Injection molding apparatus, cooling plate for injection molding apparatus, and cassette mold

A cooling plate for injection molding apparatus, the injection molding apparatus including:

• a fixed mold in which a gate into which a molding material flows is formed;
• and
• a movable mold in which a cavity portion is formed and which is separated from the fixed mold when the mold is opened, and
• the cooling plate comprising:
• a first cooling mechanism therein, the first cooling mechanism cooling the molding material in the cavity portion, wherein
• the cooling plate is detachably attached to an opposite-side surface of the movable mold from a surface to be in contact with the fixed mold.
