Description
Technical field
The invention belongs to evaporative pattern manufacture fields, are related to a kind of sandbox.
Background technique
Lost foam casting (is that paraffin similar with casting dimension shape or bubbles model bonding are combined into model cluster, brushes
After applying fireproof coating and drying, it is embedded in vibration molding in drystone sand, is poured under negative pressure, model is made to gasify, liquid metals accounts for
According to modal position, the novel casting method of casting is formed after solidification is cooling, is compared with tradition sand mould casting method, it is possible to reduce
40% to 50% machining time.Cast sandbox when in use, exhaust tube is often arranged at one end, not can guarantee in sandbox
It presses, while sieve is single layer, filter effect is poor, and is inconvenient when replacement sieve.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of pumping pressure uniformly, and sieve replaces a kind of convenient sandbox.
A kind of sandbox of the present invention, including sandbox ontology, the interior sandbox ontology is cavity, and the cavity is divided by partition
Upper cavity and lower chamber roll between the partition and cavity and are connected, and the side of partition is provided with rolling mechanism, other side setting
There is close mechanism, two opposing sidewalls are equipped with sliding rail in cavity, and the rolling mechanism is mutually matched with sliding rail, the roller press
Structure includes bracket and pulley, and the bracket is mounted on partition side end surface, and the pulley is fixed at below bracket, described to close
Close mechanism include baffle and connector, the baffle is arranged along the vertical direction, and one end is connected with partition, set on baffle there are two
Connector, the connector are connected with sandbox ontology screw thread, the partition be equipped with upper layer and lower layer sieve, respectively wide-meshed screen and
Fine screen mesh；The lower chamber is provided with multiple pump-lines, and the pump-line is four, is evenly distributed on four of lower chamber
On side, one end of exhaust tube is located in lower chamber, and the other end is arranged in outside and is connected with aspiration pump.
Preferably, it is equipped with cover board at the top of the upper cavity, described cover board one end is movably connected with sandbox ontology.
Preferably, the sandbox body bottom portion is equipped with idler wheel, and idler wheel passes through support axis connection sandbox ontology.
Preferably, one layer of sealing ring is additionally provided between the baffle and sandbox ontology.
Preferably, the aperture on the wide-meshed screen is greater than the pore size on fine screen mesh.
Preferably, the sandbox body outer wall is equipped with handle.
Preferably, the sandbox body outer surface is equipped with rust-proof coating.
The present invention compared with the existing technology, achieves technical effect below:
The configuration of the present invention is simple, design rationally, lower chamber is uniformly provided with multiple pump-lines, can guarantee with pumping so that
Vacuum degree keeps uniformly, improving product quality effect in cavity；Sieve can be cooperated when being filtered by pulley and sliding rail,
The replacement for facilitating sieve improves service efficiency, while sieve can be further improved the filtering effect of sieve using two layers of setting
Fruit.

Specific embodiment
A kind of sandbox of the present invention, including sandbox ontology, the interior sandbox ontology is cavity, and the cavity is divided by partition
Upper cavity and lower chamber roll between the partition and cavity and are connected, and the side of partition is provided with rolling mechanism, other side setting
There is close mechanism, two opposing sidewalls are equipped with sliding rail in cavity, and the rolling mechanism is mutually matched with sliding rail, the roller press
Structure includes bracket and pulley, and the bracket is mounted on partition side end surface, and the pulley is fixed at below bracket, described to close
Close mechanism include baffle and connector, the baffle is arranged along the vertical direction, and one end is connected with partition, set on baffle there are two
Connector, the connector are connected with sandbox ontology screw thread, the partition be equipped with upper layer and lower layer sieve, respectively wide-meshed screen and
Fine screen mesh；The lower chamber is provided with multiple pump-lines, and the pump-line is four, is evenly distributed on four of lower chamber
On side, one end of exhaust tube is located in lower chamber, and the other end is arranged in outside and is connected with aspiration pump.At the top of the upper cavity
Equipped with cover board, described cover board one end is movably connected with sandbox ontology.The sandbox body bottom portion is equipped with idler wheel, and idler wheel passes through support
Axis connection sandbox ontology.One layer of sealing ring is additionally provided between the baffle and sandbox ontology.Aperture on the wide-meshed screen is greater than
Pore size on fine screen mesh.The sandbox body outer wall is equipped with handle.The sandbox body outer surface is equipped with rust-proof coating.
In use, opening cover board 9, molding sand is put into sandbox ontology, then phantom cast is put into molding sand, and
By sand molding, poured, in casting process, molding sand temperature can increase and gradually gasify, at this moment, start aspiration pump,
Aspiration pump can be released the gas of sandbox this weight by the way that four exhaust tubes 4 of lower chamber 3 are arranged in, due to four exhaust tubes
4 are uniformly arranged, and the mode gas bleeding that can faster and press carries out casting；After the completion of casting, casting is taken out, by sandbox sheet
Extra molding sand takes out in vivo, and remaining molding sand can be used for casting next time, and one layer is had after being used for multiple times, on sieve and is evident that
Object is dumped, at this point, opening the connector 7 being connected with sandbox ontology screw thread when replacing sieve, holding cover board 9, pass through pulley 6
Partition 2 is pulled out from sandbox ontology, after pull-out, wide-meshed screen and fine screen mesh are replaced, is being put by pulley 6 with sliding rail
Into sandbox ontology, it is attached by connector 7, it is easy to use.
