Description
Technical field
The utility model relates to a kind of injection machine, specifically, relates to a kind of nozzle for injection machine.
Background technology
Injection machine has another name called injection (mo(u)lding) machine or injector, and it thermoplastic or thermosetting plastics is utilized mould for plastics to make the main former of the plastic products of various shape.Along with plastic articles is in the extensive use of industrial circle, also more and more higher to the requirement of injection moulding.The nozzle of existing injection machine is after having injected, and molten plastic can produce wire drawing and prolong flow phenomenon, and when particularly molten plastic ratio of viscosities is lower, it is more outstanding that flow phenomenon is prolonged in wire drawing.When die sinking, the molten plastic of wire drawing will mold damage.
Utility model content
The technical problems to be solved in the utility model is, for the deficiency that existing nozzle exists, provides a kind of nozzle for injection machine, and it can solve the problem that stream is prolonged in wire drawing existing in prior art.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of nozzle for injection machine, described nozzle is revolving body, described nozzle offers centre bore, described nozzle has the first end entered for molten plastic and the second end exported for molten plastic, wherein said centre bore has the first taper hole section of being arranged successively towards described second extreme direction by described first end, first circular hole portion, second taper hole section, second circular hole portion and the 3rd taper hole section, described first taper hole section and described second taper hole section are greater than the circumferential size away from described first end near the circumferential size of described first end, described 3rd taper hole section is less than the circumferential size away from described first end near the circumferential size of described first end.
As preferably, the outer surface of described nozzle is provided with external screw thread near the position of described first end.
As preferably, described external screw thread is provided with flange away from the side of described first end.
As preferably, the outer surface of described nozzle is provided with muff.
As preferably, the material of described muff is rubber.
As preferably, described second end is arc tips.
Implement the nozzle for injection machine of the present utility model, there is following beneficial effect: select the first taper hole section, the second taper hole section, after nozzle work is complete, the amount of its molten plastic reduces gradually, effectively prevents wire drawing from prolonging the generation of flow phenomenon.In addition, the 3rd taper hole section is set, nozzle can be ensured operationally, provide enough molten plastic to mould.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the sectional structure schematic diagram of the nozzle for injection machine of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is further described.
With reference to shown in Fig. 1, the utility model discloses a kind of nozzle for injection machine, this nozzle is revolving body, cylindrical.Nozzle offers centre bore, and nozzle has the first end 1 (being directly connected with feed section) entered for molten plastic and the second end 2 exported for molten plastic.Wherein, this centre bore has first taper hole section 3, first circular hole portion 4, second taper hole section 5, second circular hole portion 6 and the 3rd taper hole section 7 of being arranged successively towards the second end 2 direction () by first end 1 in figure in top-down direction, and these five sections connect successively.First taper hole section 3 and the second taper hole section 5 are greater than the circumferential size away from first end 1 near the circumferential size of first end 1, and namely the first taper hole section 3 and the second taper hole section 5 are in contraction-like.It is easily understood that the circumferential size of the first circular hole portion 4 is greater than the circumferential size of the second circular hole portion 6.3rd taper hole section 7 is less than the circumferential size away from first end 1 near the circumferential size of first end 1, and namely the 3rd taper hole section 7 is in divergent shape.
After nozzle work is complete, the amount of its molten plastic reduces gradually, effectively prevents wire drawing from prolonging the generation of flow phenomenon.In addition, the setting of the 3rd taper hole section 7 can ensure nozzle operationally, ensures the supply of enough molten plastics.
As a kind of mode, the second end 2 of nozzle is arc tips, is convenient to the good fit of the 3rd taper hole section 7 and mould.As shown in FIG., this arc tips is the arc tips of evagination.
In the utility model, the outer surface of nozzle is provided with external screw thread 8 near the position of first end 1, nozzle can be connected with injection machine by this external screw thread 8.In addition, external screw thread 8 is provided with flange 9 away from the side of first end 1, and this flange 9 convenient operation personnel grip this nozzle, to carry out dismounting.
In addition, in the utility model, the outer surface of nozzle is provided with muff 10.This muff 10, for ensureing the temperature of nozzle, is avoided at molten plastic in the cooling of nozzle position, thus is ensured the good fluidity of molten plastic, to obtain good molding effect in a mold.The material of this muff 10 can be chosen as multiple, such as existing various insulation material, and as a kind of mode, the material of muff 10 is rubber.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
