A modular tooling receiver that includes a wall having a port that extends through it, an engaging member that is movably disposed in the port, and a lock actuator that is disposed on a first side of the wall. The lock actuator is moveable between a first position in which the lock actuator urges the engaging member in a first direction defined from the first side of the wall to a second side of the wall and a second position wherein the lock actuator permits the engaging member to move in a second direction defined from the second side of the wall to the first side of the wall. A first biasing element biases the lock actuator toward the first position. A damper controls a rate of motion of the lock actuator from the second position toward the first position.
