Method and apparatus for batched compression molding of rubber and plastic products

A device for batched compression molding of rubber and plastic products by means of multiple mold cavities, comprising:

• a cable transmission mechanism comprising two partial gear sets, a mold-moving rotary winding wheel, a mold-moving cable, a blank-conveying rotary winding wheel, and a blank-conveying cable, wherein the two partial gear sets comprise a mold-moving partial gear set and a blank-conveying partial gear set;
• a three-bar linkage mechanism;
• a bottle cap mold comprising a male mold and a female mold;
• a blank shuttle;
• and
• a male mold supporting plate;
• wherein a plurality of male molds are evenly distributed on a periphery of the male mold supporting plate, one female mold being arranged under each of the plurality of male molds, with one blank shuttle arranged between the male mold and the female mold of each pair,
• the mold-moving partial gear set and the mold-moving rotary winding wheel are connected,
• the blank-conveying partial gear set and the blank-conveying rotary winding wheel are connected,
• one end of the mold-moving cable is wound on the mold-moving rotary winding wheel, and another end of the mold-moving cable is connected with the male mold supporting plate,
• one end of the blank-conveying cable is wound on the blank-conveying rotary winding wheel, and another end of the blank-conveying cable is fixedly connected to a blank-conveying cable holder, and
• a plurality of three-bar linkage mechanisms are distributed on the blank-conveying cable holder, wherein one end of each of the plurality of three-bar linkage mechanisms is connected with the blank-conveying cable holder, and another end of each of the plurality of three-bar linkage mechanisms is correspondingly connected with one blank shuttle.
