Injection molding device

An injection molding device comprising:

• a housing including a door;
• an injection molding machine stored in the housing;
• a detection section configured to detect whether the door is open or closed or to detect intrusion of foreign matter into the housing;
• and
• a control section, wherein
• the injection molding machine includes
• a support section for supporting a die-casting mold having an upper mold and a lower mold,
• an injection unit configured to inject a molding material toward a cavity defined by the upper mold and the lower mold, and
• a mold clamping device including a mold clamping motor that drives the die-casting mold,
• the injection unit, the upper mold, and the lower mold are disposed in this order in a vertical direction from above, while in a supported state in which the die-casting mold is supported by the support section,
• in the supported state, the control section controls voltage applied to the mold clamping motor and performs mold-clamping and mold-opening of the upper mold and the lower mold by either moving the injection unit and the upper mold along the vertical direction or by moving the lower mold along the vertical direction,
• the mold clamping device further includes a first brake section that, when application of voltage to the mold clamping motor is stopped, regulates movement of the injection unit and the upper mold in the vertical direction or movement of the lower mold in the vertical direction, and
• when the detection section detects that the door is open or detects intrusion of foreign matter, the control section stops application of voltage to the mold clamping motor.
