Abstract
A casting and forming device for an internal combustion engine body comprises a sand box and a lost foam sand mould thereof. The sand box is barrel-shaped and vertical; a PES lost foam model of the internal combustion engine body is vertically placed in the sand box and inclines 10 to 15 degrees with a vertical direction, and a plurality of branch pouring channels formed at the lower part of the model are communicated with a bottom pouring channel; one side of the bottom pouring channel is communicated with a vertical pouring channel extending out of a sandbox mouth upwards; and a head is connected to the upper part of the sandbox mouth at the upper end of the PES lost foam model. Because the PES lost foam model is adopted and the model is vertically placed in the sand box, the casting andforming device for the internal combustion engine body with the structure is packed and filled with sand through inclining 10 to 15 degrees with the vertical direction and can satisfy both the sand filling and the compaction requirements when the PES lost foam model is filled with sand, compacted and shaped and ensure the filling effect of metal liquid during the pouring under negative pressure,thereby satisfying the approximate fine casting requirements. The utility model has the advantages of simple casting procedure, high quality and low cost and is particularly suitable for casting and forming an internal combustion engine with four to six cylinders.
Description
Technical field:
The utility model relates to casting, the casting device of the IC engine airframe that particularly a kind of casting process is simple, product quality is high, cost is low.
Background technology:
The casting device of existing IC engine airframe, it includes sandbox and shaping mould, operations such as peeling this structure also will be played core, the demoulding, mould assembling and cast molding when casting after, complex procedures, difficulty are big, be prone to defectives such as casting deformation, burning into sand, dimensional discrepancy are big, mould shift, increased follow-up mach workload, the cost height.
Summary of the invention:
The purpose of this utility model provides the casting device of the IC engine airframe that a kind of casting process is simple, product quality is high, cost is low.
Technical solution of the present utility model is finished as follows, it includes sandbox and disappearance model sand mold thereof, it is characterized in that: sandbox is a vertical sandbox of tubular, the vertical PES disappearance mould apperance that is placed with an IC engine airframe in sandbox, its apperance and vertical direction tilt 10 °-15 °, its apperance bottom has a plurality of running channels to be communicated with on the bottom pour mold road, be communicated with a sprue that stretches out the sandbox mouth on bottom pour mold road one side direction, above the sandbox mouth, be connected with rising head in the upper end of PES disappearance mould apperance.The IC engine airframe casting device of this structure, owing to adopted PES disappearance mould apperance and be positioned in the sandbox apperance is vertical, with 10-15 ° of vanning of vertical direction inclination back-up sand, can guarantee molding sand filling and the packing requirement of PES disappearance mould apperance when back-up sand jolt ramming moulding, liquid metal filling effect in the time of can guaranteeing vacuum-assist pouring, reach nearly smart casting requirement, have the advantage that casting process is simple, quality is high, cost is low.Be particularly suitable for 4～6 cylinder IC engine body castings.
Description of drawings:
Accompanying drawing is the structural representation of the new property of this practicality.
The specific embodiment:
The utility model is to adopt PES disappearance mould to do body apperance 3, the bottom pour mold road 6 that in a vertical sandbox 5, a sprue 2 is set and is communicated with it, there are a plurality of running channels to link to each other on the bottom pour mold road with body apperance lower end, when placement machine phantom sample, adopt the 10-15 ° of vertical location of vertical tilt, carry out back-up sand jolt ramming moulding, can effectively reach the packing requirement of molding sand 4 fillings like this.During vacuum-assist pouring, from sprue is suitable for reading metal liquid stream is entered the disappearance model cavity through sprue, bottom pour mold road, waste gas is discharged to finish through rising head 1 and is filled type.
