摘要： A collar for a hot runner nozzle of an injection molding apparatus includes a generally cylindrical body having a first flange extending inwardly from a first end thereof. The first flange is provided to abut a nozzle head and at least a portion of a nozzle body of a nozzle. An alignment flange projects from an inner wall of the generally cylindrical body and is spaced from the first flange. The alignment flange contacts the nozzle body to restrict tipping of the collar relative to the nozzle during assembly of the injection molding apparatus.

摘要： A nozzle system is provided for an injection molding machine. The nozzle system includes a nozzle tip that is removably connected to a nozzle body with a sealing and mounting sleeve element. The nozzle body includes a first connector for releasably connecting with a second connector defined on the sleeve. The sleeve element further includes an alignment bearing for engaging a bearing surface defined on the nozzle body for precisely locating the nozzle tip within the nozzle body along on a predetermined axis. Further embodiments of the invention provide a valve pin disposed in the nozzle body and nozzle tip. The valve pin includes a bearing surface for engaging a guiding surface defined on the second melt channel for aligning the end of the valve pin with a mold gate. Further embodiments also provide an integrally connected nozzle tip and sleeve element.
摘要翻译：为注射成型机提供喷嘴系统。喷嘴系统包括一个喷嘴头，该喷嘴头可拆卸地连接到具有密封和安装套筒元件的喷嘴体上。喷嘴主体包括第一连接器，用于与限定在套筒上的第二连接器可释放地连接。套筒元件还包括对准轴承，用于接合限定在喷嘴主体上的支承表面，用于沿着预定轴线精确地将喷嘴头定位在喷嘴体内。本发明的另外的实施例提供一种设置在喷嘴体和喷嘴尖端中的阀销。阀销包括用于接合限定在第二熔体通道上的引导表面的轴承表面，用于将阀销的端部与模具浇口对准。另外的实施例还提供了一体地连接的喷嘴尖端和套筒元件。

摘要： An injection molding torpedo which can itself be injection molded by a M/M process of a carbide alloy to have high resistance to corrosion and wear. The torpedo has a conical front surface which forms a pointed tip and a melt channel extending to an outlet on the conical front surface. The melt channel has a central rear portion extending from an inlet on the surface of the torpedo and a diagonal front portion extending from the rear portion to the outlet. The diagonal front portion of the melt channel is tapered inwardly enough to offset the diagonal at which it extends to allow for free ejection of the molded torpedo from its mold. This requires that the taper be enough that the shortest longitudinal line along the inner surface forming the melt channel does not diverge outwardly anywhere along its length.
摘要翻译：一种注射成型的鱼雷，其本身可以通过M / M过程的碳化物合金进行注射成型，具有较高的耐腐蚀和耐磨性。鱼雷具有一个圆锥形的前表面，它形成一个尖头和一个延伸到锥形前表面上的出口的熔体通道。熔体通道具有从鱼雷表面上的入口延伸的中央后部和从后部延伸到出口的对角线前部。熔体通道的对角线前部向内倾斜，足以抵消其延伸的对角线，以允许模制鱼雷自由地从其模具中弹出。这要求锥度足以使得沿着形成熔体通道的内表面的最短纵向线沿着其长度向外发散。
