摘要： An injection unit of an injection molding machine is capable of preventing displacement of an axis of a heating barrel (11) and of an axis of an injection screw (12), and facilitating a nozzle axis adjustment. A front plate (1) supporting a heating barrel (11) is fixed to a base (10) with a height-adjusting mechanism (13) located in-between. A rear plate (2) is connected to the front plate (1) by connecting members (3) symmetrically arranged. The injection screw (12) inserted in the heating barrel (11) is rotatably supported by a pusher plate (5) to which a ball nut (7) is fixed. A ball screw (8) engaged with the ball nut (7) is rotatably supported by the rear plate (2). The pusher plate (5) is supported and guided by a support/guide member (6) and moves forward, to inject resin, by rotation of the ball screw (8). The support/guide member (6) is supported by a supporting member (4) fixed to the front plate (1). Being independent of the connecting members (3) that are deformed to be elongated at a time of injection, the pusher plate (5) remains uninfluenced, making it possible to prevent displacement of the axes of the heating barrel (11) and of the injection screw (12).

摘要： A driven pulley (4) is attached via a bearing (3) to a first housing (1) that can move in the axial direction of injection.
This driven pulley is connected to a rotation transmitting member (5) by a spline coupling (17). An injection screw (8) is fastened to this rotation transmitting member (5). Furthermore, this rotation transmitting member (5) is attached to a second housing (7) via a bearing (6) so as to move in the axial direction. The first housing (1) and second housing (7) are respectively fastened to the outer ring part (2a) and inner ring part (2b) of a load detection device (2). Since the first (1) and second (7) housings are capable of relative movement in the axial direction of an injection shaft, no pre-load is generated in the load detection device (2).
Movement of the driven pulley (4) caused by the tension of the mounted belt is checked by a bearing. No frictional force is generated in the spline coupling part (17). Accordingly, the resin pressure that is applied to the injection screw (8) can be accurately measured by the load detection device (2).

摘要： An injection unit of an injection molding machine is provided, in which an offset load is not applied to a ball screw (6) for moving an injection screw (13). A pusher plate (5) is provided that is moved while being guided by guide rods (4) extending between front and rear plates (2, 3), and that supports the injection screw (13) and the ball screw (6) so that they are rotatable but axially immovable with respect to the pusher plate (5). The ball screw (6) is threadedly engaged with a ball nut (7) mounted to the rear plate (3) so as to be unrotatable and axially immovable with respect to the rear plate (3). A support plate (20) is coupled through coupling rods (21) to the pusher plate (5). The ball screw (6) has another end supported on the support plate (20) in a rotatable but axially immovable manner with respect to the support plate (20). The pusher and support plates (5, 20) are supported on a base by linear motion guides (22, 23). The ball screw (6) is supported at its two ends by the pusher and support plates (5, 20) so as not be tilted, whereby no offset load is produced and the service life of the injection unit is prolonged.

摘要： A safer safety door, provided at low cost and imposing little burden on an operator. A primary safety door (10a) with a top and a secondary safety door (10b) are provided on a ciamping unit. The primary safely door and the secondary safety door abut each other at abutting portions (18a,18b) provided on each safety door. The secondary safety door has an engaging member (11) that swings along a guide member (12). The engaging member (11) has a hinge (11d) bent in one direction. When both safety doors are closed, the primary safety door (10a) can be freely opened and closed independently. When the secondary safety door (10b) is opened, both safety doors are linked together and move as a single body. In the state where the primary and secondary safety doors are opened separately, when the prirnary safety door (10a) is moved to be closed, the hinge member (11d) bends and both safety doors are linked together as a unit.

摘要： An outer ring (3a) of a load cell (3) is mounted on a pusher plate (1). A rotation transmission member (4) mounting portion (3e) is extended from an inner ring (3c) of the load cell (3), and a rotation transmission member (4) connected to an injection screw (18) is supported by the rotation transmission member mounting portion (3e) through a bearing (5). A resin pressure applied to the injection screw (18) is applied to the inner ring (3c) of the load cell (3) through the rotation transmission member (4) and the rotation transmission member mounting portion (3e), and the distortion generating portion (3b) is distorted to detect the resin pressure. A rotation deflection of the bearing generated when the rotation transmission member is rotated by external power is absorbed by the thin portion (3d) (necking portion) formed on the rotation transmission member mounting portion (3e).

摘要： The invention provides an injection molding machine injection unit that eliminates adverse effects on the load cell (3) of belt tension due to belt drive. A load cell (3) that detects resin pressure is mounted on a pusher plate (1) and a rotation-transmitting member (4), on which an injection screw (17) is fixedly mounted, is axially supported by an inner annular part (3b) of the load cell. The shaft (7) of a pulley (9) is axially supported on the pusher plate (1) and coupled by splines to the rotation-transmitting member (4). A screw rotation motor (12) is mounted on motor mounts (2a) of a housing (2) mounted on the rear surface of the pusher plate (1). Tension on a belt run between the pulley (9) and a pulley (11) mounted on the motor output shaft concentrates a force at the base of the motor mounts (2a). However, the housing (2) is separate from the pusher plate (1) and fixedly mounted on the pusher plate (1) at a location other than that occupied by the base of the motor mounts (2a). Therefore, the belt tension does not adversely affect the load cell (3), thus enabling high-accuracy resin pressure detection.

摘要： A driven pulley (4) is attached via a bearing (3) to a first housing (1) that can move in the axial direction of injection.
This driven pulley is connected to a rotation transmitting member (5) by a spline coupling (17). An injection screw (8) is fastened to this rotation transmitting member (5). Furthermore, this rotation transmitting member (5) is attached to a second housing (7) via a bearing (6) so as to move in the axial direction. The first housing (1) and second housing (7) are respectively fastened to the outer ring part (2a) and inner ring part (2b) of a load detection device (2). Since the first (1) and second (7) housings are capable of relative movement in the axial direction of an injection shaft, no pre-load is generated in the load detection device (2).
Movement of the driven pulley (4) caused by the tension of the mounted belt is checked by a bearing. No frictional force is generated in the spline coupling part (17). Accordingly, the resin pressure that is applied to the injection screw (8) can be accurately measured by the load detection device (2).
