Title:
NON-SCREW PLATE TYPE ROTARY PLASTIC INJECTION METHOD AND APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/003670
Kind Code:
A1
Abstract:
Disclosed are a non-screw plate type rotary plastic injection method and the apparatus thereof. A piston which is arranged in circular groove of a round plate and rotatable about center of the plate is used to complete the processes of plastic feeding, injection and pressure holding. The plate type rotary injection apparatus consists of a plate type storage cavity (4) having a circular groove on its round plate, an injection piston (1) rotatable about the plate type storage cavity (4), a support shaft (3), a nozzle (5) and so on. To complete the process of filling plastic materials, the plastic melt enters the plate type storage cavity (4) propelling the injection piston rotates and enlarges the storage cavity. An external force is applied to drive the injection piston (1) to rotate reversely, so as to eject the material in the plate type storage cavity out through the nozzle (5) and into the mould cavity. The torque of the injection piston (1) is maintained, so that the pressure in the mould cavity is maintained and the material shrinkage is compensated. The injection apparatus is featured in its small scale, accurate measurement of material to be stored, low energy consumption of injection and low inertia in injection movement.
