Description
Technical field
The utility model belongs to the Mold Making technical field, relates to the aluminium extracting mold that a kind of computer radiator that is used to extrude high density, high multiple is used specifically, more particularly is a kind of aluminium extruded type master mold that is used for extruding the computer radiator of heronsbill structure.
Background technology
Aluminium extracting mold not only can be in order to extrude articles for daily use such as common aluminium tube, aluminium door and window, also can be in order to extrude higher computer radiator of technology content (radiator fan) and optical measurement body etc.Can there be any technology barrier hardly in the aluminium extracting mold of using in order to daily lifes such as extruded aluminum tubing, aluminium door and window materials for processing, even in order to process the mould that early stage aluminium matter computer radiator is used, because it is not high that the radiating efficiency of early stage computer radiator requires, spacing between the radiating fin is big, (computing formula of multiple is multiple: the width=multiple of radiating fin height/stressed support portion) also little, the force-bearing situation of mould is good, and the pressure in the time of can supporting extruding reaches 120kg/cm
2Can not cause mould in the same old way and reverse mould occur, therefore, make such mould and still can not have technical difficulty.
Raising and sophistication along with CPU (CPU) floating-point operation speed, taking up space less as much as possible and improving under the requirement of radiating efficiency, under the situation in overall volume that can't strengthen computer radiator and space, can only consider to the spacing of dwindling between the radiator fins, increase area of dissipation so that promptly increase density, make it to improve radiating efficiency by increase radiator fins quantity.And, require harsh radiator fins for heat radiation, except dwindling the spacing between the fin, be attended by high multiple requirement toward contact, therefore, having only close and elongated fin is that the high multiple fin of high density could satisfy and occupies the instructions for use that the space is little, radiating efficiency is high, but, as mould, the elongated radiating fin of healing easily subsides because of root structure support force shortcoming heals when extruding, lateral thrust occurs and cause the support portion fracture and then mould is scrapped, thereby the processing of this type of mould has been proposed challenge.To this, it is the method for the intensity of iron plate that the applicant has found the radiating fin that strengthens on the mould, and has applied for patent.Why can cause the fracture in order to the support portion of the radiating fin on the mould that extrudes high density, high multiple computer radiator, reason is that traditional method is in order to control that aluminium flows out the speed of material and the Bearing face that is referred to as the work zone in the custom that end, both sides, the base portion of radiating fin is processed with the moulding function of tool respectively.Yet, make the intensity of radiating fin to ensure just because of the existence of work zone.Therefore, the applicant is that the end points, both sides, base portion with radiating fin forms the inclined plane with Different Slope and promptly come balance aluminium to flow out the material speed with slope variation, abandoned the work zone therefrom, make the intensity of radiating fin be able to ultimate attainment raising, mould is satisfied process high density, the requirement of high multiple computer radiator with being able to volume production.
Yet, along with CPU floating-point operation function so that improve, the heat radiation of desired computer radiator is renderd a service also and is improved thereupon.For example, resemble the computer radiator 5 of heronsbill structure illustrated in figures 1 and 2, this computer radiator 5 belongs to high density, high multiple category, radiator fins 51 is close and elongated, radially, its coefficient of heat conduction is radial to external diffusion via radiator fins 51, so radiating effect is quite desirable.But only the manufacture difficulty of its this class mould is more outstanding, the phenomenon that radiating fin in the welding chamber of master mold ruptures from root often takes place because of extruding force is too high to be distributed in radially, although the slope variation with on the radiating fin that the applicant can be mentioned in front comes the method that balance aluminium flows out the speed of material to be applied on this type of mould, only can reach the effect of alleviation and can not eradicate.To this, can understand more by following explanation.
Fig. 3 is as if that being used in the prior art extrudes all the structure of the master mold 1 of the aluminium extracting mold of the computer radiator 5 of Fig. 1, shape shown in Figure 2, tool welding chamber 11 and the radiating fin that distributes radially 12 that is positioned at 11 rear portions, welding chamber.So be very fragile the service life of the master mold 1 of structure, because suffered pressure source is quite concentrated, aluminium stream shows as plane He Hui (claiming interflow, plane or plane to conflux again), makes whole surface pressurized simultaneously.Because flowing to, aluminium just can extrude (depanning) after welding chamber 11 must fully be filled up, just in the process of filling up, because the rapid increase of pressure, the root 121 of radiating fin 12 is because of being difficult to keep out the pressure that it can bear, when pressure reaches critical that it can bear, just produce fracture, cause scrapping of master mold 1.Through applicant practice and show, the extruding force of computer radiator 5 that extrudes Fig. 1, shape shown in Figure 2 is at 100kg/cm
2About; this occupy high extruding force be difficult to make master mold 1 be positioned at root 121 11 rear portions, welding chamber and radiating fin 12 that arrange radially and resist; perhaps the someone thinks that reducing whole extruding force can protect the root 121 of radiating fin 12 to exempt from fracture; but, merely reduce extruding force and can cause the aluminium material to extrude.Though people discover to some extent, cause radiating fin 12 root 121 fractures because of being the surface in welding chamber 11 simultaneously due to the pressurized, it is right that promptly pressure is too concentrated institute, not seeing so far has concrete conduct.
Summary of the invention
