As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following embodiments, features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, 2, 3 and 5, in one embodiment, the insert 100 is used in an injection molding apparatus to seal a gap between the handset interface 200 and the housing 300, and the gap is used to inject plastic to form a plastic layer 400. The plastic layer 400 serves to insulate the interface 200 from the housing 300. The housing 300 is provided with an opening 310, and the opening 310 is used for receiving the interface 200. The plastic layer 400 is filled between the interface outer wall 210 of the interface 200 and the opening inner wall 311 of the opening 310. A slot 220 is provided in the interface 200. The inlet 100 is provided with a first boss 110. The first boss 110 is provided with a second boss 120. A sealing compound inclined plane 130 is arranged between the first peripheral wall 111 of the first boss 110 and the second peripheral wall 121 of the second boss 120. The first boss 110 is for insertion into the opening 310. The first peripheral wall 111 is for sufficiently contacting the opening inner wall 311 to be sealed. The second boss 120 is for insertion into the insertion slot 220. The molding compound slope 130 is used to fully contact the interface sidewall 230 of the interface 200 and extend to the opening inner wall 311 to form a gap between the interface 200 and the housing 300.
In order to prevent the insert 100 from falling off the PVD layer of the interface 200 and simultaneously avoid flash phenomenon, in one embodiment, the material of the insert 100 is aluminum, so that the hardness of the insert 100 is lower than that of the interface 200. When the insert 100 is inserted into the interface 200, the PVD coating of the interface 200 will not fall off due to the low hardness of the insert 100. Meanwhile, since the hardness of the insert 10 is low, after the sealing compound inclined plane 130 of the insert 100 contacts the interface sidewall 230 of the interface 200, the insert 100 is elastically deformed according to the shape of the interface sidewall 230, so as to more fully form a gap between the interface 200 and the housing 300.
Referring to fig. 4, 5 and 6, the interface 200 has a slot inner wall 240 in the slot 220. The interface sidewall 230 and the socket inner wall 240 form a first acute angle α with respect to the opening of the socket 220. The molding compound slope 130 has the same curved shape as the interface sidewall 230. The direction between the molding compound inclined plane 130 and the inner wall 240 of the slot 220 is a second acute angle β. In order to make the molding compound slope 130 and the interface sidewall 230 sufficiently contact to seal, the second acute angle β is slightly larger than the first acute angle α. The purpose is that in the process of the contact between the sealant slope 130 and the interface sidewall 230 (the screw 500 generates a mutual pressing force between the sealant slope 130 and the interface sidewall 230), the sealant slope 130 elastically deforms according to the shape of the interface sidewall 230 to fully contact the interface sidewall 230, so as to prevent the molten plastic layer 400 from flowing out from the gap between the sealant slope 130 and the interface sidewall 230 (avoid the phenomenon of sealant overflow).
Referring to fig. 3 and 6, the inner wall 240 of the socket 220 is coated with a PVD coating. In order to prevent the second protrusion 120 from contacting the inner wall 240 of the slot, a gap is formed between the second peripheral wall 121 of the second protrusion 120 and the inner wall 240 of the slot of the interface 200, so as to avoid the problem of falling off of the PVD plating layer caused by the point-to-point contact between the interface 200 and the insert 100.
Referring to fig. 3, the insert 100 is provided with a screw hole 140 penetrating through the first boss 110 and the second boss 120. The interface 200 is provided with corresponding screw holes 250. The interior of screw holes 140, 250 are used to mount a screw 500. screw 500 is used to fasten interface 200 to insert 100.
Referring to fig. 4, 5 or 6, the outer wall 210 of the interface 200 and the inner wall 311 of the opening of the housing 300 are respectively provided with grooves 211 and 312. The recesses 211, 312 serve to increase a contact area with the plastic layer 400 to fix the plastic layer 400.
In one embodiment, the interface sidewall 230 is an asymmetric annular curved surface, and the first acute angle α (the inclination angle of the curved surface) is 45 °. The shape of the molding compound slope 130 of the inlet 100 is the same as the curved surface shape of the interface sidewall 230, and the second acute angle β is 47 °. In the process of contacting the inlet 100 and the interface 200, because the hardness of the inlet 100 is lower than that of the interface 200, the glue sealing inclined surface 130 of the glue sealing of the inlet 100 can generate elastic deformation with maximum overpressure of 0.01 mm (the inlet 10 generates elastic deformation to adapt to the curved surface shape of the interface side wall 230) according to the asymmetric curved surface shape of the interface side wall 230 under the action of the high temperature of the molten plastic, the injection pressure of the molten plastic and the pressure of the mold, so that the glue sealing inclined surface 130 is accurately matched with the interface side wall 230, and the glue sealing effect is ensured.
In one embodiment, an injection molding apparatus (not shown) is used to mold a plastic layer 400 into a gap between a handset interface 200 and a housing 300, and the injection molding apparatus includes the above-mentioned insert 100 to prevent the interface 200 from overflowing and the PVD layer from falling off.
It is understood that in other embodiments of the present invention, the material of insert 100 may be other low hardness materials; the first acute angle α and the second acute angle β may be other angles; the interface 200 and the inlet 100 can be fixed in other ways; plastic layer 400 may be other injection molded materials.
The insert 100 and the injection molding equipment with the insert achieve the purpose of avoiding glue overflow of the interface 200 and falling off of the PVD coating.
The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention. Those skilled in the art can also make other changes and the like in the spirit of the present invention, and the design of the present invention can be used as long as the technical effects of the present invention are not deviated. Such variations are intended to be included within the scope of the invention as claimed.
