Description

Technical Field

[0001] This utility model relates to the field of fixing devices, and more specifically, to a fixing device for automotive parts forming molds. Background Technology

[0002] The booming and rapid development of the automotive industry has driven the rapid development of many other industries. Among these, the rapid development of the automotive industry has primarily driven the rapid development of automotive parts companies and automotive mold companies. The development of a new car requires more than 20,000 automotive parts. The research and manufacturing process of these parts requires a large number of molds and fixtures, with the demand for molds being the largest.

[0003] A search revealed that Chinese patent CN211135226U discloses "A Die for Easily Disassembled and Assembled Automotive Parts Processing," which includes an upper die. The bottom surface of the upper die is fixedly connected to an upper forming block via a fixing square plate. Both the upper die and the upper forming block are divided into four equal parts. The edges of each upper die and upper forming block in contact are fixed by the fixing square plate and screws. Each upper die and upper forming block has sliding rods at its four corners. This die for easily disassembling and assembling automotive parts processing, through the arrangement of the upper die, upper forming block, fixing round plate, and fixing square plate, can stably fix and disassemble the upper die and upper forming block. The springs provide good shock absorption, preventing impact when the upper and lower forming blocks contact. The fixing screws securely fix the lower die and lower forming block. The snap-fit ​​device allows for secondary fixing of the four upper forming blocks. However, the following drawbacks still exist:
