Abstract
A two-plate die closing apparatus with booststrap die-locking mechanism for the injection moulding machine of plastics is composed of driver unit, movable and fixed die plates, front and back connecting-rod sets, guide posts, backpressure axle sleeves, slide sleeve group, guide column, and push arm.
Description
Technical field
A kind of two-plate mold closing mechanism that possesses the bootstrapping clamping mechanism is especially for the mold closing mechanism of injection machine in the plastics machinery industry.
Background technology
The traditional injection moulding machine is in order to overcome pressure powerful in injection process, and mold closing mechanism is three plate structures.In this clamping; the machining tolerance of axle, pin and the connecting rod of connection rear pattern plates such as toggle mechanism and moving die plate and between them factor such as fit clearance can moving die plate and fixed form matched moulds state be produced a very large impact; the matched moulds excesssive gap can cause workpiece burr to occur, and the interference of matched moulds gap easily causes mould or device damage.For overcoming above deficiency, the machining accuracy of the correlated parts of having to greatly improve, and realize that with the version of complexity matched moulds and locked mode and release and die sinking move.Has numerous and diverse huge, the shortcoming such as difficulty of processing is high, production cost is high, closing precision is low of structure.
Between this, the injection machine of some two-plate clampings has appearred in succession.In international application CH96/00344 disclosed " closing unit of injection machine " patent application, closing unit has the supporting guide that fixedly installs, on this supporting guide, be provided with fixing clamping plate and the clamping plate that can on supporting guide, move, rear at these two clamping plate is respectively equipped with gantry post, and a matched moulds drive unit is hinged in the gantry post.But be suspended between two gantry posts to this matched moulds drive unit freely-movable.Though the huge clamping pressure of this structure can not act on the supporting guide; but because leverage; hinge point at the matched moulds drive unit can produce the distortion power that is higher than injection pressure, and the clamping of this structure only can be useful in the miniature and small injecting machine.And in Chinese patent 03114077.7 disclosed " two plate mould-locking structure injection machines and manufacture method thereof " patent application, by quick oil cylinder is set between moving die plate and fixed form, at pull bar one end Mode-locking oil cylinder is set, realize shifting formwork with quick oil cylinder, Mode-locking oil cylinder is used for overcoming the immense pressure that injection process produces.This mold closing mechanism needs two group oil cylinders to work respectively, and the equipment operation energy consumption of making significantly improves, and the oil in the oil cylinder work leaks and is difficult to avoid, and this working method is unfavorable for improving the matched moulds operating efficiency.There is the production cost height of injecting products, easily pollutes shortcomings such as working environment and inefficiency.
Summary of the invention
At the deficiencies in the prior art, the present invention proposes the two-plate mold closing mechanism of the pressure bootstrapping locking moving die plate that produces when a kind of injection machine can utilize injection moulding.
The problem to be solved in the present invention realizes by following measure: this mold closing mechanism comprises fixed form, moving die plate, drive unit etc.And have paired connection rod set, lead, back-pressure axle sleeve, slip cap group, guide pillar and a pusher arm.Moving die plate and front rod group one end are rotationally connected by pivot, and back-pressure axle sleeve and back link group one end are rotationally connected by pivot, and the front rod group and the back link group other end are rotationally connected by pivot and slip cap.Axial and the lead of all pivots of connection connection rod set is axially axially vertical respectively with guide pillar, and lead is axial, and axially also maintenance is vertical mutually with guide pillar.The pivot that connects front rod group and moving die plate, and the pivot that connects back link group and back-pressure axle sleeve, can by lead radially vertical symmetry arrange, also can be by lead radial parallel symmetry arrangement.Guide pillar is pressed the matched moulds plane of axially parallel in fixed form and moving die plate, is fixedly connected on the pusher arm, and slip cap and guide pillar are slidingly installed.Lead is by the matched moulds Plane Installation that is axially perpendicular to fixed form and moving die plate, lead can be fixedlyed connected with fixed form by securing member, moving die plate is slidingly installed on the axis of guide with respect to fixed form by axle sleeve, the back-pressure axle sleeve is close to moving die plate and lead is slidingly installed, lead also can be fixedly connected on the moving die plate by securing member, and the back-pressure axle sleeve is close to moving die plate and lead is slidingly installed.The back-pressure axle sleeve is only limit at lead and axially is forced to slide, and slip cap is only limit at guide pillar and axially is forced to slide.Drive unit should have power output and moment keeps function, and its power arm is connected with pusher arm by jockey.
The present invention compared with prior art has the following advantages:
1, drive unit provides moving die plate opening and closing movement and a clamp force, provide secondary bootstrapping clamp force by the immense pressure that produces in the injection moulding process, injection pressure is big more, and clamp force is also big more, possessed good locked mode effect, can effectively ensure the precision of injecting products.
2, matched moulds and locked mode and release and die sinking action is once finished, matched moulds and opening speed have been improved, opening stroke can be set arbitrarily according to mould and production requirement, production efficiency is improved, and behind a locked mode not in the needs extra power, the equipment operation energy consumption reduces, and helps reducing production cost of products.
3, mold closing mechanism is simple in structure, and requirement on machining accuracy is relatively low, and does not need mould adjusting mechanism and lubricating system, and production cost is greatly reduced.
4, the mold closing mechanism of this structure has been widened the range of application of two-plate injection machine applicable to the injection machine of large, medium and small various models.
