摘　　要：国内外模温机普遍为油式或水式模温机,目前多数模温机不能兼容水和热煤油,对一些工厂空间规划要求高以及中小型企业来说,能够同时水油两用的模温机可以极大降低工厂的生产成本并节省工厂占地空间。国内现有的水油两用模温机普遍存在不能自动补水,到低液位时直接报警停机以及开机重复补水的问题,导致机器无法长时间运行,为了解决这种弊端,在水油两用模温机上增加了双段液位提醒功能,水箱液位下降到第一阶段时启动液位偏低报警并自动补水,水箱液位下降到第二阶段时启动低液位报警并自动停机;通过水泵逆转简化了模具排空功能,与传统结构相比成本更低、使用更简便;结合热量传递与机器电热功率推导了流量计算公式;测试验证了机器电热功率可调,实现了一机多用、操作简便的设计要求。At present,both domestic and foreign mold temperature machines are generally oil or water type,and there is rarely a mold temperature machine that is compatible with water and heat medium oil.For some factories with high space planning requirements and small and medium-sized enterprises,a mold temperature machine that can simultaneously use water and oil can greatly reduce the production cost of the factory and save factory space.Currently,the existing water and oil dual-purpose mold temperature machines in China generally have the problem of not being able to automatically replenish water,directly alarming and stopping when the liquid level is low,and repeatedly replenishing water when starting up,resulting in the inability of the machine to operate for a long time.In order to solve this problem,a dual stage liquid level reminder function is added to the water and oil dual-purpose mold temperature machine,that is,when the water tank level drops to the first stage,the machine starts a low liquid level alarm and automatically replenish water.When the water level drops to the second stage,the machine starts a low liquid level alarm and automatically shut down.The mold emptying function is simplified by reversing the water pump,which is lower in cost and easier to use compared to traditional structures.A flow calculation formula is derived by combining heat transfer with machine electric heating power.The test verified that the machine's electric heating power is adjustable,achieving the design requirements of one machine for multiple uses and easy operation.
