摘要： An injection mold characterized by relative simplicity, compact size, and capability of relatively high rate production of molded parts without runners which must be removed to finish the parts. A molten molding medium is fed to each mold cavity through a heated hot box and an injection nozzle contained within an injection chamber which communicates with the cavity through a gate opening in the cavity wall. The nozzle has a tip which enters the gate opening to define an annular injection orifice between the nozzle tip and the edge of the gate opening, and the nozzle seats slidably on the hot box to effect self-centering of the nozzle tip in the gate opening and sealing of the nozzle to the hot box by the pressure of the molding medium about the nozzle and heat transfer from the hot box through the nozzle to the medium to retain the latter at the proper molten temperature. The mold has mold cavities symmetrically arranged at opposite sides of the hot box and intersected by parting planes between mold sections which are separable to permit stripping of the molded articles from the cavities.
