Description

A kind of vibration ejecting device for casting

technical field

The invention relates to the field of mold-drawing equipment for casting, in particular to a vibration mold-lifting device for casting.

Background technique

Mold removal is the operation process of taking the mold out of the sand mold, ceramic mold, etc. The mold removal requires the workers to operate very carefully. A little carelessness and improper mold removal will damage the mold. If the mold is damaged, repair it. Repairing the mold will cause a waste of time, and even the mold will be scrapped, and the shape and size of the repaired mold are not accurate, which will cause defects such as sand inclusions and pores in the casting. Especially ceramic precision casting requires high dimensional accuracy. Generally, the draft angle is very small, or even not let go, and because the casting mold is grouted and gelled with ceramic slurry, the adsorption force between the model and the slurry is very large. , resulting in difficulty in mold removal. It cannot be taken out by hand, and it is not allowed to use the method of knocking and vibration to pull out the mold. The mold is not smooth, and sometimes it will cause the breakage and damage of the part of the ceramic mold that is not easy to demould. Therefore, the process link of mold lifting has a great influence on the quality of ceramic molds. In the production of ceramic precision casting, mold lifters are indispensable tools. Therefore, a reasonable mold tool must be designed.

For small castings, generally use a lifting needle to lift the mold. For medium and large castings, since the mold is too large to be moved by people, it is necessary to use a crane to lift the mold. No matter which method is used, it is necessary to find out the center of gravity of the casting mold first. Prevent the casting mold from swinging left and right when the mold is lifted, and when the mold is lifted, it is necessary to tap the mold lightly to avoid damage to the mold. The labor intensity is high when the mold is lifted using the lifting needle, and it is difficult to ensure that the lifting force and the center of gravity of the mold are on a vertical line when the mold is lifted using a crane, which is likely to cause damage to the mold cavity, and later repairs will increase the labor load.
