Description
Technical field
The utility model is related to machine casting technical field, more specifically, it relates to a kind of sand of large complicated shape
Core lamps structure.
Background technology
Diesel-engine body is the skeleton of Diesel engine, is the basis of each mechanism's work of engine, subjects engine
Various loads.Therefore, there is an organism sufficiently high rigidity and intensity just can ensure that the long-term normal work of each mechanism of engine.
Wherein, engine body push rod room is the important component of body, and for the large-scale body in part, push rod room position is complex-shaped
And all directions change is irregular, therefore, in order to ensure smoothly casting out for push rod chamber shape, the manufacturing process and core of push rod room core
Quality is particularly important.Before casting during core manufacture craft, the push rod room core of large-sized diesel motor cylinder block leads to
It is low using manual core box coremaking efficiency frequently with manual core box coremaking, but because part cabinet size specification is larger, and work is strong
Degree is big, there is significant limitations during coremaking.
So that the push rod room core of argosy cylinder block makes as an example, due to its complex structure and direction polytropy can not be once
The demoulding, geomery are very big etc., generally logical using manual core box, assembled, the sectional making core that carries out wooden model in many loose piece forms,
Core is made after finishing, and is again dismantled loose piece one by one in order by the stripping means of " percussion ", so as to obtain single hop core, most
Multistage core is combined again eventually and obtains complete push rod room core.
The process of such large-scale body core is made often with a series of shortcomings, made core using manual core box
Quality is also slightly not enough, is mainly manifested in：
1st, labour intensity is big, due to being manual operation using the overall process of manual core box coremaking, consumes huge people
Power so that labour intensity is greatly increased, additionally, the making of core every time, needs to wait for core solidification, when this process needs more long
Between, also, core is sectional making, these all have a strong impact on the production efficiency of coremaking；
2nd, the core quality defect produced, using manual core box, loose piece is more, and each loose piece machining accuracy is not high, may
The problems such as causing loose piece fit clearance after the mutual cooperation between loose piece not in place, misalignment, long-term use to increase, have a strong impact on sand
The coremaking quality of core；
3rd, core goes out modulus problem, after having made core using manual core box, during core depanning, need to manually tap loose piece, has
Strike the risk of bad core.
Utility model content

Box and lower core box, and the mould underframe below lower core box, being provided with described upper core box can accommodate maximum length mould
The upper impression of nozzle, is provided with the lower impressions being adapted with core bottom, described upper core box and lower core box in described lower core box
And the height superposition sum of mould underframe is adapted with the final-assembly die height dimension of coremaking equipment；Set in described lower core box
Have a stripper apparatus that core can be detached the lower impressions, described stripper apparatus include the core ejection mechanism being connected with lower core box and
First auxiliary demoulding mechanism and second of the fabricated structure that can successively realize the demoulding twice respectively on the core ejection mechanism
Auxiliary demoulding mechanism.
Used as further improving, described upper core box and lower core box is respectively higher than the height of standard core box；Accordingly, institute
Height of the height of the mould underframe stated less than standard underframe.
Further, the increased height of the upper core box is 10mm, and the increased height of lower core box is 115mm, accordingly
, the height that described mould underframe is reduced is 225mm.
Further, described upper core box, lower core box and mould underframe are by the mould of intermetallic composite coating.
Further, described core ejection mechanism includes the lower plunger tip plate being connected with the lower core box and positioned at the lower plunger tip plate
On the lower plunger tip bar assembly that first auxiliary demoulding mechanism and the second auxiliary demoulding mechanism and core can be ejected lower core box.
Further, the first described auxiliary demoulding mechanism includes the first hollow appearance being fixedly linked with the lower core box
Receive block, be vertically actively plugged in this and first accommodate the first loose piece and the second loose piece on block and to filling, and positioned at described the
The 3rd loose piece above two loose pieces.
Further, the second described auxiliary demoulding mechanism includes the second hollow appearance being fixedly linked with the lower core box
Receive block, be vertically actively plugged in this second accommodate block on and to fill the 4th loose piece and the 5th loose piece, and respectively be located at institute
State the 6th loose piece and the 7th loose piece above the 4th loose piece and the 5th loose piece.
Beneficial effect
