Mold for container corner pieces casting technology

Abstract

The invention discloses a mold for a container corner pieces casting technology. The mold comprises upper sand shells, lower sand shells and a gating system, wherein the gating system is arranged in the middle of the upper sand shells and penetrates the upper sand shells to the lower sand shells, and the upper sand shells and the lower sand shells are encircled to form a plurality of corner piecestype containing cavities with the gating system as a central axis; the gating system comprises a straight sprue, and first sprue gatings, second sprue gatings and a casting head are arranged sequentially on the straight sprue from bottom to top, wherein the first sprue gatings correspondingly communicate with each corner piece type containing cavity in the lower sand shells, the second sprue gatings correspondingly communicate with each corner piece type containing cavity in the upper sand shells, and the casting head is used for injecting molten steel. The mold for the container corner pieces casting technology has the beneficial effects that the first sprue gatings and the second sprue gatings are formed, so that the distance and the range which the first sprue gatings and the second sprue gatings pass through feeding are increased; and meanwhile, the machining amount of the hole-free large surface is increased in an auxiliary mode, the feeding is effectively carried out on a isolated hot pot, and the hole shrinkage defect is eliminated.

Description

technical field [0001] The invention belongs to the field of sand shells of container corner fittings, and in particular relates to a mold for the casting process of container corner fittings. Background technique [0002] Container corner fittings, also known as box corners and hanging corners, are mainly used in each corner of the container and play a key role in the lifting, handling, fixing, stacking and fastening of the container. Containers are used for import and export of sea freight and domestic land transportation. Corner fittings are the main accessories on containers and are used for hoisting and bundling of containers. Due to the large temperature difference in oceans around the world and large sea turbulence, the corner fittings are in poor service conditions. The performance requirements for corner pieces are very stringent. [0003] while existing corner fittings such as figure 1 ) has the following problems: the angle of the inner cavity of the corner piec...
