Technical field
The present invention relates to metal casting technique fields, more particularly, to a kind of core making machine.
Background technique
Core making machine is the equipment for manufacturing overlay film sand shell core using hot box, by foundry sand, thermoplastic phenolic resin, is hidden
Property curing agent (such as methenamine) mixing be made into precoated sand and inject in the core box with heating device, methenamine point after being heated
Solution, the resin of melting is rapidly transformed into the three-dimensional-structure not melted by linear structure, thus curing molding, shape forming core.
Core making machine in the prior art includes fuselage, mould bases, device for revolving and driving, sand storage bin and automatic sand adding mechanism, shifting
Dynamic formula blasting unit penetrates sand pressing device, sand-scraping mechanism, sand recovering mechanism, hydraulic system, pneumatic system, electric control system etc.；Its
Core manufacturing craft is general are as follows: mandril reset-dynamic model reset-molding, and-shooting cylinder is mobile in place-compress-penetrates sand-exhaust-pine
Open-shooting cylinder is mobile resets 180 ° of (strike-ofing)-mould bases overturning (vibration)-mould bases reset -90 ° of die sinking-dynamic models-and turn over ---
Plunger tip.
Core making machine makes the technical process of four cylinder exhaust pipe tube cores are as follows: setting coremaking parameter penetrates sand, solidification crust, discharge
Remaining sand, solidification, skinning etc.；To reduce the hollow wall thickness general control of gas forming amount tube core in 8-10mm, solidification process, core box overturning
It will go out from sand shooting mouth position without cured tube core hourglass after 180 °, it is ensured that tube core core box is hollow, but four cylinder exhaust pipes penetrate sand
Mouth position is hatch frame, therefore also needs stifled sand core finishing, i.e., increases stifled sand process in sand shooting mouth front end, this process manually blocks
Difficulty is big, working time is long, therefore can reduce coremaking efficiency, and rejection rate is bigger.
Summary of the invention
In view of this, the core making machine is reduced in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of core making machine
The difficulty of artificial stifled sand, promotes working efficiency, reduces rejection rate.
In order to achieve the above objectives, the invention adopts the following technical scheme:
A kind of core making machine, including rack include four guide rod columns and are arranged vertical in guide rod with sand unit, the rack is penetrated
Fixed plate one, fixed plate two, movable plate one and movable plate two on column fix lower core box, the activity in the fixed plate two
Upper core box is fixed on plate one, the fixed plate one and two outer side center of fixed plate consolidate position plate, and it is described to fix guide rail to plate two sides,
Described to fix flat-removing air cyclinder to plate middle part, the fixed stifled sand plate of the flat-removing air cyclinder telescopic end, the stifled sand plate two sides are described in
In guide rail.
Further, hydraulic cylinder is set on the movable plate one, movable plate one and movable plate described in the Driven by Hydraulic Cylinder
Two move along the guide rod column.
Further, the fixed L-type steel plate of the flat-removing air cyclinder telescopic end, the L-type steel plate are solid by pressing plate and stifled sand plate
It is fixed.
The beneficial effects of the present invention are:

Flat-removing air cyclinder, wherein the fixed stifled sand plate of flat-removing air cyclinder telescopic end, stifled sand plate two sides are located in guide rail；Therefore it is stretched by flat-removing air cyclinder
Contracting is mobile to control stifled sand plate, blocks stifled sand plate by flat-removing air cyclinder elongation after sand more than discharge part and penetrates Sha Kou, remaining
Remaining sand continues solidification crust, forms closed configuration penetrating sand mouth, reduces the difficulty of artificial stifled sand, promotes working efficiency, reduces useless
Product rate.
2, shell core machine of the present invention use hot box process, open mold vertical-parting, complete machine structure mainly by columns assemblies, penetrate
The composition such as sand component, rack unit.Entire rack is mounted on the base by left and right supporting plate, push-and-pull lower edge of the moving template in molding
Guide post moves left and right the coremaking process for completing molding, die sinking.Moving template is in die sinking due under the effect of solid plate upper spring top power
Sand core follows on moving template automatically, can be easily removed by hand.Slewing equipment is by cylinder push-and-pull rack drives supporting plate
Gear can pour out internal uncured extra sand core and form required shell core in 180 ° of range automatic turnings.Rack is certainly
180 ° of dynamic overturning empties remaining sand and forms shell core, this technique and divides the technique of mould that can save precoated sand 40% up and down, in this process
Tube core be it is hollow, do not close, solve the problems, such as that the closing of this tube core is hited sky.
