Abstract
本实用新型公开了一种手机中框产品指纹孔的注塑结构，包括有后模，后模上端设置有产品模腔，且产品模腔上端设置有指纹孔，指纹孔上端设置有前模仁，且前模仁上端盖装有注塑的塑胶件。本实用新型通过在指纹孔上端设置注塑的塑胶件，且塑胶件上端部的壁厚H为0.1mm，使得指纹孔在注塑成型后成为盲孔，从而防止注塑时出现披锋，注塑后的产品在CNC精铣反面的时候，顺便在指纹孔边缘CNC倒斜角，加工出斜角特征，同时去除了先前增加壁厚0.1mm的塑胶件；故本实用新型具有设计新颖、结构简单，有效防止出现严重披锋，大大提高了生产效率的优点。
The utility model discloses an injection molding structure for a fingerprint hole of a product in a middle frame of a mobile phone, which comprises a rear mold, a product mold cavity is arranged on the upper end of the rear mold, a fingerprint hole is arranged on the upper end of the product mold cavity, and a front mold core is arranged on the upper end of the fingerprint hole. And the upper end cover of the front mold core is equipped with an injection-molded plastic part. In the utility model, an injection-molded plastic part is arranged on the upper end of the fingerprint hole, and the wall thickness H of the upper end of the plastic part is 0.1 mm, so that the fingerprint hole becomes a blind hole after injection molding, thereby preventing the appearance of sharp edges during injection molding, and the product after injection molding When CNC fine-milling the reverse side, by the way, CNC chamfers the edge of the fingerprint hole to process the bevel feature, and at the same time removes the previous plastic parts with a wall thickness of 0.1 mm; therefore, the utility model has novel design, simple structure, and can effectively prevent It has the advantage of serious draping, which greatly improves the production efficiency.
Description
Technical Field
The utility model relates to an injection mould technical field especially relates to an injection structure in cell-phone center product finger print hole.
Background
The through-hole is usually in cell-phone center product fingerprint hole, and the mould need be done the front and back mould and bump and wear to seal glued structure, because the center aluminum alloy spare comes material thickness to differentiate, and nanometer injection mold mould temperature is very high in addition, and plastic material mobility is fine, leads to the fingerprint hole to bump face department and appear seriously drape over one's hair badly, influences the mould volume production.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an injection structure in cell-phone center product finger print hole to prior art's not enough, this injection structure in cell-phone center product finger print hole novel in design, simple structure effectively prevent to appear seriously draping over one's hair, have improved production efficiency greatly.
In order to achieve the above purpose, the present invention is achieved by the following technical solutions.
The utility model provides an injection structure in cell-phone center product fingerprint hole, is including back mould, and back mould upper end is provided with the product die cavity, and product die cavity upper end is provided with the fingerprint hole, and fingerprint hole upper end is provided with front mould benevolence, and front mould benevolence upper end cover is equipped with the plastic part of moulding plastics.
Wherein, the material of the back mould is aluminum alloy.
Wherein, the wall thickness H of the upper end part of the plastic part is 0.1 mm.
Wherein, the upper end of the front mould core is provided with a cylindrical fingerprint hole convex column.
The utility model has the advantages that: a cell-phone center product fingerprint hole's injection structure, including back mould, back mould upper end is provided with the product die cavity, and is provided with the fingerprint hole on the product die cavity, fingerprint hole upper end is provided with front mould benevolence, and front mould benevolence upper end cover is equipped with the plastic part of moulding plastics. The utility model discloses a set up the plastic part of moulding plastics in fingerprint hole upper end, and the wall thickness H of plastic part upper end is 0.1mm, make the fingerprint hole become the blind hole after injection moulding to prevent to turn over one's hair when moulding plastics, the product after moulding plastics is when CNC finish milling reverse side, by the way fingerprint hole edge CNC chamfer angle, process out the oblique angle characteristic, has removed the plastic part that increases wall thickness 0.1mm before simultaneously; the event the utility model has the advantages of novel in design, simple structure effectively prevent to appear seriously draping over one's shoulders the cutting edge of a knife or a sword, have improved production efficiency greatly.
Drawings
The invention will be further described with reference to the drawings, but the embodiments in the drawings do not constitute any limitation of the invention.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the partial cross-sectional structure of the present invention.
Included in fig. 1-2 are:
1-rear mould 11-product mould cavity
12-fingerprint hole 2-front mould core
21-plastic piece 22-fingerprint hole convex column.
Detailed Description
The present invention will be described with reference to specific embodiments.
As shown in fig. 1-2, an injection structure for a fingerprint hole of a middle frame product of a mobile phone includes a rear mold 1, a product mold cavity 11 is disposed at an upper end of the rear mold 1, a fingerprint hole 12 is disposed at an upper end of the product mold cavity 11, a front mold core 2 is disposed at an upper end of the fingerprint hole 12, and an injection molded plastic part 21 is covered at an upper end of the front mold core 2.
Preferably, in this embodiment, the material of the rear mold 1 is an aluminum alloy.
Further, the wall thickness H of the upper end part of the plastic part 21 is 0.1 mm.
Furthermore, the upper end of the front mold core 2 is provided with a cylindrical fingerprint hole convex column 22.
The utility model has the advantages that the injection-molded plastic part 21 is arranged at the upper end of the fingerprint hole 12, and the wall thickness H of the upper end of the plastic part 21 is 0.1mm, so that the fingerprint hole 12 becomes a blind hole after injection molding, and burrs are prevented from occurring during injection molding, when the back surface of the injection-molded product is subjected to CNC (computer numerical control) finish milling, the CNC chamfering is carried out on the edge of the fingerprint hole, the bevel angle characteristic is processed, and meanwhile, the plastic part 21 with the wall thickness increased by 0.1mm in the prior art is removed; the event the utility model has the advantages of novel in design, simple structure effectively prevent to appear seriously draping over one's shoulders the cutting edge of a knife or a sword, have improved production efficiency greatly.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
