Abstract

The invention relates to a novel mold temperature controller. A heater and a media pump are arranged in the mold temperature controller. The media pump is connected with the heater. The heater is connected with a mold inlet. A mold outlet is connected with an inlet of the media pump, and a temperature detecting structure is arranged between the heater and the mold inlet. Pressure detecting devices are installed at the inlet and an outlet of the media pump correspondingly. A booster pump outlet is further formed in the position, away from the corresponding pressure detecting device, of the inlet of the media pump. A booster pump inlet is connected with cooling water. By adoption of the novel mold temperature controller provided by the invention, a booster pump can conduct supercharging operation according to a supercharging pressure value corresponding to a set temperature value through a saturated vapor pressure relation; when the pressure intensity is sufficient, the booster pump stops supercharging operation, and the pressure intensity in a system is kept constant; when the pressure intensity of the system is decreased, the booster pump is started again, the probability of water leakage is decreased, the service life is prolonged, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of mold temperature controllers, in particular to a novel mold temperature controller and a control method for matching boost pressure and temperature. Background technique [0002] The high temperature type (maximum working temperature > 120°C) water circulation mold temperature regulator in the rubber and plastic industry must have a booster pump to meet the use under high temperature conditions due to the limited cooling water pressure provided by the customer (generally 0.2MPa). However, the boost pressure of high-temperature mold temperature controllers currently on the market is set according to the pressure value required by the highest temperature. For example, the boost pressure required by a 160°C mold temperature controller is about 0.62MPa, so the set value It is 0.62MPa, and the supercharging pressure is always maintained at this value through the work of the booster pump. However, this kind...
