Cooling system for die

Abstract

The invention specifically relates to a cooling system for a die, which belongs to the field of cooling systems. The cooling system for the die comprises a high pressure water source and a compressed air source, wherein the high pressure water source and the compressed air source are both connected with a control box; the high pressure water source is connected with a water tank; the water tank is connected with the control box; the control box is connected with a current equalizing valve; the current equalizing valve is connected with the die; the die is connected with a non-return valve; the non-return valve is connected with the control box; and the control box is connected with the water tank. The cooling system has the following advantages: latent heat of water is utilized, liquid gas absorbs considerable heat in the process of phase change, and high pressure air is cooperatively used to carry phase-changed water away so as to realize rapid cooling of the die and cleaning of a cooling medium in a cooling channel; thus, requirements for temperature control and rapid reduction of die temperature are met, die-opening efficiency is improved, and production power is enhanced.

Description

technical field [0001] The invention belongs to a cooling system, in particular to a cooling system for high-temperature resin and high-temperature carbon fiber molding dies. Background technique [0002] At present, in the production process of high-temperature resin and high-temperature carbon fiber material molding mold products, the cooling of the mold is one of the key factors affecting such material products. At present, liquid (water) cooling is mostly used, and the liquid cooling system is usually used to liquid-cool the upper and lower shells and cores. After the product is formed, inject liquid (water) into the water channel of the mold, and flow out through the water channel to reduce the temperature of the mold. After the mold drops to the required temperature range, the liquid (water) in the water channel of the mold is drained. [0003] In the actual process, the mold uses liquid (water) to cool down at high temperature, which easily deforms the mold and gener...

Problems solved by technology

[0003] In the actual process, the mold uses liquid (water) to cool down at high temperature, which easily deforms the mold and generates a large amount of superheated steam, making it difficult to guarantee the dimensional accuracy and position accuracy of the produced product, and this type of mold needs to be reduced to a very low level. Temperature range, while the liquid (water) takes away heat slowly, and it takes a long time to wait for the mold temperature to drop to the expected range
