Abstract

The invention relates to foundry, in particular, to chill casting. The purpose of the invention is to expand technological capabilities and improve service conditions. The device works on three programs. With simultaneous removal of the lower rod 5 and ejection of the casting 28, the oil pressure is supplied to the rod end of the power cylinder 6. The rod 12 moves down, removes the rod 5, until the shoulder stops in the stop, after which the cylinder body 7 moves up and the ejectors remove the casting from the fixed plate 1 When the rod is removed separately and the casting is pushed out, the latch 10, which keeps the casing 7 from moving, comes into action. To remove the molds, the pin 25 connects the stopper 9 and the retainer 10 of the housing 7. The sleeve 8 is moved by the cylinder 11 along the guides, while the rod and the ejectors come out of engagement with the power cylinder 6. The mold is ready for disassembly. 4 il.

Description

The invention relates to casting, molding, and in particular, to chill casting.

The purpose of the invention is the expansion of technological capabilities and the improvement of service conditions.

FIG. 1 shows the device section; in fig. 2 shows section A-A in FIG. one; in fig. 3 section bb in fig. one; in fig. 4 — node 1 in FIG. one.

The device consists of a fixed pinched 1LITA 1 mounted on a bed 2, a plate 3 with ejectors 4, a lower rod 5, a power cylinder 6, the housing 7 of which is placed with the possibility of vertical movement in the sleeve 8, the stroke limiter of the housing 7, made in the form rocker arm 9. retainer 10 of the body of the power cylinder 6, made in the form of a slider cylinder 11, fixed stationary on the frame 2. Restrictor 9, made in the form of a rocker arm mounted on the sleeve 8. As the upper stem stem 12 serves as a collar of the lower rod 5, and the lower limiter of the housing 7 is a pint 13. A sleeve 7 is installed in the guides 14 and can be fixed in them with bolts 15. The mountains 10 are fixed to the UJTOKOM 16 of the cylinder 11 by a lock 17. The housing 7 is connected through crown 18 to the stove 3 the tails 19 and the grippers 20, and the stem 12 with the lower rod 5 through the shanks 21 and 22, the half-holes 23 and the cartridge 24 enclosing them. The stopper 9 is equipped with 1 strings 25, which can be installed in the holes 26 and 27, made respectively in the rocker arm 9 and lock 10, ensuring the lasting of the latter relative to the arms . Casting 28 is formed by noluquils 29 and: 50 and movable nodkoklilnoy nlikoy I.

The device works as follows.

For castings, the production technology of which donuts the simultaneous extraction of the lower rod 5 and the ejection of the casting 28, the rod 16 of the cylinder 11 is retracted to the far right. yuzheniyu, with fixation I 1 (1 frees up the body 7 of the sily si-. 11: ndra 6.

After the metal is poured with the melt, the nukokils 29 and 30 are opened and the oil pressure is applied to the rod of the power cylinder 6. The rod 12 moves downwards and the bottom rod 5 moves out of it, while the end face of the rocker arm 23 is tilted to the upper plane of the rocker arm 9, the body 7 is displaced nBSr.ch | The ejectors 4 remove the ebb-to-28 from the fixed tuck-on plate 1, while the casing moves to the lower plane of the rocker arm 9.

After preparing the chill mold, oil is fed to the assembly in the rodless cavity CM.KJBOiT of the cylinder 6. The rod 12 moves to the top). and brings the lower rod 5 to the uno | 1a of the collar into the fixed turf (hing-nuk) plate 1, the housing 7 is turned down.

lowers the plate 3 to its original lower position, while the body comes to stop with a screw 13. The cycle is over.

In order to produce castings that require separation of the operations of extracting the lower rod 5 and pushing the casting 28, the rod 16 is extended and the latch 10 is brought into contact with the housing 7 of the power cylinder 6.

For disassembling the hot melt chill mold, the oil pressure is supplied to the piston chamber of the cylinder 6. Since the housing 7 is fixed and cannot move, the rod 12 moves down, pulls the lower rod 5 and the oil pressure in this cavity of the cylinder 6 is relieved. Then, the semicolons 29 and 30 are opened, the oil pressure is fed into the rod end of the cylinder 11 and the rod 16 removes the retainer 10 and releases the case 7. The pressure is resumed into the rod end of the cylinder 6, the body moves upwards and the ejector 4 removes the casting 28 from the stationary podkokilny plates 1.

To assemble the chill molds, the oil pressure is supplied to the brushless cavity of the cylinder 6 and the lower rod 5 is moved up and the plate 3 down, i.e., into their working position. The oil pressure is supplied to the rodless cavity of the cylinder 11 and the lock 10 fixes the housing 7.

Then the cycle repeats.

To extract the chill molds from the position shown in FIG. 1-3, the pin 25 is rearranged into coaxially arranged holes 26 and 27, the upper rod 5 is fixed (not shown), the bolts 15 are unscrewed and the sleeve 8 is released, the cartridge 24 is lifted up and the half-holes 23 are pulled out. the rod 16 moves the sleeve 8 but guides the bed 14, while the shanks 19 come out of the engagement with the grips 20 of the plate 3. The mold is ready for dismantling.

From this position, by removing the chill and sn in the lock 17, it is possible to remove the liner with the power cylinder 6 but guiding 14 from the bed 2 to the side, G1 protivopoto, burner cylinder 11.

Similarly, the sleeve 7 with the power cylinder 6 can be removed without removing the chill tooling, once the pre-brush 12 with the lower rod 5, and the latch 10 with the rod 16 of the cylinder 11.

The proposed device design allows independent disassembly and removal of the chill tooling and power drive.

Due to this, a reduction in labor intensity during disassembly and maintenance of the device is achieved, its technological capabilities are expanded.
