Product Description
ACCUMULATING HEAD
Head mode: the accumulating ejection head is designed with material center coming-in type and removing the plastic melting line on the product surface, easily for material or color change, saving the time & material cost with speedy operation.
EXTRUSION SYSTEM
Gradient mixing type with high-speed energy saving design, gradually changed screw with same distance and different deep. Material of screw: High quality nitriding steel 38CrMoAlA,with nitriding surface HV≥800,brittleness≤2. Material of barrel: High quality nitriding steel 38CrMoAlA,with nitriding surface HV≥900,brittleness≤2.
HYDRAULIC SYSTEM
The main hydraulic system is mainly composed of servo motor, gear pump, pressure regulating valve block, reversing valve blocks, cylinders and oil chillers. It controls platens open & close, extrusion system up & down, blow pin actions, or core in and other special actions.
ELECTRICAL CONTROL
The electrical control system is composed of operation panel, temperature control module, PLC, input & output module, proportion board, contactors, voltage stabilized source, air swtiches, mid relays, proximity switches, inverter and motors. The operation panel contains power switch, touch screen, alarm, hot cutter knob, auto cycle button, emergency stop button, action reversion button, extruding speed button.
MECHANICAL STRUCTURE
Clamping unit is composed of front & back platens, clamping unit, mould clamping hydraulic cylinders, synchronizing mechanism, with the structure of nether crank design. Platen movements open & close is assisted with linear guide rails & ball bearing sliders to increase action smoothness and position precision. The end positions & slow speed positions are controlled by travelling electric transducer.
AIR & WATER SUPPLY
The pneumatic system contains air cylinder, air valves, air filters, air tubes, fast plugs and so on, for controlling the actions of head inner blowing, blow pin blowing, auto-deflashing, or pushing in & out for some special moulds. The necessary air pressure is 0.8~1.2 Mpa, air consumption is 1.2~1.6 M3/min. The water system contains water distributing blocks, ball valves, tubes, connectors and so on, for chilling the screw & barrel, hard gear box, blowing units and moulds. The necessary water pressure is 0.2~0.4 Mpa, water consumption is 12.5 m3/hour.
