Description
Technical field
The utility model relates to a kind of cpu fan leaf electrical bar formula injection moulding patrix, belongs to injection mold technical field.
Background technology
At present in the fan leaf productions such as CPU, conventional is exactly injection moulding, and production efficiency is fast, and the mould usually adopted, if its structure is more complicated when producing in batches, time structure is more complicated, will bring a lot of problem when designing, as: 1, the uniformity of heating; 2, steam vent distribution; 3, charging aperture distribution, if the bad qualification rate that will reduce product of the problems referred to above process.
Utility model content
For the problems referred to above, the utility model provides a kind of cpu fan leaf electrical bar formula injection moulding patrix, and its structure is simple, and easy to operate, homogeneous heating, avoids the qualification rate affecting product because heating inequality, further ensure that the qualification rate of product.
The technical scheme that the utility model is taked is:
Described cpu fan leaf electrical bar formula injection moulding patrix, comprise mould body, the lower left quarter of upper mould body has been horizontally disposed with injection channel, it is characterized in that: patrix body upper part be provided with one piece on mould body heating heated aluminum block, groove is offered downwards at the upper surface of upper mould body, the lower surface of heated aluminum block is extended with the projection with groove fit downwards, laterally a heating chamber is offered in the middle part of heated aluminum block, two ends, heating chamber left and right are all provided with electrically heated rod, injection channel madial wall is provided with the boss of circulus, boss right side is concordant with the injection channel port of export.
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 utility model brings is mainly:
By the utility model, its structure is simple, under heated aluminum block effect, the even heat of heating chamber and electrically heated rod 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 design of boss, facilitate the demoulding that injecting products is shaping, ensure that pressurize effect during Injection hold pressure simultaneously.
