14th week

FERNANDO HUMANES

This week we continue with the design of the scrap evacuation mold. We have to assemble this mold in our die and position it in the press. First I made a mold, and when I received the clarla from an expert in foundry mold design, I realized that I had to improve the first design.

To improve this first design, we made some important changes.

First we perform calculations to size the flasks and the mold filling channels.

The mazarotas are useful that are placed to avoid the formation of rechupes in the pieces.

The filling channels are dimensioned and I put a larger diameter, so we will perform a uniform filling and prevent the liquid from solidifying as uniformly as possible.

I have also placed an iron plate, this makes cooler and alluda to solidify evenly.

the mazarotas are placed to their correct measure, in this way we avoid that the neck of the mazarota solidifies before the mazarota.

This week we have continued working with the base made from a foundry. After having the design finished with all the well located material extraction ramps we have begun to position the filling tubes and the mazarotas in the base. This is so that at the time of filling it is the last thing to cool down and so be it in the flasks where the defects of the piece appear.

To place the flasks and the filling part we had at our disposal some ppt-s which had information about it. In addition, an expert has also come to class that we have been able to ask.

This week we continue with the design of the mold. We have to finish the final design, making the calculation of all things, like "mazarotas" to avoid "rechupes", where place the flask and the filling part and nerves.

Our first design was not okay, but with the help of an expert in foundry we solve all our problems we can have and make a redesign to improve the finall result and have a functional and viable final result.

We made some important changes this week.

We made calculations of the flasks and the mold filling channels.

The mazarotas that are  to avoid the formation of Little holes in the pieces.

The filling channels are dimensioned, so we will perform a uniform filling and prevent the liquid from solidifying as uniformly as possible.
