The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of elevator traction sheave mould of the present utility model, as shown in Figure 1, described traction sheave comprises tabular body 1 and is located at continuous wheel rim 3 of described body one week of 1 edge, and described wheel rim 3 is perpendicular to body 1 plane, and body 1 central authorities are provided with axial nebenkern cylinder 5.Described mould comprises upper punching block 2 and the lower punching block 4 of moulding traction sheave outer surface, and the moulding traction sheave recess sand mo(u)ld 6 of both ends of the surface recess up and down, described upper and lower punching block 2,4 are provided with the described column inner hole sand mo(u)ld 8 of taking turns cylinder 5 inner chambers of moulding, described upper and lower punching block 2,4, recess sand mo(u)ld 6 and endoporus sand mo(u)ld 8 enclose a traction sheave molding chamber, be provided with casting liquid cast passage in the described lower punching block 4, the described forming cavity of described channel connection and mould are cast the liquid storage pool outward.Described cast passage comprises a main channel 11 and two branch roads 12 being told by described main channel 11, and described two branch roads 12 pass to respectively described forming cavity lowermost end, and along diametric two positions of forming cavity, described main channel 11 is communicated with casting liquid storage pool.The termination of described two branch roads 12 and described forming cavity bottom end face.Be provided with liquid pump 14 in the described main channel 11, will cast casting liquid in the liquid storage pool during work by in main channel 11 and two the described forming cavities of branch road 12 suction.Because the position that the forming cavity bottom links to each other with described two branch roads 12 is symmetrical about axis, can improve the uniformity that casting liquid injects.One end of described endoporus sand mo(u)ld 8 stretches out described upper punching block 2, and the other end radially is fixed in described lower punching block 4, and the threaded one end that described endoporus sand mo(u)ld 8 stretches out punching block 2 is connected with and fixedly emits 16.Described 16 bottoms that fixedly emit flush with upper punching block 2 tops, fixedly emit 16 external diameter be endoporus sand mo(u)ld 8 diameters 1.1-1.3 doubly, surpass the edge that the through hole of endoporus sand mo(u)ld 8 is set in the upper punching block 2, can when casting, block punching block 2, make whole mould more stable, but emitting fixedly sometimes that 16 external diameters are excessive may inconvenient directly Unscrew or tighten.Therefore, at the described T font torsion bar 18 that fixedly emits 16 tops to be provided with axial setting, the handled easily person rotates by this torsion bar 18 comparatively easily and fixedly emits 16.The other end of described endoporus sand mo(u)ld 8 is provided with boss 81, and lower punching block 4 upper ends are provided with the groove 41 that matches with described boss 81, and during convenient the use, endoporus sand mo(u)ld 8 is fixing this end.
During installation, be followed successively by from bottom to top the lower punching block 4 with the cast passage, endoporus sand mo(u)ld 8, recess sand mo(u)ld 6, upper punching block 2.Wherein, endoporus sand mo(u)ld boss 81 is downward, is embedded in the lower punching block groove 41, and the upper end spins and fixedly emits 16 after upper punching block 2 installs, and mould shaft is worked as to fixed stably.During moulding, the casting liquid that to cast in the liquid storage pool by liquid pump 14 is injected in the die cavity slowly, stably by the cast passage, after finishing whole modeling process, during the demoulding, screw off first and fixedly emit 16, take out successively upper punching block 2, recess sand mo(u)ld 6, traction sheave and endoporus sand mo(u)ld 8 obtain the sand mo(u)ld of traction sheave finished product and recovery.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine technical scope according to the claim scope.
