Description
Technical field
Mobile phone component technical field is the utility model is related to, more particularly, to a kind of mobile phone sound chamber enclosure.
Background technology
In mobile phone sound chamber enclosure injection moulding process, cast gate defective material often occurs at mould injection port, and defective material is dashed forward
For the outer surface of product, the attractive in appearance of product is have impact on, and also can scratch or stab when mounted staff, causing need not
The trouble wanted.
Utility model content
The technical problems to be solved in the utility model is：In order to solve often to occur that cast gate is residual at mould injection port
Material, and defective material protrudes from the outer surface of product, have impact on the attractive in appearance of product, and also can scratch or stab when mounted work
Personnel, the problem of causing unnecessary trouble, now provide a kind of mobile phone sound chamber enclosure.
Technical scheme is used by the utility model solves its technical problem：A kind of mobile phone sound chamber enclosure, including housing,
One end of the housing has outer chamber wall and encloses opening up cavity body, and the lateral surface of the outer chamber wall is provided with to cavity
The groove of body direction depression.By setting groove in outer chamber wall, and groove is located at die casting mouth, and glue is stolen at cast gate,
Cast gate defective material will not be above the outer surface of product.
In order to prevent occurring phenomenon of rupture at product sprue gate, further, the outer chamber wall, which has to finish up successively, to be connected
The first wall and the second wall composition, second wall be located at the groove, the wall of the wall thickness of first wall less than the second wall
It is thick.By the wall thickness for having thickeied the second wall so that for product in injection, melt plastic cement has bigger space to carry out at the second wall
Buffering, reduces the internal stress of product, effectively prevents product stress concentration and the phenomenon being broken occur, while also increase this
Locate the mobility of plastic cement, improve properties of product.
The beneficial effects of the utility model are：The utility model mobile phone sound chamber enclosure when in use, by the outer of housing
Groove is set, and groove is corresponding with die casting mouth so that cast gate defective material will not be above the outer surface of product, just in cavity wall
Hand will not be left over, avoids and cast gate defective material often occurs at mould injection port, and defective material protrudes from the outer surface of product,
The attractive in appearance of product is have impact on again, and also can scratch or stab when mounted staff, the problem of causing unnecessary trouble.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model mobile phone sound chamber enclosure；
Fig. 2 is the top view of the utility model mobile phone sound chamber enclosure；
Fig. 3 is the partial enlarged drawing of A in Fig. 2.
In figure：1st, housing, 2, outer chamber wall, 3, cavity body, 4, groove, the 5, first wall, the 6, second wall.
Embodiment
Presently in connection with accompanying drawing, the utility model is described in more detail.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
Embodiment
As Figure 1-3, a kind of mobile phone sound chamber enclosure, including housing 1, one end of the housing 1 have outer chamber wall 2 and enclosed
Opening up cavity body 3 is synthesized, the lateral surface of the outer chamber wall 2 is provided with the groove 4 being recessed to the direction of cavity body 3.
The outer chamber wall 2 has finishes up the first connected wall 5 and the second wall 6 forms successively, and second wall 6 is positioned at described
At groove 4, the wall thickness of first wall 5 is less than the wall thickness of the second wall 6.
Above-mentioned mobile phone sound chamber enclosure is when using, by being set in the outer chamber wall 2 of housing 1 to the recessed of the depression of cavity body 3
Groove 4, groove 4 and cast gate during die casting are to corresponding, and when cast gate is in glue steathily, the defective material at cast gate will not also be higher by product
Outer surface so that defective material is not easy to leave over hand, while the thickness of the first wall 5 is less than the thickness of the second wall 6, also increases mould
The space at sprue gate so that the region on sprue gate opposite thickeies, and adds the cushion space that plastic cement is injected at sprue gate, reduces product
Internal stress, also increase the mobility of plastic cement herein, improve properties of product.
It is above-mentioned according to desirable embodiment of the present utility model for enlightenment, pass through above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely.This item is practical
New technical scope is not limited to the content on specification, it is necessary to determines that its is technical according to right
Scope.
