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.

Description

technical field [0001] The invention relates to a plastic injection molding method and its equipment, in particular to a screwless plastic disc rotary injection method and device. Background technique [0002] Plastic injection molding machine is the main processing equipment for plastic molding. The injection molding process includes plasticization, material storage, injection filling, pressure holding, cooling, mold opening and ejection, among which the processes of material storage, injection filling, and pressure holding are completed in the injection device. In the traditional plunger type injection device or screw one-line injection device, the material (plastic melt) continuously enters the front end of the storage barrel during material storage, and pushes the plunger or screw back in a straight line, and the storage volume increases to complete the storage. ;During injection, the plunger or screw moves forward in a straight line under the drive of external force, p...
