Embodiment Construction

[0034] Now refer to Figure 1 to Figure 3 , the temperature adjustment mechanism for an injection molding machine according to the first embodiment of the present invention will be described in detail.

[0035] Such as figure 1 As shown, a mold 1 for injection molding includes a fixed mold 2 and a movable mold 3 . The fixed mold 2 is installed on a fixed platen (not shown). The movable mold 3 is mounted on a movable platen (not shown) and is movable to be in contact with or separated from the fixed mold 2 .

[0036] The fixed mold 2 includes a fixed plate 4 , a sprue bush 5 and a positioning ring 6 . The fixed plate 4 is installed on the fixed platen. The sprue bushing 5 is embedded in the fixed plate 4 and is in contact with the movable mold 3 . The positioning ring 6 holds the sprue bushing 5 in the fixed plate 4 . The sprue bushing 5 has a recess 7 . The positioning ring 6 has a conduction hole 8 communicating with the recess 7 . The sprue 9 is provided at the deepe...

Abstract

A temperature adjustment mechanism used in an injection molding machine, which shortens the period of the moulding, and avoids the interwist in an optimum way. A channel (14) includes an open (14d), arranged on the outside surface near an exit (12) of an injecting nozzle (11) of the injection molding machine. A supply control unit (24) supplies at least one the cooling air and the heating air to the channel (14) for selectively injecting the cold loading medium, the heat loading medium and the mixture thereof to the outside surface neat the exit (12).

Description

technical field [0001] The invention relates to a temperature adjustment mechanism for adjusting the temperature of resin injected from an injection molding machine. Background technique [0002] A general injection molding machine performs a heating and melting process (heating and melting process) on a molding compound (resin sheet) inside a heating cylinder (injection nozzle) of the injection molding machine. The injection molding machine then injects the molten resin into the mold through a nozzle, and fills the mold with the resin (filling process). The injection molding machine then cools the resin filled into the mold, and removes the solidified resin from the mold (cooling process). One cycle of molding process (molding cycle) includes heating and melting process, filling process and cooling process. [0003] In the prior art, it is required to further shorten the molding cycle time to increase the yield of molded articles. However, the molding cycle time is not e...
