摘　　要：开发了一种多通道的压力为0.6 MPa、最高加热温度为160℃、流量为50 L/min的高压过热水模温控制装置(水式模温机),具有模具预热、模具冷却、自动补水、自动稳压和自动温控等功能。试验结果表明:在短时间内,该装置能迅速将模具温度预热到100℃以上,比传统的油式模温机提高约60℃;将模具预热到同一温度,其加热时间比油式模温机减少约50%,节能约40%。因而具有很好的模具预热效率和预热速度,使用方便、节能、不污染现场环境等优点。该装置已成功应用于某复杂通讯框体压铸件的生产上,效果良好,取代了油式模温机。A kind of temperature controller （water-based die temperature controller） based on high pressure and overheated water has been developed, with the pressure of 0.6 MPa, maximum heating temperature of 160 ℃ and flow rate of 50 L/min. It has functions such as pre-heating and automatic cooling, water charging, pressure stabling and temperature control, etc. The experimental results show that the die temperature can be preheated to 100℃ in a short time, which is approximately 60 ℃ higher than that of conventional oil temperature controller. Meanwhile, pre-heated time of die can be reduced by 50%, compared to oil temperature controller at the same temperature. Consequently, the equipment has some advantages, such as higher heating efficiency, faster heating-velocity, energy saving and no pollution etc. The apparatus was successfully applied to a complicated communication frame casting instead of oil temperature controller.
