In the automatic pressing device for casting, a first sensor is mounted on the lower end side of the upper plate in the conveying direction of the molding box; and a second sensor corresponding to the upper plate is arranged below the fixed plate.
In the automatic pressing device for casting, the limiting mechanism is located on the front side of the conveying direction of the molding sand box, so that the movement of the molding sand box can be prevented.
In the automatic pressing device for casting, the limiting mechanism can extend up and down, and when the limiting mechanism is completely retracted, the limiting mechanism is completely retracted into the rack, so that the transportation of the molding box is not blocked; when extended, can create a dam for the mold flask.
Compared with the prior art, the utility model discloses an install stop gear on automatic closing device, touch stop gear and trigger travel switch when the molding sand box motion after, the delivery track stops to carry, and closing mechanism pushes down and compresses tightly the operation. The position of a pressing plate of the pressing mechanism is relatively consistent with that of the spacing molding sand box, and accurate alignment can be achieved during pressing operation. The working state of the pressing mechanism is obtained through the second sensor, and after the pressing operation of the pressing mechanism is completed, the limiting mechanism retracts into the rack, and the conveying track starts to operate to convey the molding box. Acquire the molding flask position of hold-down mechanism below through a sensor, thereby after the perception molding flask, stop gear stretches out and carries on spacingly to the molding flask. In the whole molding sand box pressing operation process, the limiting mechanism is adopted to limit the molding sand box, so that the automatic alignment of the pressing operation is realized, the manual alignment operation is not needed, and the working efficiency of the pressing operation is improved. The compaction mode does not need manual operation, the instability of the manual operation is eliminated, the compaction effect of the compaction operation is more stable, and the stability of the product quality is improved.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. An automatic pressing device for casting is shown in figures 1 to 3 and comprises a frame 1, wherein two sides above the frame 1 are provided with support rods 2, and fixing plates 3 are arranged on the support rods 2; a pressing mechanism 4 is arranged below the fixing plate 3; a limiting mechanism 5 corresponding to the pressing mechanism 4 is arranged on the upper side of the frame 1, and a travel switch 51 is arranged on the limiting mechanism 5; the pressing mechanism 4 comprises a motor 41 arranged above the fixing plate 3, the lower part of the motor 41 is connected with a pressing plate 44 through a hydraulic telescopic rod 42, and a telescopic rod 43 is arranged between the fixing plate 3 and the pressing plate 44.
The pressing plate 44 comprises an upper plate 441 positioned below the hydraulic telescopic rod 42 and a lower plate 442 positioned below the upper plate 441; the upper plate 441 and the lower plate 442 are both rectangular solids, and the length and width of the cross section of the upper plate 441 are greater than those of the cross section of the lower plate 442; the lower plate 442 corresponds to the sand box, ensuring complete compaction.
A first sensor 62 is arranged below the upper plate 441, and the first sensor 62 acquires the position of the molding box; a second sensor 61 corresponding to the upper plate 441 is arranged below the fixing plate 3, and the second sensor 61 acquires the position of the pressing plate 44.
The limiting mechanism 5 is located on the front side of the conveying direction of the sand box, and when the sand box is blocked by the limiting mechanism 5, the travel switch 51 is activated.
The limiting mechanism 5 can stretch up and down, and when the limiting mechanism 5 is completely contracted, the limiting mechanism 5 is completely retracted into the rack, so that the transportation of the molding sand box is not blocked; when extended, can create a barrier to the mold flask.
The working principle is as follows: as shown in fig. 1 to 3, the conveying rail is located above the frame 1 to transport the molding boxes, and the stopper mechanism 5 is retracted within the frame 1. When the molding sand box is sensed by the first sensor 62 after moving into the pressing device, the stopper mechanism 5 protrudes from the frame 1 to block the molding sand box. When the stroke switch 51 of the sand box contact limiting mechanism 5 is turned on, the operation of the conveying track is stopped, and the sand box is stopped in front of the limiting mechanism 5. The pressing mechanism 4 starts to perform pressing operation, the motor 41 drives the hydraulic telescopic rod 42 to extend, the pressing plate 44 presses down and presses molding sand in the molding flask, after the pressing operation is completed, the motor 41 drives the hydraulic telescopic rod 42 to contract, the pressing plate 44 rises, and the second sensor 61 acquires position information of the pressing plate 44. When the hold-down plate 44 is fully returned to its original position, the stop mechanism 5 is retracted into the frame 1 and the conveyor track begins to operate to deliver the sand box to the next station.
