Water type mold temperature machine is a mold temperature machine that uses water as the circulating medium. It is widely used in temperature control equipment such as molds, rollers, reaction kettles, injection molding, extrusion, etc. due to its unique advantages of high energy efficiency, low cost, simple maintenance, and no pollution. PID automatic temperature control mold temperature machine, divided into 120 ℃ and 180 ℃ high-temperature water mold temperature machines.

The equipment consists of water tanks, heating and cooling systems, power transmission systems, liquid level control systems, as well as temperature sensors, injection ports, and other components. Usually, the pump in the power transmission system causes the hot fluid to reach the mold from the water tank equipped with a built-in heater and cooler, and then return to the water tank from the mold; The temperature sensor measures the temperature of the hot fluid and transmits the data to the controller of the control section; The controller regulates the temperature of the hot fluid, thereby indirectly adjusting the temperature of the mold. If the temperature of the mold exceeds the set value of the controller during production, the controller will open the solenoid valve and connect the water inlet pipe until the temperature of the hot liquid, that is, the temperature of the mold, returns to the set value. If the mold temperature is lower than the set value, the controller will turn on the heater.

The water mold temperature machine adopts imported electrical accessories such as West, ABB, CARLO, LS, SCHNEIDER, etc. It has more than 10 safety protection measures such as water shortage protection, phase sequence detection, and pump overload protection. The high temperature can reach 180 ℃, with high heat transfer efficiency and low pollution. It is widely used in the injection molding, extrusion, and reaction kettle industries.

Principle:

The equipment consists of an electric heating tube, a temperature sensing probe, a high-temperature water pump, an electromagnetic valve, a pressure controller, etc. After starting to work, the water pump drives the water circulation flow, the electric heating tube heats, flows through the equipment that needs to be heated, and then transfers the heat to the heating equipment. Set the heating temperature through the temperature control meter, and stop heating when the temperature sensing probe detects that the current water temperature is consistent with the set temperature. Has good thermal conductivity, clean and pollution-free. It is often used for temperature control in industries such as injection molding, rubber rolling, roller, extrusion, bottle blowing, printing, and chemical reaction kettles.
