Hi Adalton,
Looks very professional. Personally, I would remove the springs and place weights on the cross bar, otherwise as the cheese is pressed, it will move away from your follower, lessening the press weight. I also like weights because you know how much you've put on, with the springs, how much pressure you're applying is more guess work than known (making it harder to reproduce later; 5 turns isn't the same if the springs are worn, etc).
Now, my prsonal preference aside, this is a common design and, since you've made a gouda with it already, clearly it works. In the end, it's more important to go with what works for you.
Oh, your molds. Do they have drain holes in the sides? They appear to be solid. If you've made those, it might be worth drilling small holes (1-2 mm diameter) in columns, (roughtly 2 cm apart in the vertical, with each column about 2 cm away from each other, but the holes offset ; i.e. column 1 has it's first hole at 1cm from the edge, column 2 is at 2 cm, colum 3 starts at 1 again, and so forth)
