Technical Field
[0001] The present application relates to the field of mold manufacturing and maintenance processes, and in particular to a mold opening device. Background Art
[0002] During mold manufacturing and maintenance, assembly and disassembly, as well as opening and closing, are routine operations. These tasks are typically performed using a standard bench and a crane (a common starting device in production workshops) by prying or hammering the mold open. This method is labor-intensive, inefficient, and lacks precision, and can easily damage the mold due to imbalance during opening and closing.
[0003] To improve work efficiency and protect the mold, a special workbench has been developed to standardize the mold assembly and disassembly process. Manual assembly and disassembly is feasible for simple molds. However, due to the complex internal mechanisms of most molds, the friction between the components (parts) is significant and unevenly and randomly distributed, making opening and closing the mold very difficult.
