Are you looking for advice on how to design a plastic mold or how to design a plastic part? No matter which it is, such general questions are going to get you pretty general answers. The more detail you can give us about what you are trying to do, the more helpful our answers will probably be.
Searching on the web sites of major plastics suppliers, like Sabic, Bayer, BASF, DuPont, Dow, and many others will likely turn up some good material.
Have a look at the DuPont website. They have a design guide for plastics that cover quite a variety of topics like: wall thickness in your part, rib design guides, boss design guides, etc. This will give you a good starting point when designing a plastic molded part.
