Description

Mold changing device {MOLD CHANGING APPARATUS}

In the present invention, not only can the efficient exchange work be performed through the standing transport member, but also the mold exchange work can be efficiently performed by combining and exchanging the mold through a connecting member having a variable length through a cross-link type link member. In addition, it relates to a mold exchange device that can prevent mold damage in advance.

As is well known, casting is mainly made by heating metal materials such as iron, aluminum alloy, copper, brass, etc. at a temperature higher than the melting point to make molten metal and injecting it into a mold. Accordingly, it can be classified into various types such as pressure casting, gravity casting, centrifugal casting, die casting, and reaction solid casting.

The mold used in this casting process has to be replaced by separating the mold when the shape or dimension of the molded product is changed or damaged and repairs are required.These molds become larger or heavy materials (e.g., metal, Since it is made of ceramic and cannot be exchanged with the power of a worker, it is exchanged using mechanical means (for example, a crane, a crane, a roller conveyor, etc.).

However, in the case of a small crane, it is not only cumbersome because a mold must be attached to the chain, and it takes a lot of replacement work time, and in the case of a large crane, since installation cost is high, there is a problem that it is not efficient and economical is also low.

In addition, when the replacement work is performed through a crane, it is difficult to control the position precisely because of the weight of the mold, so it is difficult to control the position precisely. There is a problem that may cause damage, and when a roller conveyor is used, equipment cost is high, and the work process is complicated, resulting in a problem of inferior work efficiency.
