Abstract

The invention discloses an automatic material taking system of a die-casting machine with a mould safety monitoring device. The system provided by the invention comprises the automatic material taking system of the die-casting machine, and further comprises a safety monitoring device, wherein the safety monitoring device comprises a weighting disc, a support rod and a control platform of the safety monitoring device; the weighting disc is fixed on the control platform of the safety monitoring device through the support rod, the control platform of the safety monitoring device is provided with a weighting sensor, the safety monitoring device and the automatic material taking system of the die-casting machine are connected with a PLC (programmable logic controller) control system and controlled by the PLC control system. The weighting sensor can transmit the signals which are processed by a microprocessor of the safety monitoring device to the PLC control system while sensing the signals, which is different from the property of the normal weighting electronic balance needing a longer stabilization time after being impacted by heavy objects. Because the safety monitoring device adopts the combined detection method of combining the compact force detection with the weight detection under the steady states to obtain the weight of the shortest cast piece, the high-speed production of the full automatic material-taking die-casting machine can be ensured.

Description

technical field

[0001] The invention relates to an automatic feeding system of a die-casting machine equipped with a mold safety monitoring device and a casting quality judgment method. Background technique

[0002] With the improvement of the automatic control system level of mechatronics, more and more die-casting machines have begun to use the automatic reclaiming system of die-casting machines instead of manual automatic reclaiming. The automation system reduces labor costs, improves the quality of the working environment, and reduces the labor intensity of workers. However, the automation system also loses the high-intelligence monitoring ability of manual operation. The typical problem is: the automatic retrieving process of the die-casting machine automatic retrieving system may cause incomplete retrieving. Once the casting is not completely removed from the mold, and the die-casting machine starts the next casting process and performs the mold clamping operation, th...
