It is slidably connected by valve needle cover between described needle and hot nozzle body.
Described valve gate is inverted cone-shaped structure, and the bottom of needle is formed with the inverted cone face coordinated with valve gate.
Described piston rod has many, is uniformly distributed circumferentially at hot nozzle outer body between many piston rods.
Described piston rod is vertically slidably connected on cylinder body.
This utility model has the beneficial effects that: this utility model includes hot nozzle main body, needle, hot nozzle sheath, cylinder body, upper piston, lower piston, hot nozzle body interior offers hot runner passage, hot nozzle main body includes master and penetrates nozzle, lower master penetrates nozzle, hot nozzle body, nozzle core, hot runner passage forms valve gate in the bottom of nozzle core, hot nozzle sheath is fixed by socket outside hot nozzle body and nozzle core, cylinder body is fixed by socket outside hot nozzle sheath, two air inlets are offered outside cylinder body, upper piston is vertically slidably connected at lower master and penetrates inside nozzle, it is connected by piston rod between upper piston with lower piston, needle top is fixed on upper piston；When air inlet ventilation downwards, under the drive of air pressure, lower piston moves upward, lower piston drives upper piston and needle to move upwardly together by piston rod simultaneously, now valve gate is in opening, plastic rubber material in hot runner passage flows in die cavity, after cavity filling, lower section air inlet stops air inlet, top air inlet starts air inlet, in like manner the drive lower piston at air pressure moves downward, lower piston drives upper piston and needle to move downwardly together by piston rod simultaneously, and now valve gate is closed, and injection stops；This utility model have employed upper and lower dual-piston structure, connected by piston rod, for traditional single-point needle valve, simplify the internal structure of cylinder body, the processing making the hot nozzle of single-point needle valve becomes the most simple and convenient, directly can process air flue in template simultaneously, eliminate the Teflon pipe connector as air flue, enormously simplify the processor of mould template, and direct snap joint can connect air flue in the installation process of mould, save by the unnecessary trouble brought in Teflon pipe installation process, install more simple and convenient.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that this utility model valve gate is in closure state.
Fig. 2 is the structural representation that this utility model valve gate is in opening.
Detailed description of the invention:
nullBelow in conjunction with the accompanying drawings this utility model is further described，As shown in Figure 1 and 2，The hot nozzle of single-point needle valve that this utility model provides includes hot nozzle main body 6、Needle 1、Hot nozzle sheath 2、Cylinder body 3、Upper piston 4、Lower piston 5，Hot nozzle main body 6 is internal offers the hot runner passage 60 extending respectively to hot nozzle main body 6 top and bottom，Hot nozzle main body 6 includes the most interconnective upper master and penetrates nozzle 61、Lower master penetrates nozzle 62、Hot nozzle body 63、Nozzle core 64，Needle 1 is positioned in hot runner passage 60 and is vertically slidably connected on hot nozzle body 63，Hot runner passage 60 is formed and the valve gate 601 coordinated bottom needle 1 in the bottom of nozzle core 64，When valve gate 601 is in closure state，Just it is plugged in valve gate 601 formation bottom needle 1 and seals fit structure，Hot nozzle sheath 2 is fixed by socket outside hot nozzle body 63 and nozzle core 64，Cylinder body 3 is fixed by socket outside hot nozzle sheath 2，Lower piston 5 is vertically slidably connected in cylinder body 3 inner chamber and cylinder body 3 inner chamber is separated into two chambers，Cylinder body 3 is outside offers two each and air inlets 31 of one of them chamber，Upper piston 4 is vertically slidably connected at lower master and penetrates nozzle 62 inside，It is connected by piston rod 7 between upper piston 4 with lower piston 5，Needle 1 top is fixed on upper piston 4.
It is slidably connected by valve needle cover 8 between needle 1 and hot nozzle body 63 so that needle 1 slides more steadily, more smooth and easy.Valve gate 601 is inverted cone-shaped structure, and the bottom of needle 1 is formed with the inverted cone face 11 coordinated with valve gate 601, it is possible to being automatically directed at location, closure state lower seal effect is more preferable.Piston rod 7 has many, is uniformly distributed circumferentially between many piston rods 7 outside hot nozzle body 63, and piston rod 7 is vertically slidably connected on cylinder body 3 so that upper piston 4 and lower piston 5 slide more steady.
Utility model works principle is: when air inlet 31 is ventilated downwards, under the drive of air pressure, lower piston 5 moves upward, lower piston 5 drives upper piston 4 and needle 1 to move upwardly together by piston rod 7 simultaneously, now valve gate 601 is in opening, plastic rubber material in hot runner passage 60 flows in die cavity, after cavity filling, lower section air inlet 31 stops air inlet, top air inlet 31 starts air inlet, in like manner the drive lower piston 5 at air pressure moves downward, lower piston 5 drives upper piston 4 and needle 1 to move downwardly together by piston rod 7 simultaneously, now valve gate 601 is closed, injection stops；This utility model have employed upper and lower dual-piston structure, connected by piston rod 7, for traditional single-point needle valve, simplify the internal structure of cylinder body 3, the processing making the hot nozzle of single-point needle valve becomes the most simple and convenient, directly can process air flue in template simultaneously, eliminate the Teflon pipe connector as air flue, enormously simplify the processor of mould template, and direct snap joint can connect air flue in the installation process of mould, save by the unnecessary trouble brought in Teflon pipe installation process, install more simple and convenient.
