Conveying apparatus for moving molds

An injection molding system comprising:

• an injection molding machine;
• and
• a conveying apparatus, wherein the conveying apparatus comprises:
• an actuator for conveying the mold;
• a first rotating body;
• and
• a second rotating body,
• wherein the first rotating body and the second rotating body are configured to support a bottom surface of the mold,
• wherein the first rotating body and the second rotating body assist in guiding conveyance of the mold by the actuator,
• wherein the first rotating body is positioned closer to a fixed platen of the injection molding machine in an axial direction of the first rotating body than the second rotating body, and
• wherein an improvement of the conveying apparatus is that a length in an axial direction of the second rotating body is longer than a length in the axial direction of the first rotating body.

A method for manufacturing a molded product using a conveying apparatus including a first rotating body and a second rotating body, the method comprising:

• conveying a mold into an injection position using the conveying apparatus;
• injecting resin into the mold;
• conveying the mold from the injection position using the conveying apparatus;
• and
• removing a molded product from the mold,
• wherein the first rotating body and the second body support the mold as it is conveyed, and
• wherein the length of the second rotating body in the axial direction is longer than the length of the first rotating body in the axial direction.
