The invention provides a floating piston type injection pressurizing device. The floating piston type injection pressurizing device is characterized in that the floating piston type injection pressurizing device comprises a sealing cone, a pressurizing piston rod, a pressurizing valve port, a pressurizing piston, a pressurizing oil port, a fixed bolt, a pressurizing oil cylinder; and the pressurizing oil cylinder is included, the pressurizing piston is arranged in the pressurizing oil cylinder, the pressurizing piston is fixedly connected with the pressurizing piston rod through the fixed bolt, the sealing cone is mounted at the other end of the pressurizing piston rod for sealing, the pressurizing valve port is mounted at and connected to the other end of the pressurizing piston, and thepressurizing oil port is formed in the middle of the pressurizing valve port. The floating piston type injection pressurizing device has the advantages that the floating piston type injection pressurizing device is simple in structure, reasonable in principle, easy to manufacture, low in manufacturing cost, and convenient to mount and maintain, and the problem that under the situation of pressurecontrol, the speed is instable during in-advance pressurizing and travel control pressurizing can be solved.
Description
technical field [0001] The invention relates to the technical field of die-casting machine components, and in particular provides a floating piston injection booster device. Background technique [0002] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold under pressure to cool and form it, and obtain solid metal castings after the mold is opened. It was originally used for die-casting characters. With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, and starting from energy saving and saving raw materials, die-casting technology has achieved extremely rapid development. The core component of the die-casting machine is the injection device. The existing injection device has complex structure, difficult manufacture, complicated installation and maintenance, resulting in high manufacturi...
