Description
Technical field
The present invention relates to the technical fields of core shooter structure, and specially one kind, which vacuumizes, penetrates sand structure.
Background technique
Core shooter is that molding sand is equably injected to the pre- consolidation of sandbox using compressed air, then applies pressure again and is compacted
Machine, square cavity body of mould carries out penetrating sand directly down for the sand part of penetrating of existing core shooter, although being penetrated by pressure
Sand, but the degree of packing of sand is not high in mold, so that product compactness is low, surface smoothness is low, it is micro- also to have in size
Little deviation.
Summary of the invention
Sand structure is penetrated in view of the above-mentioned problems, vacuumizing the present invention provides one kind, ensures that sand enters rear consolidation in mold
Degree is high, so that product compactness height, any surface finish, clear-cut, size is accurate.
One kind, which vacuumizes, penetrates sand structure, and technical solution is such：It includes the mold for penetrating a device, lower part on top
Structure, the mould structure are supported on workbench, it is characterised in that：Vacuum frame is provided with below the workbench, it is described true
The lower end of empty frames is provided with lift cylinders, and the lift cylinders can drive the vacuum frame vertically to movement, the pumping of the vacuum frame
Mouth is external in vacuum pump by telescoping tube, and the air entry of air intake towards the workbench of the vacuum frame is arranged, the suction
Port is connected to the bottom gap of the mould structure, and the bottom gap is connected to the type chamber of the mould structure.
It is further characterized by：The lower end of the center of the vacuum frame is provided with connection pedestal, the linker
The lower end of seat is fastenedly connected with the upper piston bar of lift cylinders, and the lift cylinders lifting drives vacuum frame vertically to movement；
The bottom outside of the vacuum frame is evenly equipped with guiding rod base, and the bottom of the guiding rod base is installed in guide rod
Top, for the guide rod vertically to the correspondence through hole for running through bottom plate, the guide rod ensures the vertical to steady of vacuum frame
It is mobile；
The cylinder body of the lift cylinders is installed in the bottom plate；
The position fastening of the bleeding point is equipped with seal sleeve, and the outlet of the seal sleeve exposes to the vacuum frame
Lower end surface, the lower end of the seal sleeve are set with the entrance anchor ring of the telescoping tube, the lower end outer ring surface of the seal sleeve
It is close to the inner wall of the entrance anchor ring of the telescoping tube, the outer wall of the entrance anchor ring of the telescoping tube is set with sealing compression ring, really
Protect the sealing of interface.
After adopting the structure of the invention, core shooter penetrate sand before, lift cylinders are risen so that vacuum frame rise, vacuum frame
The air intake of upper surface be close to the air entry of the workbench so that the air entry of workbench is connected to mould structure
Type chamber, core shooter be close to mould structure penetrate sand mouth after, vacuum pump start completion is vacuumized for type chamber, later vacuum pump close
It closes, the vacuum state of maintenance chamber, core shooter penetrates sand so that the type that sand enters negative pressure state is intracavitary, it is ensured that sand enters in mold
The degree of packing is high afterwards, so that product compactness height, any surface finish, clear-cut, size is accurate, when demoulding, vacuum frame declines,
Ensure the normal demoulding of mould structure.
