Background technique
Currently, core box is widely used in the manufacture of casting sand type core with the popularization of core making machine.But core box is in reality
In the course of work, mandril ceaselessly moves up and down, friction is generated between mandril and core box ontology, the time is long, pushes up on core box ontology
Rod aperture will appear different degrees of abrasion, due to being limited by working environment, when mandril and mandril interporal lacuna are greater than 0.3mm, and top
Gravel is flowed between rod aperture and mandril, it will vicious circle occur, race sand will occur quickly in core box, gas leakage shows, and core box will
Operational failure needs replacing core box, causes biggish economic loss.
Summary of the invention
In view of the deficiencies of the prior art and defect, a kind of core box post rod mechanism is provided, the abrasion of core box can be reduced, significantly
The service life of core box ontology is improved, the expense of tooling investment is saved, improves the quality of coremaking.
To achieve the above object, the utility model provides following technical scheme.
A kind of core box post rod mechanism, including core box ontology are provided with sand core in core box ontology, top are provided on core box ontology
Rod aperture is slidably fitted with mandril in jogger hole, and mandril top is protruded into core box ontology through jogger hole, and ejector rod bottom end stretches out jogger hole
It is externally connected with mandrel plate, top stem casing is provided in jogger hole, for top stem casing between mandril and jogger hole inner wall, mandril passes through top
Rod set protrudes into core box ontology.
Further, top stem casing is equipped with lip, and core box ontology is equipped with lock screw, the bizet and top stem casing of lock screw
Lip offset so that top stem casing to be fixed in jogger hole.
Further, core box ontology is made of gray cast iron material, and top stem casing is made of bearing steel material.
Further, ejector rod bottom end is equipped with connector sleeve, and mandrel plate is equipped with the compact heap to offset with connector sleeve, and compact heap is logical
Screw is crossed to be fixed on mandrel plate.
Further, connector sleeve is connect by screw thread with mandril, and the lock nut with connector sleeve cooperation is additionally provided on mandril.
The utility model has the following beneficial effects: a kind of core box post rod mechanism, including core box ontology, it is provided in core box ontology
Sand core is provided with jogger hole on core box ontology, mandril is slidably fitted in jogger hole, core box sheet is protruded into through jogger hole in mandril top
In vivo, ejector rod bottom end stretching jogger hole is externally connected with mandrel plate, top stem casing is provided in jogger hole, top stem casing is located at mandril and top
Between rod aperture inner wall, mandril passes through top stem casing and protrudes into core box ontology.The core box post rod mechanism of the utility model, by mandril
Top stem casing is equipped in hole, so that mandril when moving up and down, rubs between mandril and top stem casing, without between jogger hole
It is in contact, is worn so as to avoid core box, greatly improve the service life of core box ontology, save taking for tooling investment
With, the quality of coremaking is improved, when wearing between mandril and top stem casing, only needs to change mandril and top stem casing, drop
Low replacement cost.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
In figure, 1. core box ontologies；2. sand core；3. mandril；4. mandrel plate；5. top stem casing；6. lock screw；7. connector sleeve；
8. compact heap；9. screw；10. lock nut.
Specific embodiment
The utility model is further illustrated in conjunction with attached drawing.
A kind of core box post rod mechanism shown in Figure 1, including core box ontology 1, core box ontology 1 is by gray cast iron material system
At hardness is provided with sand core 2 in HB200 or so, core box ontology 1, jogger hole is provided on core box ontology 1, in jogger hole
It is slidably fitted with mandril 3,3 top of mandril is protruded into core box ontology 1 through jogger hole, and 3 bottom end of mandril is stretched out jogger hole and is externally connected with
Mandrel plate 4,3 bottom end of mandril are equipped with connector sleeve 7, and connector sleeve 7 is connect by screw thread with mandril 3, and connector sleeve 7 is equipped with flanging, mandril
Plate 4 is equipped with the compact heap 8 to offset with connector sleeve 7, and compact heap 8 is fixed on mandrel plate 4 by screw 9, thus by connector sleeve 7
It is fixed on mandrel plate 4, the lock nut 10 cooperated with connector sleeve 7 is additionally provided on mandril 3, by rotation lock nut 10 and even
It offsets at the top of female connector 7, connector sleeve 7 is limited.
Top stem casing 5 is provided in jogger hole, top stem casing 5 is equipped with lip, and core box ontology 1 is equipped with lock screw 6, locking screw
The lip of the bizet and top stem casing 5 of silk 6 offsets, so that the lip of top stem casing 5 is fitted in core box ontology 1, top stem casing 5 is consolidated
Due in jogger hole, the quantity of lock screw 6 is two, and top stem casing 5 is made of bearing steel material, hardness in HRC60 or so,
The hardness of top stem casing 5 is much larger than the hardness of core box, and not easy to wear, top stem casing 5 is between mandril 3 and jogger hole inner wall, mandril 3
It is protruded into core box ontology 1 across top stem casing 5.
3 mechanism of core box mandril of the utility model, by being equipped with top stem casing 5 in jogger hole, so that mandril 3 is moved down upper
When dynamic, rub between mandril 3 and top stem casing 5, without being in contact between jogger hole, ground so as to avoid core box
Damage greatly improves the service life of core box ontology 1, saves the expense of tooling investment, the quality of coremaking is improved, when 3 He of mandril
When wearing between top stem casing 5, mandril 3 and top stem casing 5 are only needed to change, reduces replacement cost, replaces top stem casing 5
When, rotation lock screw 6 is only needed, so that lock screw 6 is separated with core box ontology 1, lock screw 6 no longer limits top stem casing 5,
Top stem casing 5 can be removed, replacement is convenient, when replacing mandril 3, screw 9 only need to be rotated, so that screw 9 is separated with mandrel plate 4, spiral shell
Nail 9 no longer limits compact heap 8, removes compact heap 8, so that between connector sleeve 7 and mandrel plate 4 respectively, mandril 3 can be taken out,
Replacement is convenient.
