Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical split mold making machine in which both a stationary mold and a movable mold are rotated downward by 90° in a vise device. The present invention relates to a vertically split mold making machine equipped with a mechanism suitable for arranging molds (gold).

When a chiller is set in an inverted mold and a mold with a chiller is manufactured, the chiller is conventionally placed in the mold manually or after the mold is released from the mold which has been inverted upwards. Although this is done automatically using a specific insertion mechanism, the risk of manual work and the need to set the chiller after removing the mold increases the working time, thus reducing the productivity of automated mold making machines. This is the current situation.

The present invention has succeeded in eliminating the defects of the conventional method and increasing productivity by providing a mechanism that can safely set the chiller at the same time as other operations. The range is as specified in each section.

The structure and operation mode of the present invention will be described in detail based on one embodiment of the present invention shown in the accompanying drawings.

Fig. 1 is a front view of the device of the present invention, showing the state before the start of operation, and Fig. 2 is a side view of Fig. 1 (arrow ■-■ side);
FIG. 3 is a front view showing a state in which both molds are turned downward by 90 degrees.

In the figure, a stationary mold 7 is attached to the die rate 4 of the vise device that is fully attached to the columns 2 and 2', a movable mold 8 is attached to the other gouly plate 9, and both molds 7 , 8 face each other at their vertical split planes.

A blow bed 18 suspended from a trolley 16 running on a rail (not shown) and a gassing head 1γ are arranged side by side on the upper plate 3, and a crimping head 1γ having a hopper 23 and a blow valve 21 on the upper portion of the upper plate. The cylinders 22 are arranged at a sand replenishment position and a sand blowing position, respectively.

Immediately below the movable mold 8, on the upper surface of the bed 1, an unloader 1, that is, a mold take-out and carry-out device, which can be raised and lowered and has a conveyor belt 34 is provided, and on the side of the bed 1, a chiller arrangement device is provided. , this chiller installation device is chiller frame 2
It has a chiller truck 27 with rollers 28 running horizontally on the chiller truck 27, and has a chiller receiver 31 at the tip of a rod of a cylinder 29 provided on the chiller truck 27, as a mechanism for holding a chiller 32 of a predetermined shape. It is configured so that it moves directly below the stationary mold 7 which has been reversed by 90 degrees.

The movable mold 8 is attached to the movable frame 11 which is locked to the piston rod 13 of the mold clamp cylinder 14 via the die plate 9, and the clamp cylinder 1
4, the tie bar 15 is moved as a guide to the stationary mold 8, and the movable mold 8 is moved downward 9.
It has a movable downward/linder 12 that rotates by 0 degrees.

The die plate 4 to which the stationary side mold T is attached is attached to the rotating shaft 5
The mechanism is such that the stationary mold 7 is turned downward by 90 degrees by the operation of a stationary downward cylinder (shown in FIG. 2).

Reference numeral 25 denotes a mold changing device, which is disposed directly below the mating of both molds.

The present invention has the above configuration, and its operating mode will be explained below.

As mentioned above, FIG. 1 shows the state before the operation starts, and the mold clamp cylinder 14 is operated to move the movable mold 8 to the left in FIG. )do.

In this case, the chiller 3 is already installed in the fixed mold 7 at a predetermined position.
2 is inserted.

At the same time as this clamping process, the blow bed 18 is moved traversely by the actuation of the traversing cylinder 20, the blow plate 19 is placed in the blowing position, and then the crimping cylinder 22 is actuated, and the blow head 18 suspended on the trolley 16 is moved.
are pressed onto the blowing surfaces of the molds 7 and 8, and the air tank 24 is
Molding sand is blown into the mold cavity by the compressed air that has passed through the blow valve 21 and through the blow plate 19 and a nozzle (not shown).

After the blowing and exhausting are completed, the above-mentioned pressure bonding is released, and the blow bed 18 is moved to the sand replenishing position by the operation of the traversing cylinder 20, and at the same time, the gushing head 17, which is attached to the trolley 16 in parallel with the blow head 18, is moved to the sand replenishing position. The gas blowing position is moved to the gas blowing position, the press cylinder 22 is operated to press the mold, and gas is gassed from a gas supply source (not shown) to form the mold.

After the gashing is completed, the pressure on the gashing head 17 is released.

Next, while the mold 35 is held in the movable mold 8, the clamp cylinder 14 is operated to cause the movable mold 8 to
Move to the right to open the mold.

At the same time, the stationary mold 7 is rotated downward 9 in the vice device by the operation of the fixed downward cylinder 6 around the rotating shaft 5.
Flip 0°.

The chiller cart 27 is moved to the right by a drive mechanism (not shown), stops directly below the stationary mold 7 that has been turned downward by 90 degrees, and operates the cylinder 29 to move the chiller 3
2 is placed, the frame 30 is raised, and the chiller 32 is placed in a predetermined position of the mold 7 (the position where the porcelain etc. is buried within the mold), and the chiller 32 is brought into close contact with the mold 7. The truck 27 returns to the standby position.

The opened movable mold 8 retains the mold 35 and moves backward, at the same time actuating the cylinder 12 attached to the movable frame 11, together with the die plate 9 which is fully connected to the hinge part at the tip of the piston rod 12'. , its rotation axis 1
Flip downward 90 degrees with 0 as the center.

The unloader 33 having the belt conveyor 34 rises and approaches the mold 35 held by the movable mold 8 which has been reversed downward by 90 degrees.

Next, the mold 35 is extruded and released by an extrusion device of a known mechanism provided on the back side of the die plate 9, and the mold 35 is transferred to the conveyor 34.
The unloader 33 descends.

As described above, after the mold is released and the chiller 32 is set, the stationary mold 7 and the movable mold 8 are each rotated 90° and then proceed to the next molding operation and operate continuously.

Since the device of the present invention has the configuration as described above,
This method has the following functions and effects over the conventional method: (1) The reversing operation of both molds is performed at the same time, and chiller setting, mold removal, and mold release can be performed within the same time. Therefore, the operating time is shortened and productivity is improved, and the setting of the chiller is automated and there is no danger.

In the conventional method, the mold opposite to the side from which the mold is taken out does not operate during the taking-out operation, but in the present invention, the chiller is set in one of the molds during the taking-out operation.

(2) Since both molds are turned over in the same direction (downward), cleaning and injection of mold release agent can be performed extremely effectively and quickly.

(3) By changing the layout of the mold removal or chiller installation device or the mold shape of the chiller setting reservoir, the functions of the fixed side and the movable side can be interchanged.
