[0047] Currently, the louver assembly of the air conditioner indoor unit consists of a connecting rod and multiple louvers. To complete this louver assembly, during the production of the louver assembly, the air guide strip and the connecting component need to be injection-molded separately first. After the injection molding is completed, the air guide strip and the connecting component are manually assembled into the louver assembly. Through traditional manual assembly, the production efficiency is very low and it is easy to cause product scrapping due to operations. Even when assembled with a special assembly jig, there are also problems such as the secondary turnover after product injection molding and the high cost of investing in the assembly jig.

[0048] The present utility model proposes an in-mold assembly system 100.

[0049] Please refer to Figures 1 to 15 , in an embodiment of the present utility model, the in-mold assembly system 100 includes a stationary mold mechanism 10, a moving mold mechanism 20, and an assembly mechanism 30. The stationary mold mechanism 10 includes a stationary mold core 11; the moving mold mechanism 20 is disposed opposite to the stationary mold mechanism 10. The moving mold mechanism 20 includes a sliding assembly 21, a moving mold core 22, and a discharging assembly 23. The sliding assembly 21 is used to cooperate with the moving mold core 22 to inject a first injection molded part 200. The discharging assembly 23 is used to cooperate with the stationary mold core 11 to inject a second injection molded part 300. The sliding assembly 21 has an injection position suitable for injecting the first injection molded part 200 and an assembly position suitable for assembling the first injection molded part 200 with the second injection molded part 300. The sliding assembly 21 includes a positioning member 212, and the positioning member 212 is used to position the first injection molded part 200 on the sliding assembly 21. The assembly mechanism 30 is drivingly connected to the sliding assembly 21. The assembly mechanism 30 is used to drive the positioning member 212 to move towards the discharging assembly 23 when the sliding assembly 21 is in the assembly position, so as to dock the first injection molded part 200 with the second injection molded part 300 to form an assembled part.

[0050] When the static mold mechanism 10 and the moving mold mechanism 20 are in the mold closing state, the sliding component 21 is in the injection position to cooperate with the moving mold core 22 to form a first injection position, and the static mold core 11 and the discharging component 23 cooperate to form a second injection position;

[0051] When the static mold mechanism 10 and the moving mold mechanism 20 are in the mold opening state, the assembling mechanism 30 is further configured to drive the sliding component 21 to move from the injection position to the assembling position.

[0052] In the present utility model, the sliding component 21 further has a discharging position which is relatively spaced from the moving mold core 22. The discharging position and the assembling position are located on the side of the injection position close to the static mold mechanism 10. The assembling mechanism 30 is disposed on the moving mold mechanism 20. When the static mold mechanism 10 and the moving mold mechanism 20 are in the mold opening state, the assembling mechanism 30 is configured to drive the sliding component 21 to move from the injection position to the discharging position along a first direction, and then move from the discharging position to the assembling position along a second direction. The first direction intersects with the second direction. The first direction can be vertical and the second direction can be horizontal. The first injection part 200 can be a connecting rod, and the second injection part 300 can be a louver. The in-mold assembling system 100 can further include a hot runner component 50 disposed on the static mold mechanism 10. In the present utility model, the static mold mechanism 10 can be disposed above the moving mold mechanism 20. Among them, the static mold core 11 is disposed above the discharging component 23, the sliding component 21 is disposed above the moving mold core 22, and the sliding component 21 is disposed below the static mold core 11. When performing the injection operation of the first injection part 200 and the second injection part 300, the static mold mechanism 10 and the moving mold mechanism 20 are closed, so that the moving mold core 22 and the sliding component 21 are closed to form a first injection position, and the static mold core 11 and the discharging component 23 are closed to form a second injection position. At this time, the hot runner component 50 is connected to the first injection position and the second injection position to perform the injection molding of the connecting rod and the louver. After the injection molding, the moving mold mechanism 20 and the static mold mechanism 10 are opened. The connecting rod remains in the first injection position formed by the engagement of the moving mold core 22 and the sliding component 21. The static mold core 11 is separated from the discharging component 23, and the louver remains in the discharging component 23. Since the hot runner component 50 is disposed on the static mold mechanism 10, at this time, the hot runner component 50 is separated from the first injection position and the second injection position. Then, the assembling mechanism 30 is used to drive the sliding component 21 to move, from the injection position to the discharging position, so that the connecting rod is exposed and remains on the sliding component 21. At this time, the assembling mechanism 30 can be further used to drive the sliding component 21 to translate to the assembling position, so that the first mounting position 201 on the connecting rod is aligned with the second mounting position 301 on the louver. Then, by driving the connecting rod to move downward, the connecting rod moves toward the louver and is inserted and connected with the louver to realize the assembly of the connecting rod and the louver.

[0053] When moving the first injection molded part 200 towards the second injection molded part 300, it is possible that the first mounting position 201 can be engaged with the second mounting position 301 to achieve the assembly of the first injection molded part 200 and the second injection molded part 300. For example, when the first injection molded part 200 is a connecting rod and the second injection molded part 300 is a louver, the first mounting position 201 is a mounting hole and the second mounting position 301 is a clamping protrusion. When assembling the connecting rod and the louver, the clamping protrusion is inserted into the mounting hole and is rotationally connected with the mounting hole in cooperation, so that there is a movable connection feature between the first injection molded part 200 and the second injection molded part 300 after assembly.

[0054] Among them, the positioning member 212 can be set as multiple guide rods, and the multiple guide rods are movably arranged on the sliding assembly 21. When the first injection molded part 200 is a connecting rod, the multiple guide rods can be distributed at intervals along the length direction of the connecting rod. When injecting the connecting rod, the guide rods can participate in the molding of the connecting rod, and a positioning portion 202 can be formed on the surface of the guide rod facing the sliding assembly 21. The positioning portion 202 can be a concave pit or a circular ring protrusion. When the sliding assembly 21 is separated from the moving die core 22, the guide rods can stay on the sliding assembly 21 through the positioning cooperation with the positioning member 212. When the sliding assembly is in the assembled position, the guide rods can be driven by the assembling mechanism 30 to move towards the discharging assembly 23, and the connecting rod positioned on the positioning member 212 can be accurately moved to the position for docking and installing with the louver, so as to meet the high-precision in-mold assembly operation of multiple parts.

[0055] The technical solution of the present utility model sets a static mold mechanism 10 including a static mold core 11, and sets a moving mold mechanism 20 including a sliding assembly 21, a moving mold core 22 and a discharging assembly 23. When the static mold mechanism 10 and the moving mold mechanism 20 are clamped, the first injection molded part 200 can be injected through the first injection position formed by the cooperation of the sliding assembly 21 and the moving mold core 22, and the second injection molded part 300 can be injected through the second injection position formed by the cooperation of the discharging assembly 23 and the static mold core 11. When the static mold mechanism 10 and the moving mold mechanism 20 are opened and the static mold core 11 is separated from the discharging assembly 23, the sliding assembly 21 is driven by the assembling mechanism 30 to move to the assembled position. Thus, when the sliding assembly 21 is in the assembled position, the positioning member 212 is driven by the assembling mechanism 30 to drive the first injection molded part 200 to approach the second injection molded part 300 for docking and assembly, realizing the injection operation of two injection molded parts simultaneously in the mold, and realizing the high-precision docking and assembly operation of two injection molded parts in the mold, improving the overall production efficiency of plastic part products.

[0056] In the present utility model, one or more first injection stations may be provided. Multiple groups of second injection stations may be provided, and each group of second injection stations is provided corresponding to one first injection station. Multiple second injection positions may be provided for each group of injection stations to perform the injection operation of multiple second injection parts 300. When performing the assembly operation of the first injection part and the second injection parts 300 subsequently, by moving the first injection part, a single first injection part can be assembled with a group of multiple second injection parts, improving the in-mold assembly efficiency.

[0057] Referring to Figure 2 、 Figure 14 、 Figure 15 As shown, in an embodiment of the present utility model, the sliding assembly 21 further includes a slider 211. A first cavity 2111 is provided on a surface of the slider 211 facing away from the stationary mold mechanism 10. A second cavity 221 is provided on a surface of the moving mold core 22 facing the stationary mold mechanism 10. The first cavity 2111 and the second cavity 221 cooperate to form the first injection position.

[0058] With such a setting, part of the first injection position for injecting the first injection part 200 is arranged on the slider 211, and the other part is arranged on the moving mold core 22. After the mold is closed, at least part of the first injection part 200 can be accommodated in the first cavity 2111. Thus, when transferring the first injection part 200 through the sliding assembly 21, a certain positioning can be provided for the first injection part 200 to prevent the first injection part 200 from shifting. Of course, in other embodiments, a first cavity 2111 may also be provided on a surface of the slider 211 facing away from the stationary mold mechanism 10, and no second cavity 221 is provided on a surface of the moving mold core 22 facing the stationary mold mechanism 10. The moving mold core 22 only serves as the seal of the first cavity 2111, and the first injection position is only formed in the first cavity 2111. No specific limitation is made here.

[0059] Referring to Figure 7 、 Figure 8 、 Figure 10 As shown, in an embodiment of the present utility model, the positioning member 212 is arranged in the first cavity 2111. When the sliding assembly 21 is in the discharging position and the assembling position, the positioning member 212 is used to position the first injection part 200 in the first cavity 2111.

[0060] Among them, the positioning member 212 can be set as multiple guide rods. The multiple guide rods are movably arranged on the slider 211 and are spaced apart along the length direction of the first cavity 2111. When the first injection molded part 200 is injection molded, at least part of the guide rod is accommodated in the first cavity 2111 and is used to participate in the molding of the first injection molded part 200. After the first injection molded part 200 is molded, a positioning portion 202 that cooperates with the positioning member is formed on the surface of the first injection molded part 200 facing the slider 211. The positioning portion 202 can be a concave pit or a circular ring protrusion. One end of the guide rod is clamped in the positioning portion 202. When the sliding assembly 21 is separated from the moving die core 22, the first injection molded part 200 can be in closer contact with the sliding assembly 21, so that it can remain on the sliding assembly 21, facilitating the subsequent assembly mechanism 30 to drive the sliding assembly 21 to move and align the first injection molded part 200 with the second injection molded part 300.

[0061] Optionally, the positioning member 212 has a plug-in joint disposed in the first cavity 2111. The plug-in joint is used to be plugged into the positioning portion 202 of the first injection molded part 200 to position the first injection molded part 200 in the first cavity 2111. Among them, the plug-in joint can be provided with an uneven outer surface. When the first injection molded part 200 is molded, it can enable the positioning member 212 to increase the grasping force on the first injection molded part 200, so that the positioning effect of the positioning member 212 on the first injection molded part 200 is better.

[0062] In addition, the positioning member 212 can also be a protrusion disposed in the inner cavity of the first cavity 2111. When the first injection molded part 200 is injection molded, the protrusion is fitted into the first injection molded part 200. When the sliding assembly 21 is separated from the moving die core 22, it enables the first injection molded part 200 to be in closer contact with the sliding assembly 21, so that it can remain on the sliding assembly 21. No specific limitation is made here.

[0063] Refer to Figure 7 、 Figure 8 As described above, in the embodiment of the present utility model, the assembly mechanism 30 includes an ejection driving member 33. The ejection driving member 33 is disposed on the slider 211. The ejection driving member 33 is drivingly connected to the positioning member 212. When the sliding assembly 21 is in the discharging position, the ejection driving member 33 is used to drive the positioning member 212 to drive the first injection molded part 200 to move towards the second injection molded part 300 to dock and assemble the first injection molded part 200 and the second injection molded part 300.

[0064] In the above embodiment, the positioning member 212 can be set as a plurality of guide rods spaced along the length direction of the first cavity 2111. One end of the guide rod extends into the first cavity 2111, and the other end of the guide rod is connected to an ejection plate located above the slider 211. The ejection driving member 33 can be disposed on a sliding cover plate located above the ejection plate. When the sliding assembly 21 is aligned with the discharging assembly 23, the ejection driving member 33 drives the ejection plate to move downward, driving the plurality of guide rods to move downward simultaneously, ejecting the first injection molded part 200 located in the first cavity 2111, and causing the first injection molded part 200 to be docked with the second injection molded part 300, thereby realizing the assembly of the first injection molded part 200 and the second injection molded part 300.

[0065] Referring to Figure 2 、 Figure 4 As shown, in the embodiment of the present invention, the assembly mechanism 30 further includes a floating driving member 31 and a side ejection driving member 32. When the static mold mechanism 10 and the moving mold mechanism 20 are in an open mold state, the floating driving member 31 is used to drive the sliding assembly 21 to move away from the moving mold core 22 along a first direction, so that the sliding assembly 21 moves from an injection position to a discharging position, and the side ejection driving member 32 is used to drive the sliding assembly 21 to move closer to the discharging assembly 23 along a second direction, so that the sliding assembly 21 moves from the discharging position to an assembly position.

[0066] In the present invention, since both the sliding assembly 21 and the moving mold core 22 are disposed on the moving mold mechanism 20, when the moving mold mechanism 20 and the static mold mechanism 10 are separated, and the static mold core 11 and the discharging assembly 23 are separated, the sliding assembly 21 remains in the injection position. At this time, the floating driving member 31 can be used to drive the sliding assembly 21 to move upward to a discharging position spaced relatively from the moving mold core 22. The first injection molded part 200 moves with the sliding assembly 21 and is separated from the moving mold core 22, avoiding interference of the moving mold core 22 with the movement of the sliding assembly 21 when the first injection molded part 200 and the second injection molded part 300 are subsequently closed.

[0067] In addition, the side top driving member 32 can be arranged on the moving template 24. When the moving template 24 is driven by the floating driving member 31 to move upward away from the moving die backing plate 25, the sliding assembly 21 can be driven by the side top driving member 32 to translate on the moving template 24, so that the sliding assembly 21 moves to an assembling position which is arranged at a relative interval with the discharging assembly 23. Wherein, a through groove is formed through the moving template 24, and the discharging assembly 23 is located directly below the through groove. When the sliding assembly 21 is aligned with the discharging assembly 23, the first injection molded part 200 is aligned with the second injection molded part 300 through the above through groove. In addition, when the sliding assembly 21 is in the discharging position, there is an interval between the first injection molded part 200 and the moving template 24. When the sliding assembly 21 moves, the first injection molded part 200 will not interfere with the moving template 24, and the moving stability of the first injection molded part 200 can be maintained.

[0068] Referring to Figure 2 As shown, in the embodiment of the present utility model, the moving die mechanism 20 further includes a moving template 24 and a moving die backing plate 25. The sliding assembly 21 and the discharging assembly 23 are arranged on the moving template 24, the moving die core 22 is arranged on the moving die backing plate 25, and the floating driving member 31 is used to drive the moving template 24 to move away from the moving die backing plate 25, so that the sliding assembly 21 and the discharging assembly 23 move away from the moving die core 22.

[0069] With such an arrangement, the floating driving member 31 can be used to drive the moving template 24 to move upward relative to the moving die backing plate 25, and the sliding assembly 21 and the discharging assembly 23 arranged on the moving template 24 move upward synchronously. Not only can the sliding assembly 21 be separated from the moving die core 22, but also the same height difference can be always maintained between the sliding assembly 21 and the moving die core 22, and the situation that the sliding assembly 21 is too high above the moving die core 22 will not occur. Thus, when the ejecting driving member 33 and the positioning member 212 are arranged to move the first injection molded part 200 out of the slider 211 and dock and assemble it with the second injection molded part 300, the moving stroke of the first injection molded part 200 can be kept short, and the ejecting driving member 33 and the positioning member 212 do not need to be set with too large sizes, which is beneficial to saving the in-mold space.

[0070] Referring to Figure 11 、 Figure 12 As shown, in the embodiment of the present utility model, the discharging assembly 23 includes two obliquely ejecting members 231 arranged oppositely. The obliquely ejecting member 231 is provided with an injection part 2311. The injection parts 2311 of the two obliquely ejecting members 231 are spliced to form a third cavity. A fourth cavity is arranged on one surface of the static die core 11 facing the discharging assembly 23. The third cavity and the fourth cavity cooperate to form the second injection position.

[0071] Among them, the third cavity can be used to form the main structure of the second injection molded part 300, and the fourth cavity can be used to form the local structure of the second injection molded part 300. In this way, when the static mold core 11 and the discharge assembly 23 are separated, since the contact area between the second injection molded part 300 and the third cavity is larger, the second injection molded part 300 will be more likely to remain in the third cavity. When the static mold core 11 and the discharge assembly 23 are separated, the second injection molded part 300 can be ejected from the fourth cavity without the ejection structure, thereby solving the problem of space in the mold. And by setting the discharge assembly 23 as a splicing of the injection molding part 2311 of two oblique ejection parts 231, the third cavity can be opened, so that the third cavity can be opened by separating the two oblique ejection parts 231, and after the first injection molded part 200 and the second injection molded part 300 are assembled and formed, it is convenient to discharge the assembly.

[0072] In addition, when a third cavity is set up to form the main structure of the second injection molded part 300, since the contact area between the second injection molded part 300 and the third cavity is larger, when the first injection molded part 200 and the second injection molded part 300 are assembled, stable support and positioning can be provided for the second injection molded part 300 to prevent the second injection molded part 300 from shifting and causing assembly failure.

[0073] See also Figure 7 , Figure 11 As shown, further, the in-mold assembly system 100 also includes a mold ejector assembly 40, which is drivingly connected to the oblique ejector member 231. When the first injection molded part 200 and the second injection molded part 300 are assembled to form an assembly, the mold ejector assembly 40 is used to drive the two oblique ejector members 231 to separate from each other and move toward the static mold mechanism 10 to eject the assembly.

[0074] The mold ejection assembly 40 includes a movable mold ejection plate 42 and a movable mold ejection fixing plate 41. The movable mold ejection fixing plate 41 is arranged below the movable mold ejection plate 42 and is used to install the movable mold ejection plate 42. The oblique ejection member 231 also includes an oblique connection portion 2312, which is inclined from the injection portion 2311 toward the movable mold ejection plate 42, and the oblique connection portion 2312 is inclined toward the side of the oblique ejection member 231 away from the other oblique ejection member 231. The movable mold ejection plate 42 is used to drive the oblique ejection member 231 to move along the inclined direction of its oblique connection portion 2312. When both oblique ejection members 231 are driven to move by the movable mold ejection plate 42, the two oblique ejection members 231 will separate from each other, so that the third cavity opens obliquely upward. After the first injection molded part 200 and the second injection molded part 300 are assembled, the assembly can be ejected upward to realize the ejection and discharge of the assembly.

[0075] See also Figure 2 , Figure 3 , Figure 5As shown, in an embodiment of the present utility model, the static mold mechanism 10 further includes a static mold ejection assembly 12. The static mold ejection assembly 12 is disposed on a side of the static mold core 11 away from the discharge assembly 23. When the static mold mechanism 10 and the moving mold mechanism 20 are in an open mold state, the static mold ejection assembly 12 is used to eject the second injection molded part 300 into the third cavity.

[0076] Among them, the static mold ejection assembly 12 may include a static mold ejection driving member and a static mold ejector pin. The static mold ejection driving member is drivingly connected to the static mold ejector pin. When the static mold core 11 and the discharge assembly 23 are in an open mold state, the static mold ejection driving member drives the static mold ejector pin to move towards the second injection molded part 300, and moves the second injection molded part 300 out of the fourth cavity of the static mold core 11, thereby realizing the separation of the second injection molded part 300 from the static mold core 11 and avoiding the adhesion of the second injection molded part 300 to the static mold core 11, resulting in incomplete discharge of the second injection molded part 300.

[0077] Refer to Figure 2 、 Figure 5 、 Figure 6 In an embodiment of the present utility model, the moving mold mechanism 20 includes a plurality of discharge assemblies 23 arranged at intervals. The plurality of discharge assemblies 23 cooperate with the static mold core 11 to form a plurality of second injection positions. When the sliding assembly 21 is in the assembled position, the assembly mechanism 30 is used to dock the first injection molded part 200 with the plurality of second injection molded parts 300 to form an assembled part.

[0078] With such a setting, when the in-mold assembly system 100 performs injection molding, a plurality of second injection molded parts 300 can be formed by one injection molding. When performing in-mold assembly, a plurality of second injection molded parts 300 can be assembled on the first injection molded part 200 at one time. In the case where the first injection molded part 200 is a connecting rod and the second injection molded part 300 is a louver, the in-mold assembly efficiency of the product can be improved. Among them, the arrangement position and arrangement spacing of the second injection positions can be set according to the number and distribution position of the first mounting positions 201 on the first injection molded part 200. For example, if there are 12 first mounting positions 201 on the first injection molded part 200 and the 12 first mounting positions 201 are equally spaced, then 12 discharge assemblies 23 arranged at equal intervals can be set, corresponding to the 12 first mounting positions 201 one by one, so as to be able to simultaneously injection mold 12 corresponding second injection molded parts 300 and realize the simultaneous assembly of 12 second injection molded parts 300 on the 12 first mounting positions 201 of the first injection molded part 200.

[0079] Refer to Figure 2 、 Figure 5 、 Figure 7, in the embodiment of the present utility model, the moving die mechanism 20 includes two said sliding components 21 and two said moving die cores 22. The two said sliding components 21 and the two said moving die cores 22 are in one-to-one cooperation to form two said first injection positions.

[0080] With such a setting, two said first injection molded parts 200 can be injection molded simultaneously in the mold. When multiple second injection molded parts 300 can be injection molded simultaneously in the mold, when assembling the injection molded parts in the mold, the multiple second injection molded parts 300 can be divided into two groups, and the two first injection molded parts 200 are respectively docked and assembled with the two groups of second injection molded parts 300 to achieve the formation of two assembled parts in a single assembly. Or, the first injection molded part 200 after the first injection can be assembled with the second injection molded part 300 first, then the injection of the next group of second injection molded parts 300 is carried out, and then the other first injection molded part 200 is assembled with the next group of second injection molded parts 300. No specific limitation is made here.

Among them, multiple hot runner connecting pipes 52 can be provided, and the multiple hot runner connecting pipes 52 respectively correspond to the first injection position and the second injection position. When the stationary die mechanism 10 and the moving die mechanism 20 are closed, multiple hot runner connecting pipes 52 are respectively inserted into the first injection position and the second injection position to release high-temperature injection molding materials. When the stationary die mechanism 10 and the moving die mechanism 20 are separated, the multiple hot runner connecting pipes 52 move away from the moving die mechanism 20 with the movement of the moving die mechanism 20 and are separated from the first injection position and the second injection position.

[0083] When there are multiple second injection positions, the hot runner assembly 50 further includes a flow splitter 53. The flow splitter 53 is disposed within the stationary mold core 11. The flow splitter 53 has a plurality of output ends respectively connected to a plurality of third cavities.

When injecting a plurality of second injection parts 300, the flow splitter 53 splits the high-temperature injection material from the hot runner connecting pipe 52 to a plurality of second injection stations, realizing the simultaneous injection operation of a plurality of second injection parts 300.
