Description

Technical Field

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

[0002] The die-casting machine is a machine used for pressure casting. Its working principle is to hydraulically inject molten metal into the mold under pressure to cool and form. After the mold is opened, solid metal castings can be obtained. It is widely used in the production of automotive parts.

[0003] After checking the public (announcement) number: CN219563135U, a pick-up gripper device for a die-casting machine is disclosed. This technology discloses "a pick-up gripper device for a die-casting machine, including a top plate, a gripper device body is arranged at the bottom end of the top plate, a manipulator is installed at the bottom end of the outer wall of the gripper device body, a fixed block is fixedly connected to the top of the gripper device body, a fixed frame is fixedly connected to the top of the top plate, one end of the fixed block passes through the interior of the top plate, a plug-in hole for plugging from bottom to top at the top of the fixed block is provided inside the fixed frame, and a first groove is provided on one side of the inner wall of the fixed frame" and other technical schemes, which have "the pick-up gripper device for a die-casting machine facilitates the clamping of the inner limit block of the pick-up gripper device for a die-casting machine with the inner part of the fixed block through the mutual cooperation between the components during use, so as to realize the rapid removal of the gripper device body in the pick-up gripper device for a die-casting machine, and improve the removal efficiency of the pick-up gripper device body for a die-casting machine when maintenance is required" and other technical effects;

[0004] In the die-casting production process of automotive parts, especially when dealing with small accessories such as automotive balance weights, due to the large number of parts, the method of grabbing one by one is obviously inefficient. However, on the current production line, if multiple grippers are used for batch grabbing, there is a key problem: the spacing between these grippers cannot be flexibly adjusted. This limitation means that the production line can only produce automotive balance weights of specific sizes or specifications. Once the product specifications need to be changed, the production line has to frequently replace the grippers, and may even require large-scale modifications to the entire production line. This not only greatly reduces production efficiency, but also seriously affects the flexibility and adaptability of the production line, causing trouble to the overall process of automotive parts production.
