Twin injection molding machine including two injection devices

A twin injection molding machine comprising:

• a mold clamping device configured to clamp a mold, the mold clamping device comprising a fixed platen, a mold clamping housing, and a movable platen movable between the fixed platen and the mold clamping housing;
• and
• first and second injection devices each comprising:
• a heating cylinder;
• a screw disposed in the heating cylinder;
• and
• a screw driving device comprising driving system components and configured to drive the screw,
• wherein the first and second injection devices are disposed symmetrically with respect to a machine center line of the mold clamping device,
• wherein the driving system components provided in the screw driving device of the first injection device and the driving system components provided in the screw driving device of the second injection device are each disposed on the outward side of each respective injection device corresponding to a side away from the machine center line in the respective screw driving devices, the driving system components being configured to drive the screw of each the first and second injection devices in an axial direction of the first and second injection devices and rotate the screw of each the first and second injection devices, and
• wherein the twin injection molding machine further comprises:
• a first bed on which the first injection device is mounted;
• and
• a second bed on which the second injection device is mounted, the first bed and the second bed being separable from each other,
• wherein the first and second injection devices each comprise a movement mechanism configured to move the respective one of the first and second injection devices in a direction of approaching or being separated from the mold clamping device,
• wherein each movement mechanism comprises a piston cylinder component,
• wherein a first end portion of each piston cylinder component is fixed to the fixed platen and a second end portion of each piston cylinder component is fixed to a fixing member positioned further rearward than a rear end portion of the heating cylinder of each of the first and second injection devices, the fixing member being a frame of the screw driving device of each of the first and second injection devices, and
• wherein the driving system components of each of the first driving device and the second driving device comprises a plurality of hydraulic accumulators on the outer side of each respective injection device corresponding to the side away from the machine center line in the respective screw driving devices and configured to drive the screw of each the first and second injection devices in the axial direction of the first and second injection devices.
