Problems solved by technology

[0003] In the traditional iron mold sand-covered casting production line, since sand shooting can only be done on the top of the iron mold during sand shooting, the lower bottom plate is generally turned over by a turning machine. Combined with the upper mold to form the final clamping mold, but because the flipping needs to use two flipping machines on the production line separately, occupying the space of the circular production line, resulting in problems such as excessive production line size and low efficiency

Embodiment

[0022] Embodiment: a kind of circulation type iron formwork sand-covered production method is characterized in that, comprises the following steps:

[0023] (1) Clean the upper iron mold and the lower bottom plate, and place them on the circulation production line;

[0024] (2) Separate the upper iron mold from the lower bottom plate in the circulation production line, transport the upper iron mold to the first molding position, and shoot sand on the top of the upper iron mold through the core shooter for iron mold sand-covered molding to make the upper sand mold;

[0025] (3) The lower bottom plate is moved to the second molding position along the circular production line, and the lower sand mold is prepared in advance in the second molding position, and transferred to the lower bottom plate to make the lower sand mold;

[0026] (4) The lower sand mold is moved to the clamping area through the circulation production line, and the upper sand mold is directly clamped with the ...

Abstract

The invention discloses a circulating iron mold coated sand production method. An iron mold coated sand model used for a lower bottom plate is accomplished and transferred to the lower bottom plate so that the step of double turnover in a turnover mechanism during lower bottom plate modeling can be omitted. The turnover step after core shooting in a traditional process is omitted, precoated sand after modeling is directly placed on the lower bottom plate and then directly combined with an upper mold, the multiple turnover step of sand shooting after lower bottom plate turnover and mold recombination after another turnover is saved, and therefore production process steps of a production line can be saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of casting, in particular to a production method of sand-coated circular iron molds. Background technique [0002] In the foundry industry, sand-covered casting is a casting process in which a thin layer of sand is covered in the inner cavity of a metal mold (called an iron mold) to form a mold. Since the sand covering layer is relatively thin (4mm-8mm), it is also economically reasonable to use relatively expensive high-quality molding materials (usually phenolic resin). [0003] In the traditional iron mold sand-covered casting production line, since sand shooting can only be done on the top of the iron mold during sand shooting, the lower bottom plate is generally turned over by a turning machine. Combined with the upper mold to form the final clamping mold, but because the flipping needs to use two flipping machines on the production line, it takes up the space of the circular production line, resulting in proble...
