Description

A kind of cooling water channel structure of aluminium alloy knuckle mould

Technical field

This utility model is related to a kind of cooling water channel structure of aluminium alloy knuckle mould.

Background technology

In Design of Dies according to the wall thickness and volume of product determining the following design parameter of cooling water channel：Cooling duct Position and size, the length in duct, the species in duct, the configuration in duct and be connected, and cooling water flow rate and heat biography Property.Using when, on the one hand melting metal injection mold cavity in, discharge substantial amounts of heat within the extremely short time Amount, promotes the temperature of mould to improve；On the other hand, mould carries out heat transfer by the mode of conduction, radiation and convection current.Wherein Partial heat is absorbed including the air blowing spraying to mould and cooling water channel, decline mold temperature.After a period of time, upper In the presence of stating the two, temperature reaches an equilibrium point, mould is in a certain temperature range, the temperature of this equilibrium point Control is extremely important to steady production.Mold temperature can also affect product dimensional accuracy, reconcile mould temperature, reduce product molding shrinkage The fluctuation of rate, improves product dimensional accuracy；The temperature can be because the mould temperature difference be big simultaneously, and product shrinks uneven, buckling deformation.Separately Outward, Ruo Mowen is low, and article surface roughness is improved, and is also easy to produce the defects such as cold shut, misrun.It is, casting quality and production Rate depends greatly on mold hot control ability.That cooling water channel cools down forming part surface is uniform, and mould is everywhere The temperature difference is little；Cost-effective cool time is maintained, just using strong cold at reply product heavy wall.Cool time needed for product Increase with its wall thickness and rapidly increase.

Utility model content

In view of the above problems, the purpose of this utility model is to provide a kind of mold temperature control to stablize, and forming part Surface cools down the cooling water channel structure of uniform aluminium alloy knuckle mould.

For achieving the above object, the cooling water channel structure of a kind of aluminium alloy knuckle mould that this utility model is provided, its In, the import of cover half water route and the outlet of cover half water route that the one side of fixed mold is provided with are included in, in the another side of fixed mold On the cold water inlet in cover half face that is sequentially provided with, the cold outlet in cover half face, cover half pour the cold water inlet of mouth line, cover half pour mouth line it is cold go out The mouth of a river, the cold water inlet of cover half material handle line, the cold outlet of cover half material handle line, the cold Inlet and outlet water crossing of cover half point, in the side of moving mold Dynamic model water route import that face is provided with and the outlet of dynamic model water route, the dynamic model face being sequentially provided with the another side of moving mold it is cold enter The mouth of a river, the cold outlet in dynamic model face, dynamic model pour the cold water inlet of mouth line, dynamic model pour the cold outlet of mouth line, the cold water inlet of dynamic model material handle line, The cold outlet of dynamic model material handle line, the cold Inlet and outlet water crossing of dynamic model point.Multiple shuntings are respectively arranged with pipeline in fixed half and moving half Mouthful.

The beneficial effects of the utility model are stablized with mold temperature control, and the uniform effect of forming part surface cooling Really.As each intake-outlet reasonable design on dynamic model and cover half goes out the cooling system of mould, mould is solved well Cooling problem, make the operating temperature of mould 150 --- between 270 DEG C, provide guarantee for steady production, it is ensured that mould Within the temperature range of being in relative stable equilibrium, so that product is readily formed, and prevents and reduce the deformation of product and mould and ask Topic, improves die life.Realize mold temperature control stable, and forming part surface cools down uniform effect.

Specific embodiment

Below in conjunction with the accompanying drawings utility model is described in further detail.

As shown in figures 1-8, a kind of cooling water channel structure of aluminium alloy knuckle mould, is included in the one side of fixed mold 01 The cover half water route import 11 being provided with and cover half water route outlet 12, the cover half face being sequentially provided with the another side of fixed mold 01 Cold water inlet 13, the cold outlet 14, cover half in cover half face pour the cold water inlet 15, cover half of mouth line and pour the cold outlet 16 of mouth line, cover half material The cold Inlet and outlet water crossing 19 of cold outlet 18, the cover half point of the cold water inlet 17 of handle line, cover half material handle line, on the one side of moving mold 20 The dynamic model water route import 21 being provided with and dynamic model water route outlet 22, the dynamic model face being sequentially provided with the another side of moving mold 20 is cold Water inlet 23, the cold outlet 24, dynamic model in dynamic model face pour the cold water inlet 25, dynamic model of mouth line and pour the cold outlet 26 of mouth line, dynamic model material handle The cold Inlet and outlet water crossing of cold outlet 28, the dynamic model point of the cold water inlet 27 of line, dynamic model material handle line 29.Divide on pipeline in fixed half and moving half Multiple diffluence pass are not provided with.Each point of cooling water channel adopts tandem with coupling for main cooling water road, and both cooling water was from cover half water Road import 11 and dynamic model water route import 21 are flowed into, and are separated into some branches, then import cover half water route outlet 12 or dynamic model water route Outlet 22 is discharged；And the cross-sectional area of import trunk water channel Φ D is made more than the cross-sectional area sum of each branch road Φ d.Cooling water hole Minimum distance away from die cavity is 25mm, and too near then inhomogeneous cooling is even, and too remote then cooling effectiveness is low；The a diameter of Φ of cooling water hole 14mm.Cooling water channel is from Mo Wengao field flow orientation mould temperature low areas；To prevent cooling water channel leak, using resistant to elevated temperatures silicone rubber As potted component.

During extrusion casint, mold temperature can be raised with the prolongation of working time, do not having the situation of cooling water Under, up to more than 380 DEG C of mould local temperature causes mould mucosa serious, and mould deforms, and affects part accuracy, accelerates Mould Under Thermal Fatigue Damage；Amount of heat is delivered on equipment simultaneously, also can acceleration equipment damage；As mold temperature is too high, make Part rate of cooling is too slow, causes coarse grains, and performance is reduced, while also reducing production efficiency.So implement cooling to mould being It is very important.In the course of the work, when mould is from equilibrium temperature (about 220 DEG C), quit work this mould 8 minutes mold temperatures Less than 60 DEG C will be dropped to, cooling effect is very good.

Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of design being created without departing from this utility model, can also make some deformations and improvement, these belong to practical new The protection domain of type.
