Embodiment Construction

[0029] 1. A molding method for conical castings, such as figure 1 , 2 , 3, 4, 5, 6, and 7: the method comprises the steps:

[0030] a. Place the lower half pattern 4 upside down in the sand box, adjust the position, and pour molding sand into the sand box to prepare the lower half sand mold 1;

[0031] b. After the molding sand is hardened, turn over the lower half sand mold 1 and the lower half pattern 4;

[0032] c. Place the upper half pattern 5 on the lower half pattern 4, adjust the position, and prepare the upper half sand mold 3;

[0033] d. After the molding sand is hardened, the upper half of the sand mold 3 is raised, and the upper half of the pattern 5 and the lower half of the pattern 4 are taken out;

[0034] e. Preparation of sand core 2: pour molding sand into the core box 6 and scrape it flat; take out sand core 2-a after the molding sand is hardened; repeat the above operation to prepare sand core 2-b;

[0035] f. Place the prepared sand core 2 in the low...

Abstract

The invention relates to a modeling method of a casting, especially a modeling method of a conical casting. The modeling method is characterized in that the method comprises the steps of inverting a bottom half mold in a sand box, adjusting the bottom half mold, and pouring molding sand into the sand box to prepare a bottom half sand mold; overturning the bottom half sand mold and the bottom half mold after the molding sand hardening; placing a top half mold on the bottom half mold, adjusting the top half mold, and preparing a top half sand mold; lifting the top half sand mold and taking out the top half mold and the bottom half mold after the molding sand hardening; preparing a sand core; putting the prepared sand core in the bottom half sand mold, and adjusting and fixing the sand core; putting the top half sand mold on the bottom half sand mold and finishing modeling. The modeling method provided by the invention has the advantages of being unique and solving the problems that operation is difficult, working intensity is high and model size is inaccurate in conical product modeling.

Description

technical field [0001] The invention relates to a molding method of a casting, in particular to a molding method of a conical casting. Background technique [0002] At present, cone-shaped products are usually molded by core assembly in the sand casting process. The specific method is that the outer cavity of the molding sand is formed by a pattern, and the inner cavity is formed by a sand core. The core-making method is also traditional vertical sand filling. This type of conical sand core During the preparation process, there are certain defects: 1) There are a large number of C-shaped parts and rounded parts in the inner cavity of the core box. These parts have small openings, and it is difficult to fill sand in the vertical sand filling method, and it is difficult to compact, resulting in damage to the sand mold. The quality cannot meet the molding requirements; 2) When the height of the sand core exceeds 2000mm, it is difficult for the operator to observe and operate du...
