Abstract
The invention discloses a chiller positioning method in casting production, which comprises the steps of marking the specific placement position of a chiller on a mold in the mold manufacturing process, finding out the central point of the chiller placement position according to the size of the chiller, drilling a hole at the central point by using a drilling machine, wherein the hole depth is 20-30mm, the hole diameter is 10-20mm, embedding equal-diameter and equal-length magnetic bars in the drilled hole, and finally adsorbing the chiller at the hole opening of the drilled hole by using the magnetism of the magnetic bars. The positioning method provided by the invention can ensure that the chilling block can be placed on the mold in the molding process, the sand is planted for molding after the accurate placement position is ensured, the accurate placement position of the chilling block can be effectively ensured, and the due effect is achieved.
Description
Technical Field
The invention relates to the field of casting production of sand casting, in particular to a chill positioning method in casting production.
Background
In the existing molding process of sand casting, a mold, a chill, a sand box and molding sand need to be used, before molding, the mold is firstly placed on a flat plate, then a dead head, the chill, a pre-embedded core and the like are firstly placed on the mold, and then the sand is planted for molding. In the molding process, due to the structural problem of castings, the chilling blocks are often required to be placed on uneven irregular surfaces and are difficult to fix, and the chilling blocks are easy to shift in the sand planting process. The chiller cannot play the due effect due to chiller displacement, so that casting defects are generated on the casting, or the appearance of the casting is influenced due to the fact that the surface of the casting is raised due to the fact that the chiller cannot be placed in place.
Disclosure of Invention
The invention aims to provide a method for positioning a chilling block in casting production, which aims to solve the problems in the background technology.
In order to solve the technical problems, the invention adopts the technical scheme that:
a method for positioning a chilling block in casting production comprises the steps of marking a specific placing position of the chilling block on a mold in the mold manufacturing process, finding out a central point of the placing position of the chilling block according to the size of the chilling block, drilling a hole at the central point by using a drilling machine, embedding magnetic rods with equal diameter and equal length in the hole, and finally adsorbing the chilling block at the hole opening of the hole by using the magnetism of the magnetic rods.
Furthermore, the magnetic rod is in clearance fit with the drill hole and is stuck in the drill hole through glue.
Further, the magnetic rod and the drill hole are in interference fit.
Further, the axial section of the magnetic rod is smaller than or equal to the size of the chilling block.
The invention has the beneficial effects that:
the invention provides a chill positioning method in casting production, which can ensure that a chill can be placed on a mold in the molding process, the sand molding can be carried out after the accurate placement position is ensured, the accurate placement position of the chill can be effectively ensured, and the due effect is achieved.

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a chill positioning method in casting production, which comprises the steps of marking the specific placing position of a chill on a mould in the mould manufacturing process, finding out the central point of the placing position of the chill according to the size of the chill, drilling a hole at the central point by using a drilling machine, wherein the hole depth is 20-30mm, the hole diameter is 10-20mm, embedding equal-diameter and equal-length magnetic bars in the drilled hole, and finally adsorbing the chill by using the magnetism of the magnetic bars at the hole opening of the drilled hole.
The magnetic rod can adopt clearance fit with the drilling hole and is stuck in the drilling hole through glue, and the magnetic rod can also adopt interference fit with the drilling hole.
The axial section of the magnetic rod is smaller than or equal to the size of the chilling block.
Fig. 1 is a schematic structural diagram of a chiller after being positioned on a mold, and the chiller is positioned on the mold under the adsorption of a magnetic rod, so that even if the inclined surface or the uneven surface of the placing position of the chiller is provided, the positioning of the chiller is not influenced by the inclined surface or the uneven surface.
The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
