AI Technical Summary

Technical Problem

Existing connector manufacturing methods require multiple injection molds for each variant, leading to high tooling costs and long production times, especially for small production runs of connector variants with different contact element configurations.

Method used

A modular injection mold with interchangeable connector module pairs allows for the production of connector housings with varying contact element configurations using a single mold setup, reducing tooling costs and production times by enabling rapid changeovers and maintaining identical external geometries.

Benefits of technology

The modular injection mold enables cost-effective and efficient production of diverse connector housing variants with different contact element configurations, minimizing tooling costs and production times while maintaining high modularity and reliability.

Abstract

The invention relates to a modular injection moulding tool (100) for producing a plug connector housing (10) having a first and a second tool half (110, 120), which can be brought into a closed tool position relative to each other, the first tool half (110) having a first number of first mould insert spaces (111) each for receiving a first plug module mould (130; 131, 132, 133), the second tool half (120) having a second number of second mould insert spaces (121) each for receiving a second plug module mould (140; 141, 142, 143), wherein a first mould insert space (111) and a second mould insert space (121) lie opposite one another in the closed tool position and form a mould insert space pair, wherein a plurality of first plug module moulds (130; 131, 132, 133) and a plurality of associated second plug module moulds (140; 141, 142, 143) are provided, wherein a respective first and the associated second plug module mould (130; 131, 132, 133; 140; 141, 142, 143) form a plug module mould pair (170; 171, 172, 173), wherein a plug module mould pair (170; 171, 172, 173) can be inserted into each mould insert space pair, wherein, in the closed tool position (S2), a cavity (K) for receiving injection-moulding material is formed between the first plug module mould (130; 131, 132, 133) and the associated second plug module mould (140; 141, 142, 143) of a plug module mould pair (170; 171, 172, 173).
