AI Technical Summary
Technical Problem
In the current production of oil-impregnated bearings, the fixed installation of molds makes it impossible to replace mold components individually, resulting in long downtime for replacements and affecting work efficiency.
Method used
An oil-impregnated bearing forming mold was designed, including a base, a detachable middle mold assembly, an upper mold assembly, and a fixing assembly. The mold can be quickly installed and disassembled through structures such as insert rods, sockets, pressure blocks, and springs, and supports the quick replacement of the middle mold base and punch.
Benefits of technology
It enables rapid mold replacement, adapts to different bearing production needs, and improves production efficiency.

Abstract
This application discloses an oil-impregnated bearing forming mold, belonging to the field of mold technology. It mainly includes a base; a middle mold assembly, which has a middle mold seat suitable for filling powder; an upper mold assembly; and a fixing assembly, which is mounted on the base. The fixing assembly includes: two sets of mounting blocks, which are mounted on the middle mold seat and have insert rods mounted on them, with slots on the insert rods; two sets of sockets, which are threaded onto the base and have sliding grooves inside and circular slots on their surfaces; two sets of pressure blocks, which are slidably disposed inside the sliding grooves, and both the pressure blocks and the sockets have through holes; and two sets of springs, which are connected between the inner wall of the circular slots and the pressure blocks. The oil-impregnated bearing forming mold of this application allows for quick installation and disassembly of the middle mold assembly through the fixing assembly, facilitating the replacement of the middle mold seat according to actual needs, and adapting to bearings with different production requirements, achieving a quick mold change capability.
