Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold changing device for an injection molding machine, a die casting machine, a press machine, etc. (hereinafter referred to as a molding machine).
41.

The father's work on the mold, which also allows χl/Cp to be formed, requires a lot of time and manpower, which hinders productivity. For this reason, it has been desired to carry out the molds used in the molding machine to and from a warehouse, and then to carry out the process of carrying the molds into and out of the molding machine under central VC control, thereby automating or increasing the efficiency. Then, according to the production plan, the production amount for each mold and the mold used in each molding machine are programmed in advance, and the used mold is taken out from the molding machine and a new mold is stored in a warehouse where lines are drawn. The current challenge for development is a production system that enables molding operations to be carried out in a short period of time by transporting the product from the molding machine and attaching it to the molding machine. Nowadays, the era of mass production has come to an end, and the amount of production with a single mold is small compared to the past, so mold replacements are quite frequent, and there is a strong demand for this to be done quickly and efficiently.

An example of a conventional mold changing device will be described with reference to FIG. One of the plurality of molding machines is shown as 11, and this molding all
A main line 12 for transporting molds from a warehouse (not built) is laid along K, and an A cart 13 runs on the main line 12 as shown in FIG.

In addition, a supply line 14 is laid between the molding il> and the main line 12, and a mold (A in the figure,
A B trolley 16, which can accommodate two containers (shown as B and C) and has a preheating mechanism 15 on one side thereof, runs. In the figure, the preheating mechanism 15 is provided on the left side of the B truck 16, but it may be provided on either the left or the right.

To describe the operation of this device, when the production volume of the mold AiC in use in the molding machine 11 is finished, the mold A is carried out to the empty space on the right side of the B cart 16 as shown in Fig. 1H)Vr-. .

Next, as shown in FIG.
Transport to 1. Then, as shown in FIG.
Transfer to the left 1st rule of 6. Next, as shown in Figure 1), the A-carriage is moved to the right and the mold A is carried out from the B-carriage 16 to the A-carriage 12. When you return it to the warehouse, the first (9) (
The state of e) is shown, and the molds of molding machine 1] are from A to BK.
Instead, and B trolley 14. The mold on the left side of is changed from B to C, but its arrangement is the same as in Fig. 1(A).

In this method, as shown in Figure 1 (b) and
4 Immediately after transporting mold B, which had been placed on B trolley 161c ty and preheated on supply line B, to the molding machine 1], a new mold C was carried from the warehouse to @ place where mold B7 had been placed. Bring it in immediately for preheating. That is, since the main line 120 person trolley 13 is used in connection with the mold exchange process of the molding machine, the position of the B trolley is restricted, and molds are quickly supplied to the B trolley in a large number of molding machines. In order to do so, there would be a shortage of one A-cart. However, if there are a plurality of A carts on the main line 12, it is inconvenient when returning used molds to the warehouse. As described above, in this method, the J control as a mold exchange system is complicated.

FIG. 2 shows the other side of the conventional example, and the difference between this example and FIG. This is what we have set up. The operation of the example shown in FIG. 2 will be described.

A mold B to be used for the ash is placed in the center of the B cart 21 and is preheated by a preheating mechanism, and a mold C to be used next is placed on the left side thereof. First, as shown in Figure 2 (a), move the used mold A from the molding machine 1 to the B cart 2J.
Carry it out to an empty space. Next, as shown in FIG. 2 (b), move the B cart 21 to the right by one mold, and then mold the mold B to the mold a1.
1, and move the mold C to the central part that covers the preheating mechanism. Next, as shown in Figure 2 (-), the mold to be used next to mold C is carried from the warehouse by truck A 13 to truck B 2.
Carry it in to the left side of 1. Then, K as shown in Figure 2)
When the A-carriage 13 is moved to the 2-type partial block, the used mold A is carried out to the 2-carriage 13 and returned to the warehouse, and the B-cart is moved to the 2'-type partial block, the state shown in Fig. 2 (E) is obtained. become.

In this second example, the next mold C is placed on the B trolley 2], so new molds can be placed as quickly as in the first example.
There is no need to place it on the trolley, but A/truck 13 is +
Fi! At the same time as receiving the J rule, the control operation of the B bogie becomes complicated. Furthermore, as shown in Figure 2 (b), the roller (not shown) that rotates the mold in the center of the B-carriage 21 rotates vertically and horizontally in the figure, so a switching groove is required for this roller. This makes the mechanism complicated and increases the cost.

The present invention eliminates these drawbacks, and its purpose is to reduce the cost and increase the number of molded 8! It is an object of the present invention to provide a mold changing device for a molding machine that efficiently manages a mold changing process for a molding machine.

The present invention will be explained below based on the third factor showing one embodiment. This embodiment differs from the conventional example shown in FIG. 1 in that the distance between the main line 12 and supply line 14 is increased, and a mold loading (loading station 31) and -i4 unloading station 32 are provided between them. It is a feature.

The operation of this configuration will be explained. As shown in FIG. 3(A), 4μ IC of the mold C to be used next is placed in the loading station 31 in advance, and
Mold B, which will be used next, is placed on the left side where the preheating mechanism is located. In this down position, molding with mold A in use in molding @ 13 is completed and the product is gold! Transport uA to the right side of B truck 16. Next, the B truck 1 shown in Figure 3 (b)
6 is moved to the first mold block 1HJl, the preheated gold QB is carried into the molding box, and the used mold A is carried out to the unloading station 32. Then, as shown in FIG. 3(1), the mold C on the blowing station 31, which was overactive,
is carried into the left side of the B truck 15 which has a preheating mechanism. After this, molding machine 1] is used to mold BIF-VC (see Figure 3).
As shown in (E), new molds are transported from warehouse E by truck A 13 to the loading station 31, and used molds A from the unrope ink station 32 are returned to the warehouse by truck A 13.

The above description is based on the B trolley 1 on which two molds are placed in Fig. 1.
6 has been explained as an example, but it can also be applied to a B cart 21 on which three molds are placed as shown in FIG.
A loading station and an unloading station are installed on the front of both the left and right sides of the truck.

As described above, the mold changing device for a molding machine according to the present invention is a trolley that moves on a main line extending from a warehouse to a large number of molding machines and transports firefly molds between the warehouse and the molding machines. , a B-carriage that moves on a supply line provided in front of each molding and molding and on the side of the main line, and on which at least two molds are mounted;
It consists of two stations between the main line and the supply line for temporarily placing and holding the mold.

Accordingly, although the present invention has an extremely simple configuration in which a loading station and an unloading station are provided at the same time as the main line and the supply line, a large number of molding types can be formed at any time during molding using each mold. Machine A on the main line transports new molds from the warehouse to the loading station of each molding machine, and then returns the old molds from the unloading station to the warehouse. . The loading of new molds into the Tanu molding machine and the unloading of used molds are carried out independently from the B truck, so the degree of self-density of the B truck is high, and one machine can handle all the molds. It is now possible to carry in and out molds,
The present invention has the effect that a factory equipped with a large number of molding machines can be unmanned and automated.
