Abstract
The utility model discloses a kind of evaporative pattern snap flask.Sandbox is made up of casing and bottom plate, and casing and bottom plate butted part are designed with band, and band includes seal groove and seal convexity.By guiding finger setting during installation sealing, to ensure the sealing of sandbox, seal groove and seal convexity are no less than two.Bottom plate bottom is designed with vacuum chamber, and casing is square or circular, can also carry evacuation passageway.Cast has cooled down, and calls casing away, molding sand is scattered, and exposes workpiece, and the separation of molding sand, workpiece and sandbox is realized without mould turnover.Band is cleared up, installation casing is stand-by.The utility model eliminates mould turnover equipment investment, has saved turnover machine equipment maintenance expense, has eliminated mould turnover potential safety hazard.
Description
Technical field
The present invention relates to lost foam casting field, the sandbox that specifically lost foam casting uses.
Background technology
Founding casing with vacuum method is the product that cavityless casting and the casting of V methods combine, technical process include module it is dry,
Hang and apply coating, drying, group case, in sandbox plus sand vibrations moulding, covering agricultural film, vacuumize, pour into a mould, cooling down, the process such as mould turnover.Pour
During note, high-temperature liquid metal gasifies module, and gas permeation coating is taken away by vavuum pump, the cavity after molten metal filling EPS gasifications,
Casting is formed after cooling.
Evaporative pattern sandbox when vacuumizing in order to keep vacuum state, it is desirable to which sandbox seals, and is generally made of one, pours
, it is necessary to which workpiece is routed up from sandbox after note cooling, for lost foam production line, hydraulic pressure turnover machine is designed with, is turned over
The equipment investment of punch-out equipment is larger, also has maintenance, power cost etc. after production., it is necessary to use overhead traveling crane for the production of nonproductive line
By mold turnover of sandbox, this mould turnover mode needs overhead traveling crane oblique pull is askew to drag, and operates against regulations, very dangerous.
The content of the invention
Present invention solves the technical problem that it is：Not mould turnover, the separation of casting, molding sand and sandbox is realized, eliminate mould turnover safety
Hidden danger.
The technical solution adopted in the present invention is：Including casing and bottom plate, the lower box edge designs have seal groove,
The Position Design corresponding with seal groove has seal convexity on the bottom plate, and seal groove forms sealing together with seal convexity
Band.The casing can be square or circular.
Further, the bottom plate bottom is designed with vacuum chamber.
Further, the seal groove and seal convexity are no less than 2.
Further, by guiding finger setting during the band Butt sealing.
Lost foam cast has been cooled down, and sandbox is moved into knockout position, calls casing away, molding sand is scattered to fall into following
Sand hopper, expose workpiece, hung out with day handlebar workpiece.Unnecessary molding sand is manually pushed into knockout bucket on bottom plate, member-retaining portion on bottom plate
Bed load of the molding sand as next moulding.Band is cleared up, bottom plate is moved to correct position, installation casing is stand-by.
The technological progress that the present invention obtains is：Hydraulic pressure turnover machine is not used, has been saved the equipment investment of costliness, has been eliminated and set
Standby maintenance and repair expense；It is low without using hydraulic station, power consumption；Operated without mould turnover, eliminate potential safety hazard.

Embodiment
Embodiment 1：Square hinged flask
If Fig. 1 is square hinged flask, it is made up of square box 1 and bottom plate 2, bottom plate 2 carries vacuum chamber 3, casing 1
Cavity is communicated by filter screen 4 with vacuum chamber 3.
Casing 1 and bottom plate 2 are sealed by band 6, and the band of casing 1 is located at the bottom of sandbox, and it is individual close to be machined with 2-3
Sealing groove 30, the band of bottom plate 2 are located at top edge, relative with the band position of casing 1, are machined with 2-3 and seal groove 30
Relative seal convexity 31.When casing 1 and bottom plate 2 assemble, seal convexity 31 is inserted in seal groove 30, and sealing is played to sandbox and is made
With.
In the appropriate location of sandbox, such as relative two corners, bottom plate 2 is designed with guide finger 11, the relative position of casing 1
Positioning hole is designed with, when casing 1 and bottom plate 2 assemble, in positioning hole insertion guide finger 11, seal convexity 31 inserts seal groove 30
It is interior.
To prevent square box from deforming, the welding reinforcement channel-section steel on casing, these are strengthened channel-section steels and constitute taking out very for casing 1
Empty passage 5, the passage can be directly connected to the vacuum lead of vacuum system by casing vacuum adapter 7, can also be by fast
Changing-over first 8 and pipeline 9 communicate with bottom plate vacuum adapter 10, then connect the vacuum lead of vacuum system.
Embodiment 2：Circular hinged flask
If Fig. 2 is circular hinged flask, it is made up of circular casing 1 and bottom plate 2, bottom plate 2 carries vacuum chamber 3, casing 1
Cavity is communicated by filter screen 4 with vacuum chamber 3.For casing 1 without design evacuation passageway, the sandbox is applied to the slightly smaller sand of size
Case.
The sealing of the sandbox and positioning method are the same as embodiment 1.
After casting pouring cooling, sandbox is moved to knockout region, hangs away casing 1, the molding sand of sandbox internal upper part falls into sand
In the knockout bucket of lower box part, expose workpiece, hung out with day handlebar workpiece.Unnecessary molding sand is manually pushed into knockout bucket on bottom plate 2, protects
Stay bed load of the part molding sand as next moulding.Band is cleared up, bottom plate 2 is moved to correct position, installation casing 1 is stand-by.
Using hinged flask, mould turnover operation is avoided, it is possible to achieve the separation of workpiece and molding sand and knockout, for disappearing
For mould production line, without the expensive hydraulic pressure turnover machine of procurement price, later turnover machine maintenance and maintenance cost are decreased,
Production power consumption is saved simultaneously.For nonproductive line mould turnover, potential safety hazard during mould turnover is eliminated.
