콘테스트 개요

There is a casing which will be manufactured with injection molding. The casing already exsists in a draft version (see attached STEP file).
We are looking now for the perfect catch which is holding the two plastic parts together.

Requirements:
- Easy to assemble
- Hard to disassemble
- Strong connection between the two parts
- IMPORTANT manufacturing must be possible (mold release as marked in the attached screenshots) therefore the catch must be designes accordingly.
- Avoid holes or gaps between the two parts

Please make a proposal of a possible catch by adding the design to the existing STEP File. We are really looking or a high quality and stable working solution. We want to have a final version (CAD) of the catch not just concepts or ideas.

There is a chance of multiple winners for this contest if the quality of the work is good enough.

Thanks for your effort.

Failed to express the changes you would like the template to have. For this amount I would deliver the design of plastic injection molds together. Very simple piece.

one question for mold release , how does you release this slot core if they are not perpendicular with mold release : https://ibb.co/d7EHHG

Die Teile weisen einige Details auf, die sich negativ auf die Qualität der Bauteile auswirken werden.
Als Beispiel, Dome sollten niemals an der Wandung platziert werden, das führt zu Einfallstellen.
Weiterhin sind Bereiche im Unterteil in der 45° abgewinkelten seite nur durch Schrägschieber formbar.

Es wäre hilfreich die Bauteile im Kontext der gesamten Baugruppe bewerten zu können.

Gerne können Sie mich hierzu kontaktieren.

  Nach weiterer Begutachtung komme ich zum Schluss das hier ein komplettes Neudesign erforderlich ist. Fast alle Grundregeln der Konstruktion von Spritzgussteilen hinsichtlich Formbarkeit und Kostenoptierung wurden hier vernachlässigt. (Hinterschneidungen, dicke Bereiche, sehr lange Dome- >3xØ..)
  
  Aus meiner Sicht und jahrelanger Spritzguss-Erfahrung sind die Teile nicht herstellbar.
  
  Hier tipps zum Design:
