Problems solved by technology
This method is simple, but there are many problems, such as the temperature detection and temperature adjustment can not be synchronized, the lack of electric control valves, and the lack of heat exchange capacity lead to the temperature can not be dropped or increased in time
In the conventional mold temperature controller, the liquid flows in the pipeline, and the pressure and flow cannot be effectively controlled, resulting in unstable temperature regulation and affecting the life and quality of the mold.
In addition, the drainage system of the conventional mold temperature controller is not perfect, resulting in residual liquid remaining in the pipeline, which accelerates the aging speed of the equipment

The invention discloses a low-temperature mold temperature controller, and relates to the technical field of temperature control. The low-temperature mold temperature controller comprises a pipeline system and an appliance control system; the pipeline system comprises a main circulating water loop, a refrigerant supply pipeline system, a refrigerant returning and cooling draining pipeline system, a pressure PID (Proportion Integration Differentiation) adjusting system, a temperature PID control system and a draining pipeline; the appliance control system comprises a main control chip, a pressure controller and a temperature controller; the main circulating water loop is provided with an electric two-way pressure regulating valve; and an electric three-way temperature adjusting valve is arranged between the refrigerant supply pipeline system and the main circulating water loop. With the adoption of the low-temperature mold temperature controller disclosed by the invention, the water temperature and pressure can be effectively controlled, therefore, the running pressure and circulating flow of a circulating medium are stabilized, and the purpose of controlling the temperature of a mold can be indirectly and stably controlled; and the low-temperature mold temperature controller is high in degree of automation, and is simple and convenient to operate.
Description
technical field [0001] The invention relates to the field of temperature control machinery, in particular to a low-temperature mold temperature machine. Background technique [0002] The mold temperature control machine is called the mold temperature machine for short. It is divided into water circulation and oil circulation. It is mainly used for temperature control of general molds and machinery. It can keep the product in the best state during molding within a certain temperature to ensure the quality of the finished product. Uneven or inappropriate mold temperature will lead to dimensional instability of castings, deformation of ejected castings during production, and defects such as thermal pressure, sticking mold, surface depression, internal shrinkage cavity and hot bubbles. It also affects the production cycle, such as filling time, cooling time and spraying time all produce unstable variables. The life of the mold will also cause thermal cracking of expensive steel...
