Abstract

PURPOSE:To decrease the number of cope boxes and to reduce an installation cost by installing mold transfer devices between a circulative mold forming line and a secondary cooling pool line and providing a cope box separator in the circulative mold forming line so that the cope box is separated and is subjected to secondary cooling if a long cooling time is needed. CONSTITUTION:A mold forming line 2 and a bottom mold forming line 3 are installed in parallel apart from each other at a prescribed space between the opposed longitudinal straight lines of a circulating mold forming line 1. Mold transfer devices 19, 20 are installed between the line 1 for the circulation between a top force and the lines 2, 3, and the secondary cooling pool line 13 adjacent thereto. A cope box separator 22 is provided in the position where the beginning end of the line 2 intersects with the line 1. The device 19 separates the cope box upon primary cooling and feeds the same to the line 13. The device 20 returns the casting mold to the line 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a circulating mold making line with a secondary cooling pool line.

Generally, after pouring, the casting is allowed to cool down in the mold for a long time in order to stabilize the material quality of the casting. However, there was a problem in that a large number of upper and T frames were required due to the long cooling pool time. On the other hand, depending on the product, after pouring,
There are some products that have no effect on stabilizing the quality of the moon even if they are broken down at an early stage, and such products need to be broken down early in order to prevent aging of the sand and increase in sand temperature. This was done to solve the problem, and for those that require additional cooling time after the primary cooling, the upper part is separated and only the T frame is sent to the secondary cooling pool line to cool for the required time. In addition, if only primary cooling is required, we would like to provide a circulating mold making line with a secondary cooling pool line that does not send the mold directly to the secondary cooling pool line, thereby reducing the number of pumps. This is the purpose.

Below, the f('1) structure of the present invention will be explained based on examples. (1) is a circulating mold making line, and the upper surface number of this circulating mold making line (1) means that the ends are connected to each other with bottles. A large number of mold carts (not shown) are movably mounted on the circulatory mold making line (2) and (3).
The upper mold forming line and the lower mold forming line are constructed in parallel with each other at a predetermined interval between the opposing linear longitudinal lines in 1), and the upper mold forming line is located at the intermediate position of the upper mold forming line (2). The machine (4) has been installed, and the soil tank molding line (
2) At the intersection of the terminal end and the circulating mold making line (1),
A frame matching device (5) and an upper mold separating device (6) are installed at the intersection of the starting end of the upper mold making line (2) and the circulating mold molding line (1), respectively. In addition, the upper molding machine (4) and the upper Azusa separation number! Between (6), there is a cleaning device (7) for cleaning the inner surface of the empty upper Azusa◇
In addition, a lower mold making machine (8) is installed at an intermediate position of the lower mold molding line (3), and a lower mold reversing device ( 9) is arranged, and at the intersection of the lower mold making line (3) terminal 1 and the circulation mold making line (1), a lower mold changing device base (10) is installed.
is installed. In addition, at the intersection of the starting end of the lower mold making line (3) and the circulation mold making line (S), a lower frame feeding device (11) is further installed.
) and the lower mold making machine (8), a frame cleaning device lower type disassembly unit Wt, (12) is installed respectively. (13) is the secondary cooling pool line, and this On the secondary cooling pool line (13), as shown in Fig. 2, a cart (14) is movably placed via a car (15). The parts are connected in a chain with bottles.On the top of the trolley (14), one frame is removed and a

With the fiKf type transfer device installed in parallel between the next cooling pool line (13), f; # B',! on the upper molding line (2) side. After the primary cooling, the transfer and holding device (19) separates the upper frame into the I pieces to be further cooled, and then transfers the t<r type (1) held in the lower frame (17) to the secondary cooling pool line. (13), and the mold transfer equipment fa-(20) of the lower wall molding line (3) (illll) is held in the lower frame (17) and secondarily cooled. The mold (16) is circulated through the molding line (1).
) The cast product is thin and needs to be demolded quickly, and if the punch-out method is used for demolding, the fRf product may be damaged or bent. In this case, a product transport conveyor (21) is installed in the space between the circulating mold making line (1) and the secondary cooling pool line (13), and the starting end of this product transport conveyor (21) and the two-frame separation device (6) are installed. ) between the circulating mold making line (1) immediately after passing through.

A product lifting device (22) may also be provided.

(Z3) separates the sand attached to the cast product (18) and the cast product (18).1. The vibration conveyor (23) is connected to the conveyor (24) for conveying the sand-separated casting (18). This section explains the operation of the device.

The lower frame (1) holds the lower mold molded by the lower mold molding machine (8).

At the same time, the upper frame, which was sent over the Tateri molding line (1), was further moved over the secondary cooling pool line (13) for one pitch using a truck that moved the upper frame over the Tateri mold making line (1). moved forward. In this way, the trolley (14) with the lower frame (17) set at 4 < 6 is moved by 1 pitch on the secondary cooling pool line (13), and the mold is removed.

After cleaning, the empty lower frame is sent to the lower molding machine (8) again for molding operation.

In addition, if you punch out a thin-walled cast product when removing it from the mold, the cast product may be damaged or bent.
After the primary cooling, the upper frame is separated by the upper separation device (6), and then the cast product is lifted from the lower frame onto the product conveyor (21) by the product lifting device N (22). good.

In addition, in the above embodiment, the circulating mold making line (1

As is clear from the above explanation 1, according to the present invention, it is possible to efficiently use both long and short cooling times for castings, and when a long cooling time is required, After the second cooling, after separating the upper layer, the pouring mold is held only in the lower frame for the second cooling, so the number of upper frames is small, and the installation cost is economical. It has a significant effect on this type of industry.
