Abstract: An injection molding heat removal sensing and control system and method are provided for determining and controlling a heat transfer rate for a mold in a molding machine. The system includes an inflow temperature sensor for sensing an inflow temperature for coolant provided to the mold, an outflow temperature sensor for sensing an outflow temperature for coolant exiting the mold, and a flow rate sensor for sensing a flow rate for coolant through the mold. The electronic processor is also configured to calculate a heat transfer rate for the mold from the inflow temperature, the outflow temperature, the flow rate for the coolant, and the calculated mass and the temperature of the molten plastic. The processor determines a time lag between when heat enters the mold and when heat is removed by the coolant and pre-emptively adjusts coolant flow rate to provide uniform heat transfer throughout a molding cycle. The heat transfer rate and total energy removed can be determined and provided on the display.

Abstract: An improved puller apparatus for pulling various articles, including automotive pitman arms, includes a puller frame having a base and at least one upstanding arm extending therefrom, the arms having inwardly extending gripping projections for transmitting pulling force to the article being pulled, the base having an aperture extending therethrough for receiving pushing means, which pushing means include an actuation means disposed at a portion of the pushing means proximal to the article being pulled, such that a user may engage the actuation means at a position within the puller frame to axially move the pushing rod against a relatively stationary interiorly disposed object around which the article to be removed is mounted. The pushing force applied against the interiorly disposed object creates a corresponding reaction force in a direction opposite the pushing force, which reaction force is transmitted to the article being removed via the gripping projections on the puller frame.
