Description
Technical field
The present invention relates to cast casting ancillary equipment and techniques, are specifically related to casting and play mold technique and tooling, for big
Type casting molding.
Background technique
The heavy castings such as marine diesel cylinder body, for height generally at 1-2.5 meters, die model side skin living is larger, and it is tired to play loose piece
Difficulty, and uneven, sand mold easy to damage when being removed outside skin living；Since heavy castings skin die model big, living is soft, normal operating is grasped uneven
Weighing apparatus part power-assisted can cause skin problem on deformation living greatly in molding, cause rate of wasted casting product high, reduce production efficiency.
Summary of the invention
In view of defect existing for above-mentioned technology, the object of the present invention is to provide a kind of casting to play mold technique and tooling, not only
Labour can be saved, and can be realized the multiple spot molding in heavy castings smoothly by skin ejection living, will appreciate that balance,
It avoids part power-assisted when molding from causing skin problem on deformation living greatly, improves casting quality, improve production efficiency.
To achieve the goals above, the technical scheme adopted by the invention is that: casting rise mold technique, the specific steps are as follows:
(1) several die model units of arrangement in sandbox carry out molding sand between inner wall of sand box and several die model units and cast to form sand
Type；When forming above-mentioned sand mold, be in contact in sand mold with several die model inner walls the pre-buried several refractory brick in position；
(2) position corresponding with pre-buried refractory brick is reserved with through-hole in die model, and die craft equipment has been arranged in through-hole；Described
Die craft equipment be it is spiral, formed by spirally playing die craft equipment and refractory brick and jack up point, will under the turning effort for playing die craft equipment
Die model ejection；
(3) die model after ejection is sling vertically by being fixed at the hoisting ring at both ends at the top of die model, die model is removed, it is complete
It works at molding.
Planar alignment is arranged between several die model units as described in step (1)；
Round, rectangular or other irregular shapes of through-hole described in the step (2)；
Multiple molding points are respectively adopted on each die model unit, each molding point is living by entire die model according to sequencing
Skin carries out molding；
Preferably, the molding point in each die model is set as 5；
It is furthermore preferred that 5 molding points use each 1 point of die model quadrangle with quadrangle center for 1 dot pattern；
Die craft equipment is played using above-mentioned technique, comprising: nut, screw rod, the nut center are equipped with through-hole, screw rod outer surface
Equipped with screw thread, the internal screw thread matched with the screw thread of screw surface is equipped in through-hole, screw spiral is set in the through-hole of nut,
Screw rod one end is equipped with pull ring；
The nut section is T stage shape；
The nut ring sets circumferential position and is equipped with 3 threaded securing bores, is respectively equipped with bolt in 3 threaded securing bores.
Casting rises in mold technique in step (1)-(3), and the screw rod risen in die craft equipment passes through die model,；Screw rod one end withstands on resistance to
The pull ring on firebrick surface, the screw rod other end is located at outside die model, and die model is fixed together by 3 bolts and nuts, passes through rotation
Turn pull ring, nut retreats, and makes nut that die model be driven to retreat together, and then die model is ejected.
Further, die model outer wall surface can also be arranged in the die craft equipment, in position corresponding with die lifter
Reserved through hole is not necessarily in the die model set；The nut of die lifter is bonded with die model outer wall, then passes through 3 spiral shells on nut circumference
Line fixation hole will play die craft equipment and be fixed with die model.
Beneficial effect by adopting the above technical scheme is:, will skin living by screw rod rotation using pre-buried refractory brick in sand mold
Smoothly take out；Modulus method is played using multiple spot, is overcome since casting is big, skin die model living is soft, normally grasps unbalanced defect, avoids
Part power-assisted causes greatly skin problem on deformation living when molding, and sand mold and skin living do not damage, improve casting quality, improve production efficiency.

Fig. 1 is casting molding process structure schematic diagram of the present invention.
Fig. 2 is molding tool structure figure.
In figure, 1, sand mold, 2, die model unit, 3, refractory brick, 4, die craft equipment, 5, hoisting ring.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawing.As shown in Figure 1, marine diesel cylinder block casting, highly exists
1-2.5 rice.Play mold technique, the specific steps are as follows:
(1) several die model units 2 of arrangement in sandbox carry out molding sand between inner wall of sand box and several die model units 2 and cast to be formed
Sand mold 1；When forming above-mentioned sand mold 1, be in contact in sand mold 1 with several 2 inner walls of die model the pre-buried several refractory brick 3 in position；
(2) position corresponding with pre-buried refractory brick 3 is reserved with through-hole in die model 2, and die craft equipment 4 has been arranged in through-hole；Institute
Stated die craft equipment be it is spiral, formed by spirally playing die craft equipment 4 and refractory brick 3 and jack up point, made in the rotation for playing die craft equipment 4
