Abstract
The utility model discloses a kind of low pressure casting die segmented push rod, it comprises push rod upper end and push rod lower end, the afterbody of described push rod upper end is provided with the draw-in groove for inserting described push rod lower end, the diameter of described draw-in groove internal diameter and described push rod lower end matches, and described push rod lower end is inserted in described draw-in groove.The utility model, for the flimsy shortcoming in integral type push rod lower end, changes integral type push rod into segmentation structure, and the draw-in groove of segmented push rod lower end aligned segmented push rod upper end inserts.Mould changes wherein flimsy push rod lower end after using some cycles.The deficiency that the utility model structure is simple, easy to operate, compensate for integral type push rod integral replacing high cost in pressure cast aluminum-alloy wheel casting mould, guarantees the validity of mold actions, greatly reduces cost simultaneously.
Description
Technical field
The utility model relates to a kind of low pressure casting die segmented push rod.
Background technology
At present, Low Pressure Casting Technology has been widely used in the making of aluminium alloy wheel hub, and present aluminium alloy wheel hub production technology mainly adopts low pressure casting and gravity casting method; And the aluminium alloy wheel hub of about 90% is produced with low-pressure casting process at present.
In the production process of low pressure casting aluminum alloy wheel hub, low pressure casting die all uses integral type push rod ejection system to make blank break away from moulds, all need directly to contact with the blank of hundreds of degree Celsius because integral type ejector rod system ejects at every turn, cause the integral type push rod lower end corrosion and damage in ejection system, so each mould all needs the integral type push rod changed in whole ejector rod system after using some cycles, production cost is increased greatly.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of low pressure casting die segmented push rod that can reduce pressure cast aluminum-alloy wheel casting mould push rod cost.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of low pressure casting die segmented of the utility model push rod, it comprises push rod upper end and push rod lower end, the afterbody of described push rod upper end is provided with the draw-in groove for inserting described push rod lower end, the diameter of described draw-in groove internal diameter and described push rod lower end matches, and described push rod lower end is inserted in described draw-in groove.
The utility model, for the flimsy shortcoming in integral type push rod lower end, changes integral type push rod into segmentation structure, and the draw-in groove of segmented push rod lower end aligned segmented push rod upper end inserts.Mould changes wherein flimsy push rod lower end after using some cycles.
The beneficial effect that the utility model reaches is:
The deficiency that the utility model structure is simple, easy to operate, compensate for integral type push rod integral replacing high cost in pressure cast aluminum-alloy wheel casting mould, guarantees the validity of mold actions, greatly reduces cost simultaneously.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of push rod upper end;
Fig. 3 is the structural representation of push rod lower end.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 3, a kind of low pressure casting die segmented of the utility model push rod, it comprises push rod upper end 1 and push rod lower end 2, the afterbody of described push rod upper end 1 is provided with the draw-in groove 3 for inserting described push rod lower end 2, the diameter of described draw-in groove 3 internal diameter and described push rod lower end 2 matches, and described push rod lower end 2 is inserted in described draw-in groove 3.
The utility model, for the flimsy shortcoming in integral type push rod lower end, changes integral type push rod into segmentation structure, and the draw-in groove 3 that push rod upper end 1 is aimed in the push rod lower end 2 of segmented inserts.Mould changes wherein flimsy push rod lower end after using some cycles.
The deficiency that the utility model structure is simple, easy to operate, compensate for integral type push rod integral replacing high cost in pressure cast aluminum-alloy wheel casting mould, guarantees the validity of mold actions, greatly reduces cost simultaneously.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
