Abstract
The utility model discloses a mould based on lamination powder compacting forming technology makes, this mould include the body by the metal powder press forming, the hollow cooling water route of this internal formation. The utility model discloses the mould in water route is cooled off along with shape to the built -in complicacy of producing, and in the life -span that not only can improve the mould, the accessible reduces product molding cycle and improves production efficiency the time in addition, but while reduction in production cost.
Description
Technical field
The relevant a kind of mould of this utility model and processing technology thereof, particularly relate to a kind of use lamination powder pressing forming technology to manufacture mould and the manufacture method thereof in built-in complicated conformal cooling water route.
Background technology
Many moulds in use can be in hot environment, such as mould for die casting, be molded and the hot environment such as blowing, it is therefore necessary to by cooling system, the heat of fusing material is taken away.Design a suitable cooling system to be possible not only to extend die life, it is possible to improve production efficiency and shorten formed product cycle time.Conventionally manufactured cooling water channel relies on the method for boring, but, this method makes straight line water route only, can not manufacture the complicated conformal cooling water route of die surface profile.And drill bit when boring long water route, can be broken so that whole mould cannot use.Additionally, due to differ along the distance between mold wall and cooling water channel, cause length cool time, form internal stress and finished product warpage.
Having the design of a kind of cooling water channel to be referred to as conformal cooling system at present, it is defined as the shape of cooling water channel and can fit the profile of die surface.Under this mode, shaped article can cool down quickly and evenly.Comparing traditional cooling system, conformal cooling system can shorten the formed product cycle time of 30-60%.The saving of this time and product geometric correlation.Shorten formed product and can improve integral production ability, the multiple mould of minimizing and workshop spending cycle time.Additionally, compare the mould using tradition cooling system, the die life of built-in conformal cooling system is longer.Then conformal cooling system can be bonded together cooling water channel at two Die and mould plates respectively by Diffusion Welding by traditional processing technique (such as milling, brill, electric spark etc.) two die sheet surface manufactures.This way can only produce the conformal cooling water route of relatively easy geometry, because Diffusion Welding can only composition plane.The conformal cooling water route of complex geometric shapes can be manufactured by direct metal laser sintering (DMLS) technology, but above two technique needs to put into expensive equipment, relatively costly.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of mould manufactured based on lamination powder pressing forming technique.
For reaching above-mentioned purpose, this utility model provides a kind of mould manufactured based on lamination powder pressing forming technique, and this mould includes the body compressing by metal dust, the cooling water channel of this internal formation hollow.
Described cooling water channel is three-dimensional conformal cooling water route.
Described metal dust is steel, ferrum, copper, aluminum pure metal powder material and alloy thereof or tungsten carbide.
This utility model is applicable to manufacture die casting, injection mo(u)lding, blow molding etc. needs the metal die of cooling system.Dynamical cooling system not only can improve the life-span of mould, and can improve production efficiency cycle time by reducing formed product, and mould the most of the present utility model can reduce production cost.

Detailed description of the invention
For ease of method of the present utility model and the effect that reaches there being further understanding, describe in detail as follows in conjunction with accompanying drawing.
Fig. 1 shows that in this utility model, metal dust fills the schematic diagram of die cavity.First filling layer of metal powder 2 in die cavity 1, be a fixing low punch 3 below the metal dust 2 in die cavity 1, this low punch 3 closely cooperates with the inwall of die cavity 1 and supports the bottom of this metal dust.Fig. 2 shows the schematic diagram of the compressing process of this utility model metal dust.It is provided above a upper punch 4 at metal dust 2, upper punch 4 is down pressed, under the upper punch 4 extruding with low punch 3, metal dust 2 molding by high pressure.Fig. 3 shows that Milling Process manufactures the schematic diagram in water route.Upper punch 4 is taken away, the metal dust 2 after compressing utilizes milling cutter 5 processing and manufacturing water route 6.Fig. 4 shows the schematic diagram filling water route with low-melting-point material.With low-melting-point material 7(such as paraffin or other for the wax material of lost wax process) fill before the water route 6 that mills out.Repeat above-mentioned filling out powder, compacting, milling and fill the operation in water route with low-melting-point material, produce required waterway structure layer by layer.Fig. 5 shows the crude product structural representation of the mould that can set conformal water route in making.Die cavity 1 and low punch 3 are taken away, whole crude product mould is heated, make internal low-melting-point material 7 flow out, the crude product mould in formation built-in complicated conformal cooling water route as shown in Figure 6, just can obtain hollow cooling water channel 8 through above-mentioned operation.This crude product mould carries out high temperature sintering again, and mould overall dimensions the most accurately can be obtained by traditional processing technique (such as milling, electric spark, sanding and polishing processing etc.).
In this utility model, utilize the built-in complicated cooling water channel of the compressing made mould of lamination metal dust, as shown in Figure 6, the mould that this utility model makes has the body compressing by metal dust 2, the cooling water channel 8 of this internal formation hollow, this cooling water channel 8 is three-dimensional conformal cooling water route, and is arranged to according to demand and the trend of body profile same shape.Heat in mould may pass through cooling water channel wall and reaches coolant and be then pulled away.This utility model is applicable to manufacture die casting, injection mo(u)lding, blow molding etc. needs the metal die of cooling system.Dynamical cooling system not only can improve the life-span of mould, and can improve production efficiency cycle time by reducing formed product.The metal dust of this utility model mould can be steel, ferrum, copper, aluminum pure metal powder material and alloy or tungsten carbide etc..
Contrast is based on Diffusion Welding and the method for DMLS, and this utility model, merely with lamination powder pressing forming and other auxiliary equipment, has relatively low cost of investment.Additionally, the size of mould does not has any restriction.Cooling water channel can carry out milling by demand and manufacture, and complicated three-dimensional conformal cooling waterway structure just can easily realize, and considerably increases design space.Made the mould of built-in complicated cooling water channel by method of the present utility model, ratio is short with other existing methodical time of delivery, makes user obtain more economic well-being of workers and staff.
Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only detailed description of the invention of the present utility model; it is not used to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, within should be included in protection domain of the present utility model.
