Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0047] See also Figure 1 and Figure 2 , the embodiment of the present application provides a sealing mold 100, which is used to seal a product 300 and a workpiece 400 disposed on a surface of the product 300. The product 300 may be a display module, a frame, etc. of an electronic device, and the workpiece 400 may be a metal connecting sheet, a key waterproof module, etc. For ease of understanding and explanation, the embodiment of the present application takes the product 300 as a display module and the workpiece 400 as a metal connecting sheet as an example for explanation, and positions the mold closing direction as Figure 1 The Z-axis direction is shown, and obviously, this is not a limitation of the embodiments of the present application.
[0048] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the sealing mold 100 includes a lower mold 20 and an upper mold 10. The lower mold 20 is used to carry the product 300; the upper mold 10 and the lower mold 20 are molded and adapted.
[0049] A first sealing protrusion 111, a second sealing protrusion 112 and a third sealing protrusion 113 extending along the mold closing direction are convexly provided on one side of the upper mold 10 facing the lower mold 20. The first sealing protrusion 111 is used to abut against the edge of the product 300. The second sealing protrusion 112 and the third sealing protrusion 113 are used to abut against the side of the product 300 away from the lower mold 20. The second sealing protrusion 112 is spaced apart from the first sealing protrusion 111. A first sealing groove 114 is formed between the second sealing protrusion 112 and the first sealing protrusion 111. The third sealing protrusion 113 is located on the side of the second sealing protrusion 112 away from the first sealing protrusion 111, and both sides of the third sealing protrusion 113 are spaced apart from each other. The end is connected with the second sealing protrusion 112, and the second sealing groove 115 connected with the first sealing groove 114 is formed between the third sealing protrusion 113 and the second sealing protrusion 112. A contact boss 116 extending along the mold closing direction is also convexly provided on the side of the upper mold 10 facing the lower mold 20. The contact boss 116 is used to abut the workpiece 400, and the contact boss 116 is located in the second sealing groove 115. The first sealing groove 114 is used to receive glue 500 and seal the edge of the product 300. The second sealing groove 115 is used to receive glue 500 and the workpiece 400 and seal the workpiece 400 so that the glue 500 covers the area of the workpiece 400 that is not abutted by the abutment boss 116.
[0050] Specifically, in the present embodiment, the glue 500 is a light-curing glue, and the workpiece 400 is fixed on the surface of the product 300 and arranged close to the edge of the product 300, such as the workpiece 400 is adhered to the surface of the product 300 by means of a double-sided pressure-sensitive adhesive 600. When the product 300 is placed on the lower mold 20, the side of the product 300 facing away from the workpiece 400 abuts against the lower mold 20; when the upper mold 10 and the lower mold 20 are molded together, the first sealing protrusion 111 abuts against the edge of the product 300, the second sealing protrusion 112 and the third sealing protrusion 113 both abut against the side of the product 300 where the workpiece 400 is provided, the workpiece 400 is received in the second sealing groove 115, and the product 300 seals the first sealing groove 114 and the second sealing groove 115; when the glue 500 is injected into the first sealing groove 114, the glue 500 flows into the second sealing groove 115 while covering the edge of the product 300. The glue 500 covers the periphery of the workpiece 400 in the second sealing groove 115. In addition, since the abutting boss 116 abuts the workpiece 400, the cured glue 500 can not only surround the periphery of the workpiece 400, but also cover the area of the workpiece 400 that is not abutted against the abutting boss 116, thereby facilitating improving the structural strength of the glue sealing of the workpiece 400; in addition, since the abutting boss 116 can shield the area where the workpiece 400 abuts against the abutting boss 116, the area is not covered with glue 500, thereby not affecting the connection between the workpiece 400 and other components, thereby avoiding affecting the normal use of the workpiece 400.
[0051] In some other embodiments, the workpiece 400 may also be disposed in the middle or other area of a surface of the product 300. The same sealing effect can be achieved by simply adjusting the positions of the second sealing protrusion 112 and the third sealing protrusion 113 accordingly. The embodiments of the present application do not specifically limit this.
[0052] In this embodiment, since the product 300 and the workpiece 400 are both roughly flat, the heights of the second sealing protrusion 112 and the third sealing protrusion 113 are the same and smaller than the height of the first sealing protrusion 111, and the height of the abutment boss 116 is smaller than the heights of the second sealing protrusion 112 and the third sealing protrusion 113, thereby facilitating the product 300 to abut against the first sealing protrusion 111, the second sealing protrusion 112 and the third sealing protrusion 113 to close the first sealing groove 114 and the second sealing groove 115, and facilitating the abutment boss 116 to abut against the workpiece 400. In some other embodiments, if the product 300 and the workpiece 400 are arc-shaped or other shapes, the heights of the first sealing protrusion 111, the second sealing protrusion 112, the third sealing protrusion 113 and the abutting boss 116 can be set accordingly, so that the first sealing groove 114 and the second sealing groove 115 are closed after the product 300 abuts against the first sealing protrusion 111, the second sealing protrusion 112 and the third sealing protrusion 113, and the abutting boss 116 abuts against the workpiece 400. The embodiments of the present application do not specifically limit this.
[0053] In this embodiment, the abutting boss 116 abuts against a part of the side of the workpiece 400 away from the product 300. After the product 300 and the workpiece 400 disposed on a surface of the product 300 are sealed with glue, the area of the workpiece 400 away from the product 300 and the abutting boss 116 will not be covered by the glue 500, so that it is convenient to connect other parts to the side of the workpiece 400 away from the product 300, such as welding a bracket (not shown) in the area of the side of the workpiece 400 away from the product 300 that is not covered with the glue 500.
[0054] In this embodiment, the second sealing protrusion 112 is provided with a communication gap 117 communicating with the first sealing groove 114 and the second sealing groove 115, and the two ends of the third sealing protrusion 113 are respectively connected to the two ends of the communication gap 117 formed by the second sealing protrusion 112. In this way, it is convenient for the glue 500 to flow between the first sealing groove 114 and the second sealing groove 115, and it is convenient for a part of the workpiece 400 to extend into the first sealing groove 114 through the communication gap 117.
[0055] In this embodiment, the height of the abutting boss 116 is higher than the bottom height of the first glue sealing groove 114. When a portion of the workpiece 400 extends into the first glue sealing groove 114 through the connecting notch 117, the abutting boss 116 can lift the workpiece 400 to form a gap 1141 between the workpiece 400 and the bottom of the first glue sealing groove 114, so that the glue 500 can flow into the gap 1141 and wrap the portion of the workpiece 400 extending into the first glue sealing groove 114, which is beneficial to improve the structural strength of the glue sealing of the workpiece 400.
[0056] In this embodiment, the third sealing protrusion 113 conforms to the shape of the workpiece 400 , which helps to improve the uniformity of the sealing of the periphery of the workpiece 400 by the second sealing groove 115 .
[0057] In this embodiment, the distance between the third sealing protrusion 113 and the workpiece 400 is the same, for example, the distance between the third sealing protrusion 113 and the workpiece 400 may be in the range of 0.1 mm to 0.3 mm. This is beneficial to improve the uniformity of the peripheral sealing of the workpiece 400 by the second sealing groove 115, and when the workpiece 400 is received in the second sealing groove 115, it is possible to effectively prevent the workpiece 400 from contacting the third sealing protrusion 113 and cutting the third sealing protrusion 113.
[0058] In this embodiment, the first sealing protrusion 111 and the second sealing protrusion 112 are both annular, and the second sealing protrusion 112 is located on the inner side of the first sealing protrusion 111, and the third sealing protrusion 113 is located on the inner side of the second sealing protrusion 112. By setting the first sealing protrusion 111 and the second sealing protrusion 112 to be both annular, the first sealing groove 114 formed between the first sealing protrusion 111 and the second sealing protrusion 112 is also annular, so that the first sealing groove 114 can seal the periphery of the product 300, and by setting the third sealing protrusion 113 on the inner side of the second sealing protrusion 112, it is convenient to make the second sealing groove 115 face the workpiece 400 to seal the workpiece 400.
[0059] See also Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the upper mold 10 includes a sealing member 11 and a transparent cover plate 12. The sealing member 11 can be movably covered on the lower mold 20, and the first sealing protrusion 111, the second sealing protrusion 112 and the third sealing protrusion 113 are all arranged on the side of the sealing member 11 facing the lower mold 20. The sealing member 11 is provided with a light-transmitting opening 118, and the light-transmitting opening 118 is located on the side of the second sealing protrusion 112 away from the first sealing protrusion 111; the transparent cover plate 12 is arranged on the side of the sealing member 11 away from the lower mold 20 and closes the light-transmitting opening 118, and the transparent cover plate 12 is used to support the sealing member 11 and allow the curing light to pass through. Specifically, the first sealing protrusion 111, the second sealing protrusion 112 and the third sealing protrusion 113 are an integral structure with the sealing member 11, and the sealing member 11 is made of a material such as silicone that is conducive to shaping and has a certain degree of light transmittance, thereby facilitating the curing of the glue 500, sealing and demolding; the transparent cover plate 12 is made of glass or other materials, thereby having good light transmittance and high structural strength. By providing a transparent cover plate 12 to support the sealing member 11, the stability of the structure of the sealing member 11 can be improved, so that the sealing member 11 can be accurately pressed on the product 300 and the workpiece 400 to seal the product 300 and the workpiece 400; by opening a light-transmitting opening 118 on the sealing member 11, and the light-transmitting opening 118 is located on the side of the second sealing protrusion 112 away from the third sealing protrusion 113, it is convenient for the curing light to pass through the transparent cover plate 12 and the light-transmitting opening 118 to irradiate the first sealing protrusion 111, the second sealing protrusion 112 and the third sealing protrusion 113, which is beneficial to improve the curing speed of the glue 500 in the first sealing groove 115 and the second sealing groove 115.
[0060] In this embodiment, the upper mold 10 further includes a glue injection member 13, which passes through the transparent cover plate 12 and the glue sealing member 11 and extends into the first glue sealing groove 114. The glue injection member 13 is used to introduce glue 500 into the first glue sealing groove 114. Since the first glue sealing groove 114 and the second glue sealing groove 115 are connected, the glue injection member 13 is provided to facilitate the use of a glue injection machine (not shown) to quickly inject the glue 500 into the first glue sealing groove 114 and the second glue sealing groove 115 through the glue injection member 13.
[0061] In this embodiment, there are multiple glue injection parts 13 and they are evenly arranged along the extension direction of the first glue sealing groove 114 , which is beneficial to improve the uniformity of glue injection into the first glue sealing groove 114 and the second glue sealing groove 115 through the glue injection parts 13 .
[0062] In some other embodiments, the glue injection member 13 may also pass through the transparent cover plate 12 and the glue sealing member 11 and extend into the second glue sealing groove 115, and the glue injection member 13 is used to introduce the glue 500 into the second glue sealing groove 115. Since the first glue sealing groove 114 and the second glue sealing groove 115 are connected, when the second glue sealing groove 115 is large in size, it is also convenient to use a glue injection machine (not shown) to quickly inject the glue 500 into the second glue sealing groove 115 and the first glue sealing groove 114 through the glue injection member 13, and the embodiment of the present application does not specifically limit this.
[0063] In this embodiment, the sealant 11 is further provided with a support protrusion 119 extending toward the middle of the light-transmitting opening 118, and the support protrusion 119 is used to support the product 300. Since a certain pressure is applied to the product 300 when the upper mold 10 and the lower mold 20 are molded together to reduce the probability of glue overflow, by providing the support protrusion 119 to support the product 300, the mold-closing pressure can be more evenly distributed on the product 300, avoiding the pressure from being concentrated on the edge of the product 300, and effectively reducing the probability of the product 300 being crushed when the upper mold 10 and the lower mold 20 are molded together.
[0064] See also Figure 1 In this embodiment, the lower mold 20 includes a bearing seat 21 and a locking member 22. The bearing seat 21 is used to bear the product 300, and the upper mold 10 is movably covered on the bearing seat 21; the locking member 22 is rotatably disposed on the bearing seat 21, and the locking member 22 is used to abut against the side of the upper mold 10 away from the bearing seat 21 to lock the upper mold 10. Among them, the locking member 22 can be a cam handle, and the locking member 22 is rotatably disposed at the edge of the bearing seat 21. When the product 300 is placed on the bearing seat 21 and the upper mold 10 is pressed on the product 300, the upper mold 10 can be locked by turning the locking member 22, so that the upper mold 10 can continue to press the product 300. In this way, by setting the locking member 22 to lock the upper mold 10, the probability of glue overflow when the sealing mold 100 seals the product 300 and the workpiece 400 can be effectively reduced.
[0065] In some other embodiments, the upper mold 10 may also be continuously pressed by providing a pressing mechanism (not shown), which is not specifically limited in the embodiments of the present application.
[0066] In one embodiment, a positioning pin (not shown) or a positioning groove (not shown) may be further provided on the bearing seat 21 to position the product 300 , thereby facilitating improving the accuracy of the sealing mold 100 when sealing the product 300 and the workpiece 400 .
[0067] To summarize, the sealing mold 100 of the embodiment of the present application is provided with a first sealing protrusion 111, a second sealing protrusion 112, a third sealing protrusion 113 and an abutting boss 116 on the side of the upper mold 10 facing the lower mold 20, and a first sealing groove 114 is formed between the second sealing protrusion 112 and the first sealing protrusion 111, a second sealing groove 115 is formed between the third sealing protrusion 113 and the second sealing protrusion 112, and the abutting boss 116 is located in the second sealing groove 115. When the upper mold 10 and the lower mold 20 are closed to seal the product 300 and the workpiece 400, the first sealing groove 114 seals the edge of the product 300 by receiving the glue 500, and the second sealing groove 115 seals the workpiece 400 by receiving the workpiece 400 and the glue 500, and the abutting boss 116 can lift the workpiece 400 while abutting the workpiece 400. Therefore, the cured glue 500 can not only surround the periphery of the workpiece 400, but also cover the area of the workpiece 400 that is not abutted by the abutting boss 116, which is beneficial to improve the structural strength of the seal of the workpiece 400; in addition, because the abutting boss 116 can shield the area where the workpiece 400 abuts against the abutting boss 116, the area is not covered with glue 500, so that it will not affect the connection between the workpiece 400 and other components, avoiding affecting the normal use of the workpiece 400.
[0068] The embodiment of the present application also provides a sealing device (not shown), including the above-mentioned sealing mold 100. By providing the sealing mold 100, the structural strength of the sealing of the workpiece 400 can be improved and the normal use of the workpiece 400 can be avoided.
