An all-motor-driven precision molding machine and its operating method

Abstract

Provided are a fully motor-driven precision compression molding machine and an operation method. The compression molding machine comprises a console (100) and a feeding component (200), a compression molding machine body (300), a discharging component (400), and a rack component (500). The feeding component is configured to feed a die and a preform into the compression molding machine body. The compression molding machine body is configured to process the preform. The compression molding machine body comprises a molding mechanism (310), a shift fork mechanism (340), a forming cabin (350), and nitrogen delivery ports (360). A plurality of nitrogen delivery ports is disposed outside the compression molding machine body for inputting nitrogen into the forming cabin to ensure that the nitrogen concentration exceeds a critical point after a certain period of time so as to form a protective atmosphere, thus preventing the preform and the die from being oxidized at high temperature. The discharging component is configured to deliver an assembly out of the compression molding machine body. The driving mode has high control precision and ease of operation.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to an all-motor-driven precision molding machine. Background technique [0002] As we all know, there is a huge market demand for optical lenses such as spherical, aspherical, and free-form surfaces, optical microstructures such as microprism arrays, microlens arrays, and micro-groove arrays, and optical devices with complex curved surfaces such as Fresnel lenses. It is made of optical materials such as optical glass and infrared glass. At present, optical device processing can be divided into the following three categories: [0003] The first category is the use of mechanical processing, mainly including single-point diamond turning, ultra-precision grinding and various polishing processes. Machining methods can process most optical components, and can achieve extremely high processing accuracy. [0004] The second category is the use of photolithography processin...

AI Technical Summary

Problems solved by technology

The optical material molding machine tool developed by thermoforming technology has already been commercialized; however, most of the molding mechanisms on the market use cylinders, which have problems such as low control accuracy of mold clamping speed, position and forming force. It directly affects the improvement of technical indicators such as surface accuracy and roughness of molded products; at the same time, the pneumatic drive needs to be equipped with an independent compressed air supply system, and additional air compressors, voltage stabilization and drying and filtering equipment are required, which increases the cost of system equipment; in addition The current molding machine is mainly controlled by PLC. Although its stability is relatively good, its computing power is far inferior to that of an industrial PC inserted into a motion control board, and its response speed and controllable degree of freedom are not high.
