Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
In the present invention, in the case where not making opposite explanation, " upper and lower, inner and outer " etc. is included in the orientation in term
Word only represents orientation of the term under normal service condition, or be skilled artisan understands that be commonly called as, and be not construed as
Limitation to the term.
The invention provides a kind of compacting tool set, wherein, the mould includes lower mould and cooperatively formed with the lower mould
The upper mould of die cavity, wherein, as shown in figure 1, be provided with the lower mould at least one raised steady pin 1, the upper mould with
Through hole, and external diameter of the internal diameter more than the steady pin 1 of the through hole, institute are provided with the corresponding position of the steady pin 1
The depth for stating through hole is less than the height of the steady pin 1.
According to above-mentioned technical proposal, the present invention sets the steady pin 1 of projection on lower mould, and in upper mould with the steady pin
Internal diameter is set to be more than the through hole of steady pin external diameter on 1 corresponding position, can be with so that being formed between steady pin 1 and through hole
The other parts placed in the cavity of prefabricated component 4, the die cavity that then will be formed between upper mould and lower mould are filled out using inserts
Fill, so that the inserts wraps prefabricated component 4, obtained product can be taken out after cooling, as shown in Fig. 2 prefabricated
The shapes such as screw thread are processed already inside part 4, therefore, the problem of in the absence of secondary operation, meanwhile, prefabricated component 4 is rigid material
Material, situations such as snaggletooth of the shapes such as screw thread can be also avoided significantly, and then other parts will not be also hindered by material systems such as aluminium alloys
It is standby.
In order to which preferably inserts is poured into, the present invention it is a kind of preferred embodiment in, also set on the lower mould
Material feeding groove 2 is equipped with, is connected between the material feeding groove 2 and the die cavity.So that inserts can be direct by material feeding groove 2
Pour into the die cavity, it is certainly, also possible without material feeding groove 2, but in order to avoid occurring being not easy to pouring into, and directly fill
Entering may be such that inserts does not pour into as needed, inserts occur and fill out the situation to outside mould, and then occur wasting existing
As the problem of, or to add the above-mentioned material feeding groove 2 being connected between die cavity.
A part for the not die cavity of material feeding groove 2, thus upper mould and the material feeding groove 2 need not be included, therefore, in order to avoid because
Material feeding groove 2 in lower mould causes mould to be when lower mould mutually agrees with the skew it is possible that on position, in one kind of the present invention
In the embodiment being more highly preferred to, one end in the material feeding groove 2 close to the die cavity is additionally provided with locating piece 3, and described fixed
