DESCRIPTION OF THE EMBODIMENTS

[0030] Reference will now be made in detail to certain embodiments, examples of which are illustrated in the accompanying drawings, in which some, but not all features are shown. Indeed, embodiments disclosed herein may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Whenever possible, like reference numbers will be used to refer to like components or parts.

[0031] FIG. 1 shows a first variation of the injection mold 1 according to the disclosure. FIG. 2 shows a first mold half 2 of the injection mold 1 in a partially exploded view and FIG. 3 shows a magnified view of detail A of FIG. 2. FIG. 4 shows the same first mold half of the first variation of FIGS. 2 and 3 in a partially exploded view form a different viewing angle. FIG. 5 shows a cavity block 7 of the first variation in a partially sectioned view. The injection mold 1 shown in the drawings comprises a first mold half 2 and a second mold half 3 which are during operation displaceable with respect to each other in a first direction x between an open position and a closed position. During operation, the first mold half 2 and the second mold half 3 are usually arranged in an injection molding machine (not shown).

[0032] In FIG. 1, the second mold half 3 is shown spaced apart and pivoted away (indicated by dashed lines) from the first mold half 2 to enable a better view of the first and the second mold halves 2, 3. The first mold half 2 comprises a cavity plate 4 with a front face 5 with a recess 6 in which at least one cavity block 7 is arranged. In the shown variation the recess 6, best visible in FIG. 4, accommodates eight cavity blocks 7 arranged adjacent to each other in a grid-like manner forming two rows and four columns. As shown, per cavity block 7 at least one cable 11 interconnects the cavity block 7 in a mounted position with a connection box 12, as shown in FIGS. 1 to 3. The cables 11 in the shown variation are electrical cables for supplying heating elements and connecting sensors. However, the same cable 11 or a different cable may comprise other types of connection means such as one or several tubes for conducting fluid, preferably cooling fluid and/or fluid to detect leakage and/or one or several optical fibers for data exchange. Alternatively, or in addition, the same or a different cable can be connected to the same connection box 12 and/or a different connection box. In the shown variation, the cables 11 are arranged in a same or different cable conduits 13 extending at least partially in the first mold half 2. If appropriate, as visible in FIG. 1 the cable conduit 13 may at least partially be covered by a cover 24. As illustrated in FIGS. 3 and 4 the cable conduit 13 extends at least partially in the front face 5 of the cavity plate 4 and is formed as a notch extending at least partially along an edge of the recess 6 adjacent to the front face 5. The cable conduit 13 essentially surrounds the recess 6 and the cavity blocks 7 therein. In a transition region, the cable conduit 13 passes through the cavity plate 4 to a side face 15 of the first mold half 2 where the connection box 12 is arranged to which it is interconnected. As best visible in FIG. 4 the cable 11 ends in a first connector part 21 formed as a plug by which it is interconnected to a respective second connector part 22 of the connection box formed as a socket. By this the connection between the cavity block 7 and the connection box 12 is effortlessly possible. In the shown variation, each cavity block 7 comprises at least one first cavity half 8, as shown in FIG. 5, forming in a closed position of the injection mold 1 with a corresponding second cavity half 9 arranged at the second mold half 3, as shown in FIG. 1, a cavity suitable to receive plasticized plastic material to form a part therein. On advantage is that the cavity blocks 7 are independently from each other removable from the first mold half 2 by loosening the bolts 23 holding the cavity block 7 in place. Once the bolts 23 are removed the cavity block 7 can be pulled out of the recess 6 in the first direction x, as best visible in FIG. 3. The cavity blocks 7 have in the first variation a rectangular cross-section. As can be seen in FIG. 5 the cavity block 7 has a bottom face, which faces when inserted into the recess 6 the back face of the recess 6. In the bottom face 25 of the cavity block 7 inlets and outlets are arranged, which connect to corresponding inlet and outlets of the respective cooling channel 18 in the back face 17 in the recess 6. FIG. 5 further shows a cable channel 28 extending between a center opening 27 of the cavity block 7 to a side face 26 of the cavity block 7. The cable channel 28 is formed as a groove in the bottom face 25 of the cavity block 7. FIG. 4 shows a multipart construction of the cavity plate, which comprises a first layer 19 and a second layer 20. The first layer 19 and the second layer 20 arranged in a stacked manner in the first direction x. The first layer 19 is in the shown variation formed as a circumferential frame which encompasses the cavity blocks 7. The second layer 20 forms the back face 17 of the recess 6 and comprises cooling channels 18 connected in the assembled state of the injection mold 1 to the cavity blocks 7 respectively. As shown in FIG. 3 the cavity block 7 of the shown variation, may comprises alignment means 29 arranged at the side face 26 of the cavity block 7 engaging during insertion and/or during operation with the back face 17 of the recess 6. The alignment means 29 can be flat-sided sliders and grooves arranged at the side face 26 of the cavity block 7. As illustrated in FIGS. 3 and 4, the side wall 32 of the recess 6 comprises here a U-shaped indentation 30 extending in the first direction x and forming part of the cable conduit 13 for routing the cable 11 along a side face 26 of the cavity block. The two edge regions of the indentation support the cavity block 7 perpendicular to the first direction. For preventing undesired forces on the cable 11 inside the cavity block 7 a cable clamping means 31 is attached to the side face 26 of the cavity block 7. In the assembled state the clamping means 31 is accommodated in the indentation 30 of the side wall 32 of the recess 6.
