Abstract
the utility model relates to an injection moulding motor vibrator belonging to the technical field of component production and manufacture for vibrating motors, and solves the problems in the prior art that the use of rare resources increases the cost of producing motor vibrators and the use of heavy W-Ni-Cu alloy increases the weight of motor vibrator products. The motor vibrator mainly comprises a W-Ni-Cu alloy body and a plastic body, wherein, the W-Ni-Cu alloy body adopts a semicolumn structure, platforms projecting in the radial direction are arranged in the middle of the horizontal plane of the W-Ni-Cu alloy body, a groove with a circular arc-shaped section is formed in the middle of the platforms, the axial center of the groove is placed on the horizontal plane of the W-Ni-Cu alloy body, a rough surface is arranged on the circumferential outer wall of the W-Ni-Cu alloy body, and the plastic body is formed on the rough surface of the circumferential outer wall of the W-Ni-Cu alloy body. Through the injection mould performed on the outer side of the W-Ni-Cu alloy body, the needed W-Ni-Cu alloy is reduced, thereby reducing the weight of the motor vibrator, as well as the manufacture cost.
Description
Technical field
The utility model relates to a kind of injection molding motor oscillator, belongs to the technical field that the vibrating motor parts are manufactured.
Background technology
Vibrating motor is widely used in small-sized electronic product fields such as mobile phone, electronic toy at present, the oscillator that wherein produces vibrating effect adopts the tungsten-nickel-copper alloy material to make substantially, because tungsten, nickel, etc. material belong to scarce resource, cost an arm and a leg, and tungsten-nickel-copper alloy exists material heavy, thereby increased motor oscillator production cost and product weight.
Summary of the invention
The purpose of this utility model provides a kind of injection molding motor oscillator, reduces the tungsten-nickel-copper alloy material use, reaches to alleviate vibrating motor weight, reduces product cost.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: this injection molding motor oscillator mainly comprises tungsten-nickel-copper alloy body and plastic body, the tungsten-nickel-copper alloy body is semi-cylindrical in configuration, its horizontal plane middle part is provided with radially protrudes platform, it is circular groove that platform central authorities are provided with the cross section, the axle center of groove places the horizontal plane of tungsten-nickel-copper alloy body, groove is used to connect motor rotor, the outer circumferential walls of tungsten-nickel-copper alloy body is provided with rough surface, injection moulding forms plastic body on the outer circumferential walls rough surface of tungsten-nickel-copper alloy body, the upper surface of plastic body is concordant with the horizontal plane of tungsten-nickel-copper alloy body, and the thickness of tungsten-nickel-copper alloy body and plastic body thickness are proportional, also will reduce the consumption of tungsten-nickel-copper alloy material except that oscillator can be connected with motor rotor is firm.The utility model reduces the utilization to tungsten-nickel-copper alloy, thereby alleviates the weight of motor oscillator by to the external injection moulding of tungsten-nickel-copper alloy, reduces cost.
As preferably, the groove of described tungsten-nickel-copper alloy body platform, the central angle of its cross section circular arc be at 240 °～300 °, is connected with the firm of motor rotor guaranteeing.
As preferably, the outer circumferential walls surface roughness of described tungsten-nickel-copper alloy body is combined closely to guarantee plastic body and tungsten-nickel-copper alloy body at V4 ~ V1.
As preferably, the ratio of the thickness of described tungsten-nickel-copper alloy body and plastic body thickness is at 8:10 ~ 15:10.
Therefore, the utlity model has and alleviate oscillator weight, reduce the characteristics of product cost.
