Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0022] The general mold use is divided into: feeding - die casting - demoulding - cooling - feeding, so several steps and continuous cycle.

[0023] Such as figure 1 As shown, when the mold temperature field automatic adjustment control device of the present invention starts to work, it first performs a cold start. During the cold start, the electric heater in the heating link quickly heats the working medium oil from the working medium storage tank, and heats the heated...

Abstract

The invention discloses an automatic adjustment control device for a mold temperature field, which solves the problem that the conventional thermocouple can conduct point measurement and cannot comprehensively measure the distribution of mold temperatures by acquiring temperature field information of a mold through an infrared shooting mode. The automatic adjustment and control device can perform continuous process control on the mold and adjust the temperature field of the mold in real time so as to ensure the stability of the temperature field of the mold in production.

Description

technical field [0001] The invention relates to a mold temperature field automatic adjustment control device, which belongs to the technical field of electromechanical measurement and control. Background technique [0002] During the production process of metal casting or plastic injection molding, it is necessary to strictly control the temperature field of the mold to ensure the quality of casting products. Cast finished products often have different structures, varying in volume and shape. In the mold design process, the internal temperature change process must be considered. Therefore, the mold has theoretical and empirical guidance on the injection port and the flow process of liquid materials, but it lacks effective detection and control methods for the control of the internal temperature field. The existing control methods are: one is to use a mold temperature controller, and the other is to spray regularly and quantitatively. The premise of the assumption is that a...
