And a second platen carriage feeding device disposed at the other end of the cooling line and configured to feed the platen carriage placed on the second traverser to the cooling line.
The first traverser and the second traverser are respectively
A movable carriage on which the platen carriage is placed and which moves between the pouring line and the cooling line;
The carriage stop means for contacting with the plate carrier placed as described above, and the plate carriage fixing means for contacting with the plate carriage from the opposite side to the carriage stop means, the wheel stopper means and the plate carriage Fixing means holds the fixed platen carriage placed above and fixes it on the movable carriage.

According to such a configuration, in the pouring line, the fixed carriage is fed to the movable carriage of the second traverser by the fixed carriage feeding means. Then, the platen carriage is held between the carriage stopping means and the platen carriage fixing means, and is stopped and fixed on the movable carriage of the second traverser. Further, the cooling line also has the same configuration as the pouring line. That is, in the cooling line, the platen carriage is fed to the movable carriage of the first traverser by the second platen carriage feeding means, and is clamped by the carriage stopping means and the platen carriage fixing means on the movable carriage of the first traverser. Stop and be fixed.

According to a preferred aspect of the present invention, in the cast-out frame for an extrusion frame mold, the platen carriage mounts a wheel and an axle, and the carriage stopping means is in contact with the wheel of the platen carriage, the platen The carriage fixing means abuts on the axle of the platen carriage. According to such a configuration, the carriage stopping means is in contact with the wheel, and the platen carriage fixing means is in contact with the axle, and the platen carriage is clamped and fixed by the platen carriage fixing means and the carriage stopper. .

The platen carriage fixing means and the carriage stopping means do not require the cushion cylinder provided in the conventional extrusion frame casting line, and power such as oil pressure is also unnecessary. Therefore, it leads to the reduction of the installation cost of the casting line for the frame and the reduction of the running cost. Furthermore, when the movable carriage carrying the platen carriage moves between the pouring line and the cooling line, the platen carriage is fixed by being held on the movable carriage by the carriage stopping means and the platen carriage fixing means. Ru. Thus, the platen carriage can be moved safely.

According to another preferred aspect of the present invention, in the cast-out frame for an extrusion frame mold, the fixed plate carriage fixing means has a contact member abutting on the axle and an elastic member displaceably supporting the contact member. Even if it abuts on the axle, the contact member is displaced and the platen carriage is movable, and when the wheel abuts on the carriage stopping means, the contact member is from the opposite side to the carriage stopping means Abuts against the axle to fix the platen carriage on the movable carriage. Thus, the platen carriage can be fixed on the movable carriage without power such as hydraulic pressure.

According to another preferred aspect of the present invention, the weight arm includes a weight raising and lowering claw engaged with the weight when lifting the weight,
The weight lifting and lowering pawl is detachably attached to the weight weight arm.
According to this configuration, partial replacement is possible when the weight lifting pawl is partially worn.

According to another preferred aspect of the present invention, the weight lifting pawl has an inclined surface for correcting the position of the weight when lifting the weight.

When transferring the weight of the cooling line to the pouring line with the weight transfer device, the installation position of the weight may be shifted every cycle due to a slight misalignment at the time of installation. And since this shift is accumulated, a weight transfer apparatus can not lift a weight, and the malfunction of dropping a weight may occur. Therefore, the conventional weight transfer apparatus requires the centering of the weight installation position having a difficult process. According to this configuration, when the weight is lifted by the plurality of weight arms, the “shift” of the weight can be corrected by the inclined surface of the weight lifting and lowering claw. As a result, since "displacement" of the weight is not accumulated, it is possible to prevent the weight arm from dropping the weight. And the centering of the weight installation position conventionally required can be made unnecessary.

According to another preferred aspect of the present invention, the weight raising and lowering claw is a first engagement member detachably attached to the weight arm, and a second engagement detachably attached to the first engagement member. Having a joint member. According to such a configuration, for example, when the inclined surface on which the weight slides is partially worn to a large extent in order to correct the "displacement" of the weight, for example, the inclined surface of the first engagement member is largely worn If this is done, only the first engagement member and only the second engagement member may be replaced if the inclined surface of the second engagement member is significantly worn, and maintenance costs can be reduced.

According to another preferred aspect of the present invention, the jacket transfer device further includes a plurality of rod members which extend in the height direction of the mold and can move vertically.
The lower end of the rod member is disposed to be able to abut on the jacket.
According to this configuration, when the jacket of the cooling line is transferred to the pouring line, the jacket can be pressed from above by the rod member while lifting the jacket from below by the jacket arm. As a result, when transferring the jacket, the transfer can be performed while holding the jacket firmly.

According to another preferred aspect of the invention:
The length of the rod member is adjusted such that the lower end is at a height higher than the upper end of the jacket when moved to the lowermost point.
According to this configuration, when the jacket is put down on the mold of the pouring line, the rod member is separated from the jacket before the jacket is put on the mold even if the position of the jacket with respect to the mold is shifted. Excessive force does not work. Therefore, the jacket can be covered on the mold without causing mold defects such as mold misalignment.

According to another preferred aspect of the invention:
In the casting line for the frame mold,
The weight arm opens and closes in a direction parallel to the advancing direction of the pouring line and the cooling line, and the jacket arm and the weight arm are offset in a direction perpendicular to the opening and closing direction of the weight arm .

There are matters to be considered in order to move the jacket transfer device and the weight transfer device, which are disposed in a completely lowered state in the pouring line, to above the cooling line in a completely lowered state. . That is to prevent the jacket arm and the weight arm from colliding with those (the mold, the jacket and the weight) placed on the platen carriage in the pouring line during lateral movement. Therefore, the open / close direction of the weight arm is made parallel to the advancing direction of the pouring line and the cooling line. It is placed on the platen carriage in the jacket arm and the weight arm and the pouring line by passing the mold between the pouring line and the cooling line while moving the weight arm sideways while passing the mold arm. It becomes possible to prevent collision with (the mold, the jacket and the weight). The jacket arm is configured to lift the jacket without opening and closing, and is configured not to collide with the one (mold, jacket and weight) placed on the platen carriage without opening and closing. It is possible.

On the other hand, since the opening and closing direction of the weight arm is parallel to the advancing direction of the pouring line and the cooling line, when the weight arm is opened, the jacket arm and the weight arm may collide. Therefore, the positions of the jacket arm and the weight arm are shifted in the direction perpendicular to the opening / closing direction of the weight arm. This makes it possible to prevent them from colliding even when the weight arm is open.

According to another preferred aspect of the invention:
In the casting line for the frame mold,
A plate member for mounting the mold in the platen carriage is formed of a steel plate. Conventionally, the plate member of a plate carrier generally used is a casting. According to this configuration, since the steel plate is used, the manufacturing cost of the platen carriage can be suppressed.

The top plate portion of the platen carriage 16 in the conventional die casting mold casting line 1 is formed of a casting. However, castings are expensive to manufacture as compared to steel plates, resulting in heavy weight. The plate carrier 16 whose top plate portion is made of steel plate can solve the above-mentioned problems.

Next, an example of the operation method of the casting frame 1 for the formwork mold of the present embodiment will be described with reference to the drawings.

(Step 1: Pouring line feed process)
After the mold M molded by the frame forming machine 10 is placed on the platen carriage 16 of the pouring line 2 from the carry-in position 11, the first fixed board carriage feeding means 13 operates, and the pouring line 2 The upper platen carriage 16 is pitch fed.

Stop on the movable carriage 12.

A specific method for stopping the platen carriage 16 by the platen carriage fixing means 15 and the carriage stopping means 20 will be described with reference to the drawings. FIG. 4 shows the positional relationship between the platen carriage fixing means 15 and the platen carriage 16. FIG. 4 describes a part of the hidden line with a dotted line. In addition, a phantom line of the wheel 19 and the axle 19a immediately after the axle 19a comes into contact with the fixed carriage fixing means 15 is indicated by a two-dot chain line.
During pitch feeding of the pouring line 2, as shown by a virtual line, the axle 19a of the platen carriage 16 and the contact member 15b of the platen carriage fixing means 15 are in contact with each other. Then, the platen carriage 16 tries to move further forward. Here, the platen carriage fixing means 15 is connected to the support structure via the elastic member 15a. The elastic member 15a is formed of, for example, a knight-hard rubber spring, and has elasticity. Thus, since the contact member 15b is pushed by the axle 19a and displaced, the platen carriage 16 continues to advance toward the carriage stopper 20. Then, when the wheel 19 comes in contact with the carriage stopping means 20, the platen carriage fixing means 15 returns to the original state (the state shown in FIG. 4) according to the elasticity of the elastic member 15a. When the platen carriage fixing means 15 is returned to the original state, the platen carriage 16 is held between the contact member 15b and the carriage stopper 20 as shown in FIG. Ru. Specifically, the contact member 15b and the axle 19a are in contact with each other, and the carriage stopping means 20 and the wheel 19 are in contact with each other so that the fixed carriage 16 is stopped and fixed on the movable carriage 12.

(Step 2: Second Traverser Transfer Step)
The movable carriage 12 of the second traverser 5 on which the platen carriage 16 is placed is moved along the cooling line 3. When the platen carriage 16 is arranged on the movable carriage 12, the platen carriage 16 is fixed on the movable carriage 12 by the contact member 15 b and the carriage stopper 20. Therefore, the platen carriage 16 can be stably positioned on the movable carriage 12.

(Step 3: Cooling line feeding step)
After the movable carriage 12 of the second traverser 5 moves along the cooling line 3, the second platen carriage feeding means 14 is activated, and the platen carriage 16 on the cooling line 3 is pitch-fed. At this time, the platen carriage 16 moving from the cooling line 3 to the movable carriage 12 of the first traverser 4 is moved by the platen carriage fixing means 15 and carriage stopping means 20 disposed on the movable carriage 12 of the first traverser 4. Stop on the movable carriage 12. The configuration of the first traverser 4 and the configuration of the second traverser 5 are the same, and the specific method of stopping the platform carriage 16 by the platform carriage fixing means 15 and the carriage stopping means 20 is the same as the contents of step 1 described above. It is.

In the present embodiment, the delivery speed of the platen carriage 16 by the first platen carriage feeding means 13 and the second platen carriage feeding means 14 is a low speed (for example, about 1/5 of the conventional speed). Therefore, the platen carriage 16 can be safely stopped on the movable carriage 12 by the platen carriage fixing means 15 and the carriage stopping means 20 even if there is no deceleration means such as a cushion cylinder.

(Step 4: First Traverser Transfer Step)
The movable carriage 12 of the first traverser 4 on which the platen carriage 16 is placed is moved along the pouring line 2. When the platen carriage 16 is placed on the movable carriage 12, the wheel 19 is in contact with the carriage stopper 20 and the axle 19 a is in contact with the platen carriage fixing unit 15. Therefore, the platen carriage 16 can be stably positioned on the movable carriage 12.

As described above, by the steps 1 to 4, the group of platen carriages 16 in the present embodiment can circulate on the draft frame casting line 1. Next, the process of transferring the weight W and the jacket J present on the cooling line 3 onto the pouring line 2 will be described.

(Step 5: jacket transfer process)
The jacket transfer device 6 is raised with the jacket arm 6A in the jacket transfer device 6 in a closed state and in a state of being caught by the jacket collar JF covering the mold M on the cooling line 3. In addition, when the jacket transfer device 6 is elevated, the lower ends of the four rod members 23 hit the upper end of the jacket collar JF, and the rod 23 pushes up the jacket collar JF while rising with the jacket collar JF. Do. Then, after raising the jacket transfer device 6 to the rising end, it is moved laterally to above the mold M of the pouring line 2. While the jacket transfer device 6 is moving up, the jacket collar JF pushes the jacket lifting claw 6B by the weight of the rod 23 and the weight. That is, when the jacket J is moved from the cooling line 3 to the pouring line 2, the jacket J is fixed to the jacket transfer device 6 by the jacket ridge JF being sandwiched between the rod member 23 and the jacket lifting claw 6B. Be done.

Next, the jacket transfer device 6 is lowered to the lowering end, and the jacket J is put on the mold M on the pouring line 2. At this time, the rod member 23 separates from the jacket collar JF immediately before the jacket J covers the mold M (immediately before the inner surface of the jacket J contacts the mold M). That is, the jacket lifting claws 6B are easily displaced from the jacket collar JF and easily removed. Thus, the transfer of the jacket J is possible without opening the jacket arm 6A, but the jacket arm 6A may be opened and closed at the same time as the weight arm 7A.

(Step 6: weight transfer process)
When the weight arm 7A in the weight transfer device 7 changes from the open state to the closed state, the weight arm portion WF of the weight W placed on the mold M on the cooling line 3 is caught. Then, the weight transfer device 7 lifts the weight W by lifting. After the weight transfer device 7 ascends to the rising end, the weight W is moved to the upper side of the mold M of the cooling line 3 by moving laterally. Next, the weight W is placed on the mold M on the pouring line 2 by lowering to the falling end of the weight transfer device 7. Thereafter, the weight arm 7A is opened to release the hook with the weight rod portion WF.

As shown in FIGS. 6 and 7, the weight transfer device 7 has four weight arms 7A, and the four weight arms 7A each have weight lifting and lowering claws 7B. The four weight arms 7A lift the weight W by hooking the four corners of the weight with the weight lifting claws 7B. Further, when the weight lifting and lowering claw 7B hooks the four corners of the weight, the weight W is lifted after the position of the weight W is corrected.

Here, a method of correcting the weight W by the weight lifting and lowering claw 7B will be described with reference to FIG. FIG. 9 is an enlarged view showing a weight lifting and lowering claw 7B (formed by the first engagement member 21 and the second engagement member 22) in one weight arm 7A. Here, it is assumed that the position of the weight W is closer to the weight raising and lowering claw 7B than the reference position. In this case, when the weight transfer device 7 lifts the weight W on the cooling line 2, the weight arm 7A while the ridges R1 and R2 of the weight rod portion WF in the weight W hit the inclined surfaces K1 and K2. Will rise. Therefore, when the weight arm 7A ascends, the position of the weight collar portion WF is corrected to return to the reference position. After being corrected, the weight cage WF is placed on the plane F. The present embodiment has four weight arms 7A, and has the same effect. Therefore, when the weight arm 7A is lifted, it is possible to correct the position of the weight W which is shifted in any direction.

As described above, the jacket J and the weight W present in the mold M on the cooling line 3 are transferred to the mold M on the pouring line 2 by the jacket transfer device 6 and the weight transfer device 7 in steps 5 and 6. It is replaced. In the present embodiment, step 3 is performed while steps 5 and 6 are performed. That is, while step 5 and step 6 are performed, the platen carriage 16 on the cooling line 3 is pitch-fed.

(Step 7: Transfer device return step)
After the jacket transfer device 6 places the jacket J on the mold M on the pouring line 2, the jacket arm 6A is released from the jacket collar JF. Then, in order to transfer the next jacket J, the jacket transfer device 6 moves only in the horizontal direction without rising (transversely moves as it is), and moves onto the cooling line 3. Further, after the weight transfer device 7 places the weight W on the casting mold M on the pouring line 2, the weight arm 7A is opened to release the weight W. Then, in order to transfer the next weight W, the weight transfer device 7 moves only in the horizontal direction without rising (moves sideways as it is), and moves onto the cooling line 3. This is because the jacket arm 6A and the weight arm 7A are offset from each other as viewed from the side direction of the casting frame 1 for the frame, and the jacket arm 6A does not interfere with the weight arm 7A even if it is opened. It becomes possible. Conventionally, in order to cause interference, the opening direction is generally orthogonal, and in this case, when moving in the horizontal direction, the jacket arm and the weight arm are not raised and either of the molds M is used. It was a structure that would collide. In addition, since the mold M on the pouring line 2 and the mold M on the cooling line 3 are at the same position in the transport direction, the jacket arm 6A and the weight arm 7A in the open state are moved horizontally. Even if it moves between the mold M, the jacket J or the weight W, it can move without colliding.

The jacket transfer device 6 and the weight transfer device 7 of the present embodiment are integrated as a jacket weight transfer facility 8 by the connection frame 9. Further, the movement of the jacket transfer device 6 and the weight transfer device 7 in the raising and lowering direction is performed by the raising and lowering cylinder 17, and the movement in the lateral direction is performed by the lateral moving cylinder 18. That is, the jacket transfer step (step 5) and the weight transfer step (step 6) are performed simultaneously. Further, the movement of the jacket weight transfer facility 8 in the raising and lowering direction and the movement in the lateral direction are each performed by one cylinder.

Next, an operation and an effect of the casting frame 1 for a formwork mold of the present embodiment will be described.
The jacket transfer device 6 and the weight transfer device 7 are integrated by a connecting frame 9. The movement of the jacket transfer device 6 and the weight transfer device 7 in the raising and lowering direction is performed by the raising and lowering cylinder 17, and the lateral movement is performed by the lateral moving cylinder 18. That is, the movement in the up and down direction and the movement in the lateral direction of the two devices are performed by one cylinder each. Therefore, as compared with the case where each of the jacket transfer device 6 and the weight transfer device 7 is provided with the elevating cylinder 17 and the lateral movement cylinder 18, the weight of the facility can be reduced, and the facility cost can be reduced.

In addition, as the number of cylinders decreases, the number of various sensors that measure the speed of the cylinders can also be reduced. By reducing the number of various sensors, it is possible to reduce the wiring of the control board, and it is also possible to make the control board itself smaller.

The platen carriage 16 pitch-fed by the pouring line 2 and the cooling line 3 is stopped by the platen carriage fixing means 15 and the carriage stopping means 20. In the prior art casting frame for scissor molds, the method for stopping the pitched platen carriage has generally been performed using a cushion cylinder. However, cushion cylinders generally require power such as hydraulic pressure. On the other hand, the platen carriage fixing means 15 and the carriage stopping means 20 do not require power. Moreover, compared with a cushion cylinder, installation cost can be held down cheaply. Therefore, the casting frame 1 for a formwork mold of the present embodiment contributes to the reduction of the running cost and the reduction of the equipment cost by not requiring the power.

The jacket transfer device 6 covers the mold M on the pouring line 2 and then moves only horizontally in the vertical direction without moving up and moves onto the cooling line 3. Further, after the weight transfer device 7 places the weight W on the casting mold M on the pouring line 2, the weight transfer device 7 moves only in the horizontal direction without moving up and moves onto the cooling line 3.

Here, the movements of the prior art jacket transfer device and weight transfer device are compared with the movements of the jacket transfer device 6 and weight transfer device 7 of the present invention.

The jacket transfer device in the prior art grips the jacket covered with the mold on the cooling line and then performs one cycle in the order described below.
Step 1: Raise the jacket on the cooling line.
Step 2: Move the jacket laterally from above the cooling line onto the pouring line.
Step 3: Lower the jacket on the pouring line.
Step 4: Cover the mold on the pouring line with a jacket.
Step 5: Rise on the pouring line.
Step 6: Move laterally from above the pouring line onto the cooling line.
Step 7: Lower on the cooling line.
Step 8: Grab a jacket covered on the mold on the cooling line.
Moreover, after the weight transfer device in the prior art grips the weight placed on the mold on the cooling line, it performs one cycle in the order described below.
Step 1: Raise the weight on the cooling line.
Step 2: The weight is moved laterally from the cooling line to the pouring line.
Step 3: Lower the weight on the pouring line.
Step 4: Place a weight on the mold on the pouring line.
Step 5: Rise on the pouring line.
Step 6: Move laterally from above the pouring line onto the cooling line.
Step 7: Lower on the cooling line.
Step 8: Grab the jacket placed on the mold on the cooling line.

On the other hand, the jacket transfer device 6 in the present invention holds the jacket J which has been placed on the mold M on the cooling line, and then performs one cycle in the order described below.
Step 1: Raise the jacket J on the cooling line 3.
Step 2: The jacket J is moved laterally from the cooling line 3 to the pouring line 2.
Step 3: Lower the jacket J on the pouring line 2
Step 4: The mold J on the pouring line 2 is covered with a jacket J.
Step 5: Move from the pouring line 2 side to the cooling line 3 sideways.
Step 6: Grab the jacket J placed on the mold M on the cooling line 2.
Further, after the weight transfer device 7 in the present invention grips the weight W placed on the mold M on the cooling line 3, it performs one cycle in the order described below.
Step 1: Raise the weight W on the cooling line 3.
Step 2: The weight W is moved laterally from the cooling line 3 to the pouring line 2.
Step 3: The weight W is lowered on the pouring line 2.
Step 4: The weight W is placed on the mold M on the pouring line 2.
Step 5: Move from the pouring line 2 side to the cooling line 3 sideways.
Step 6: Grab the jacket J placed on the mold M on the cooling line 3.

The jacket transfer device 6 in the present invention can remove steps 5 and 7 among the steps 1 to 8 of the jacket transfer device in the prior art. Similarly, the weight transfer device 7 according to the present invention can remove steps 5 and 7 among the steps 1 to 8 of the jacket transfer device in the prior art. That is, the time required for one process is shorter than in the conventional case.

The cylinder used in the prior art jacket weight transfer facility has generally been able to change the expansion and contraction speed in multiple stages by using a speed controller and a switching valve. Thereby, compared with the case where the expansion-contraction speed of a cylinder is only 1 speed, the time concerning movement of the jacket transfer apparatus and weight transfer apparatus by expansion-contraction of a cylinder can be shortened.

However, using the speed controller and the switching valve increases the equipment cost. In addition, the speed controller and switching valve also require piping and wiring, which also increases the equipment cost. Furthermore, it is necessary to design the frame of the jacket weight transfer facility in consideration of the load applied to the jacket weight transfer facility when changing the expansion and contraction speed of the cylinder.

The elevating cylinder 17 and the lateral movement cylinder 18 in the present invention are each set to an expansion / contraction speed of only one speed (a low speed not to load the jacket weight transfer facility 8). Therefore, the configuration of the multi-stage transmission circuit such as the 2-speed circuit is unnecessary, and the necessary piping, wiring, and the like can be reduced. For example, in the case of a 2-speed circuit, two switching valves are required for each cylinder, but in the case of a 1-speed circuit, only one switching valve is required for each cylinder. Thereby, the installation cost of the jacket weight transfer installation 8 can be held down cheaply. Here, "first gear" indicates that the expansion and contraction speed set in the cylinder is only one.

In addition, there is no load on the jacket weight transfer facility 8 due to the change of the extension speed of the lifting cylinder 17 and the lateral moving cylinder 18 due to the extension speed of the lifting cylinder 17 and the lateral moving cylinder 18 being the first speed. . Therefore, the strength can be set lower than the frame of the conventional jacket weight transfer facility. Accordingly, the structure of the frame can be simplified, so the weight of the jacket weight transfer facility 8 can be reduced. Therefore, the manufacturing cost of the jacket weight transfer facility 8 can be reduced.

In the present embodiment, the increase in the process time associated with setting the expansion / contraction speed of the elevating cylinder 17 and the lateral movement cylinder 18 to the first speed reduces the number of processes of the jacket transfer device 6 and the weight transfer device 7 described above. Offset by reductions in process time associated with That is, in the extrusion frame casting line, the timing of pitch feeding is adjusted to the time for pouring the molten metal into the mold, and there is no substantial advantage in making the processing time fast. It is more meaningful to reduce the cost of equipment by making good use of the time taken to reduce one process in another process.

The jacket transfer device 6 and the weight transfer device 7 are integrated by the connecting frame 9 and are close to each other. On the other hand, the open / close direction of the weight arm 7A is horizontal to the pouring line 2 and the cooling line 3. Therefore, in some cases, when the weight arm 7A is opened, the jacket arm 6A and the weight arm 7A may be in contact with each other. Therefore, as shown in FIG. 7, the jacket arm 6A provided in the jacket transfer device 6 and the weight arm 7A provided in the weight transfer device 7 are shifted in the direction perpendicular to their opening / closing direction. Be placed. As a result, even when the weight arm 7A is opened, the jacket arm 6A and the weight arm 7A do not have to be in contact with each other.

When the jacket J covers the mold M on the pouring line 2, if the inner surface of the jacket J contacts the mold M while the rod member 23 is in contact with the jacket J, the mold M may be misaligned. This is because the jacket J remains fixed to the jacket transfer device 6, and the jacket J pushes the mold M with an excessive force.
According to the present embodiment, the rod member 23 in the jacket transfer device 6 immediately before the jacket J covers the mold M on the pouring line 2 during the jacket transfer process (the inner surface of the jacket J contacts the mold M) The length is adjusted so as to separate from the jacket heel portion JF immediately before In other words, when the rod member 23 moves to the lowest point, the length is adjusted so that the lower end is at a height higher than the upper end of the jacket J. Therefore, even if the position of the jacket J with respect to the mold M is shifted, for example, the mold J can be covered along the outer shape of the mold M without the jacket J pushing the mold M with an excessive force on the inner surface.

ADVANTAGE OF THE INVENTION According to the cast-out line for the formwork mold of this invention, weight reduction of the whole installation which comprises the casting line for formwork molds can be achieved. Further, by reducing the weight of the entire equipment, the size of the actuator can be reduced, and the running cost of the actuator can be reduced. And, it is also possible to reduce running costs by reducing the number of processes. Furthermore, the reduction in weight and running cost of the casting frame for the extrusion frame mold can be achieved by the reduction of the number of actuators.
