Abstract

An injection molding apparatus includes: a molding mold 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; a nozzle in which a flow path that guides the molding material to the gate is formed; and a first cooling plate which is detachably attached to an opposite-side surface of the movable mold from a surface to be in contact with the fixed mold and which is provided with a first cooling mechanism therein, and the first cooling mechanism cools the molding material in the cavity portion.

First claim

What is claimed is:

1 . An injection molding apparatus, comprising:
a molding mold 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; a nozzle in which a flow path that guides the molding material to the gate is formed; and a first cooling plate which is detachably attached to an opposite-side surface of the movable mold from a surface to be in contact with the fixed mold and which is provided with a first cooling mechanism therein, the first cooling mechanism cooling the molding material in the cavity portion.

2 . The injection molding apparatus according to claim 1 , further comprising:
a second cooling plate which is detachably attached to an opposite-side surface of the fixed mold from a surface to be in contact with the movable mold and which is provided with a second cooling mechanism therein, the second cooling mechanism cooling the molding material in the cavity portion.

3 . The injection molding apparatus according to claim 1 , further comprising:
a control unit that acquires feature data representing a feature of the molding mold and selects a cooling plate corresponding to the feature data as the first cooling plate from a plurality of types of cooling plates having different cooling mechanism structures.

4 . The injection molding apparatus according to claim 3 , wherein
the feature data includes data representing a size of the cavity portion, a type of the molding material, molding accuracy, or cycle time.

5 . The injection molding apparatus according to claim 3 , further comprising:
a display unit that displays information indicating the cooling plate selected by the control unit.

6 . The injection molding apparatus according to claim 1 , wherein
vertical and horizontal dimensions in an outer shape of the first cooling plate and vertical and horizontal dimensions in an outer shape of the movable mold are unified.

7 . 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.

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