Abstract
The utility model discloses a kind of resin-coated sand shell mould Casting Equipments,Including mold cavity,Compensated cavity,Sediment chamber and casting gate,The Casting Equipment has precoated sand to be made,The mold cavity is provided with cast gate,By pouring metal liquid to cast gate,Metal liquid enters mold cavity and flows into compensated cavity by sprue,Metal impurities in metal liquid are filtered and stored in by the filter device of compensated cavity bottom in sediment chamber,Metal liquid is returned to by return line flow in compensated cavity simultaneously,Metal liquid in compensated cavity, which is flowed by casting gate in casting die, to be completed to cast,And molten metal make up the difference by riser and shrinks to eliminate sand hole,Waste product caused by molding is bad,It is put simultaneously using three riser in 120 degree,One riser feeding, 3 casting,Casting is arranged in a ring,Both maximumlly using arranging space,It can accelerate casting rapid cooling again,Be conducive to eliminate shrinkage cavity shrinkage porosity.
Description
Technical field
The utility model is related to a kind of casting technique, the resin-coated sand shell mould casting technique of especially a kind of stent.
Background technology
Precoated sand is invented by German Crow doctor Ning during World War II, and technical process is by the thermosetting of powdery
Property phenolic resin and roughing sand mechanical mixture, when heating cures.After develop into thermoplastic phenolic resin add latent curing agent (crow
Lip river tropine) and lubricant precoated sand is configured to by certain coating technique, be coated on sand grain surface when precoated sand is heated
Resin melting, under the action of the methylene decomposited in methenamine, the resin of melting is rapidly transformed by linear structure not to be melted
The three-dimensional-structure melted, so as to make precoated sand curing molding.The routine casting mode of production is tide mould sand moulding, and sand mold has higher hang
Sand, be easy to cause that part molding of codding is bad and knockout defect, and due to the limitation of tide mould sand sculpting method, casting is arranged unsuitable
It is overstocked so that product yield ratio is not high.
Utility model content
The purpose of this utility model is to provide a kind of resin-coated sand shell mould Casting Equipment, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical solution：A kind of resin-coated sand shell mould Casting Equipment, including
Mold cavity, compensated cavity, sediment chamber, riser and casting gate, it is characterised in that：Cast gate is provided at the top of the mold cavity, it is described to pour
Mold cavity bottom is provided with sprue, and the compensated cavity is connected by sprue with mold cavity, and compensated cavity bottom be provided with it is heavy
Slag chamber is provided with filter screen between the sediment chamber and compensated cavity, the compensated cavity is provided with casting gate away from sprue side,
And casting gate is connected with casting.
Preferably, sediment bottom of chamber portion is provided with return duct, and the return duct other end is connected with compensated cavity.
Preferably, riser is provided at the top of the compensated cavity and feeding is carried out to casting, in order to avoid most thick big portion after casting solidification
The center portion of position generates hole class defect.
Preferably, the compensated cavity is connected by bolt with sprue, and washer is provided between bolt and sprue.
Preferably, a whole set of Casting Equipment is made of precoated sand.
Compared with prior art, the beneficial effects of the utility model are：The beneficial effects of the utility model are：Design one
Kind resin-coated sand shell mould casting technique equipment so that a kind of stent high yield rate produced, mould arrangement more than one piece, product yield ratio
It is high.Tide mould sand moulding is substituted using the sculpting method of resin-coated sand shell mould, utilizes the precoated sand shell intensity spy higher than tide mould sand intensity
Point can reduce the usage amount of precoated sand, and make up the difference to molten metal by riser by reducing Casting Equipment wall thickness
It shrinks to eliminate sand hole, the bad caused waste product of molding, while three riser are put in 120 degree, 3 castings of a riser feeding
Part, casting are arranged in a ring, not only maximumlly using space is arranged, but also can accelerate casting rapid cooling, are conducive to eliminate shrinkage cavity
Shrinkage porosite.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, a kind of embodiment provided by the utility model：A kind of resin-coated sand shell mould Casting Equipment, including pouring
Mold cavity 2, compensated cavity 5, sediment chamber 7, riser 4 and casting gate 8, it is characterised in that：2 top of mold cavity is provided with cast gate 1, institute
It states 2 bottom of mold cavity and is provided with sprue 3, the compensated cavity 5 is connected by sprue 3 with mold cavity 2, and 5 bottom of compensated cavity
Portion is provided with sediment chamber 7, and filter screen 6 is provided between the sediment chamber 7 and compensated cavity 5, and the compensated cavity 5 deviates from sprue 3
Side is provided with casting gate 8, and casting gate 8 is connected with casting.
Operation principle：The utility model substitutes tide mould sand moulding using the sculpting method of resin-coated sand shell mould, utilizes precoated sand
