Definitions

  • Die-casting machine by driving the injection plunger provided in the injection device forward every shot, injects and fills a predetermined amount of molten metal material such as Al alloy or Mg alloy into the mold cavity, and then forms the required shape. It is a molding machine that molds products. Die-casting machines also have a low-speed injection process, a high-speed injection process, and a pressure-increasing process (in the case of an injection molding machine), similar to an injection molding machine that molds a plastic material into a mold cavity to form a product of the required shape. The molding material is injected and filled into the mold cavity through a pressure holding process.) The die casting machine has an injection speed in the high-speed injection process that is about one digit faster than the injection molding machine. There are features. For this reason, conventionally, a hydraulic die casting machine provided with a hydraulic injection device that drives an injection plunger by hydraulic pressure has been mainstream.

Abstract

L'invention a pour objectif de fournir une machine électrique à couler sous pression qui est miniaturisée, et qui est capable d'empêcher une surpression survenant dans un métal en fusion injecté pour remplir l'intérieur d'une cavité de moule. Un dispositif électrique d'injection (1) de cette machine électrique à couler sous pression est configuré de sorte qu'il contient : un axe fileté (5) maintenu de manière à pouvoir exercer une rotation; un corps d'écrou (7) vissé sur l'axe fileté (5), et entraîné dans un déplacement en avant / en arrière selon l'entraînement rotatif de l'axe fileté (5) ; un piston d'injection (9) entraîné dans un déplacement en avant / en arrière selon le déplacement en avant / en arrière du corps d'écrou (7) ; une barre de guidage (6) qui conduit le corps d'écrou (7) et le piston d'injection (9) dans la direction de déplacement en avant / en arrière ; et un servomoteur électrique pour injection (10) entraînant en rotation l'axe fileté (5). Un dispositif amortisseur d'impact (31) qui se déforme élastiquement sous l'influence de la surpression agissant sur le piston d'injection (9), est placé entre le corps d'écrou (7) et la barre de guidage (6).
