Abstract

The invention belongs to the technical field of sand mould casting, and specifically discloses a casting mould frame. The casting mould frame comprises a frame body and a moulding sand layer located in the frame body, wherein a cooling pool is arranged on the frame body; a pipeline penetrating through the moulding sand layer is arranged on the frame body; the two ends of the pipeline are communicated with the cooling pool respectively; the outer wall of the pipeline located in the moulding sand layer is coated with a layer of epoxy resin; and a lead block is embedded on the wall of the pipeline. The casting mould frame disclosed by the invention has a function of accelerating cooling of liquid metals in a mould cavity.

Description

technical field [0001] The invention relates to the technical field of sand mold casting, in particular to a casting mold frame. Background technique [0002] Sand casting, a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. The outer sand molds used in sand casting are divided into three types: clay wet sand molds, clay dry sand molds and chemically hardened sand molds according to the binder used in the sand and the way to build strength. [0003] In order to accelerate the cooling speed of liquid metal in the mold frame, the usual method is to process ventilation holes on the mold frame, and during the ...
