[0056] The following will describe in detail the housing potting and forming fixture 1000 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0057] Refer to Figures 1 to 5 As shown, the housing potting and forming fixture 1000 according to an embodiment of the present utility model includes a fixture base 10, an upper cover plate 20, and a locking member 30 for clamping and fixing the fixture base 10 and the upper cover plate 20.

[0058] Wherein, a potting cavity 10a for forming the housing 2000 having the structure as Figure 5 shown is formed by downwardly opening the upper end surface of the fixture base 10; the upper cover plate 20 is laminated and pressed on the upper end surface of the fixture base 10 to seal the potting cavity 10a, and a glue inlet 201 and a glue outlet 202 communicating with the potting cavity 10a are opened on the upper end surface of the upper cover plate 20; the locking member 30 is arranged between the fixture base 10 and the upper cover plate 20.

[0059] Based on the above, it can be clear that in specific implementation, the present application is mainly used as the housing potting and forming fixture 1000.

[0060] Specifically, when applying the present application, the upper cover plate 20 is laminated and pressed on the upper end surface of the fixture base 10 to seal the potting cavity 10a, and the fixture base 10 and the upper cover plate 20 are clamped and fixed by the locking member 30. Then, glue is poured into the potting cavity 10a from the glue inlet 201, and the pouring is stopped when the glue in the potting cavity 10a is full. After the glue in the potting cavity 10a is cured and formed into the required housing 2000, the locking member 30 can be controlled to loosen the fixture base 10 and the upper cover plate 20. At this time, the cured and formed housing 2000 can be taken out.

[0061] Obviously, for the above use of the present application, it will have the following technical effects:

[0062] On the one hand, when forming the housing 2000, the present application adopts a potting molding process with fewer related process operation steps, making the molding of the housing 2000 less difficult.

[0063] On the other hand, the overall structure of the present application is simple, including only three major structural components: the fixture base 10, the upper cover plate 20, and the locking member 30 for clamping and fixing the fixture base 10 and the upper cover plate 20. With fewer structural components and simple and uncomplicated operation, the manufacturing cost of the housing 2000 is low.

[0064] Furthermore, through the above optimization design, the overall structure formed by the present application has strong practicability and good use effect.

[0065] Further, in specific implementation, referring to Figure 2 and Figure 4 shown, according to an embodiment of the present invention, the fixture base 10 includes a bottom support plate 101 and a detachable fixture table 102 stacked and fixed in the middle of the upper end surface of the bottom support plate 101;

[0066] Among them, a potting cavity 10a is opened downward on the upper end surface of the detachable fixture table 102; the upper cover plate 20 is stacked and pressed on the upper end surface of the detachable fixture table 102; the locking member 30 is arranged between the bottom support plate 101 and the upper cover plate 20.

[0067] In this regard, it can be clearly understood that when the outer peripheral dimensions of the detachable fixture table 102 are basically unchanged, it is adapted to be fixed on the upper end surface of the bottom support plate 101 through the locking member 30, and then according to the shape and structure of the product, the shape and structure of the potting cavity 10a opened downward on its upper end surface are adaptively designed, so that the detachable fixture table 102 can be adaptively replaced according to the product to be molded. In this way, the present application has strong use flexibility and adaptability. When molding products that need potting, only the detachable fixture table 102 needs to be replaced.

[0068] Preferably, in this technical solution, continuing to refer to Figure 2 and Figure 4 shown, according to an embodiment of the present invention, the fixture base 10 further includes a heating plate 103 clamped and fixed between the bottom support plate 101 and the detachable fixture table 102 for heating the detachable fixture table 102.

[0069] Thus, by setting the heating plate 103, after the potting cavity 10a is filled with glue, the detachable fixture table 102 can be heated through the heating plate 103 to heat and cure the glue filled in the potting cavity 10a, so that the molding speed of the molded product that needs potting can be accelerated.

[0070] Moreover, in this technical solution, still referring to Figure 2 and Figure 4 As shown, according to an embodiment of the present utility model, a clamping portion 104 for clamping the peripheral side walls of the detachable jig table 102 is provided on the periphery of the heating plate 103, and a groove 1031 is formed by downward depression in the middle of the upper end surface of the heating plate 103. A bottom convex portion 1021 adapted to be press-fitted and clamped into the groove 1031 protrudes downward from the lower bottom surface of the detachable jig table 102.

[0071] Thus, by providing the clamping portion 104 to clamp and fix the peripheral side walls of the detachable jig table 102, and providing the groove 1031 to clamp the bottom convex portion 1021 to limit and fix the detachable jig table 102, during the use of this application, the detachable jig table 102 is fixed firmly and reliably and is not prone to circumferential displacement.

[0072] Furthermore, in specific implementation, still referring to Figure 2 and Figure 4 As shown, according to an embodiment of the present utility model, a card slot 203 adapted to be press-fitted and framed outside the detachable jig table 102 is formed upward in the middle of the lower bottom surface of the upper cover plate 20. A demolding plate 204 that can be press-fitted and extend into the upper part of the glue filling cavity 10a is detachably fixed in the middle of the card slot 203;

[0073] Wherein, a hollow glue inlet head 2041 that is press-fitted and clamped into the glue inlet 201 and penetrates to its lower bottom surface protrudes upward from the upper end surface of the demolding plate 204, and a hollow glue outlet head 2042 that is press-fitted and clamped into the glue outlet 202 and penetrates to its lower bottom surface protrudes upward.

[0074] In this regard, it can be clearly understood that when using this application specifically, when the card slot 203 is press-fitted and framed outside the detachable jig table 102 and the demolding plate 204 is press-fitted and extends into the upper part of the glue filling cavity 10a, it not only makes the fixing stability between the upper cover plate 20 and the detachable jig table 102 good, but also makes the upper cover plate 20 not prone to circumferential displacement. At the same time, it also makes the glue filling cavity 10a have good sealing performance and is not prone to leaking glue outward.

[0075] Moreover, since the upper end face of the demolding plate 204 is convexly provided with an interference-fit hollow glue inlet head 2041 that is inserted into the glue inlet 201 and penetrates to its lower bottom surface, and a hollow glue outlet head 2042 that is convexly provided with an interference-fit insertion into the glue outlet 202 and penetrates to its lower bottom surface, there will be no glue leakage gap between the demolding plate 204 and the upper cover plate 20. The glue directly enters the glue filling cavity 10a from the hollow glue inlet head 2041, and the excess glue in the glue filling cavity 10a is directly discharged from the hollow glue outlet head 2042.

[0076] In addition, in this technical solution, as shown in Figure 1 and Figure 2 According to an embodiment of the present invention, a glue inlet sealing plug 40 is pluggably inserted outside the hollow glue inlet head 2041, and a glue outlet sealing plug 50 is pluggably inserted outside the hollow glue outlet head 2042.

[0077] Thus, when the glue filling cavity 10a is filled with glue, the glue inlet sealing plug 40 is inserted outside the hollow glue inlet head 2041, and the glue outlet sealing plug 50 is inserted outside the hollow glue outlet head 2042, which is convenient for extruding the unnecessary glue in the hollow glue inlet head 2041 and the hollow glue outlet head 2042, so as to achieve precise sealing of the glue filling cavity 10a. When the glue in it cures and forms products such as the housing 2000, there are not likely to be many burrs remaining on its outer surface at the hollow glue inlet head 2041 and the hollow glue outlet head 2042. Specifically, as shown in Figure 5 This is a schematic diagram of the overall structure of the housing 2000 formed by glue filling and molding using the housing glue filling and molding fixture 1000 of the present invention. When curing and forming products such as the housing 2000 required, the product quality can be effectively guaranteed.

[0078] Furthermore, in specific implementation, as shown in Figure 2 and Figure 4 According to an embodiment of the present invention, the locking member 30 includes a first inverted U-shaped locking member 301 and a second inverted U-shaped locking member 302;

[0079] Among them, the two lower ends of the first inverted U-shaped locking member 301 are rotatably connected to the left side of the bottom plate 101 through a first rotating shaft member 60 arranged in the front-rear direction; the two lower ends of the second inverted U-shaped locking member 302 are rotatably connected to the right side of the bottom plate 101 through a second rotating shaft member 70 arranged in the front-rear direction;

[0080] Moreover, a left clamping block 205 is provided on the left middle part of the upper cover plate 20 extending leftward, and a right clamping block 206 is provided on the right middle part extending rightward;

[0081] When the first inverted U-shaped locking member 301 rotates upward from the horizontal direction to the vertical direction, the left clamping block 205 is clamped between the left upper end surface of the bottom support plate 101 and the inner top surface of the first inverted U-shaped locking member 301; when the second inverted U-shaped locking member 302 rotates upward from the horizontal direction to the vertical direction, the right clamping block 206 is clamped between the right upper end surface of the bottom support plate 101 and the inner top surface of the second inverted U-shaped locking member 302.

[0082] Conversely, when the first inverted U-shaped locking member 301 rotates downward from the vertical direction to the horizontal direction, the left clamping block 205 can be released; when the second inverted U-shaped locking member 302 rotates downward from the vertical direction to the horizontal direction, the right clamping block 206 can be released. At this time, it is convenient to remove the upper cover plate 20 to take out products such as the cured and formed housing 2000 from the potting cavity 10a.

[0083] Obviously, in the present application, when the locking member 30 includes the first inverted U-shaped locking member 301 of the structure and the second inverted U-shaped locking member 302 of the structure, their operations can be made simple, making the present application convenient to use.

[0084] Preferably, in this technical solution, continue to refer to Figure 2 and Figure 4 As shown, according to an embodiment of the present invention, a first elastic abutting member 3011 is fixedly provided along the vertical direction on the inner top surface of the first inverted U-shaped locking member 301, and a left clamping groove 2051 is formed by downward depression of the upper end surface of the left clamping block 205 in the front-rear direction.

[0085] When the first inverted U-shaped locking member 301 rotates upward from the horizontal direction to the vertical direction, the first elastic abutting member 3011 elastically snaps into the left clamping groove 2051, so that the left clamping block 205 is fixedly arranged on the left upper end surface of the bottom support plate 101 in a fitting manner; when the first inverted U-shaped locking member 301 rotates downward from the vertical direction to the horizontal direction, the first elastic abutting member 3011 elastically extrudes out of the left clamping groove 2051.

[0086] And preferably, in this technical solution, still refer to Figure 2 and Figure 4 As shown, according to an embodiment of the present invention, a second elastic abutting member 3021 is fixedly provided along the vertical direction on the inner top surface of the second inverted U-shaped locking member 302, and a right clamping groove 2061 is formed by downward depression of the upper end surface of the right clamping block 206 in the front-rear direction.

[0087] When the second inverted U-shaped locking member 302 rotates upward from the horizontal direction to the vertical direction, the second elastic abutting member 3021 elastically snaps into the right clamping groove 2061, so that the right clamping block 206 is fixedly arranged on the upper right end surface of the bottom support plate 101 in a fitting manner; when the second inverted U-shaped locking member 302 rotates downward from the vertical direction to the horizontal direction, the second elastic abutting member 3021 elastically extrudes the left clamping groove 2051.

[0088] In this regard, it can be clearly seen that:

[0089] On the one hand, for the use of the first inverted U-shaped locking member 301, by arranging the first elastic abutting member 3011 to elastically snap into the left clamping groove 2051 in cooperation, it is realized that the left clamping block 205 is fixedly arranged on the upper left end surface of the bottom support plate 101 in a fitting manner, and for the use of the second inverted U-shaped locking member 302, by arranging the second elastic abutting member 3021 to elastically snap into the right clamping groove 2061 in cooperation, it is realized that the right clamping block 206 is fixedly arranged on the upper right end surface of the bottom support plate 101 in a fitting manner. In this way, it is convenient to fixedly arrange the upper cover plate 20 on the bottom support plate 101 to firmly press the detachable jig table 102.

[0090] On the other hand, when the first inverted U-shaped locking member 301 rotates downward from the vertical direction to the horizontal direction, so that the first elastic abutting member 3011 elastically extrudes the left clamping groove 2051, and when the second inverted U-shaped locking member 302 rotates downward from the vertical direction to the horizontal direction, so that the second elastic abutting member 3021 elastically extrudes the left clamping groove 2051, it is convenient to loosen the upper cover plate 20 and the bottom support plate 101, so as to remove the upper cover plate 20 and the stripping plate 204 at its bottom, so as to realize taking out products such as the cured and formed housing 2000 from the glue injection cavity 10a.

[0091] Furthermore, through the above optimized design, the overall structure of the present application can effectively improve the use effect.

[0098] It further needs to be supplemented that, in specific implementation, according to the housing potting and forming fixture 1000 provided by the embodiments of the present utility model, for the potting and forming product, its process steps mainly include glue application, glue application compaction and heat curing; while the process steps of injection molding generally include loading, heating, mold closing, plastic forming, mold opening, demolding, inspection and release; the formed product of potting is a filling body, while the formed product of injection molding is a plastic part; potting can fill any voids, while injection molding can only fill specific cavities; potting can be used for waterproofing, dustproofing, heat insulation, shock absorption, etc., while injection molding is generally used for manufacturing various plastic parts; potting usually does not require a forming tool, while injection molding requires a mold.

[0099] Therefore, by using the present application to perform glue injection molding on the required housing 2000 (such as a watch case, etc.), it has very good advantages both in terms of the molding process and the molding cost.

[0100] For other embodiments, etc., no examples will be given here.

[0101] In summary, for the housing glue injection molding fixture 1000 provided by the present application, during specific implementation, when molding the housing 2000, the present application adopts the glue injection molding process, with fewer related process operation steps, making the molding of the housing 2000 less difficult. Moreover, the overall structure of the present application is simple, including only three major structural components: the fixture base 10, the upper cover plate 20, and the locking member 30 for clamping and fixing the fixture base 10 and the upper cover plate 20. There are few structural components and the operation is simple and not complex, resulting in a low manufacturing cost for the housing 2000.

[0102] Furthermore, when the outer peripheral dimensions of the detachable fixture table 102 are basically unchanged, it is adapted to be fixed to the upper end surface of the bottom support plate 101 through the locking member 30, and then according to the shape and structure of the product, the shape and structure of the glue injection cavity 10a opened downward on its upper end surface are adaptively designed, that is, the detachable fixture table 102 can be adaptively replaced according to the product to be molded. In this way, the present application has strong flexibility and adaptability in use. When dealing with different molded products that require glue injection, only the detachable fixture table 102 needs to be replaced.

[0103] In addition, by setting the heating plate 103, after the glue injection cavity 10a is filled with glue, the detachable fixture table 102 can be heated through the heating plate 103, so that the glue filled in the glue injection cavity 10a is heated and cured, and the molding speed of the molded product that needs glue injection can be accelerated.

[0104] Moreover, when the glue injection cavity 10a is filled with glue, the glue injection sealing plug 40 is inserted outside the hollow glue inlet head 2041, and the glue outlet sealing plug 50 is inserted outside the hollow glue outlet head 2042, which is convenient for extruding the unnecessary glue in the hollow glue inlet head 2041 and the hollow glue outlet head 2042, so as to achieve precise sealing of the glue injection cavity 10a. When the glue in it is cured to form products such as the housing 2000, less burrs are likely to remain on the outer surface at the hollow glue inlet head 2041 and the hollow glue outlet head 2042. Therefore, when curing and molding products such as the housing 2000 required, the product quality can be effectively guaranteed.

[0105] Furthermore, the shell potting and forming fixture 1000 provided by the present application is indeed extremely practical and has excellent use effects, making it inevitable that the present application will have great market promotion value, and the present application will also be very popular and will surely be effectively popularized.
