Abstract
The utility model discloses a movable die core base of a forming die for an upper cover of an automobile fuel oil pump assembly. The movable die core base comprises a main body, wherein an upper cover inner surface forming body is arranged on the main body in an embossing way; and an oil inlet inner pipe mold core installing hole, an oil returning inner pipe mold core installing hole and a connecting guide column mold core installing hole are respectively formed in the upper cover inner surface forming body. The movable die core base can be reused, so that the development expenses and cost of the die can be effectively decreased.
Description
Technical field
The utility model relates to a kind of injection forming mold, specifically refers to a kind of moving-mould-core matrix of mould 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, be 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, its integral body is a plastic part, and adopts injection molding to process.The structure of the mould of existing a kind of vehicle fuel pump assembly upper cover has generally comprised by quiet mould and dynamic model, and it is installed on and carries out injection molding operation on the injection moulding lathe.Wherein be provided with moving-mould-core on dynamic model, a plurality of moulding positions be set on this moving-mould-core, be respectively used to the moulding upper cover oil-feed inner tube 1', oil return inner tube 2', connect the position such as guide pillar 3', as shown in Figure 1.Yet each moulding position on the moving-mould-core of the mould of traditional vehicle fuel pump assembly upper cover and moving-mould-core matrix are connected one to be connected and arranges, and causes every cover moving-mould-core can only process the assembly upper cover of a specific standard.Yet size and the position of the vehicle fuel pump assembly upper cover on different automobiles have difference, therefore need to process accordingly a plurality of inner membrance cores, cause the Mould Machining cost high.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and provide a kind of moving-mould-core matrix of mould of vehicle fuel pump assembly upper cover, this moving-mould-core matrix can be applicable to the upper cover processing and forming of different size, therefore can reduce mould development cost and expense.
For achieving the above object, the technical solution of the utility model is to include body, on described body, projection is provided with upper cover inner face formed body, is respectively arranged with oil-feed inner tube core installing hole, oil return inner tube core installing hole on described upper cover inner face formed body and is connected guide pillar core installing hole.By this setting, moving-mould-core with traditional one, be modified as the moving-mould-core matrix with the core installing hole of the present utility model, by oily inner tube core, the oil return inner tube core of different size being installed on this moving-mould-core matrix and being connected the guide pillar core, can realize processing the assembly upper cover of different size, therefore, by this setting, this moving-mould-core matrix can repeatedly use, and has effectively reduced the development cost of mould.
The sidepiece that further setting is corresponding oil-feed inner tube core installing hole on described upper cover inner face formed body is provided with core-drawing hole.Because the lower end of the oil-feed inner tube of assembly upper cover can be provided with the side clamp, can be provided with square hole clipping on this side clamp, its moulding operation of need to loosing core, by this setting, core-drawing hole can facilitate core_pulling pole turnover moving-mould-core, the operation of conveniently loosing core.
Further arrange is to be provided with a plurality of guide pillar holes that are parallel to each other that connect its upper and lower surface on described body.
In sum, moving-mould-core matrix of the present utility model can be reused, and effectively reduces mould development expense and cost.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Description of drawings
The structural representation of Fig. 1 vehicle fuel pump assembly upper cover;
Fig. 2 the utility model specific embodiment structural representation;
Fig. 3 the utility model is installed the structure reference diagram of each core.
The specific embodiment
Below by embodiment, the utility model is carried out concrete description; only be used for the utility model is further illustrated; can not be interpreted as the restriction to the utility model protection domain, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned utility model.
The specific embodiment of the present utility model as Figure 1-3, include body 1, on described body 1, projection is provided with upper cover inner face formed body 2, be respectively arranged with oil-feed inner tube core installing hole 21, oil return inner tube core installing hole 22 on described upper cover inner face formed body 2 and be connected guide pillar core installing hole 23, with reference to as shown in 2-3.In addition, on the described upper cover inner face of the present embodiment formed body 2, the sidepiece of corresponding oil-feed inner tube core installing hole is provided with core-drawing hole 24.
In addition, the guide pillar hole 11 that is provided with on the described body 1 of the present embodiment that connect its upper and lower surface a plurality of are parallel to each other.
Claims (3)
