Individual second core rod, the formwork top is provided with top board, and the formwork lower section is provided with lower platen.
According to the technical scheme that the embodiment of the present application is provided, by designing a split shaping female mold, the core rod of former leads to
Cross two kinds of materials to be fabricated separately, and then reassemble together, both take into account the wearability of shaping female mold, had when design
Take into account the structural of product, and the core rod in the middle of shaping female mold also have outside with certain wearability it is certain
Toughness so that shaping female mold is not damaged by any resistance and pressed material, moreover it is possible to different according to the different structure choice of product
Mold materials, whole mould need not be scrapped when running into certain site tissue damage aborning, need to only change middle certain zero
Just, the shaping female mold changed after parts is identical with before in using effect for part, so not only saves a large amount of
Time, while also saving substantial amounts of cost and resource.
Description of the drawings
By reading the detailed description made to non-limiting example made with reference to the following drawings, the application other
Feature, objects and advantages will become more apparent upon：
Fig. 1 is to become displacement oil pump rotor shaping female mold top view in this utility model embodiment；
Fig. 2 is to become displacement oil pump rotor shaping female mold sectional view in this utility model embodiment.
Specific embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining relevant utility model, rather than the restriction to the utility model.Further need exist for explanation
, for the ease of description, the part related to utility model is illustrate only in accompanying drawing.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and in conjunction with the embodiments describing the application in detail.
Fig. 1 and Fig. 2 is refer to, this utility model embodiment provides a kind of change displacement oil pump rotor shaping female mold, bag
Include：Formwork 1, is provided with vertically through hole in the formwork 1, and interference fit has the first core rod 4 in the through hole of the formwork 1, and described the
Multiple second core rods 5 are installed, the formwork top is provided with top board 2, and the formwork lower section is provided with and pushes in one core rod 4
Plate 3.
The core rod of the change displacement oil pump rotor shaping female mold that this utility model embodiment is provided is by two kinds of materials point
Open making subsequently to be assembled, core rod and formwork are by together with interference fit so that the core rod in the middle of shaping female mold has
There are certain wearability and toughness so that shaping female mold is not damaged by any resistance and pressed material, is run in actual production
Whole mould need not be scrapped during certain site tissue damage, middle certain parts need to be only changed, the molding after parts is changed cloudy
Mould is identical with before in using effect, not only saves the plenty of time, while also saving substantial amounts of cost and money
Source.
Wherein, the second core rod 5 installed in the first core rod 4 can be selected and adjusted according to the different structure of product,
So that shaping female mold has more practicality.
Further, formwork 1 and the interference fit hot charging of first core rod 4.
Further, formwork is 40Cr formworks.
After formwork and the first core rod heat are installed with interference, then multiple second core rods for making will be polished by wire cutting
Overall die cavity is formed in the first core rod, wherein die casing material adopts 40Cr.
Further, the material of the first core rod 4 is differed with the material of the second core rod 5, and first core rod is YF25 moulds
Core, second core rod is 10V core rods.
Requirement of the shaping female mold to core rod is higher, certain toughness is also needed to outside with certain wearability, generally
Making core rod using a kind of material can easily cause in use the damage of core rod, and maintenance and replacing are all pretty troublesome, and
And expend the time, increase cost, therefore core rod is divided into into two parts, two kinds of materials are respectively adopted and make, using wearability compared with
Good YF25 used as the first core rod, as the second core rod with the use of increased using for shaping female mold imitate by the preferable 10V of toughness
Rate.
Further, the cylinder of through hole is provided with centered on the first core rod 4, along the inside diameter hoop direction of first core rod 4
It is interval with multiple second core rod holes.
By the first core rod elastic conjunction of cylinder in formwork, the first core rod center is provided with through hole, and the second core rod
Hole is also disposed at the first core rod inside diameter hoop direction, as shown in Fig. 2 the second core rod hole uniform intervals are arranged, and the second core rod hole
For through hole.
Further, the first core rod inside diameter hoop direction is uniformly provided with seven the second core rod holes, in the second core rod hole
It is respectively fitted with the second core rod
The second core rod provided in this utility model embodiment is provided with seven, and the first core rod is uniformly arranged on as far as possible
On inside diameter hoop.
Further, top board 2 is provided with the first counterbore 6, and the upper surface of the formwork 1 is provided with the first tapped blind hole 7, described
First tapped blind hole 7 is corresponding with first counterbore 6, is screwed with screw in first counterbore and first tapped blind hole, institute
State top board 2 to be fixed by screw with the formwork 1.
Further, lower platen 3 is provided with the second counterbore 8, and the lower surface of the formwork 1 is provided with the second tapped blind hole 9, described
Second tapped blind hole 9 is corresponding with second counterbore 8, is screwed with screw in second counterbore and second tapped blind hole, institute
State lower platen 3 to be fixed by screw with the formwork 1.
The formwork and the first core rod, the second core rod provided in this utility model embodiment is carried out by top board and lower platen
After fixation, formwork and the first core rod, the second core rod close-fitting are installed, upper lower platen is fixed by screw respectively, so
Core rod is received and also will not produce after external force loosening during molding.
Further, fastened by screw position one is located at formwork upper surface, and one is located at formwork lower surface, enters simultaneously up and down
Row fastener guarantee shaping female mold will not produce loosening.
This utility model embodiment provide lubricating oil pump rotor shaping female mold both take into account shaping female mold wearability,
Have and take into account the structural of product, and the core rod in the middle of shaping female mold also has necessarily outside with certain wearability
Toughness so that shaping female mold is not damaged by any resistance and pressed material, not only saves the plenty of time, while also saving
Substantial amounts of cost and resource.
