Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a casting material taking mechanism of a die-casting machine tool. Background Art

[0002] A die-casting machine is a casting machine that hydraulically injects molten metal such as aluminum into a mold under pressure, cools it and forms it, and then a solid casting is obtained after the mold is opened. Existing die-casting machine tools have two feeding methods: manual feeding and mechanical feeding. Manual feeding is prone to fatigue, has low feeding efficiency and poor safety, but can accurately determine whether feeding is completed by visual inspection. Mechanical feeding has high feeding efficiency and good safety, but it is difficult to determine whether feeding is completed.

[0003] The prior art (CN214263835U) discloses an aluminum casting material picking mechanism for a die-casting machine tool, comprising: a manipulator, a material picking assembly, a controller and an electrode. By arranging the material picking assembly at the end of the manipulator, the material picking assembly can be moved in the up and down, front and back, left and right directions under the drive of the manipulator. By making the clamping surface of the clamping jaws of the material picking assembly an insulating surface and arranging the electrode on the clamping surface, the electrode is electrically connected to the controller. When the clamping jaws are closed, the on-off result of the electrode can be fed back to the controller, so that the controller can clearly know whether the clamping jaws have completed material picking, so as to proceed to the next step. The scheme has an ingenious structure and a simple arrangement, and makes full use of the conductive properties of the aluminum casting itself. Only when the clamping jaws clamp the aluminum casting can the electrode be turned on, so that the controller can accurately judge whether the material picking is completed, so as to proceed to the next step. The automation degree is high and the material picking effect is good.

[0004] With the above method, as long as the upper and lower jaws drive the two electrodes to slightly contact the casting, the two electrodes will be turned on, and the controller will determine that the material removal is completed, so as to proceed to the next step. However, this cannot ensure that the upper and lower jaws have clamped the casting, resulting in the casting being likely to fall off from between the upper and lower jaws because it is not clamped when the next step is performed.
