Abstract

In the green sand molding process olivine sand is compacted into flasks that are used for the molding and pouring process in a foundry. These sands are difficult to remove after the pour has been made. In Central Washington University’s foundry the sands are currently being removed with handheld rams. To improve on this process a Foundry Flask Punch Out machine was designed. The machine was designed to utilize a wall mounted rack and pinion style press. The supporting elements of both the flask and press were engineered with deflection requirements in mind. The machine was made to fit into the current sand handling system without any addition modifications. Testing the Foundry Flask Punch-Out machine shows that it is and improvement from the previous process. The machine removes sand efficiently and with little effort. This machine also improved of safety as it removes interaction with hot foundry sands and castings.
