Abstract
The utility model relates to an injection mold for manufacturing a fiber reinforced composite eccentric wear prevention continuous sucker rod. The technical scheme is as follows: the injection mold is characterized by comprising glue injection nozzles, vacuum nozzles, a resin matrix glue solution cavity, a right mold housing, a left plug body, a right plug body and a left mold housing, wherein the right mold housing and the left mold housing form an injection mold main body; the left plug body and the right plug body are respectively arranged at both ends of the injection mold main body; the resin matrix glue solution cavity is arranged between the left plug body and the right plug body; and the top of the injection mold main body is provided with one or more vacuum nozzles, and the bottom of the injection mold main body is provided with one or more glue injection nozzles. The injection mold has the beneficial effects that an open type glue dipping tank in the traditional pultrusion process is canceled, the glue solution is injected in an injection mold cavity by an injection machine, and fibers without glue-dipping directly enter the injection mold and are mixed and dipped with the glue solution inside the mold cavity, so that the influence of the environment on the glue solution and the influence of non-uniform mixing of new and old glue solutions on craft and product quality are avoided, the freshness degree of the glue solution used during the production is ensured, and continuous stability of production is improved.
Description
Technical field
The utility model relates to a kind of preparation facilities of petroleum industry oil production equipment, particularly prevents the injection molding of eccentric wear coiled rod for the manufacture of fibre reinforced composites.
Background technology
Because the Oil Reservoir Types of exploitation becomes increasingly complex, the continuous deterioration of the simultaneously continuous increase of well depth and well ore deposit environment, corrosion and eccentric wear problem become oil extraction in oil field technique problem demanding prompt solution.Because possess the corrosion resistant characteristics of high-strength light, so the composite sucker rod has begun progressively to replace traditional metal sucker rod.The composite sucker rod that adopts at present mainly comprises glass fiber reinforced plastic oil pumping rod and the large class of carbon fibre reinforced composite coiled rod two.Glass fiber reinforced plastic oil pumping rod adopts the pultrude process one-shot forming preparation of glass-fiber reinforced thermo-setting resin, extensive use, but along with the reliability requirement of modern times oil recovery improves constantly, glass fiber reinforced plastic oil pumping rod can not meet the demands, mainly there is following problem, 1, the anti-eccentric wear of sucker rod is bad; 2, fatigue strength is inadequate; 3, the equal fixed length of glass fiber reinforced plastic oil pumping rod, respectively there is a metal joint at two ends, adopt the metal box cupling of metal pumping rod application to be connected between root and root, and due to complex structure, difficulty of processing is large, and is expensive.Each root glass fiber reinforced plastic oil pumping rod is with two metal joints, and the cost of these two metal joints is far above the cost of a fiberglass body of rod; Compare with the traditional metal sucker rod in addition, except shank portion has been changed material, other parts of whole rod string there is no change, traditional metal rod string joint is many, breaking, it is high to take off probability, and piston effect is obvious, and the serious problem of box cupling and oil pipe eccentric wear is not resolved.
In addition, in traditional pultrude process, in open glue groove, glue contacts with air for a long time, a small amount of reaction gel, and the backflow that reaches unnecessary resin causes the new and old inequality of glue in the glue groove, causes properties of product to reduce, and the technique continuity is relatively poor.
The utility model content
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, be provided for making the injection molding of the anti-eccentric wear coiled rod of fibre reinforced composites, avoided impact and the new and old glue mixing uneven impact on technique and product quality of environmental factor on glue, guarantee to produce the freshness of glue used, improved the continous-stable of producing.
The technical solution of the utility model is: comprise adhesive pouring nozzle, vacuum nozzle, resin matrix glue chamber, mould right shell body, left cock body, right cock body, mould left shell, described mould right shell body and mould left shell form the injection molding main body, the two ends of injection molding main body are respectively equipped with left cock body and right cock body, and the centre is resin matrix glue chamber; The top of described injection molding main body is provided with one or more vacuum nozzle, and the bottom is provided with one or more adhesive pouring nozzle.
Above-mentioned mould right shell body and mould left shell are bolted together.
The beneficial effects of the utility model are: cancelled steeping vat open in traditional pultrude process, change injector injection glue into to the injection molding die cavity, do not have the fiber of impregnation directly to enter in injection molding, with the glue hybrid infusion in mold cavity, avoided impact and the new and old glue mixing uneven impact on technique and product quality of environmental factor on glue, guarantee to produce the freshness of glue used, improved the continous-stable of producing.

In upper figure: adhesive pouring nozzle 4.1, vacuum nozzle 4.2, resin matrix glue chamber 4.3, mould right shell body 4.4, left cock body 4.5, right cock body 4.6, bolt 4.7, mould left shell 4.8.
The specific embodiment
With reference to accompanying drawing 1, the utility model comprises adhesive pouring nozzle 4.1, vacuum nozzle 4.2, resin matrix glue chamber 4.3, mould right shell body 4.4, left cock body 4.5, right cock body 4.6, mould left shell 4.8, described mould right shell body 4.4 forms the injection molding main body with mould left shell 4.8, the two ends of injection molding main body are respectively equipped with left cock body 4.5 and right cock body 4.6, and the centre is resin matrix glue chamber 4.3; The top of described injection molding main body is provided with one or more vacuum nozzle 4.2, and the bottom is provided with one or more adhesive pouring nozzle 4.1; Above-mentioned mould right shell body 4.4 links together by bolt 4.7 with mould left shell 4.8.
During work, the external vacuum tube of vacuum nozzle, vacuum tube is connected with vacuum tank, and vacuum tank is controlled by vavuum pump, continue to keep when producing 〉=-vacuum of 0.85MPa; Described injector is passed through the adhesive pouring nozzle of bottom to the inner resin by injection Matrix adhesive of injection molding.Cancelled steeping vat open in traditional pultrude process, change injector injection glue into to the injection molding die cavity, do not have the fiber of impregnation directly to enter in injection molding, with the glue hybrid infusion in mold cavity, avoided impact and the new and old glue mixing uneven impact on technique and product quality of environmental factor on glue, guarantee to produce the freshness of glue used, improved the continous-stable of producing.
With reference to accompanying drawing 2, the fiber reinforced resin based composite material body of rod b that makes, its cross sectional shape is for just round or oval, and its continuous length is generally 0～5000m, thermoplastic wearing layer a, its thickness is generally 1～10mm, in the longitudinal direction, in the sucker rod body of rod and the corresponding position appearance of oil pipe eccentric wear well section, it can be only continuous one section, can be interrupted several sections, all the other positions of the body of rod do not need all to adhere to wearing layer yet.
