Week 12 Challenge

Dear Sir,

Here I have attached the week 12 challange for your kind reference, Here I have the entire ejection assy and sprue bush and cooling channels

Steps for creating the Ejection Pins:-

1. we have already the ejection holes for in the core insert area. noe we have to create the ejection pins in that hole
2. Before making the ejection pins we have to make a relief hole for that ejection pin from the top upto 20 mmmonlu ejection pin guiding needs after that we have to create the relief hole
3. now we have create the ejection pins
4. In that pin collar have to in D shape (because the ejection pins are profiles pins to avoid the cavity damage )
5. once we create all the ejction pins then we have to create the ejection plate and ejection back plate
6. for both the ejeciton and the ejection back plate we can use the same dimension used the insert area
7. once we finish the ejection assy we have to create the spacer block for the ejctioon system (the ejection we travell in that spacer area only
8. After that we have to create the bottom plate

Steps for creatign Sprue and runner and gate:-

1. First we have to create the top plate for that model in cavity area
2. then we have to make a hole of 120 dia to 10mm depth for fixing the locating ring
3. now we are going to make a sprue bush (The material will travell in that pathway and reaches the part area
4. first make a 5mm dia hole and make a extrude hole till the cavity plate (there should a draft of 1.5 degree
5. now the sprue is completed
6. now we have work in core side (the runner will in corre side only)
7. make the path way for the runner area (keep some distance for themake gate)
8. the dia is 4mm the depth of 4mm
9. the now we have to make a gate (for this we are going to use edge gate)
10. To provide that we have to make a sketch aas shown in the video
11. Once we finish the entire runner and the gate (now we have to subcract the runner area in the main core insert)
12. the runner and the gate will be completed

Steps for creating the air-vent:-

1. near the part area we have create the path way (the air should escape while closing the mould)
2. this will leads to a part defect (short Fill, Burn mark, Bluster, etc)
3. the air-vent will be in the depth of 0.5mm
4. and the air-vent which touches the part area will be in the depth of 0.05mm
5. If we increase the depth means it will leads to a flash (excess material in the part)

Steps for creating the Cooling channels:-

1. For this model we are going to use square type cooling channel
2. for this we have to use hole wizard command and have to make a hole as shown in the video
