Embodiment

About aforementioned and other technology contents, feature and effect of the present utility model, in the middle of coordinating below and describing in detail with reference to the embodiment of accompanying drawing, can clearly present.

Refer to Fig. 3, according to the conformability structure of the thin type radiation fan fan frame of the utility model one mode of execution comprise in metal base plate 100, bearing 200, plastic cement, manage 300 with plastic cement runner barricade 400.

Metal base plate 100 has the annular bearing part 110 and the peripheral multiple joining holes 120 that are adjacent to this annular bearing part that are positioned at its central position.

Bearing 200 is for being for example oil containing powder bearing, it has ring body 210, ring body 210 center has axis hole 220, and ring body 210 have be positioned at relatively to bottom 211 and tip portion 212, wherein, bottom 211 is resisted against the annular bearing part 110 of

metal base plate

100, and 212 of tip portion have consecutive stretched section 213 and tiltedly take on section 214.

In plastic cement, manage 300 integrated filling in multiple joining holes 120 of metal base plate 100 periphery of wrapping the ring body 210 that is fixed in bearing 200.Plastic cement runner barricade 400 is the integrated periphery that is incorporated into metal base plate 100 also.The stretched section 213 of bearing 200 ring body 210 peripheries and the oblique tortuous configuration of shoulder section 214, can promote in plastic cement, manage 300 and bearing 200 between combination soundness.In addition, because the bottom 211 of bearing 200 is resisted against the annular bearing part 110 of metal base plate 100, therefore can prevent that bearing 200 from coming off from bottom direction; Moreover, because the tip portion 212 of bearing 200 has oblique shoulder section 214, and be subject to manage 300 Bao Gu in plastic cement, therefore can prevent that bearing 200 from coming off from top orientation.

Fan the conformability structure of frame according to the thin type radiation fan of the utility model one mode of execution, in its plastic cement, manage 300 integrated filling in multiple joining holes 120 of metal base plate 100 peripheries of wrapping the ring body 210 that is fixed in bearing 200; Plastic cement runner barricade 400 is the integrated periphery that is incorporated into metal base plate 100 also.Reach according to this in metal base plate, bearing, plastic cement the structure of the integrated conformability combination of pipe and plastic cement runner barricade, combination between its each element is firm and precisely.

Refer to Fig. 4 and Fig. 5, it is respectively mfg. moulding die schematic diagram and manufacturing flow chart according to the conformability structure of the thin type radiation fan fan frame of the utility model one mode of execution, manufacture the step of this conformability structure in order to explanation, its manufacturing step is: (one), preparation metal base plate 100, and this metal base plate has multiple joining holes 120 (S1); (2), prepare bearing 200, the tip portion 212 of this bearing has consecutive stretched section 213 and oblique shoulder section 214 (S2); (3), prepare mould 500, this mould has adjacent metal base plate holding part 510, bearing holding part 520 and middle pipe injection molding room 530, and has runner barricade injection molding room 540 (S3); (4), metal base plate 100 and bearing 200 are placed in respectively to the metal base plate holding part 510 and bearing holding part 520 (S4) of mould 500; (5), the plastic cement of melting is poured into middle pipe injection molding room 530 and runner barricade injection molding room 540 (S5) of mould 500; (6), after the plastic cement of melting solidifies, by mould 500 demouldings, this plastic cement solidifying form respectively in plastic cement, manage 300 with plastic cement runner barricade 400, in this plastic cement, pipe is filled in multiple joining holes 120 of metal base plate 100 and is also wrapped the periphery that is fixed in bearing 200, this plastic cement runner barricade 400 is incorporated into the periphery of metal base plate 100, forms the fan frame (S6) of radiation fan.

Therefore, in plastic cement, manage 300 and when the plastic rubber ejaculate molding of plastic cement runner barricade 400 completing, complete simultaneously in this plastic cement, manage 300 and the conformability of this plastic cement runner barricade 400 between metal base plate 100 and bearing 200 be combined, and the manufacture that completes thin type radiation fan fan frame of a conformability.Its manufacture is simple and easy, save time, equipment and the manpower of assembling, and prepared structure of fan frame is firm, improve the shortcoming of existing thin type radiation fan fan frame, and avoid existing thin type radiation fan fan frame to be press-fitted the shortcoming that assembling mode pushes because of brute force the bearing deformation producing, guarantee the accuracy of bearing, improve the quality of product.

Although the utility model with embodiment openly as above; so it is not in order to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing various variations and retouching, therefore protection domain of the present utility model is when being as the criterion depending on claims person of defining.
