Project 1
Dear sir,
Here i have attahced my project 1 for your kind reference
Here I have mentioned the step followed while creating the assy:-
Steps for creating Core and cavity Surface
1) Scale - Need to add the shrinkage valuie ( to get perfect shape after the part gets solidified )
2) Draft - Need to check the angle draft ( fro the easly releasing of part)
3) Parting line - Need to create the parting line ( where the core and cavity meets each other)
4) Shut off surface - If there is any hole in the part for that area also we need to create the parting line for that shut off surface used (Once it finished then your core and cavity surface are formed)
5) Plain surface - need to create the plain surface (need to trim the surface inside the part area)
6) Copy surface - we need to copy the trim surface ( we are going to create both cavity and core )
7) Knit surface - By using one surface we need to join that suface and cavity surface. same as core surface also
After Spliting of core and cavity we are going to make core and cavity insert in assmbly file.
1) Create a assmbly file (browse the core bezele part file and insert it)
2)now create the another two part file (core and Cavity) Insert - new part
3)Now before staring the assemble drawing we need to make the orgin and the top view in correct possition
4)Assembly drawing orgin should match with the sprue location. for that make the assembly part file to float. right click- float
5) asembly- move component
6) select the component and make the option as make delta xyz and give the angle to rotate it. now the view will be corrected
7) now Orgin. make relation to plane part file plane to assembly plane) make sure the assembly orgin and the sprue location should be same
8) now fix the part Right click-fix
9) now open the core part file Right click - edit part file
10) now we need to create the core insert sketch the core insert and extrude
11) now we cant able to split the core insert because the the kint core sutrface is in ammbly file so for that we need to offset the kint core surface offset distance 0.00 because we need the core surface in that same position
12) Now use the curt with surface command and split the core insert
13) same as that we need to creat the cavity insert also
Steps for creating slider surface(Slider area profile is in cavity surface so we are going to work on cavity off)
1) First we need the chek the slider profile (wheather it is in core side are cavity side) In your file it is in cavity side so now we are going to work in cavity side
2) Now we need to open the cavity part file (we have to work on that for creating the slider area)
3) Need to make transperant in all the slide of the cavity block to see the slider profile clearly(right click in the surface and click transparent)
4) Now we need to create the plane by using the slider surface and sketch on it
5) Make the entire slider profile using the convert entries and exit the sketch
6) now use the split commant (Direct editing -split) Now select he sketch and select the plane now you select the slider profile alone and click ok
7) now u can see the two bodies in the solid bodies option (one is slider and another one is cavity off)
8) You cana see the hole in that slider profile for creating that sketch again in that same plane nad create the same profile slot by using convert entries
9) now extrude that profile (Upto next surface)
10)Now we have to make the perfect slider profile by using cut extrude nad boss exturde command ( as shown in the video)
11) now make a copy of the slider profile (because we add some extra profile in that silder so we need to cut that same profile in cavity surface)
12) For cutting that profile we are going to use subcrate ioption (Direct editing - combine)
13)Select the subract option and select the main body and select the copied slider
14) Now we get the entire slider profile in that cavity surface
15) now we need to fill surface (the extra cut made) while spliting the slider surface
16) use extrude boss option for adding material
17) need to do fillets in all hte sharp edges of the slider (same fillets have to make in cavity side also)
17) now used the same steps for creating that opposite side slider
18) now both the silders created . now save the slider in to seperate part file
19) now get into a main assy
20) create the new part file (slider)
21) And insert the slider in that position (Insert-features-import)
22)now we need to create the guide rail for slider area
22) Right click in core off and select the edit part
23) now make the guide raile profile and exturde it
24) Now we have to make a under cut in the cavity profile.(Guide rail profile)
25) Now we have make a screw to lock the guid rail
26) Create the new part and sketch on it now create the screw profile as shown in the video
27) now we have to make a thread hole in the core block. to mount the screw
28) Hole hazard option have to use to create the hole in the core bolck
29) now we have to create the stopper for the slider for that we have create the locking profile shown in the video and make cut extrude
30) now we to cut a semi circle profile in the slider edge surface (the think to note here is whle moould opening time the entire slider have to come out from the part area then only the part will release properly) for that we have to ensure the slider stopper position
Steps for creating Ejection Pins:-
1) Hide the cavity surface (we are going to work on ejection pins in core side)
2) sketch the area where ever you need a ejection pin in the part area (Mostely rib area need a ejection pin to avoid rib damage)
3) In mould tools select the core option to make the ejection pins
4) We need to make a relefe fo that ejection pins. throught out that area we dont need the guiding for ejection. (now we area using 6mm and 10mm pin so here we have give 20mm guiding form the top face of the part area
5) again sketch make a hole (dia6.95mmand 10.95mm) all the holes where we need a relefe
6) Extrude cut Make a off set option and slecte the direction give 15mmm and make extrude cut(Make sure that ejction pin is in hide conditon while making extrude cut)
we are not going to make sub inserts for this model
