Abstract
The utility model discloses an easy-to-turn expendable pattern casting sand box. One side wall of the sand box body is a side door which can be opened to take out a casting; a seal door is arranged outside the side door; a supporting roll is arranged at the bottom of the side door; a balance roll is arranged at the position corresponding to the supporting roll and is used for keeping balance of the sand box body ; a support frame is hinged to the supporting roll; a hoist ring is arranged on the sand box body on the surface corresponding to the side door, and is used for hoisting the rear part of the sand box body to cause the sand box body to rotate around the support frame to let the casting be taken out. The side door is arranged on the side part of the sand box; the supporting roll and the support frame are arranged at the bottom of the side door; the sand box body can be turned as long as a very small force is exerted on the rear part of the sand box, and the molding sand in the sand box can be poured out to complete the depanning operation; meanwhile, in order to prevent the molding sand from falling out of the side door, the seal door is arranged outside the side door; as the opening manners of the side door and the seal door are different, the sand box is effectively sealed.
Description
Technical field
The utility model relates to the evaporative pattern in machine casting field, specifically a kind of easily upset lost foam casting sandbox.
Background technology
Lost foam casting (claiming again cavityless casting) is with foamed plastics (EPS, STMMA or EPMMA) macromolecular material make become and the design of part that will produce casting, the duplicate full mold mould of size, (play strengthening through dip-coating fireproof coating, bright and clean, permeation functions) and dry after, be embedded in dry quartz sand through three-dimensional vibrating moulding, casting molding flask pours into molten metal liquid under negative pressure state, make macromolecular material model be heated gasification extract out, and then the novel casting method of being produced foundry goods by the disposal molding New Casting Technique forming after liquid metals replacement cooled and solidified.
Existing lost foam casting sandbox is exactly a simple sandbox, and after need to sandbox being sling by boom hoisting in mould turnover operation with in going out die process, carry out mould turnover or pour out molding sand wherein, so not only troublesome poeration, and also efficiency is also very low.
Utility model content
For the evaporative pattern sandbox that solves prior art is difficult to stir the problems such as caused efficiency is low at mould turnover with in going out die process, the utility model provides a kind of easy upset lost foam casting sandbox, this sandbox can complete out modulo operation by means of simple instrument, has greatly improved operating efficiency.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of easily upset lost foam casting sandbox, a sidewall of sandbox casing is the side door that can open to take out mold, the outside of side door is also provided with hermatic door, the bottom of side door has a backing roll, the position corresponding with this backing roll is provided with balance roller, for making sandbox casing held stationary; On described backing roll, be hinged with bracing frame, one side relative with side door on sandbox casing is provided with hoisting ring, for slinging sandbox casing rear portion make it rotate to take out the mold in it around bracing frame.
Described backing roll and balance roller are arranged on the bottom of sandbox casing in a rotatable manner, so that sandbox casing can move in the mode of rolling.
Described side door is single open-door or double door, and side door is opened or sealed to described hermatic door by sliding in the slide rail being provided with in side door both sides to realize.
Beneficial effect: the utility model is offered side door by the sidepiece at sandbox, and in side door bottom, backing roll and bracing frame are set, make like this to apply at sandbox rear portion a very little power and can realize the upset of sandbox, thereby the molding sand of pouring out wherein completes depanning operation; Meanwhile, in order to prevent that molding sand from shedding from side door, at side door outer setting one hermatic door, because the unfolding mode of side door and hermatic door is different, thereby realized the sealing to sandbox.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, sandbox casing, 2, backing roll, 3, balance roller, 4, hermatic door, 5, side door, 6, hoisting ring, 7, bracing frame.
Detailed description of the invention
As shown in the figure, a kind of easily upset lost foam casting sandbox, a sidewall of sandbox casing 1 is the side door 5 that can open to take out mold, the outside of side door 5 is also provided with hermatic door 4, the bottom of side door 5 has a backing roll 2, the position corresponding with this backing roll 2 is provided with balance roller 3, for making sandbox casing 1 held stationary; On described backing roll 2, be hinged with bracing frame 7, on sandbox casing 1, the one side relative with side door 5 is provided with hoisting ring 6, for slinging sandbox casing 1 rear portion make it rotate to take out the mold in it around bracing frame 7.
Be more than basic embodiment of the present utility model, can on above basis, be improved further or optimize:
As, described backing roll 2 and balance roller 3 are arranged on the bottom of sandbox casing 1 in a rotatable manner, so that sandbox casing 1 can move in the mode of rolling.
As, described side door 5 is single open-door or double door, side door 5 is opened or sealed to described hermatic door 4 by sliding in the slide rail being provided with in side door 5 both sides to realize.
Bracing frame 7 in the utility model rose not affect the balance of sandbox in used time not, was put down in use and supported on the ground, sandbox is overturn under external force as fulcrum, thereby its inner molding sand is poured out.
