Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a casting mould for preventing castings from deflecting. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. A casting mold is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain the structural shape of the part. The structural shape of the part is made of other easily moldable materials in advance, and then the mold is placed in the sand mold, so that a cavity with the same structural size as the part is formed in the sand mold, and then a fluid liquid is poured into the cavity. After the liquid cools and solidifies, it can form a part with the same shape and structure as the mold. The specific steps are to lay one of the sand boxes flat, then place the mold in it, fill the sand box with sand and flatten it, flip the sand mold 180 degrees, so that the mold placed at the bottom is facing up, and the lower half of the mold is taken out to form a cavity, which is the lower sand box. The upper sand box is made in the same way, and then the two are combined to make a complete sand mold. The following problems exist in the prior art:

[0003] Because the position of the mold cannot be guaranteed when the mold is placed separately in the two existing sand boxes, the position of the printed mold groove will be offset when the mold is in different positions in the two sand boxes. After merging, the cast mold cannot be aligned, thus being scrapped and causing losses. At the same time, the existing sand boxes can only be placed manually when aligned. Once the upper and lower sand boxes are not aligned, the position of the mold printed in the two sand boxes will also be offset, which will eventually cause all subsequent casting molds to be unable to align.
