Description
Technical field
The present invention relates to a kind of fixed core a kind of spring stud, category 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
Shape, the size of the shape of position, die cavity in casting, the wall thickness selection stud of casting.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, and each stud is also needed for walk measures it
Highly, workload is quite big, and turning into influences moulding, a prominent weak link of lower core efficiency.Therefore, it is a kind of to be badly in need of innovation
A kind of spring stud of widely used fixation core.
Stud on the market is mostly " work " font at present, is usually present the problem of molten steel can not melt stud completely.
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 are set in lower connecting tube,
And be fitted close, spring is additionally provided between described upper connecting rod and lower connecting tube, described upper blade is provided with pore.
Further, the thickness of described upper blade and lower blade is 0.4-0.5mm.
Further, described spring is helical spring.
Further, described pore aperture is in 1-5mm.
The beneficial effects of the invention are as follows：Solve the problems, such as that molten steel can not melt stud completely, simplify the casting of product
Technology difficulty, the complex process class for reducing product, improve product size precision and the accuracy of form and position, are answered particularly with inner chamber
Miscellaneous casing and housing class product casting has more superiority；Solve the folding core of such product, float core the problems such as, improve such
The yield rate of 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, pore 7 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 the connector of the upper blade 3 of connection 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 upper blade 3 of described upper connecting rod 5 connection, the lower blade 2 of described lower connecting tube 4 connection, described upper connecting rod 5 are 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
3 and the thickness of lower blade 2 be 0.4-0.5mm, described upper blade 3 is provided with pore 6, and described pore aperture is in 1-5mm.
The beneficial effects of the invention are as follows：Solve the problems, such as that molten steel can not melt stud completely, simplify the casting of product
Technology difficulty, the complex process class for reducing product, improve product size precision and the accuracy of form and position, are answered particularly with inner chamber
Miscellaneous casing and housing class product casting has more superiority；Solve the folding core of such product, float core the problems such as, improve such
The yield rate of product；Improve production efficiency, reduce production cost, improve the competitiveness of product in market.
