Abstract
A blow molding mold has first and second fixtures. The first fixture includes drive means, typically in the form of pins, while the second mold fixture has drive receiving means, typically in the form of holes. When the second mold fixture is in registration with the first mold fixture, the drive means are extended to lock and locate the two fixtures together to enable blow molding without a blow molding press. The method of blow molding uses a robotic arm to move a lightweight second mold fixture to accept a parison as it is extruded. After extrusion the arm moves the second fixture toward the first fixture so that the fixtures can be located and locked together. A single robot using a single extrusion head can serve several mold stations depending upon cycle times.
