Abstract
A method including a first step of performing clamping of a mold, injection and dwelling in an injection molding machine, a second step of performing a conveyance and a cooling of the mold outside of the machine, and a third step of performing a conveyance of the mold into the machine, an opening of the mold and an ejection of a molded part in the machine. The second step is performed for a first mold, the third step and the next first step are performed for a second mold. The first mold is conveyed by a first conveyance apparatus which is arranged on one lateral side of the machine. The second mold is conveyed by a second conveyance apparatus which is arranged on the other lateral side and is independently driven from the first conveyance apparatus.
Claims19
An injection molding system comprising:
- an injection molding machine which includes one injection nozzle for injecting a material into a first mold and alternately into a second mold on a molding operation position of the injection molding machine, wherein the first mold includes a first pair of molds and the second mold includes a second pair of molds;
- the injection molding machine further including one mechanism for opening and closing the first pair of molds of the first mold and the second pair of molds of the second mold on the molding operation position of the injection molding machine alternately;
- a first conveying machine configured to convey the first mold with a first molded part held between the first pair of molds on the molding operation position out of the molding operation position and to convey the first mold with the first molded part on the first conveying machine onto the molding operation position of the injection molding machine;
- and
- a second conveying machine configured to convey the second mold with a second molded part held between the second pair of molds out of the molding operation position and to convey the second mold with the second molded part on the second conveying machine onto the molding operation position of the injection molding machine,
- wherein the injection molding machine is configured to eject the first molded part from the first mold on the molding operation position and to eject the second molded part from the second mold on the molding operation position,
- wherein the first mold includes a first self-closing unit to close the first pair of molds and the second mold includes a second self-closing unit to close the second pair of molds,
- wherein the first conveying machine is configured to convey the first mold with the first self-closing unit on the molding operation position out of the molding operation position and to convey the first mold with the first self-closing unit on the first conveying machine onto the molding operation position of the injection molding machine, and
- wherein the second conveying machine is configured to convey the second mold with the second self-closing unit on the molding operation position out of the molding operation position and to convey the second mold with the second self-closing unit on the second conveying machine onto the molding operation position of the injection molding machine.
