Abstract

The invention relates to a novel elbow pipe fitting core assembly and a manufacturing technique thereof. The fitting core assembly is composed of a flange disc, a pipeline elbow and a pipe fitting support, wherein the pipeline elbow is sleeved by the pipe fitting support; two ends of the pipeline elbow are sleeved by the flange disc; the flange disc is made of a flange cavity formed by a flange bolt convex column sand core die and a flange bolt concave hole sand core die; the pipeline elbow is made by a left elbow shell die and a right elbow shell die; the pipe fitting support is made by a first pipeline sand core die and a second pipeline sand core die; all the dies are of coating die sand types. According to the novel elbow pipe fitting core assembly and the manufacturing technique thereof, through sand core combinations of different structures, the product quality and production efficiency are improved; the production cost is lowered and the manufacturing technical requirement on the product is reduced.

Description

technical field

[0001] The invention relates to a novel bend pipe fitting assembly core and its manufacturing process. Background technique

[0002] The existing casting and forming process of elbow pipe fittings is as follows: 1) manufacture flange presser foot elbow shell mold, flange presser foot elbow pipe core box mold, flange presser foot elbow shell mold to form the external sand mold contour of pipe fittings; The sand core is built in the pipe core box mold of the blue presser foot elbow pipe; 2) The prepared flange presser foot elbow pipe shell mold and the flange presser foot elbow pipe core box mold are used to prepare the flange presser foot elbow sand mold and the pipe respectively Sand core 3) Put the prepared pipe sand core into the sand mold of the flange presser foot elbow, close the box, cast, and post-process to form a semi-finished casting of the flange presser foot elbow. This kind of manufacturing process has high technical requirements for molding wor...
