Pattern fixing rack for casting and molding

Abstract

The invention relates to a pattern fixing device in a casting process, and particularly relates to a pattern fixing rack for casting and molding. The pattern fixing device is characterized by comprising a square cushion block with one higher end and the other lower end. A main body bracket is matched at one lower end of the square cushion block through one fastening bolt connected with a pattern. The pattern fixing device provided by the invention has a specific structure; the production efficiency can be reduced; the cost is saved; and the potential safety hazards are removed.

Description

technical field [0001] The invention relates to a pattern fixing device in the casting process, in particular to a pattern fixing frame for casting molding. Background technique [0002] At present, in the casting process of large-scale steel castings, most of the patterns need to be turned over for molding. Therefore, sand beds need to be prepared during the molding process to ensure that the patterns will not loosen or fall off during the turning over process, which will affect the size of the mold. The traditional molding process has the following disadvantages: 1) Special tooling is required before molding: molding cast iron base plate, different types of scrapers match the size of the sand box, which increases the cost of molding tooling; 2) Before molding, the operator needs to lay the molding base plate, Sand filling and scraping to prepare a 50mm thick sand bed. Reduce production efficiency and increase production cost; 3) During the molding process, the casting mol...

Problems solved by technology

[0002] At present, in the casting process of large-scale steel castings, most of the shapes need to be molded by turning over the box. Therefore, a sand bed needs to be prepared during the molding process to ensure that the shape will not loosen or fall off during the turning over of the box, which will affect the size of the mold.

The traditional molding process has the following disadvantages: 1) Special tooling is required before molding: molding cast iron base plate, different types of scrapers match the size of the sand box, which increases the cost of molding tooling; 2) Before molding, the operator needs to lay the molding base plate, Sand filling and scraping to prepare a 50mm thick sand bed

Reduce production efficiency and increase production cost; 3) During the molding process, the casting mold that needs to be turned over, due to the use of the bottom plate and the preparation of a sand bed, increases the weight of the turned over box, and there is a safety risk of overweight

There is currently no device to overcome this problem
