Internet-of-things monitoring system applicable to mold and method thereof

Abstract

The invention discloses an internet-of-things monitoring system applicable to a mold. The internet-of-things monitoring system applicable to the mold comprises a cloud server, a client and a mold terminal. The mold terminal comprises a control module, a communication module, a mold assembly travel switch sensor, an ejector pin position sensor, a temperature sensor and a pressure sensor. The communication module, the mold assembly travel switch sensor, the center position sensor, the temperature sensor and the pressure sensor are in communication connection with the control module respectively.The mold assembly travel switch sensor is arranged to detect the mold assembly state and the mold opening state of the mold. The center position sensor is arranged to detect the position state of anejector pin. The temperature sensor is arranged to detect the working temperature of the mold. The pressure sensor is arranged to detect the changes of the pressure in a mold cavity. The control module is arranged to receive and process detected data. The internet-of-things monitoring system applicable to the mold achieves real-time monitoring on the working state of the mold, and is higher in accuracy of mold monitoring.

Description

technical field [0001] The invention relates to the field of mold monitoring, and more specifically relates to an IoT monitoring system and method suitable for molds. Background technique [0002] As we all know, a mold is a tool used in industry to make shaped items, and the shape of the item can be processed by changing the physical state of the formed material. The mold is a tool with extremely high precision. It has a complex shape and bears the expansion force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is at the level of mechanical manufacturing. One of the important symbols. In the actual production operation, the state of mold closing and opening, the working state of ejector pin, the working temperature in the mold, and the pressure change in the mold are all related to whether the mold can work normally. On the other hand, the cost ...

Problems solved by technology

[0003] However, there are still some problems in the existing traditional technology for the monitoring means of the mold

A traditional method is to install parts and equipment outside the mold to collect mechanical and physical data on the mold. The collection process needs to be completed manually, the degree of automation is not high, and the regularity of data collection is also poor. The poor visibility of the results is not conducive to the operator to make accurate monitoring judgments in time

[0004] Another method is to use the injection molding machine to directly access the production data of the mold, but this method is an indirect data monitoring method. There is a certain error between the obtained monitoring data and the real data inside the mold, resulting in poor monitoring effect. Difference

[0005] It is worth mentioning that neither of the above two traditional mold monitoring methods can upload the detection data to the Internet, and cannot realize the remote monitoring of the mold by the operator
