Abstract

The invention provides an expendable pattern for manufacturing corner fittings of a container. The expendable pattern comprises a casting latex channel, a first expendable pattern and a second expendable pattern, wherein an expendable pattern latex channel is formed on a side external wall of the first expendable pattern; a first through hole and a plurality of grooves are formed on the first expendable pattern; a second through hole and a third through hole are formed on a wall of the second expendable pattern; a plurality of connecting bumps are formed on the second expandable pattern; the grooves and the connecting bumps are in inserted joint; the expendable pattern latex channel and the casting latex channel are in glued and fixed connection; the casting latex channel is prismatic; the connection position of the grooves and the connecting bumps is provided with gummed paper which is glued and fixed with the first expendable pattern and the second expendable pattern. The process issimple; the expandable pattern has a rational pattern structure, low cost and high production efficiency; and the produced corner fittings of the container have smooth surfaces and low casting defectrate.

Description

Technical field: [0001] The invention relates to the technical field of container components and moulds, in particular to a lost mold for manufacturing container corner fittings and methods for manufacturing and using the same. Background technique: [0002] The corner fittings at each corner of the container play a key role in the lifting, handling, fixing, stacking and fastening of the container. Generally speaking, any force on the box is almost all through The corner fittings are used as the outermost edge of the box, and the corner fittings also play a role in protecting the whole box. At present, the traditional casting method of container corner fittings is to use sand casting method, that is, make the mold of container corner fittings with water glass sand, put it in the sand box, after the molten steel is poured into the mold and formed, the water glass sand is scrapped, and the water glass Sand cannot be reused. In this manufacturing method, the labor intensity of...
