Clamping and positioning module

A clamping and positioning module, comprising:

• an upper base plate and a lower base plate locked with each other, wherein the upper base plate has a first half mold cavity disposed therein, wherein the first half mold cavity has an embedding opening provided thereon and communicated with an outside, wherein the lower base plate has a second half mold cavity terminated by a wall member and disposed therein opposite to the first half mold cavity of the upper base plate, wherein the first half mold cavity and the second half mold cavity respectively have an air flow channel arranged therein, wherein the base plate has two air guide ports arranged thereon, wherein the air guide ports are respectively connected with the air flow channels;
• a plurality of clamping and positioning units, respectively mounted and positioned between the first half mold cavity and the second half mold cavity, wherein the clamping and positioning unit comprises a movable seat mounted at the embedding opening, such that the movable seat is maintained in a same plane as an upper end surface of the base plate, a center of the movable seat having an embedding hole to allow a clamping rod of a workpiece to be processed for insertion and embedment, a clamping member for clamping the clamping rod provided around the movable seat, a piston seat provided at a bottom of the movable seat, a plurality of elastic members for supporting provided around the piston seat corresponding with the mold cavities, and a base body provided at a bottom of the piston seat for closing the embedding hole and jacking up the clamping rod;
• said wall member of said lower base plate for sealing and closing the installation opening and to position and retain the clamping and positioning unit in the first half mold cavity and the second half mold cavity;
• and
• a gas introduced into or discharged from the air flow channels through the air guide ports, so that the clamping and positioning unit clamps or releases and pushes the clamping rod.
