摘要： One or more nozzles define separate nozzle channels. The nozzles are coupled to a manifold, so that each of the nozzle channels communicates with a different mold gate. A molding material distribution insert is coupled to the manifold and has a body defining a distribution channel and a plurality of drop channels equal in number to the nozzle channels. The distribution channel is an open distribution channel formed on an outer surface of the body and enclosed by the manifold. The drop channels intersect the distribution channel and exit the body at a different one of the nozzle channels. A valve pin bushing can extend into the drop channels. Valve pins can extend from actuators, through the valve pin bushing and the drop channels, and to the mold gates. A valve pin holder can be coupled to the actuator and coupled to heads of the valve pins.

摘要： Injection-moulding device (1) with a feed plate (3), in which at least one flow channel (4) for a flowable material is formed, with at least one needle valve nozzle, through which the flowable material can be fed in continuation of the flow channel to a separable mould insert, with at least one shut-off needle (20), at least a portion of which passes through the flow channel in a longitudinally displaceable manner and which can be brought by means of a drive into an open position and a closed position, and with a guide bush (30) for leading the shut-off needle (20) through and sealing it. The guide bush has a region which encloses the shut-off needle with a small amount of play and at least a portion of which lies in the flow channel. The region thereby has a contact surface for the flowable material, at least a portion of which lies in the flow channel. The region and the contact surface (44) are flowed around by flowable material on all sides.

摘要： An injection molding system is disclosed having a self-regulating valve for balancing melt flow. The self-regulating valve includes a control rod configured to balance the melt flow rate through a hot runner system. The self-regulating valve reacts to an injection or melt pressure within the hot runner system and a pre-set force provided by an external force device. The self-regulating valve is an open-loop system as it requires neither a measurement of pressure by a sensor nor feedback from a processor in order to regulate the melt flow. The self-regulating valve mechanically reacts to changes in melt pressure on control surfaces thereof by "bobbing" upwards/downwards to decrease/increase the melt flow accordingly. The self-regulating valve compensates for conditions that affect melt pressure, such as an increase/decrease in melt viscosity, changes in melt temperature, and/or mold cavity size without the use of a processing device.
摘要翻译：公开了一种具有用于平衡熔体流动的自调节阀的注塑系统。自调节阀包括配置成平衡通过热流道系统的熔体流动速率的控制杆。自调节阀对热流道系统内的注入或熔融压力以及由外力装置提供的预设力作出反应。自调节阀是开环系统，因为它既不需要传感器的压力测量也不需要来自处理器的反馈来调节熔体流动。自调节阀通过“向上/向下”上下移动来对其控制表面上的熔体压力的变化进行机械反应以相应地降低/增加熔体流动。自调节阀补偿影响熔体压力的条件，例如熔体粘度的增加/降低，熔体温度的变化和/或模腔尺寸，而不需要使用加工装置。
