Description
Technical field
The utility model belongs to the casting field of auto parts and components, is specially a kind of casting mould of automobile air-conditioning compressor cylinder bodies.
Background technology
Automobile air conditioner compressor is the core component of air-conditioning system, and cylinder body is the critical piece of automobile air conditioner compressor.Cylinder body is high temperature resistant, corrosion-resistant and high-strength wearable.In prior art, conventionally adopt casting technique to carry out the shaping processing of automobile air-conditioning compressor cylinder bodies.Casting is the under high pressure machine-tooled method of solidification forming of molten metal, and gained mechanical castings is good, meets the requirement of high temperature resistant, corrosion-resistant and high-strength wearable.
But because cylinder body belongs to thin-walled tubular elements, 2～3 millimeters of average wall thicknesses, and shape elongated (corresponding casting mould die cavity is darker), therefore embrace mould tight, required demoulding ejecting force is large.Conventional cast mold releasability power of the prior art is less, and forced demoulding easily damages foundry goods.In addition, existing casting mould is not generally considered molten metal shunting and flow control etc., usually cause molten metal in die cavity local accumulation, flow smooth and fill not goodly, cause moulding cylinder block casting generation shrinkage cavity, pore, defects i.e.cracks, product rejection rate is high, and production cost is large.
Utility model content
The utility model provides a kind of casting mould of automobile air-conditioning compressor cylinder bodies, and the demoulding is easy, and casting forming is good, and shrinkage cavity, pore, crack defect are few, and product yield is high, has reduced production cost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of casting mould of automobile air-conditioning compressor cylinder bodies, comprises that cover half core, moving-mould-core, first are inserted, second inserted, the first core-pulling mechanism, the second core-pulling mechanism and runner system; The die cavity that described cover half core and moving-mould-core are combined to form coordinates with cast product profile; Described first inserts inserts and is arranged in that die cavity and die cavity are movable to be coordinated with second, described the first core-pulling mechanism connects first and inserts, in order to insert and to eject from die cavity first, described the second core-pulling mechanism connects second to be inserted, in order to insert and to eject from die cavity second; Described runner system comprises around the ring gate of die cavity and is distributed on some sprues in die cavity outside, and described ring gate is all communicated with die cavity through oblique cast gate with some sprues; Described die cavity outside is also evenly equipped with some cooling water pipes, and this cooling water pipe is communicated with die cavity, and the import of cooling water pipe is all opened on cover half core with outlet.
Further, the gradient of described oblique cast gate is 45 °.
Further, offer a shaped form running channel on described cover half core, described ring gate is communicated with cast metal liquid material cylinder through this shaped form running channel.
Further, described the first core-pulling mechanism and the second core-pulling mechanism are hydraulic core pulling mechanism.
The beneficial effects of the utility model: when casting and pouring, molten metal enters die cavity through ring gate, the some sprues that are distributed on die cavity outside and oblique cast gate from barrel, cylinder body has circular end surface, ring gate can be realized annular cast to die cavity, and many sprues coordinate, make cast more even, avoid molten metal local accumulation in die cavity.When the demoulding, first the first core-pulling mechanism is inserted and is ejected from die cavity first, make again the second core-pulling mechanism insert and eject from die cavity second, core-pulling mechanism can guarantee the accurate of motion that loose core, also can avoid running material on-the-spot, and enclasping force reduces greatly after loosing core, can easily foundry goods be ejected from cover half core.Tiltedly cast gate can avoid molten metal directly to wash away cover half core and moving-mould-core, can effectively shunt and flow control, can make exhaust smooth and easy, reduces cylinder block casting shrinkage cavity, pore, defects i.e.cracks.The cooling water pipe being communicated with die cavity, can guarantee that mold temperature is constant controlled, can extend the service life of mould.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the casting mould embodiment of the utility model automobile air-conditioning compressor cylinder bodies;
Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.
In above accompanying drawing: 1. cover half core; 2. moving-mould-core; 3. first insert; 4. second insert; 5. the first core-pulling mechanism; 6. the second core-pulling mechanism; 7. die cavity; 8. ring gate; 9. sprue; 10. oblique cast gate; 11. cooling water pipes; 12. shaped form running channels.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Fig. 1～2, a kind of casting mould (the present embodiment is a kind of vortex type automobile air conditioner compressor cylinder body) of automobile air-conditioning compressor cylinder bodies, comprise cover half core 1, moving-mould-core 2, first insert 3, second insert 4, the first core-pulling mechanism 5, the second core-pulling mechanism 6 and runner system; The die cavity 7 that described cover half core 1 and moving-mould-core 2 are combined to form coordinates with cast product profile; Described first inserts 3 and second inserts and 4 is arranged in that die cavity 7 and die cavity 7 is movable to be coordinated, described the first core-pulling mechanism 5 connects first and inserts 3, in order to insert and 3 to eject from die cavity 7 first, described the second core-pulling mechanism 6 connects second and inserts 4, in order to insert and 4 to eject from die cavity 7 second; Described runner system comprises around the ring gate 8 of die cavity 7 and is distributed on some sprues 9 in die cavity 7 outsides, and described ring gate 8 and some sprues 9 are all communicated with die cavity 7 through oblique cast gate 10; Described die cavity 7 outsides are also evenly equipped with some cooling water pipes 11, and this cooling water pipe 11 is communicated with die cavity 7, and the import of cooling water pipe 11 is all opened on cover half core 1 with outlet.
