Abstract:
A blow molding machine comprising:an extruding device configured to extrude a parison; first and second mold-clamping devices configured to clamp first and second pairs of mold halves, respectively, and positioned in a first linear direction, said first and second mold-clamping devices including actuators each positioned in an outer end portion of a respective one of said first and second mold-clamping devices in the first linear direction and being configured to open and close said first and second pairs of mold halves symmetrical to each other in the first linear direction by a respective one of the actuators, the first and second mold-clamping devices being configured to move the first and second pairs of mold halves, respectively, in a second linear direction perpendicular to the first linear direction such that the first and second pairs of mold halves are positioned below extrubing extruding device; a single main base plate configured to reciprocate in the first linear direction to alternately align the first and second pairs of mold halves with said extruding device in said second linear direction such that the first and second mold-clamping devices move and position the first and second pairs of mold halves below the extruding device, respectively; and first and second hammering devices configured to hammer blow pins into said first and second pairs of mold halves, respectively.
