The name is Ammonium amminetrichloridoplatinate(II). Why is it platinate and not platinum?

It is platinate because the coordination compound [Pt(Cl3)(NH3)] has an overall -1 charge and when there is a negative charge on the coordination compound, the metal name changes to -ate at the end.

Whenever a complex is anionic, meaning that it has an overall negative charge, the ending of the metal will be -ate.

The ending of a metal's name always changes to -ate when it the compound is anionic, or has a negative charge.

You use platinate instead of platinum because the charge of the overall complex is negative, so its an anion. The rule is that when the charge of the complex is an ion, you end the metal with -ate.

Since the ammonium is bonded to the coordination complex, the compound must be an anion. If the coordination compound is an anion, then the TM has an -ate name.
