example 1

[0048] Example 1: Debugging process in "manual" mode (delayed unloading function)

[0049] When debugging a certain technological process, the execution process between any two actions at this time is as follows: Figure 5 shown.

example 2

[0050] Example 2: Batch processing of castings in "automatic" mode:

[0051] The die-casting machine starts the die-casting action according to the set die-casting process. At the same time, the computer samples the analog signals of various sensors, and through A / D data conversion, the sampling of the injection stroke, injection speed and injection pressure is displayed on the computer screen in real time. data curve ( image 3 ), and record and calculate various technical parameters of the current working conditions, such as mold clamping force, maximum pressure, pressure building time, etc.; when a product die-casting is completed, the computer will automatically save the test data with the die-casting production time of the product as the file name save.

Abstract

A computer aided measuring and controlling system for compression casting is composed of compression casting machine, pressure sensor, displacement sensors, switching element, action executor, optically isolated multi-channel input board, multi-channel relay output board, digital I / O board, DC power supply for said sensors, analog signal connecting terminal board, analog I / O board and industrial control computer. It has three working modes: regulation, manual and automatic.

Description

technical field [0001] The invention relates to a die-casting machine measurement and control system and a control method thereof, in particular to a die-casting machine control and test system based on a Windows graphic interface, which belongs to the category of digital manufacturing. Background technique [0002] The quality of die-casting parts is directly related to many process parameters in the die-casting process, such as the closing force of the die-casting machine, injection force, injection speed, pressurization time, etc. At present, most of the action control of the die-casting process uses a programmable logic controller (abbreviated as PLC) as the main control computer. Chinese patent CN02250448.6 "Intelligent control device for die-casting machine" includes a touch screen, a programmable controller, a digital-to-analog converter, a proportional amplifier, and an operating switch. The touch screen displays the machine's operating conditions and fault alarms. ...
