In technique scheme, owing to compressed air and molding sand are all to be led to by the sand of penetrating in the cylinder structure of sand shooting mouth
Road enters in core box, and therefore, in existing core-shooting process, the gas sand ratio in sand shooting mouth and core box is the most constant.Thus,
Prior art is difficult to meet demands more different than requiring for gas sand when penetrating sand and consolidation.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of sand shooting mouth, is improved by structure, penetrates sand gas sand effectively reducing
The consolidation of core box Sand is not affected, to reduce sand shooting mouth and the damage of core box while Bi.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of sand shooting mouth, including sand shooting mouth originally
Body, described sand shooting mouth body is followed successively by the first nozzle section and the second nozzle section along its length, and described first nozzle section has
First lateral wall and the first free end face, described second nozzle section has the second lateral wall and the second free end face, and described first
The sand-spraying hole of lateral wall and sand ejection board mates fixing connection, and described second lateral wall is mated with the sand-spraying hole of core box and is slidably connected,
Between described first free end face and described second free end face, through being provided with penetrates sand passage, and described sand shooting mouth is the most internal also to be set
Being equipped with gas distribution channel, one end of described gas distribution channel runs through described second free end face, and the other end of described gas distribution channel is even
The other end penetrating sand passage or described gas distribution channel described in Tong connects with compressed gas source through sand shooting mouth outer body wall.
In technique scheme, owing to being provided with gas distribution channel, in core-shooting process, Partial shrinkage gas can shunt process
Gas distribution channel enters core box from the second free end face, thus, the gas sand in sand shooting mouth exit than reducing, reduce sand shooting mouth and
The impulsive force of core box, and simultaneously, the ratio of the gas sand in core box increases, and consolidation to molding sand in core box is better achieved.
In technique scheme, penetrating sand passage described in the other end connection of described gas distribution channel, gas distribution channel leads to penetrating sand
The junction in road is provided with drainage screen, and the aperture of described drainage screen is less than the size of molding sand.
Preferably, penetrate at least some of for inverted taper type of sand passage described in so that described in penetrate sand passage and be positioned at the
Aperture at two free end faces is positioned at the aperture at the first free end face less than penetrating sand passage；Described gas distribution channel penetrates sand with described
The aperture, horizontal cross-section of sand passage is penetrated more than the aperture at the second free end face at channel connection.
Or, described sand shooting mouth body also has the between described first nozzle section and described second nozzle section the 3rd to penetrate
Mouth section, described 3rd nozzle section has the 3rd lateral wall, and the width dimensions of described 3rd lateral wall is more than described second lateral wall
Width dimensions, through to described 3rd lateral wall of the other end of described gas distribution channel and connect one end of trachea, described gas
Pipe connects through the other end of the 3rd adjacent nozzle section and described trachea with compressed gas source.
In technique scheme, described first lateral wall is provided with external screw thread, and the sand-spraying hole of described sand ejection board is provided with interior spiral shell
Stricture of vagina, threadeds with the sand-spraying hole of described sand ejection board in described first lateral wall.Can also connect otherwise sand shooting mouth with
Sand ejection board.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that
1. this utility model is provided with gas distribution channel in sand shooting mouth, and when penetrating sand, compressed air drives molding sand through penetrating sand
Mouth, enters core box；When molding sand is filled into a certain degree, and core box external and internal pressure subtractive is little, the molding sand in loophole is difficult to fill further
Being filled in core box die cavity, when molding sand is difficult to continue consolidation, Partial shrinkage air enters core box by the gas distribution channel in sand shooting mouth
In, continue to drive molding sand motion, thus improve the interior pressure differential with loophole of core box, promote the motion of molding sand further, improve core
The degree of packing of box Sand.
2., by arranging the gas distribution channel connected with compressed gas source, shooting pressure can be effectively reduced and penetrate the energy of sand
Consume, be effectively improved mobility and the degree of packing of molding sand, greatly reduce the damage of nozzle and mould.
