This patent discloses a kind of casting device of evaporative pattern, including casing and bubbles model, molding sand is provided with the casing, bubbles model is inside molding sand, and bubbles model includes body and grooving, casing is additionally provided with the flexible packed layer to match with grooving, and the expanding block of some groups of pre- thermal expansions is provided with molding sand, every group of expanding block is oppositely arranged with packed layer, and every group is provided with support bar between expanding block and casing.This programme mainly solve the problems, such as because molding sand with bubbles model compactness is not high causes casting compliance rate low.
Description
Technical field
The invention belongs to casting and molding field, and in particular to a kind of molding sand for mould casting or similar casting mold.
Background technology
Lost foam casting be foam mould use bindless dry sand combination vacuum pumping technology cavityless casting, be by with
The similar bubbles model of casting dimension shape, which bonds, is combined into model cluster, after brushing fireproof coating and drying, is embedded in molding sand and shakes
Dynamic moulding, pours into a mould, model is gasified under negative pressure, and liquid metals occupies modal position, and the new of casting is formed after solidification cooling
Casting method.
At present, the casting compliance rate produced is relatively low, and it is main reason is that in casting manufacturing process, molding sand and foam mold
The compactness of type is not high, particularly to the bending section of casting, groove portion and hole portion.In the production process to elevator rope pulley, elevator
The bubbles model of rope sheave（Including body and grooving）The vibration molding in molding sand, the neighbouring sand compaction of grooving of bubbles model is not
It is enough, cause moulding of the bubbles model in molding sand imperfect, therefore reduce reaching for elevator rope pulley made from liquid metals cast
Mark rate.
The content of the invention
The invention is intended to provide a kind of casting device of evaporative pattern, to solve because of the degree of packing between molding sand and bubbles model
The problem of not enough causing casting compliance rate low.
In order to achieve the above object, base case of the invention is as follows：A kind of casting device of evaporative pattern, including casing and
Bubbles model, the casing is interior to be provided with molding sand, and the bubbles model is inside molding sand, and bubbles model includes body and rope
Groove, the casing are additionally provided with the flexible packed layer to match with grooving, and the swollen of some groups of pre- thermal expansions is provided with the molding sand
Expansion block, expanding block described in every group are oppositely arranged with packed layer, and every group is provided with support bar between expanding block and casing.
The principle of base case：During operation, casing is filled up using molding sand first, and molding sand covering packed layer, then by elevator
The bubbles model of rope sheave is put into molding sand, ensures that packed layer is embedded in grooving with molding sand, in addition, being also placed with molding sand some
Group expanding block, and ensure that every group of expanding block is oppositely arranged with packed layer；Then liquid metals is poured into a mould under negative pressure so that foam mold
Type gasifies, and the heat of liquid metals causes the pre- thermal expansion of expanding block, swollen under this state under the supporting role of support bar
Expansion block is extruded packed layer, because packed layer is flexible so that packed layer extrudes tight between layer of sand and bubbles model
Solidity is higher；Final liquid metal occupies modal position, and casting is formed after solidification cooling.
The advantages of base case：Compared to current casting manufacture device, this programme is coordinated using flexible packed layer meets
The expanding block extruding layer of sand of thermal expansion make it that the degree of packing between layer of sand and the grooving of bubbles model is higher, and then ensure that foam
The integrality of model moulding in molding sand, improve the compliance rate of elevator rope pulley.
Preferred scheme one：Based on scheme preferred scheme, the packed layer includes layer of sand and rubber successively from the inside to the outside
Poly-bag, the rubber bag fill up molding sand, and by above-mentioned setting, one entirety of molding sand filled rubber bag formation is used to extrude layer of sand,
Layer of sand fills grooving, improves the degree of packing between molding sand and the grooving of bubbles model；In addition, the molding sand of rubber bag can repeatedly make
With escapable cost.
Preferred scheme two：Preferably one preferred scheme, the rubber bag are provided with opening, set in the opening
There is the closure being detachably connected, by above-mentioned setting, the closure in opening opens and closes, and is easy to the filling of molding sand and close
Envelope, it is simple to operate.
Preferred scheme three：Preferably two preferred scheme, expanding block described in every group is triangular in shape, is set by above-mentioned
Put, according to the stability of triangle, extruding of the every group of expanding block to packed layer is more stable, improves the compliance rate of mould casting.
Preferred scheme four：Preferably three preferred scheme, the side wall of the casing is provided with link, by above-mentioned
Set, be connected using the hook of loop wheel machine with link, realize mechanization transportation, reduce manual labor.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the casting device embodiment of evaporative pattern of the present invention；
Fig. 2 is the structural representation of grooving.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Casing 1, molding sand 2, body 3, grooving 4, rubber bag 5, expanding block 6, extension
Ring 7.
Embodiment is basic as shown in accompanying drawing 1, Fig. 2：A kind of casting device of evaporative pattern, including casing 1, molding sand 2 and elevator
Sheave-like bubbles model, molding sand 2 fill trunkful body 1, and bubbles model is positioned over inside molding sand 2, and bubbles model includes body 3
With grooving 4, the packed layer to match with grooving 4 is connected with by iron chains on casing 1, packed layer includes layer of sand successively from the inside to the outside
With rubber bag 5, rubber bag 5 fills up molding sand, and the filled rubber bag 5 of molding sand 2 forms an entirety and is used to extrude layer of sand, layer of sand gasket for packing
Groove 4, improve the degree of packing between molding sand 2 and the grooving 4 of bubbles model；In addition, the molding sand of rubber bag 5 can be used for multiple times, can save
Cost-saving.
The expanding block 6 of some groups of pre- thermal expansions is provided with molding sand 2, and support is connected between every group of expanding block 6 and casing 1
Bar, every group of expanding block 6 are oppositely arranged with packed layer, and every group of expanding block 6 is triangular in shape, according to the stability of triangle, often
Extruding of the group expanding block 6 to packed layer is more stable, improves the compliance rate of mould casting.
In addition, offer opening in rubber bag 5, seal with screwed joint lid in opening, the closure in opening is opened and closed
Close, be easy to the filling and sealing of molding sand 2.Link 7 is connected with the side wall of casing 1, is connected using the hook and link 7 of loop wheel machine
