Description
Technical field
This utility model relates to nozzle, the nozzle of a kind of conveniently adjusted flow.
Background technology
Die casting is a big class in mould.In recent years, along with China's automobile, the developing rapidly of motorcycle industry, Die Casting Industry has welcome the new period of development, but meanwhile, also has higher requirement comprehensive mechanical property, life-span and the mould structure etc. of die casting.
In press casting procedure, in order to strengthen the demolding performace of mould, spraying is a most crucial link, it can effectively avoid die casting and compression mod seam, the part making compression mod easy to wear at high temperature has greasy property, reduce die casting frictional resistance when ejecting, prevent sticking to mould, and play cooling effect and avoid compression mod to be too heated.
In the paint finishing of die casting, nozzle is highly important parts, coating is mainly sprayed on mould by the effect of nozzle uniformly and effectively, the most state-of-the-art nozzle is the nozzle that Wal woods company of Germany produces at present, this nozzle and paint valve are designed as one, volume is bigger, the long and narrow complications of dope circuit, coating regulation is by outside hexagon socket head cap screw regulation, coating directly sprays to mould from nozzle after mixing in nozzle chambers with compressed air, therefore there is problem below in the nozzle of this structure: 1, nozzle and paint valve Integral design, volume is excessive, therefore nozzle can only carry out inclined-plane spraying, die cavity inner nozzle penetrates face can produce spraying blind area, die cavity integral surface can not be preferably made to form equal film owing to mould structure limits, the demoulding thus can be caused bad or die surface foot area temperature is higher, affect the demoulding.2, owing to coating regulation is by outside hexagon socket head cap screw regulation, therefore the regulation of nozzle flow is inconvenient.3, directly spray to mould from nozzle after coating mixes in nozzle chambers with compressed air, therefore effective negative pressure can not be formed at coating material passage, injection dynamics and nozzle atomization covering of the fan are not enough, and ejection liquid atomization particle is uneven, and coating material passage is little easily causes spray nozzle clogging in structure design simultaneously.
