Therefore, the water channel of the mold needs to be descaled. Generally, the descaling agent is poured into the water storage cooling tank, so that it passes through the water channel in a circular flow, and the dissolved impurities will precipitate at the bottom of the water storage cooling tank. Due to the descaling agent It has a certain corrosion effect on molds, water pipes and sealing rings. Therefore, after the descaling process is over, it is necessary to replace the liquid in the water storage cooling tank and use new cooling water to flush the water pipes and waterways to prevent the residue of the descaling agent. This process requires the machine tool to be shut down, which will affect the normal production activities of the enterprise

Abstract
The invention relates to die stamping technology, in particular to a die cooling system and cleaning method, comprising an ECU controller (1), a water storage cooling tank (2), a normally open electromagnetic valve (3), a cleaning water pump (4), an outlet electromagnetic Valve (5), pressure sensor (6), outlet temperature sensor (7), bellows (8), mold (9), water channel (10), inlet temperature sensor (12), inlet solenoid valve (13), pressure accumulator Pressure sensor (14), pressure accumulator (15), water pump, water pipe one (18), water pipe two, one end of water pipe one (18) communicates with the water storage cooling tank (2) and passes through the normally open solenoid valve (3) It is connected in parallel with the cleaning water pump (4), and the other end communicates with the inlet of the water channel. A water channel in the shape of a coil is arranged in the mold, and the outlet of the water channel communicates with one end of the water pipe two, and the other end of the water pipe two is connected with the water storage The cooling tank is connected, and the first water pipe is connected in series with a pressure accumulator, an inlet solenoid valve and an inlet temperature sensor.
Description
technical field [0001] The invention relates to die stamping technology, in particular to a die cooling system and cleaning method. Background technique [0002] In the prior art, in the hot stamping process of metal products, such as automobile anti-collision beams, since the blank before stamping is heated to a set temperature, it is then placed in a pair of dies of the stamping machine, and the Pressure is applied to plastically deform the blank to obtain the desired shape of the metal product. The strength and strain resistance of stamped metal products are improved. In the stamping production process, due to the high temperature of the blank, the heat exchange with the mold during the continuous production process will cause the temperature of the mold to exceed the normal value, deform the mold and affect the shape of the stamping part, and even directly damage the mold. Therefore, in the existing hot stamping process, a water channel is generally designed in the mol...
