Description

Technical Field

[0001] The utility model relates to the technical field of automated equipment operation, in particular to an automatic mold core taking device for a flat frame annular production line. Background Art

[0002] The existing technology generally uses manual carts or forklifts to operate large molds. This method is inefficient and has no safety guarantee, which poses great risks. Our company has developed a flat frame annular production line that can automatically transport molds. The mold can be transported to the mold opening area for mold opening. However, after the mold is opened, due to the special process, the mold core is embedded in the inner wall of the product, which is difficult to remove and requires multiple attempts. The usual method is to manually knock the mold core off the surface of the product. This method is inefficient and will cause surface scratches after the core falls off. Secondly, during the knocking process, the side wall of the product will be scratched and damaged. Utility Model Content
