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.
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, spring is additionally provided between described upper connecting rod and lower connecting tube, is also connected between described upper blade and lower blade
Auxiliary wire drawing is connected to, due to being not in the entirely appropriate position of angle during use, auxiliary wire drawing can be played preferably fixed
Type is acted on.
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：Simplify the casting technique difficulty of product, reduce the complex process class of product,
Product size precision and the accuracy of form and position are improved, it is more superior particularly with the complicated casing in inner chamber and housing class product casting
Property；Solve the folding core of such product, float core the problems such as, improve the yield rate of such product；Improve production efficiency,
Production cost is reduced, the competitiveness of product in market is improved.
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 auxiliary wire drawings 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
It is also associated with aiding in wire drawing 6 between 3 and lower blade 2, due to being not in the entirely appropriate position of angle during use, auxiliary
Wire drawing 6 can play more preferable styling, and described upper blade 3 and the thickness of lower blade 2 are 0.4-0.5mm, described spring
For helical spring.
The beneficial effects of the invention are as follows：The casting technique difficulty for simplifying product, the complex process shelves for reducing product
It is secondary, product size precision and the accuracy of form and position are improved, it is more excellent particularly with the complicated casing in inner chamber and housing class product casting
More property；Solve the folding core of such product, float core the problems such as, improve the yield rate of such product；Improve production
Efficiency, production cost is reduced, improve the competitiveness of product in market.
