Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, a mold for molding a watch waterproof part by coating silica gel is used for molding waterproof sealing silica gel on the periphery of the watch waterproof part, and includes an upper template 1, a lower template 2 and a hot nozzle 3 for injecting glue. At least 1 fixing groove 4 is formed in the top surface of the lower template 2, and the fixing grooves 4 are used for fixing a watch waterproof part main body. And forming grooves 5 which are in one-to-one correspondence with the fixing grooves 4 are formed in the bottom surface of the upper template 1, and the hot nozzle 3 injects the melted glue into the forming grooves 5 from the upper part of the forming grooves 5. The circumferential width of the side wall of the forming groove 5 is changed from top to bottom and is arranged by first expanding and then contracting; when the upper template 1 and the lower template 2 are pressed, the fixing groove or the watch waterproof part main body is provided with a horizontal plane which is attached to the periphery of the bottom opening of the forming groove.
Specifically, after the watch waterproof part main body is fixed on the fixing groove 4, the upper template 1 is pressed downwards on the lower template 2 through an external lifting mechanism (not shown), and at the moment, the horizontal plane of the fixing groove or the horizontal plane of the watch waterproof part main body is attached to the periphery of the bottom opening of the forming groove; the molten glue is then injected into the forming groove 5 from above the forming groove 5 by means of the hot nozzle 3.
When the melted rubber material flows to the bottom opening periphery of the forming groove 5 from the side wall of the forming groove 5, the bottom opening of the forming groove 5 is in necking arrangement, the melted rubber material flows to the horizontal plane of the fixing groove or the horizontal plane of the watch waterproof part main body along the side wall of the forming groove 5, then the melted rubber material is gathered at the central position of the part of the watch waterproof part main body needing to be formed, the outward diffusion and seepage of the melted rubber material on the horizontal plane of the fixing groove or the horizontal plane of the watch waterproof part main body are effectively reduced, the condition of glue overflow during the formation of the periphery of the watch waterproof part is effectively reduced, and the overall waterproof effect of a watch after the watch waterproof part is applied is good.
Furthermore, a plurality of circles of waterproof reinforcing grooves 6 are sequentially formed on the side wall of the forming groove 5 from top to bottom; the circumferential width of all the waterproof reinforcing grooves is changed from top to bottom, and the waterproof reinforcing grooves are arranged in a manner of expanding firstly and then contracting secondly.
The setting of waterproof strengthening groove 6 makes the waterproof piece of wrist-watch behind the waterproof sealing silica gel of shaping, and the outside of waterproof sealing silica gel is the stairstepping setting, and this stairstepping setting makes the multiple waterproof sealing circle of surface formation of waterproof sealing silica gel, and waterproof sealing effect is better.
Preferably, the inner wall of the waterproof reinforcing groove 6 is arranged in a circular arc shape, and is designed to reduce sharp corners in the waterproof reinforcing groove 6. When demoulding, the scraping damage of the sharp angle of the mould to the formed waterproof sealing silica gel is reduced, and the integral quality is better.
In order to ensure that the upper template 1 and the lower template 2 are positioned more accurately during pressing, a guide sleeve 7 is formed on the lower template 2, and a guide post 8 is correspondingly formed on the upper template 1.
Furthermore, a positioning block 9 is installed on the top surface of the lower template 2, and a positioning groove 10 is correspondingly formed on the bottom surface of the lower template 2. The guide pillar 8 and the positioning block 9 are guided and positioned together, and the positioning is more accurate when the upper template 1 is pressed on the lower template 2.
In the embodiment of the utility model, a supporting seat 11 is fixed at the bottom side of the lower template 2, and an ejection mechanism is fixed in the supporting seat 11; the ejection mechanism comprises an ejector pin 12 and a lifting component 13 for driving the ejector pin 12 to lift, and a through hole 14 matched with the ejector pin 12 penetrates through the bottom wall of the fixing groove 4. After the waterproof sealing silica gel of periphery shaping of the waterproof piece of wrist-watch, the waterproof piece main part of wrist-watch is located fixed 4 inslots, and operator's accessible ejection mechanism is from the ejecting fixed slot 4 of the waterproof piece of wrist-watch in the below, and it is more convenient to get the piece.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
