Super-large iron type sand coating molding machine device and molding method thereof

Abstract

The invention relates to a super-large iron type sand coating molding machine device and a molding method thereof, and belongs to machinery. The super-large iron type sand coating molding machine device comprises a sand shooting and coating mechanism, a mold closing and lifting molding trolley, a trolley moving linear track, an upper beam, an upright column and a base; the sand shooting and covering mechanism is fixed to the upper beam; the upper beam is connected with the base through the upright column; the trolley moving linear track is fixedly mounted on the base; and the trolley moving linear track is used for back-and-forth movement of the mold closing and lifting molding trolley. The invention also provides a molding method of a molding machine. The super-large iron type sand coating molding machine device is simple and reasonable in structural design and is safe and reliable, mold closing, mold lifting, sand shooting and sand coating processes operate stably, the labor intensity in operation is low, a hanging and molding station of an iron mold is convenient, a mold is convenient to clean, and the use requirements are met.

Description

technical field [0001] The invention relates to a device and a method, in particular to a super-large iron sand-coated molding machine device and a molding method thereof, which are applied to sand-coated super-large iron molds and belong to machinery. Background technique [0002] Iron mold sand-covered casting belongs to special casting. Its mold is formed by covering a thin layer of coated sand on the inner cavity of the metal mold; iron mold sand-coated casting has the advantages of energy saving, material saving, high efficiency, high quality, green production, etc. Features, the application field is more and more extensive. [0003] For most mass-produced castings, mechanized iron mold sand-covered casting production lines are generally used to organize production; but for some castings with small batches and particularly large castings, it is difficult to organize production in the above-mentioned way. For these castings, iron molds are produced by sand-covered casti...

AI Technical Summary

Problems solved by technology

Although the entire conveying and processing uses a set of roller table, the cost is low, but it is not suitable for castings with particularly large castings. Due to the large volume and weight of the iron mold, the weight of a single iron mold generally exceeds 4-6 tons. , the size is generally 3000-6000X1200-1800 mm, it is difficult to use the roller conveying method to convey the iron mold, so the patented roller conveying method is not suitable for sand-covered sand injection molding of large iron molds
