Title:
射出成形機、制御盤及び冷却ユニット
Document Type and Number:
Japanese Patent JP7305403
Kind Code:
B2
Abstract:
A control unit (7) of an injection molding machine (1) includes a motor driving element (9) disposed in an internal space of the control unit housing (71), and a cooling unit (8) for cooling the motor driving element (9). The cooling unit (8) includes a flow path member (8) including a heat sink (81c) thermally connected to the motor driving element (9), and at least one first fan (F) forming a flow path (82) together with at least the flow path member (8), and configured to generate a first airflow flowing through the flow path (82) . The flow path (82) has an inlet (82a) in a first side surface portion (71b) of the control unit housing (71), has an outlet (82b) in a second side surface portion (71e) of the control unit housing (71), and is configured so that an operation of the first fan (F) prevents the first airflow flowing in the flow path (82) from flowing out to the internal space of the control unit housing (71).
