Summary of the invention
The utility model is difficult to handle at present miniature parts aperture place burr and processing cost drops into highly, and time-consuming problem such as take a lot of work provides a kind of micro parts die casting.During this mould has solved simultaneously and has produced after the micro parts die casting, the problem that cinder ladle and part are difficult to separate.
The utility model is in order to overcome the above problems, a kind of micro parts die casting is provided, comprise front mould, back mould, slide block, described front mould is provided with interior hole forming hole, device has interior hole forming pin in the interior hole forming hole, described slide block is provided with row position pin, and interference fit between described interior hole forming pin and the row position pin.Owing to change the matched in clearance between interior hole forming pin and the row position pin into interference fit, so can effectively prevent the formation of burr, overlap, burr.Usually the matched in clearance that adopts in the prior art is owing to exist the gap, so be easy to form burr in slit place's moulding after molten metal flows into, this situation is more easy when mould has relative slip.Formed burr so can constantly enlarge, has had a strong impact on the quality of product again because lever principle, increases the operation of deburring after the die casting program, and not only time-consuming taking a lot of work, and deburring equipment cost height have increased the production cost input of part.Adopt the miniature die casting in the utility model, because there is not the slit between interior hole forming pin and the row position pin, thus be not easy to produce burr, thus not only guaranteed the quality of product, and need not to carry out follow-up deburring operation, saved the great amount of manpower and material resources investment.
As a kind of improvement of the present utility model, interference is 0.002 centimetre between described interior hole forming pin and the row position pin.Though adopt interference fit can effectively avoid the formation of burr, overlap, cloak between interior hole forming pin and the row position pin, if but interference is excessive, die can't be adjacent to by matched moulds before and after the die casting, thereby cause part die joint overlap, even whole die joint " pancake " phenomenon, fly material simultaneously and be very easy to hurt the workman, so on the basis of taking all factors into consideration, through continuous experimental study, determine that interference fit best between interior hole forming pin and the row position pin is of a size of 0.002 millimeter.
As another kind of improvement the of the present utility model, on front mould, be provided with connectivity slot, described connectivity slot is integral body with the series connection of the interior hole forming hole on the front mould.Since this connectivity slot with the interior hole forming hole on front mould series connection for whole, so after die casting, formed cinder ladle is connected as a wholely in interior hole forming hole, is very easy to it is screened, and separates with part.Compare with the technology of a present cinder ladle of an existing part,,, saved human resources greatly so do not need a large amount of workmans to carry out manual screening owing to can be used as whole screened, separation.Separate the cinder ladle that obtains and also can go into stove again, utilize once more, thereby saved production cost.
In sum, the beneficial effects of the utility model are conspicuous.Guarantee that not only product is not easy to produce burr, overlap, burr etc. in press casting procedure, and make that cinder ladle is easy to separate with part after the die casting.Reduce production process, saved investment in human resources, reduced production cost.
