めることが困難である。2. Especially when the injection unit is placed vertically, it is effective in reducing the floor space occupied, but on the other hand, the ceiling height needs to be increased, and maintenance management including material input work is difficult. In addition, the injection unit is not only sensitive to vibrations caused by the opening and closing operations of the mold, but also has a vertical shape, so the inertia due to the screw's own weight is large, making injection difficult for precision molding. It is difficult to increase accuracy.

可能な射出成形機である。In order to achieve all of the above-mentioned objects, the present invention is an injection molding machine having a mold clamping device that opens and closes the mold by moving a movable mold horizontally forward and backward relative to a fixed mold. This is an injection molding machine that is equipped with an injection unit that is placed at a predetermined angle of inclination, and that this injection unit is rotatably locked by an actuator such as a hydraulic or pneumatic cylinder. This is an injection molding machine that has an injection unit with a nozzle attached to its tip that contacts the resin injection port of the mold at a substantially right angle to the direction in which the mold moves. Another configuration of the injection molding machine is that the injection unit is screwed onto an ai1e shaft attached to the upper part of the fixing member of the mold clamping device and can be adjusted in the vertical direction.

初に掲けたような欠点が解゛消された。As explained above, in the injection molding machine according to the present invention, the injection unit is placed above the mold clamping device approximately horizontally or at a predetermined inclination angle, so that the injection unit is placed in series with the conventional mold clamping device. In addition to reducing the floor space required compared to an injection molding machine with an injection unit installed vertically, the height of the machine can also be kept small compared to a machine with an injection unit installed vertically, resulting in a compact overall design. Furthermore, compared to equipment with a vertical injection unit, maintenance management such as loading raw materials is not only easier, but the vibrations caused by opening and closing the mold have a greater effect than conventional equipment, which made it unstable. However,
Since the injection unit and throat are horizontal as in the device of the present invention, the influence of vibrations is also reduced. As for the injection accuracy of Jt, there is no longer any variation due to the weight of the screw, so the drawbacks that were raised at the beginning have been eliminated.
