Problems solved by technology

[0006] As we all know, the casting process of aluminum piston is a special process. In order to ensure the casting quality, the solidification process of molten aluminum needs a relatively stable beat. However, because there are many factors affecting the production process of aluminum piston, the mold temperature must be relatively stable in order to obtain a stable production beat. , the traditional above-mentioned mold temperature control methods obviously cannot meet the requirements of good mechanical properties and low casting rejection rate of aluminum piston castings

Abstract

The invention discloses a device for automatically controlling the temperature of an aluminium piston casting die in an on-line manner. The device comprises a central processing unit (CPU), wherein the CPU is connected with an OP (operator) panel, a temperature module and an I/O (input/output) module respectively; the temperature module is connected with a temperature sensor arranged in the aluminium piston casting die; and the I/O module is connected with a cooling controller installed on a cooling water inlet pipeline in front of the aluminium piston casting die. The invention also discloses a method for automatically controlling the temperature of the aluminium piston casting die in an on-line manner. According to the invention, the temperature of the aluminium piston casting die can be automatically controlled and stabilized in an on-line manner, at the same time, the casting production efficiency is high and the requirements for good mechanical properties and low casting reject rates of aluminium piston castings are met; and the device can intelligently control the temperature of the die without manual adjustment.

Description

[0001] technical field [0002] The invention relates to an on-line automatic mold temperature control device and method for blank casting of aluminum pistons for engines, in particular to an automatic mold temperature control device and method for blank casting of large-diameter diesel aluminum pistons (diameter Φ≥120mm). Background technique [0003] At present, when aluminum piston blanks are manufactured for engines, most of them adopt simple mechanical mold opening and closing production methods, and the control of the casting process is relatively backward, especially the production of large-diameter diesel pistons, most of which still use the manual workshop production method. This method is simple, but the production efficiency is low, the process stability is poor, and it is difficult to adapt to large-scale production and the requirements for high-quality products. [0004] In recent years, in order to improve the power performance of the engine, reduce fuel consum...
