Title: Dragan Iliev Nenov: Innovator in Molding Technology
Introduction
Dragan Iliev Nenov is a notable inventor based in Sofia, Bulgaria. He has made significant contributions to the field of molding technology, holding a total of 4 patents. His innovative designs focus on improving the efficiency and effectiveness of molding processes.
Latest Patents
Dragan's latest patents include a machine for molding materials with a long solidification time. This injection molding machine features a support on a base that carries oppositely facing stationary mold portions. When joined by movable mold portions, these form a pair of mold cavities. One cavity can be injected with a moldable material that has a long solidification time, while the other contains a previously injected article that is solidifying. This design allows for the release of the article as soon as the injection of the first cavity is completed. Additionally, one of the movable mold portions is connected to a movable plate in a fixed spaced relationship, incorporating a wedge-type locking mechanism for simultaneous locking of both mold cavities.
Another of his patents is an apparatus for controlling the rate of filling of casting molds. This apparatus allows for the casting of molten material by utilizing two chambers under different pressures. A tube connecting these chambers delivers the molten material from one to the other based on a pressure differential. Signal-producing apparatus connected to the mold chambers generate signals representing the pressures and pressure differential. These signals are processed to control the pressures, thereby varying the rate of filling of the mold according to a predetermined program.
