Compression molding machine and method of compression molding

A compression molding machine, comprising

• a first mold chase;
• a second mold chase opposed to the first mold chase;
• a compression actuation arrangement comprising at least two actuating units for moving the second mold chase towards the first mold chase;
• and
• a base part,
• wherein each of the at least two actuating unit comprises a first inverted wedge member and a second wedge member movable relative to the first inverted wedge member,
• wherein the first mold chase is fixed in a position spaced apart from the base part so as to be suspended above the base part,
• wherein the second mold chase is disposed between the base part and the first mold chase, the second mold chase being movable relative to the base part and the first mold chase along a movement axis, whereby the movement axis extends perpendicularly between the base part and the first mold chase,
• wherein the compression actuation arrangement is disposed between the second mold chase and the base part for moving the second mold chase along the movement axis,
• wherein the at least two actuating units are disposed to independently engage at least two different portions of the second mold chase respectively,
• wherein the first inverted wedge member is movable relative to the base part along an actuation axis parallel to the movement axis of the second mold chase,
• wherein the second wedge member is movable relative to the first inverted wedge member along a transmission axis perpendicular to the movement axis of the second mold chase,
• wherein each actuating unit comprises a drive mechanism coupled to the second wedge member to move the second wedge member along the transmission axis,
• wherein an inclined surface of the first inverted wedge member and an inclined surface of the second wedge member are slidably engaged to each other in a manner so as to convert a motion of the second wedge member along the transmission axis to a motion of the first inverted wedge member along the actuation axis for moving the second mold chase along the movement axis, whereby the compression actuation arrangement is operable to move the second mold chase towards the first mold chase for cooperatively applying a compression force therebetween.
