Embodiment Construction

[0030] The die-casting plant indicated at 10 in FIG. 1 is used for processing molten material, for example plastic melt. In addition to other (not shown) components such as an introduction device for the material to be processed, a mold cavity plate with mold elements and the like, the die-casting plant has a temperature-controlled distributor 20 and at least one The hot-runner nozzles 30 mounted on the distributor 20 , wherein each hot-runner nozzle 30 can be fixed on the distributor 20 with a stop element 40 .

[0031] The distributor 20 is formed by a distribution disc 21 having a substantially planar top surface 22 and a substantially planar bottom surface 23 parallel thereto. A plurality of flow channels 24 leading to outlets 26 in the bottom 23 of the distribution disk 21 are provided in the distribution disk 21 . Two through holes 27 are arranged symmetrically about the outlet 26 in the distribution plate 21, and a stepped groove 28 is provided for the through holes 27...

Abstract

The invention relates to an injection moulding device (10) comprising at least one distributor (20) and at least one injection mould nozzle (30) wherein each nozzle (30) is fixed to the distributor (20) by means of a holding element (40). In order to carry out a rapid mounting and ensure a long lasting sealing of all distributor nozzles, the holding element (40) is provided with at least one centring and / or fixing element (50) which is longitudinally displaceably arranged and is connectable to the distributor (20) in a final assembly position in such a way that the distributor (20) and the nozzle (30) are fixed to each other. The holding element (40) comprises at least one recess (41) for receiving the nozzle (30) and at least one other recess (42) for receiving the fixing element (50), which is longitudinally displaceably arranged therein. In the preferred embodiment, the fixing element (50) is embodied in the form of a fixing element for the holding device (40), in particular, a screw connection part (14).

Description

technical field [0001] The invention relates to an injection molding installation according to claim 1 . Background technique [0002] Die casting equipment is disclosed in a number of embodiments. They can be installed, for example, as a hot or cold channel system in order to guide the flowable plastic block to the separable tool block (mold) at a predetermined temperature and at a relatively high pressure. In addition, most temperature-controlled distribution systems are equipped with several (likewise temperature-controlled) nozzles, which guide the material to be processed through flow channels into the mold. [0003] As a rule, each nozzle has a flanged or stepped connection at its end facing the distributor, which attaches with a flat sealing surface to the flat end or side of the distributor (cf. DE-U1-201 00 840). The clamping force required for fixing the nozzle can be generated, for example, by means of a screw which is passed through a socket provided with a rou...
