While not an exact duplicate, you might benefit from some advice given in this related question. I will repeat some of that advice here.
While the breakdown of your presentation time for each topic is important, a more important thing is to see your presentation as a unity, and use each part of it to demonstrate your abilities in all aspects of your academic work. Ideally, your presentation of your research should show what a great teacher you are (e.g., by exhibiting your engaging style, the ease of explaining the material, etc.) and your presentation of your teaching style and method should show what a serious and thorough researcher you are (e.g., that your method is informed by pedagogical research, etc.). Similarly, your professional service is likely to interact with your research and/or teaching, so it can often be weaved into these parts to augment them as you go. By augmenting topics in this way, you can "cheat" the time allowance --- e.g., your audience is seeing what a good teacher you are both when you talk about teaching and when you talk about research or service.
Likewise, rather than trying to demarcate your research philosophy from your actual research, and do these in a strict sequential order, it ought to be possible to weave these together so that they are a unity --- e.g., discuss your research philosophy, but use examples of your past research to concretise this discussion. Similarly, use discussion of your research philosophy to explain choices you've made within your actual research. As you illustrate your past research, you can raise questions that you want to pursue in future research, again tying this in so that your past and future research are unified.
The ideal result here is for each part of your presentation to augment the other so that the exact split of time between the parts is not to the derogation of one or the other. If you can make an engaging presentation where your research, teaching and service weave together into a compelling whole then your audience is likely to be left with a positive impression of each. It is unlikely that people will care much about the time split so long as they felt that your presentation was engaging and interesting, and they got at least a little taste of each part and how it ties together as a whole.
