Embodiment Construction

[0028] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0029] The specific embodiment of the present invention provides a kind of such as figure 1 The metal waterproof shell of the mobile phone shown includes a metal shell 10 and a silicone waterproof part 20 . Such as figure 2 As shown, the metal shell 10 includes a waterproof bone 11 protruding from its inner surface, and the inner surface of the metal shell 10 is formed by protruding upwards at positions on both sides of the waterproof bone 11 separated by a predetermined distance. The sealing boss 30, the inner surface of the metal shell 10 on at least one side of the sealing boss 30 is recessed to form an accommodating groove 40; the silicone waterproof part 20 is formed on the waterproof part by in-mold injection On the bone 11, and the side surface of the silicone waterproof part 20 has a convex part, such as Figure 6...

Abstract

The invention discloses a waterproof metal outer shell of an electronic product and a manufacturing method of the waterproof metal outer shell. According to the manufacturing method, a metal shell provided with a protrusive waterproof rib on the inner surface is formed, and the positions, spaced by a preset distance, on the two sides of the waterproof rib respectively protrude upwards to form a sealant boss; a mold is directly pressed on the sealant bosses, so that the sealant bosses deform, at least a part of each sealant boss is pressed in a containing groove, then a closed cavity is formed by the mold and the metal shell through the sealant bosses, then silica gel is injected to the cavity, the mold is opened after the silica gel is heated and vulcanized, a waterproof silica gel part integrated with the metal shell is formed on the waterproof rib, and the side surface or the top of the waterproof silica gel part is provided with a protrusive part. According to the waterproof metal outer shell, due to the design of the sealant bosses, when the waterproof metal outer shell is manufactured, silica gel overflowing and scratches on the surface of the metal product are not prone to occurring in the injection molding process, and compression or damage to the mold is also avoided.

Description

technical field [0001] The invention relates to an electronic product shell, in particular to a metal waterproof shell of an electronic product and a manufacturing method thereof. Background technique [0002] More and more 3C products (computer (Computer), communication (Communication) and consumer electronics (Consumer Electronics) combined, also known as "information home appliances"), especially smart phone products, require waterproof and dustproof functions . [0003] The traditional waterproof method is to install a silicone ring in the plastic shell. After assembly through the assembly, the waterproof function is achieved. The waterproof level of this method is limited, generally around IPX5, and the waterproof performance is easy to change after disassembly and reassembly. It is generally used for In structures with little or no dismantling. [0004] One of the more popular methods now is to use plastic and liquid silicone to form an integrated mold. The plastic p...
