    摘要： A motor is driven in a state where the moving platen (22) of an injection molding machine is not mounted with a mold to protrude an ejector rod (27), and the driving current of the motor is measured for each predetermined protrusion position. Then, the moving platen (22) is mounted with a mold (28b) and the motor is driven to protrude the ejector rod (27), and the driving current of the motor is measured. It is determined that an ejector rod protrusion position where a difference between this measured current value and a current value stored in a data table becomes larger is the protrusion start position of an ejector pin.

    摘要： An aligning device whereby an injection nozzle (5) can be easily aligned with the sprue of a mold. A stationary platen (2) has a locating hole (3) formed therein and a tapered portion (4) continuous with the locating hole (3) and tapered in a direction such that the tapered portion (3) broadens toward the injection nozzle (5). An aligning jig (1) to be fitted into the locating hole (3) and the tapered portion (4) is prepared. The jig (1) has a recess (1c) formed in the center of an end face thereof and having a shape matching that of the distal end of the injection nozzle (5). The jig (1) is fitted into the locating hole (3), and the inj ection nozzle (5) is engaged with the recess (1c) to align the injection nozzle (5) with the axis of the locating hole (3). Since the mold is attached to the stationary platen (2) such that the axis of the sprue of the mold is aligned with that of the locating hole (3), the injection nozzle (5) becomes aligned with the sprue. The injection nozzle (5) can be easily and accurately aligned even while the mold is attached to the stationary platen (2) and also the mold and the injection cylinder (6) are heated to high temperature.

    摘要翻译： 一种对准装置，由此喷嘴可以容易地与模具的浇口对准。 固定压板具有形成在其中的定位孔和与定位孔连续的锥形部分，并且沿着使锥形部朝向喷嘴侧变宽的方向逐渐变细。 准备装配到定位孔和锥形部分中的对准夹具。 夹具具有形成在其端面中心的凹部，其形状与喷嘴的远端的形状相匹配。 将夹具装配到定位孔中，并且喷嘴与凹部接合以使注射喷嘴与定位孔的轴线对齐。 由于模具被附接到固定的压板上，使得模具的浇道的轴线与定位孔的直线的轴线对齐，所以注射喷嘴与浇口对准。 即使在模具附接到固定压板上的同时，模具和注射缸也被加热到高温，注射喷嘴也可以容易且准确地对准。

    摘要： A tetragonal prism having a rectangular cross section is attached, as a linear motor movable section (8), to a moving plate (6) to which a screw (3) is attached rotatably and also immovably in an axial direction. A magnet (9a-d) is attached to each surface of the movable section (8). A hole section is provided in an outer frame (10). A linear motor coil (13a-d) is provided on the linear motor fixed section (12a-d) so that it may face the magnet (9a-d) on the surface of the movable section (8). A screw shaft is rotated by a motor through a measuring shaft penetrating a center of the movable section (8). By driving the linear motor comprising the magnet (9a-d) and the coil (13a-d) corresponding to each other, the screw (3) is moved and injected in an axial direction. The fixed section (12a-d) is detachable and a gap between the magnet (9a-d) and the coil (13a-d) can be easily adjusted.

    摘要： A support member (10) is fixed to the base (40) of a horizontal injection molding machine. The support member (10) and a stationary platen (1) fixed to the base (40) are connected by means of connecting members (11). In nozzle touch operation, an injection nozzle (36) of an injection unit (20) presses against the stationary platen (1). Although this pressing force of the injection nozzle (36) urges the stationary platen (1) to fall over, the connecting members (11) and the support member (10) prevent the stationary platen (1) from falling down.

    摘要： A fixed platen (2) and a rear platen (1) of an injection molding machine are connected to each other via tie bars (4). A coil spring (7) is disposed between the tie bar (4) and the rear platen (1) such that the rear platen (1) is urged in a direction away from the fixed platen (2). A mold thickness adjusting member such as a nut (10) is also provided for causing the rear platen (1) to move along the tie bar (4) toward the fixed platen (2) against the resilience of the urging means (7), thereby to adjust the mold thickness provided by the fixed platen (2), a movable platen (3), and attached fixed and movable dies (5a, 5b).

    摘要： An injection molding machine comprises a connecting member (10) formed by an upper plate portion (10a) and a side plate portion (10b). One end of the upper plate portion (10a) is fixed to a fixed platen (2) of the injection molding machine, and a lower end of the side plate portion (10b) is fixed to a base frame (1) to which the fixed platen (2) is fixed. This connecting member (10) prevents the fixed platen (2) from being tilted when a nozzle touch force is applied thereto from an injection apparatus (3).
