The invention discloses the combined member of a kind of core and stud, this component includes stud and core；Stud includes support body, and the top of support body is provided with fastener, and support body is provided with clamping inner arc surface, and the end of clamping circular arc is provided with opposing parallel two clamping part, and clamping part has free end；Described core includes core body, core body arranges multiple core groove, described core groove is provided with seam, seam one transverse plane and core groove external arc joint are provided with projection, angle between described projection and seam two plane is 40 ° ~ 50 °, the width dimensions being dimensioned slightly smaller than between two described clamping parts of seam.This component core and stud rigid contact, combining structure good rigidly, stud intensity is high, stud is good to core supporting effect, stud can make of common material and common process simultaneously, core can be completed by manual or simple and mechanical device with stud combination assembling, and cost of manufacture and the installation cost of component are low.
Description
Technical field
The invention belongs to casting device, be specifically related to the combined member of a kind of core and stud.
Background technology
During castings production, core is fixed mainly by core print in die cavity, but core is only fixed by core print sometimes
Position is difficult to consolidate, and reinforces core frequently with stud the most aborning, to play the work that auxiliary supports
With.
Stud in the application need pay close attention to intensity and with foundry goods body fusion character of both problem.First, exist
Before die cavity medium casting solidifies the most completely, stud self should have enough intensity, should in die cavity not too early
Melt and make intensity decline and cause the stud forfeiture to core supporting role；Its two be stud likely because of with casting
Part lack of fusion and cause pore, or do not fuse, cause casting section to there is mortality defect.
The structure of existing conventional chaplet core is to reinforce core, this ruggedized construction with elastic stud
The elasticity of stud is relatively good, but its shortcoming to be the rigidity of stud poor, the insufficient strength of stud self, hold
It is easily caused the stud forfeiture to core supporting role；And owing to stud needs to be fabricated to elastic construction, to core
The making material of support and manufacture craft are proposed higher requirement, meanwhile, when core and stud combination assembling
It is also required to special plant equipment and carries out auxiliary installation, expend substantial amounts of manpower and materials.
Summary of the invention
It is an object of the invention to provide the combined member of a kind of core and stud, core and stud rigid contact,
Combining structure good rigidly, intensity is high, and supporting effect is good, and cost of manufacture and installation cost are low simultaneously.
For achieving the above object, the technical solution used in the present invention is:
This component includes stud and core；Stud includes support body, and the top of support body is provided with fastener, and support body sets
Being equipped with inner arc surface, the end of clamping circular arc is provided with opposing parallel two clamping part, and clamping part has certainly
By holding；Described core includes core body, arranges multiple core groove on core body, and described core groove is provided with seam, only
It is protruding that mouth one transverse plane and core groove external arc joint are provided with arc-shaped, and the center of circle of described projection is to protruding
(25) angle between ray and seam plane that arcuate midway point is formed is 40 °～50 °, the width of seam
It is dimensioned slightly smaller than the width dimensions between two described clamping parts.
Preferably, the width of core groove is not less than the thickness of stud.
Preferably, transition seam it is provided with between core groove external arc and projection.
What this combined member produced has the beneficial effect that this component core and stud rigid contact, and combining structure is firm
Property good, stud intensity is high, and stud is good to core supporting effect, and stud can be with common material and common simultaneously
Technique makes, and core can be completed by manual or simple and mechanical device with stud combination assembling, the making of component
Cost and installation cost are low.

Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
As shown in Figure 1 to 4, this component includes stud 10 and core 20；Stud 10 includes support body 12, support
The top of body 12 is provided with fastener 11, and support body 12 is provided with clamping circular arc 13, and the end of clamping circular arc is arranged
Having opposing parallel two clamping part 14, clamping part 14 has free end 15；Core 20 includes core body 21,
Arranging multiple core groove 22 on the core 21, described core groove 22 is provided with seam 23, seam 23 1 transverse plane
Core groove 22 external arc joint is provided with arc-shaped projection 25, the described center of circle of protruding 25 to protruding (25)
Arcuate midway point formed ray and seam 23 plane between angle be 40 °～50 °, the width of seam 23
It is smaller in size than the width dimensions between two described clamping parts 14.
Preferably a kind of embodiment of this component is that the width of core groove 22 is not less than the thickness of described stud 10,
So stud 10 can be completely embedded in core, and the existence of stud 10 does not interferes with the dimensional accuracy of cast.
Preferably a kind of embodiment of this component is only to be provided with transition between core groove 22 external arc and protruding 25
Mouth 24, realizes seamlessly transitting between core groove 22 external arc and protruding 25, Ke Yiyou by transition seam 24
Effect avoids the stress of joint between core groove 22 external arc and protruding 25 to concentrate.
This component assembles as follows:
Stud 10 snaps in core 20 seam 23 position according to the direction of arrow shown in Fig. 5, it is ensured that stud 10
Inner arc surface 13 contacts the position relationship snapping in rear stud 10 with core 20 with core seam 23 exterior arc surface
As shown in Figure 6；
Core 20 maintains static, and by stud 10 counterclockwise half-twist, the projection on core 20 is blocked
The clamping part 14 of stud, after rotation, the position relationship between stud 10 and core 20 is as shown in Figure 1.
Above-mentioned embodiment is used for illustrating the present invention rather than limiting the invention, in the present invention
Spirit and scope of the claims in, any modifications and changes that the present invention is made, both fall within this
The protection domain of invention.
