Description
Technical field
The utility model relates to Casting Equipment field, specially a kind of lost foam casting sandbox.
Background technique
Casting is the metal forming object obtained with various casting methods, i.e., the liquid metal smelted, with casting, pressure
Penetrate, suck or other casting methods inject in preprepared casting mold, it is cooling after after the following process means such as polishing, gained
That arrives has certain shapes, the object of size and performance.Casting applicating history is long.Ancient times people are made with casting and some lives
Apparatus.Modern age, casting are mainly used as the blank of element part, some precision castings can also be directly used as the components of machine.
General casting all passes through sandbox casting and forming, and common sandbox is open type, is cooled and shaped after pouring metal melt, casts certainly in this way
The components interior density made is not uniform enough, be easy to appear stomata, it is loose the defects of, the resistance to pressure of casting is poor, and total quality is not
Enough height.
Currently, the cast member better quality in order to guarantee production, mostly uses founding casing with vacuum technology to be cast, i.e.,
Mold is put into sandbox, the dry sand of adhesive-free is added to cover, layer of plastic film is covered again on dry sand and is sealed, pour
So that the dry sand in sandbox is generated negative pressure using the principle of suction afterwards, make dry sand consolidation, extrusion die, which reaches, improves casting quality
A kind of technology.Plastic film directly overlays on sandbox in the prior art, it cannot be guaranteed that sealing effect, while using very not
Just.
In addition, the working chamber size of existing sandbox cannot change, therefore no matter then workpiece size, is required to equivalent
Molding sand causes the waste of molding sand.
Utility model content
The purpose of this utility model provides a kind of lost foam casting sandbox, can effectively solve asking in background technique
Topic.
Realizing the technical solution of above-mentioned purpose is: lost foam casting sandbox, including rack, is provided with upper end in rack and opens
Mouthful rectangular sandbox cabinet, be provided with liftable partition in sandbox cabinet, sandbox cabinet is divided into mutually indepedent, simultaneously by partition
In upper and lower arrangement mold cavities and vacuum chamber, vacuum chamber is connected with negative pressure sucking air pipe, and the partition is sand container orifice plate, the partition
Upper plane be equipped with sieve；It is characterized by: being equipped with the elevating mechanism of driving partition lifting, the elevator in the rack
Structure includes spaced multiple turbine and worm transmission cases, and turbine and worm transmission case includes cabinet, is equipped in cabinet and mutually nibbles
The turbine of conjunction, worm screw, turbine, worm screw both ends pass through bearing and be installed in cabinet, be connected as one by connecting rod between worm screw
Body, is also equipped with the servo motor of driving worm screw rotation in rack, and turbine is coaxially installed with screw rod respectively, the upper end end of screw rod to
On across sandbox cabinet and be connected with lifter plate, lifter plate is connect with partition.
The utility model has the beneficial effects that
The utility model can be such that mold cavities can adapt to different big according to the size of the big minor adjustment mold cavities of casting
The casting of light casting, while the molding sand dosage for adjusting different casting improves economic benefit to realize the saving of molding sand.
The size Principles of Regulation of mold cavities: worm screw rotation is driven by rotation handwheel, worm screw drives turbine rotation, turbine
Drive screw rod rotation, screw rod lifting belt dynamic dividing plate height adjustment, to realize the big minor adjustment of mold cavities.
Further, screw rod sealing is provided with described in the sealing effect for guarantee vacuum chamber between screw rod and sandbox cabinet
Circle.
Further, the surrounding of the upper port of the sandbox cabinet is provided with the first magnet, the inside of the first magnet and outer
Side is respectively arranged with rectangular retaining ring, and retaining ring magnet protruding upward forms seal groove, is equipped on the sandbox cabinet close
Capping, the sealing cover includes square frame, and plastic foil is equipped on square frame, be provided on the inside of the square frame with
The second attracted magnet of first magnet, second magnet are equipped in the seal groove simultaneously.
The plastic foil of the utility model is mounted on square frame, and directly lid closes the upper port in sandbox cabinet when use,
And the first resealing is realized by the second magnet and the cooperation of the first magnet, while the second magnet is equipped with and realizes in seal groove
Second resealing has the advantages that easy to use, sealing effect is good.
