It is a part for JL handbrake project. The tool is 4 cavities with long sliders travel, and the part only has small draft because of assembly request limited, so considering the risk of part sticking to the slider, we design sliders as double demoulding action with cylinder and spring. Also in order that the tool can run automatically completely, the slider insert have TEFLON coating made for help demoulding, and then the tool was delivered on time after run 400 shots full automatic production.
It is a part for JL handbrake project. Since the part surfaces are critical and visual, so at the early of design stage, in order that the part will not be scratched during demoulding, we discussed many solutions with customer, firstly we designed the tool with putting the parts horizontally, and then designed it with 12 sliders because putting the parts vertically. At the same time, in order to getting a good cooling, part surface and making better polishing and graining between two sliders, the slider size have been increasing, and the required injection machines also become from 160TON to 450 Ton, at last we got perfect PL mismatch and visual surface.
It takes 1.5 months from DFM to final tool design approval, and also only 1.5 months for manufacture stage.
Key Point 1：The parting surfaces with large drop. Solution: We designed the core and cavity block with solid locker to help position. To avoid core and cavity block moving cause flash & mismatch issues during injection, we designed wear plates at shut off area between the core&cavity and A&B plate to against the pressure from injection.
Key Point 2: The product have high request for the strengthen of the end filling area. Solution: Designed clod slug well at the end of filling area. In this case, the end filling area will have hot melt resin for welding. Then, the end area can have good mechanical strength performance.
