Description

Technical Field

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

[0002] A die-casting machine is a machine used for pressure casting, including a hot press chamber and a cold press chamber, which are later divided into vertical and horizontal types. The die-casting machine hydraulically injects molten metal into the mold under pressure for cooling and forming. After the mold is opened, a solid metal casting can be obtained. It was originally used for die-casting lead type.

[0003] For example, a Chinese utility model patent (CN210282266U) discloses a robot for taking out parts from a die-casting machine, which solves the problem that the die-casting parts produced by some die-casting machines are generally taken out manually, which is time-consuming and labor-intensive, affecting the working efficiency of the die-casting machine;

[0004] When using the above technology, it was found that the following technical problems exist in the prior art: the robot clamps the die-castings through a clamping process in the horizontal plane. This clamping method is relatively simple. When encountering more complex die-castings that need to be clamped from a specific angle, it may not be able to clamp or the clamping effect is poor and it is easy to fall; on the other hand, the robot moves the die-castings to pick up and place them through rotational movement in space, which occupies a large space. The movement amplitude of the robotic arm during movement is large, requiring a large space, and it only uses rotational movement, which has certain limitations when used. For this reason, we design a pick-up machine to provide another technical solution to the above technical problems. Utility Model Content
