Abstract
A kind of pick housing of pneumatic pick mold, including external mold and internal model are the utility model is related to, for the internal model to insert and using siphunculus through the core of external mold, sand core rod, siphunculus tube wall is provided with through hole.The utility model current rapid heat conduction cooling, reduces core instantaneous temperature, ensures sand core strength in use, siphunculus accesses water main water flowing when molten iron pours into mold cavity, and then avoids the bending of core, deformation and defeated and dispersed；Avoid casting inner eccentric holes from losing the quality problems such as circle, internal burning into sand to occur；Hole forming in casting is conformed to quality requirements, ensure the casting qualification rate of pick housing of pneumatic pick.
Description
Technical field
It the utility model is related to a kind of pick housing of pneumatic pick mold.
Background technology
Pneumatic pick is the industry indispensability instruments such as mine, railway, highway, tunnel, factory, construction building site, and main rise crushes
Effect, the market demand are very big.Several big Pneumatic Tools Factory year production all kinds of pneumatic picks of hundreds of thousands part in China, are using pneumatic pick conservative estimation
There are millions of.
Pick housing of pneumatic pick is the essential core part of pneumatic pick, and it is inner via hole pipe fitting type casting, and core is elongated, works as high temperature liquid iron
When filling type cast, core is wrapped up by molten iron, because of core limited thermostability, now easily causes core bending, deformation and defeated and dispersed,
Cause casting inner eccentric holes to lose the quality problems such as circle, internal burning into sand to occur.Therefore, it is badly in need of a kind of pick housing of pneumatic pick mold of design to come really
The stabilization of core quality is protected, so as to reduce casting quality problem, improves product qualification rate.
The content of the invention
Problem to be solved in the utility model is to provide a kind of pick housing of pneumatic pick mold, and the pick housing of pneumatic pick mold is in high temperature iron
When water fills type cast, the stabilization of core can be kept, hole forming in casting is conformed to quality requirements, avoid casting inner eccentric holes from losing
The quality problems such as round, internal burning into sand occur；Ensure the casting qualification rate of pick housing of pneumatic pick.
Technical scheme provided by the utility model is：A kind of pick housing of pneumatic pick mold, including external mold and internal model, the internal model are
Insert and run through the core of external mold, sand core rod uses siphunculus, and siphunculus tube wall is provided with through hole.
The siphunculus is circular siphunculus.
The external mold is made up of sandbox and the molding sand being arranged in sandbox.
The utility model is in use, siphunculus accesses water main water flowing, the rapid heat conduction drop of current when molten iron pours into mold cavity
Temperature, core instantaneous temperature is reduced, ensure sand core strength, and then avoid the bending of core, deformation and defeated and dispersed；Avoid casting endoporus
The quality problems such as non-concentric, out-of-round, internal burning into sand occur；Hole forming in casting is conformed to quality requirements, ensure the casting of pick housing of pneumatic pick
It is molded qualification rate.Through hole is set on siphunculus tube wall（Run through the perforation of tube wall）, the irregular structure on one side arbor siphunculus surface
Ensure that sand is adhered on siphunculus, increase adhesive force, on the other hand ensure that the heated caused gas of fuse and heat can be rapid
Arbor siphunculus is imported by hole, avoids the generation of gas hole defect.
Brief description of the drawings
Fig. 1 is overall schematic outside the utility model pick housing of pneumatic pick Water-cooled core；
Fig. 2 is the utility model pneumatic pick casting mold internal structure schematic diagram；
Fig. 3 is the utility model arbor siphunculus schematic diagram.
Embodiment
Referring to Fig. 1-3, pick housing of pneumatic pick mold described in the utility model, including external mold and internal model, the internal model are insertion
And siphunculus is used through the core 5 of external mold, sand core rod 3, siphunculus side wall is provided with through hole 10.
The siphunculus is circular siphunculus.
The external mold is made up of sandbox 9 and the molding sand 7 being arranged in sandbox 9.
For the utility model in use, after 8 times core mould assembling of casting moulding, arbor siphunculus 3 accesses water main 1, waits casting to be cast
Part 4.Molten iron starts pouring cast part in predetermined temperature, opens the water valve 6 of water inlet pipe 2 during cast, makes the water flowing of arbor siphunculus 3；Current are fast
Fast heat conduction cooling, reduces the instantaneous temperature of core 5, ensures sand core strength, and then avoids the bending of core, deformation and defeated and dispersed；Keep away
Exempt from casting inner eccentric holes and lose the quality problems appearance such as circle, internal burning into sand；Hole forming in casting is conformed to quality requirements, ensure pneumatic pick
The casting qualification rate of cylinder body.After the complete 3min of casting pouring, water valve is closed, unclamps water inlet pipe.Casting waits and takes off case.
The utility model uses heat balance principle, by adjusting flow velocity and inflow temperature, to adjust temperature speed.
The utility model advantage and meaning
（1）Sand core rod uses siphunculus, is drilled on siphunculus, and siphunculus accesses water main water flowing, current when molten iron pours into die cavity
Heat is taken away, technical process is simple to operate, and improves the qualification rate of casting.
（2）The rapid heat conduction cooling of current, reduces core instantaneous temperature, ensures molding sand core rigidity, and then avoid core
Flexural deformation.
（3）Current take away heat, reduce parcel molten iron to the scald of core, avoid binding agent by thermal failure, subtract
Lacked because core it is defeated and dispersed caused by burning into sand defect.
Claims (3)
1. a kind of pick housing of pneumatic pick mold, including external mold and internal model, it is characterised in that：The internal model is for insertion and through the sand of external mold
Core, sand core rod use siphunculus, and siphunculus tube wall is provided with through hole.
2. pick housing of pneumatic pick mold according to claim 1, it is characterised in that：The siphunculus is circular siphunculus.
3. pick housing of pneumatic pick mold according to claim 1 or 2, it is characterised in that：The external mold is by sandbox and is arranged at sand
