Abstract
The utility model discloses a mold for casting a short circuit ring of a motor rotor, comprising a central hole (1), a casting hole (2) and a positioning groove (3). The bottom surface of the positioning groove (3) is used as a reference surface (4) on which a short circuit ring groove (5) is arranged; and a step (6) is arranged on the short circuit ring groove (5). Compared with the prior art, as a casting cavity in the mold for casting the short circuit ring of the motor rotor corresponds to shape of the cross section of the short circuit ring of the motor rotor, the required shape of the short circuit ring of the motor rotor can be completed by one-time casting, the consumption of aluminum as well as the production cost can be reduced, the processing efficiency is improved, and the product quality and the market competitiveness are improved so as to meet the requirements of new technology.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to the mould that a kind of rotor short-circuited conducting sleeve of casting is used.
Background technology
Short-circuited conducting sleeve on the washing machine motor rotor generally all is to adopt a cast molding of cast-aluminum die at present, the short-circuited conducting sleeve cross section is a rectangle, and short-circuited conducting sleeve must carry out a chamfering finish turning processing to short-circuited conducting sleeve after casting is finished, consider to be worth doing to remove unnecessary aluminium, and guarantee the concentricity requirement of short-circuited conducting sleeve.Prior art is processed with engine lathe, in order to enhance productivity, enterprise has now all used the higher semi-automatic lathe of efficient instead and has processed, because semi-automatic lathe is feed processing, so the shape of short-circuited conducting sleeve is adding man-hour with semi-automatic lathe at present, allowance is too big, and working (machining) efficiency is low, also causes the waste of aluminium material.
The utility model content
Goal of the invention of the present utility model is, the mould that provides a kind of rotor short-circuited conducting sleeve of casting to use.A cast molding of short-circuited conducting sleeve on the rotor to adapt to the processing request of semi-automatic lathe, can be dwindled allowance, improve working (machining) efficiency, reduce the waste of aluminium material.
The mould that a kind of rotor short-circuited conducting sleeve of casting of the technical solution of the utility model is used comprises centre bore, tapping hole and locating slot, and the bottom surface of locating slot is a datum level, and datum level is provided with the short circuit annular groove, and the short circuit annular groove is provided with step.
Compared with prior art, casting cavity of the present utility model is custom-designed according to the cross sectional shape of rotor short-circuited conducting sleeve, make existing square-section into step-like cross section, to adapt to the processing request of semi-automatic lathe, can once cast and finish the shape of required motor rotor short-circuit ring, can improve Vehicle Processing efficient greatly, because the utility model has dwindled allowance, therefore also reduced the waste of aluminium material, to adapt to the requirement of new technology.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the utility model waters the short-circuited conducting sleeve schematic diagram that casts out;
Fig. 3 is that the utility model waters the short-circuited conducting sleeve cross sectional shape that casts out.
Being labeled as in the accompanying drawing: 1-centre bore, 2-tapping hole, 3-locating slot, 4-datum level, 5-short circuit annular groove, 6-step.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.Following embodiment is a kind of of the preferred specific embodiment of the utility model, the utility model is not done any restriction.Common variation and replacement that those skilled in the art carries out in the technical solutions of the utility model scope all should be included in the protection domain of the present utility model.
Embodiment: the mould that a kind of rotor short-circuited conducting sleeve of casting is used, as shown in Figure 1, Cast Aluminum Dies comprises centre bore 1, tapping hole 2 and locating slot 3, the bottom surface of locating slot 3 contacts and is close to datum level 4 with the iron core of rotor as datum level 4 during casting.Datum level 4 is provided with short circuit annular groove 5, and short circuit annular groove 5 is provided with step 6.Water the short-circuited conducting sleeve that casts out as shown in Figure 2 with the utility model, also water accordingly on the short-circuited conducting sleeve 7 among Fig. 2 and cast out the step corresponding with Cast Aluminum Dies 6, the cross sectional shape of short-circuited conducting sleeve 7 as shown in Figure 3.
Claims (1)
