Description
Technical field
The utility model relates to the casting core assembling technology, particularly relates to a kind of water cooling plant of controlling the multiple-core casting cooling velocity.
Background technology
Multiple-core casting technology has advantages such as casting dimension is accurate, surface quality good, system sand is convenient to recycle, and is widely used.But to be the foundry goods cooling velocity slow and be not easy control for the shortcoming that multiple-core casting is compared with permanent mold casting or tide mould sand, is difficult to realize that consecutive solidification or part are cold soon, is difficult to guarantee the inherent compactness of local thick and large casting.Under the situation about having, even use cumbersome chill can not arrive ideal results.This shortcoming makes multiple-core casting technology to quality requirement height, complex-shaped and foundry goods local thermal center certain limitation be arranged, as the aluminium alloy cylinder cylinder head casting of automobile industry.
Multiple-core casting all adopts the nature cooling means to realize molten metal solidifying in sand mold at present, but because the sand mold poor thermal conductivity, accumulation of heat is little and self run into molten metal also generates heat, make that the foundry goods cooling velocity is slow, and be not easy to control, be difficult to realize that consecutive solidification or part are cold soon, be difficult to guarantee the inherent compactness of local thick and large casting, under the situation about having, even use cumbersome chill can not arrive ideal results.
Summary of the invention
The purpose of this utility model provides a kind of water cooling plant of controlling the multiple-core casting cooling velocity.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of water cooling plant of controlling the multiple-core casting cooling velocity, it comprises frame, is arranged on the bosh that is used for storing water on the described frame, the top of described bosh is provided with lowering or hoisting gear, and described lowering or hoisting gear can be brought sand mold in the described bosh into and cool off.
Preferably, described lowering or hoisting gear comprises framework, drives the driver part of described framework lifting, and sand mold is placed in the described framework and enters in the described bosh.
Further preferably, described frame is provided with sand mold and sends into passage, sends passage, the described both sides that are arranged on described bosh of sending into passage, sending passage, sand mold can be delivered in the described framework from the described passage of sending into, and can deliver to the described passage of sending in described framework.
Preferably, the sand mold bottom is provided with the dolly that it is transported.
Because technique scheme is used, the utility model compared with prior art has following advantage and effect:
The utility model utilizes external physical cooling way-water-cooled, and device is controlled the cooling velocity of multiple-core casting diverse location, realize cooling fast and local cooling fast, guarantee the inherent quality of foundry goods, make multiple-core casting technology can be used for produce the foundry goods of quality requirement height, complex-shaped and local thermal center in enormous quantities, as the aluminium alloy cylinder cylinder cap of automobile industry etc.

Accompanying drawing 1 is the schematic diagram of water cooling plant in the utility model;
Accompanying drawing 2 arranges the schematic diagram of cooling duct for sand mold in the utility model;
Accompanying drawing 3 is in the interior schematic diagram of water cooling plant for the cooling duct sand mold is set in the utility model.
Wherein: 1, frame; 10, send into passage; 11, send passage; 2, bosh; 3, lowering or hoisting gear; 30, framework; 31, driver part; 4, sand mold; 40, cooling duct; 5, dolly; 6, the local thick large part of foundry goods.
The specific embodiment
Below in conjunction with accompanying drawing and case study on implementation the utility model is further described:
A kind of control method of multiple-core casting cooling velocity in sand mold 4, is put into immediately water with the sand mold 4 after the cast with pouring metal melt, makes the foundry goods of sand mold 4 inside cool off in water, solidify.Water is by micro-pore between the sand grains of sand mold 4 wall thickness, etch core assembly mold cavity surface, behind the contact high-temperature liquid metal, produce carburation by evaporation, the medium of vaporization directly contacts with alloy solution, thereby takes away crystallization latent heat by high cooling velocity, passes through heat exchange action, the casting solidification cooling velocity is accelerated, and foundry goods obtains thinner grain structure.Like this, take away the heat of sand mold 4 and foundry goods bottom by the heat exchange action of water logging erosion core assembly surface and carburation by evaporation, form temperature field from bottom to top, reach the purpose of foundry goods consecutive solidification.According to the difference that casting structure, material and inherent tissue require, temperature and the underwater penetration that can regulate water are very easy to control, and realize automated production.
As shown in Figure 2: the position of the local thick big thermal center of corresponding foundry goods is provided with cooling duct 40 on the sand mold 4, after sand mold 4 after the cast is put into water, water can enter in the cooling duct 40, and to accelerate the cooling of foundry goods part, offering of cooling duct 40 guarantees that sand mold 4 interior molten metals can not spill.In addition, also can reduce the thickness of the local thick big heat energy-saving position of corresponding foundry goods on the sand mold 4.
Above-mentioned control method can be used separately can be in conjunction with using simultaneously.
A kind of water cooling plant of realizing said method as shown in Figure 1: it comprises frame 1, is arranged on the bosh 2 that is used for storing water on the frame 1, the top of bosh 2 is provided with lowering or hoisting gear 3, and lowering or hoisting gear 3 can be brought sand mold 4 in the bosh 2 into and cool off.Specifically:
Lowering or hoisting gear 3 comprises the driver part 31 of framework 30, Drive frame 30 liftings, and sand mold 4 is placed in the framework 30 and enters in the bosh 2.
In addition, sand mold 4 bottoms are provided with its dolly that transports 5.
Below the concrete process of utilizing water cooling plant to realize said method of setting forth:
Pouring metal melt is placed on the sand mold 4 after the cast on the dolly 5 in sand mold 4, carries to bosh 2 by sending into path 10; Framework 30 rises to sending into path 10 under the effect of driver part 31 and flushes, and dolly 5 drives sand mold 4 and enters in the framework 30; Framework 30 drops in the bosh 2 under the effect of driver part 31, cools off, and the underwater penetration of sand mold 4 is controlled according to the difference that casting structure, material and inherent tissue require; After finishing cooling, framework 30 rises under the effect of driver part 31 with sending passage 11 and flushes, and dolly 5 drives sand mold 4 and leaves framework 30, transfer out from sending passage 11, thus the production of realization automation.
As shown in Figure 3: also the sand mold 4 that is provided with the cooling duct can be carried out water-cooled, accelerate the cooling curing of inner foundry goods.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
