Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to a disassembly and assembly device for multiple sets of transition blocks. Background Technology

[0002] like Figure 1 The product shown includes a plastic body 110 and a metal terminal 120 disposed inside the plastic body. The metal terminal acts as a conductor, and the plastic body provides insulation for the metal terminal. This product is typically manufactured using injection molding. Before injection molding, the metal terminal is placed into the mold, and then the plastic body is formed around the metal terminal.

[0003] The aforementioned injection-molded body has a complex structure, and to meet demolding requirements, it typically requires at least three sliders with cores. More sliders mean that the sliding direction of each slider needs to be carefully considered during demolding to avoid situations where the sliders cannot open or close. Furthermore, since multiple sliders require multiple drive mechanisms to operate them individually, these combined factors can lead to an excessively large injection mold.

[0004] To address the aforementioned issues, the industry has developed a solution using transition blocks to replace the sliders connected to the mold. Specifically, multiple sliders that collectively form a specific cavity / core are designed to detach from the mold. Before molding, metal terminals are placed on the sliders outside the mold, and the multiple sliders are closed to form a single transition block. This transition block is then placed inside the mold. After the front and rear molds are closed, a pre-defined cavity is formed between the transition block and the molds. The injection molding machine performs injection molding, and then the mold is opened. The transition block and the molded product are removed from the mold. Outside the mold, the transition block is disassembled into multiple sliders, the product is removed, and then the multiple sliders are closed back into the transition block. This process is repeated. Using transition blocks can reduce (or even eliminate) the need for sliders and corresponding drive mechanisms within the mold. However, the assembly and disassembly of transition blocks are relatively cumbersome, and their efficiency is a significant factor affecting production cycle time. Therefore, improving the efficiency of transition block assembly and disassembly is a problem that those skilled in the art are continuously working to solve. Summary of the Invention

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0044] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0045] The disassembly and assembly device for multiple transition blocks in this embodiment can be used to simultaneously disassemble and assemble multiple transition blocks, greatly improving the efficiency of transition block disassembly and assembly. For example... Figure 4 As shown, the transition block in this embodiment includes slider A10, slider B20 and slider C30, and slider A10, slider B20 and slider C30 are connected in pairs.

[0046] like Figures 2 to 4As shown, the disassembly and assembly device of this embodiment mainly includes a frame and at least one disassembly and assembly component mounted on the frame. The disassembly and assembly component mainly includes: a first fixing plate 1, a first disassembly and assembly mechanism 3, a second disassembly and assembly mechanism 4, a third disassembly and assembly mechanism 5, a fourth disassembly and assembly mechanism 6, and a fifth disassembly and assembly mechanism 7. The first fixing plate 1 is connected to the frame and has a first station 11, a second station 12 adjacent to the first station 11 along the X direction, a third station 13 adjacent to the first station 11 along the Y direction, and a fourth station 14 adjacent to both the second station 12 and the third station 13. In other words, the first station 11, the second station 12, the third station 13, and the fourth station 14 are generally arranged in a "field" shape. The second station 12 is located on one side of the first station 11 along the X direction, the third station 13 is located on one side of the first station 11 along the Y direction, and the fourth station 14 is located diagonally opposite the first station 11. Each of the four workstations is equipped with a material rack 2 for supporting the material parts (products) formed by injection molds. The part of the material rack 2 that supports the material parts is contoured to the surface of the material parts. The two adjacent material racks 2 are arranged axially symmetrically. Therefore, the transition blocks on the two adjacent workstations are also axially symmetrical. Specifically, slider A10 on the first station 11 and the third station 13 is located on the side of these two stations away from the second station 12 and the fourth station 14, while slider A10 on the second station 12 and the fourth station 14 is located on the side of these two stations away from the first station 11 and the third station 13; slider B20 on the first station 11 and the second station 12 is located on the side of these two stations away from the third station 13 and the fourth station 14, while slider B20 on the third station 13 and the fourth station 14 is located on the side of these two stations away from the first station 11 and the second station 12; slider C30 on the first station 11 and the second station 12 is located on the side of these two stations facing the third station 13 and the fourth station 14, while slider C30 on the third station 13 and the fourth station 14 is located on the side of these two stations facing the first station 11 and the second station 12.

[0047] The first disassembly / assembly mechanism 3 is mounted on the frame and is used to disassemble and assemble slider A10 on the first station 11 and the third station 13 along the X direction. The second disassembly / assembly mechanism 4 is mounted on the frame and is used to disassemble and assemble slider A10 on the second station 12 and the fourth station 14 along the X direction. The third disassembly / assembly mechanism 5 is mounted on the frame and is used to disassemble and assemble slider B20 on the first station 11 and the second station 12 along the Y direction. The fourth disassembly / assembly mechanism 6 is mounted on the frame and is used to disassemble and assemble slider B20 on the third station 13 and the fourth station 14 along the Y direction. The fifth disassembly / assembly mechanism 7 is mounted on the frame and is used to disassemble and assemble slider C30 on the first station 11, the second station 12, the third station 13, and the fourth station 14 along the Y direction.

[0048] like Figure 3As shown, the frame of this embodiment includes a second fixing plate 8 disposed below the first fixing plate 1. The second fixing plate 8 is disposed at a distance from the first fixing plate 1 and is used to support the first fixing plate 1.

[0049] like Figure 5 As shown, the first assembly / disassembly mechanism 3 of this embodiment includes a first support base 31, two first power elements 32, and two first bases 33. The first support base 31 is fixedly mounted on the first fixed plate 1. The two first power elements 32 are mounted on the first support base 31. Each first power element 32 has a first base 33 connected to its output shaft. One first base 33 corresponds to the first workstation 11, and the other first base 33 corresponds to the third workstation 13. Each first base 33 is provided with a first positioning post 34 for positioning the slider A10 at the corresponding workstation. The first power element 32 can be a pneumatic cylinder or an electric cylinder. When the output shaft of the first power element 32 extends, it can drive the slider A10 towards other sliders to assemble the transition block. When the output shaft of the first power element 32 retracts, it can drive the slider A10 away from other sliders to disassemble the transition block.

[0050] like Figure 3 , Figures 6 to 8 As shown, the second assembly / disassembly mechanism 4 in this embodiment includes a second support base 41, a second power element 42, a movable frame 43, and two second bases 44. The second support base 41 is installed below the second fixed plate 8 and is used to fix the main body of the second power element 42 (the second power element 42 is a cylinder or electric cylinder, and its main body is the cylinder body). The movable frame 43 is connected to the output shaft of the second power element 42 and can move up and down in the Z direction under the drive of the second power element 42, thereby driving the two second bases 44 installed on it to move in the X direction. One second base 44 corresponds to the second station 12, and the other second base 44 corresponds to the fourth station 14. Each second base 44 is provided with a second positioning post 45 for positioning the slider A 10 at the corresponding station.

[0051] Specifically, such as Figures 6 to 8As shown, the movable frame 43 includes a first base plate 431, two first side plates 432, two inner plates 433, and a connecting seat 434. The first base plate 431 is used to connect to the output shaft of the second power element 42. The two first side plates 432 are disposed opposite each other at both ends of the first base plate 431, and each of the two facing sides of the first side plates 432 is connected to an inner plate 433. The connecting seat 434 is disposed between the two inner plates 433, with its two ends connected to the two inner plates 433 respectively. Each inner plate 433 has a first elongated hole 4331 inclined to a horizontal plane, and each first side plate 432 has a second elongated hole 4321 inclined to a horizontal plane. The inclination directions of the first elongated hole 4331 on any inner plate 433 and the second elongated hole 4321 on the connected first side plate 432 are opposite. Two second bases 44 are slidably connected to the connecting base 434 in the X direction. The two second bases 44 are connected by a connecting shaft 435. The two ends of the connecting shaft 435 pass through the two second bases 44 respectively and extend into the first elongated hole 4331 and the second elongated hole 4321 on the corresponding side. The connecting shaft 435 can move within the first elongated hole 4331 and the second elongated hole 4321.

[0052] Taking the direction from the second station 12 to the first station 11, where the distance between the first elongated hole 4331 and the first base plate 431 gradually decreases and the distance between the second elongated hole 4321 and the first base plate 431 gradually increases as an example, when the transition block is in a closed state (i.e., when the transition block is to be disassembled), the output shaft of the second power element 42 extends, driving the movable frame 43 to move upward. The inner walls of the first elongated hole 4331 and the second elongated hole 4321 on each side contact the end of the connecting shaft 435 on the corresponding side and begin to apply force to the connecting shaft 435. As the movable frame 43 continues to move upward, the first side plate 432 and the corresponding side plate work together to push the second base 44 away from the other sliders on the station. When the transition block is to be assembled, the output shaft of the second power element 42 retracts, driving the movable frame 43 to move downward until the slider B 20 on the second base 44 contacts the first fixed plate 1. As the output shaft of the second power element 42 continues to retract, the slider B Unable to continue moving downwards, 20 slides toward other sliders on the workstation under the force applied to the inner walls of the first elongated hole 4331 and the second elongated hole 4321, thus closing the transition block.

[0053] With the second disassembly mechanism of the above structure, when the disassembly device of this embodiment is provided with two disassembly and assembly components, the two disassembly and assembly components can be arranged symmetrically. In this way, the first base plate 431 in the second disassembly and assembly component can be connected to the second power element 42 of the first disassembly and assembly component. Thus, the setting of the second power element 42 can be eliminated. At the same time, the above structure converts the Z-direction movement of the movable frame 43 into the X-direction movement of the second base 44, which helps to reduce the footprint of the device.

[0054] like Figure 9 As shown, the third assembly / disassembly mechanism 5 in this embodiment includes a third power element 51, a swing rod 52, a bracket 53, a first movable plate 54, and two third bases 55. The third power element 51 is mounted on the second fixed plate 8 via a third support base, the bracket 53 is mounted on the first fixed plate 1, and the first movable plate 54 is slidably connected to the first fixed plate 1. The swing rod 52 is hinged to the bracket 53. Specifically, the swing rod 52 passes through the bracket 53 and is hinged to the bracket 53. One end of the swing rod 52 is hinged to the output shaft of the third power element 51, and the other end is hinged to the first movable plate 54. The two third bases 55 are fixed to the first movable plate 54. One third base 55 corresponds to the first station 11, and the other third base 55 corresponds to the second station 12. Each third base 55 is provided with a third positioning post for positioning the slider B 20 at the corresponding station. The third power element 51 can be a cylinder or an electric cylinder. When its output shaft extends, it can drive the slider B 20 to move toward other sliders to realize the assembly of the transition block. When its output shaft retracts, it can drive the slider B 20 to move away from other sliders to realize the disassembly of the transition block.

[0055] The structure of the fourth splitting mechanism in this embodiment is generally similar to that of the third splitting mechanism, and will not be described in detail here.

[0056] like Figure 10 As shown, the fifth assembly / disassembly mechanism 7 in this embodiment includes a fifth power element 71, a cam groove plate 72, two fifth support seats 73, two fifth bases 74, and two sixth bases 75. The fifth power element 71 is fixed to the second fixing plate 8; the cam groove plate 72 is connected to the output shaft of the fifth power element 71 and is located below the first fixing plate 1, as shown... Figure 4 As shown, the cam groove has two sets of slots, each set including two slots 721 arranged in a figure-eight pattern. Specifically, the two sets of slots are distributed and identical along the X direction, and the two slots 721 within each set are not parallel, but rather form a preset angle with the X direction. Figure 9 As shown, one fifth support 73 is located between the first station 11 and the third station 13, and the other fifth support 73 is located between the second station 12 and the fourth station 14. Each fifth support 73 has a fifth base 74 and a sixth base 75 slidably connected to it. The fifth base 74 is located on the side of the sixth base 75 facing the first station 11 or the second station 12 for mounting the slider C30 corresponding to the third station 13 or the fourth station 14. Roller bearing followers 76 are respectively connected to the bottom of the fifth base 74 and the sixth base 75, and are movably connected to the slot 721 on the cam groove plate 72 through the roller bearing followers 76. The fifth base 74 has a fifth positioning post for positioning the slider C30, and the sixth base 75 has a sixth positioning post for positioning the slider C30.

[0057] Specifically, in this embodiment, the fifth support 73 between the first station 11 and the third station 13 has a fifth base 74 located closer to the first station 11 for mounting the slider C 30 corresponding to the first station 11, and a sixth base 75 located closer to the third station 13 for mounting the slider C 30 corresponding to the third station 13; the fifth support 73 between the second station 12 and the fourth station 14 has a fifth base 74 located closer to the second station 12 for mounting the slider C 30 corresponding to the second station 12, and a sixth base 75 located closer to the fourth station 14 for mounting the slider C 30 corresponding to the fourth station 14.

[0058] like Figures 11 to 14 As shown, in this embodiment, the fifth base 74 is connected to the fifth support base 73 via a first sliding bracket 77, and the sixth base 75 is connected to the fifth support base 73 via a second sliding bracket 78. Furthermore, the fifth support base 73 includes a second base plate 731 and two second side plates 732 disposed opposite to each other on both sides of the second base plate 731; the first sliding bracket 77 includes a first connecting portion 771, a first sliding portion 772 connected to the first connecting portion 771, and a first mounting portion 773 connected above the first sliding portion 772. A roller bearing follower 76 is connected below the first connecting portion 771. The first sliding portion 772 is used for sliding connection with the second base plate 731, and the first mounting portion 773 is used for mounting... The fifth base 74 is mounted; the second sliding bracket 78 includes a second connecting part 781, a second sliding part 782 connected to the second connecting part 781, and a second mounting part 783 connected above the second sliding part 782. A roller bearing follower 76 is connected below the second connecting part 781. The second sliding part 782 is used to slide with the second base plate 731, and the second mounting part 783 is used to mount the sixth base 75. The second sliding part 782 is offset from the first sliding part 772 to prevent them from interfering with each other during movement. The two second side plates 732 can guide the fifth base 74 and the sixth base 75 and limit them in the Z direction.

[0059] With the above structure, taking the example of the distance between two slots 721 in the same group of slots gradually increasing along the direction from the first station 11 to the second station 12, when the fifth power element 71 drives the cam slot plate 72 to move from the first station 11 to the second station 12, as the distance between the two slots 721 decreases, the fifth base 74 and the sixth base 75 on the same fifth support 73 move in opposite directions. That is, the fifth base 74 and the sixth base 75 respectively carry the slider C 30 on them and move in the direction away from the corresponding station. At this time, the transition block can be separated. When the fifth power element 71 drives the cam slot plate 72 to move from the second station 12 to the first station 11, the fifth base 74 and the sixth base 75 on the same fifth support 73 will move in opposite directions to approach the corresponding station, thereby realizing the assembly of the transition block.

[0060] like Figure 3 As shown, the frame in this embodiment also includes a support frame 91 disposed around the second fixed plate 8 and a third fixed plate 92 disposed on the upper end of the support frame 91. At least one pressing assembly is disposed on the third fixed plate 92, with one pressing assembly corresponding to one disassembly assembly, to press the sliders and embedded parts (metal terminals 120) during the assembly of the transition block. Further, each pressing assembly includes a sixth power element 93 fixed to the third fixed plate 92, a second movable plate 94 connected to the output shaft of the sixth power element 93, and multiple elastic pressing heads 95 connected to the second movable plate 94. Slider A 10, slider B 20, slider C 30, and embedded parts at each station are pressed by the corresponding elastic pressing head 95 to prevent slider lifting during the assembly of the transition block. Preferably, the elastic pressing head 95 used to press slider A 10, slider B 20, and slider C 30 is in a rolling connection with the corresponding slider to reduce the sliding resistance of each slider.

[0061] In summary, the working principle of the disassembly and assembly device in this embodiment is as follows: The metal terminal 120 is manually placed on the material rack 2, and the power components of multiple disassembly and assembly mechanisms simultaneously drive the corresponding sliders to move towards each other, and the sliders at each station close to form a transition block; the transition block with the embedded metal terminal 120 is placed into the injection mold to form a plastic body 110; the transition block and the product on it are taken out of the mold and placed on the station of the disassembly and assembly device, and the power components of multiple disassembly and assembly mechanisms simultaneously drive the corresponding sliders to move away from each other, so as to realize the simultaneous disassembly of the transition blocks at multiple stations; the product is removed, and then the metal terminal 120 is manually loaded, and the above steps are repeated.

[0062] Specific embodiments have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this invention. Therefore, the content of this specification should not be construed as a limitation of this invention.
