For achieving the above object, the technical solution of the utility model is as follows: a kind of metal shaft imbeds injection fixed structure, comprises metal axle, plastics wheel disc, stationary axle knot, thread twill, limited impression, wedge thread, anticreep section, it is characterized in that:
Described metal axle is cylindrical body, and its rear end part lathe tool processing turning has multiple limited impression and thread twill, forms wedge thread between described thread twill; Described thread twill section forms anticreep section, and described anticreep section is provided with multistage; Multiple limited impression of described metal axle and anticreep section part, imbedding injection integral molding by plastics has columniform stationary axle to tie, described stationary axle knot outside integral type ejection formation has round plastic wheel disc, described metal axle is fixedly connected on described stationary axle knot and plastic wheel disk center, and through described stationary axle knot and plastics wheel disc.
Described limited impression is arranged between described anticreep Duan Erduan and anticreep section, and described wedge thread and thread twill are being imbedded in injection joined integrally with plastics, have that biaxially oriented prevents from coming off, the effect of the anti-sliding stop of two circumferencial direction, are easy to shape simultaneously.
Described at least one side of wedge thread is set to wedge face; Described anticreep section at least arranges one section, and when described anticreep section arranges multistage, the thread twill sense of rotation in adjacent anticreep section is arranged on the contrary.
Described limited impression width is 1/3rd of described thread twill segment length; Described stationary axle knot diameter is at least two times of described metal axle diameter.
Working principle of the present utility model is: the structure being replaced traditional annular knurl processing procedure by pitch thread structure of getting on the bus at described metal axle, utilize the technology mode of car pitch thread, reach in the object strengthened in conjunction with fastening force inserting metalwork and working of plastics in jetting process; Can apply and apply (axle center is combined with plastic gear) with gear and other need to imbed the application of injection, particularly small size axle center and plastics imbed injection part, such as motorcycle handle Inner plastic magnet and the axis embedded application being emitted as two pole magnetites.
Pass through technique scheme, the beneficial effect of technical solutions of the utility model is: adopt mode at axle center car tooth to axle surface treatment, use the threading tool of conventional car tooth in general CNC, the corresponding position turning be combined with plastics at metal axle goes out oblique pitch thread and limited impression, increases the fastness imbedding injection metal and working of plastics; By carrying out surface Machining process in the mode of axle center car pitch thread, only needing use one that CNC car threading tool can be completed and processing on CNC lathe, the low price of car threading tool, it is convenient to replace; Car tooth processes speed is fast, efficiency is high, finished surface is afterburning little, and yield rate is high; Not easily occur to slide or obscission by this novel product imbedding injection.
