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.

13th week

FERNANDO HUMANES

This week we have begun to design each group member his sketch for the design of the mold.

Nagore has given us some rules that the mold has to meet when designing and then melt it in foundry. The mold we designed is in accordance with the die we designed in the previous challenge, since it has to respect the measures of the die so that the die rests on the mold.

We have also received a talk from an expert in casting parts and molds, this person has given us some guidelines to follow and some good advice, that if we fulfill them the design will come out perfect.

On Friday we made a visit to an Elorrio smelter, it is called Betsaide.

The visit was very interesting and very contributing to the design of our mold.

In the final design, which will be the group design, we have to position the flasks, the filling system and the mold feeding system.

The mission of the mazarotas is to avoid the rechupes of the pieces and the complete and uniform filling.

After designing the mold we have to design it with a 5% oversize, since when the liquid cools it contracts.

This is the second week of the new challenge. In these five days we have continued designing the base. At the end of the initial design we have inserted it and made an assembly with our die.

After making the assembly we have chosen one of them through a matrix to make some small changes and improve it. After changing the method of leaving the remaining material, we design some flasks and the entrance for the liquid to be able to simulate the filling.

On Thursday of this week we only had two hours to continue with the project because later we went to Elorrio to pay a visit to the Betsaide company in which they showed us how a foundry worked.

This is the second week of the new challenge.This week we continue with the design of the base. We make the assembly of the base to the press and to the die, and take first look of how it fit one each other. 

After each meamber of the group have design his own base, through a design matrix with some parameters we choose one of the 5 different degigns.

On Thursday we went to Elorrio to visit Betsaide company where they show us how a foundry works

This week we had to design a sketch for the design of the mold.

 The mold we designed, is in has to go with the die that we made on the prject before, it goes below the dies that we made.

A man came this week to give us a lesson about doundition a few tips for the designing. He helped us a lot with the explanaitions that he gave us.With all the designs that we made, we had to pick one out of evey group and final design, and design the flasks, the filling system and the mold feeding system.

After designing the mold we have to design it with a 5% oversize, since when the liquid cools it contracts that way when it cools, it increases.
