Casting mold with heat sink molding cavity

Abstract

The invention discloses a casting mold with a heat sink molding cavity. A fixed mold core is provided with a fixed mold cavity which is a rectangular groove; a circular heat sink molding boss is arranged at one side in the rectangular groove; a moving mold core is provided with a moving mold cavity; a rectangular boss is arranged in the moving mold cavity; the heat sink molding cavity is arranged on the rectangular boss; a distributor communicates with the moving mold cavity through a funnel-shaped runner; a plurality of uniformly-distributed cinder ladles are arranged at positions, which are positioned at the outer side of the moving mold cavity, in the moving mold core; exhaust grooves communicating with the cinder ladles are formed in the moving mold core and a moving mold frame; and cinder ladle grooves matched with the cinder ladles in the moving mold core are formed in the fixed mold core. The circular heat sink molding boss of the fixed mold cavity and the heat sink molding cavity of the moving mold cavity are matched to form a heat sink; and by arranging the cinder ladles and the exhaust grooves, higher effectiveness in exhausting is realized, air holes of products are reduced, and the quality of the products is improved.

Description

technical field [0001] The invention relates to the field of molds, in particular to a casting mold with a radiator molding cavity. Background technique [0002] Casting is a common processing method for metal parts, especially suitable for making rough parts with complex shapes. During manufacture, liquid metal is poured into the cavity of the mold, and solid castings can be obtained after cooling and solidification. The mold has a great influence on the quality of the casting, especially when the mold is divided into molds, the mold has a parting surface, which is easy to produce wrong box defects. If the casting also has a hole structure, it is more likely to produce deviations in shape and size , affecting the shape accuracy of the mold, thus affecting the quality of the casting. In the prior art, guide posts and guide sleeves are usually used for positioning at most, and the positioning accuracy is not high, so the casting precision is not high, especially when making...

Problems solved by technology

The mold has a great influence on the quality of the casting, especially when the mold is divided into molds, the mold has a parting surface, which is easy to produce wrong box defects. If the casting also has a hole structure, it is more likely to produce deviations in shape and size , affecting the shape accuracy of the mold, thus affecting the quality of the casting

In the prior art, guide posts and guide sleeves are usually used for positioning at most, and the positioning accuracy is not high, so the casting precision is not high, especially when making some high-precision fine products, it is easy to cause a high scrap rate
