Detailed description of the invention
Below in conjunction with drawings and Examples, set forth the utility model further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art can recognize, when not departing from spirit and scope of the present utility model, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
Embodiment one
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, for the electric heating bar type band cooling injection moulding patrix of cpu fan leaf, comprise mould body 2, the lower left quarter of upper mould body 2 has been horizontally disposed with injection channel 8, the right lower quadrant of upper mould body 2 has been horizontally disposed with exhaust passage 10, upper mould body 2 top be provided with one piece on mould body 2 heat heated aluminum block 4, groove is offered downwards at the upper surface of upper mould body 2, the lower surface of heated aluminum block 4 is extended with the projection with groove fit downwards, laterally a heating chamber 6 is offered in the middle part of heated aluminum block 4, heating chamber about 6 two ends are all provided with electrically heated rod 5, laterally a cooling water cavity 7 is offered in heated aluminum block 4 below heating chamber 6, cooling water cavity 7 left end is provided with water inlet, cooling water cavity 7 right-hand member is provided with delivery port, injection channel 8 madial wall is provided with the first boss 9 of circulus, first boss 9 right side is concordant with injection channel 8 port of export, exhaust passage 10 madial wall is provided with the second boss 11 of circulus, second boss 11 left side is concordant with exhaust passage 10 entrance point.
