Abstract

A method for detachably attaching a linking unit, including an end with a hole and a slit, to a mold, the method comprising inserting a first attachment member connected to the mold through the hole; and inserting a second attachment member connected to the mold through the slit, wherein the linking unit is detached from the mold by moving the linking unit in a direction opposite to a direction in which the slit is formed in a state where the first attachment member is disconnected from the mold and the second attachment member remains connected to the mold.

Claims (12)

1. An injection molding system comprising:

at least two molds;

an injection molding machine;

at least one conveyor device configured to convey the at least two molds to/from the injection molding machine;

a linking unit configured to connect the at least two molds, wherein the linking unit comprises a first connection member for connecting to a first mold of the at least two molds and a second connection member for connecting to a second mold of the at least two molds,

wherein, with the first mold connected to the first connection member and the second mold connected to the second connection member, movement of the linking unit moves both the first mold and the second mold,

wherein the first connection member includes a slit configured to receive an attachment member for connecting the linking unit and the first mold, and

wherein the slit includes a shape such that a connection between the linking unit and the first mold established by the attachment member is released based on movement of the first connection member.

2. The injection molding system of claim 1 , wherein the slit is a straight shape, and the connection between the linking unit and the first mold established by the attachment member is released based on linear movement of the first connection member.

3. The injection molding system of claim 1 , wherein the slit is a curved shape, and the connection between the linking unit and the first mold established by the attachment member is released based on rotation of the first connection member.

4. The injection molding system of claim 1 , wherein the first connection member comprises at least one hole each configured to receive at least one attachment member for connecting the linking unit and the first mold.

5. The injection molding system of claim 1 , wherein the first connection member comprises at least one pin for limiting movement of the first connection member in at least one direction other than a direction based on the shape of the slit.
