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 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...

Examples

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.
