Mold device in a molding machine

A mold device, comprising:

• a fixed mold mounted on a retainer plate;
• a movable mold mounted on a movable retainer plate, wherein said movable retainer plate is moved by a clamping cylinder, said movable mold being movable with respect to said fixed mold;
• a revolutionary block including a rotary shaft, wherein said fixed mold is mounted on said revolutionary block, and said revolutionary block is supported revolvably and pivotally with respect to a block supporting plate, said block supporting plate being detachably secured onto said retainer plate for said fixed mold;
• and
• revolutionary and pivotal means for causing said revolutionary block to be revolved and pivoted during an opening and closing operation of said movable mold, said revolutionary and pivotal means including:
• (a) an operating rod including a root side portion received by said movable retainer plate,
• (b) a rack formed on a head portion of said operating rod,
• (c) a plane portion formed on a portion of said operating rod adjacent said head portion, and
• (d) a pinion on one end of said rotary shaft of said revolutionary block adapted to mesh with said rack and contact said plane portion.

• a movable mold mounted on a movable retainer plate, wherein said movable retainer plate is moved by a clamping cylinder, said movable mold being movable with respect to said fixed mold;
• a revolutionary block including a rotary shaft, wherein said movable mold is mounted on said revolutionary block, and said revolutionary block is supported revolvably and pivotally with respect to a block supporting plate, said block supporting plate being detachably secured onto said movable retainer plate;
• and
• revolutionary and pivotal means for causing said revolutionary block to be revolved and pivoted during an opening and closing operation of said movable mold, said revolutionary and pivotal means including:
• (a) an operating rod including a root side portion received by a fixed member with respect to ground,
• (b) a follower cylinder fixedly secured to a fixed member with respect to ground,
• (c) a piston formed on the operating rod and slidably inserted into said follower cylinder to allow movement of said operating rod, and
• (d) a revolutionary arm connected between said operating rod and said revolutionary block.
