Latest Patents

One of Yosif's latest patents is the Multi-level stacked mold system. This invention features an injection mold designed for use with a molding press that incorporates four mold levels in axially stacked relation. This design allows for a substantial doubling of output for a given size of press compared to traditional back-to-back two-level stacked molds. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the center of the stacked mold block series. The centrally located distribution block is connected in a sealed relation with the injector head, allowing for axial displacement while maintaining a sealed connection upon the opening of the mold.

Additionally, the mold includes a drool prevention valve system located at two of the mold interfaces. This system is designed to prevent the drooling of fluid plastic stock upon opening the molds. It features pressure fluid actuators for operating the valves, with the pressure fluid potentially comprising the fluid plastic stock. The valve system also includes a depressurizing valve provision, which reduces the tendency to drool by substantially depressurizing the stock distribution passages upon opening the mold interfaces. Furthermore, the mold is equipped with axial adjustment means to compensate for differential variations in overall mold length within the press due to changes in effective mold temperature.
