Container manufacturing apparatus

A container manufacturing device comprising:

• a container molding module configured to inject air to a pre-form;
• wherein the container molding module comprises:
• a plurality of separable container molds comprising a cavity with the pre-form of the container accommodated therein and corresponding to an external shape of the container and configured to be spaced apart from each other or to contact each other;
• a plurality of moving blocks attached to the container mold to move the container mold;
• a driving drive configured to provide driving force for moving the moving block;
• a driving force train portion configured to connect the driving drive and the moving block to transmit power of the driving drive to the moving block;
• a fix bar arranged through the plurality of moving blocks when the plurality of container molds are attached to each other;
• and
• a stumbling device coupled to the fix bar to maintain a state in which the plurality of container molds are attached to each other when the plurality of container molds are attached to each other,
• wherein each container mold comprises a first container mold and a second container mold;
• wherein each moving block comprises a first moving block coupled to a rear portion of the first container mold and a second moving block coupled to a rear portion of the second container mold;
• wherein the driving force train portion comprises a pivot portion arranged on a rotor shaft of the driving drive, first and second coupling links that are pivotably provided at opposite ends of the pivot portion, and first and second coupling plates connected to the first and second coupling links and the first and second moving blocks, respectively;
• and
• wherein the first and second coupling links are attached to each other when the first and second coupling links approach the pivot portion due to rotation of the pivot portion, and first and second container molds are separated from each other when the first and second coupling links are spread out of the pivot portion.
