Problems solved by technology
[0002] At present, the production cycle of large-scale rotary steel castings is tight. According to the normal mold production process, it is far from meeting the customer's requirements for delivery. Moreover, the production of casting molds is expensive. If only one casting is produced, the cost of the mold will account for the total value of the casting. 30% of , production profit is meager

Embodiment Construction
[0022] A method for manufacturing a large-scale rotary steel casting mold: the method includes the following processes:
[0023] a. Modeling: According to the casting drawings, analyze the NDT, dimensional tolerance and roughness requirements of the castings, and design the casting process of the castings;
[0024] b. Enter the company's mold library, select scrapped molds for comparison and analysis, and select molds that are similar in shape to the current digital model and smaller in size;
[0025] c. Comparison of digital models: compare and analyze the digital models of new molds and scrapped molds, and fit them to the best position, so that the distance between the new and old digital models can be kept even;
[0026] d. Set up the reference platform: Choose to design a reference platform for sand scraping on the relatively flat surface of the old mold. The height of the reference platform is equal to the height of the new digital model. The distance between each refere...

Abstract
The invention relates to a manufacturing method of a steel casting mould, and particularly relates to a manufacturing method of a large-scale revolved body steel casting mould. The manufacturing method is characterized by comprising the following steps: modeling, entering a company mould library, selecting a scrapped mould and carrying out comparative analysis, selecting a mould having the shape close to that of the current digital analogy and having the small volume, carrying out digital analogy comparison, setting a standard station, designing a sand scraping plate, designing a reinforcing rib, filling resin sand on the scrapped mould, scraping the sand to be horizontal by utilizing the sand scraping plate, spraying zircon power coating on a sand scraping surface for 2-3 times, and forming a shape. The method provided by the invention has the advantages that the method is unique, the production cycle of a casting is reduced, and the production cycle of the mould is saved.
Description
technical field [0001] The invention relates to a manufacturing method of a steel casting mold, in particular to a manufacturing method of a large revolving steel casting mold. Background technique [0002] At present, the production cycle of large-scale rotary steel castings is tight. According to the normal mold production process, it is far from meeting the customer's requirements for delivery. Moreover, the production of casting molds is expensive. If only one casting is produced, the cost of the mold will account for the total value of the casting. 30%, the production profit is meager. [0003] So far, there is no method for overcoming the above-mentioned defects. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art and provide a method for manufacturing a large-scale revolving steel casting mold with a unique method, which can reduce the casting production cycle and save the mold manufacturing cycle. ...
