Abstract
The utility model relates to a wet sand mold molding machine which is mainly characterized in that the wet sand mold molding machine is improved on the basis of the existing wet mold molding machine. Replaceable filling materials capable of flowing and incapable of being compressed are arranged at the bottom of an upper pressing plate of the wet sand mold molding machine. With the adoption of the technical scheme, after the pressing plate of a pressing head of the molding machine is in contact with molding sand, the molding sand can achieve uniform pressure along with the flowing pressure of a rubber block under the action of low pressure in the molding process, thereby achieving uniform strength and preventing the situation that in order to achieve the strength of a cavity, the pressure of a traditional molding machine is improved at random to cause bad sand mold breathability. Compared with the prior art, the wet sand mold molding machine has uniform strength, good breathability and good collapsibility and can greatly improve the quality of sand molds and the qualification rate of castings.
Description
Technical field
The utility model belongs to the Casting Equipment technical field, is specifically related to a kind of greensand mold moulding machine.
Background technology
At present, the moulding machine that casting industry uses, in order to obtain different mold shape, the enough intensity that need use of the bigger model of size height great disparity particularly, the artificial intensified pressure of having to has brought the defective of sand mold gas permeability, collapsibility difference again; To this situation, the multiple contact moulding machine makes moderate progress, and runs into when mould is high to be put but contact occurs, can not press down, and can not reach uniform strength equally; Though the air bag pressure head can satisfy the uniformity of sand mold, but limitation is strong random poor, can not change the size dimension of sand mold arbitrarily, and the complex structure durability is poor.
Summary of the invention
The inventor is in the process of being engaged in the Casting Equipment manufacturing; Find the problems referred to above and defective that existing greensand mold moulding machine exists; In order to overcome the problems referred to above and defective; The purpose of the utility model provides a kind of greensand mold moulding machine, makes molding sand be issued to uniform thickness in flowing pressure, has ensured the uniform consolidation intensity of sand mold, has improved sand-mould quality and casting qualified rate.
For achieving the above object, the technical scheme that the utility model is taked is in addition improved on the basis of original greensand mold moulding machine, and the pressing plate bottom on greensand mold moulding machine pressure head is provided with removable ability incoercible packing material that flows.
The mobile incoercible packing material of said ability includes block rubber.
Because the utility model taked technique scheme, in modeling process, the pressing plate of moulding machine pressure head is with after molding sand contacts; Under the effect of high pressure not; Make sand mold reach uniform pressure, thereby make sand mold reach uniform intensity along with the flowing pressure of block rubber; Having avoided the traditional design machine is to reach die cavity intensity and the pressure that improves moulding machine wantonly, causes the sand mold gas permeability poor.Compared with prior art, the utlity model has intensity evenly, good permeability and the good advantage of collapsibility, can improve sand-mould quality and casting qualified rate greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the architectural feature of the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1. pressure head, 2. packing material, 3. sand frame, 4. sandbox, 5. molding sand, 6. model, 7. travelling carriage, 8. oil cylinder.
The specific embodiment
Referring to accompanying drawing; The said greensand mold moulding machine of the utility model comprises pressure head 1, sand frame 3, sandbox 4, molding sand 5, travelling carriage 7 and oil cylinder 8; Said pressure head 1 includes pressing plate; Be provided with the mobile incoercible packing material 2 of removable ability in said pressing plate bottom; Incoercible packing material 2 that can flow produces mobile under pressure with the mould difformity, make molding sand be issued to uniform thickness in flowing pressure, ensured the uniform consolidation intensity of sand mold, has improved sand-mould quality and casting qualified rate.
The mobile incoercible packing material of said ability includes block rubber.
Embodiment recited above describes the utility model preferred implementation; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design philosophy; The replacement of the various equivalent features that those skilled in the art make the utility model technical scheme all should belong to the protection domain of the utility model.
Claims (2)
1. a greensand mold moulding machine comprises pressure head, sand frame, sandbox, molding sand, travelling carriage and oil cylinder, and said pressure head includes pressing plate, it is characterized in that being provided with the mobile incoercible packing material of removable ability in said pressing plate bottom.
