Example Embodiment

[0013] The technical solutions of the present invention will be described in detail below through the best embodiments, but the protection scope of the present invention is not limited to the embodiments.

[0014] A method for manufacturing a corner piece is characterized in that it comprises the following steps:

[0015] 1) Make wooden molds, use three-dimensional modeling software for three-dimensional modeling, draw out the solid model of the corner pieces, and arrange the models, use the machining center to make the arranged corner pieces models, manually polish the dead corners, and make them meet the size requirements 的木模;

[0016] 2) Modeling, using a wooden mold for sandbox modeling. When modeling, a magnet is installed in the sand body of the sand mold at the dead corner of the corner piece, and a mold parting agent is painted on the parting section;

[0017] 3) Open the sandbox, open the sandbox, take out the wooden mold, repair the defective place, close the sandbox, and wai...

Abstract

The invention discloses a corner piece manufacturing method. The manufacturing method includes the steps: performing a three-dimensional modeling by the aid of three-dimensional modeling software, drawing a solid model of a corner piece, and manufacturing a wood pattern with the corner piece and meeting size requirements by the aid of a corner piece model manufactured and arranged by a machining center; performing sandbox modeling by the wood pattern, arranging a magnet in a sand body of a sand mould at a dead corner of the corner piece when in modeling, and painting parting agents on a parting section; and opening a sandbox, trimming defective portions, closing the sandbox, pouring molten iron into the sandbox after the temperature of the molten iron is cooled to the casting temperature, and cooling the molten iron at the indoor temperature. By the aid of the manufacturing method, the corner piece structure can be effectively optimized by the aid of a solid of the corner piece manufactured by three-dimensional modeling, so that the corner piece is more suitable for molten iron casting, the number of casting dead corners is decreased, formability of the corner piece is improved, the molten iron can more rapidly flow to the dead corner as the magnet is arranged at the dead corner, incomplete casting of the dead corner is avoided, the finished product ratio is increased, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to a method for manufacturing corner fittings. Background technique [0002] The corner piece is a kind of casting, which has higher requirements on the mold when casting the hinge. The corner fittings are used to install on the eight corners of the container for hoisting and fixing the container. Some corner fittings are provided with longer lifting ears. Difficulty in casting corner fittings due to longer lifting lugs. The longer lifting lugs tend to form dead angles in the cavity of the sandbox, causing the molten steel to cool and solidify before filling the dead angles, resulting in more defective products, lower production efficiency, and indirectly increased production costs. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing corner fittings that can improve production efficiency and yield while reducing production costs. [0004] In order to realize above-...
