Embodiment
It is clearer for the technical solution and the technique effect that reaches that make technical problem that the utility model solves, use,
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, present embodiments provide a kind of injection mold, its generally comprise the part of the upper die of mutual cooperation and
Part of the lower die.Bottom plate 8, square iron 7, lower template 2 and lower mold core, the part of the upper die that part of the lower die includes stacking successively include
Upper mold core, cope plate 1, flow distribution plate 5 and the upper mounted plate 6 stacked successively.
Wherein, the lower surface of upper mold core and the upper surface of lower mold core are provided with multiple cavities, and the cavity of correspondence position coordinates
Forming cavity 21 is formed, each forming cavity 21 is respectively provided with a glue-feeder, and injection raw material is filled into cavity 21 by glue-feeder.
In the present embodiment, Hot Runner System 3 is also equipped with flow distribution plate 5 and cope plate 1, Hot Runner System 3 includes multiple
Hot flow path 31, the area of section of each 31 lower end of hot flow path are gradually reduced type and are corresponded to and one into hot filling nozzle 311, each forming cavity 21
The hot-fluid mouth 311 of a hot flow path 31 connects, i.e., hot-fluid mouth 311 coordinates with the glue-feeder of forming cavity 21 and connects, and each hot flow path is equal
Connected with note cast gate 61.
Injection mold provided in this embodiment can be used for injection molding screw or connecting pin less product in equal volume, when
Injection molding other products are so can be used for, are not limited to small sized product.Below using the product of injection molding as connecting pin 9
Exemplified by describe in detail.
When processing connecting pin 9, the injected plastics material of molten condition is filled by noting cast gate into runner, injected plastics material is successively
Flowed into by multiple hot flow paths 31 in Hot Runner System 3 in corresponding forming cavity 21.Injected plastics material in forming cavity 21
It is connecting pin to be gradually cooled and shaped, and is then molded, part of the lower die moves down, and the hot filling nozzle 311 of hot flow path 31 will be with forming cavity
Product in 21 departs from, as shown in figure 3, since the area of section of hot filling nozzle 311 is small, the connecting pin 9 in forming cavity 21 is with lower die
It during componental movement, will be separated automatically with hot filling nozzle 311, take out connecting pin 9 afterwards.Because Hot Runner System 3 is held as heated, position
The liquid condition of melting is remained in the injected plastics material in hot flow path 31, therefore, during simultaneous manufacturing, hot flow path
Injected plastics material in 31 will not cure, and after die sinking, injection molding machine stops providing injection pressure to Hot Runner System 3, due to hot filling nozzle
311 is smaller, and the injected plastics material in hot flow path 31 will not flow out, and can continue on for molding process next time, Bu Huizao
Into the waste of the injected plastics material in Hot Runner System 3.
Injection mold provided in this embodiment, during connecting pin 9 is processed, will not produce cold waste material, avoid being molded
The waste of material, reduces the production cost of connecting pin 9.Further, since cold waste material is not produced in 9 forming process of connecting pin, into
Type is more stablized, and improves the quality of connecting pin 9, can improve shaping efficiency, shortens the molding cycle of connecting pin 9, reduces
The price of single product.
