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.
Claims25
A method of manufacturing a molded part by one injection molding machine, the method comprising:
- a first step of clamping a mold, injecting a material into the mold, and dwelling the mold in the injection molding machine;
- a second step of conveying the mold outside of the injection molding machine and cooling the mold outside of the injection molding machine, the second step being performed after the first step;
- and
- a third step of conveying the mold into the injection molding machine, opening the mold and ejecting a molded part in the injection molding machine, the third step being performed after the second step,
- wherein the first to third steps for a first mold for a first molded part and the first to third steps for a second mold for a second molded part are repeated multiple times,
- wherein the third step and the next first step for the second mold are performed after starting conveying the first mold outside of the injection molding machine in the second step for the first mold,
- wherein the third step and the next first step for the first mold are performed after starting conveying the second mold outside of the injection molding machine in the second step for the second mold,
- wherein the first mold is conveyed by a first conveyance apparatus arranged on one lateral side of the injection molding machine,
- wherein the second mold is conveyed by a second conveyance apparatus arranged on the other lateral side of the injection molding machine, the second conveyance apparatus being driven independently from the first conveyance apparatus,
- wherein, in the second step for the first mold, the second conveyance apparatus starts to convey the second mold in the third step for the second mold after the first conveyance apparatus starts to convey the first mold,
- wherein, in the third step for the first mold, the first mold including the first molded part is conveyed in a horizontal orientation into the injection molding machine by the first conveyance apparatus, and
- wherein, in the third step for the second mold, the second mold including the second molded part is conveyed in the horizontal orientation into the injection molding machine by the second conveyance apparatus.
