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

Embodiment Construction

[0014] A pattern holder for casting moulding, such as figure 1 As shown: it includes a square cushion block 3 with one end high and the other end low. The lower end of the square cushion block 3 is matched with a main body bracket 1 through a fastening pin 2 connected with the pattern 7.

[0015] Such as figure 2 As shown: the main body bracket 1 is assembled by a base 4 that is matched with the lower end of the square block 3 and has the same shape, an upper square top 5 and a rod 6 connecting the two.

[0016] The square block 3 is a rectangular parallelepiped.

Technical field [0001] The invention relates to a pattern fixing device in the casting process, in particular to a pattern fixing frame for casting moulding. Background technique [0002] At present, in the casting process of large-scale steel castings, most of the patterns need to be turned over. Therefore, a sand bed needs to be prepared during the molding process to ensure that the patterns will not loosen or fall off during the casting process, which affects the size of the mold. The traditional modeling process has the following shortcomings: 1) Special tooling is required before modeling: modeling cast iron bottom plate, different types of scrapers and sand box size match, increasing the cost of modeling tooling; 2) before modeling, the operator needs to lay the modeling bottom plate, Sand filling and leveling to prepare a 50mm thick sand bed. Reduced production efficiency and increased production costs; 3) In the molding process, the casting mold that needs to be turned o...
