Abstract

The invention provides an injection pressurizing structure of a die-casting machine, comprising an injection piston rod, an injection piston, a card opening ring, a nut, a pressurizing piston rod, an injection valve plate, a pressurizing valve plate and a guide sleeve, wherein the injection valve plate is provided with an injection oil path. The injection pressurizing structure is characterized in that the injection pressurizing structure of the die-casting machine further comprises a rapid injection valve plate arranged on the injection valve plate; the rapid injection valve plate is provided with a rapid injection oil path; the injection valve plate and the rapid injection valve plate are provided with a two-way plugging-in valve; the two-way cartridge valve comprises a two-way plugging-in throttling valve and a hydraulic control one-way valve; the two-way plugging-in throttling valve is connected with a rapid injection oil path through an oil pipe; and the hydraulic control one-way valve is connected with an injection oil path through an oil pipe. The injection pressurizing structure of the die-casting machine has the advantages of fast pressurizing speed, short pressure establishing time, good sealing effect and uneasiness of being leaked, and enables an injection system to have a more stable pressure-keeping effect.

Description

Technical field: [0001] The invention relates to the technical field of die-casting machines, in particular to an injection pressurized structure of a die-casting machine. Background technique: [0002] The injection system of the die-casting machine is a key component that determines the product performance of the die-casting machine. At present, the traditional die-casting machine basically adopts a double-circuit three-stage injection system that uses a floating piston to boost pressure. The installation and machining accuracy of the floating piston and the floating spool in this injection and booster structure require high precision. If the installation of the floating piston and the floating spool are not on the same axis, the sealing effect of the Bell line on the cone surface of the floating piston and the floating spool will Not good, it is easy to leak, resulting in unstable pressure holding. The supercharging piston pushes the floating spool to seal with the bell ...
