Embodiment Construction

[0018] Referring to FIG. 1 , a hot runner mold 10 includes a fixed mold 12 and a movable mold 13 disposed to engage with the fixed mold 12 . The mold 10 is installed in an injection molding machine 14 to manufacture a resin molded product 18 .

[0019] The machine 14 comprises: a stand 16 ; an injection device 17 located on the stand 16 ; and a mold clamping mechanism 18 .

[0020] The mechanism 18 includes: a fixed pressing plate 21 , a connecting rod 22 mounted on the pressing plate 21 , and a movable pressing plate 23 slidably mounted on the connecting rod 22 . The movable platen 23 can slide along the direction shown by the arrow al, so that the movable mold 13 mounted on the platen 23 is moved to the closed position shown by the dashed-two dotted line. In this closed position, the mold 13 is clamped onto the stationary mold 12 by a predetermined pressure applied thereto. The movable platen 23 can also slide in the direction indicated by the arrow a2, thereby moving the ...

Abstract

A nozzle (26) for a hot runner mold (10) having a cavity (29) and a runner (27) formed in a body (24) thereof and communicating with the cavity. The nozzle leads to the runner and has a heating means (36), a heat-insulating groove (37), and a heat transmitting ring (38) provided on an outer peripheral surface (35) thereof. The nozzle has a f low passageway (33) formed therein. The heating means, the groove, and the ring are arranged in order along a direction of flow of resin (51) within the passageway. The groove serves to prevent heat generated by the heating means from being transferred to a distal end portion (43a) of the nozzle. The ring serves to release the heat of the distal end portion to the body. With this arrangement, the resulting molded product (11) can be removed from the mold without causing any stringiness between the runner and the distal end portion.

Description

technical field [0001] The present invention generally relates to a hot runner mold for manufacturing resin moldings, and more particularly, to an injection nozzle provided in the hot runner mold. Background technique [0002] FIG. 5 shows a conventional hot runner mold 101 with a nozzle body 102 disposed therein. The nozzle body 102 has flow channels 104 , 105 which are located centrally with respect to the transverse direction of the nozzle body and are formed extending longitudinally through them. These flow channels 104, 105 guide the molten resin 103 therethrough. The nozzle body 102 has a heating device 107 mounted around its outer peripheral surface 106 . This heating device 107 maintains the resin 103 at a predetermined temperature and prevents the resin 103 from curing within the flow channel 104 . [0003] However, with the runner mold 101 arranged in this way, when the molded product 108 is removed from the mold 101, it can cause stringiness in the molded produ...
