Description

Technical Field

[0001] The present invention relates to a manifold for a hot runner injection mold, and in particular to a modular manifold formed by dividing the manifold into a plurality of manifold modules, which are then interconnected. Background Art

[0002] A plastic injection mold device equipped with a hot runner system generally has the following structure. Specifically, as disclosed in Patent Document 1, the injection mold device comprises an upper mold block and a lower mold block that are separably coupled to each other, a pair of mold blocks forming a cavity therebetween, and an insertion hole formed in one of the pair of mold blocks (preferably the movable mold block). The device comprises at least one nozzle having a front end portion of an internal passage in a central direction open to the cavity. The device also comprises a main nozzle connected to the nozzle portion of an injection molding machine on one side and a top end of the at least one nozzle coupled to the other side. Molten resin supplied through the main nozzle is heated by a heat transfer heater while a manifold is formed within the device to provide a molten resin passage for the internal passage of the at least one nozzle.

[0003] In the conventional injection mold system described above, the manifold consists of a single manifold module. The heat transfer heaters installed on the manifold module to heat the molten resin passing through the molten resin channel cannot evenly heat the entire manifold module, resulting in thermal deviations across the entire manifold. This thermal deformation of the manifold can cause various problems. For example, thermal deformation of the manifold can create gaps where it meets the nozzle, leading to leakage of molten resin through these gaps. This can also prevent the nozzle from accurately meeting other components, leading to reduced precision and accuracy.

[0004] Furthermore, in conventional injection mold systems, the manifold module is composed of a single plate that is sufficiently large to cover the entire mold cavity. This results in a heavy overall weight and cumbersome operation. Furthermore, in order to minimize overall thermal deviation, the entire manifold must be heated, resulting in high heat consumption.

[0030] The connecting pipe module (500) is provided with a connecting channel in the direction of the central axis, and a heat transfer heater is provided on the outer wall. The outlet (203) of the inlet side manifold module (200) and the outlet of the nozzle side manifold module (300) are connected by the nozzle side manifold module (300) on one side. Specifically, one end of the connecting pipe (503) is connected to the outlet (203) of the inlet side manifold module (200), and the other end is connected to the first connecting portion (410) or the second connecting portion (420) of the coupling device (400).

[0033] The first connecting portion (410) is connected at one end to one side of the inlet (202) of the second resin channel (304) of the nozzle side manifold module (300), and is provided with a first hemispherical joint portion (411) protruding outward on the outer circumferential surface of the other end.

[0034] The second connection portion (420) is a second connection portion (420) having a front end facing the first contact surface (413) of the first connection portion (410) in a coaxial direction and provided with a second contact surface (423) in contact with the first contact surface (413), a second hemispherical joint portion (421) protruding outwardly provided on the outer circumferential surface, a second inner connection portion (424) having a second inner resin channel (422) communicating with the first inner resin channel (412) in a coaxial direction in the direction of the central axis, a second outer connection portion having a hemispherical shape and a concave groove (425) slidably accommodated in the outwardly protruding second hemispherical joint portion (421) of the second inner connection portion (424) on the inner side surface of one end, and a joint portion (426) connected to the outlet (203) side of the first resin channel (304) of the inlet-side manifold module (200) at the other end. In the direction of the central axis, there is a third internal resin channel (427) that connects the second internal resin channel (422) with the outlet (203) of the inlet-side diverter plate module (200). The second hemispherical joint (421) will not be separated from the second inner connecting portion (424). The fixing screw (442) for fixing is located on the second hemispherical joint (421) and passes through the through hole (441) provided and is fixed to the fixing screw (442). Therefore, the part of the fixing screw (442) protruding from the through hole (441) will be stuck in the through hole (441), so that the second hemispherical joint (421) will not be separated from the second outer connecting portion (428).

[0035] A sealing ring (429) for preventing resin leakage is installed on the inner wall surface of the hemispherical groove portion (425) of the second outer connecting portion (428) that wraps the above-mentioned second inner connecting portion (424).

[0036] The fixing device (460) comprises a first sliding support ring portion (431) slidably coupled to the first hemispherical coupling portion (411) of the first connecting portion (410), and a second sliding support ring portion (432) slidably supporting the second hemispherical coupling portion (411) of the second connecting portion (420), and includes a retainer ring component (440) that detachably fixes the first sliding support ring portion (431) and the second sliding support ring portion (432). A heat expansion absorbing ring (450) is coaxially provided on the second connecting part (420) at the rear front end thereof so as to accommodate the heat expansion of the second connecting part (420) in the longitudinal direction. The heat expansion absorbing ring (450) is provided with a through resin channel (451) connected to the first resin channel (204), and has a deformation accommodating groove (452) formed along the circumferential direction on the outer wall. When the second connecting part (420) expands in the longitudinal direction due to the heat of the heat transfer heater, the heat expansion absorbing ring (450) is squeezed by the joint (426) of the second connecting part (420) that has become longer due to the expansion, thereby being compressed. At this time, the deformation accommodating groove (452) of the heat expansion absorbing ring (450) contracts to accommodate the compression of the heat expansion absorbing ring (450).
