The UCMSC65 series is a commonly used suspension mechanism in automotive moldings. This utility model patent technology is primarily fixed from above to the lower mold base of the automotive molding, with return limit blocks and stroke limit blocks respectively set on the sides of the moving wedge at both ends of the upper mold base; a return spring is provided on one side of the moving wedge; a punch with an angle to the horizontal plane is set at one end of the lower end of the moving wedge; another end of the lower end of the moving wedge has a guide slider with an angle to the horizontal plane, which is embedded with oiled graphite. The lifting wedge mechanism can reduce the molding process, decrease the overall dimensions of the mold, and lower the cost of stamping and maintenance for the mold.
