Embodiment Construction

[0027] figure 1The hot runner distributor, generally designated by the reference numeral 10 , is part of an injection molding plant for producing molded parts from a flowable mass, for example a plastic melt. In the hot runner distributor 10, the fluid channel 12 is composed of a main fluid channel 12a and a secondary fluid channel 12b turning from the main fluid channel 12a. The fluid main channel 12 a and the fluid secondary channel 12 b are formed, for example, as bores in the hot runner distributor 10 . In order to divert the melt entering into the secondary fluid channel 12b and flowing through the main channel 12a in the downward direction, a plug 18 is inserted into a gap intersecting the secondary fluid channel 12a, which is formed as a through hole and is substantially vertical It extends in the extending direction of the main fluid channel 12a. The plug 18 now comprises a rotationally symmetrical sleeve 20, in which a channel 22 extending radially inwards from the ...

Abstract

The invention relates to an arrangement for the sealing and / or connecting and / or diverting of channel sections in a hot or cold runner (10), which has at least one flow channel (12) which can be fed with plastified melt, where this channel can be sealed so as to be permeable to fluid by a plug (18) fastened to the runner system and / or is divertible and / or connectable to a further flow channel. In order to provide an improved arrangement for the sealing of channel sections (12a) in a hot or cold runner, each plug on the runner system can be secured in a recess which extends in essence perpendicularly with respect to the channel section to be sealed and which intersects the same. Each plug also has at least one peripheral area (24) which, in the operating state, is in contact with a recess area opposite to said peripheral area, in a manner that prevents permeation of fluid.

Description

technical field [0001] The invention relates to a system for closing and / or connecting and / or diverting runner sections in a hot or cold runner distributor having at least A fluid channel that can be filled with plasticized material can be closed in a fluid-tight manner and / or diverted and / or can be connected to a further fluid channel via a plug attached to the distributor. Background technique [0002] In installations for hot-channel injection molding, it is known to insert cylindrical plugs in the corner region of the distributor channel, which close the ends of the channel and / or are pressure-tightly connected at an angle as deflectors. Runner section that turns. For example, according to EP-A-0 226 798, the filler piece is placed coaxially on the end of the main channel, in order to connect the deflection piece in each case by means of a conical bore. This conical bore is continued in the plug by means of a curved bore which forms the outlet opening of the distributo...
