Profile-followed insert for cleaning sand core fins, coring device and cleaning method

Abstract

The invention relates to the technical field of production of sand cores, in particular to a profile-followed insert for cleaning sand core fins, a coring device and a cleaning method of sand core fins. The profile-followed insert comprises a profile-followed cleaning part, wherein the profile-followed cleaning part is matched with external profiles or internal hollow structures of sand cores, and can remove fins on the sand cores during movement relative to the sand cores. The coring device comprises a coring tray, wherein the profile-followed insert for cleaning the sand core fins is arranged on the coring tray. The profile-followed insert for cleaning the sand core fins is mounted on the coring device; the fins on the sand cores are cleaned through the relative movement between the profile-followed cleaning part of the profile-followed insert and the sand cores in a coring process. Through the relative movement between the sand cores and the profile-followed cleaning part in the coring process, the fins on the sand cores can be cleaned while coring, manual cleaning of the fins on the sand cores one by one can be avoided, and a problem that the fins in the internal hollow structures of the sand cores cannot be cleaned when a core making center produces the sand cores can be solved.

Description

technical field [0001] The invention relates to the technical field of sand core production, in particular to a conformal insert for cleaning sand core cracks, a coring device provided with the conformal insert and a method for cleaning sand core cracks. Background technique [0002] The sand core is a solid structure with a special shape made by mixing casting sand, resin and some additives in a certain proportion. It is used to form the inner cavity, holes and parts of the casting that cannot produce sand. The core making center is a kind of efficient sand core production equipment. The sand core production unit generally includes a core making center, a coring robot, a core assembly platform, a dipping robot, etc., and can produce multiple sand cores at a time. Usually in the core making process of sand core, due to the deviation of equipment, tooling, etc., a sand core sheet will be formed on the core surface of the core box, that is, a draped seam, which is a kind of pr...
