3. Chinese patent: built-in anti-pull-type mold pushing mechanism of injection machine and moving platen thereof, application number: CN03247922, the applying date: 2003.07.02, publication number: CN2663124, open day: 2004.12.15, applicant: Hengsheng Machines (Shenzhen) Co., Ltd., address: Songgang Town, Baoan District, Shenzhen City, Guangdong Province Tan Tou village Hang Seng industry city, inventor: Wu Weisheng; Yi Hengguang; Feng Liangwei; Pan Zuomei, summary: this utility model provides a kind of injection machine built-in anti-pull-type mold pushing mechanism, comprises ejecting oil cylinder, moving platen, ejects oil cylinder and directly is connected with moving platen; A kind of moving platen that is applied to above-mentioned built-in anti-pull-type mold pushing mechanism does not need by pull bar directly and ejects oil cylinder and be connected.This built-in anti-pull-type mold pushing mechanism is rational in infrastructure, can strengthen the intensity of moving platen, makes that moving platen is stressed evenly, distortion is little, can not produce the phenomenon of die cavity flash at injection moulding process, can prolong the service life of mould; Also have the long advantage of ejection stroke, can conveniently process the product of growing (height), applicability is good; This utility model is simple in structure, is easy to processing, assembling, and applicable to various injection moulding machines, range of application is wider, good market prospect.
Yet, the inventor finds after deliberation with after the market survey, still there are the following problems for above patent: after such injection machine uses a period of time, because the wearing and tearing of oil cylinder and solid plate and moving platen, the operating position of matched moulds and clamping mechanism is not too accurate, has caused matched moulds careless mistake (not in place or mistake position); The tight or tension of locked mode that is to say, after support produces the torsion distortion, can make the pipe that shoots material produce a little shift phenomenon corresponding to the ejaculation position of module, and allowing shoots material produces dislocation, to making unstable product quality.At this situation, there is the people to have designed some cable-stayed horizontal injection molding machines again, it has overcome above shortcoming and has obtained users and favor.But; the inventor finds again; because such injection machine injection pressure is big; produce immense pressure in the injection moment die cavity; if clamp force deficiency; product will cause overlap; thereby influence the quality of product; this mechanism's many places rigidity is hinged; on in use often occurring; the wearing and tearing of lower link are inconsistent; thereby make; following locked mode imbalance; cause taking place in the mold-closing injection mould that expands at last; directly influenced the qualification rate of plastic products, in addition, because its matched moulds and clamping mechanism great majority are manual crank throw matched moulds clamping mechanism; this mechanism's heaviness; die sinking; matched moulds is quite required great effort, and clamp force is produced by the crank throw force-increasing mechanism fully, and finishing locked mode, to move needed strength very big; working strength of workers is big; efficient is low, the production cost height, and; during die sinking; because the existence of clamp force, crank throw are from the moment that straight configuration is done contractile motion, the release of crank throw force-increasing mechanism produces reaction force resets the quick rotation of handle; the workman must hold up tight handle die sinking; the handling safety performance is poor, when serious, has also caused the personal safety accident.So people press for a kind of energy-conservation, efficient, safe injection machine product, make life safer, reliable.
Summary of the invention
The purpose of this utility model provides a kind of energy and solves above-mentioned deficiency, cable-stayed horizontal injection molding machine simple in structure, that clamp force is big, efficient is high, production cost is low, security performance is good.
This cable-stayed horizontal injection molding machine, comprise lathe bed, screw mandrel, barrel, hopper, injection oil cylinder, linkage, clamping and clamping mechanism, described lathe bed top is equipped with hopper, left end is provided with the injection oil cylinder, one end of barrel is connected with the injection oil cylinder, the other end and template are fixed, linkage and clamping mechanism are hinged, clamping is installed on the right-hand member of lathe bed, be characterized in: on linkage, be connected with die cylinder, be hinged with the locking piston dish on clamping mechanism, described die sinking, matched moulds adopt cant to draw crank throw formula oil cylinder mechanism; Described locked mode adopts the disc type oil cylinder mechanism.It adopts the less oil cylinder cant of cylinder diameter to draw crank throw to realize quick die sinking, matched moulds; Adopt the bigger oil cylinder locked mode of cylinder diameter to obtain huge clamp force.
Above-described clamping comprises solid plate, screw mandrel, moving platen, die cylinder, die cylinder bearing and stopping means, and solid plate is connected by screw mandrel with moving platen, and die cylinder is fixed on the die cylinder bearing, and stopping means is installed on the lathe bed.
Above-described linkage comprises long connecting rod, short connecting rod and yoke; a long connecting rod and short connecting rod end and the common hinged composition linkage of yoke wherein; the other end and the moving platen of long connecting rod are hinged; the other end and the clamping mechanism of short connecting rod are hinged, and the other end and the die cylinder of yoke are hinged.
Above-described clamping mechanism comprises locking piston dish and crank throw seat, and the locking piston dish is connected with the crank throw seat, because locked mode dish cylinder diameter is bigger, has strengthened clamp force, has improved the injection moulding area.
Compare with prior art, the beneficial effect of cable-stayed horizontal injection molding machine of the present utility model is:
1. low cost of manufacture, the automaticity height.The utility model changes manual handle reverse die sinking, clamping system into and adopts the less oil cylinder cant of cylinder diameter to draw crank throw to realize quick die sinking, matched moulds, the hydraulic jack that adopts less cylinder diameter is the middle part of push-and-pull crank throw that big short connecting rod is formed obliquely, crank throw is done stretch, contractile motion, thereby driving moving platen moves reciprocatingly on screw mandrel, realize matched moulds, die sinking, alleviated operator's labour intensity greatly, accelerate opening and closing mould speed, improve production efficiency, reduced energy consumption.
2. strengthen clamp force, improved the injection moulding area.The utilization that combines of die cylinder and locked mode dish: die sinking, matched moulds stage locked mode dish are does not have the external force state that is subjected to, and the required power of opening and closing mould is very little, uses less die cylinder can realize quick opening and closing mould, and it is little dynamically to wear and tear, and runnability is good; The locked mode dish work of locked mode stage because locked mode dish cylinder diameter is bigger, produces huge clamp force and can improve the injection moulding area, has fundamentally solved manual crank throw force-increasing mechanism clamp force defect of insufficient.
3. safe and reliable, wide adaptability.Because the utility model adopts the bigger oil cylinder locked mode of cylinder diameter to obtain huge clamp force, the mechanical locked mode that replaces manual crank throw force-increasing mechanism with the locked mode dish hydraulic pressure locked mode of big cylinder diameter, this equipment can reduce by an operator post, because of locked mode pressure is kept by the locked mode dish, safe and reliable, the workman is simple to operate, wide adaptability.
