Injection molding system, injection molding machine, and peripheral device

An injection molding machine connectable to a peripheral device including a movable hand clamp, a second driver that moves the movable hand clamp, and a second output that outputs second relative position information on a relative position of a second movement position of the movable hand clamp in relation to a second reference position of the peripheral device, the injection molding machine comprising:

• a movable mold;
• a first driver that moves the movable mold;
• a frame on which the movable mold and the first driver are mounted;
• a first controller that is configured to execute a program that when executed, calculates a first relative position information on a relative position of a first movement position of the movable mold in relation to a first reference position of the injection molding machine;
• and
• a first output that is configured to execute a program that when executed, outputs the first relative position information calculated by the first controller to the peripheral device, wherein
• the injection molding machine further includes a first connector connected to the peripheral device and directly attached to the frame,
• the peripheral device further includes a second connector connected to the injection molding machine and configured to receive the first connector,
• the first reference position is a predetermined position of the first connector on the frame,
• the second reference position is a position of the second connector directly adjacent to the first reference position,
• an inter-reference relative position on a relative position between the first reference position of the injection molding machine and the second reference position of the peripheral device is the same position, and
• the first controller is configured to calculate inter-drive-unit relative position on a relative position between the first movement position of the first driver and the second movement position of the second driver on the basis of the first relative position information and the second relative position information in order to prevent the movable hand clamp from damaging the peripheral device by contact, or to prevent the movable hand clamp from damaging the injection molding machine by contact.
