ABSTRACT:
An apparatus for evenly distributing forces around a die mounted to an extruder barrel includes a barrel flange mounted around the extruder barrel, the barrel flange providing a flange sealing face and a first angular cam surface, and a die adapter for carrying the die, the die adapter providing an adapter sealing face that opposes the flange sealing face, and a second angular cam surface. The apparatus further includes a pair of opposed clamshells each with a semi-circle opening and a lock channel facing each other, each lock channel having angled cam surfaces facing the first and second angular cam surfaces. A locking mechanism is provided at one end of each pair of opposed clamshells, and a spring-biased link mechanism at the other end of each pair of opposed clamshells, whereby the locking mechanism applies a closure force to at least engage the angled cam surfaces against first and second angular cam surfaces, and the spring-biased link mechanism permits the cam surfaces to bring the sealing faces into sealing contact. The apparatus also provides a counterbalanced spring to bias the lower clamshell.
