Abstract
The utility model discloses a rubber stator molding clamp which aims at overcoming the defects in the prior art of complex rubber injection process and inaccurate stator molding size caused by the fact that a rubber injection opening needs repair after rubber is injected into a screw pump stator. The rubber stator molding clamp comprises a clamp, a mold core, a metal steel sleeve and rubber, wherein the clamp is used for clamping two ends of the mold core; the metal steel sleeve sleeves the periphery of the mold core; the rubber fills the space between the metal steel sleeve and the mold core; an opening is horizontally formed in one end of the metal steel sleeve. The rubber stator molding clamp is simple in structure; stators produced with the clamp are accurate in size; moreover, a screw pump is free of material leakage and the like during running.
Description
Technical field
The present invention relates to a kind of shaping jig, particularly a kind of elastomer stator shaping jig.
Background technology
Screw pump is that a kind of pump housing and formed engagement spatial volume of screw rod of relying on changes and the mobile drum pump of carrying liquid or making it supercharging.
Screw pump stator is in screw pump, to hold flimsy strength member, its dimensional accuracy and moulding process have influence on the service life of elastomer stator, existing screw pump stator, as shown in Figure 1, it adopts vertical injection process to its elastomer stator shaping jig 1A, when vertical injecting glue, need in the middle of steel bushing 2A, open injection orifice 3A, therefore under the injection of large pressure, core rod 4A easily produces deformation, therefore the compact dimensions inaccuracy of stator; For avoiding screw pump to produce the phenomenons such as leaked substance in running, after completing injecting glue, need to try every possible means gum-injecting port to repair in addition; Therefore complex process.
Therefore be necessary to develop a kind of new elastomer stator shaping jig, make up above-mentioned defect.
Summary of the invention
The present invention proposes a kind of elastomer stator shaping jig, thereby solved, needs to repair gum-injecting port cause the complicated and coarse defect of stator compact dimensions of injection process in prior art after screw pump stator injecting glue.The present invention is simple in structure, and its stator dimensions of producing is accurate, and has avoided screw pump in running, to produce the phenomenons such as leaked substance.
Technical scheme of the present invention is achieved in that
An elastomer stator shaping jig, it comprises fixture, core rod, metal steel bushing and rubber; Described fixture is folded in described core rod two ends; It is peripheral that described metallic steel is set in described core rod; Described rubber filling is between described metal steel bushing and described core rod; And described metal steel bushing one end level is provided with opening.
Further, described fixture is provided with gum-injecting port near one end of described opening, and described gum-injecting port and described open communication.
The present invention is simple in structure, by horizontal rubber injection machine, rubber level is injected between core rod and metal steel bushing, therefore in injecting glue process, mould core of stator can crimp, make stator moulding after size accurate; And moulding stator product does not have hole for injecting glue position, reduced and repaired the processing step of hole for injecting glue position, and avoided screw pump in running, to produce the phenomenons such as seepage material
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of prior art elastomer stator shaping jig;
Fig. 2 is the structural representation of elastomer stator shaping jig of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
With reference to Fig. 2, a kind of elastomer stator shaping jig 1, it comprises fixture 2, core rod 3, metal steel bushing 4 and rubber 5; Described fixture 2 is folded in described core rod 3 two ends; Described metal steel bushing 4 is set in described core rod 3 peripheries; Described rubber 5 is filled between described metal steel bushing 4 and described core rod 3; And described metal steel bushing 4 one end levels are provided with opening 41.
Further, described fixture 2 is provided with gum-injecting port 21 near one end of described opening 41, and described gum-injecting port and described open communication.Gum-injecting port of the present invention is communicated between metal steel bushing and core rod, therefore while using rubber injection agent injecting glue, directly, from gum-injecting port injection, rubber can be filled between metal steel bushing and core rod.
The stator moulding process of elastomer stator shaping jig of the present invention comprises the steps: that (1) is set in metal steel bushing the periphery of core rod, is provided with gap between core rod and metal steel bushing; (2) fixture is folded in to the two ends of core rod, rolling clamp, makes the gum-injecting port on fixture all be communicated with the opening that gap, metallic steel put; (3) by horizontal rubber injection machine, aim at gum-injecting port, rubber level is injected in gap; (4) after sulfuration sizing, fixture, metal steel bushing and core rod are taken off, obtain elastomer stator finished product.
Compared with prior art, tool has the following advantages in the present invention:
In use, by horizontal rubber injection machine, by rubber, the mode by horizontal injecting glue will be injected between core rod and metal steel bushing elastomer stator shaping jig of the present invention, therefore in injecting glue process, mould core of stator can crimp, make stator moulding after size accurate; And moulding stator product does not have hole for injecting glue position, reduced and repaired the processing step of hole for injecting glue position, and avoided screw pump in running, to produce the phenomenons such as seepage material.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
