The solid plastics input barrel of shape, plastifies into the good plastic melt of the plasticity with uniform density, viscosity and composition, then
By applying, certain pressure makes this kind of plastic melt possess certain flow rate and injected into the die cavity of mould, and plastics melt
After body cooling and shaping, the plastic products consistent with die profile are just can obtain.In injection-moulding device conventional at present, typically
Upon completion of the injection, the molten plastic of shower nozzle inwall is trapped in cooled and solidified little particle etc., so that shower nozzle can be blocked, so as to need
The inwall of shower nozzle is cleared up in time, in addition, screw rod is in the mistake for being pushed, be compacted, being vented and being plastified to plastic raw materials
Cheng Zhong, because having gap between the spiral shell rib and material tube inner wall on screw rod so that plastics are in " laminar flow " state motion in barrel,
Shearing force of the screw rod to plastics is limited, causes plastic molting uneven, easy-formation defective products.
Utility model content
The purpose of this utility model is to provide a kind of anti-clogging screw of injection mechanism, by the part in injection process
Heat transfer heating is carried out, injection mechanism is kept fluidity of molten in constant temperature, injection canal can also be entered after injection terminates
Row is rinsed, and removes retained material, also by improving plasticizing shear ability of the barrel to raw material, is reduced short grained generation, is made note
Penetrate raw materials melt uniform, injection volume is uniform, improve final product quality.
To achieve the above object, the utility model provides following technical scheme：A kind of anti-clogging screw of injection mechanism, including
Barrel, the screw rod in barrel is sequentially arranged in the contiguous block and nozzle of barrel discharging opening, one end of the contiguous block is provided with cone
The heating pipe of the taper charging aperture is provided around on shape charging aperture, the contiguous block, the heating pipe includes water inlet
And delivery port, guiding valve is provided between the contiguous block and nozzle, the guiding valve is with same with the tapping channel of contiguous block and nozzle
The material road of axle, be additionally provided with can be with the heating pipe the spout that saliva is connected that goes out, the guiding valve one end connection driving slide
Device.
The external hot water of water inlet of the heating pipe, makes tapered charging aperture keep steady temperature, is conducive to plastifying raw material
Smoothly injection is kept molten by, when drive device driving guiding valve is slided, material road and tapping channel is staggered and spout is accessed out
Expect that the hot water in passage, heating pipe is spouting by spout, tapping channel and nozzle are cleaned, remove block in time
Thing, prevents spray nozzle clogging.
Further, the internal perisporium of the barrel is provided with the helicla flute consistent with the hand of spiral of spiral shell rib on screw rod, institute
The spiral shell rib stated on screw rod is partially disposed in the helicla flute, and the screw rod is arranged with check ring close to one end of the contiguous block.
Screw rod applies shearing force with the common raw material in barrel of helicla flute, and raw material is carried significantly in the presence of twinshell
High plasticizing and mixing degree so that raw materials melt is uniform, beneficial to injection moulding.
Further, the contiguous block and nozzle are threaded connection, and filter screen is additionally provided between contiguous block and nozzle.
Further, the spout shrinks from width to narrow vertically, forms pressurization passageway, makes liquid formation pressurized jet.
Threaded connection can be conveniently replaceable different types of injection nozzle, adapt to different moulds, improve and change speed, filter screen
The little particle of omission can further be intercepted, it is to avoid be injected into mould.
Compared with prior art, the beneficial effects of the utility model are：Plastic raw materials are filled in barrel by screw rod and barrel
The plasticizing shearing divided, is fully melt into fluid, greatly reduces particulate matter, in injection process, the heat injected by heating pipe
Quantity of fluid makes injection mechanism keep constant temperature, therefore the temperature change of injection process is small, it is not easy to cause thermal stratification, can be evenly
Be injected into mould, when complete injection after, guiding valve close tapping channel, heating pipe injection heat liquid penetrating from spout
Go out, passage and nozzle cleaned, prevent block, it is ensured that the Forming Quality being molded each time, thus improve injector into
Quality.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, a kind of anti-clogging screw of injection mechanism, including barrel 1, the screw rod 11 in barrel 1, the material
