【摘要】：模具加熱是液體浸塑工藝中的重要環(huán)節(jié),其包括火焰加熱、電加熱、紅外線加熱等多種方式。紅外線加熱因其具有穿透性、熱效率良好、升溫迅速、溫度易于控制等優(yōu)點,在近幾年以很快的速度應(yīng)用于各個領(lǐng)域。某型號紅外線加熱爐,對模具加熱效率不夠高,而且模具溫度分布也不夠均勻。效率不高不僅造成一定程度的資源浪費,而且使得工作條件變得較差。而模具溫度分布不均勻,就會使得一些產(chǎn)品不符合要求。所以,對模具加熱過程進行熱分析,進而提出模具加熱裝置的改進方案,對于提高模具加熱的熱效率并改善熱均勻性,是很有意義的。 本文通過有限元軟件ANSYS模擬加熱爐對模具的加熱過程。先使用三維軟件建模,得到加熱裝置和模具的三維模型,之后用ANSYS流體模塊進行分析,得到爐內(nèi)溫度場分布,并以此為條件進行穩(wěn)態(tài)和瞬態(tài)耦合熱分析,得到模具加熱一定時間后的溫度分布,為加熱設(shè)備的優(yōu)化提供依據(jù)。 結(jié)合傳熱學(xué)相關(guān)知識和有限元分析結(jié)果,提出加熱爐優(yōu)化方案,并對方案進行比較,提出最優(yōu)方案。經(jīng)過驗證,改進后的加熱設(shè)備能較為明顯地提高加熱效率,也能在一定程度上改善熱均勻性,為實際生產(chǎn)提供了理論指導(dǎo)。
[Abstract]:Mold heating is an important part of liquid immersion process, which includes flame heating, electric heating, infrared heating and so on. Infrared heating is widely used in various fields in recent years because of its advantages of penetration, good thermal efficiency, rapid heating and easy temperature control. A certain type of infrared heating furnace, the mold heating efficiency is not high enough, and mold temperature distribution is not uniform. Inefficiency not only causes a certain degree of waste of resources, but also makes working conditions worse. And mold temperature distribution is not uniform, will make some products do not meet the requirements. Therefore, it is of great significance to analyze the heating process of the die, and then to put forward the improvement scheme of the heating device of the mould, which is of great significance to improve the heat efficiency and the uniformity of the heating of the mould. In this paper, the finite element software ANSYS is used to simulate the heating process of the heating furnace. The three-dimensional model of heating device and mould is obtained by using 3D software, and then the temperature field distribution in furnace is obtained by using ANSYS fluid module, and the steady and transient coupled thermal analysis is carried out under this condition. The temperature distribution of the mould is obtained after heating for a certain time, which provides the basis for the optimization of heating equipment. Combined with the knowledge of heat transfer and the results of finite element analysis, the optimization scheme of heating furnace is put forward, and the optimum scheme is put forward by comparing the scheme. It is proved that the improved heating equipment can obviously improve the heating efficiency and improve the thermal uniformity to a certain extent, which provides theoretical guidance for practical production.
