Casting moulding system

A casting moulding system comprises a template and a speed reducer shell model arranged on the template, wherein the speed reducer shell model is connected with a casting system; the casting system is further connected with at least one bearing cover model; and the bearing cover model is also connected with the template. By adopting the technical scheme, one casting system can simultaneously cast one speed reducer shell and two bearing covers, thus greatly improving the produce rate of craftwork. The produce rate of craftwork can be increased by about 2.4% after the bearing cover model is additionally arranged, and the capital for energy conservation and emission reduction of only one product can be saved by about ***yuan and about ***yuan annually according to the production plan of 1000 sets of the sales department in January.
