Screw rod clamping slot 406 on two sides, with by way of inserting screw rod clamping slot 406 screw rod by the first core core box 401
Fixedly mount with the second core core box 402, two screw rod clamping slots 406 are set on two relative side walls of core box, use
Before core shooter core shooting rod core core box is fixed in advance, it is to avoid faulting of slab ends defect occurs in core.By the first core core box 401 with
Second core core box 402 is along maximum cross-section matched moulds, the rod core groove of the first core core box 401 and the second core core box 402
Rod core groove constitute rod core core box core core cavity 407, the rod core core box 40 after matched moulds is vertically attached to
In mounting groove, sand inlet 403 is faced with the sand shooting mouth group 102 of top locating slot 101, so that core sand is from top locating slot 101
Sand shooting mouth group 102 and sand inlet 403 enter the core core cavity 407 of rod core core box, gas outlet 405 and bottom locating slot
201 steam vent group 202 is faced, so that the air-flow of the core core cavity 407 of rod core core box is fixed from gas outlet 405 and bottom
The steam vent group 202 of position groove is discharged.
Wherein, the number of the rod core groove arranged on the face that the first core core box 401, the second core core box 402 contact
Measure as two, to constitute two core core cavities, the core core cavity 407 of two rod core core boxes is set in parallel in rod core sand core core
In box 40 and do not connect, " people " font passage is passed through between the core core cavity 407 of sand inlet 403 and two rod core core boxes
404 connections, so that core sand is entered from sand inlet 403, and respectively enter two rod core core boxes along " people " font passage 404
Core core cavity 407 in.When penetrating sand, rod core core box 40 can simultaneously make two rod cores.Wherein, for vertically placing
The upper end of one core core box 401 and the second core core box 402 arranges " people " font groove, " people " font of the first core core box 401
Groove is connected with the rod core groove on the first core core box, " people " the font groove of the second core core box 402 and the second core core box
On the connection of rod core groove, the first core core box 401, " people " font groove of the upper end of the second core core box 402 face, such as
This is constituting " people " the font passage 404.
Wherein, the bottom of bottom core shooting core box 20 arranges plunger tip bar 203, and plunger tip bar 203 is multiple, multiple plunger tip bars 203
Position and top core shooting core box 10 it is corresponding with the position of the core core cavity of the composition of bottom core shooting core box 20, core shooting is completed
The core jack-up for being formed afterwards.Wherein, just multiple tops are arranged to the position of bottom locating slot 201 in the bottom of bottom core shooting core box 20
Core bar 203, the plunger tip bar 203 through bottom locating slot 201 bottom with the rod core core box in the mounting groove
40 contacts, by the jack-up of rod core core box 40 after the completion of core shooting.So can jack-up as needed rod core core box
The area of 40 bottom surfaces and its weight size arrange multiple plunger tip bars 203.

The top locating slot 101 of core core box 10 is aligned after rod core core box 40 installs, and is being assembled up with bottom core shooting core box 20, so
The core shooting core box for assembling is placed in core shooter afterwards starts to penetrate sand, core sand is in compressed air and acceleration of gravity double action
Under, by " people " font passage of the sand inlet 403 of the sand shooting mouth group 102 and rod core core box 40 of top core shooting core box 10
The 404 core core cavities 407 for injecting rod core core box, gas is from the gas outlet 405 of rod core sand core core box and bottom core shooting core box
Steam vent group 202 discharge rapidly, it is ensured that penetrate real rod core.Penetrate after sand finishes, by top core shooting core box and bottom core shooting core
Box is molded, plunger tip bar ejection rod core core box, and the die sinking of rod core core box is being taken out into rod core.
The all cores needed when the present invention is by a cast casting are fully integrated and are arranged in a core shooting core box, wherein
Including rod core, due to the elongate form of rod core, small volume, quantity it is more, if water is used together with other cores
Divide mould, horizontal core shooting equally, referring to Fig. 7, the unreal defect of sand is penetrated in the inside that there is rod core sand core, and the present invention is independent by rod core
Independent rod core core box 40 is set, is divided after mould using maximum cross-section, mounting groove is reserved on core shooting core box 1, by rod sand
Core core box 40 is inserted in mounting groove, so by rod core core box along maximum cross-section perpendicular to the horizontal parting face of core shooting core box
It is nested in core shooting core box, while the horizontal core shooting of other cores in core shooting core box is ensured, rod core adopts vertical core shooting,
After starting penetrating sand machine, under compressed air and acceleration of gravity double action, core sand is entered core sand by rod core core box 40
Sand mouth 403 injects the core core cavity 407 of rod core core box, and gas outlet 405 and steam vent group 202 of the gas from below core box is fast
Speed is discharged, it is ensured that penetrate real rod core.When in process of production some rod core is damaged, or need manual core making
When, can be used alone rod core core box 40 carries out manual core making, does not start core shooter production, while reducing production cost
Convenient production.
