Resin sand mold

Abstract

The invention discloses a resin sand mold. The resin sand mold comprises an upper frame and a lower frame; the upper frame and the lower frame are connected by a hinge; two surfaces of the upper frame and the lower frame are hollowed; multiple flatly paved iron bars are respectively arranged on the top surface of the upper frame and the bottom surface of the lower frame; multiple circular insertion ports are formed in the side edges of the upper frame and the lower frame; through cylinders are arranged in the multiple circular insertion ports; and the cylinders and the insertion ports are connected by a movable locking mode. The resin sand mold can be filled with resin sand more tightly, and guarantees no gap between the resin and a model, so that a finally obtained finished product is not rough in surface, and has no defective goods.

Description

technical field [0001] The invention relates to the field of casting, in particular to a resin sand mold. Background technique [0002] Resin sand is an essential material in the foundry industry. It is used to fill in the mold. At that time, because the resin sand is powdery, it may stick together during use, especially when it is filled into the mold and placed with the product model. When they are together, the resin sand may not be tightly filled into the mold, and cannot be tightly filled with the model, so that there may be gaps between the resin sand and the mold or model, or there may be some small gaps, which will affect the pouring The surface smoothness of the finished product after molten iron affects the quality of the finished product. Contents of the invention [0003] The object of the present invention aims at the defect in the prior art, provides a kind of resin sand mold, and this resin sand mold can make resin sand be more compactly filled in the mould...
