摘要： When a metering process is started, a screw rotates at a preset rotating speed, thereby carrying out back pressure control to keep the pressure of a resin at a preset pressure, and retreats. When the screw is located near a preset metering completion position, the control mode is switched to positioning control for the preset metering completion position, and a screw rotation stop command is outputted. The screw overruns for some distance before its rotation stops after it retreats and stops at the preset metering completion position. A resin quantity for the overrun is corrected to obtain a preset metered resin quantity by reversely rotating the screw by a rotational amount corresponding to the overrun.

摘要： A mold is mounted with a locating ring mated into a hole in a stationary platen. A distance measuring unit is disposed to the side of the injection nozzle. The distance A between the sprue hole and the outer circumference of the locating ring and the distance B between the distance measuring unit and the outer circumference of the locating ring are both known. The distance C between the central axis of the nozzle hole and the side of the injection nozzle is also known. If the distance D to the side of the injection nozzle is measured by means of the distance measuring unit, the displacement between the central axis of the sprue hole and the central axis of the nozzle hole is obtained by calculating {(A+B)−(C+D)}. The injection nozzle is centered by being moved manually or automatically by the amount corresponding to the displacement.

摘要： The present invention provides an injection unit having a structure designed for easier machining of a resin guiding hole located in a front plate constituting the injection unit in tile injection molding machine, as well as for reducing tile thermal influence of the heating cylinder and tile plate body on the resin guiding hole. The front plate of the injection unit has a nose member (5), in which a hopper (6) and the heating cylinder (7) are attached, and the plate body (4) linked to a tie bar (10), which are components separated from each other. The injection unit is constructed by joining the heating cylinder (7), the nose member (5) and the plate body (4) to one another through air gaps (23, 24, 28, 29) formed between these components.

摘要： A screw is rotated at a set speed and retreated by performing back pressure control for keeping a resin pressure at a set pressure. When the retreat position of the screw reaches a change point set nearby a set metering completion position, the back pressure control for keeping the resin pressure at a set resin pressure is stopped. A command for positioning the screw at a metering completion position is output to position the screw at the metering completion position. At the same time, when a screw position reaches the change point, the screw is reversed by a set value at a set speed.

摘要： An excessive load detection device for an injection molding machine capable of detecting an excessive load exerted on the injection screw when the screw is driven with resin remaining unmolten in the heating cylinder. An output torque of the servomotor for axially moving the screw is limited to a predetermined value by a torque limiter and the screw is driven to move forward in a direction of injection by a predetermined amount at a predetermined velocity. If reference time elapses before the axial motion of the set amount is completed or a position deviation exceeds a reference value, it is determined that the remaining resin has low fluidity to cause an excessive load on the screw and an alarm is issued. When the axial motion of the screw is completed without an alarm, the screw is moved backward and forward alternately predetermined times. A servomotor for rotating the screw is driven in the same manner to detect an excessive load on the screw. Since the excessive load on the screw is directly detected, the excessive load is securely detected.
摘要翻译：一种用于注射成型机的过度负载检测装置，其能够检测当在加热缸中树脂保持不熔的情况下驱动螺杆时施加在注射螺杆上的过大的负荷。用于轴向移动螺杆的伺服电动机的输出转矩通过扭矩限制器被限制在预定值，并且螺杆被驱动以在预定方向上以预定速度在注射方向上向前移动预定量。如果在设定量的轴向运动完成或位置偏差超过参考值之前经过参考时间，则确定剩余树脂具有低流动性，从而导致螺钉上的过大负载并发出报警。当螺杆的轴向运动在没有报警的情况下完成时，螺杆被交替地向前和向前移动预定时间。用于旋转螺钉的伺服电动机以相同的方式被驱动以检测螺杆上的过大负载。由于直接检测到螺钉上的过大负载，因此能够可靠地检测过载。

摘要： A screw linkage structure in an injection molding machine comprises a screw (8) having at its base a spline portion (11), a spline bush (9) for receiving the spline portion (11), a screw sleeve (4) having a front surface to which the spline bush (9) is secured, and a retainer (10) serving to prevent the screw (8) from being disengaged from the spline bush (9). The spline portion (11) formed on the screw base is fitted into the spline bush (9) and includes an annular groove (15). The spline bush (9) has a through-hole acting as a retainer attachment hole (16) at the position corresponding to the annular groove (15) of the screw base to be fitted thereinto. The retainer (10) is then inserted into the retainer attachment hole (16) of the spline bush (9) until its leading edge reach the annular groove (15) of the screw base, thereby preventing the screw (8) from being disengaged from the screw sleeve (4).
