It states main 10 one end of nozzle and connects the mainstream incoming interface 211, main 10 other end of nozzle connects the needle-valve single injector 11.
It is also equipped with opening and closing element on main nozzle 10 in the utility model, for controlling between main nozzle 10 and main flow distribution plate 21
ON/OFF.Be also equipped with opening and closing element on needle-valve single injector 11, for control opening between needle-valve single injector 11 and main nozzle 10/
It closes, cylinder 40 is used to control the reciprocating motion of the needle-valve of needle-valve single injector 11, so as to realize the closing of itself and main nozzle 10
And opening.
The cylinder 40 and main nozzle 10 for controlling main nozzle 10 are located at the two sides of main flow distribution plate 21, to there is sufficient sky
Between arrange the cylinder 40, the bigger cylinder 40 of cylinder diameter can be set, the strength of closing is big, can effectively close main nozzle
10, it prevents plastic cement to be cast, leaks out plastic cement.
Molten state plastic cement fluid enters in main nozzle 10 from needle-valve single injector 11, then injects fluid by main nozzle 10 and lead
In flow distribution plate 21.Main flow distribution plate 21 leads the distribution of plastic cement fluid by divided fluid stream to each branch flow distribution plate 22, then by each hot mouth 30
Stream enters various chamber, is subsequently filled product type chamber, after melt plastic cement is cooling, forms product final shape, and finally die sinking ejection takes
Product out.Main nozzle 10 and all hot mouths 30 all use needle valve, can conveniently adjust and fill balance.
It should be noted that there is cylinder 40 set on needle-valve single injector 11 bigger needle-valve to seal power, needle-valve
Single injector 11 is connect with injection molding machine, and when injection molding machine nozzle is not injected, cylinder 40 drives needle-valve that can close needle-valve single injector 11
It closes, prevents the high pressure melten gel in runner plate from flowing out, cause curtain coating phenomenon.It is cast waste material without manual cleaning, advantageous realize is folded
The injection molding full-automatic production of laminar.
The a cast runner structure 100 further includes the temperature for the cooling fluid for flowing through it and is arranged in the master
Cooling structure part 12 between nozzle 10 and the needle-valve single injector 11.
It is equipped with cooling water channel in the cooling structure part 12, when the fluid is flowing that shear rate is big for plastic cement, and fluid, which flows through, to be poured
Since violent frictional heat generation, fluid temperature (F.T.) increase when mouth, plastic cement fluid can be put aside a large amount of when entering flow distribution plate by hot mouth 30
Heat.The water route being arranged in cooling structure part 12 can take away the heat of savings, the flowing of advantageous plastic cement, prevent overheat and
Occur to burn glue phenomenon, to influence product quality.
Please refer to Fig. 4, a cast runner structure 100 further includes that the plate face and use of the branch flow distribution plate 22 is arranged in
In the heating tube for heating the branch flow distribution plate 22 and for detecting the temperature sensor (not shown) for shunting plate temperature, respectively
