Shape face, when specific works, smooth motor 43 drives flat disc 44 to rotate, and the smooth connecting rod 45 on flat disc 44 is with action-oriented
Sliding block 46 does eccentric motion, has achieved the effect that vibration, guide plate 47 moves up and down together with guiding contact plate 48, so that smooth
Plate 49 moves up and down, smooth electronic 42 side-to-side movement of sliding block, so that formation plate 49 is by the sandy soil even uniform on bottom plate 1, and bullet
Spring 411 makes the dynamics of formation plate 49 moderate, so that sand mold meets the requirement of casting metals solution.
When work, after the middle part of bottom plate 1 piles with the sandy soil of production molding sand, loose motor 29 is started to work, loose motor
29 drive movable plate 24 to do eccentric motion by eccentric ratio 211, and the loose thorn 22 on movable plate 24 is due to loose plate 21
The hole of interior setting limits, and loose thorn 22 can only do side-to-side movement, so that under the action of the sandy soil of bottom plate 1 are in loose thorn 22
To being sufficiently stirred, the gap between sandy soil will be also filled, and after being sufficiently stirred, loose motor 29 stops working, auxiliary electricity
Movable slider 212 will be mobile with parallel-plate 26, and until the right end 22 of loose thorn leaves the horizontal position of switch boards 23, switching is electronic
Sliding block 28 drives switching cylinder 215 mobile, so that the middle part that the plugging block 214 in switch boards 23 is located at loose plate 21 is uniformly distributed
Hole right above, switching cylinder 215 plugging block 214 is pushed in the hole being arranged in loose plate 21, will be in loose plate 21
The hole of setting is blocked, and prevents from causing destruction to the shape of molding sand when production molding sand, so that molding sand is imperfect, loose plate sliding block
25 make loose 21 rear and front end of plate can with slid inward, filling block 213 on loose plate sliding block 25, filling block 213 with it is loose
Plate 21 is in close contact, and can prevent the leakage of sandy soil, and after sand mold is sufficiently stirred, loose plate 21 is inwardly squeezed, thus
The suitable sand mold of density is made, sizing motor 32 first is started to work, and sizing motor 32 drives the auxiliary in sizing shaft 33 to push away
Plate 35 is got rid of bar 36 under the promotion of auxiliary push plate 35 by what hinge was connected with sizing shaft 33, is got rid of due to the effect of gravity
With shaft 33 of being formed for the center of circle, the length to get rid of bar 36 moves in a circle bar 36 as radius, gets rid of hammer 37 and is getting rid of bar 36 positioned at minimum
Bump against when point with loose plate 21, under the shock for getting rid of hammer 37, loose plate 21 does not inwardly compress sandy soil, after shock, sizing
Motor 32 inverts, and auxiliary push plate 35 is in contact with bar 36 is got rid of, and assists push plate 35 that will get rid of bar 36 and back circle, when getting rid of bar 36
After being rotated by 90 °, can be tilted to protective plate 34, the arcwall face of protective plate 34 be bonded with bar 36 is got rid of, the loose needs of plate 21 again to
When interior compression, above-mentioned movement is repeated, smooth motor 43 drives flat disc 44 to rotate, 45 band of smooth connecting rod on flat disc 44
Action-oriented sliding block 46 does eccentric motion, has achieved the effect that vibration, and guide plate 47 moves up and down together with guiding contact plate 48, makes
It obtains formation plate 49 to move up and down, smooth electronic 42 side-to-side movement of sliding block, so that formation plate 49 is smooth by the sandy soil on bottom plate 1
It is even, and spring 411 makes the dynamics of formation plate 49 moderate, so that sand mold meets the requirement of casting metals solution, realizes one
The function of changing production molding sand, solve sandy soil inside the molding sand of existing manual manufacture cannot stir evenly, artificial smooth upper layer
Sandy soil poor flatness, the problems such as container tightness difference when cannot control well to the gas porosity of sand mold, make sand mold, reach
