Description
Technical field
This utility model relates to a kind of gate stick, waters particularly to a kind of adjustable length model casting
Mouth rod.
Background technology
Model casting is also known as lost-wax casting.Model casting typically refers to make mould at fusible material
Sample, if making shell at apperance Surface coating dried layer refractory material, then melts discharge type by apperance
Shell, thus obtain the casting mold without die joint, after high-temperature roasting, get final product the casting side of back-up sand cast
Case.Owing to the widely used wax material of apperance manufactures, therefore often it is referred to as model casting losing wax casting
Make, and the pouring procedure of existing casting is to use traditional precision casting technology design concept to set
Meter.Due to hot investment casting part product compared with sand foundry goods less, it is impossible to sand casting equally use
Individually running gate system, can only be poured into a mould by runner system.Rising head casting is that alloy molten solution is straight
Connect and pour into following die cavity from watering casting rod running channel, owing to the speed poured at the beginning is fast, from cast gate
Alloy molten solution out splash can produce little metallic particles and enter die cavity, this defect be mostly by
In product the splash metallic particles produced and the thicker oxygen of generation of alloy molten solution in casting process
Change film and enter generation after die cavity mixes with alloy molten solution.To this end, it is proposed that a kind of length can
Adjust model casting gate stick.
Utility model content
Main purpose of the present utility model is to provide a kind of adjustable length model casting gate stick,
Water rod A by setting, water rod B and water the freely adjustable length watering rod of rod C, meet difference
The demand of cast die cavity, by buffering laminar flow device, alloy molten solution enters bigger in narrow running channel
Cushion chamber after, after cushion chamber is filled, the reduced velocity flow of alloy molten solution, the liquation after slowing down
Will not splash from cast gate and produce metallic particles entrance die cavity, liquation is from watering the filling of casting rod upper end simultaneously
Entering, the alloy molten solution of front end can produce thickness with the oxygen effect in running channel air after entering running channel
Thick layer oxide film, the oxide layer of alloy molten solution can be introduced into cushion chamber, will not enter type
Chamber, prevents forming curves shape and irregular cast defect in alloy-steel casting, improves the matter of cast
Amount, arranges ingate symmetrically by each side at through running channel, can avoid gate stick
Centre-of gravity shift, ensures gate stick not run-off the straight, can effectively solve the problem in background technology.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of adjustable length model casting gate stick, including watering rod A, watering rod B and water rod C,
Described watering is provided with connection external screw thread bottom rod A, described in water rod B top and bottom is respectively equipped with even
Connect female thread and connect external screw thread, described in water rod C top be provided with connection female thread, described in water rod
A is connected by the connection external screw thread watered on rod A and the connection female thread watered on excellent B with watering rod B,
Described water rod B and water rod C by water rod B on connect external screw thread and water rod C on connection in
Threaded, described in water rod A and water rod C by water rod A on connection external screw thread and water rod C
On connection female thread connect, described in water rod A, water rod B and water and be equipped with and run through inside rod C
Running channel, described in run through running channel and be provided with ingate, described in water rod A and be provided with pouring slot.
Further, water described in and be provided with buffering laminar flow device, described buffering laminar flow device bottom rod C
Inner side is provided with cushion chamber, described through running channel connection cushion chamber.
Further, described cushion chamber horizontal cross-section is rectangle, described in run through running channel level and cut
Face is circular.
Further, water described in and be provided with prolongation and water between through running channel and cushion chamber on rod C
Road.
Further, it is multiple for watering rod B (5) described in.
Compared with prior art, this utility model is had the advantages that and is watered by setting
Rod A, water rod B and water the freely adjustable length watering rod of rod C, meeting difference cast die cavities
Demand, by buffering laminar flow device, after alloy molten solution enters bigger cushion chamber in narrow running channel,
After being filled by cushion chamber, the reduced velocity flow of alloy molten solution, the liquation after slowing down will not fly from cast gate
Spattering generation metallic particles and enter die cavity, liquation is to pour into from watering casting rod upper end simultaneously, the conjunction of front end
Gold liquation can produce a thick layer of oxygen with the oxygen effect in running channel air after entering running channel
Changing film, the oxide layer of alloy molten solution can be introduced into cushion chamber, will not enter die cavity, prevents from closing
Gold foundry goods in forming curves shape and irregular cast defect, improve cast quality, by
Each side of through running channel arranges ingate symmetrically, can avoid the centre-of gravity shift of gate stick,
Ensure gate stick not run-off the straight.
