Embodiment Construction

[0030]

[0031] First, before describing the characteristic configuration of the injection molding apparatus of the present embodiment, the general configuration of the injection molding apparatus of the present embodiment will be described with reference to the drawings.

[0032] like figure 1 As shown, the injection molding apparatus 1 of this embodiment has the heating injection apparatus 2 and the mold clamping apparatus 3 provided so that the heating injection apparatus 2 may be opposed. The heating injection device 2 and the mold clamping device 3 are installed on a base frame (not shown).

[0033] (heated injection device)

[0034] The heated injection device 2 includes an injection cylinder 21 . A funnel 22 is attached to the upper part of the injection cylinder 21, and the funnel 22 is used for supplying the pelletized thermoplastic resin into the injection cylinder 21, and this thermoplastic resin becomes a raw material of a molded article. Around the injection ...

Abstract

When injection molding using an electrically conductive material, the present invention limits the lengthening of injection molding cycles and the occurrence of molded product appearance defects and imparts uniform electric conductivity to the molded product. An injection molding apparatus is provided with a heating and injection means for heating and melting an electrically conductive material toa flowable temperature and injecting same into a molding mold. In said molding mold, at least a portion of forming surface of the cavity has multiple electrically conductive sections that are insulated from each other and a prescribed voltage is applied between the electrically conductive sections. A static mixer is provided in the region from the tip of the heating and injection means to the flow channel for the electrically conductive material.

Description

technical field [0001] The present invention relates to an injection molding apparatus and an injection molding method, and in particular, the present invention relates to an injection molding apparatus and an injection molding method for performing injection molding using a conductive material. Background technique [0002] Heretofore, a method of injection molding a molded product using an injection molding apparatus has been known. Specifically, the method includes a step of heating the resin material to a flowable temperature using an injection molding apparatus to melt the resin material, a step of filling the cavity of the pre-clamped mold with the molten resin material, and melting the filled resin material. It consists of the steps of maintaining pressure and cooling of the resin material, and the step of opening the mold and taking out the molded product. [0003] Examples of molded articles that are injection-molded by an injection molding apparatus include automo...
