Abstract

The utility model discloses a two formula bronze drum casting moulds, by chassis (1), base (2), mold core (3), mould on the steel (4), loose -leaf (5), heel post (6), sideboard (7), foraminiferous mould ear (8), steel external mold (9) are constituteed. When making the core, enclose along base (2) and close two steel external mold (9) and fix through foraminiferous mould ear (8), again ready two formula bronze drum apperances edgewise board (7) put, then irritate the sand rammer in fact toward the two inside and outside chambeies on bronze drum apperance both sides, reserve sprue gate and venthole, then up overturn on the steel mould (4), open steel external mold (9), take out two formula bronze drum apperances and bronze drum roof apperance, close again on steel external mold (9) and the steel mould (4), can cast. Its process is simple, and the cost time is few, and hang down at the strong end of working, and the core is not fragile, and the core size is accurate, is fit for bronze drum or similar casting trade and uses widely.

Description

A kind of two-piece type bronze drum casting mould

Technical field

This utility model relates to a kind of casting mould, and more specifically, this utility model relates to a kind of bronze drum casting mould.

Background technology

At present, bronze drum casting adopts box moulding more, and is multi-disc external mold. Can be seen that it exists many defects from its production procedure: one is that process tedious is complicated, takies substantial amounts of labor time; Two is use upper and lower two box moulding cores, and labor intensity is big; Three be in process constantly mould turnover, molding, core is easily damaged; Four to loosen the molding sand around apperance when being molding, the easy modification of core, and core size, surface detail etc. easily lose shape, it is difficult to form the foundry goods of precision after casting. Up to the present, but without better solution.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of process is simple, spended time is few, labor intensity is low, core is hardly damaged, the two-piece type bronze drum casting mould of core precision size.

The purpose of this utility model is achieved by following technical proposals.

Fixing connection base 2 on chassis 1, fixing connection core rod 3 on base 2, the steel external molds 9 that the side plate 7 of two bronze drum external forms of coincideing with edge is chamber are enclosed along base 2 base, the junction of steel external mold 9 sets band casement ear 8; The fixing load-bearing pillar 6 that connects in the One On The Chassis appropriate location, load-bearing pillar 6 connects mould 4 on steel by loose-leaf 5.

The beneficial effects of the utility model are:

1, manufacture core process simple: enclose two steel external molds 9 along base 2, and with bolt by the hole fastening with casement ear 8, side plate 7 is made just to withstand two-piece type bronze drum mould again, form inside and outside two die cavities, then in inside and outside two die cavities, molding sand and reality of pounding are put into, when arriving end face, with scraper plate, end face is struck off, put preprepared bronze drum top board apperance, then close mould 4 on steel, put sand rammer more real, reserve sprue gate and venthole, then mould 4 on steel is up overturn, open steel external mold 9, take out top board apperance and two-piece type apperance, close mould 4 again on steel external mold 9 and steel, can cast.

2, from aforesaid operations process it can be seen that relative to other technique, it is few that this utility model manufactures core spended time, and labor intensity is low, core is hardly damaged, and core precision size is accurate.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described description.

Embodiment 1: the fixing connection base 2 on chassis 1, fixing connection core rod 3 on base 2, the steel external molds 9 that the side plate 7 of two bronze drum external forms of coincideing with edge is chamber are enclosed along base 2 base, the junction of steel external mold 9 sets band casement ear 8; The fixing load-bearing pillar 6 that connects in appropriate location on base 1, load-bearing pillar 6 connects mould 4 on steel by loose-leaf 5.

Claims

1. a two-piece type bronze drum casting mould, by chassis (1), base (2), core rod (3), mould (4) on steel, loose-leaf (5), load-bearing pillar (6), side plate (7), band casement ear (8), steel external mold (9) forms, it is characterized in that, chassis (1) upper fixing connection base (2), upper fixing connection core rod (3) of base (2), the steel external mold (9) that the side plate (7) of two bronze drum external forms of coincideing with edge is chamber is enclosed along base (2) base, the junction of steel external mold (9) sets band casement ear (8), appropriate location on chassis (1) is fixing connects load-bearing pillar (6), and load-bearing pillar (6) connects mould (4) on steel by loose-leaf (5).
