| Résumé : |
For the production of a container for a disinfectant gel precision mold maker Matrix developed a complex 6+6+6-fold 3-component mold. Two single parts are manufactured in one step and sealed in the tool by overmolding with a third component. The demanding mold design which uses two rotating index plates required a tailored hot runner solution which was supplied by Ewikon. |
| Note de contenu : |
- Two rotating index plates lead to the injection molding formula IMA + O
- Side gating of the low viscosity sealing
- 60° angled mold tips
- Drive axis passes through the hot runner system
45000 finished parts per day
- Fig. : Mold design for the in-mold assembly + overmolding concept (IMA + O). In the overlapping area of the rotating index plates - on the left above the lower cavity package, on the right below the upper one - is the assembly level
- Fig. 1 : The two single components are overmolded to te finished assembled component
- Fig. 2 : In order to reach the gating points in the very compact mold inserts, slim nozzle solutions were required
- Fig. 3 : Fully balanced flow channel layout in the manifold : 1) for gating the storage tank (main aggregate), 2) for gating the cover (vertical aggregate), 3) for overmolding with connection component (lateral aggregate)
- Fig. 4 : Cavity cluster in assembly position of the hot runner-side index plate with centrally positioned HPS III-MH nozzles for side gating
- Fig. 5 : Layout of the hot runner system : 1) Cover, needle valve nozzles HPS III-S3, melt channel diameter 3 mmm, special length 212 mm ; 2) assembly position, hot runner nozzles HPS III-MH, radial version with 2 tip inserts each ; 3) storage container, needle valve nozzles HPS III-S, melt channel diameter 4,5 mm |
