Abstract
The invention relates to a sand lined metal mould casting brake shoe tool device and a production method thereof, and belongs to the field of sand lined metal mould casting. The sand lined metal mould casting brake shoe tool device comprises a lower casting piece and a gating system, wherein the lower casting piece and the gating system are both arranged on a mould board; the sand lined metal mould casting brake shoe tool device further comprises an upper casting piece, a single casting piece, a connection board, a loam core and a flow gate; the lower casting piece and the upper casting piece are both connected with the connection board to form the single casting piece; the loam core is arranged inside an iron mould and used for forming an inner cavity of the single casting piece, a sprue base and the lower part of a cross gate; the inner flow gate is arranged in an inner pouring gate; and one end of the flow gate is connected with the cross gate, and the other end of the flow gate is connected with the single casting piece. According to the invention, the lower casting piece and the upper casting piece are connected into a circle to form the single casting piece, the inner cavity of the single casting piece is formed by the loam core, and the production method of the sand lined metal mould casting brake shoe tool device has simple operation and high efficiency, so that the yield of the casting piece is increased, the production efficiency is improved, and the produced casting piece of the brake shoe is smooth and clean in surface and accurate in size.
Description
technical field [0001] The invention relates to a casting tooling device and a production method, in particular to a tooling device and a production method for an iron mold sand-coated casting brake shoe, which belongs to the field of iron mold sand-coated casting. Background technique [0002] Iron mold sand-covered casting is one of the special castings. With the development of my country's automobile industry, it is more and more widely used. The current technology is to use green sand casting, using one mold and two pieces, and the process yield rate is 60-70%. , the production cost is high, the production efficiency is low, and the surface quality of the formed casting is not smooth, which cannot meet the existing technical requirements. [0003] Chinese Patent No. CN201110190494.0 discloses an invention patent titled "a precision casting process for green sand vacuum sealing molding". This patent uses green sand as the molding material, and reduces the number of sand c...
