- complex injection molds are used, which often have over two relatively adjustable tool parts addition also slide in order to produce the necessary complex shapes of the housing can
- mold parting plane In the contact area of the two tool parts is the so-called mold parting plane. This unavoidably poses the problem that form irregularities such as bumps, sharp edges, over-tipping or other irregularities on the injection molded part.
- the object of the invention is to provide a housing shell made of an injection-molded plastic or a housing made of an injection-molded plastic for a buckle or a method for producing a housing shell, which has a higher quality appearance with low production costs.
- a housing shell for a buckle with at least one side wall having an outwardly facing side surface on which a groove is provided which extends perpendicular to the longitudinal direction of the housing shell completely over the side surface.
- the basic idea of the invention is that a deliberate interruption of the outer surface is provided on the housing, wherein this interruption is arranged so that the parting plane between two tool parts (or a tool part and a slide) is arranged therein and a possible spray burr is "laminated" therein ,
- the injection molding tool provided for the production of the housing shell accordingly comprises a slide element which has a partial cavity of the entire injection molding tool, wherein the partial cavity in the slide element extends to a point at which the groove is formed on the side surface.
- the side wall has a tapering section in the transition region from the side surface to an upper side, on which at least part of a receiving opening for a tongue is formed.
- the tapered portion of the side wall is manufacturing technology important because the housing shell made in the injection molding tool can be removed from the injection mold so easier.
- the tapered portion is preferably formed on the sidewall between the groove and the top.
- the side wall has a curved outer contour.
- the curvature is in particular designed so that the housing shell produced can also be easily removed from the stationary tool part of the injection molding tool.
- the groove is formed in a region of the side wall having the largest width of the side surface. This will remove the produced housing shell, as these smoothly from the respective tool part . can be removed from the mold, since the widest point of the housing shell is in the region of the mold parting plane of the injection molding tool.
- the housing shell is made of a plastic.
- Plastic is the least expensive and easiest to process material in an injection molding process.
- a housing for a buckle with a housing shell of the aforementioned type.
- the housing thus produced can thus be formed from a housing shell or from a plurality of housing shells. Further, further shell elements may be provided which cooperate with the housing shell to provide a sealed housing.
- the housing shell has four side walls.
- the housing can thus be formed from only a single housing shell.
- the housing is then made in one piece, wherein the housing is injected around the internal mechanism of a buckle.
- a further embodiment of the invention provides that the housing shell cooperates with a further shell element, wherein a groove is formed in the transition region.
- the housing shell and the shell element can be made separately from each other, wherein then the internal mechanism of the buckle is inserted into the housing shell, which is then closed by the shell element.
- a clip or pin connection is provided for this purpose.
- the groove in the transition region can in particular be aligned with the groove formed on the housing shell, so that the overall result is a uniform appearance of the housing.
- the housing has four sides around which the groove extends continuously. Regardless of the number of housing shells and shell elements used in the housing, the housing has a continuous groove around all sides. The junction of the housing shells and the shell elements and the mold parting plane of the housing shells produced can all lie in the region of the groove.

- the side walls 12, 14, 16 each have side surfaces 22, 24, 26, it being apparent from FIG. 1 that a groove 28a is formed on the first side surface 22.
- the groove 28a extends continuously over the entire first side surface 22, wherein the groove 28a extends perpendicular to the longitudinal direction L of the housing shell 10.
- the side walls 14, 16 are curved so as to provide a first side surface 22 of varying width, with the groove 28a disposed in an area having the greatest width.
- the housing shell 10 of Figure 1 is shown in a side view, wherein the second side wall 14 together with the second side surface 24 shown is.
- the housing shell 10 of Figure 1 is thus shown in Figure 2 rotated by 90 °.
- the second side surface 24 also has a groove 28b which extends perpendicular to the longitudinal direction L of the housing shell 10 and completely over the second side surface 24.
- the groove 28b is arranged at the same height as the groove 28a and merges in the transition region of the first side surface 22 to the second side surface 24 in the groove 28a, so that a continuous groove 28 is formed on the housing shell 10.
- the first side wall 12 is also curved, as can be seen from FIG. 2, so that a second side surface 24 with a varying width results.
- the groove 28b is arranged analogously to the groove 28a at the widest point of the second side surface 24.
- FIG. 2 shows that the housing shell 10 is not completely closed. Above the groove 28, the housing shell 10 has a completely encircling cover element 29, on which the upper side 20 is formed.
- the cover element 29 is designed such that it has an upper side 20 opposite end, which merges on the side surfaces 22, 24, 26 in the groove 28 or closes at the level of the groove 28.
- the housing shell 10 also has a mounting pin 30 which extends from the end of the cover member 29 and is used to attach a shell member, not shown here, to provide a closed housing. The junction between the housing shell 10 and the shell element is then at the height of the groove 28th
