Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the nouns of locality be included in term such as " upper and lower, interior and outer " only represents the orientation of this term under normal service condition, or being commonly called as those skilled in the art's understanding, and should not be considered as the restriction to this term.
The invention provides a kind of compacting tool set, wherein, described mould comprises counterdie and coordinates with described counterdie the patrix being formed with die cavity, wherein, as shown in Figure 1, described counterdie is provided with the steady pin 1 of at least one projection, position corresponding with described steady pin 1 in described patrix is provided with through hole, and the internal diameter of described through hole is greater than the external diameter of described steady pin 1, the degree of depth of described through hole is less than the height of described steady pin 1.
According to technique scheme, the present invention arranges protruding steady pin 1 on counterdie, and position corresponding with this steady pin 1 in patrix is arranged the through hole that internal diameter is greater than steady pin external diameter, thus make between steady pin 1 and through hole, to form the cavity can placing prefabricated component 4, then inserts is adopted to fill other parts in the die cavity formed between patrix and counterdie, thus make this inserts wrap prefabricated component 4, obtained product can be taken out after cooling, as shown in Figure 2, the shapes such as screw thread process by prefabricated component 4 inside already, therefore, there is not the problem of secondary operations, simultaneously, prefabricated component 4 is rigid material, also the situations such as the snaggletooth of the shapes such as screw thread can greatly be avoided, and then other parts also can not be hindered to be prepared by materials such as aluminium alloys.
