozzle plate, a movable second mold clamping plate, a movable end plate, a closing unit that acts between the end plate and the second mold clamping plate, and a turning unit arranged between the nozzle plate and the second mold clamping plate, rails extend between the nozzle plate and the end plate. The mold-half carrier of the turning unit is supported on a support structure so that it can be rotated about an axis transverse to the machine axis, which support structure forms the abutment for the mold-half carrier rotary drive. The weight of the support structure and mold-half carrier of the turning unit is transferred into the machine bed by means of linear guides, and a substantial part of the reaction torque applied to the support structure is transferred to one of the rails by means of one supporting guide.
An injection-molding machine in three-plate design with a machine bed (1), a first mold-clamping plate (2), which is provided with a nozzle penetration and with which a first injection unit (SE 1) is associated, an end plate (E), a second mold-clamping plate (3), which can be moved parallel to a machine axis (M), is braced via a closing assembly (S) against the end plate (E) and with which a second injection unit (SE2) is associated, a plurality of bars (H) extending between the first mold-clamping plate (2) and the end plate (E), and a turning unit (6), which comprises a mold-half carrier (9) and is disposed between the first mold-clamping plate (2) and the second mold-clamping plate (3), wherein the end plate (E) is braced on the machine bed (1) such that it can be displaced along the machine axis (M) and the mold-half carrier (9) is mounted on a support structure (7) to rotate around an axis of rotation (D) oriented transversely relative to the machine axis (M), the said support structure forming an abutment for a mold-half-carrier rotary drive, wherein the weight of the support structure (7) and of the mold-half carrier (9) of the turning unit (6) is transferred via linear guides (11) directly from the support structure (7) into the machine bed (1) and at least a substantial part of a reaction torque exerted on the support structure (7) during rotational acceleration of the mold-half carrier (9) is transferred via at least one bracing guide (16) into at least one of the bars (H),
