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
The invention belongs to a kind of cooling system, be specifically related to the cooling system of a kind of high-temperature resin and high-temperature carbon fiber compression molding die.
Background technology
In process of production, the cooling of mould is one of key factor affecting this type of material product for current high-temperature resin and high-temperature carbon fiber material compression molding die product.Mostly adopt liquid (water) to cool at present, adopt liquid-cooling system normally to carry out liquid cooling to upper and lower shell, core.After formed product, liquid (water) is injected mould water channel, and is flowed out by water channel thus reduce mold temperature, after mould is down to and is needed temperature range, then drain the liquid (water) in mould water channel.
In real process, mould at high temperature uses liquid (water) to lower the temperature, easily make mould modification, and produce a large amount of superheated vapors, the dimensional accuracy of article of manufacture and positional precision is made to be difficult to ensure, and this type of mould needs to be down to very low temperature range, and liquid (water) takes away heat speed comparatively slowly, waits for that mold temperature drops to the chronic of the scope of expectation.After dropping to and needing temperature, mould inside liquid (water) is also not easily drained, and can produce superheated vapor again when mould is heated up again.
Summary of the invention
The object of this invention is to provide a kind of cooling system of mould, it can realize scientifically controlled cooling model time and temperature, reaches the raising ensureing this type of mold performance and production capacity.
The present invention realizes like this, a kind of cooling system of mould, it comprises high-pressure water, compressed air source, and high-pressure water, compressed air source are connected with control cabinet respectively, and high-pressure water is connected with water tank, water tank is connected with control cabinet, control cabinet is connected with flow equalizing valve, and flow equalizing valve is connected with mould, and mould is connected with check valve, check valve is connected with control cabinet, and control cabinet is connected with water tank.
Advantage of the present invention is, the latent heat utilizing water, liquid gas absorbs a large amount of heat in phase transition process, and be aided with namely pressure-air realizes mould fast cooling by taking the water after phase transformation out of, and can temperature-reducing medium in dry clearly cooling duct, and be achieved the control of temperature and reduce the requirement of mold temperature fast, reach and improve die sinking efficiency, increase the object of production capacity.
Accompanying drawing explanation
Fig. 1 is the cooling system structure schematic diagram of a kind of mould provided by the present invention.
In figure: 1 high-pressure water, 2 compressed air sources, 3 control cabinets, 4 flow equalizing valves, 5 moulds, 6 check valves, 7 water tanks.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figure 1, a kind of cooling system of mould comprises high-pressure water 1, compressed air source 2, high-pressure water 1, compressed air source 2 are connected with control cabinet 3 respectively by pipeline, high-pressure water 1 is connected with water tank 7 by pipeline, and water tank 7 is connected with control cabinet 3, and control cabinet 3 is connected with flow equalizing valve 4 by pipeline, flow equalizing valve 4 is connected with mould 5 by pipeline, mould 5 is connected with check valve 6 by pipeline, and check valve 6 is connected with control cabinet 3 by pipeline, and control cabinet 3 is connected with water tank 7 by pipeline.
The present invention adopts normal temperature gas, liquid (water) blending agent is mould cooling.Cooling point three phases is implemented: the first stage, mould 5 temperature higher (boiling point higher than liquid medium), compressed air source 2 under the control of control cabinet 3 by air compressing, and a small amount of water allocated in high-pressure water 1 formed water smoke by flow equalizing valve 4 enter in mould 5 quickly through, carry out fast cooling; Second stage, when mould 5 temperature is middle temperature (boiling point lower than liquid medium), turns off compressed air source 2, strengthens the output in high-pressure water 1, passes through rapidly, utilize liquid to reduce temperature faster in mould 5; Phase III, when mould 5 temperature is low temperature, stop the supply of high-pressure water 1, the gas then compressed air source 2 being provided with full admission amount is by mould 5, and mould 5 inner chamber is dried up, affect to avoid residual water in mould 5 after it heats up and heats up and form superheated vapor to the infringement of mould.
