Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device suitable for transporting a horizontally split flaskless mold from a molding machine to a predetermined location.

Conventionally, the transportation of horizontally split flaskless molds from the molding machine to the designated location was generally done due to the molding line.
The molds are once extruded from the molding machine onto a belt conveyor and transported to a fixed location by the belt conveyor, and then extruded from the belt conveyor onto a pallet conveyor, placed on the pallet conveyor, and transported to a predetermined location. It is going by.
Therefore, since the molds are transferred at least twice before being transferred from the molding machine to a predetermined pallet conveyor, there have been problems such as the upper and lower molds being displaced from each other and the resulting castings being inconsistent.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a mold conveying device that can move a mold from a molding machine to a pallet conveyor with just one transfer. .

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

1 is a molding machine for intermittently and continuously molding horizontally split frameless molds M one set at a time, and is installed on a foundation. Reference numeral 2 denotes an extrusion cylinder for extruding the mold M on the transfer member 3 of the molding machine 1 onto the trolley 4, and is located on the left side of the molding machine 1 and installed on the foundation. The trolley 4 has an upper surface large enough to accommodate three molds M arranged side by side as shown in FIG. 2. Reference numeral 5 designates a first lifter for raising the cart 4 adjacent to the transfer member 3 to a height where the upper surface level matches that of the transfer member 3. In the first lifter 5, as shown in FIG. Two upward cylinders 6, 6 are installed on the foundation frame 7 located on the left side of the molding machine 1 with a required interval left and right, and two cylinders parallel to each other are installed between the upper ends of the piston rods of the cylinders 6, 6. Tie bars 8, 8 are installed via intervening members 9, 9, and a support member 10 for mounting the trolley 4 is supported on the tie bars 8, 8 so as to be slidable left and right. It is structured so that it can be moved to three positions: right, center, and left by the expansion and contraction of a horizontal cylinder 11 that is pivotally supported on the base frame 7. Reference numeral 12 denotes a second lifter for further raising the cart 4, which has been raised to the same height as the transfer member 3 due to the lifting of the support member 10, to a required height.In the second lifter 12, as shown in FIG. 13 is installed at a position between the cylinders 6, 6 on the base frame 7, and at the upper end of the piston rod of the cylinder 13, there is an elevating table 15 equipped with a rail 14 extending in the front and rear direction on which the wheels 4a, 4a of the truck 4 are placed. The lifting table 15 is prevented from rotating by vertically disposing a guide pin 16 that slidably engages with the base frame 7.
The upper surface level of the rail 14 when the elevating table 15 is lowered is set to a height that allows the cart 4 to move onto the elevating table 15 while the support member 10 is being lowered. Reference numeral 17 denotes a rail frame for laying rails for guiding the trolley 4, and includes a first lifter 5 and a second lifter 12.
It is located on the right side of the building and is installed on the foundation. Then, an empty trolley 4 is placed on the rail 14 of the lowered elevating table 15 from a predetermined place on the rail frame 17.
rails 18 for guiding and lifting table 1
Rails 19 for guiding the trolley 4 on which the mold M is placed to a predetermined location from the rails 14 of the elevating table 15 which has been raised by the lifting of the mold M are respectively extended to the right. Further, the upper surface level of the rail 18 is made to match that of the rail 14 of the elevating table 15 when descending, and the upper surface level of the rail 19 is made to match that of the rail 14 of the elevating table 15 when ascending. Further, a cart loading cylinder 20 is installed above the rail 18 for intermittently pushing the leftmost carts 4 on the rail 18 onto the lifting table 15 one by one.
A locking mechanism 22 having a hanging member 21 for the trolley 4 that is rotatable only in a clockwise direction is connected to the tip of the piston rod 0 so as to be able to reciprocate from side to side. Reference numeral 23 denotes a cart carry-out cylinder for intermittently pushing out the carts 4 on which the molds M are placed one by one from the lifting table 15 onto the rail 19. An engagement mechanism 26 having an engagement member 25 capable of engaging with the left side surface of the elevated truck 4 is connected to the tip thereof so as to be able to reciprocate from side to side. 27
is a stopper provided on the rail 18 for stopping the truck 4, and is configured to open in conjunction with the extension operation of the cylinder 20.

With this structure, first, the lifting table 15 and the support member 10 are lowered and the support member 1 is lowered.
0 is positioned below the lifting table 15, and in this state, the locking mechanism 22 is reciprocated from side to side by the extension operation of the cylinder 20, and the 41 empty carts at the left end on the rail 18 are moved to the lifting table 15. Then, by the extension operation of the cylinders 6, 6 of the first lifter 5, the supporting member 10 is raised to push up the empty trolley 4 from above the rail 14, and the upper surface level of the trolley 4 is moved to the passing member 3. and match it. Next, the mold M formed by the molding machine 1 and existing on the transfer member 3 is pushed to the right by the telescopic operation of the extrusion cylinder 2 and transferred onto the empty truck 4.
The telescopic operation of the cylinder 11 moves the truck 4 forward,
After moving to three positions, center and rear, and transferring the three molds M, M thereon, the carriage 4 is moved to the center position by actuation of the cylinder 11. After the transfer of the mold M to the cart 4 is completed, the elevating table 15 is raised by the extension operation of the cylinder 13 of the second lifter 12, the cart 4 on which the mold M is placed is placed on the elevating table 15, and the support member 10 to make the upper surface level of the rail 14 of the lifting table 15 match that of the rail 19, and then, by reciprocating the engagement mechanism 26 left and right by the expansion and contraction operation of the cylinder 23, the trolley 4 is lifted from the rail 14. Move it onto the rail 19. Thereafter, the trolley 4 on which the mold M is mounted is moved to the right by appropriate means to a predetermined location.

In the above embodiment, the upper surface of the trolley 4 is large enough to accommodate three molds M, but the number is not limited in any way. Further, although the mold M is transported on the trolley 4, it may be carried on a surface plate instead of the trolley 4. In this case, the rails 14, 18 and 19 are provided with collars. It is changed to a roller conveyor equipped with rollers such as rollers.

Since the present invention is constructed as described above, it is possible to raise an empty cart to a transfer member of a molding machine and intermittently reciprocate along the lateral direction of the transfer member using a device with a simple mechanism that does not take up much space for installation. This allows multiple molds to be placed side by side on a trolley,
Moreover, after the mold on the transfer member is transferred onto the trolley, it can be transported to a predetermined location with the trolley without further transfer, so the transfer of the mold from the molding machine is done in one step. It is now possible to transport the mold to the designated location in just one turn.
As a result, the upper and lower molds hardly shift relative to each other, resulting in excellent effects such as a drastic reduction in the occurrence of cracks in the casting.
