Abstract
The utility model is related to a kind of powder injection-molded handset mounting semi-finished product, the handset mounting being made using the handset mounting semi-finished product can be fixed in a mobile phone shell body, parts for fixing mobile phone, the handset mounting semi-finished product include rack body, and the multiple support columns being arranged on rack body the same face；The rack body is provided with the surface irregularity of support column, including multiple step surfaces；The multiple support column is on different step surfaces, and support column upper surface and rack body highest step surface are in the same plane.The utility model is collectively forming a highly consistent supporting surface by the step surface of support column and rack body, when effectively improving handset mounting sintering putting problem and therefore caused by occur in sintering process bend, collapse, ftractureing etc. and deform, it ensure that product design and appearance and size precision, so as to improve yields, and process is simple, it is adapted to batch production.
Description
Technical field
The utility model is related to Metal Injection Molding field, and in particular to a kind of powder injection-molded mobile phone
Support semi-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.In high-temperature sintering process, product is due to gravity, frictional force, and certain deformation often occurs for the reason such as internal stress, especially
After removing binding agent, product is very fragile.Especially similar handset mounting product, profile is larger and contour structures are complicated is
Main, holding burning face has scraggly stepped ramp type structure, in sintering each face can not be made to be contacted with ceramic wafer, forms effective
Planar support, the deformation condition such as produces very big bending, collapses, ftractures after sintering, causes higher after sintering scrap.
The content of the invention
In order to solve the above problems, the utility model provides a kind of powder injection-molded handset mounting semi-finished product.
The utility model is realized using following scheme：
A kind of powder injection-molded handset mounting semi-finished product, the handset mounting being made using the handset mounting semi-finished product can
It is fixed in a mobile phone shell body, the parts for fixing mobile phone, the handset mounting semi-finished product include rack body, and
It is arranged on multiple support columns on rack body the same face；The rack body is provided with the surface irregularity of support column, including
Multiple step surfaces；The multiple support column is on different step surfaces, support column upper surface and rack body highest step
Face is in the same plane.
Further, the support column includes the one or more in cylinder, prism.
Further, the cross sectional dimensions of the support column is less than the size of residing rack body step surface.
Prior art is contrasted, a kind of powder injection-molded handset mounting semi-finished product that the utility model is provided have as follows
Beneficial effect:
The utility model sets multiple support columns on handset mounting at diverse location, the step surface with rack body is common
A highly consistent supporting surface is formed, problem and therefore caused product are put when effectively improving handset mounting sintering
The defect of deformation, it is ensured that product design and appearance and size precision, so that yields is improved, and process is simple,
It is adapted to batch production.
Brief description of the drawings
A kind of powder injection-molded embodiment stereochemical structure of handset mounting semi-finished product one that Fig. 1 provides for the utility model
Schematic diagram.
Fig. 2 is the structural representation of the handset mounting finished product of the present embodiment.
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 handset mounting semi-finished product and handset mounting that the utility model is provided
Finished product, which is compared to have, includes rack body 1 and multiple support columns 2 on rack body 1.Utilize the handset mounting semi-finished product
The handset mounting being made can be fixed in a mobile phone shell body, the parts for fixing mobile phone.The support sheet of the handset mounting
Body 1 is substantially plate-like, constitutes multiple fixations or installation structure by forming the modes such as straight wall, depression thereon., will for convenience of description
The surface that opposing body's plate face has different height difference is defined as step surface 3, then is formed with the first face of rack body multiple
The different step surface 3 of area.Support column 2 is arranged at step surface 3 different on the first face.The upper surface of multiple support columns 2 with
The highest step surface 3 of rack body 1 is located in same level, and forming one is used for the supporting surface of supporting support body 1.Support column
2 shape includes two kinds of cylinder and prism, and the prism in the present embodiment is cuboid.Meanwhile, the cross sectional dimensions of support column 2 is small
Size of step surface where it.
Support column 2 is molded when carrying out powder injection together with rack body 1, and material is identical, and shrinkage factor is also consistent.Burning
During knot, the first of rack body 1 faces and earthward sets, then the supporting plane namely highest of support column 2 and rack body
Step surface collectively form the supporting surface of supporting support body 1, it is to avoid handset mounting occurs bending in sintering process, collapses,
The deformation such as cracking, advantageously ensures that handset mounting profile and appearance and size precision.After the completion of sintering, branch is removed by CNC processing
The handset mounting of finished product is can obtain after dagger, process is simple and yields is high, be adapted to batch production.
Although being to combine embodiments above to carry out to description of the present utility model, the art is familiar with
Personnel can carry out many replacements, modifications and variations according to above-mentioned content, be obvious.Therefore, it is all such to replace
Generation, improvement and change are included in scope of the appended claims.
