Description
Technical field
The utility model is related to foundary industry field, specially a kind of lost foam casting sandbox being convenient to clean.
Background technology
Casting is the metal forming object obtained with various casting methods, i.e., the liquid metal smelted, with cast, 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 definite shape, 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 parts of machine.
For general casting all by sandbox casting and forming, common sandbox is open type, is cooled and shaped after pouring metal melt, casts so certainly
The components interior density made is not uniform enough, be susceptible to stomata, it is loose the defects of, the resistance to pressure of casting is poor, and total quality is not
Enough height.
Currently, in order to ensure the cast member better quality of production, mostly uses founding casing with vacuum technology and 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.During existing founding casing with vacuum in order to ensure plastic foil complete and foundry security against fire,
It needs to be prepared in advance plastic foil in the place far from foundry, uses is fetched from other places again when needing overlay film, in this way modeling
Taking for material film is very inconvenient, also increases the time cost of production.
In addition, cleaning sandbox is inconvenient after existing sandbox pours, sandbox tipping is needed to turn 180 °, it could be by the type in sandbox
Sand and casting cleaning come out, time-consuming and laborious, and labor intensity is big, and blanking is inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of lost foam casting sandbox being convenient to clean, and can effectively solve background skill
The problems in art.
Realizing the technical solution of above-mentioned purpose is：The lost foam casting sandbox being convenient to clean, it is characterised in that：Including machine
Frame is provided with the sandbox babinet of upper end opening in rack, and the side on sandbox babinet top is connected with rotating cylinder, modeling is wound on rotating cylinder
Expect film；
Sandbox babinet includes the frame that bottom plate and four pieces of sidings surround, and it is convex that the surrounding in frame lower port is provided with support
Edge, bottom plate are fitted on support lugn upwards, and bottom plate is provided with sealing ring, one end of bottom plate and the wall of corresponding end with support lugn
Plate is hinged, and the bottom of bottom plate is provided with the cylinder for switch baseplate, and the output end of cylinder is hinged on the bottom of bottom plate, cylinder
Tail end is hinged with rack.
Further, the double-layer structure that the siding is made of inside panel and exterior panel is provided in siding closed
Cavity is evenly equipped on the inside panel in sandbox babinet and vacuumizes hole, sand control screens, four pieces of walls are covered on the inside panel of sandbox babinet
The true tracheae of pumping for the connection that is interconnected is connected separately on plate.
Further, the width of the plastic foil be more than sandbox babinet upper port width, the free end of plastic foil and
Along being evenly equipped with snap ring respectively, other three sides that rotating cylinder is not arranged for sandbox babinet are respectively arranged with and coordinate with snap ring for two sides
Hook.
Further, the snap ring is connected on the plastic film by elastic band.
The beneficial effects of the utility model：
1, mounting is wound with the rotating cylinder of plastic foil on sandbox, directly pulled from rotating cylinder when needing overlay film plastic foil into
Row overlay film, the other places that need not take time again take plastic foil, convenient and efficient, save the time.
2, free end and the two sides edge of plastic foil are evenly equipped with snap ring respectively, the rotating cylinder other three that sandbox babinet is not arranged
A side is respectively arranged with the hook coordinated with snap ring, and after plastic foil is covered in the upper port of sandbox babinet, snap ring hook is stuck in
On hook, ensure that plastic foil and the sealing of sandbox babinet coordinate.
3, one end of the utility model bottom plate is hinged on siding, and the bottom of bottom plate is provided with the gas for switch baseplate
Cylinder, sandbox directly drive bottom plate to open after pouring by cylinder, so that it may to realize the cleaning of molding sand and casting.
