Specific embodiment
As shown in Figure 1 and Figure 2, in a kind of injection mould micro metal piece fixed structure, including upper mold 10, metal blade unit
20 and lower die 30；Metal blade unit 20 is made of the sheet metal body 21 of left part and the support plate 22 of right part；The side wall of lower die 30
It is provided with a pair of symmetrical guide and limit column 31；The upper surface of the side wall of lower die 30 forms the side cooperated with support plate 22
The limiting slot of shape；Guide and limit column 31 is located in the limiting slot of lower die 30；Support plate 22 can be set in a pair of of guiding from top to bottom
On limited post 31；The upper plate 11 of elastic lifting is formed on the inner sidewall of upper mold 10；Liter is formed on the inner sidewall of lower die 30
The cutter head 34 of setting drops；Upper plate 11 is located at the surface of cutter head 34；When metal blade unit 20 is placed on lower die 30
Limiting slot in when, sheet metal body 21 is located in the forming cavity of lower die 30,34 face sheet metal body 21 of cutter head and branch
The junction of fagging 22.
As shown in Figure 1, incisal guide is to the upper end of limited post 31 more than lower die 30；The lower end surface of upper mold 10 is formed to be limited with guiding
The escape groove 100 of position 31 upper end of column cooperation.
Lifting groove 101 is formed on the inner sidewall of upper mold 10 as shown in Figure 1, cutting；The lifting of upper plate 11 is arranged in lifting groove
In 101；Pressure spring 12 is provided in lifting groove 101；The upper side wall upper and lower end that the upper end of pressure spring 12 is fixed on lifting groove 101 is fixed
On the upper surface of upper plate 11.
Down-set thimble lifting groove is formed on the bottom surface of the limiting slot of mould 30 as shown in Figure 1, cutting；Thimble lifting
The left side wall of slot forms perforative connecting plate lifting groove 300 to the left；Lifting is provided with thimble 32 in thimble lifting groove；Thimble 32
Left side form with connecting plate lifting groove 300 cooperate connecting plate 33；The left end of connecting plate 33 is vertically fixed on cutter head
On 34；Connecting plate 33 is set on guide and limit column 31.
As shown in Figure 1, cutter head 34 is alloy cutter head.
The fixed structure working principle of micro metal piece:
Die opening state is placed on metal blade unit 20 in the limiting slot of lower die 30, under sheet metal body 21 is located at this time
In the forming cavity of mould 30；Then upper mold 10 and lower die 30 mold, and upper mold 10 and lower die 30 compress support plate 22 at this time, then carry out
Injection molding sheet metal body 21 is embedded in injection-molded work, and after the completion, upper mold 10 rises, and upper plate 11 is still resisted against metal at this time
On blade unit 20, then thimble 32 rises, i.e., cutter head 34 rises, in the interaction of cutter head 34 and upper plate 11
Under, sheet metal body 21 and support plate 22 separate, and complete die sinking as upper mold 10 continues to rise, injection-molded work is in remaining thimble
It is ejected under the action of (not shown), support plate 22 leaves the upper surface of lower die 30 under the action of thimble 32.
The above content is only better embodiment of the invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
