Abstract
The utility model relates to a plastic rotor used in a micro motor, in particular to a multi-pole magnet ring of the plastic rotor. The multi-pole magnet ring is provided with an external magnet ring and an internal magnet ring core which are made of the same magnetic material and are injection molded into a whole. Compared with the prior art, the utility model has the benefits of simplified the technology, no requirement for two injection moldings, integral injection molded formation, higher accuracy, saved material, small equipment investment and better work efficiency.
Description
Technical field
The utility model relates to the plastic rotor that a kind of micromachine is used, especially a kind of multi-pole magnet-ring that is used for epitrochanterian plastic rotor.
Background technology
The rotor of micromachine is because structure is small, and many uses have the plastic magnetic rotors of the multi-pole magnet-ring of plastic rotor.The magnet ring circle and the magnet ring core of the multi-pole magnet-ring of present employed plastic rotor separate, when making magnet ring, be divided into two casting cycles, elder generation's casting magnet ring circle, again the magnet ring core is cast in the magnet ring circle, there is following shortcoming in such way: complex technical process, and equipment drops into more, and error appears in precision easily.
The utility model content
The technical problems to be solved in the utility model is: the multi-pole magnet-ring that a kind of plastic rotor that can simplify technology, increase work efficiency is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of multi-pole magnet-ring of plastic rotor, have outside magnet ring circle and inner magnet ring core, and described magnet ring circle and magnet ring core are by the injection molded integrative-structure of magnetic material of the same race.
The beneficial effects of the utility model are, the utility model is compared with technology in the past, can simplify technology, does not need twice injection moulding, integrated injection molding, and precision is higher, has saved material, and equipment drops into little, and has improved operating efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Among the figure: 1. magnet ring circle, 2. magnet ring core.
Embodiment
In conjunction with the accompanying drawings 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.
The multi-pole magnet-ring of plastic rotor as depicted in figs. 1 and 2 has outside magnet ring circle 1 and inner magnet ring core 2, and magnet ring circle 1 and magnet ring core 2 are by the injection molded integrative-structure of magnetic material of the same race.
The manufacture method of the multi-pole magnet-ring of plastic rotor was earlier 1 injection moulding of magnet ring circle to be come out in the past, with mould magnet ring core 2 had been injection-moulded in the magnet ring circle 1.
Manufacture method of the present utility model only need be made an integration mold, just can simultaneously magnet ring circle 1 and 2 injection mouldings of magnet ring core be come out, and integrated injection molding so both can be simplified technology, can save cost again, increased work efficiency.
Claims (1)
1. the multi-pole magnet-ring of a plastic rotor has outside magnet ring circle (1) and inner magnet ring core (2), it is characterized in that: described magnet ring circle (1) and magnet ring core (2) are by the injection molded integrative-structure of magnetic material of the same race.
