    • A side gate nozzle assembly for a hot runner apparatus comprises a disc shaped base body, a probe member, a sealing insulator, and a shape memory alloy washer. The probe member with a probe channel extends from the base body. A molten molding material is received through a melt channel of the nozzle body, and allowed to pass through the probe channel to be transferred to a cavity of a cavity member. The shape memory alloy washer is positioned between the base body and the sealing insulator. The shape memory alloy washer distorts linearly to push the sealing insulator and the probe member according to change in temperature due to the transfer of the molten molding material from the melt channel to the cavity member via the probe channel. The distorted shape memory alloy washer prevents leakage of the molten molding material from the melt channel, and the probe channel.
    • 用于热流道装置的侧浇口喷嘴组件包括盘状基体,探针构件,密封绝缘体和形状记忆合金垫圈。 具有探针通道的探针构件从基体延伸。 熔融的模制材料通过喷嘴主体的熔体通道被接收,并且被允许穿过探针通道以被传送到空腔构件的空腔。 形状记忆合金垫圈位于基体和密封绝缘体之间。 形状记忆合金垫圈线性扭曲以根据由于熔融成型材料经由探针通道从熔体通道传递到腔体构件而引起的温度变化来推动密封绝缘体和探针构件。 变形的形状记忆合金垫圈防止熔化的成型材料从熔体通道和探针通道泄漏。

    • In a manifold, the valve pin has a sealing surface proximate its bottom end, which surface is engageable with a gate sealing surface to inhibit melt flow into the cavity. A first guidance and alignment structure is connected to the valve pin, and a second structure to the mould block upstream from the gate. Both structures include first and second guide surfaces of a diameter decreasing gradually in a downstream direction and first and second cylindrical alignment surfaces. The first guide surface is positioned immediately downstream from the first alignment surface, the second guide surface immediately upstreams from the second alignment surface. The second guide surface is positioned to complete alignment of the valve pin with the gate prior to contact between valve pin and gate. Further, it is positioned to engage the first alignment surface to maintain the valve pin in alignment with the gate during its movement towards the gate.
