    • The present invention is directed to an injection molding valve configured to prevent the leaking or stringing of injected thermoplastic from the valve. The valve includes a housing having a first bore along a length thereof and a second bore intersecting the first bore. A rotatable member is inserted through the second bore and is in communication with a lever for the actuation thereof. The rotatable member includes a hole therethrough such that when the hole is aligned with the first bore, thermoplastic may travel freely through the first bore. The second bore further includes at least one groove in communication with a port for receiving injected thermoplastic. The injected thermoplastic is hardened to form an seal therein and configured to prevent thermoplastic from leaking out of the valve housing.
    • 本发明涉及一种注射成型阀,其被配置为防止从所述阀引起的注射的热塑性物质的泄漏或引线。 阀包括具有沿其长度的第一孔和与第一孔相交的第二孔的壳体。 可旋转构件插入穿过第二孔并且与用于其致动的杆连通。 可旋转构件包括穿过其中的孔,使得当孔与第一孔对准时,热塑性材料可以自由地穿过第一孔。 第二孔还包括与用于接收注射的热塑性塑料的端口连通的至少一个凹槽。 注射的热塑性塑料被硬化以在其中形成密封并且构造成防止热塑性体从阀壳体泄漏出来。
