Description
Technical field
The present invention relates to a kind of clamping apparatus of injection molding machine, belong to plastics forming equipment field.
Background technique
Conventional injection molding machine is generally used three plate mould-matching structures, and at present in European and American developed countries, two compact-sized plates
Formula injection molding machine has become the market mainstream.The action process of typical two plates combined-type mold clamping mechanism is as follows: by consolidating with solid plate
Fixed rapid mould-moving oil cylinder driving template fast moves, until mold is closed;At this point, moving template and pull rod are positioned by retaining
Locking device is relatively fixed, then pulls pull rod by mold-locked by Mode-locking oil cylinder again.The characteristics of clamping mechanism is in shifting formwork
Pull rod is fixed in the process, and moving template slides on pull rod;In mode locking, pull rod is relatively fixed with moving template, and pull rod is relative to fixed
Template movement, i.e. movable plate pole, foreboard pressure stabilizing.Two-plate type injection machine reduces one piece of template than three-plate type injection molding machine, can reduce
20% or more main screw lift can save lot of materials and space occupied, low cost, equipment formed precision height.
The clamping apparatus of existing most of two-plate type injection machines is all made of to guarantee locking nut and the accurate obvolvent of pull rod
The mode of secondary fine tuning, it is desirable that the connection type of its four pull rods and template is floating type connection, i.e., when pull rod and template band-type brake
When, four pull rods need just guarantee in the same plane parallel between moving template and solid plate with the position of template band-type brake
Degree meets the requirements, and every pull rod may all shift move by first making every pull rod fine tuning before band-type brake every time
Make to guarantee to reset to confirm band-type brake position again, this requires individually control four adjusting oil cylinders.Patent ZL200820125062.5
The clamping apparatus of the two-plate type injection machine, pull rod are fixed with solid plate, band-type brake part and high-voltage lock mould oil cylinder piston
Connection type is floating type connection, equally needs to finely tune band-type brake part before band-type brake.Micro-adjustable handle rod or band-type brake part require
Very high control technology water product, and band-type brake part is required to have higher machining accuracy, and each trimming movement has also extended
At the time needed for entire band-type brake, machine operation efficiency is influenced.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the shortcomings of in the prior art and provide a kind of mode locking of two triggers
Device, the pull rod of the device and the connection at moving template are the mode being completely fixed, and band-type brake part and high-voltage lock mould part are whole
Design is on the right side of solid plate;It can be by manually adjusting the band-type brake threaded adjustment by four pull rods in same position when putting together machines
It is completely fixed afterwards with moving template, deflection is identical after guaranteeing pull rod stress, and internal contracting brake mechanism is using the right side of solid plate as base
Quasi- face is precisely resetted after die sinking by reset spring every time, and moving template is also that benchmark face is real using the right side of solid plate when molding
It is now accurately positioned, therefore can guarantee very high closing precision.Because of the special designing of internal contracting brake mechanism, molds and embrace by establishing
The uniform reference surface of lock while guaranteeing the accurate reset of band-type brake part, eliminates the control system of fine tuning internal contracting brake mechanism, furthermore
Mode locking is built in the control of mould-closing stroke and presses through the control of journey and requires simpler, to reduce equipment cost, improves and sets
Standby working efficiency, so that machine high-quality performance is more easily implemented.
The present invention solves the technical solution that above-mentioned technical problem is taken are as follows: a kind of clamping apparatus of injection molding machine, including it is dynamic
Template, pull-rod nut, pull rod pressing plate, pull rod, mould shifting oil cylinder, solid plate, two halves formula folding band-type brake nut, band-type brake oil cylinder, limit
Pressing plate, high-voltage lock mould cylinder body, high-voltage lock mould oil cylinder piston, high-voltage lock mould cylinder cover, sliding block, reset spring and preload spiral shell
Pull rod and moving template can be completely fixed by bolt by pull-rod nut and pull rod pressing plate;Moving template is pulled to realize by mould shifting oil cylinder
Rapid mould-moving is simultaneously accurately positioned according to datum level;Two halves formula is driven to open and close band-type brake nut band-type brake or open by control band-type brake oil cylinder
Lock;High-voltage lock mould cylinder body one end is fixed on solid plate by high-voltage lock mould oil end cap;High-voltage lock mould oil cylinder piston covers
In high-voltage lock mould cylinder body and it can be moved forward and backward;Using solid plate right side as benchmark face, forming sliding slot by limit pressing plate will be slided
Block, which is limited in high-voltage lock mould oil end cover surface, move up and down it can, and guarantee four sliding block right ends in the same plane and
It is parallel with datum level;Pretension bolt with reset spring passes through two halves formula and opens and closes band-type brake nut, is made by pre-tightening reset spring
Two halves formula opens and closes band-type brake nut and shoe contact, and guarantees that two halves formula folding band-type brake nut can be moved forward and backward on pretension bolt;
Entire clamping apparatus can be made instantaneously to set up accurate clamp force by high-voltage lock mould cylinder body and high-voltage lock mould oil cylinder piston;It is logical
Clamp force can directly be transmitted in band-type brake by crossing high pressure Mode-locking oil cylinder piston.
Compared with the prior art, the advantages of the present invention are as follows:
1. four two halves formula folding band-type brake nuts can be by reset spring certainly after opening a sluice gate using solid plate right side as benchmark face
It is dynamic reset and with datum level keeping parallelism, realize the precise positioning of band-type brake nut, avoid each because of original floating type connection
The position for individually adjusting each band-type brake nut or every pull rod is required when mode locking, only need to accurately be controlled according to datum level in molding
Template position is braked, so as to shorten the cycle of operation of clamping apparatus.
2. having saved entire mode locking since this device saves four band-type brake nuts or four pull rod fine adjustment control systems
The cost of device.
