Description

[Detailed explanation of the idea] This invention relates to frame alignment encounters.

Conventionally, when aligning the upper frame with the lower frame, the upper frame 40 is guided by guide pins 41 extending downward through the flange portion 40a and aligned with the lower frame 42, as shown in FIG. It's becoming like that. Therefore, a hole 43 through which the guide pin 41 passes is required in the upper flange portion 40a of the upper frame 40, and hot water spilled from this hole 43 during pouring falls into the frame bush 44, which prevents the frame from separating after pouring. There was a problem that the pins of the pattern plate could not be fitted into the frame bushings 44 during mold matching during molding.

The present invention aims to solve these problems.

The configuration of the present invention will be explained below based on examples. Reference numeral 1 denotes a gate-shaped frame in which four support frames 2 are erected at substantially equal intervals from each other, and their upper ends are connected by an upper frame 3. A lower frame 4 is located at the bottom of this gate-shaped frame 1. Two guide pin cylinders 5 for frame alignment are mounted upwardly on the upper surface of the lower frame 4 at a constant interval. At the tips of the piston rods 5a of the guide pin cylinder 5, guide pins 6, each of which is elongated and has an inverted conical tip, are oriented upward and fixed and connected. The upper frame bushings 10 and lower frame bushings 11 of the upper and lower frames 8 and 9 are movably placed on a conveyor 7 passing through the upper and lower frames 8 and 9, respectively. The upper frame 8 is
As shown in FIG. 3, an upper flange portion 8a is provided on the outer periphery
and the lower flange part 8b are provided around the lower flange part 8.
Fitting holes 8c of the upper frame bushing 10 are provided at both sides of the center b, and each fitting hole has a
The upper frame bushing 10 is fitted through the upper shaft 10a, and the upper frame bushing 10 is attached to the lower surface of the lower flange portion 8b via the flange portion 10b. Further, the lower frame 9 has an upper flange portion 9a and a lower flange portion 9b on the outer periphery, and fitting holes 9c for the lower frame bushings 11 are bored at positions on both sides of the center of the upper flange portion 9a. A through hole 9d through which the guide pin 6 passes is provided in the flange portion 9b on the same line as the fitting hole 9c, and a lower frame bush 11 is provided in each fitting hole 9c.
The shaft portion 11a of the lower frame bushing 11 is fitted with the flange portion 1 on the upper surface of the upper flange portion 9a.
It is attached via 1b.

The upper frame 8 and the lower frame 9 are connected by guide pins 6 that are inserted from below the lower frame 9 into the pin holes of the lower frame bushing 11 and the upper frame bushing 10 through the through holes 9d of the lower flange portion 9b. While being positioned, the upper frame bushing 10 is fitted into the recess 11c of the lower frame bushing 11 via its lower shaft 10a, and the frames are aligned.

Therefore, the spilled hot water during pouring is blocked by the upper flange portion 8a of the upper frame 8 and flows into the upper frame bush 1.
0 and the lower frame bush 11.

Reference numeral 12 denotes a frame alignment cylinder attached downward to the upper frame 3 above the guide pin 6, and a lifting table 13 is attached to the lower end of the piston rod 12a.
Further, the upper end of a link 14 is rotatably connected to a pin 16 via a support member 15 attached at a predetermined interval to the lower surface of this lifting table 13. A flexible table 1 is attached to the lower end via a support member 17.
8 are rotatably connected to a pin 19. A pair of support members 20 are attached to the lower surface of the flexible table 18 at a predetermined interval in a direction perpendicular to the conveyance direction of the frame. Rotating shafts 21 are rotatably supported between the supporting members 20, and a pair of clamp arms 22 each having a hook portion 22a protruding from the inside of the tip are fitted onto each of the rotating shafts 21 at regular intervals in the axial direction. are inserted and each rotating shaft 2
1 are interlockably connected via links 23, 24, etc., and one rotating shaft 21 has a piston rod 26a of a clamp cylinder 26 rotatably supported on the upper surface of the flexible table 18 via a cylinder bracket 25. The clamp arm 22 is rotatably connected via a link 27, and is opened and closed about the rotating shaft 21 by the expansion and contraction of the clamp cylinder 26. Guide rods 28 are provided on both sides of the frame alignment cylinder 12 and have their lower ends fixedly connected to the upper surface of the lifting table 13 via a bracket 29, and are slidably inserted into the guide tube 30 attached to the upper frame 3. The lifting table 13 is prevented from rotating in a horizontal plane.

Next, to explain the operation of the device configured as described above, the upper frame 8 and the lower frame 9 holding the molding molds are conveyed on the conveyor 7 in the order of the upper frame 8 and the lower frame 9. When the frame alignment cylinder 12 is extended, the elevating table 13 and the flexible table 18 are moved to a position directly below the clamp arm 22.
etc. are lowered and the hook portion 22a of the clamp arm 22
is located below the upper flange portion 8a of the upper frame 8 and stops.

Next, the clamp cylinder 26 is extended to close the pair of clamp arms 22, and the frame matching cylinder 12 is retracted to move the upper frame 8 holding the mold into the clamp arms 22.
While being supported by the hook portion 22a of the frame via the upper flange portion 8a, it is lifted up to a predetermined height that does not interfere with the lower frame 9. Subsequently, the lower frame 9 is moved onto the conveyor 7 by the operation of a push cylinder (not shown).
When the upper frame bush 10 and the guide pin 6 are fed to the corresponding position, the guide pin cylinder 5 is extended, and the guide pin 6 rises and passes through the through hole 9d of the lower flange portion 9b to the lower frame. It is inserted into the pin hole of the bush 11. Next, by the extension operation of the frame alignment cylinder 12, the lifting table 1
3 and the adjustable table 18 are lowered, the upper frame bushing 10 is fitted into the guide pin 6 and the lower shaft 10a of the upper frame bushing 10 is moved to the lower frame bushing 1.
The upper frame 8 and the lower frame 9 are fitted into and positioned in the recess 11c of No. 1, and the upper frame 8 and the lower frame 9 are aligned. When aligning the frames, the flexible table 18 has a mechanism that allows it to move freely relative to the lifting table 13, so even if the centers of the upper frame bushing 10 and the guide pin 6 are slightly misaligned, the upper frame bushing 8 will be aligned with the guide pin 6. It is inserted and guided into the recess 11c of the lower bushing 11 and positioned. After the frames are aligned, the guide pin 6 is lowered and removed from the upper frame bushing 10 and the lower frame bushing 11 by the retracting operation of the guide pin cylinder 5. After that, by retracting the frame alignment cylinder 12, the elevating table 13 and the flexible table 18
rises and prepares for the next frame alignment operation,
A pair of upper and lower frames 8 and 9 holding molding molds are conveyed on a conveyor 7 to a pouring station (not shown) by the operation of a pusher cylinder (not shown). Thereafter, repeat the above operation.

As is clear from the above explanation, according to the present invention, the upper flange of the upper frame can be a blind flange. Since it does not fall into the bushing, there is no problem with frame separation, or the pins of the pattern plate do not fit into the frame bushing during molding. The contributing effects are significant.
