Mixing head |
| abstract |
A high pressure mixing head is disclosed for combining a plurality of reactive fluid polymeric components to form a mixture thereof for molding purposes. The mixing head incorporates an expulsion piston operating in a mixing chamber into which the several components are individually admitted through separate inlet openings which are covered and uncovered by reciprocation of the expulsion piston. This piston is actuated by connection to a power piston operating in a power cylinder, and means such as a limit switch assembly is mounted on the power cylinder to detect the position of the power piston and hence the expulsion piston in the mixing chamber. This switch is used to control the "shot time" of the mixing head cycle of operation; that is, the time during which the inlet ports to the mixing chamber remain uncovered by the expulsion plunger to allow the components to enter the mixing chamber through the respective inlet ports. This arrangement affords more accurate control of the shot time than has been provided in similar apparatus heretofore. |
