Description
Technical field
The utility model relates to a kind of cooling device, especially a kind of gas-vapor mix cooling device of casting mould.
Background technology
Low pressure casting is meant molten metal solution by pressure effect filling die cavity and form the method for foundry goods by crystallization and freezing in die cavity.Because used pressure is lower, so be called low pressure casting.Its technical process is to feed dry compressed air in the crucible (or hermetically sealed can) of sealing, molten metal rises along stalk under the effect of gas pressure, enters die cavity reposefully by cast gate, keep the gas pressure on the liquid level in the crucible, till foundry goods solidifies fully.Remove the gas pressure on the liquid level then, make that not solidified molten metal flows back to crucible in the stalk, again open form and release foundry goods.
The advantage of low pressure casting uniqueness shows the following aspects:
1, to fill type more steady for liquid metals;
2, casting forming is good, helps forming the foundry goods of clear-cut, any surface finish, and is more favourable for the shaping of large thin wall casting;
3, foundry goods dense structure, the mechanical performance height;
4, improved the technology recovery rate of molten metal, do not needed rising head generally speaking, the recovery rate of molten metal is improved greatly, recovery rate generally can reach 90%.
In addition, working condition is good; Equipment is simple, easily realizes mechanization and automation, also is the outstanding advantage of low pressure casting.
Liquid metals feeding foundry goods from bottom to up under pressure when making full use of low pressure casting, when carrying out technological design, should consider to make foundry goods to solidify earlier away from the position of cast gate, allow the cast gate final set, make foundry goods in process of setting, obtain feeding, realize consecutive solidification by cast gate.The following measure of normal employing:
1, cast gate is located at the heavy wall position of foundry goods, and makes the thin-walled position away from cast gate; This measure is owing to be subjected to the influence of product design bigger, and a lot of products can't adopt.
2, adjust casting section thickness with allowance, to regulate the directional solidification of foundry goods; This measure increases the use amount of metallic solution owing to increase the surplus of blank, also increases the process time of mach process time and casting, so also do not advise generally speaking adopting.
3, change the cooling condition of foundry goods.This measure is that cost is minimum, also is the best scheme of effect.
The cooling condition of general foundry goods has water-cooled and air-cooled:
Water cooling is the type of cooling that most of moulds adopt, but its shortcoming is also arranged: require seal for pipe joints to get well, the upper and lower conduit road must be unobstructed, and is bigger to the waste of water resource; When chilling temperature surpasses 100 ℃, easily produce vapour explosion.Advantage is that thermal capacitance is bigger, can realize fast cooling.
The present aqueous cold plate that uses of water cooling is connected by bolt with mould and is fitted in the surface that mould need cool off, its shortcoming: aqueous cold plate is yielding not tight with the mould applying, causes cooling effect not good; Water contact aqueous cold plate does not directly contact with mould, influences cooling effect; Prevent to reveal owing to need seal water channel, the position is set on mould limitation.
Air cooling is a kind of more satisfactory cooling means, with water-cooled antithesis, it does not need tight seal for pipe joints, there is not the wasting of resources, can be higher than 100 ℃ mould by chilling temperature, can determine the speed of cooling by the flow of gas, and the source is succinct convenient, has the workshop of certain scale can both obtain source of the gas eaily.But air-cooled because the thermal capacitance of wind is less, and cooling velocity and effect can't satisfy the effect of quick cooling, and cooling cost is big more a lot of than water-cooled.
The air cooler that air cooling is now used directly is blown into pressure-air to reach the effect of mold cools down, shortcoming to living the position that mould need cool off by forced air cooled tube: because the specific heat capacity of gas is lower, can't reach desirable cooling velocity and cooling effect.The cycle of product casting is longer.
Two kinds of types of cooling all have pluses and minuses separately, but all can't obtain perfect results by this dual mode.
The utility model content
The technical assignment that the utility model proposes is to make full use of the fast advantage of water cooling cooling velocity, and the advantage of utilizing air cooling not need tight seal for pipe joints to be provided with in mould easily simultaneously provides a kind of casting mould gas-vapor mix cooling device.For this reason, the utility model is by the following technical solutions:
Casting mould gas-vapor mix cooling device comprises cooling tracheae and cooling water pipe, it is characterized in that: have the injection arm on the described cooling tracheae, have the water arm that is communicated with described injection arm on the described cooling water pipe.
As preferably, described water arm is with to spray arm quantity identical and be communicated with one by one.
As preferably, be connected an interface respectively on described cooling tracheae and the cooling water pipe.
Be connected with solenoid electric valve respectively in the import of described cooling tracheae and cooling water pipe.
The beneficial effects of the utility model are:
1, takes into account the advantage of water cooling, air cooling two kinds of types of cooling, reached better cooling effect.
2. by this utility model, act on cooling water on the mould and be atomized and be water smoke, can not form current after the cooling, influence mould and equipment.
Do not need to be provided with the aqueous cold plate that prevents that cooling water from revealing when 3, working, be easy to be provided with.
4, cooling water, gas can directly contact die surface, cooling effectiveness height.
Description of drawings
Fig. 1 overlooks view for the utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view Amplified image.
The number in the figure explanation: 1-cools off tracheae, the 2-cooling water pipe, and 3-sprays arm, 4-water arm, 5-water inlet, the import of 6-gas.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further.
, casting mould gas-vapor mix cooling device comprises cooling tracheae 1 and cooling water pipe 2 as shown in Figure 1, 2, has the arm 3 of injection on the cooling tracheae 1, has on the cooling water pipe 2 to be communicated with the water arm 4 that sprays arm 3.And water arm 4 is identical with injection arm 3 quantity and connection one by one.Cooling tracheae 1 and cooling water pipe 2 are connected a gas import 6, water inlet 5 respectively on cooling tracheae 1 and the cooling water pipe 2 in the form of a ring, are connected with solenoid electric valve respectively on gas import 6, the water inlet 5.
Can control in the following manner during concrete the cooling: the mould matched moulds, fill type, unlatching cooling steam stove sprays to the surface that mould need cool off to cooling tracheae air feed by spraying arm after filling type, open subsequently that cooling water channel supplies water to cooling water pipe and enter to spray and spray to the surface that mould need cool off after arm is atomized through the water arm, close cooling water channel, cooling gas circuit more successively, final product die sinking pickup.Leng Que position as required, described injection arm can bend the position towards needs.
The utility model sprays into die surface with entering after the water that cools off point atomizes by pressure-air by the control of solenoid electric valve, realizes cooling fast, realizes by the control to cooling water cool time.Therebetween, pressure-air has two effects:
1, sprays by pressure-air, make the cooling water atomizing, prevent from cooling water flow out of mould influence casting;
2, spray the cooling that realizes mould by air.
By two effects of pressure-air, make the utility model work the time take into account the advantage of water cooling, two kinds of types of cooling of air cooling, reach better cooling effect; Do not need during work closely to contact mould, be easy to be provided with; Cooling water, gas can directly contact die surface, cooling effectiveness height.
