The invention provides a resin sand mould. According to the technical scheme, the resin sand mould comprises an upper mould box, a lower mould box, resin sand, a cavity formed in the resin sand and a runner for communicating the cavity with the outside, wherein the resin sand is internally provided with rigid filling materials. According to the resin sand mould, the resin sand layer is internally provided with the rigid filling materials so that the use amount of the resin sand is greatly reduced under the condition that a casting is not influenced; the rigid filling materials can be repeatedly and circularly utilized so that the cost is greatly reduced; and furthermore, the use amount of the materials is reduced by adopting a hollow steel ball so that the cost is reduced.
Description
technical field [0001] The invention relates to the field of casting, in particular to a resin sand mold. Background technique [0002] In resin sand molding, since the ratio of castings and resin sand to iron sand in the mold reaches 1:10, the amount of molding resin is particularly large and the cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is: in the molding process of the resin sand mold, the amount of resin used is large and the cost is high, and a low-cost resin sand mold is provided. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a resin sand mold, comprising an upper mold box, a lower mold box, resin sand, a mold cavity formed inside the resin sand and a flow channel connecting the mold cavity and the outside world; Rigid filling material is set in the above resin sand. [0005] Preferably, in order to ensure the structura...
