Abstract
The invention provides a plasticizing part of an injection molding machine. The plasticizing part comprises a cylinder, a screw, and a screw head. The screw head extends into the cylinder, and is fixedly held with the screw. The plasticizing part (100) also comprises a check ring and a check pad arranged inside the cylinder. The screw head respectively extends into the check ring and the check pad, and is fixedly held with the screw. The check ring is a hollow cylindrical cylinder. A first axial annular surface of the check ring is provided with a plurality of protruding sections. The protruding sections abut against the screw head. A second axial annular surface of the check ring abuts against the check pad. According to the invention, the check ring and the check pad are arranged between the screw head and the screw, such that materials can be prevented from back-flowing during an injection molding process of the injection molding machine, and thereby the injection molding effect and the production efficiency of the injection molding machine are improved.
Description
Technical field
The invention belongs to injection machine accessory technical field, relate in particular to a kind of plasticizing parts of injection machine.
Background technology
In living in modern times, employed plastic products in our daily life, for example the plastic products such as control panel of toy, household electrical appliance normally adopt injection machine, and the mould integral molding of supporting use given shape.
Injection machine comprises a plasticizing process usually in injection moulding process.So-called plasticizing just is meant that material reaches flow regime through heating in the barrel of injection machine, and has good plastic overall process.
Join shown in Figure 1ly, Fig. 1 is the cutaway view of the plasticizing parts of a kind of injection machine of the prior art.In the prior art, the material (not shown) in the plasticizing parts 200 through machine barrel 22, is expelled in the die cavity (not shown) of specific mould through screw head 23 under the rotation of screw rod 21 promotes at last, to accomplish injection moulding process.
Yet the phenomenon of feed back in the process that material is penetrated, can take place in plasticizing parts of the prior art, thereby causes the phenomenon of injection moulding poor effect to take place.And machine barrel 22 and place, the dead angle between the screw head 23 that the material that refluxes tends in the plasticizing parts form residual clout.These residual clouts can pollute the material of heterogeneity, thereby cause the injection moulding poor effect.
In view of this, be necessary the plasticizing parts of injection machine of the prior art are improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of plasticizing parts of injection machine, it can prevent the generation of injection machine feed back phenomenon in injection moulding process effectively, improves the injection moulding effect of injection machine, improves and produces moulding production efficiency.
Be to realize the foregoing invention purpose, the invention provides a kind of plasticizing parts of injection machine, it comprises, machine barrel, screw rod, screw head, said screw head extends into machine barrel inside, and with screw rod fixing mutually, said plasticizing parts also comprise,
Be arranged at said machine barrel inner non-return ring and non-return pad; Said screw head extends into said non-return ring and non-return pad successively; And with screw rod fixing mutually; Said non-return ring is the hollow cylindrical cylindrical shell, and the first axial anchor ring of said non-return ring is provided with several protuberances, and said protuberance and screw head lean; The second axial anchor ring and the said non-return pad of said non-return ring lean.
As further improvement of the present invention, said protuberance distributes and the said first axial anchor ring along the axis of said non-return ring symmetrically and evenly.
Compared with prior art; The invention has the beneficial effects as follows: through non-return ring and non-return pad are set between screw head and screw rod; Can prevent injection machine effectively in injection moulding process, the generation of feed back phenomenon, thus improved the injection moulding effect and the production efficiency of injection machine.

The specific embodiment
Below in conjunction with each embodiment shown in the drawings the present invention is elaborated; But should be noted that; These embodiments are not limitation of the present invention; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Please join shown in Figure 2ly, Fig. 2 is the cutaway view in plasticizing parts one specific embodiment of a kind of injection machine of the present invention.In this embodiment, a kind of plasticizing parts 100 of injection machine, it comprises, machine barrel 10, screw rod 20, screw head 30.This screw head 30 extends into machine barrel 10 inside, and with screw rod 20 fixing mutually.In this embodiment, these plasticizing parts 100 also comprise, are arranged at machine barrel 10 inner non-return ring 40 and non-return pad 50, and screw head 30 extends into non-return ring 40 and non-return pad 50 successively, and with screw rod 20 fixing mutually.
In conjunction with Fig. 3 and shown in Figure 4, this non-return ring 40 is the hollow cylindrical cylindrical shell, and the first axial anchor ring 401 of this non-return ring 40 is provided with two protuberances 411, and this protuberance 411 leans with screw head 30.The second axial anchor ring 402 of this non-return ring 40 leans with this non-return pad 50.
In injection moulding process, screw rod 20 self rotates, and moves to screw head 30 directions thereby promote material.In this embodiment, the internal diameter of this non-return ring 40 is greater than the external diameter of this screw rod 20.Thereby material is injected in the mold cavity from screw head 30 from the gap between screw rod 20 and the non-return ring 40, accomplish injection moulding process.
In this embodiment, this non-return ring 40 keeps certain axial distance between screw head 30 and non-return pad 50.If material refluxes, non-return ring 40 can be shunk back to non-return pad 50, thereby under the acting in conjunction of non-return ring 40 and non-return pad 50, forms back leakage seal, makes the material of screw head 30 front ends can not be back to machine barrel 10 inside.
In this embodiment, this protuberance 411 is distributed in this first axial anchor ring 401 symmetrically and evenly along the axis 42 of non-return ring 40.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any Reference numeral in the claim be regarded as limit related claim.
In addition; Describing according to embodiment though should be appreciated that this specification, is not that each embodiment only comprises an independently technical scheme; This narrating mode of specification only is for clarity sake; Those skilled in the art should make specification as a whole, and the technical scheme among each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
