High-temperature die-casting water temperature machine

Abstract

The invention relates to a high-temperature die-casting water temperature machine. The high-temperature die-casting water temperature machine comprises a heat exchanger, a cooling water inlet, a cooling water outlet, a hot water inlet, a hot water outlet, a pressure relief opening, a water supplementing opening and an air blowing device, wherein a first pipeline is connected between the cooling water inlet and the cooling water outlet, and a second pipeline is connected between the hot water inlet and the hot water outlet; the first pipeline and the second pipeline are connected with the heat exchanger, the first pipeline is connected with a first electromagnetic valve and a one-way valve, the second pipeline is sequentially provided with a programmable logic controller (PLC)control unit, a check valve, a magnetic pump and a first angle seat valve, the water supplementing opening is connected with a third pipeline, the other end of the third pipeline communicates with the second pipeline, and the third pipeline is sequentially provided with a water supplementing pump, a second electromagnetic valve and a second one-way valve; and the air blowing device is connected with the second pipeline, a pressure relief device is arranged on the second pipeline, and the second pipeline at the hot water inlet is connected with the second pipeline at the hot water outlet through a fourth pipeline. The high-temperature die-casting water temperature machine has the following advantages that pressure fluctuation is prevented, dry burning is prevented, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of temperature control and mold temperature machine, in particular to a high-temperature die-casting water temperature machine. Background technique [0002] As a mold temperature controller for die-casting machines, the water temperature controller for die-casting machines is widely used in the die-casting industry, but the current water temperature controller still has some shortcomings, such as high temperature and large fluctuations in internal pressure; use For the heating barrel, it is necessary to ensure that there is water in the heating barrel to prevent dry burning. Due to the characteristics of the water temperature machine, the water will vaporize when the temperature is higher than 100°C, so it is necessary to ensure that the water level in the heating barrel is kept in a safe range to avoid abnormalities.
