Description
Technical field
The present invention relates to injection machine field, specifically a kind of folding mould of the self-locking clamping for being based on two triggers
Method.
Background technology
The mould-matching structure of existing two-plate injection machine, mainly there is two kinds of hydraulic direct locking-type and combined type.Wherein, hydraulic direct locking
Formula workflow is mainly：Moved by rapid mould-moving oil cylinder pushing moving platen first, then by band-type brake structure by Draw bar lock
Extremely, then by Mode-locking oil cylinder by mold-locked, the hydraulic direct locking-type has an automatic mold-adjustment function, but the hydraulic pressure system required for it
System is relative complex, and reliability is poor, and the size that takes up room compares three-plate type injection machine also no particularly apparent advantage, especially
For clamp force, it is necessary to four very big oil cylinders when larger, power is big, and during locked mode and pressurize is the energy for needing consumption larger
Amount.Typical combined type, then mainly drive moving platen quickly to move by being fixed on Quick cylinder in quiet template, and mould is closed
Close, specifically, between moving platen and pull bar be relatively fixed by positioning and locking device, pull bar is then pulled by Mode-locking oil cylinder
By mold-locked.In combined type, mode transfer structure is generally divided into following two：First, fine adjustment pull bar is passed through in Mode-locking oil cylinder
Position, makes pull bar tooth top agree with, position and then lock pull bar with the root position for entering lock nut；2nd, by engines such as motors
Structure is adjusted into lock nut location, pull bar agreed with, position and then lock pull bar with the position for entering lock nut.Both mode transfer structures
In, four pull bars or enter lock nut and be required for increasing single power set, while oil piping system complicates, increased quite big
Cost, be poorly suitable for middle-size and small-size two-plate injection machine.
Patent (notification number：CN201313365Y) disclose a kind of clamping apparatus of two triggers, including moving platen, pull bar,
Solid plate, pull-rod nut, pull bar pressing plate, mould shifting oil cylinder, band-type brake oil cylinder, two halves formula folding band-type brake nut, band-type brake locating shaft, band-type brake
