Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a mold opening and closing fixing clamp of an automatic mold opening and closing machine. Background Art

[0002] When the mold opening and closing machine is in operation, it processes the material by closing and opening the mold. Specifically, the mold opening and closing machine injects a fixed amount of molten material into the mold cavity by controlling pressure and speed. The mold is then closed by the mold clamping device, ensuring reliable mold closure and the ejection of the finished product.

[0003] When the mold opening and closing machine is working, the mold parts need to be clamped using the clamps on it. However, the current clamps usually drive multiple clamping mechanisms to move through multiple different driving mechanisms (upper ejection cylinder, cylinder, etc.), so that multiple different clamping mechanisms can fix the mold parts from multiple directions. However, since different driving mechanisms may have some errors and delays when in use, the mold parts cannot be fixed exactly in the center position of the clamp, which may cause some errors when opening and closing the mold, reducing the precision of the mold.
