It is wider, the labor intensity of operator is substantially reduced, improves production efficiency.
As shown in Fig. 2 setting sand block plate 20 on installing plate 3, sand block plate 20 is located at below the hopper hole of the bottom of sandbox 4；Gear
Sand block plate hole 201, column spinner 202, spring stack 203 and sand block bucket post 204 are provided with sand plate 20.Sand block plate 20 is located at hopper hole
Below, when penetrating sand hopper 5 and being moved at sand block plate 20, the sand block bucket post 204 that sand hopper drives the sand block plate is penetrated, around column spinner 202
Rotation, when three sand hopper hole, sand block plate hole 201 and hopper hole hole coaxial lines is penetrated, the sand material inside hopper is inside hopper
Incident sand hopper is entered by sand block plate, sand hopper charging sand is penetrated in completion.When penetrating sand hopper and filling it up with material sand, penetrate sand hopper and go to moving at mould
Sand work is penetrated in completion, and at this moment sand block plate follows the mobile beginning for penetrating sand hopper around rotation under spring force in spring stack 203
Post 202 rotates, and the sand block plate hole 201 of sand block plate and hopper is entered sand hole not coaxial line, sand block plate just blocks expects inside hopper
Sand flow comes out.The sand block plate 20 is simple in construction, and function is extremely important, effectively solves the supply of hopper material sand and penetrates asking for sand hopper
Topic.
Valve body controlling organization is provided with as shown in figure 3, penetrating on sand hopper, valve body controlling organization includes valve block 30, valve block 30 1
Apertured 301 is held, the other end sets the bellmouth of control sand material disengaging, and the top in hole 301 sets cylinder or hydraulic cylinder, valve block 30 1
Side sets air admission hole 302.Valve block 30 is to control the leakage of sand shot bucket husky in a vertical core shooter of the precoated sand applied to casting industry
Valve block, surface can be cylinder or oil cylinder, and by using the flexible principle of piston, taper is set in the lower section of mechanism
Hole control sand disengaging.Air admission hole 302 is set in mechanism side openings, when bellmouth is opened, air admission hole 302 inflates entrance
Mechanism, the sand of sand shot bucket is squeezed into mould；When taper bore closure, the hole of air inlet 302 stops inflating to mechanism, and sand stops
Only enter sand shot bucket.
As Figure 4-Figure 6, penetrate on sand hopper 5 and be provided with air shut-off valve body mechanism, air shut-off valve body mechanism includes upper
End cap 401, valve body 402, bottom end cover 403 and sealing gasket 404.Air inlet 406 is set on upper end cover 401, set on bottom end cover 403
Gas outlet, valve body 402 are arranged between upper end cover 401 and bottom end cover 403, are set and air inlet 406, gas outlet on valve body 402
The air duct 405 communicated；Sealing gasket 404 is arranged on upper end cover 401.Upper and lower end cover structure is identical, and upper end cover is air inlet,
Bottom end cover is gas outlet, when having air to enter mechanism from air inlet, valve inner air-passage opening, is stopped when there is air
When only entering mechanism by air inlet, valve inner air duct is closed.
As shown in fig. 7, shaft sleeve sealing device includes axle sleeve 702 and shaft-cup 701, shaft-cup 701 is arranged on the one end of axle sleeve 702,
Hydraulic fluid interface is set in axle sleeve 702.Shaft sleeve sealing device is applied to the dress that the coated sand core shooting machine moving platen of casting industry moves
Put, the shaft sleeve sealing device is not only only capable of preventing sand from entering between moving platen and slide-bar 6, prevents slide-bar 6 to be scratched, causes to move
The generation of the not smooth phenomenon of template movement, and hydraulic oil seal is used in the shaft sleeve sealing device, between moving platen and slide-bar 6
Oil film is formed, while making the feed rod avoid being scratched, makes moving platen movement more smooth, reduces the resistance of moving platen oil cylinder, drop
The power of low pumping plant, while reduce energy consumption.The shaft sleeve sealing device reduces relative to other types axle sleeve, overall dimension, adapts to
Property it is wider, be not only applicable to relatively thin axle, for the thick axle of major diameter be even more be widely used.
As shown in figure 8, the top of sandbox 4 sets upper sand device, the upper sand device includes cylinder 801, and the one end of cylinder 801 is set
Put air switch controller 802 and for controlling the check valve 803 into sand, the other end sets sand export 804, is spaced apart switch control
The air switch of device 802 connects.Upper sand device realizes the Automated condtrol supply for covering sand, not only in the core shooter course of work
Shorten the production cycle, also reduce manual labor, and it is more efficient and convenient.The design at check valve by controlling into sand, when need
When upper sand, the sand in the sand hopper above check valve is fallen into cylinder 801 by Action of Gravity Field, and air switch is opened, by cylinder
Sand gets sand export in 801, and sand function in realization, structure is convenient and simple, reduces the production time, shortens the production cycle, improves work
Make efficiency.
As shown in Figure 9, Figure 10, penetrating sand hopper 5 is included into sand cylinder 902 and sand warehouse 903, enters sand cylinder 902 and is arranged in sand warehouse 903
Side, is connected with sand warehouse 903；Enter the upper end of sand cylinder 902 and sand inlet 901 is set, the bottom of sand warehouse 903 sets sand export 904.Sand cylinder is circle
Tubular；Sand warehouse section is wider with entering one end that sand cylinder is connected to be trapezoidal, narrower at sand export.
In core shooter application field, sand shot bucket 5 is a part essential in the core shooter course of work, and the design breaks
Traditional sand shot bucket pattern, the innovative design from structure, reduce the size of sand shot plate, from the appearance more specification, from performance
Upper raising sand export goes out sand drift amount, makes sand shot core fuller, improves finished workpart rate, improves production efficiency.
As shown in figure 11, walking mechanism includes feed rod slideway 1101, walking sliding sleeve 1102, contiguous block 1103 and walking power
Device 1104, feed rod slideway 1101 are arranged on the support below installing plate, and walking sliding sleeve 1102 is sleeved on feed rod slideway 1101
On, walking sliding sleeve 1102, which is fastenedly connected, is penetrating sand hopper both sides.Sand hopper is penetrated as two, each penetrates one contiguous block of setting on sand hopper
1103, contiguous block 1103 is two altogether, and each contiguous block 1103 fills 1104 and put and is connected with a power of walking.Penetrating sand hopper 5 can edge
Feed rod slideway 1101 moves left and right, when penetrating sand hopper 5 and being moved to 4 lower section of sandbox, when penetrating sand hopper hole, sand block plate hole 201 and hopper
When the three hole coaxial lines in hole, the sand material inside hopper enters incident sand hopper inside hopper by sand block plate, and completion is penetrated sand hopper and added
Expect sand.When penetrating sand hopper 5 and moving right to below high pressure air jet nozzles, high pressure air jet nozzles spray pressure-air, and material sand is from penetrating sand
The dies cavity that the sand export of bucket 5 enters on mould bases.In the present embodiment, walking power set are cylinder/hydraulic cylinder.In core shooter
In the course of work, the mobile traditional approach of sand shot bucket is that traditional wheeled slideway is changed into light by wheeled slip, the design
Thick stick slideway, slideway is changed to outside from the inside of U-type groove in structure, reduces the limitation of U-type groove inside dimension, improves storage sand bucket
Store up sand amount.From performance, the frictional resistance of polished rod slideway is more many than the wheeled reduction slided into, and controllability is more convenient.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
