Conveniently go up the replacing of mould body, preferred described projection and offer groove upper mould body on laterally offer center line through hole on the same line respectively, a connecting rod is coated with in through hole, upper mould body and heated aluminum block link together by connecting rod, and connecting rod two ends pass respectively at upper mould body left and right sides wall.
Conveniently go up the replacing of mould body, improve replacing speed, be provided with one piece of block for preventing connecting rod from moving right on the right side of preferred described connecting rod, block is fixed on heated aluminum block right side wall.
In order to easy to operate, conservative control cost simultaneously, on the left of preferred described connecting rod, exposed junction is 300mm ~ 500mm.
The same in order to easy to operate, time saving and energy saving, conservative control cost simultaneously, preferred described connecting rod diameter is 30mm ~ 50mm.
Compared with prior art, the beneficial effect that the present invention brings is mainly:
By the present invention, its structure is simple, under heated aluminum block effect, the even heat of heating chamber is passed on upper mould body by projection, mould body thermally equivalent on it, firing rate is fast, and production efficiency is high, easy for installation, simultaneously when batch injection moulding, only need consider steam vent distribution and charging aperture distribution situation, not need the uniformity considering again to heat, facilitate Design of Dies, ensure that the qualification rate of product.Under the effect of cooling water cavity, can be the very fast upper mould body after injection formed be lowered the temperature, thus the cooling and shaping of expedite product.Under the design of boss, facilitate the demoulding that injecting products is shaping, ensure that pressurize effect during Injection hold pressure simultaneously, further increase the qualification rate of product when the demoulding.

Detailed description of the invention
Below in conjunction with drawings and Examples, set forth the present invention further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present invention.Undoubtedly, those of ordinary skill in the art can recognize, when without departing from the spirit and scope of the present invention, 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, shown in Fig. 3, for the injection moulding patrix that the band of fan leaf cools, comprise mould body 2, the right lower quadrant of upper mould body 2 has been horizontally disposed with exhaust passage 8, 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, one is provided with for steam-heated heating chamber 5 in heated aluminum block 4 inside, heated aluminum block 4 on the left of heating chamber 5 is provided with steam inlet, heated aluminum block 4 on the right side of heating chamber 5 is provided with steam (vapor) outlet, the basal surface of heating chamber 5 is the inclined plane 6 of a right low left high, laterally a cooling water cavity 7 is offered in heated aluminum block 4 below heating chamber 5, cooling water cavity 7 left end is provided with water inlet, cooling water cavity 7 right-hand member is provided with delivery port, exhaust passage 8 madial wall is provided with the boss 9 of circulus, boss 9 left side is concordant with exhaust passage 8 entrance point.
