Embodiment Construction

[0025] see figure 1 , shows a partial view of an exemplary side-gated or edge-gated hot runner injection molding apparatus according to an exemplary embodiment of the present invention. The arrangement comprises a manifold 1 located within a first platen 2 , and a plurality of hot runner nozzles 30 for supplying melt to at least two separate mold cavities 15 . exist figure 1 , only one side-gate hot runner is shown.

[0026] Each hot runner nozzle 30 includes a nozzle body 4 adapted to the manifold 1 in one axial direction of the nozzle body 4 to allow the melt material to flow from the outlet melt channel 22 into the first melt channel 32 , the first melt channel 32 is arranged along the first axis 33 inside the nozzle body 4 of the hot runner nozzle 30 . In the opposite axial direction, the nozzle body 4 penetrates the first formwork 2 and is supported on the second formwork 3 by its flange.

[0027] Each hot runner nozzle 30 further includes a separate and removable noz...

Abstract

A hot runner injection modling device comprises an injection molding manifold including an inlet melt path and a plurality of outlet melt paths and a plurality of hot runner nozzles connected to the outlet melt paths. Each of the hot runner nozzles comprises a nozzle body defining a first nozzle body melt path with a first axis. A tail shell of each of the nozzles is connected to the corresponding nozzle body and comprises at least two auxiliary melt path parts each provided with a second axis. An angle is formed between each second axis and the first axis. At least two nozzle tail ends are disposed at nozzle tail end shells. A nozzle tail end heater is disposed largely along the direction of a first melt path in each nozzle tail end zone.

Description

technical field [0001] The invention relates to a hot runner injection molding device. More particularly, the present invention relates to side-gated or edge-gated hot runner nozzles. Background technique [0002] Side-gated or edge-gated hot runner nozzles are known. Existing concepts have drawbacks due to uneven distribution of heat between the device and the melt. [0003] Proper heat distribution is important to the good operation of hot runner injection molding equipment. It is important that all functional units of the device have the necessary temperature before production, since the design of the components is made according to the operating temperature of the device. For example, the nozzle tip will seal with the gate hole only after heating of the nozzle body and corresponding thermal expansion. Accordingly, if the nozzle is not heated to the required temperature, a leak will occur. [0004] Furthermore, even the same part will have areas that require more hea...
