Hallo
I pretty new to molding, and i need to get something molded.
The thing i want to get molded is this:
Imgur: The magic of the Internet
The fillets do not matter.
Does anybody have pictures of a mold that could do the job or maybe do something similar?
Best regards
Injection molding is very versatile. Essentially, a molder can make anything happen for enough money. The basic concept is that you want the main core and cavity halves to create as many of the features as possible. Any extra features such as side pulls that aren't in line with the travel direction of the core and cavity will require slides to be added to the mold ($$$$). This will actuate a pin to pull out of the side facing feature before the core and cavity separate.
I don't know if that makes sense but your part appears to be simple enough to require only one pull if you lay it on its side and have the core and cavity travel direction in line with the two smaller diameter holes.
I've had good luck submitting something like that to a 3D prototyping house and they will help you with part design for moldability. Two of the main things to focus on will be where you want the parting line of the core and cavity to be. Then from there, you will need to add draft to the faces of the part that are perpendicular to the parting line so that the part can be ejected from the mold.
If this doesn't fully make sense then I haven't had enough coffee yet but I hope that helps point you in the right direction.
Edit:
Another big consideration is overall thickness. You want the part to have as uniform of thickness as possible to eliminate sinking in the faces of thick cross-sections. You may have to core those out and add ribs to strengthen it back up. I'm not sure about the size of your part so that may not be necessary if it's very small.
