The utility model relates to a heat -insulating shield built -in appliance of different weight steel ingots of same ingot mould pouring belongs to metallurgical industry casting equipment technical field. Technical scheme is: contain eye (3) and nail at the bottom of heat -insulating shield (1), ingot mould (2), the ingot mould, the cross section of ingot mould (2) is rectangle, and the upper end of ingot mould (2) is the opening type, and the lower extreme of ingot mould (2) is equipped with at the bottom of the ingot mould eye (3), heat -insulating shield (1) through the nail nail in ingot mould (2), heat -insulating shield (1) be with ingot mould (2) matched with rectangle. The beneficial effects of the utility model are that: can carry out the ingot shape at any time and match according to contract requirement, reduce on -the -spot ingot mould specification, improve the encashment ratio of many specifications small batch volume contract. The mode is nimble, and it is not enough to compensate the ingot shape, practices thrift new ingot shape development expense, reduces the ingot mould design cycle, and annual accumulative total reduces by ten thousand yuan ingot mould stock occupied funds 1200.
