A plc-based automatic production control system for die-casting

Abstract

A PLC-based die-casting automatic production control system is characterized in that the system includes a PLC module, a feeding module, a die-casting module, a blanking module and a packing module; the PLC module is a main controller for feeding Module, die-casting module, unloading module and packaging module are controlled; the feeding module includes a feeding machine device and an automatic weighing device for feeding and weighing the powder, and when the powder reaches the preset weight After that, it is delivered to the die-casting module; the die-casting module is used to die-cast the powder transferred from the feeding module through the mold, and the finished product of the die-casting is sent to the unloading module; The die-casting finished product is received on the module, the mold is separated from the die-casting finished product, and the mold is put into the die-casting machine cavity of the die-casting module again; the packaging module is used to grab and separate the mold from the blanking module Finished products, and the finished products are stacked and palletized.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a PLC-based die-casting automatic production control system. Background technique [0002] At present, most of the whole process of brake pad die-casting requires manual participation: the operator needs to use an appliance to hold the powder, weigh it with an electronic scale, and then manually pour it into the cavity of the die-casting machine after weighing; then, the operator operates the die-casting machine to die-cast After the die-casting is completed, manually push the finished product and the mold out of the mold cavity, separate the finished product and the mold with tools, put the mold back into the die-casting machine cavity, and then manually remove the slag and pack the finished product; repeat the above process again; the current manual This method mainly has the following disadvantages: [0003] Manual feeding, weighing efficiency is low, and die-casting processi...

AI Technical Summary

Problems solved by technology

[0003] Manual loading, low weighing efficiency, and die-casting processing accuracy is closely related to weighing accuracy. In the existing method, the weighing weight is confirmed by people observing the electronic scale. The weighing accuracy is related to the worker's professional attitude, physical strength and experience It is difficult to guarantee;

[0004] The powder for die-casting is composed of chemical polymer materials and has the characteristics of dust. Workers will inhale a large amount of chemical dust during the feeding process, which will cause great damage to the body;

[0005] At the same time, because the die-casting process is a process of high temperature and high pressure, the noise pollution is serious, and the production environment is particularly harsh. Many factories now have difficulties in recruiting workers;

[0006] The weight of the mold and the finished product is relatively large, and the labor intensity of the workers in the production process is relatively high, and the mold needs to be put back into the cavity manually. The temperature in the cavity of the die-casting machine is very high, and there are certain safety hazards;

[0007] The processes of loading, unloading and moving molds in die-casting production are all carried out by one operator, which cannot be carried out in parallel, and the production efficiency is low;
