Abstract
The present invention relates to a direct method of making a forming mold, which comprises the following steps: firstly, making a master mold, and making an edge homoplastically extending along the periphery of a parting surface; using metallurgical powder to fill a mold frame, and close attaching the metallurgical powder to the master mold; then processing the master mold with the metallurgical powder by oil pressure; sintering the master mold with the metallurgical powder; milling the parting surface; opening a mold; finally obtaining the mold by finishing. An upper mold and a lower mold are obtained simultaneously by the direct method, and the method is likewise applicable to molds with simple shapes and complex shapes; in addition, the method with the advantage of simpleness not only reduces mold cost, but also further effectively controls the cost because different metallurgical powder can be selected according to the specific requirements of the service life, application, etc. of molds; therefore, the method can be widely applied to the manufacture of forming molds, die molds and injection molds for covering parts on cars and motorcycles, and the manufacture of other molds for complex parts.
Description
Technical field
The present invention relates to a kind of usefulness and directly get the method that the mode of type is made mould, belong to the technology of die manufacturing field.
Background technology
In the manufacturing cost of product, the cost ratio of sharing mould is very high in general, common general product volume, as 100,000, the ratio of sharing die cost account for product cost about 10%, and amount is more little, and is higher more than regular meeting.Cause the reason of this situation that some is arranged; The one, because traditional diel adopts punching block or pig mold more, though its precision height, life-span are long, the material cost height; The 2nd, for the mold shape complexity, the manual manufacturing is difficult to accurate control, need carry out digital control processing usually, further strengthened manufacturing cost; The 3rd, traditional mould manufacturing all is that upper and lower mould is made respectively, makes complicated.
Summary of the invention
At the prior art above shortcomings, the object of the present invention is to provide a kind of method of direct making forming mold, this method is selected the metallurgical powder material for use, and upper and lower mould directly obtains simultaneously, and cost is low, makes simple.
The present invention realizes according to the following steps:
(1) system master mold: at first get outturn sample and make a master mold, system is during master mold, and selected suitable die joint is made the limit of extending along die joint periphery similar shape simultaneously, and this extension edge is a usefulness of opening upper and lower mould when making things convenient for die sinking along die joint.This extension edge can be reinforced with the high strength frame, and under the enough condition of proof strength Bao Yuehao more.
(2) filling is framed: master mold is put into the framed central authorities of steel fix, and full framed with previously selected metallurgical powder filling, and metallurgical powder and master mold are fitted tightly, do not stay any spaces.
(3) oil pressure: will fill the full framed hydraulic press of putting into and pressurize, the tonnage of hydraulic press choose should consider to suppress tonnage greater than or equal the punching press tonnage that mould will be scheduled to bear at least, so just can guarantee the quality of mould.
(4) sintering: the mould after will pressurizeing is put into the sintering furnace sintering, and temperature is decided according to the selected material of mould.
(5) mill out die joint: take out sintered part, treat its cooling after, redundance on the mill off mould is until the extension edge that exposes die joint.
(6) die sinking: open upper and lower mould along die joint, take out master mold.
(7) finishing: upper and lower mould is carried out conventional finishing process, promptly obtain mould.
Should wait the composition of choosing metallurgical powder according to the scope of application, the life requirements of mould among the present invention.For example: it is low to make the hardness requirement, the iron welding bell tool that life requirements is short, and the available iron based powders is a material, and it is high to make the hardness requirement, and the complicated die of life requirements length, can select cemented carbide powder for use is material.
The advantage of this method is:
1, directly gets type and obtain upper and lower mould simultaneously, mould to simple shape and complexity is all suitable equally, method is simple, has reduced die cost, can be widely used in the mould manufacturing of complex parts such as automobile, motorcycle cap piece shaping mould, compression mod, injection mould.
2, can and specific requirement such as be suitable for according to die life and select different metallurgical powders for use, can further control cost effectively.
Description of drawings
Fig. 1 is for producing the structure chart of door reinforcement (KD spare) diel in the automobile with the inventive method.
The specific embodiment
Embodiment:
Referring to Fig. 1,1 is framed among the figure, the 2nd, and master mold, the 3rd, die joint, the 4th, extension edge.
Produce mould according to the following steps:
1. get the KD spare of Japanese import and make master mold, select die joint, and along periphery system extension edge.If untouched edge own then can be used as extension edge at this point.
2. with the KD spare of Japanese import, put into the steel counterdie of powder filler, and firmly compacting, make powder be full of the following profile of KD spare, pour into above the KD spare with the powder of identical component again, and firmly compacting, make powder be full of the last profile of KD spare.
3. the hydraulic press with 315 tonnages pressurizes to mould, compacting.
4. sintering.
5. taking-up sintered part, treat its cooling after, unnecessary part on the mill off mould is until the extension edge that exposes die joint.
6. open upper and lower mould along die joint, take out master mold.
7. upper and lower mould is carried out conventional finishing process, promptly obtain mould.
Claims (2)
1. the direct method of making forming mold is characterized in that carrying out according to the following steps:
(1) system master mold: select outturn sample system master mold for use, and behind selected die joint, make the limit of extending along die joint periphery similar shape;
(2) fill framed: master mold is put into framed, is filled framedly with the metallurgical powder material, make it to fit tightly with master mold;
(3) oil pressure: will fill full framed putting on the hydraulic press and pressurize, the compacting tonnage of hydraulic press should greater than or to equal mould at least predetermined with the punching press tonnage that bears;
(4) sintering;
(5) mill out die joint: after to be sintered the cooling, mill on the mould redundance until the extension edge that exposes die joint;
(6) die sinking: open upper and lower mould along die joint, take out master mold;
(7) finishing gets mould.
2. method according to claim 1 is characterized in that the extension edge of master mold die joint can be reinforced with the high strength frame, under the enough condition of proof strength, and Bao Yuehao more.
