Problems solved by technology

Cooling molds with chilled water is a common practice to improve production efficiency and meet product manufacturability, but there are certain defects. When controlling cooling, since the mold needs to form a cooling system with multiple cooling channels, and each cooling channel requires The cooling capacity is also different. The temperature and pressure of the chilled water entering the mold in the existing mold cooling water system are the same, and the cooling of the mold is not balanced, resulting in the inability to accurately make the overall temperature of the mold uniform.

Abstract

The invention discloses a mold cooling system and a mold cooling control method. The mold cooling system includes a mold and a water segregator, two or more circulating flow paths are formed between the mold and the water segregator, and cooling media are disposed in the circulating flow paths. Electrical control throttle valves and temperature sensors are disposed on the circulating flow paths, and the temperature sensors are used for monitoring the temperature of the cooling media and sending the collected real-time temperature information to a microcomputer. The microcomputer is connected with stepping motors, and the stepping motors are connected with the electrical control throttle valves; and the microcomputer is used for realizing an opening size of the electrical control throttle valves by controlling the number of revolutions of the stepping motors. According to the mold cooling system and the mold cooling control method, the whole system collects data through the microcomputer and controls the cooling water volume of the corresponding circulating flow paths through the stepping motors, and the cooling balance of the mold is ensured.

Description

technical field [0001] The present disclosure relates to a cooling system, in particular to a mold cooling system and a control method for mold cooling. Background technique [0002] At present, the oil tank and the mold of the known injection molding machine need to be cooled. Since the cooling temperature requirements of these two parts are not the same, the common injection molding manufacturers use two cooling systems for the oil tank cooling and mold cooling of the injection molding machine. The cooling tower supplies water to cool the oil tank of the injection molding machine, and the chilled water of the chiller independently cools the mold of the injection molding machine. Cooling molds with chilled water is a common practice to improve production efficiency and meet product manufacturability, but there are certain defects. When controlling cooling, since the mold needs to form a cooling system with multiple cooling channels, and each cooling channel requires The co...
