Description
Technical field
The present invention relates to the technical field of core shooter structure, be specially a kind of evacuation and penetrate sand structure.
Background technology
Core shooter is to utilize compressed air that molding sand is injected sandbox pre-consolidation equably, applies pressure the most again and is compacted
Machine, existing core shooter penetrate sand part directly down side cavity body of mould carry out penetrating sand, although penetrated by pressure
Sand, but in mould, the degree of packing of sand is the highest, and then make that product degree of compaction is low, surface smoothness is low, also have in size micro-
Little deviation.
Summary of the invention
For the problems referred to above, the invention provides a kind of evacuation and penetrate sand structure, it guarantees rear consolidation in sand entrance mould
Degree height, and then make product degree of compaction height, any surface finish, clear-cut, size is accurate.
A kind of evacuation penetrates sand structure, and its technical scheme is such that it and includes that upper part penetrates the mould of head unit, bottom
Structure, described mould structure is supported on described workbench, it is characterised in that: the lower section of described workbench is provided with vacuum frame, institute
The lower end stating vacuum frame is provided with lift cylinders, and described lift cylinders can drive described vacuum frame vertically to movement, described vacuum frame
Bleeding point is external in vacuum pump by telescoping tube, and the air intake of described vacuum frame is arranged towards the air entry of described workbench, institute
Stating air entry and connect the bottom gap of described mould structure, described bottom gap is communicated to the die cavity of described mould structure.
The lower end of its center being further characterized by described vacuum frame is provided with connection pedestal, described linker
The lower end of seat is fastenedly connected with the upper piston bar of lift cylinders, and the lifting of described lift cylinders drives vacuum frame vertically to movement；
The bottom outside of described vacuum frame is evenly equipped with guide post pedestal, the bottom of described guide post pedestal be installed in described in lead
To the top of bar, described guide post vertically to running through the corresponding through hole of base plate, described guide post guarantee vacuum frame vertical to
The most mobile；
The cylinder body of described lift cylinders is installed in described base plate；
The position of described bleeding point fastens equipped with seal sleeve, and the outlet of described seal sleeve exposes to described vacuum frame
Lower surface, the lower end of described seal sleeve is set with the entrance anchor ring of described telescoping tube, the lower end outer ring surface of described seal sleeve
Being close to the inwall of the entrance anchor ring of described telescoping tube, the outer wall of the entrance anchor ring of described telescoping tube is set with sealing hold-down ring, really
Protect the sealing of seam.
Use the present invention structure after, core shooter penetrate sand before, by lift cylinders rise so that vacuum frame rise, vacuum frame
The air intake of upper surface be close to the air entry of described workbench, and then make the air entry of workbench be communicated to mould structure
Die cavity, core shooter be close to mould structure penetrate sand mouth after, vacuum pump has started the evacuation for die cavity, and vacuum pump closes afterwards
Closing, keep the vacuum state of die cavity, sand penetrated by core shooter so that sand enters in the die cavity of negative pressure state, it is ensured that sand enters in mould
The rear degree of packing is high, so make product degree of compaction height, any surface finish, clear-cut, size accurate, during the demoulding, the decline of vacuum frame,
Guarantee the normal demoulding of mould structure.
