Description
Technical field
The present invention relates to a kind of universal sand ejection board, relate generally to a kind of the universal of casting chaplet box coremaking equipment and penetrate
Sand plate.
Background technology
Traditional shell core coremaking equipment, its sand bucket and sand ejection board are isolating construction, sand ejection board as mould a part,
It is fixed on by 20 M8 hexagon socket head cap screws on sand bucket, needs to be replaced with the Special ejection sand supporting with corresponding mould during mold changing coremaking
Following problem is primarily present in plate, its whole production process：1st, shooting pressure is unadjustable during coremaking, influences coremaking matter
Amount；2nd, every pair of mould is required for supporting special sand ejection board, wastes Mold Making time and expense；3rd, changing sand ejection board needs clearly
Precoated sand in empty sand bucket, dismantles old sand ejection board, more renews sand ejection board, whole process wastes time and energy, and Renewal process can not
Avoid that precoated sand can be spilt, cause the waste of sand and the pollution of environment；4th, miscellaneous special sand ejection board is to mold management
Make troubles.
The content of the invention
It is an object of the invention to overcome, above-mentioned not enough there is provided a kind of shooting pressure is adjustable, it is adaptable to different moulds it is logical
Use type sand ejection board.
The object of the present invention is achieved like this：
A kind of universal sand ejection board, it is characterised in that it includes postive stop baffle, support and sand ejection board successively from top to bottom
Mainboard, postive stop baffle and support have gap, and support and sand ejection board mainboard have gap, and the edge of the sand ejection board mainboard is provided with one
Enclose on multiple sand-spraying holes that array arrangement is provided with link bolt hole, the sand ejection board mainboard, the support and be provided with position
The screw corresponding with the sand-spraying hole on sand ejection board mainboard, the sand-spraying hole inward turning is equipped with closing plug, the screw of the support
Inside it is provided with regulation plug.
It is provided with below the sand ejection board mainboard and position is provided with sealing plate, sealing plate with penetrating sand on sand ejection board mainboard
The corresponding hole in hole.
Sealing plate uses high-temperature resistant rubber.
Sealing plate is glued on sand ejection board mainboard using high-temperature resistant rubber.
Support and sand ejection board mainboard gap are 5 ~ 8mm.
Sand-spraying hole is preferably that 3 rows 18 are arranged, and sand-spraying hole horizontal spacing is 25mm, and sand-spraying hole longitudinal pitch is 30mm.
Compared with prior art, the beneficial effects of the invention are as follows：
Sand ejection board increase regulation plug of the present invention, by controlling to adjust the closure distance of plug, so as to control on sand-spraying hole
The openings of sizes of side, reaches the purpose of regulation coremaking shooting pressure, drastically increases core quality；Sand ejection board mainboard sand-spraying hole
Multiple general sand-spraying holes are changed to by special sand-spraying hole, only need to open the sand-spraying hole of needs during mold changing coremaking according to demand i.e.
Can, it is not necessary to change sand ejection board, coremaking efficiency is drastically increased, and open time and cost can be saved；Therefore, this hair
Bright universal sand ejection board has adjustable shooting pressure, improves coremaking quality and production efficiency, saves open time and cost
Advantage.
Brief description of the drawings
Fig. 1 is top view of the invention.
Fig. 2 is sectional view of the invention.
Wherein：
