Description
Technical field
The present invention relates to a kind of fixed core with a kind of spring stud, belong to casting technology field.
Background technology
At present, the use of the supporter of special shape is that stud is a kind of logical to core progress Auxiliary support in foundry engieering
The practice.The shape of stud is varied, and plane, circular arc, U-shaped etc., size is different in size, be according to stud
The shape of position, die cavity in casting, the wall thickness of casting select shape, the size of stud.But for group core is more, compartment is more,
Disconnected chamber, the complicated cavity product of disconnected outstanding core and wall thickness dimension, the accuracy of form and position require strict product, it is necessary to design and produce perhaps
The stud that Multiple Shape is different, size is different, some stud height great disparities are larger, needed for each stud also measures it with walk
Highly, workload is quite big, a prominent weak link as influence moulding, lower core efficiency.Therefore, it is badly in need of innovation a kind of
Widely used fixation core is with a kind of spring stud.
At present, occur in that and occur in that a kind of is in the stud of " work " font on the market, for supporting what is formed in sandbox
Cavity.Although prevent damage target part model on have very big improvement, due to staff imprudence or the external world
Slight impact, the stud is understood run-off the straight or toppled over, and supports insecure, equally will also result in the damage of target part model.
The content of the invention
The purpose of the present invention is exactly to overcome disadvantages described above there is provided a kind of spring stud
The technical scheme is that, a kind of spring stud, including upper blade and lower blade, and the upper blade of connection and lower blade
Connector, it is characterised in that：Described connector includes upper connecting rod and lower connecting tube, and described lower connecting tube is metal tube,
The described upper blade of upper connecting rod connection, the lower blade of described lower connecting tube connection, described upper connecting rod is set in lower connecting tube,
And be fitted close, the top in spring, described upper blade is additionally provided between described upper connecting rod and lower connecting tube provided with extension
Block.
Further, the thickness of described upper blade and lower blade is 0.4-0.5mm.
Further, described spring is helical spring.
The beneficial effects of the invention are as follows：The present invention specially adds on existing stud basis and is arranged at stretching for end
Go out end, due to the presence of external part, when stud is supported, external part is directly protruding into the sand body in sandbox, make the present invention just
Firmly it is fixed on as nail in sand body, also will not be because of toppling over for stud even if there is the slight impact in the external world
So that the target part model damage formed.Meanwhile, the material of the stud and the material of target part are identicals, when curable
Material carry out in the cavity that is formed of sandbox, solidified based on stud, quickly form target part；Simplify product
Casting technique difficulty, the complex process class for reducing product, improve product size precision and the accuracy of form and position, particularly with interior
The complicated casing of chamber and housing class product casting have more superiority；Solve the folding core of such product, float core the problems such as, improve
The yield rate of such product；Improve production efficiency, reduce production cost, improve the competitiveness of product in market.
Brief description of the drawings
Fig. 1 is the structure sectional view of the present invention.
In figure, 2 times blade, blade, 4 times connecting tubes, 5 upper connecting rods, 6 springs, 7 extension blocks on 3.
Embodiment
Embodiment below in conjunction with the accompanying drawings, the present invention is further described.As illustrated, a kind of spring stud, including upper support
Piece 3 and lower blade 2, and connect the connector of upper blade 3 and lower blade 2, upper blade 3 and the lower material therefor of blade 2 and casting
Material is identical, the fusing point of a little higher than casting metal of its fusing point, to ensure that it has enough intensity before casting does not solidify completely
Support core, while fused well with casting in process of setting, surface is clean, oil-free, it is rustless, without aqueous vapor, it is preferably zinc-plated
Or it is tin plating, strict pickling is wanted before plating.Described connector includes upper connecting rod 5 and lower connecting tube 4, and described lower connecting tube 4 is
Metal tube, the described upper blade 3 of the connection of upper connecting rod 5, the lower blade 2 of the described connection of lower connecting tube 4, described upper connecting rod 5 is arranged
In lower connecting tube 4, and it is fitted close, spring 6, described upper blade is additionally provided between described upper connecting rod 5 and lower connecting tube 4
Top on 3 is provided with extension block 7, and described upper blade 3 and the thickness of lower blade 2 are 0.4-0.5mm.
The beneficial effects of the invention are as follows：The present invention specially adds on existing stud basis and is arranged at stretching for end
Go out end, due to the presence of external part, when stud is supported, external part is directly protruding into the sand body in sandbox, make the present invention just
Firmly it is fixed on as nail in sand body, also will not be because of toppling over for stud even if there is the slight impact in the external world
So that the target part model damage formed.Meanwhile, the material of the stud and the material of target part are identicals, when curable
Material carry out in the cavity that is formed of sandbox, solidified based on stud, quickly form target part；Simplify product
Casting technique difficulty, the complex process class for reducing product, improve product size precision and the accuracy of form and position, particularly with interior
The complicated casing of chamber and housing class product casting have more superiority；Solve the folding core of such product, float core the problems such as, improve
The yield rate of such product；Improve production efficiency, reduce production cost, improve the competitiveness of product in market.
