Embodiment Construction

[0022] The following will be further described in conjunction with the accompanying drawings, not to limit the scope of the present invention.

[0023] see figure 1 Shown, the present invention comprises mold temperature machine 30, computer, mould, controller and data conversion device 3, and sensor 2 is installed in the mold cavity 1 of mould, and the workflow of the present invention is:

[0024] If the sensor 2 is a temperature sensor, the temperature analog signal enters the data conversion device 3 through the analog signal input line 5 and the analog signal input port 4 .

[0025] If the sensor 2 is a pressure sensor, the pressure analog signal enters the data conversion device 3 through the analog signal input line 5 and the analog signal input port 4 .

[0026] The sensor 2 is a humidity sensor, and the humidity analog signal enters the data conversion device 3 through the analog signal input line 5 and the analog signal input port 4 .

[0027] For the above analog ...

Abstract

The invention relates to an online die temperature monitoring device. The online die temperature monitoring device comprises a computer, a die, a controller, a die temperature controller and a data conversion device. A sensor is arranged in a die cavity of the die. The sensor is connected with one end of an analog signal input line, and the other end of the analog signal input line is connected with an analog signal input port of the data conversion device. A digital signal outlet is formed in the data conversion device. The controller is provided with a controller data inlet. The digital signal outlet is connected with the controller data inlet through a digital signal line. The sensor can collect temperature information, pressure information and humidity information and control the die. The online die temperature monitoring device is simple, efficient and practical.

Description

technical field [0001] The invention relates to injection molding equipment, in particular to an online mold temperature monitoring device. Background technique [0002] In the existing plastic molding process, there is no equipment to directly detect the surface temperature (or pressure) of the mold cavity. In the molding process, if the surface temperature (or pressure) of the mold cavity cannot be accurately grasped, the accurate molding process parameters will not be grasped. Since the plastic molding temperature fluctuates in a curve, if the temperature fluctuation curve cannot be accurately tracked, the molding process parameters will not be accurately determined, which will cause wrong guidance for future work, so it is necessary to obtain the operating parameters and accurate data of the mold temperature machine. At present, there is no similar technology in China; relatively speaking, the hot runner control technology is close. Hot runner control can only detect t...
