I was wondering how to creates gates for injection molding without using Solidworks Plastic.
A little more details? Can you use SW modeling?
Yes, I have Solidworks 2014, the basic model.
You can model the gates in SW 2014 can't you?
Well I've never had to do it before and all the research I did keeps say to do it in Solidworks Plastics.
Even if you had Solidworks Plastics, you would not be using it for modeling gates...Solidworks Plastics is a set of analysis tools. Just use the tools in Solidworks to model the gate. Now as far as which tools to use...that depends on a lot of things. But the bottom line is that a gate in a mold is nothing more than a cut of some sort. Whether it is a sub-gate, tab gate, fan gate, cashew gate / horn gate, lap gate, diaphram gate, or some other type of gate...it's nothing more than some type of cut (i.e., material removel). So your various tools for removing mateial (extruded cut, revolved cut, swept cut, lofted cut, cavity, or a combination of any of these) are the tools used to model the gate (as well as the runner).
A partner program like MoldWorks may help you with this. However, I think your best bet is to add the gate manually as Doug suggests. One thing I often do is create an envelope part that includes the runner and gate. Then I use it as a `subtraction tool' with the cavity feature to get the gate/runner geometry into the core and cavity inserts.
Here is a sample runner I use as an envolope to subtract from the cavity inserts and mold base.
It has the runners puller pins and gates all added to it.
The offset surfafe is the part I am gating into.
