Abstract
The utility model is related to a kind of powder injection-molded mobile fingerprint decoration semi-finished product, including framework and is arranged on the installation portion that base of frame two ends are used to be installed to framework on mobile phone, it is characterised in that the connecting portion of relative two frames also including connection framework；The centre position of the connecting portion is provided with spot pouring mouth.Two opposite side of fingerprint decoration are connected by the utility model, solve the problem of mold filling is difficult, reduce the sintering warpage of product, it is ensured that product design and dimensional accuracy, reduce shaping difficulty, improve the yields of product, are adapted to batch production.Meanwhile, connecting portion can be cut before sintering to be removed and recycles.
Description
Technical field
The utility model is related to mobile device accessory, and in particular to a kind of powder injection-molded mobile fingerprint decoration half
Finished product.
Background technology
Metal Injection Molding is mutually to tie modern plastics injection molding technology with traditional PM technique
A complicated metallic element New Machining Technology formed by conjunction, is also one and cuts less or without cutting powder metallurgy near-net-shape
Technology.Decoration on mobile fingerprint identification module is typically all to be manufactured by injection molding technology.This kind of frame of decoration
The part of structure, because border thickness and width size is smaller, is difficult to be full of mould, simultaneously because cast gate using side runner charging
Locate the uneven and stress concentration of density, product is easily deformed during sintering.
The content of the invention
In order to solve the above problems, the utility model provides a kind of powder injection-molded mobile fingerprint for being easy to mold filling
Decoration semi-finished product.
The utility model is realized using following scheme：
A kind of powder injection-molded mobile fingerprint decoration semi-finished product, including framework are used with base of frame two ends are arranged on
In installation portion framework being installed on mobile phone, include the connecting portion of relative two frames of connection framework；The connecting portion
Centre position is provided with spot pouring mouth.
Further, the connecting portion is cuboid.
Further, the width of the cuboid is 0.7~10mm, and thickness is 0.2~0.25mm.
Further, the spot pouring mouth is circle, a diameter of 1.4~2.5mm.
Contrast prior art, a kind of powder injection-molded mobile fingerprint decoration semi-finished product tool that the utility model is provided
Have the advantages that:
Two opposite side of fingerprint decoration are connected by the utility model, solve the problem of mold filling is difficult, reduce production
The sintering warpage of product, it is ensured that product design and dimensional accuracy, reduces shaping difficulty, improves the yields of product, is adapted to
Batch production.Meanwhile, connecting portion can be cut before sintering to be removed and recycles.
Brief description of the drawings
Fig. 1 stands for a kind of powder injection-molded embodiment of mobile fingerprint decoration semi-finished product one that the utility model is provided
Body structural representation.
Fig. 2 is that the present embodiment has cut off the schematic diagram after connecting portion.
Embodiment
For ease of skilled artisan understands that the utility model, below in conjunction with specific embodiments and the drawings to this practicality
It is new to be described in further detail.
Referring to figs. 1 to 2, a kind of powder injection-molded mobile fingerprint decoration semi-finished product that the utility model is provided include
Framework 1 and it is arranged on the bottom two ends of framework 1 and is used to being installed to framework into installation portion 2 on mobile phone.In two relative frames of framework 1
Between set one have connection two frames connecting portion 3.The width that is shaped as of connecting portion 3 is 8mm, and thickness is the rectangular of 0.22mm
Body.In the centre position of connecting portion 3, a spot pouring mouth 4 is provided with.Spot pouring mouth 4 is circle, a diameter of 2mm.In mobile fingerprint decoration
In the production of part, the position of connecting portion 3 in mould can be used as the runner in process of injection molding, mould injection metal powder
The opening at end is corresponding with the position of connecting portion spot pouring mouth, in injection process, and metal dust is after spot pouring mouth injection along even
Socket part is diverted at the framework border of both sides, is progressively filled up mould, and mold filling process simplicity is smooth.Connecting portion passes through mould and zero
Part together produces completion, and material is consistent and shrinkage factor is consistent, and flow is short when injecting, blank pressure loss in injection process
It is few, therefore the density of product is also consistent, mostly only occurs in connection the problems such as black line, current mark, Density inhomogeneity formed by
Portion, so as to be deformed when effectively preventing mobile fingerprint decoration from sintering, advantageously ensures that mobile fingerprint decoration profile and outer
Shape dimensional accuracy.
It is removed from the molds, can be carried out after connecting portion is removed with laser cutting after mobile fingerprint decoration injection moulding
Sintering, and the material of the connecting portion cut away can be reclaimed and recycled.
Although being to combine embodiments above to carry out to description of the present utility model, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, be obvious.Therefore, it is all such
Substitute, improvement and change are included in scope of the appended claims.
