Description

2, Installation according to paragraph 1, 1 st, so that the drive is bounced, the cushion pad is mounted on a swing frame fixed in the working position by a safety pin, and the plate of the extrusion mechanism is clod

pivotally mounted on the rod of the drive, which cantilever is mounted with the possibility of rotation on the U-shaped frame above the window for the passage of the clod of the working platform of the slide.

,,. I /, The invention relates to a foundry industry and can be used to knock out casting molds. A known device for the knockout of mold forms, including the collider of the cast forms, knock-out grids and handlers mounted on trolleys interconnected. The tool for removing castings is equipped with a drummer ij. Closest to the proposed technical essence and the achieved effect is a pass-through embossing installation, including the flask facing from the platform of the casting conveyor, with the window for the coma passage, on which the frame is equipped with a pneumatic cylinder for pushing, a mechanical grille with bars, which installed profile brackets for Interaction of the longitudinal surface of the head with the trunnion) parts of the lower part of the flask at the time of its exit from the n daymaking cylinder of pushing, become empty Gen. them on the conveyor. return 2. A disadvantage for known installations is the low durability of the flasks, because of the large size of frequently repeated shock contact loads, due to the influence of the profile brackets on the limited areas of the trunnion lower parts of the flasks, the latter are broken down and become unusable. In addition, due to the short duration of the impact of the vibrating lattice on the flasks, cleaning their walls from the mountain of the earth is insufficient. When installing / such a dirty flask on the model plate of the molding machine, the flames of the burned earth are poured on, which leads to a casting marriage. The purpose of the invention is to increase the rigidity of the tooling, to improve the cleaning of the burned earth, as well as to increase the reliability of the installation. This goal is achieved by the fact that the gate of the flasks installed on the platforms of the casting conveyor, with the window for the passage of the coma, the mechanism squeezing a mechanical vibration grid with a drummer attached to it, close to each other in the teeth (two two articulated driving platforms, one of which is equipped with a bogie platform for contact with a drummer with a shock-absorbing surface, another vertically rotated with an understated relative to the working platform, a horizontal plane on which the limiting stops are fixed. its actuator stem, cantilever mounted with the possibility of rotation on the U-shaped frame above the pknom for the passage of a working platform clod figure 1 shows the installation, top view ;; figure 2 - view A on rig 1; in FIG. 3, view B in FIG., and FIG. 4, view B in FIG. The installation contains a slide 1 consisting of a working platform 2, including a plate 3, provided with directions 1, 4, frames 5, sub-nodes b, brackets 7 with conical sockets 8, piston drives 9, fender 10, vertical turning platform 11 including a hinge 12, a plate 13 with restrictive stops 14 and a drive 15 mounted on a hinge 16 and attached with its stem to 17, and stops 18. The installation also contains a mechanism for extruding a coma 19 consisting of a plate 20 hinged on the drive rod 21 cantilever mounted on U-frame 22, flasher 23, consisting of a buffer 24 fixed at the end of the piston actuator stem 25, frame 26, hinge 27, safety pin 28, air sensor 29 on the bracket 30. t In addition, the installation contains a grid of 31, timber 32 which is mounted drummer 33, equipped with a shock-absorbing surface, flask 34, empty conveyor return conveyor 35, casting conveyor 36.

Passing knocked pja installation is as follows. The buffer 24, acting on the flask 34, moves it to the working platform 2 of the slide 1. The pneumatic sensor, controlling the front position of the buffer 24 (not shown), gives the command to retract it, turning on the actuators 9 and 21 to lower the working platform 2 of the slide 1 and the plate 20 of the mechanism of extrusion 19, as well as the inclusion of a time relay not shown)

The working platform 2, turning in the bearing units b downwards, begins to contact the firing platform 10 with the shock-absorbing surface of the firing pin 33, the transmitting platform 2 and the box on it

34 oscillations from the working vibrator-31.

Simultaneously with the lowering of the free end of the working platform 2, the drive rod 21, lowering down, pulls out a plate from the flask with a plate 20, accelerated the knockout process. .

After a certain time has elapsed (2-3: s), the time relay instructs the drives 9 and 21 to lift the working platform 2 and the plate 20 of the extrusion mechanism upwards, and also to the drive 15 of the vertical-rotary platform 11 of the slide 11 on its noBOipoi, with the previously installed an embossed flask on it (not shown) .;

At the beginning of the rotation of the plate 13 of the nnaiform 11, the flask 34 is held by the Uibers 14, and at the end of the turn, stability is resisted, the flask 34 is tilted onto the conveyor belt of the flask

35j and platform 11 returns to its original position, mounted. using the stops 18 to the horizontal position.

At the approach of the next flask in the zone of action of the PNB sensor 29 cycle

the knockout operation is repeated.

The use of a slit made of the above construction reduces the contact shock loads on the flasks, thus increasing their durability, and allows them to withstand the optimal time of knocking out, which affects the quality of cleaning the flasks from the burnt earth.

The use of a vertical swiveling platform makes it possible to turn over the flasks, which is necessary for the technical process, which in turn helps to further clean them, because the flasks get additional shock absorbing drops when they tilt the return conveyor belt onto the belt, due to which they are further cleaned from the burnt ground.

Cantilever fastening of the drive of the flashing mechanism on the U-shaped frame with the possibility of its rotation, as well as fastening the drive of the stadivka-. The body of the flasks on the rotating frame with its safety pin in the working position protects these mechanisms from damage.

For example, when jamming

The piston of the drive of the extrusion of the coma located below, when advancing the flask, lastly turns the drive, and if for the same reason, the pusher buffer does not return, then when subjected to it, the next flask also drives the drive, cutting off the safety pin.

/ To restore these mechanisms to their working position, a mini-glum of time will be required.
