## Abstract

The present disclosure relates to a casting apparatus including a support block, a die provided on one surface of the support block and configured to form a cavity in cooperation with the support block, and an insert member provided to be movable relative to the support block and configured to selectively move between a first position at which the insert member is received in the cavity and a second position at which the insert member is extracted out of the cavity, thereby obtaining an advantageous effect of simplifying a structure and a manufacturing process.

## Claims

### Claim 1

A casting apparatus comprising:
a support block;
a die provided on one surface of the support block, the die being configured to form a cavity in cooperation with the support block; and
an insert member movable relative to the support block and configured to selectively move between a first position at which the insert member is received in the cavity and a second position at which the insert member is extracted out of the cavity.

### Claim 2 (depends on 1)

The casting apparatus of claim 1, wherein when the insert member moves from the first position to the second position, a molded body formed in the cavity is supported by the support block, and the insert member is separated from the molded body.

### Claim 3 (depends on 2)

The casting apparatus of claim 2, wherein the support block further comprises a through hole, and the insert member moves from the first position to the second position along the through hole.

### Claim 4 (depends on 3)

The casting apparatus of claim 3, comprising:
a restriction unit configured to selectively restrict the insert member disposed at the first position.

### Claim 5 (depends on 4)

The casting apparatus of claim 4, wherein the restriction unit comprises:
a first restriction block provided on the other surface of the support block and configured to move between a first closed position at which the first restriction block closes the through hole and a first opened position at which the first restriction block opens the through hole; and
a second restriction block provided on the other surface of the support block and configured to move between a second closed position at which the second restriction block closes the through hole and a second opened position at which the second restriction block opens the through hole.

### Claim 6 (depends on 5)

The casting apparatus of claim 5, comprising:
a holder member configured to support the first restriction block and the second restriction block such that the first restriction block and the second restriction block are movable.

### Claim 7 (depends on 1)

The casting apparatus of claim 1, wherein the die comprises:
a first mold configured to define one part of a wall surface of the cavity; and
a second mold provided to be movable toward and away from the first mold and configured to define the other part of the wall surface of the cavity.

### Claim 8 (depends on 1)

The casting apparatus of claim 1, comprising:
a transfer unit configured to transfer the molded body formed in the cavity;
wherein when the die and the insert member are separated from the molded body in a state in which the transfer unit holds the molded body, the transfer unit transfers the molded body to a predetermined ejected position.

### Claim 9

A casting method comprising:
disposing an insert member in a cavity provided in a die;
forming a molded body by injecting molten metal into the cavity;
separating the die from the molded body;
separating the insert member from the molded body by moving the insert member out of the cavity; and
transferring the molded body to a predetermined ejected position.

### Claim 10 (depends on 9)

The casting method of claim 9, wherein the die is provided on one surface of a support block and forms the cavity in cooperation with the support block, and wherein in the separating of the insert member from the molded body by moving the insert member out of the cavity, the molded body is supported by the support block, and the insert member is moved and separated from the molded body.
