Abstract
A mold includes a mold body including a fixed mold and a movable mold movable toward or away from the fixed mold, a molding space defined by the fixed mold and the movable mold to accommodate a pipe therein, an injection opening through which a molten metal material is injectable into the molding space, a holding portion holding both of two ends of the pipe, and a movement restraint to prevent movement of the pipe in the molding space when the molten metal material is injected into the molding space.
Claims20
A mold, comprising:
- a mold body including a fixed mold and a movable mold movable toward or away from the fixed mold;
- a molding space defined by at least the fixed mold and the movable mold to accommodate a pipe therein;
- an injection opening through which a molten metal material is injectable into the molding space;
- a holding portion holding both of two ends of the pipe;
- and
- a movement restraint to prevent movement of the pipe in the molding space when the molten metal material is injected into the molding space.
A method for producing a cast item including a pipe and a metal body cast around the pipe, the method comprising:
- a preparation step of preparing a mold including a fixed mold, a movable mold movable toward or away from the fixed mold, a molding space defined by at least the fixed mold and the movable mold to accommodate the pipe therein, an injection opening through which a molten metal material is injectable into the molding space, a holding portion holding both of two ends of the pipe, and a movement restraint to prevent movement of the pipe in the molding space when the molten metal material is injected into the molding space;
- a placement step of causing the pipe to be held by the holding portion and placing the pipe in the molding space such that the pipe is in contact with the movement restraint;
- a mold clamping step of moving the movable mold toward the fixed mold to close the mold;
- a filling step of injecting the molten metal material into the molding space through the injection opening to fill the molding space with the molten metal material;
- and
- a removal step of moving the movable mold away from the fixed mold to open the mold and removing the cast item.
