[0083] An embodiment of the present application provides a molding device, comprising: a first mold and a second mold adapted to be clamped together; a light-transmitting molding mold core, arranged between the first mold and the second mold, for accommodating a workpiece and cooperating with the first mold and the workpiece to form a molding cavity, the molding cavity being used to accommodate a rubber material so that the rubber material is cured and connected to the workpiece; wherein the second mold is provided with a light-transmitting area corresponding to the molding cavity, the light-transmitting area being used to transmit light to promote the curing of the rubber material.
[0084] In the molding device provided in the embodiment of the present application, after the workpiece is clamped in the molding mold, the workpiece is fixed to the molding mold through the cooperation of the first mold and the second mold, and rubber is injected into the molding cavity formed by the cooperation of the molding mold, the first mold, and the workpiece. Light is passed through the light-transmitting area and through the molding mold to irradiate the rubber in the molding cavity, so that the rubber can be quickly cured under the irradiation of light, thereby reducing the curing time of the rubber, improving the efficiency of the rubber curing, and reducing the manufacturing cost.
[0085] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0086] See also Figure 1 and Figure 2 , some embodiments of the present application provide a molding device 100. The molding device 100 is used to accommodate a workpiece 200 and inject glue (not shown). After the glue is cured and molded, it is connected to the workpiece 200 to form a molded part 201 on the workpiece 200. The molded part 201 can be a small part such as a wrapping part, a cover or a column on the workpiece 200, or a structure connecting various parts on the workpiece 200. In this embodiment, the glue is UV glue, but it can also be other photosensitive glue or a liquid material that can be used for glue molding and can be cured by light. The workpiece 200 can be an object such as the front panel, back panel, glass module, etc. of an electronic product that needs to be formed by glue molding.
[0087] Please continue reading Figure 2 The molding device 100 includes a first mold 10 , a second mold 20 and a molding mold core 30 .
[0088] The first mold 10 and the second mold 20 are adapted to fit together, and the first mold 10 and the second mold 20 can clamp the workpiece 200 in the forming mold core 30. The forming mold core 30 is light-transmissive and is disposed between the first mold 10 and the second mold 20. The forming mold core 30 is used to accommodate the workpiece 200 and cooperates with the first mold 10 and the workpiece 200 to form a forming cavity 40. The forming cavity 40 is roughly similar in shape to the molded part 201 formed by the workpiece 200. The forming cavity 40 is used to accommodate the adhesive so that the adhesive is connected to the workpiece 200 after curing to form the molded part 201 of the workpiece 200. Among them, the second mold 20 is provided with a light-transmissive area 21 corresponding to the forming cavity 40. The light-transmissive area 21 is used to transmit light so that light promotes the curing of the adhesive, thereby allowing the adhesive to cure quickly and reducing the curing time of the adhesive.
[0089] An implementation process of the molding device 100 provided in some embodiments generally proceeds as follows: First, the molding core 30 is placed on the second mold 20 such that the molding core 30 and the light-transmitting area 21 of the second mold 20 are approximately aligned. That is, light passing through the light-transmitting area 21 can illuminate the molding core 30. Then, the workpiece 200 is placed on the molding core 30. Next, the first mold 10 and the second mold 20 are joined together to secure the workpiece 200 to the molding core 30. After the first mold 10 and the second mold 20 are joined together, the first mold 10, the workpiece 200, and the molding core 30 cooperate to form a molding cavity 40 for accommodating the adhesive. Then, the adhesive is injected into the molding cavity 40. Next, light is emitted from a light source, passing through the light-transmitting area 21 and the molding core 30 to illuminate the adhesive within the molding cavity 40. The adhesive rapidly solidifies under the illumination of the light and, after solidification, is bonded to the workpiece 200 to form the product. Next, the light source is turned off or the molding device 100 is moved away from the light source, and the first mold 10 and the second mold 20 are demolded. After demolding, the product is removed and can be processed as needed. In this way, the molding part 201 is connected to the workpiece 200 by glue injection molding.
[0090] It should be noted that in the embodiment of the present application, not all of the rubber material within the molding cavity 40 is used to solidify and form the molded part 201 of the workpiece 200. The rubber material within a portion of the molding cavity 40 is solidified and formed into the molded part 201 of the workpiece 200, and the shape of this portion of the cavity is similar to that of the molded part 201 of the workpiece 200; the remaining portion of the cavity is used to guide the rubber material so that the rubber material can flow into this portion of the cavity. The embodiment of the present application does not limit the shape of the molding cavity 40, and the shape of the molding cavity 40 can be designed according to actual needs.
[0091] In some embodiments, the light-transmitting area 21 may be a light-transmitting hole, a ring-shaped light-transmitting sheet, or a combination of a light-transmitting hole and a light-transmitting sheet. The combination of a light-transmitting hole and a light-transmitting sheet may be understood as a light-transmitting hole being formed on the light-transmitting sheet.
[0092] In some embodiments, the molding mold core 30 can be a silicone part. The silicone part has a high light transmittance, light can easily pass through the silicone part, and the utilization rate of light is high. The performance stability of the silicone part is high. After the silicone part is exposed to light, the chemical properties and physical and mechanical properties change very little with temperature. The silicone part is easy to mold, the material is easy to obtain, easy to process and shape, and reduces manufacturing costs. The silicone part is also not easy to damage the outer surface of the workpiece 200, which is beneficial to protecting the outer surface of the workpiece 200. The silicone part is also easy to separate from the cured rubber phase, which is beneficial to demolding the workpiece 200. Among them, the material of the silicone part can be 4-methylpentene (TPX, 4-methylpentene-1), cycloolefin copolymer (COC, copolymers of cycloolefin), etc.
[0093] It is understandable that in other embodiments, the forming mold core 30 can also be a glass object with high light transmittance, wherein the glass can be single-element glass, organic glass or inorganic glass, preferably quartz glass among inorganic glass.
[0094] In some embodiments, the molding device 100 further includes a light guide 50 , which is disposed between the molding mold core 30 and the light-transmitting area 21 . The light guide 50 is used to guide light passing through the light-transmitting area 21 so that the light can better and more evenly illuminate the molding mold core 30 .
[0095] In some embodiments, the molding apparatus 100 further includes a clamping assembly 60. The clamping assembly 60 is rotatably connected to the second mold 20 to clamp and secure the first mold 10 in contact with the second mold 20. Thus, the clamping assembly 60 enables the first mold 10 and the second mold 20 to be tightly closed, facilitating the tight compression of the workpiece 200 against the molding core 30, thereby facilitating subsequent glue pouring, curing, and other processes.
[0096] See also Figure 3 In some embodiments, the second mold 20 includes a molding base 22 for supporting the molding core 30. The light-transmitting area 21 includes a first light-transmitting region 211.
[0097] The molding base 22 is connected to the molding core 30. The molding base 22 is used to support the molding core 30 and ensure the size of the molding core 30. The first light-transmitting area 211 is correspondingly provided on the molding base 22. Thus, through the molding base 22, the second mold 20 provides good support for the molding core 30, which prevents deformation of the molding core 30. This ensures that the molding cavity 40 does not change after the injection of the rubber material, which helps to ensure the precision of the molded part 201 after the rubber material is cured.
[0098] In some embodiments, the molding base 22 is made of glass, which has high light transmittance, allowing light to easily pass through it. The high hardness of the glass facilitates support for the molding core 30. The first light-transmitting region 211 includes a plurality of spaced light-transmitting holes evenly distributed across the molding base 22. This high light transmittance, achieved through the use of the multiple light-transmitting holes and the glass, ensures that more light passes through the molding base 22 and the first light-transmitting region 211, thereby increasing light utilization.
[0099] It is understood that in other embodiments, the molding base 22 may also be a translucent silicone member or a rigid metal or plastic member, such as mold steel, plastic steel, or the like. The multiple light-transmitting holes of the first light-transmitting region 211 are evenly distributed on the molding base 22. The first light-transmitting region 211 may also be a glass member disposed on the molding base 22, or a combination of a glass member and light-transmitting holes.
[0100] In some embodiments, the molding base 22 defines a molding groove 221 for accommodating the molding core 30. A first redundant hole 222 is defined at the bottom of the molding groove 221. The first redundant hole 222 is configured to accommodate the portion of the workpiece 200 protruding from the molding core 30, thereby enabling the workpiece 200 to be tightly coupled with the molding core 30 to form the molding cavity 40. Accordingly, a first light-transmitting region 211 is disposed at the bottom of the molding groove 221 and surrounds the first redundant hole 222. When the first light-transmitting region 211 includes multiple light-transmitting holes, the multiple light-transmitting holes extend through the bottom of the molding groove 221.
[0101] It is understandable that in other embodiments, when the light transmittance of the molding base 22 is good, the first redundant hole 222 may be omitted depending on the size and type of the workpiece 200 .
[0102] In some embodiments, when the molding base 22 is a fragile material such as a glass piece, the second mold 20 may further include a support base 23 that can accommodate the molding base 22. In this case, the light-transmitting area 21 also includes a second light-transmitting area 212 provided on the support base 23 corresponding to the first light-transmitting area 211. The support base 23 is used to accommodate the molding base 22 and support the molding base 22 and the molding mold core 30 to further support and ensure the size of the molding mold core 30 and the molding quality. The second light-transmitting area 212 may include a plurality of light-transmitting holes arranged at intervals, and the plurality of light-transmitting holes are evenly provided on the support base 23. In this way, by supporting the molding base 22 through the support base 23, the molding base 22 can also be made less likely to break, thereby ensuring the stability of the molding device 100.
[0103] It is understandable that in other embodiments, the second light-transmitting area 212 may also be a glass member disposed on the support base 23 or a combination of a glass member and a light-transmitting hole.
[0104] In some embodiments, the support base 23 can be a rigid metal or plastic component, such as mold steel or plastic steel. The support base 23 defines a support groove 231 for accommodating the molding base 22. A second redundant hole 232 is defined at the bottom of the support groove 231. The second redundant hole 232 communicates with and cooperates with the first redundant hole 222 to accommodate the portion of the workpiece 200 protruding from the molding core 30, thereby enabling the workpiece 200 to tightly engage with the molding core 30 to form the molding cavity 40. Accordingly, a second light-transmitting region 212 is disposed at the bottom of the support groove 231 and surrounds the second redundant hole 232. If the second light-transmitting region 212 also includes multiple light-transmitting holes, the multiple light-transmitting holes extend through the bottom of the support groove 231. In this manner, the support base 23 is a rigid plastic component that supports the molding base 22, protecting it from breakage and reducing the weight of the molding device 100.
[0105] It is understood that in other embodiments, the molding base 22 may also be a rigid metal or plastic member. When the molding base 22 is a rigid metal or plastic member, the support base 23 may be omitted. When the molding base 22 is a glass member, the support base 23 may also be omitted by appropriately selecting the material of the molding base 22 and properly configuring the molding base 22.
[0106] In some embodiments, the second mold 20 further includes a base 24 and a curing light source 25 .
[0107] The base 24 is adapted to fit the first mold 10 and is used to accommodate the molding base 22 or the support base 23. A curing light source 25 is disposed between the base 24 and the molding base 22 or between the base 24 and the support base 23. The curing light source 25 corresponds to the first light-transmitting area 211 or the second light-transmitting area 212 and is used to emit light that promotes the curing of the adhesive.
[0108] In some embodiments, a receiving groove 241 is provided on the side of the base 24 facing the first mold 10, and the receiving groove 241 is used to accommodate the support base 23. The curing light source 25 is provided between the bottom of the receiving groove 241 and the support base 23, and the light emitted by the curing light source 25 corresponds to the second light-transmitting area 212. The curing light source 25 is connected to the bottom of the receiving groove 241, and the curing light source 25 and the support base 23 may be connected or not connected. The curing light source 25 may be an ultraviolet light source, and the curing light source 25 is used to emit ultraviolet light. In this way, the ultraviolet light emitted by the curing light source 25 passes through the second light-transmitting area 212 and the first light-transmitting area 211 and then irradiates the molding core 30, and passes through the light-transmitting molding core 30 to irradiate the rubber in the molding cavity 40. The rubber is quickly cured and formed under the irradiation of ultraviolet light, thereby reducing the curing time of the rubber.
[0109] It is understood that when the curing light source 25 includes multiple light sources, such as multiple lamp beads, the curing light source 25 can be connected to the support base 23, and the multiple light sources of the curing light source 25 are respectively arranged to correspond to the multiple light-transmitting holes of the second light-transmitting area 212 of the support base 23. In this way, the utilization rate of the light emitted by the curing light source 25 is increased.
[0110] It is understandable that in other embodiments, the curing light source 25 may also be a visible light source or other light source corresponding to the injected photosensitive adhesive. The curing light source 25 is used to emit light to promote rapid curing of the adhesive.
[0111] It is understandable that in other embodiments, the curing light source 25 can also be provided independently of the second mold 20. Exemplarily, the curing light source 25 is provided outside the second mold 20. The second mold 20 includes a molding base 22 and a support base 23. The molding base 22 is provided with a first light-transmitting area 211, and the support base 23 is provided with a second light-transmitting area 212. The first light-transmitting area 211 and the second light-transmitting area 212 can be understood as the light-transmitting area 21. The curing light source 25 is provided corresponding to the second light-transmitting area 212 of the support base 23. The light emitted by the curing light source 25 passes through the second light-transmitting area 212 on the support base 23 of the second mold 20 and the first light-transmitting area 211 on the molding base 22 to irradiate the molding core 30.
[0112] It is understandable that in some embodiments, the second mold 20 includes a molding base 22 and does not include a supporting base 23. The receiving groove 241 of the base 24 is used to accommodate the molding base 22. The curing light source 25 is arranged between the bottom of the receiving groove 241 and the molding base 22, and the light emitted by the curing light source 25 corresponds to the first light-transmitting area 211. The curing light source 25 is connected to the bottom of the receiving groove 241, and the curing light source 25 and the molding base 22 can be connected or not connected. The curing light source 25 is used to emit ultraviolet rays. In this way, the ultraviolet rays emitted by the curing light source 25 pass through the first light-transmitting area 211 and irradiate the molding mold core 30, and pass through the light-transmitting molding mold core 30 to irradiate the rubber in the molding cavity 40. The rubber is quickly cured and molded under the irradiation of ultraviolet rays, thereby reducing the curing time of the rubber.
[0113] It is understood that when the curing light source 25 includes multiple light sources, such as multiple lamp beads, the curing light source 25 can be connected to the molding base 22, and the multiple light sources of the curing light source 25 are respectively arranged to correspond to the multiple light-transmitting holes of the first light-transmitting area 211 of the molding base 22. In this way, the utilization rate of the light emitted by the curing light source 25 is high.
[0114] It is understood that in other embodiments, the curing light source 25 can also be provided independently of the second mold 20. For example, the curing light source 25 is provided outside the second mold 20. The second mold 20 includes a molding base 22, which is provided with a first light-transmitting area 211. The first light-transmitting area 211 can also be understood as the light-transmitting region 21. The curing light source 25 is provided corresponding to the first light-transmitting area 211 of the molding base 22. The light emitted by the curing light source 25 passes through the first light-transmitting area 211 on the molding base 22 of the second mold 20 to irradiate the molding core 30.
[0115] In some embodiments, the light-transmitting region 21 may include at least one of a light-transmitting hole and a light-transmitting sheet. For example, the light-transmitting region 21 includes a plurality of light-transmitting holes, which may be understood as light-transmitting holes in the first light-transmitting region 211 and / or the second light-transmitting region 212. The light-transmitting region 21 includes a light-transmitting sheet, which may be a glass sheet disposed on the molding base 22 or the support base. The light-transmitting sheet may also be independent of the molding base 22 and the support base 23 and disposed opposite the curing light source 25. For example, the glass sheet may be disposed between the molding base 22 and the molding mold core 30.
[0116] In some embodiments, the base 24 is further provided with at least two adjustment slots 242 on the side facing the first mold 10. The at least two adjustment slots 242 are located on one long side and one short side of the base 24, respectively. Matching adjustment members 243 are disposed within the adjustment slots 242. Thus, the adjustment members 243 and the adjustment slots 242 facilitate assembly of the molding base 22 or the support base 23, and facilitate pressing the molding base 22 or the support base 23 into the receiving slot 241 of the base 24 from two adjacent side surfaces of the molding base 22 or the support base 23, thereby facilitating assembly of the second mold 20.
[0117] See also Figure 4 In some embodiments, the light guide 50 is a frame-like structure, disposed between the mold core 30 and the light-transmitting region 21 . The light guide 50 is used to transmit and evenly distribute light. Thus, by providing the light guide 50 , light passing through the light-transmitting region 21 is irradiated by the light guide 50 , which processes the light so that it can better illuminate the mold core 30 . By providing the light guide 50 as a frame-like structure, the portion of the workpiece 200 protruding from the mold core 30 can also extend into the first redundant hole 222 and the second redundant hole 232 , thereby preventing interference between the light guide 50 and the workpiece 200 .
[0118] In some embodiments, the light guide 50 is an integrated frame-shaped quartz glass member. It is understandable that the glass member can also be an optical element such as a lens or a diffuser. After the light is optically modulated by the glass member, it can be uniformly irradiated onto the forming mold core 30. The embodiment of the present application defines "uniform light" as follows: after the light passes through the light-transmitting holes in the light-transmitting area 21, the light at each light-transmitting hole can be understood as the light emitted by a "point light source". The light emitted by multiple point light sources cannot fully irradiate the forming mold core 30. After the light emitted by the point light source is optically adjusted by the glass member, the light guide 50 can change the divergence angle of the light, so that the light can be evenly irradiated onto the forming mold core 30.
[0119] It is understood that in other embodiments, the light guide 50 can also be a one-piece frame-shaped silicone member. The light guide 50 can also be a segmented glass member or a segmented silicone member. When the light guide 50 is a segmented glass member or a segmented silicone member, the segmented glass member or segmented silicone member should cover the corresponding light-transmitting holes to optically modulate the light. It is understood that the light guide 50 can be a single glass member or silicone member, or it can be an assembled and connected member of glass and silicone members.
[0120] In some embodiments, the molding mold core 30 is a frame-shaped structure. The molding mold core 30 is provided with a frame-shaped glue guide groove 31. The embodiment of the present application defines the groove wall of the glue guide groove 31 close to the center of the molding mold core 30 as the inner groove wall, and the outer groove wall corresponding to the inner groove wall. Obviously, this is not a limitation of the embodiment of the present application. The bottom of the glue guide groove 31 is provided with a glue inlet hole 32 and a glue outlet hole 33. The glue inlet hole 32 is used to inject the glue into the glue guide groove 31, and the glue guide groove 31 guides the glue into the molding cavity 40. The glue outlet hole 33 is used to allow the excess glue to flow out when the glue in the molding cavity 40 is full. A plurality of glue flow grooves 34 are provided on the inner groove wall of the glue guide groove 31. The plurality of glue flow grooves 34 are all connected to the molding cavity 40. The glue flow grooves 34 are used to allow the glue in the glue guide groove 31 to flow into the molding cavity 40. Among them, the number of the glue inlet hole 32 and the glue outlet hole 33 are both two.
[0121] It can be understood that in some embodiments, the frame-shaped glue guide groove 31 can also be understood as a part of the molding cavity 40. After the glue in the glue guide groove 31 is solidified and formed, it is connected with the workpiece 200 to form a molded part 201. The formed molded part 201 can also be a frame-shaped structure surrounding the workpiece 200.
[0122] It is understood that in other embodiments, the number of the glue inlet holes 32 and the glue outlet holes 33 can be one, three, or more. The number of the glue inlet holes 32 and the glue outlet holes 33 can be equal or unequal. For example, the number of the glue inlet holes 32 can be two, and the number of the glue outlet holes 33 can be one.
[0123] Please also refer to Figure 3 and Figure 5 In some embodiments, the second mold 20 is provided with injection holes 244 communicating with the molding cavity 40 and used for injecting glue. The number of the injection holes 244 is equal to the number of the glue inlet holes 32. Thus, glue is injected into the molding cavity 40 through the injection holes 244.
[0124] In some embodiments, the base 24 of the second mold 20 is provided with two glue injection holes 244, the same number as the glue inlet holes 32, and two glue overflow holes 245, the same number as the glue outlet holes 33. The glue injection holes 244 are connected to the glue inlet holes 32 via a glue injection tube 26, and the glue overflow holes 245 are connected to the glue outlet holes 33 via a glue overflow tube 27. The glue injection tube 26 and the glue overflow tube 27 are both cylindrical. The glue injection tube 26 and the glue overflow tube 27 can be connected to the glue inlet holes 32 and the glue outlet holes 33, respectively, by passing through the curing light source 25, the support base 23, the molding base 22, and the light guide 50 between the base 24 and the molding mold core 30. The glue injection tube 26 and the glue overflow tube 27 can also be connected to the molding base 22 after passing through the curing light source 25 and the support base 23, and then connected to the molding base 22. Holes for glue injection and glue overflow are provided on the molding base 22 and the light guide 50 to connect to the glue inlet holes 32 and the glue outlet holes 33, respectively. In this way, the molding device 100 can inject glue from the glue injection hole 244 of the base 24 into the glue guide groove 31 of the molding core 30 through the glue injection pipe 26 and the glue overflow pipe 27, thereby allowing the glue to flow into the molding cavity 40. When glue flows out of the glue overflow hole 245 of the base 24, it indicates that the glue in the molding cavity 40 is full and the injection of glue into the molding cavity 40 can be stopped. After stopping the injection of glue into the molding cavity 40, plugs can be placed at the glue injection hole 244 and the glue overflow hole 245 to prevent the glue from overflowing through the glue injection hole 244 and the glue overflow hole 245.
[0125] It is understood that in other embodiments, the glue injection tube 26 and the glue overflow tube 27 can also be bent into a cylindrical shape, and the glue injection tube 26 and the glue overflow tube 27 can be bent to pass through the curing light source 25, the support base 23, the molding base 22, and the light guide 50 between the base 24 and the molding mold core 30. In this way, the integrity of the curing light source 25, the support base 23, the molding base 22, and the light guide 50 is avoided.
[0126] It can be understood that in some embodiments, the second mold 20 does not include the support base 23. When the glue injection tube 26 and the glue overflow tube 27 pass through the curing light source 25 and are connected to the molding base 22, the glue injection tube 26 and the glue overflow tube 27 also have the function of supporting the molding base 22, so that there is a space between the molding base 22 and the base 24 for accommodating the curing light source 25, which can provide heat dissipation and installation space for the curing light source 25, which is beneficial to improving the service life of the curing light source 25.
[0127] Please also refer to Figure 6 and Figure 7In some embodiments, the workpiece 200 can be pressed against the forming mold core 30 when the first mold 10 and the second mold 20 are closed. The first mold 10 includes a first plate 11, a second plate 12, and at least one connector 13. The first plate 11 and the second plate 12 are both generally plate-shaped and connected by at least one connector 13. Thus, the first plate 11 and the second plate 12 are connected by the connector 13, so that the second plate 12 can press the workpiece 200 against the forming mold core 30. The second plate 12 can be elastic, or made of a flexible material, or a portion of the second plate 12 can be made of a flexible material, to prevent damage to the workpiece 200 when pressed against the forming mold core 30. The connector 13 can be elastic, thereby creating an elastic connection between the first plate 11 and the second plate 12, allowing the workpiece 200 to be elastically pressed against the forming mold core 30 when the first mold 10 and the second mold 20 are closed.
[0128] Specifically, a receiving groove 111 is defined on one side of the first plate 11 near the second plate 12. The receiving groove 111 is configured to accommodate the second plate 12. The bottom of the receiving groove 111 of the first plate 11 is defined by a number of first connecting holes 112, equal to the number of connecting members 13. The second plate 12 is defined by a number of second connecting holes 121 corresponding to the first connecting holes 112. The second connecting holes 121 may be stepped holes. The connecting members 13 may be in the shape of a stepped column, with one end of the connecting member 13 being fixedly positioned within the first connecting hole 112 and the other end being movably positioned within the second connecting hole 121. The connecting member 13 is retained within the second connecting hole 121 by a stepped structure. Thus, the movable connection between the connecting member 13 and the second connecting hole 121 allows the first plate 11 and the second plate 12 to be movably connected without separation. The number of first connecting holes 112, second connecting holes 121, and connecting members 13 may be four.
[0129] An implementation process of the first mold 10 provided in some embodiments is roughly as follows: after placing the workpiece 200 on the forming mold core 30, the first mold 10 and the second mold 20 are adaptively clamped. During the clamping process, the second plate 12 contacts the workpiece 200, and the workpiece 200 forces the second plate 12 to move toward the first plate 11. The second plate 12 generates elastic force in the process of moving toward the first plate 11. After the first mold 10 and the second mold 20 are clamped, the position of the first plate 11 is relatively fixed. The second plate 12 presses the workpiece 200 tightly against the forming mold core 30 under the elastic action of the connecting member 13. In this way, the workpiece 200 can be tightly pressed against the forming mold core 30, and the molding cavity 40 formed by the workpiece 200, the first mold 10, and the forming mold core 30 meets the requirements of glue filling.
[0130] It is understandable that in other embodiments, the number of the first connection hole 112 , the second connection hole 121 and the connection member 13 may be one, two, three, five or more.
[0131] In some embodiments, the first connection hole 112 is a blind hole, thereby preventing impurities such as dust from entering the interior of the first mold 10 and the second mold 20 through the first connection hole 112 and contaminating the rubber material.
[0132] In some embodiments, at least one guide hole 113 is formed on the first plate 11. Figure 3 The side of the base 24 facing the first plate 11 is provided with guide posts 28 that mate with the guide holes 113. The guide posts 28 are generally truncated cone-shaped. There are four guide holes 113 and four guide posts 28. This coordination between the guide holes 113 and the guide posts 28 facilitates precise assembly of the first and second molds 10, 20.
[0133] It is understandable that in other embodiments, the number of guide holes 113 and guide posts 28 can also be one, two, three, five or more.
[0134] See also Figure 8 In some embodiments, the clamping assembly 60 of the molding device 100 includes two pairs of rotating members 61 and a pair of bodies 62. The two pairs of rotating members 61 are rotatably connected to opposite sides of the base 24 via rotating shafts 67, and one body 62 is connected to the two rotating members 61 on one side of the base 24. The body 62 is provided with a plurality of stop grooves 621 on a side away from the rotating members 61. In the embodiment of the present application, the number of stop grooves 621 on a body 62 can be three. The embodiment of the present application uses one stop groove 621 and the corresponding parts on the stop groove 621 as an example for detailed description.
[0135] It is understandable that in other embodiments, the rotating members 61 may be one, three or more pairs. The number of the stop grooves 621 on a body 62 may be one, two, four or more, which may be set according to actual needs.
[0136] The clamping assembly 60 also includes a number of stoppers 63 equal to the number of the stop grooves 621. The stoppers 63 are roughly plate-shaped and are fixed in the stop grooves 621 by fasteners 66 such as bolts. Two through holes 622 are provided at the bottom of each stop groove 621, and the through holes 622 pass through the body 62. A second elastic member 64 and a pressing member 65 are respectively provided in the two through holes 622. The pressing member 65 is movably provided in the through hole 622, one end of the second elastic member 64 is connected to the stopper 63, and the other end of the second elastic member 64 is connected to the pressing member 65. In this way, the second elastic member 64 is stopped by the stopper 63, and the second elastic member 64 is elastically connected to the pressing member 65, so that the pressing member 65 can elastically abut against the first mold 10.
[0137] It is understandable that in other embodiments, the bottom of each stop groove 621 may further have one, three, four or more through holes 622 . The multiple stop grooves 621 on one body 62 may also be interconnected to form one stop groove 621 .
[0138] In some embodiments, the through hole 622 may be a stepped hole, and the pressing member 65 is adapted to fit within the through hole 622. The pressing member 65 is provided with a mounting groove 651 connected to the second elastic member 64. The other end of the second elastic member 64 abuts against the bottom of the mounting groove 651, and the pressing member 65 is movably stopped within the through hole 622 by the cooperation of the stepped portion. In this manner, the second elastic member 64 need not be fixedly connected to the stopper 63 and the pressing member 65. When assembling the pressing member 65 and the second elastic member 64, the pressing member 65 is first placed within the through hole 622, and then the second elastic member 64 is placed within the mounting groove 651 of the pressing member 65. Finally, the stopper 63 is mounted within the stopper groove 621 via the fastener 66. This allows for simple installation and ease of assembly of the clamping assembly 60.
[0139] In some embodiments, one end of the pressing member 65 protruding from the through hole 622 is an arcuate surface 652, and the first plate 11 of the first mold 10 is provided with an arcuate groove 114 adapted to the arcuate surface 652 of the pressing member 65 on the side facing away from the second plate 12 (see Figure 6 Thus, through the cooperation between the arc surface 652 and the arc groove 114 , the pressing member 65 can easily slide into the arc groove 114 , so that the clamping assembly 60 can press the first mold 10 against the second mold 20 after rotation.
[0140] The clamping assembly 60 provided in some embodiments generally follows the following steps: After closing the first mold 10 and the second mold 20, the pair of bodies 62 are gripped, causing the bodies 62 to drive the rotating member 61 to rotate about the base 24 of the second mold 20. The bodies 62 then drive the stopper 63 and other components to rotate toward the first plate 11 of the first mold 10. When the curved surface 652 of the pressing member 65 contacts the surface of the first plate 11, the pressing member 65 is obstructed by the first plate 11 and moves toward the stopper 63. During this movement, the pressing member 65 compresses the second elastic member 64, which generates an elastic force. When the curved surface 652 of the pressing member 65 slides into the curved groove 114, the pressing member 65 compresses the first plate 11 under the elastic force of the second elastic member 64. Thus, through the cooperation between the pressing member 65 and the second elastic member 64, the clamping assembly 60 compresses the first mold 10 against the second mold 20.
[0141] An implementation process of the molding device 100 provided in some embodiments is roughly as follows: First, the second mold 20 is placed on a machine table. Then, the molding mold core 30 is placed on the molding base 22. Next, the workpiece 200 is placed on the molding mold core 30. Next, the first mold 10 and the second mold 20 are clamped. Next, the clamping assembly 60 is rotated so that the clamping assembly 60 completes the clamping of the first mold 10 and the second mold 20, and the first mold 10 uses elastic force to tightly press the workpiece 200 against the molding mold core 30. Next, glue is injected into the molding cavity 40 through the glue injection hole 244 of the base 24 until glue flows out of the glue overflow hole 245, and the glue injection is stopped. Next, the curing light source 25 is controlled to light up so that the curing light source 25 emits ultraviolet light, and the ultraviolet light passes through the first light-transmitting area 211 of the molding base 22 and the light guide 50 to irradiate the glue in the molding cavity 40. Next, after curing light source 25 irradiates the adhesive for a predetermined time, curing light source 25 is controlled to be extinguished. Next, clamping assembly 60 is rotated to release first mold 10 and second mold 20. Next, first mold 10 is removed, and workpiece 200, connected to the cured adhesive, is removed. This completes the process of potting and molding molded part 201 connected to workpiece 200.
[0142] The molding device 100 provided in the embodiment of the present application tightly accommodates the workpiece 200 on the molding mold core 30 through the cooperation of the clamping assembly 60, the first mold 10 and the second mold 20, so that the molding cavity 40 formed by the workpiece 200, the first mold 10 and the molding mold core 30 meets the glue injection requirements, and the formed molded part 201 has high precision. After the workpiece 200 is placed on the molding mold core 30, glue is injected into the molding cavity 40 through the glue injection hole 244 of the base 24. Whether the glue injection is completed is determined by observing whether there is glue flowing out of the overflow glue hole 245, so as to prevent excessive glue injection from damaging the molding mold core 30, avoiding waste of glue and damaging the molding device 100. After the glue injection is completed, ultraviolet light or visible light is emitted by the curing light source 25, so that the light passes through the light-transmitting area 21, the light guide 50 and the molding mold core 30 to irradiate the glue in the molding cavity 40, so that the glue can be quickly cured under the irradiation of light, reducing the time for the glue to cure, improving the efficiency of the glue curing, and reducing the overall manufacturing cost.
