Description

TECHNICAL FIELD The present invention relates to a mold loading / unloading device for molding equipment that uses a mold.

(Prior art and its problems) In a molding facility using a mold, a plurality of stockers for storing the mold are generally provided in the vicinity of the molding machine to reduce the labor for changing the mold setup. There is. And
To abolish the crane suspension when changing the mold setup,
As disclosed in Japanese Utility Model Laid-Open No. 59-110615, it has been proposed to dispose a setup carriage that connects a molding machine and a stocker, and to perform a setup change through this setup carriage. There is. On the other hand, as disclosed in Japanese Patent Laid-Open No. 55-67428, a setup carriage is provided with a mold loading / unloading means, and the mold loading / unloading means can transfer the mold to / from a molding machine. Are known.

If the technology for providing the mold loading and unloading means to the set-up cart is extended to the transfer of molds to and from the stocker, a series of set-up change operations can be fully automated, and the metal can be changed for each stocker. There is an advantage that it is not necessary to provide a mold loading / unloading means.

By the way, a constant maintenance work space is required around the molding machine. Therefore, in practice, the setup carriage must be arranged with a space from the molding machine. On the other hand, in relation to the stocker, the setup cart may be arranged adjacent to the stocker.

Therefore, when the die loading / unloading means provided on the setup cart is used to deliver the die to both the stocker and the molding machine, the distance between the die loading / unloading means and the molding machine is large. In consideration of the above, the mold must be designed so that it can be carried in and out far away, which naturally causes a problem of large size and weight.

Therefore, an object of the present invention is to provide a mold loading / unloading device for a molding facility using a mold in which the mold loading / unloading means to be mounted on the setup cart can be made as small and lightweight as possible.

(Means and Actions for Solving Problems) According to the present invention, in order to achieve the above-mentioned technical problems, a mold loading / unloading means is provided on the molding machine side as well, and a molding machine and a setup carriage are provided. The delivery of the mold between them is performed by the mold loading / unloading means provided in the molding machine.

Specifically, a setup carriage that runs between a stocker for storing the mold and the molding machine is provided, and the mold is designed to be changed through the setup carriage. Assuming the molding equipment to be used, a trolley-side loading / unloading means provided on the setup trolley and used for delivery of a mold between the setup trolley and the stocker, and provided on the molding machine, the molding machine, And a molding machine side loading / unloading means used for delivery of a mold to / from the setup carriage.

By doing so, the mold loading / unloading means (bogie side loading / unloading means) to be mounted on the setup trolley may be designed in relation to the stocker to which the setup trolley can be arranged adjacently. The size and weight can be reduced.

The mold M between 0 and 0 is transferred.

Change of mold setup Centralized control panel U to preliminary temperature control panel U-1, bogie control panel U
A setup change signal is output to -2, and a series of setup work is started.

First, the setup carriage 10 moves to the stocker 6 which stores the mold M (hereinafter referred to as a new mold) that is newly set in the molding machine 15, and is mounted on the setup carriage 10. Hooker
By 108, the new mold M is transferred from the stocker 6 to the table 106 of the setup carriage 10. In addition, the stocker 6
A transfer roller (not shown) is rotatably disposed on the floor surface, and when the mold M is transferred between the setup carriage 10 and the stocker 6, the mold M moves above the transfer roller. It is supposed to be movable.

Next, the setup carriage 10 conveys the new mold M to the preliminary temperature control station 4, and again, the new mold M is moved to the preliminary temperature control station 4 by the hooker 108 mounted on the setup carriage 10.
It is set inside and preheated at this preliminary temperature control station 4.

When the preheating of the new mold M is completed, the new mold M is transferred from the preliminary temperature control station 4 to the set-up car 10 again by the hooker 108 mounted on the set-up car 10 to the molding machine 15. Be transported.

When the setup carriage 10 arrives at the molding machine 15, the molding machine 15
A mold M (hereinafter, referred to as an old mold) in the molding machine 15 is pushed out to the vacant table 106 of the setup carriage 10 by a hook 162 attached to the. After the old mold is loaded on the table 106, the table 106 moves on the setup carriage 10 to prepare for setting the new mold M on the molding machine 15. After that, the new mold M loaded on the table 106
Is drawn into the molding machine 15 by the hook 162 attached to the molding machine 15 and set in the molding machine 15.
This completes a series of setup changes.

The old mold M loaded on the setup carriage 10 is transported by the setup carriage 10 and stored in the vacant stocker 6,
Alternatively, when maintenance is required, the molding machine is transferred from the automatic operation area C to the mold tool maintenance area A.

Transfer of mold between mold tool maintenance area A and automatic molding machine operation area C When the maintenance of the old mold is required, the old mold M is
It is conveyed to the reversing machine 30 by the setup carriage 10.

The transfer of the old mold M from the setup carriage 10 to the reversing machine 30 is performed by the cooperation of the hooker 108 mounted on the setup carriage 10 and the rotational drive of the long roller 318 of the reversing machine 30. It At this time, the reversing machine 30 receives the old mold M according to whether the mold requiring maintenance is the fixed mold Ma or the movable mold Mb, and the mold supporting surface 314. Is preselected and before the old die M is received, the die support surface 314
Is set.

In the reversing machine 30, the old mold M received from the setup carriage 10 in a side-by-side state is reversed by 90 degrees to change the posture so that the fixed mold Ma and the movable metal Mb are up and down. It After the posture is changed, the old mold M, which requires maintenance, is positioned above.

After the posture is changed by the reversing machine 30 as described above, the old die M is transferred from the reversing machine 30 to the carrier vehicle 20 by the reversing machine.
This is performed by rotationally driving the long roller 318 of 30 and the roller 201 of the carriage 20. Old mold M placed on the carrier 20
Is transported to the crane yard D by the transport carriage 20 and subjected to necessary maintenance.

Mold M after maintenance is completed
The case of transporting to is the reverse of the above case, and therefore its description is omitted.

(Effects of the Invention) As is clear from the above description, according to the present invention, the die loading / unloading means to be mounted on the setup trolley may be designed in relation to the stocker. The size and weight can be reduced. As a result, the setup carriage can be prevented from becoming heavy, and the carriage can be moved easily.
