Die-casting machine clamping mechanism directly driven by frameless permanent magnet synchronous motor

Abstract

The invention discloses a die-casting machine clamping mechanism directly driven by a frameless permanent magnet synchronous motor. The die-casting machine clamping mechanism comprises an installing plate, a guide post, a movable die plate and a fixed die plate, wherein the installing plate is connected with the fixed die plate through the guide post; the movable die plate is provided with a guidehole matched with the guide post and is connected with the guide post in a sliding mode through the guide hole; a thrust screw is fixedly connected with the movable die plate, and a nut fixed to a motor installing seat through a bearing and matched with the thrust screw rotates to provide thrust force for the thrust screw; the motor installing seat is fixed to the installing plate; and the nut isdirectly driven by the frameless permanent magnet synchronous motor. According to the die-casting machine clamping mechanism directly driven by the frameless permanent magnet synchronous motor, a middle transmission component is omitted, the structure is simple, the transmission efficiency is high, and the torque is large.

Description

technical field [0001] The invention relates to the technical field of workpiece processing equipment, in particular to a die-casting machine mold locking mechanism directly driven by a frameless permanent magnet synchronous motor. 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, die-casting technology has developed extremely rapidly in various aspects. [0003] At present, there are more and more types of die-casting machines, more and more perfect functions, and more and more complex structures. As the core mechanism of die-casting machines, the mold clamp...

Problems solved by technology

[0003] At present, there are more and more types of die-casting machines, more and more perfect functions, and more and more complex structures. As the core mechanism of die-casting machines, the mold clamping mechanism is generally composed of hydraulic pressure, gears, connecting rods and other transmission devices. There are many links, and the efficiency and accuracy of the transmission are greatly lost. At the same time, due to the increase in the number of transmission components, the performance is affected, which also leads to more difficulty in design, manufacture and assembly, and an increase in cost.
