Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically performing a series of operations for exchanging parts such as a mold and a spray head for a release agent in a die casting machine.

[0002]

2. Description of the Related Art Conventionally, with respect to a mold exchanging operation in a die casting machine, operations such as opening a mold, pulling out a tie bar, removing a mold, and mounting a mold have been individually automated. There is no example in which work is automated (ie, fully automated) so as to be performed continuously. The cause is
It is difficult to make auto-joints for cores, cooling water systems, electric systems, etc., and to unify the external dimensions of molds.
In addition to these, the lack of auto-joining of the spray head for the release agent has also been a factor that hinders the full automation of the mold changing operation.

[0003] Conventionally, the replacement work of the spray head has to rely on manual labor, so that the work efficiency is poor and a long time is required. In addition, the work in the die-clamping device of the die casting machine involves dangers as follows. That is,
For example, in the case of a large die casting machine having a mold clamping force of about 3000 tons, the weight of the spray head itself is also 80 to 1
It becomes as heavy as about 00kg. In such a case, the work is performed while the spray head is suspended by the crane, and the work posture is not preferable in addition to the work place. Further, since two people are required, extra labor is required.

[0004] As a method conceived to solve such a problem, there is a method of making a spray head into a cassette. This eliminates the need for a crane operation by dividing the spray head into cassettes each having a size of about 20 kg or less. However, it is not improved to be a two-person operation, and since a plurality of cassettes must be attached and detached, the operation time is increased.

[0005]

Although a mechanism (hydraulic cylinder) for making a stroke is formed, if the in-machine rollers 19 and 20 have a sufficient length in the axial direction of the mold clamping device, the above-described stroke mechanism is unnecessary.

Similarly, in the above embodiment, since the die clamp clamps the die in the lateral direction, it is necessary to consider the interference between the die clamp and the die when replacing the die. However, the mold clamp may be configured (attached) to clamp the mold in the vertical direction. In this case, it is not necessary to consider the interference between the mold clamp and the mold when replacing the mold. 19 and 20 do not require much length and do not need to be stroked in the axial direction of the mold clamping device.

(D) Then, the arm 32 is lowered to the spray head replacement position. (E) The second receiving stand 42 is raised to the spray head replacing position, and the correspondence between the old spray head 31 and the second receiving stand 42 is established. After the parts are mated, the clamp at the tip of the arm 32 is operated to release the clamp, and the old spray head 3
1 is removed from the arm 32 and collected on the second receiving table 42; (F) Then, the second receiving table 42 is lowered to a normal position on the slide table 45; (H) Next, the first receiving stand 41 is raised to the spray head replacement position, and a new spray head 311 for replacement is moved. After the corresponding portion of the arm 32 is engaged with the arm, the clamp at the tip of the arm 32 is actuated so that a new spray head 311 is formed.
