Multi-layer combined type container corner fitting precoated sand shell mold and pouring process

Abstract

The invention discloses a multi-layer combined type container corner fitting precoated sand shell mold and a pouring process, and particularly relates to the technical field of container corner fitting precoated sand shells and pouring processes. The multi-layer combined type container corner fitting precoated sand shell mold comprises a corner fitting precoated sand shell whole body and a movable pouring cup, and the number of the layers of the precoated sand shell whole body is one to four. According to the combined type container corner fitting precoated sand shell and the pouring process, two layers, three layers, four layers and at most four layers can be arranged as a group to pour 16 corner fitting castings, the finished product efficiency of the corner fitting castings can be improved through sand shell pouring, the overall finished product efficiency of the corner fitting precoated sand shell is improved, the molten steel pouring frequency and weight are reduced, a chilling block is arranged in the sand shell in the shell manufacturing process, the distance between the sand shell and the chilling block is 3-4 mm, the chilling block is not in direct contact with molten steel in the casting process, shrinkage cavities of corner piece castings cannot be generated due to the fact that the molten steel is cooled too fast, and the problems that according to an existing container corner piece precoated sand shell and pouring process, the molten steel utilization rate is low, the finished product percent of pass is low and cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of a film-coated sand shell of a container corner fitting and a pouring process, in particular to a multi-layer combined container corner fitting film-coated sand shell shell mold and a pouring process. Background technique [0002] Due to the huge demand for containers in the modern transportation system, the manufacturing process of various parts of the container is becoming more and more mature. For the container corner parts that need to be cast, industrial batching can save a lot of cost. [0003] The production of corner fittings and corner fittings is made of coated sand technology. The corner fittings are cast in a single layer of coated sand, and the efficiency is too low. When the coated sand shell is assembled, the built-in cold iron is in direct contact with the sand shooting mold. , the built-in cold iron is too fast to cool the corner parts, and the corner parts will produce unstable shrinkage ...
