摘要:
A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.

A magnetic-inductive flowmeter with a measuring tube, a magnetic field generator and a measuring electrode in which its measuring electrodes are improved is achieved by the measuring electrode being of an outer electrode sheath of an electrically non-conductive plastic and of an inner electrode core of electrically conductive plastic and by the a method for producing the measuring electrode.
摘要:
A pre-wired injection molding assembly to be supplied to the customer for installation in a mold. The assembly includes a number of sub-manifolds connected to a main manifold, a wiring frame having a number of elongated fingers connected to the sub-manifolds, and a number of heated nozzles connected to the sub-manifolds. The fingers of the wiring frame extend from a hollow channel member which leads to a connector box. The assembly is pre-wired by the supplier by running the wires from the nozzles along the fingers and through the channel member to the connector box. The pre-wired assembly is mounted from the rear in a matching mold manifold plate which greatly facilitates installation and disassembly for the customer.
