Specific embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
As shown in Figure 1 to Figure 2, charger baby shell the Aluminum-Extruding Die described in the utility model includes upper mold 1, lower die 2, sets
Positioning pin 3, combination close-fitting seam allowance 4 and the fixing piece 5 for connecting upper and lower mould being placed between upper and lower mould, upper mold 1 are provided with height and set
The end face 1a that puts and enter charge level 1b, enter charge level 1b and be located at end face 1a lower sections (being recessed within the 1a of end face), end face 1a and pan feeding
Face 1b forms pressure buffer area, can buffer the pressure that mold is subject to.
Set there are two symmetrical tap hole 6 and separate the shunting bridge 7 of tap hole 6 on charge level 1b is entered, two
6 shape of tap hole is big for intermediate small both sides, makes metal inflow velocity more uniform, and fillet can guide the entrance of aluminium material, mitigates
The extruding force that shunting bridge 7 is subject to.1 center of upper mold is provided with shunting 7 integrally formed mold core 9 of bridge, and 9 surface of mold core is successively
Pan feeding fillet 20, decompression band 15, drainage area 16 and mold core work band 12 are provided with, the section of mold core 9 is at the decompression band 15
In into the shape changed from small to big, 9 section of mold core is at drainage area 16 in shape from large to small.Pan feeding fillet 20 and decompression band
15 when can mitigate metal flow to extruding force caused by mold core 9.7 lower section of shunting bridge is provided with upper mold bonding container 8, tap hole
6 section is to change from small to big horn-like, balanced flow rate of metal and can increase the appearance of upper mold bonding container 8 with drainage area 16
