Mold device and injection molding system

An injection molding system comprising:

• a mold device including a fixed mold and a movable mold and forming a cavity space between the fixed mold and the movable mold when the fixed mold and the movable mold are clamped together;
• and
• an injection molding machine configured to inject a pre-heated molding material into the cavity space in the mold device,
• wherein the fixed mold includes a first mold piece that, when the fixed mold and the movable mold are clamped together, contacts the movable mold and forms a part of a wall surface of the cavity space,
• wherein the fixed mold or the injection molding machine includes:
• a first cooling part that is adjusted to a temperature lower than a temperature of the first mold piece observed at a time of injecting the molding material into the cavity space;
• and
• a first support part that movably supports one of the first cooling part and the first mold piece such that one of the first cooling part and the first mold piece relative to another one of the first cooling part and the first mold piece,
• wherein the first cooling part and the first mold piece are movable relative to each other, in both mold opening and closing directions, between positions at which the fixed mold and the movable mold are spaced apart and positions at which the fixed mold and the movable mold are in contact with each other,
• wherein the movable mold includes:
• a second mold piece that, when the fixed mold and the movable mold are clamped together, contacts the fixed mold and forms a part of the wall surface of the cavity space,
• wherein the fixed mold or the injection molding machine includes:
• a second cooling part that is adjusted to a temperature lower than a temperature of the second mold piece at a time of injecting the molding material into the cavity space;
• and
• a second support part that movably supports one of the second cooling part and the second mold piece relative to another one of the second cooling part and the second mold piece, and
• wherein the second cooling part and the second mold piece are movable relative to each other, in both of the mold opening and closing directions, between positions at which the fixed mold and the movable mold are spaced apart and positions at which the fixed mold and the movable mold are in contact with each other.
