2. Common design process in SWY
Slider cooling channel system in plastic mold
1. Angular pin (Gray color)
This pin has a draft angle from 10 deg ~25 deg. It will transfer vertical movement of cavity plate to horizontal movement of slide core. Angular pin usually fixes by cavity plate and slide locking block.
2. Locking block (Purpose color): locking block to make angular slider pin is shorter and increase the strength of angular pin.
3. Socket (Yellow color).
4. Flexible coolant hose (Gray color).
5. Plug (Yellow color.)
6. Slider insert core (Red color).
7. Pressure plug (Black color): it used to prevent cooling material out of the slider core.
8. Spring: when the angular pin and slide core separate, the spring force will push the slide core moving forward.
9. Cooling channel (Green color).
