Project 2

CORE AND CAVITY BLOCKS

• firstly i am import the .xt file of knob into my solidworks software
• and then seprately save the solid partfile and then click on draft anallysis and check wether any adequate drafts are applied to the body or not
• afterthat, click on scale commond and and give the value as 1.006, and make it bigger
• then, click on parting lines commond and select the parting line for knob
• know go to shutoff surfaces and select the required hollow sides to close those and make as fully closed knob
• then using lofted surface commond to cover the nofill shutoff surfaces in shutoff surfaces base
• after successfully complete the thing went to top plane and create a reference plane and name it as tooling direction. which is some 40 to 50mm down to the main top plane and draw two perpendicular line for reference to made surfaces
• then go to lower face of componenet and get it into sketcher and draw similar lines and split the body using split commond in mold page
• using ruled surface commond and make sweep as ticked and took tooling direction plane as reference and create the surfaces.
• after creating all surfaces using knit surface commond combine all the surfaces and merge all as one
• made a copy of parting surface and merge the two with two bodies(core,cavity)
• after that get the prepared body into new assembly file and save it as

EJECTOR PINS AND EJECTOR PLATES

• In the creation of ejector plates and ejector pins get the core block into sketching mode and draw the reqired sketch on it, and using extrude cut commond to create ejector pins. and made the D heads for all ejector pins
• And then get the one of the ejector head into sketcher mode and draw the rectangles of total core block length and extrde it to create to ejector plates.

RUNNERS AND GATINGSYSTEM

• In order to create runner get the cavity block into sketcher mode and darw the powring basin and sprue and convert the sketch into solid by exrude bossbase commond from features
• Now exit from sketchermode and get the core block into sketch. and draw the runner and gating sketchs w.r.t their dimensions and create them using extrude boss base

VENTS AND COOLING CHANNELS

• In order to create the vents in body, get the core into sketch mode and draw the required shape for vents and create it into feature by extrude commmond
• Then remove it by combine commond in direct editing face. to get the print of vent on core block

Finally to create the cooling channels by hole wizard commond in required places
