Abstract

The invention provides a kind of ultra-large plastic injecting and forming process and device, the device includes plastic injecting, performing mechanism; clamping mechanism; hydraulic system; electric appliance control system, there sets a safe door on the machine mantle; the modelocker unit assembly has series oil cylinder, several grades reinforcement structure; the die thickness can adjust device unit assembly; brake safe device unit assembly. The process is: automatic starting, clamping pressure, locked mode, injecting, premolding, injection completing, locking mode locked force is released, material quantity system, safe door, die sinking, mold loose core, taking the combinations, mold loose core reset. The mold thickness adjusting device unit assembly can change large mold with variable specs. The teeth braking safe device unit assembly can guarantee the safely operation.

Description

technical field [0001] The present invention relates to plastic injection molding process and equipment, in particular to ultra-large plastic injection molding process and equipment Background technique [0002] At present, injection molding machines at home and abroad are basically in one mode-horizontal models, single-point injection. Injection volume 38000cm 3 The above-mentioned large injection molding machines are still simply enlarged from small injection molding machines. The injection volume is 38000cm 3 The large injection molding machine is heavy, weighing up to 200 tons; the machine consumes a lot of energy, with an installed power of 460kw; the machine is expensive; single-point injection cannot process recycled waste plastics with poor fluidity and other defects. If the horizontal, single-shot injection molding machine continues to increase the injection volume, the machine will be too heavy to be transported and installed. Super-large injection molding pass...
