Resin sand casting equipment and casting process

Abstract

The invention belongs to precision casting, and particularly relates to a resin sand casting equipment and casting process. The equipment comprises a conveying mechanism and a supporting mechanism mounted on the top face of the conveying mechanism. A forming mechanism is in transmission connection to the conveying mechanism. The supporting mechanism comprises a supporting plate and supporting columns fixed to the four corners of the bottom face of the supporting plate, and the bottom ends of the supporting columns are fixed to the top face of the conveying mechanism. During casting, casting parts located in upper molds and lower molds on one side can be taken out, and then a new sand box is loaded and adjusted; after casting is completed, a hydraulic cylinder drives connecting guide platesand the upper molds to reset, the conveying mechanism drives the forming mechanism to overall move, the upper molds and the lower molds prepared in advance are pushed to the position below the hydraulic cylinder, and the hydraulic cylinder carries out pressing down to achieve casting; and when the casting parts are taken out and the new sand box is loaded and adjusted, the equipment can carry outmachining and casting continuously, the equipment shutdown time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to precision casting, and in particular relates to resin sand casting equipment and a casting process. Background technique [0002] Resin sand casting acts as a barrier between the casting and the mold to achieve the purpose of anti-sticking sand. It can also effectively prevent the oxidation of high-temperature liquid metal, so that there is no chemical reaction between the mold and the high-temperature liquid metal, and it can absorb and digest Nitrogen, sulfur, carbon and other gases. [0003] The Chinese patent with the publication number CN109500358A discloses a resin sand casting equipment and casting process. When the casting is completed, it needs to be shut down, the casting is taken out, and a new sand box is hoisted to the inside of the mold for modulation, and then the mold is closed. Casting, equipment downtime is long, production efficiency is low, and cannot meet the needs of rapid production. Contents of the in...
