Abstract
The invention discloses a lever-valve needle single nozzle which comprises a feed nozzle cap and a side cylinder support body, wherein a feed opening is formed in the center of the feed nozzle cap; the side cylinder support body is connected to the lower end of the feed nozzle cap; the feed opening of the side cylinder support body corresponds to the feed passage of the side cylinder support body; a switching-over body is arranged at the lower end of the side cylinder support body; the feed passage is arranged in the middle of the switching-over body longitudinally, and is inclined; heaters are clung to the outer sides of the side cylinder support body and the switching-over body; the upper end of the switching-over body is communicated with the feed passage of the side cylinder support body; the lower end of the switching-over body is communicated with the central hole of a spray nozzle main body. The lever-valve needle single nozzle has the advantages that the structure is simple; the production cost is low; meanwhile, a cylinder body is far away from thermal source of a hot runner, so as to efficiently reduce the overheating phenomenon at the periphery of a seal ring, prolong the service life of the seal ring, and further prolong the service life of the cylinder; moreover, the mobile strength of a valve needle is effectively enhanced through a lever, so that the high injection pressure requirement of production activity is met effectively.
Description
Technical field
The present invention relates to a kind of lever needle list mouth, particularly a kind of Injection Industry lever needle list mouth.
Background technology
Present needle list mouth be all cylinder or oil cylinder and single injector at one, sealing ring easily damages in a hot environment so on the whole, greatly reduce the service life of cylinder.
Summary of the invention
Shortcoming for existing needle list mouth, the invention provides a kind of novel lever needle list mouth.
To achieve these goals, the measure that the present invention takes
A kind of lever needle list mouth, comprise the feed nozzle cap, side cylinder supporter, described feed nozzle Mao De center is provided with charging hole, the lower end of feed nozzle cap is connected with side cylinder supporter, and the charging hole of feed nozzle cap is corresponding with the feeding-passage of side cylinder supporter, the lower end of side cylinder supporter is provided with chovr body, the chovr body central longitudinal is to being provided with feeding-passage, and feeding-passage is skewed, the outside of side cylinder supporter and chovr body is close to and heater, the upper end of chovr body communicates with the feeding-passage of side cylinder supporter, the lower end of chovr body communicates with the centre bore of nozzle body, nozzle body upper end outer race has the nozzle holder, the lower end of nozzle body is connected with the discharging gate cap, nozzle body also is glued with heater outward, be inserted with needle in the centre bore of nozzle body, the tapered bottom end of needle is corresponding with the interior hole shape of discharging gate cap, the top of needle withstands on the recess position of an end of lever, lever is rotatably connected on bracing frame, bracing frame is fixed on side cylinder supporter, cylinder body is fixed on bracing frame, simultaneously, the piston of cylinder body is connected with the end of lever.
Beneficial effect of the present invention: simple in structure, production cost is low; Simultaneously, make cylinder body away from the infrared source of hot flow path, effectively reduce the superheating phenomenon on every side of sealing ring, increase the service life of sealing ring, thereby increase the service life of cylinder; In addition, also effectively increased the dynamics of needle activity by lever, the high injection pressure production operation of effectively satisfying the demand.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of lever needle list mouth, as shown in Figure 1, comprise feed nozzle cap 1, side cylinder supporter 2, the center of described feed nozzle cap 1 is provided with charging hole, the lower end of feed nozzle cap 1 is connected with side cylinder supporter 2, and the charging hole of feed nozzle cap 1 is corresponding with the feeding-passage of side cylinder supporter 2, the lower end of side cylinder supporter 2 is provided with chovr body 4, chovr body 4 central longitudinal are to being provided with feeding-passage, and feeding-passage is skewed, side cylinder supporter 2 is close to and heater 3 with the outside of chovr body 4, the upper end of chovr body 4 communicates with the feeding-passage of side cylinder supporter 2, the lower end of chovr body 4 communicates with the centre bore of nozzle body 5, nozzle body 5 upper end outer race have nozzle holder 6, the lower end of nozzle body 5 is connected with discharging gate cap 7, the outer heater 3 that also is glued with of nozzle body 5, be inserted with needle 8 in the centre bore of nozzle body 5, the tapered bottom end of needle 8 is corresponding with the interior hole shape of discharging gate cap 7, the top of needle 8 withstands on the recess position of an end of lever 9, lever 9 is rotatably connected on bracing frame 12, bracing frame 12 is fixed on side cylinder supporter 2, cylinder body 11 is fixed on bracing frame 12, and, the piston 10 of cylinder body 11 is connected with the end of lever 9.In the actual implementation process of patent, client's mould and feed nozzle cap 1 closely cooperate and guarantee to advance with one heart glue, side cylinder supporter 2 guarantees with one heart by feed nozzle cap 1, and the plastics that feed nozzle cap 1 is come in are by heater 3 heating, and assurance plastics temperature is delivered to chovr body 4; Side cylinder supporter 2 and chovr body 4 closely cooperate and allow material turn to nozzle body 5, and simultaneously, chovr body 4 also needs heater 3 heat tracings; Material passes through the transition of chovr body 4 to nozzle body 5, nozzle body 5 and nozzle holder 6 closely cooperate, nozzle holder 6 and mould closely cooperate and guarantee that nozzle holder 6 and nozzle body 5 hold up nozzle body 5, chovr body 4, heater 3, side cylinder supporter 2, feed nozzle cap 1 with one heart simultaneously, and then material flows to discharging gate cap 7 by nozzle body 5, and flow to product by the cast gate of discharging gate cap 7, simultaneously, outside, the end of discharging gate cap 7 and client's mould close-fitting guarantee not expose with one heart plastics.Angle cooperation by needle 8 and discharging gate cap 7 when the product injection moulding is full is shut material in discharging gate cap 7; In real work, needle 8 plays envelope material effect by the transmission of lever 9; Lever 9 plays the rotation effect by the promotion of piston 10, and piston 10 and cylinder body 11 play the promotion effect by the turnover of gas; Cylinder body 11 is fixed on side cylinder supporter 2 by the good fixing effect of bracing frame 12.
Those ordinary skill in the art's simple change and replacement are all within protection scope of the present invention.
