摘要： The present invention relates to an improved clamping mechanism for use in injection molding machines and similar pieces of equipment where it is desired to apply a clamping force to particular components. The clamping mechanism of the present invention employs at least one spaced apart brake plate mounted to one component and a braking unit for engaging the brake plates. The braking unit has at least one pair of brake pad linings surrounding the brake plates and at least one piston-cylinder unit for causing frictional engagement between the respective brake pad linings and the brake plate(s). When the brake pad linings grip the brake plate(s), the braking unit becomes locked to the components to which the brake plate(s) are attached. The clamping mechanism of the present invention may be employed on simple injection molding machines as well as TANDEM.RTM. injection molding machines.
