Two paratype chambers of drain pipe, wherein the top case is with offering the steam vent connected with paratype chamber in the side wall of drag box.
By using above-mentioned technical proposal, molten metal is first into primary cavity the air in primary cavity being squeezed into pair
In die cavity, discharged in the steam vent by being connected with paratype chamber, it can be ensured that the air emptying in die cavity, improve Forming Quality.
Preferably, the axis of the steam vent is parallel with the axis of paratype chamber.
By using above-mentioned technical proposal, molten metal from primary cavity when entering paratype chamber, direction that paratype chamber opens up
Determine the flow direction of molten metal, and the diameter parallel for opening up direction and paratype chamber of steam vent so that extruded by molten metal
Air out can take advantage of a situation discharges from steam vent, reduces because air drag causes die cavity molten metal in die cavity internal pressure mistake
Greatly, Forming Quality is improved.
Preferably, the sand mold mould also includes being contained in die cavity and symmetrically arranged upper core and lower core.
By using above-mentioned technical proposal, the setting of upper and lower core be initially used for molding cast-internal chamber and
Corresponding shape, difficulty can be reduced during core by being arranged on to make in addition using split type core, improve yield rate, secondly into
Core can also be used alone during type and either descend the casting that core coordinates top case or drag box molds half, just
In surface and internal processing, flexibility during shaping is improved.
In summary, the utility model has the advantages that：
1st, by setting cross gate, dividing running channel and being connected to cross gate and some ingates divided on running channel,
While shaping speed is improved, mobility of the molten metal in die cavity is improved, improves Forming Quality；
2nd, by opening up the steam vent connected with paratype chamber, and the steam vent side of opening up in side wall of the top case with drag box
To parallel with paratype chamber, it is easy to the discharge of air to reduce resistance, while improve the free rate of air；
3rd, the upper core of split settings reduces the difficulty for making core first with lower core, secondly can also flexibly select split
Or it is integrally formed out casting.
