Description

[Detailed Description of the Invention] The present invention relates to a pattern shuttle device with a mold extrusion device.

Generally, pattern shuttle and mold extrusion were performed independently using separate drive devices, but this required two drive devices, lengthened the time cycle, and reduced productivity. There were flaws.

The present invention aims to solve these problems.

The configuration of the present invention will be explained below based on examples. 1 is a foundation frame, and on the upper surface of one side of this foundation frame 1 is a bed 3 with pillars 2 erected at the four corners.
A squeeze cylinder 4 is attached to the center of the bed 3 facing upward, and an elevating table 5 is fixedly connected to the tip of the piston rod.

Above the lift table 5, a pair of guide rails 6 are provided with a width interval that allows the lift table 5 to pass through, passing through the inside of the support column 2 and extending from side to side. 2 via the support member 7, and the other end is connected to the foundation frame 1.
The other end is supported by the upper end of a support leg 8 which is erected on the upper surface. Reference numeral 9 denotes a frame body, on which a pattern plate 11 with a model 10 is mounted at the center of the upper surface, and a window frame-shaped master plate 12 with a space in the center on the outer periphery.
A pair of wheels 14 are mounted on the lower surface near the left and right ends of the master plate 12 (with respect to the drawing in FIG. 1), and are rotatably supported via a support member 13. They are attached in pairs and are engaged with the guide rail 6 so as to be movable.

Further, a pair of shaft support brackets 15 are provided near the center of the lower surface near the left end of the master plate 12 at a predetermined distance in the front-rear direction.
The shaft support bracket 15 has a reinforcing frame 16 on the back side of the plate member 17, and a seat 1 on the lower front side.
The reinforcing frame 16 is rotatably supported by a mold extrusion plate 18 to which the reinforcing frame 16 is attached, and a stepped portion 20 is formed at the upper end of the reinforcing frame 16. A hook-shaped stopper member 21 fixed to the lower surface of the master plate 12 adjacent to the shaft support bracket 15 is adapted to abut and engage with the counterclockwise rotation of the mold extrusion plate 18. There is. Further, the base end of a bent guide arm 22 is rotatably supported by one of the pins 19, and the guide arm 22 is brought into contact with the back surface of the mold extrusion plate 18 via a contact member 23. The tip is slidably engaged with a cam rail 24 to be described later, and when the frame 9 returns, the cam rail 2
4 and is engaged and guided to fall upward into a substantially horizontal state. Then, the cam rail 24
is the guide rail 6 parallel to the guide rail 6.
is supported via a support member 25 on the lower surface of the
Both ends are expanded. 26 is a supporting member 2 with one end attached to the support column 2 and the other end attached to the supporting leg 8.
The guide bar 26 is supported through guide bars 7 and 28, and is provided in parallel with the guide rail 6, and a guide holder 29 is slidably fitted into the guide bar 26. The tip of a link 31 is rotatably connected to the arm rod 30 projecting downward from the guide holder 29 with a pin 32, and the base end of the link 31 is attached to the upper surface of the base frame 1. A swing link 35 whose base end is rotatably supported by a pin 34 is rotatably connected to a pin 36 at the tip thereof, and a support arm 37 extends upward from the guide holder 29. A positioning pin 38 is erected on the upper surface of the master plate 12 and is removably inserted into the positioning hole of the master plate 12.

The tip of a piston rod 40a of a traveling cylinder 40, which is slidably supported on the upper surface of the base frame 1 via a cylinder bracket 39, is rotatably attached to a pin 41 at an intermediate portion of the swing link 35.
When the traveling cylinder 40 is connected, the guide holder 29 is slid along the guide bar 26 via the swing link 35 and the link 31, and the frame 9 and the pattern plate 11 are moved.
The master plate 12 and the mold extrusion plate 18 are moved while the wheels 14 are engaged with the guide rails 6. Reference numeral 42 denotes a roller retainer provided to prevent the wheel 14 from flying up, and is provided at an upper position of the guide rail 6 in parallel with the guide rail 6, and has a notch 42 in the middle part.
a is formed, and the notch 42a is provided so that the wheels 14 do not interfere when the shapes are matched by the lifting operation of the lifting table 5. Reference numeral 43 denotes a notch provided in the horizontal portion of the guide rail 6, and is provided so as not to interfere with the guide arm 22 during mold matching.

Incidentally, reference numeral 44 denotes upper and lower molds which are removed from a pair of superimposed frames and placed on the upper surface of the lifting table 5.

Next, the operation of the device configured as described above will be explained. In the illustrated state, when the shuttle cylinder 40 is extended, the guide holder 29 is slid leftward along the guide rod 26 via the swing link 35, the link 31, and the arm rod 30, and the frame 9 , pattern plate 11
The master plate 12 is moved to the left together with the mold extrusion plate 18 while engaging the wheels 14 with the guide rail 6, and is positioned directly above the lifting table 5. On the other hand, while traveling, the guide arm 22 is engaged with and guided by the cam rail 24 and moved forward to the left while sliding within the cam rail 24, and the upper and lower molds 44 placed on the upper surface of the lifting table 5 are It is extruded onto a conveyor (not shown) by a extrusion plate 18.

Note that this extrusion operation employs a link mechanism, so that it is possible to extrude the upper and lower molds 44 without damaging them.

Next, the elevating table 5 is raised by the extension operation of the squeeze cylinder 4, and the guide rail 6 is raised.
The frame body 9, pattern plate 11, and master plate 12 placed above are lifted up and down as one body by the lifting table 5, and are superimposed on the frame body (not shown) above, and these superposed frame bodies 9, molding sand is supplied and squeezed. After the squeeze is completed, the lift table 5 is lowered by the reverse operation of the squeeze cylinder 4, and on the way, the frame 9,
Pattern plate 11 and master plate 12
is left on the guide rail 6, and the lower mold 44a from which the frame has been removed is placed on the upper surface of the lifting table 5. Subsequently, by the reverse operation of the shuttle cylinder 40, the frame body 9, pattern plate 11, and master plate 12 are moved backward to the right together with the guide holder 29 while engaging the wheels 14 with the guide rail 6. The guide arm 22 is engaged with and guided by the cam rail 24, and the first
As shown by the two-dot chain line in the figure, the pin 19 is used as a fulcrum and the pin 19 is turned upward into a substantially horizontal state, and then moved to the right without interfering with the lower mold 44a placed on the upper surface of the lifting table 5. state.
Thereafter, the upper mold 44b is fitted onto the lower mold 44a, and the above operation is repeated thereafter.

In the above embodiment, the pattern plate 11 with the model 10 and the master plate 12 are separated, but they may be integrally formed.

As is clear from the above explanation, according to the present invention, pattern shuttle and mold extrusion can be performed at the same time using a single drive device, which simplifies the device and shortens the time cycle. This has the effect of improving performance, and the effect of contributing to this type of industry is significant.
