Abstract:
An apparatus comprising:a first mold comprising a first upper mold and a first lower mold, the first mold having an opening/closing direction, a second mold comprising a second upper mold and a second lower mold, the second mold having an opening/closing direction, a third mold comprising a third upper mold and a third lower mold, the third mold having an opening/closing direction a first moving means, a second moving means, wherein the first and second molds are disposed such that their respective opening/closing directions are aligned and the first and second lower molds are arranged and constructed to move or slide transversely with respect to the first and second upper molds from the opening/closing positions, and wherein the first moving means is arranged and constructed to move the first and second lower molds transversely with respect to the first and second upper molds such that transverse movement distances of the first and second lower molds are different from each other, wherein the first, second and third molds are disposed such that their respective opening/closing directions are aligned and the third lower mold is arranged and constructed to move transversely with respect to the third upper mold from the opening/closing direction of the third mold, and wherein the second moving means is arranged and constructed to move the third lower mold transversely with respect to the third upper mold such that transverse movement distance of the third lower mold is different from the transverse movement distances of the first and second lower molds, and wherein the first moving means comprises a first air cylinder having a first air cylinder rod aligned transversely to the opening/closing direction of the first and second molds, the first air cylinder rod being linked to the first and second lower molds, so as to transversely move the first and second lower molds when the first and second molds are in the mold open positions, and wherein the second moving means comprises a second air cylinder having a second air cylinder rod aligned transversely to the opening/closing direction of the third mold, the second air cylinder rod being linked to the third lower mold, so as to transversely move the third lower mold when the third mold is in the mold open position.
