Description
Technical field
The present invention relates to mold closing mechanism technical field, relate to a kind of die cylinder structure of the full hydraulic for injection machine, extruder, die casting machine, hydraulic press etc.
Background technology
The clamping of injection machine, extruder, die casting machine, hydraulic press etc. conventionally adopts hydraulic jack to drive and realizes.The basic demand of the clamping of these full hydraulics is to realize quick low voltage shifting formwork and high-voltage lock mould at a slow speed.The course of work is: mould shifting oil cylinder drives moving platen to move to solid plate, realizes mould matched moulds; Mode-locking oil cylinder drives moving platen to realize high-voltage lock mould; Mold filling is cooling complete after, Mode-locking oil cylinder pressure release, mould shifting oil cylinder drives moving platen to realize die sinking.
Can realize shifting formwork (being die sinking and matched moulds) and locked mode (mold-locked that is about to close) action by two kinds of patterns.A kind of pattern is that shifting formwork and locked mode complete by same oil cylinder, and its shifting formwork is acted on piston and realized and driving by hydraulic oil, and locked mode is by having boosted to hydraulic oil.This clamping structure is very simple; but do not meet the kinetic characteristic of clamping, be difficult to realize quick low voltage shifting formwork and the requirement of high-voltage lock mould at a slow speed, and power consumption is large, precision is low; can be used on closure tonnage is little, speed is not high small-sized machine seldom application at present.
Another kind of pattern is that shifting formwork and locked mode are separated and carried out.Because the required oil pressure of shifting formwork is little, locked mode needs high pressure to carry out, and therefore little mould shifting oil cylinder is set is responsible for shifting formwork, large Mode-locking oil cylinder is set and is responsible for locked mode.The clamping of this pattern has that closing precision is high, template stress equalization, do not need the advantages such as mode transfer, mould-closing stroke be long.On middle-size and small-size machine, conventionally shifting formwork and Mode-locking oil cylinder are set together, on medium-and-large-sized machine, shifting formwork and Mode-locking oil cylinder are divided and be arranged.But the clamping of this form let out in easily cause pressure rising time long, speed slowly, many shortcomings such as even leakage of oil, energy consumption be high, easily cause hydraulic stamping, hydraulic system is complicated, cost is high, large tank processing difficulties.At present, day by day two plate direct press type injection moulding machines of maturation adopt the pattern of two little mould shifting oil cylinders and four large Mode-locking oil cylinders conventionally.But also there is above-mentioned shortcoming.
