Container manufacturing apparatus

A container manufacturing device comprising:

• a pre-form molding module configured to form a pre-form of a container using a resin material;
• a container molding module configured to inject air to the pre-form to form the container;
• and
• a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate,
• wherein the container molding module comprises:
• a container mold forming a cavity that accommodates the pre-form and corresponds to an external shape of the container, the container mold includes a first container mold and a second container mold that are configured to be spaced apart from each other or to be coupled to each other;
• a moving block attached to the container mold to move the container mold, the moving block includes 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;
• a driver configured to provide a driving force for moving the moving block;
• a driving force train portion configured to connect the driver and the moving block to transmit the driving force of the driver to the moving block;
• a fix bar arranged through the moving block when the first and second container molds are coupled to each other;
• a latching device coupled to the fix bar to maintain a state in which the first and second container molds are coupled to each other;
• and
• a support block holding the fix bar and located behind the first moving block, the support block being configured to selectively contact the first moving block while moving along with the fixing bar,
• wherein the rib plate is detachably accommodated and supported on the rotary table, and the pre-form molding module is configured to separate and lift only the rib plate from the rotary table to be installed to the pre-form molding module while the rotary table is stationary,
• wherein the driving force train portion comprises a pivot portion arranged on a rotor shaft of the driver, first and second links that are pivotably provided at opposite ends of the pivot portion, and first and second coupling plates connected to the first and second links and the first and second moving blocks, respectively,
• wherein when the pivot portion pulls the first and second links toward the pivot portion to be close to each other by rotating in a first direction, the first and second links are configured to move the first and second container molds toward each other to be coupled to each other, and when the pivot portion pushes the first and second links from the pivot portion to move away from each other by rotating in a second direction that is opposite to the first direction, the first and second links are configured to move the first and second container molds away from each other to be separated from each other,
• wherein the fix bar is provided to the first moving block and extends toward the second moving block, and when the first and second container molds are coupled to each other, the fix bar passes through the second moving block to be exposed outside the second moving block and the latching device is latched on an end portion of the fix bar exposed outside the second moving block,
• wherein when the first and second container molds are coupled to each other, the support block contacts a rear portion of the first moving block, and when the first and second container molds are separated from each other, the support block is separated from the first moving block,
• wherein an air supply member is provided below the container mold, and is configured to supply air into the pre-form accommodated in the cavity and to expand the pre-form to form the container,
• wherein the air supply member comprises:
• an air supply pipe located below the rotary table, the air supply pipe being configured to selectively pass through the rotary table and the rib plate to be inserted into the pre-form held by the rib plate while moving in a vertical direction;
• an air supply device configured to supply air to the air pipe;
• and
• a guide member provided below the rotary table to be moved upward and downward, provided between the rotary table and the air supply pipe to allow the air supply pipe to pass through the guide member and to guide up and down movement of the air supply pipe, and coupled to a bottom surface of the rib plate for supporting the pre-form.
