Description
Technical field
The utility model belongs to the die apparatus field, particularly relates to a kind of fin casting mold for 1 meter of moulding length and above fin.
Background technology
At present, the fin casting mold of prior art all can only prepare the fin of length below 1 meter, and 1 meter and an above fin part are manually to be welded by two fin below 1 meter, but because butt welded seam is had relatively high expectations, need the later stage grinding process, make that yield rate and the production efficiency of welding are all lower, can't produce in enormous quantities, so production cost is higher; A part is by two secondary moulds in addition, and cast forms at twice, but this preparation method is higher to the required precision of mould, and it is bigger that mould prepares difficulty, and preparation cost is higher, and the yield rate when pouring into a mould simultaneously is also lower, so production cost is also higher.
The utility model content
The utility model provides the fin that a kind of yield rate is higher, production efficiency is higher and production cost is lower casting mold at above problem.
The utility model overcomes the above problems used technical scheme: a kind of a kind of fin casting mold with following structure is provided, it comprises patrix, counterdie and fin die cavity, described fin die cavity is that patrix and counterdie matched moulds form, described patrix is provided with pouring basin, being provided with running channel between described pouring basin and the fin die cavity is communicated with, being provided with ingate between described running channel and the fin die cavity is communicated with, described ingate is positioned at a side of fin die cavity length direction, the two ends of described fin die cavity length direction are respectively equipped with at least one gas bag, and described gas bag all is communicated with the fin die cavity.
After adopting above structure, compared with prior art, the utility model is because the entrance of running channel is positioned at a side of fin die cavity length direction, the two ends of fin die cavity length direction are respectively equipped with at least one gas bag, gas bag all is communicated with the fin die cavity, when cast then is set like this, aluminium liquid enters to two ends from fin die cavity middle part and flows, be equivalent to an original end and advance to water, the flowability of aluminium liquid in the fin die cavity better is not prone to too fast situation of solidifying, the mold-filling capacity of aluminium liquid is better, be not prone to pouring defect, and can realize the fin straight forming of length below 1 meter, saved welding sequence or twice pouring forming technology, make the production time shorter, yield rate improves, and then makes production efficiency higher, and production cost also just decreases.Therefore the utlity model has the characteristics that yield rate is higher, production efficiency is higher and production cost is lower.
As improvement, described gas bag is seven, and an end of described fin die cavity length direction is three, and one of them gas bag is positioned at the end, and other two gas bags are positioned at the another side of fin die cavity length direction; The other end of described fin die cavity length direction is four, and one of them gas bag is positioned at the end, also have a gas bag to be positioned at a side of fin die cavity length direction, all the other two gas bags are positioned at the another side of fin die cavity length direction, the then setting of the gas bag of this structure, make the utility model under 800 tons press, to produce, and original mould must just can be produced under 1250 tons press, equipment cost is higher, reduced the requirement of mould to production equipment, and then made that production cost of the present utility model is lower.
As further improvement, the two ends, another side of described fin die cavity length direction are equipped with an integrated exhaust piece, and the gas bag at described fin die cavity length direction two ends is communicated with each self-corresponding integrated exhaust piece respectively; Described integrated exhaust piece comprises the projection that is arranged on the patrix and the groove that matches with projection on the counterdie is set, the die joint of described projection and groove is equipped with corrugated striped, striped on the described projection and the engagement of the striped on the groove, after then integrated exhaust piece arranges, and be communicated with gas bag, make when cast, gas in the die cavity be unlikely to all to concentrate in gas bag, but discharge by integrated exhaust piece, thereby make that gas is less in the gas bag, be not prone to defectives such as foaming, and the aluminium liquid phase is to more, can play the effect of feeding preferably again, therefore can make the utility model yield rate and production efficiency further improve, and further reduce production costs.

As shown in the figure: 1, patrix, 2, counterdie, 3, the fin die cavity, 4, pouring basin, 5, running channel, 6, ingate, 7, gas bag, 8, integrated exhaust piece, 8.1, projection, 8.2, groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of fin casting mold as depicted in figs. 1 and 2, it comprises patrix 1, counterdie 2 and fin die cavity 3(also comprise other parts certainly, but owing to do not relate to the inventive point of the invention, so do not repeat them here), described fin die cavity 3 forms for patrix 1 and counterdie 2 matched moulds, described patrix 1 is provided with pouring basin 4, being provided with running channel 5 between described pouring basin 4 and the fin die cavity 3 is communicated with, it is characterized in that: be provided with ingate 6 between described running channel 5 and the fin die cavity 3 and be communicated with, described ingate 6 is positioned at a side of fin die cavity 3 length directions, the two ends of described fin die cavity 3 length directions are respectively equipped with at least one gas bag 7, and described gas bag 7 all is communicated with fin die cavity 3.
Described gas bag 7 is seven, one end of described fin die cavity 3 length directions is three, and one of them gas bag 7 is positioned at the end, other two gas bags 7 are positioned at the another side of fin die cavity 3 length directions, also can be regarded as on the die cavity wall of an end end that a gas bag 7 in three gas bags 7 is positioned at fin die cavity 3 length directions, remain two gas bags 7 and be positioned near the die cavity wall of the side that is away from running channel 5 the end end of fin die cavity 3 length directions; The other end of described fin die cavity 3 length directions is four, and one of them gas bag 7 is positioned at the end, also have a gas bag 7 to be positioned at a side of fin die cavity 3 length directions, all the other two gas bags 7 are positioned at the another side of fin die cavity 3 length directions, also can be regarded as on the die cavity wall of other end end that a gas bag 7 in four gas bags 7 is positioned at fin die cavity 3 length directions, also have a gas bag 7 to be positioned near the die cavity wall of the side that is communicated with running channel 5 other end end of fin die cavity 3 length directions, remain two gas bags 7 and be positioned near the die cavity wall of the side that is away from running channel 5 other end end of fin die cavity 3 length directions; Gas bag 7 makes that aluminium liquid can squeeze the gas in the fin die cavity 3 in the gas bag 7 when cast, prevents pouring defect, the yield rate when increasing moulding.
