Abstract
The utility model discloses an oil-taking inner pipe molding core for an upper cover of an automobile fuel oil pump assembly. The oil-taking inner pipe molding core comprises an outer body and an inner body, wherein the outer body is provided with a core hole; the inner body is arranged in the core hole in a sliding mode, and comprises an outer casing pipe molding cylinder and an inner connection pipe molding shaft in the center of the outer casing pipe molding cylinder; and the lower part, opposite to the outer casing pipe molding cylinder, of the inner body is provided with a side clamping plate molding groove. The oil-taking inner pipe molding core provided by the utility model has the advantages that a side clamping plate can be smoothly manufactured on an oil-taking inner pipe; components are convenient to manufacture; and the stability is high.
Description
Technical field
The utility model relates to a kind of injection mold, specifically refers to a kind of oil-feed inner tube building core of vehicle fuel pump assembly upper cover.
Background technology
The effect of vehicle fuel pump assembly is to deliver in the fuel pipe of engine nozzle after the fuel oil pressurization that will be stored in fuel tank, and then is the automobile engine fuel feeding.Wherein vehicle fuel pump assembly upper cover is the middle vitals of vehicle fuel pump assembly, is provided with inlet nozzle, oil return nozzle on vehicle fuel pump assembly upper cover, the mechanisms such as oil-feed inner tube, oil return inner tube, connector socket, connection guide pillar, and its integral body is a plastic part.The structure of the oil-feed inner tube of traditional vehicle fuel pump assembly upper cover comprises inner connecting tube and the outer tube concentric with inner tube, and this structure is poor at stable connection.Therefore, for the connective stability of the pipeline in the pump housing that ensures oil-feed inner tube and vehicle fuel pump assembly, the lower edge projection of the oil-feed inner tube of new vehicle fuel pump assembly upper cover is provided with the side clamp, is provided with hole clipping 2' on this side clamp 1', as shown in Figure 1.For this reason, be necessary oil-feed inner tube building core is improved design, to adapt to the moulding of side clamp.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and provides a kind of for the building core of processing and forming with the oil-feed inner tube of side clamp, to improve the connective stability of oil-feed inner tube.
For achieving the above object, the technical solution of the utility model is to comprise oil-feed inner tube core ectosome and oil-feed inner tube core endosome, be provided with the core hole on described oil-feed inner tube core ectosome, described oil-feed inner tube core endosome is mounted slidably in this core hole, described oil-feed inner tube core endosome includes the outer tube forming tube and is arranged at the inner connecting tube shaping axle at outer tube forming tube center, and the lower position of the relative outer tube forming tube of described oil-feed inner tube core endosome is provided with side clamp forming tank.By this setting, by oil-feed inner tube building core being resolved into oily inner tube core ectosome and two monomers of oil-feed inner tube core endosome, can be provided for easily the side clamp forming tank of process side clamp on oil-feed inner tube core endosome, thus, realize that easily the moulding processing belt has the purpose of the oil-feed inner tube of side clamp, production high efficient and reliable.
Further arrange is to be provided with the core-drawing hole corresponding with side clamp forming tank position on the sidewall of described oil-feed inner tube core ectosome.Owing to can be provided with square hole clipping on the side clamp, its moulding operation of need to loosing core, by this setting, core-drawing hole can facilitate core_pulling pole turnover side clamp forming tank, the operation of conveniently loosing core.
In sum, the utility model has the advantages that, realize smoothly process side clamp on the oil-feed inner tube, and component processing is convenient, good stability.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
