- a plurality of webs 8, 9 are arranged behind one another along a perpendicular to the longitudinal axis L and perpendicular to the first transverse axis Qi extending second transverse axis Q 2 , the webs 8, 9 are divided into two groups of webs 8, 9, wherein the webs passing one of the groups parallel to one another and the webs 9 of the other groups 7 parallel to each other, wherein the bars 8, 9 of the groups 6, 7 intersect, namely along crossing axes 5a, 5b, which extend parallel to the second transverse axis Q 2 as well as the longitudinal extent of openings 12, which are bounded by the webs 8, 9.
- first sub-mixing element 15a of the pair 16 in the direction of the second transverse axis Q 2 has no adjacent pairs of intersecting webs, just as the second sub-mixing element 14b in the direction of the first transverse axis Qi.
- Fig. 4 also shows that in each case two rotated by 90 ° arranged sub-mixing elements 14a, 14b; 14b, 14c; 14c, 14d ... two different, rotated by 90 ° to each other and in the concrete embodiment, both the longitudinal axis L (here the longitudinal center axis) receiving separating planes Ti, T 2 limit, where the respective sub-mixing elements of a sub-mixer insert 2 come to rest on the perpendicular to the longitudinal axis L adjacent or opposite sub-mixing elements of another sub-mixer insert second
- a separation plane Ti is drawn, which receives the longitudinal axis L of the mixer insert 1 in the mounted state.
- This parting plane Ti meet in the drawing plane bottom right outermost or end-side sub-mixing elements of the adjacent sub-mixer inserts 2a, 2b.
- the subsequent part along the longitudinal axis L mixing elements meet at a here to the separating plane arranged at right angles Ti parting plane T 2, which is also penetrated by the longitudinal axis L.
- the first transverse axis Qi is perpendicular to the surface extension of the first parting plane Ti.
- the second transverse axis Q 2 is perpendicular to the surface extension of the second parting plane T 2 .
- the first parting planes Ti are framed between two mutually parallel and perpendicular to the first parting plane Ti extending radial planes R- ⁇ , which are bounded by two opposite end faces of two sub-mixing elements.
- the second parting planes T 2 are arranged axially between two radial planes R-1 defined by two partial mixing elements.
- the radial planes R-1 extend with respect to their surface extent both perpendicular to the first and to the second parting planes Ti and T 2 and are orthogonally interspersed by the longitudinal axis L.
- FIG. 6 Evident is a section of a sub-mixer insert 2 comprising two rotated by 90 ° to each other arranged sub-mixing elements 14a, 14b, which are formed and arranged as described above.
- an injection molding tool 18 having several moldings for producing the partial mixer insert 2 in the plastic injection molding process.
