[0002] A folding door is used to separate spaces in a home. It is usually composed of multiple hinged folding door panels, with slide rails provided above or below the folding door. A sliding member that slides along the slide rail is provided at the upper end of each folding door panel, thereby forming a suspended folding door.

[0003] For example, Chinese patent application number (2022112035932) discloses a sliding part for hanging folding door screen partitions, which is supported by support rods, and the support rods can be offset to both sides of the side rods to ensure the structural strength of the support rods during actual use. It is not easy to be damaged. This offset effect also allows each door panel to be provided with the sliding part, reducing the carrying capacity of the sliding parts arranged at traditional intervals, and improving the service life, which indirectly makes the door panel smoother when unfolding or folding.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0021] Embodiment 1: This embodiment provides a sliding member for hanging a folding door, comprising: A support rod 1, one end of which is rotatably connected to a slider 2; The side rod 3 is obliquely installed on both sides of the support rod 1, and one end is fixedly connected to the support rod 1; A fixed cross bar 4 is installed at one end of the support bar 1 away from the slider 2; The support rod 1 is embedded with a metal rod 5, and the metal rod 5 and the sliding member are integrally injection molded; Meanwhile, the diameter of the metal rod 5 should be smaller than the diameter of the support rod 1 . Specifically, the diameter of the metal rod 5 can be 1 / 2 of the diameter of the support rod 1 .

[0022] It can be seen from the present embodiment that, during the injection molding of the support rod 1 of the sliding part, the metal rod 5 is embedded, and the metal rod 5, the support rod 1 and the sliding part are integrally injection molded. On the one hand, the embedded addition of the metal rod 5 can effectively improve the structural strength of the support rod 1 and extend the service life. On the other hand, the integral injection molding of the metal rod 5, the support rod 1 and the sliding part can effectively improve the embedded connection strength of the metal rod 5, improve the structural stability and further extend the service life.

[0023] Embodiment 2: This embodiment provides an injection molding device for a sliding member of a hoisting folding door, comprising: A frame 6, in which a fixed die plate 9 and a movable die plate 10 corresponding to the fixed die plate 9 are installed, a fixed die 11 is installed on the fixed die plate 9, a movable die 12 is installed on the movable die plate 10, and a cavity 13 adapted to the sliding member is opened on the opposite sides of the fixed die 11 and the movable die 12; A feeding mechanism 7 is installed on the side of the frame 6 and is used to feed the metal rod 5; The pushing mechanism 8 is installed between the frame 6 and the feeding mechanism 7 and is used to grab the metal rod 5 and push it into the cavity 13; Among them, the fixed mold 11 and the movable mold 12 are formed with a first insertion hole 14 and a guide hole 15 for pushing the metal rod 5 after the mold is closed, and the first insertion hole 14 is connected with the cavity 13, and the first insertion hole 14 and the guide hole 15 are coaxially opened on both sides of the cavity 13; At the same time, the movable mold 12 and the fixed mold 11 are also provided with injection channels, and the injection channels are connected to an injection system, a temperature control system for heating and cooling, and a feeding system for providing materials to the injection system, and the injection system, the temperature control system, and the feeding system are conventional settings of the injection molding machine, which are existing mature technologies and will not be described in detail here; Furthermore, the smaller the axial dimension of the guide hole 15 is, the better, and specifically, 2-3 mm may be adopted.

[0024] It can be seen from this embodiment that by arranging a push mechanism 8 and a feeding mechanism 7 on the side of the injection mold, the metal rod 5 is fed by the feeding mechanism 7, and then the push mechanism 8 grabs and pushes it into the cavity 13, so that the metal rod 5 can be automatically fed; In addition, the opening of the guide hole 15 can provide support for the metal rod 5, and during injection molding, it can avoid the influence of material flow that causes the metal rod 5 to tilt in the axial direction. In addition, the axial dimension of the guide hole 15 is set to be smaller, which can prevent excessive metal rod 5 from protruding from the support rod 1 after injection molding, effectively controlling costs and ensuring product quality, avoiding subsequent cutting, and improving production efficiency.

[0025] Embodiment 3: This embodiment provides an injection molding device for a sliding member of a hoisted folding door. In addition to the technical solutions of the above embodiments, it also has the following technical features. The pushing mechanism 8 includes: The base 80 is installed on the side of the frame 6, and is equipped with a rotating assembly 81 for driving the base 80 to rotate and a moving assembly 82 for driving the base 80 to move horizontally; A top column 83 is mounted on the side of the base 80 and is axially slidably mounted with a top rod 84; The top block 85 is slidably connected to the side of the top column 83 away from the base 80, and a spring 86 is arranged between the top column 83, and a second plug hole 87 adapted to the metal rod 5 is axially opened; The reverse thrust structure 88 is installed at one end of the top column 83 close to the top block 85, and is used to connect the top block 85 and the top rod 84, and is used to push the top rod 84 in the axial direction opposite to the moving direction of the top block 85; Among them, the moving component 82 can adopt the slider 2 slide rail and the screw transmission device, and the rotating component 81 can adopt the indexer. Therefore, the specific structures of the moving component 82 and the rotating component 81 are existing mature technologies and will not be repeated here.

[0026] It can be seen from the present embodiment that by adopting the reverse thrust structure 88, the metal rod 5 can be pushed into place, the protruding part of the metal rod 5 on the sliding part can be effectively controlled, the product cost can be reduced, and the product quality can be ensured. The setting of the ejector block 85 and the spring 86, on the one hand, can make the ejector column 83 adopt soft contact when contacting the fixed mold 11 and the movable mold 12, and on the other hand, the axial deformation can be used as the input of the reverse thrust structure 88, effectively ensuring that the ejector rod 84 is ejected in the axial direction, and pushing the metal rod 5 through the first plug hole 14 and then entering the cavity 13, thereby improving the stability of the metal rod 5 feeding.

[0027] Embodiment 4: This embodiment provides an injection molding device for a sliding member of a hoisted folding door. In addition to the technical solutions of the above embodiments, it also has the following technical features. The reverse thrust structure 88 includes: The rack 880 is installed on the side of the top column 83, and one end of the rack extends to the side of the top block 85 and is connected to the top block 85 through a connecting ear 881; The first rotating shaft 882 penetrates the top column 83 in the radial direction and is rotatably connected to the top column 83; The gear 883 is sleeved on the first rotating shaft 882 and is located outside the top column 83 and meshes with the rack 880; The cam 884 is sleeved on the first rotating shaft 882 and is located inside the top column 83; The stop bar 885 is mounted on the push rod 84 and is pushed by the cam 884 to move axially, and drives the push rod 84 to move axially; The blocking bar 885 and the top rod 84 and the connecting ear 881 and the top block 85 can be welded, the rack 880 and the connecting ear 881 can be fixed with bolts, and the first rotating shaft 882 and the top column 83 can be connected with a bearing.

[0028] It can be seen from this embodiment that when the moving assembly 82 pushes the ejector pin 83 to move toward one side of the mold, the ejector block 85 will continue to move after contacting the fixed mold 11 and the movable mold 12, which will cause the ejector pin 83 and the ejector block 85 to approach each other, thereby driving the rack 880 to move, and driving the gear 883 and the first rotating shaft 882 to rotate, and then driving the cam 884 to push the stop bar 885, thereby causing the ejector pin 84 to be pushed out and push the metal rod 5 through the first insertion hole 14 and completely enter the cavity 13; In order to improve the driving stability, there are two racks 880, which are respectively located at the two ends of the first rotating shaft 882, and there are two first rotating shafts 882, and gears 883 are provided at both ends. At the same time, there are two cams 884 and two baffles 885, and they are symmetrically arranged to improve the stability of pushing the push rod 84.

[0029] Embodiment 5: This embodiment provides an injection molding device for a sliding member of a hoisted folding door, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The top rod 84 is an elastic telescopic rod, and one end of the rod is slidably connected to the second plug hole 87, and the other end of the rod is slidably connected to the top column 83; The static friction force between the metal rod 5 and the inner wall of the second insertion hole 87 and the elastic force of the push rod 84 after axial compression are balanced.

[0030] It can be seen from this embodiment that by inserting the metal rod 5 into the second insertion hole 87, the axis of the metal rod 5 and the second insertion hole 87 are ensured to coincide, the metal rod 5 is ensured to be inserted into the first insertion hole 14, and the static friction between the metal rod 5 and the inner wall of the second insertion hole 87 and the elastic force of the ejector rod 84 after compression are balanced to ensure that the metal rod 5 does not have excessive deviation in the axial direction, thereby improving the feeding accuracy; At the same time, the push rod 84 is a telescopic rod that can also provide compensation in the axial direction. Through the elastic restoring force, it is ensured that after the metal rod 5 is inserted into the cavity 13 through the pushing mechanism 8, that is, the metal rod 5 leaves the second plug hole 87 and loses the static friction between the metal rod 5 and the inner wall of the second plug hole 87, the length of the push rod 84 extending out of the push block 85 can be increased through elastic recovery, thereby ensuring that the metal rod 5 is pushed into place in the cavity 13. The elastic force also has a stabilizing effect on the axial direction of the metal rod 5, thereby improving the stability of the metal rod 5 during injection molding.

[0031] Embodiment 6: This embodiment provides an injection molding device for a sliding member of a hoisted folding door. In addition to the technical solutions of the above embodiments, it also has the following technical features. The feeding mechanism 7 includes: A silo 70 is mounted on a base 80 and is used to place the metal rod 5; A lifting assembly 71 is installed in the silo 70 and is used for lifting a single metal rod 5; The material lifting assembly 72 is installed above the silo 70 and is used to grab the metal rod 5 on the material lifting assembly 71; The bottom surface of the silo 70 is tilted toward the side of the material ejection assembly 71, so as to facilitate guiding the metal rod 5 in the silo 70 to the material ejection assembly 71; At the same time, the lifting component 71 is also provided with an infrared detection device for detecting whether the metal rod 5 is lifted by the lifting component 71. When the lifting component 71 fails to lift a single metal rod 5, the lifting of the metal rod 5 is repeated until it is detected that a single metal rod 5 is lifted; and if the metal rod 5 is not detected to be lifted after several lifts, an alarm is issued, and the silo 70 needs to be replenished with the metal rod 5. The infrared detection device is already mature and will not be described here.

[0032] It can be seen from this embodiment that the continuous feeding of the metal rod 5 is ensured by the setting of the silo 70, the pushing assembly 71 facilitates the single feeding of the metal rod 5 to ensure the feeding accuracy, and the lifting assembly 72 facilitates the movement of the metal rod 5 to a suitable position to facilitate the grabbing of the pushing mechanism 8; At the same time, the metal rod 5 on the lifting assembly 71 is detected by an infrared detection device, which is convenient for controlling and driving the lifting assembly 71 to continue lifting until the single metal rod 5 is lifted, thereby ensuring the metal rod 5 on the lifting assembly 72 and the timeliness of the pushing mechanism 8 to grab the metal rod 5, thereby ensuring production efficiency.

[0033] Embodiment 7: This embodiment provides an injection molding device for a sliding member of a hoisted folding door. In addition to the technical solutions of the above embodiments, it also has the following technical features. The lifting component 71 includes: The top plate 710 is slidably connected in the silo 70, and a slot hole 711 adapted to the top plate 710 is opened on the bottom surface of the silo 70, and an arc groove 712 adapted to the metal rod 5 is opened on the top surface of the top plate 710; The turntable 713 is mounted on the base 80 and connected to the top plate 710 by a connecting rod 714, and the connecting rod 714 is located on a side of the turntable 713 away from the axis; The first motor 715 is mounted on the base 80 and is used to drive the turntable 713 to rotate; The two ends of the connecting rod 714 are respectively connected to the top plate 710 and the rotating disk 713 by bearings.

[0034] It can be seen from the present embodiment that the turntable 713 is driven to rotate by the first motor 715, and then the top plate 710 is driven to rise and fall through the connecting rod 714, and after a single metal rod 5 fails to be lifted, it can be lifted multiple times, effectively ensuring a single lifting of the metal rod 5, facilitating the grabbing of the lifting assembly 72.

[0035] Embodiment 8: This embodiment provides an injection molding device for a sliding member of a hoisted folding door. In addition to the technical solutions of the above embodiments, it also has the following technical features. The material lifting component 72 includes: The second rotating shaft 720 has bearings at both ends connected to brackets 721 and a second motor 722 at one end; A plurality of electromagnetic adsorption members 723 are provided and are arranged around the second rotating shaft 720 at equal intervals, and a partition plate 724 is provided between two adjacent electromagnetic adsorption members 723; The baffle 725 is sleeved on one side of the second rotating shaft 720 close to the second motor 722 and is used to keep the axial position of the metal rod 5 consistent when the pushing mechanism 8 grabs the metal rod 5; The baffle 725 can be connected to the base 80 and has a circular hole through which the second rotating shaft 720 passes; At the same time, in order to ensure that the electromagnetic adsorption member 723 adsorbs the metal rod 5, the metal rod 5 can be made of a material that can be adsorbed by a magnet, such as iron or iron alloy.

[0036] It can be seen from this embodiment that the electromagnet 7231 is used to adsorb and release the metal rod 5 by turning on and off the power, which facilitates the loading of the metal rod 5 and the grasping of the pushing mechanism 8, thereby improving the convenience and efficiency of loading the metal rod 5. At the same time, the rotation of the second rotating shaft 720 can realize the orderly and continuous loading of multiple metal rods 5, thereby ensuring the timeliness of loading. In addition, the setting of the baffle 725 makes it easier for the pushing mechanism 8 to grab the metal rod 5, that is, after the metal rod 5 is inserted into the second socket 87, it is affected by the elastic force of the push rod 84 and the static friction force, thereby pushing the metal rod 5 to abut against the baffle 725, effectively ensuring that one end of the metal rod 5 inserted into the second socket 87 and the other end of the metal rod 5 can maintain a consistent axial position.

[0037] Embodiment 9: This embodiment provides an injection molding device for a sliding member of a hoisted folding door. In addition to the technical solutions of the above embodiments, it also has the following technical features. The electromagnetic adsorption member 723 includes: The housing 7230 is mounted on the surface of the second rotating shaft 720 and is located between two adjacent partitions 724; The electromagnet 7231 is installed in the housing 7230 and is arranged in plurality along the axial direction of the second rotating shaft 720 , and is connected with a positive electrode connection line 7232 and a negative electrode connection line 7233 and extends out of the housing 7230 ; The electric contact pieces 7234 are provided with two sleeves on the surface of the second rotating shaft 720 and are in a semicircular shape, and electric contacts 7235 are provided at one end of the positive electrode connection line 7232 and the negative electrode connection line 7233 to electrically contact and connect the two electric contact pieces 7234 respectively; A power source, electrically connected to the electrical contact 7234; The electric contact sheet 7234 is fixedly arranged and does not rotate with the second rotating shaft 720. The electric contact sheet 7234 is arranged along the rotating direction of the second rotating shaft 720, starting from the lowest position of the second rotating shaft 720, so that the electromagnet 7231 at the lowest position of the second rotating shaft 720 is energized, and the electromagnet 7231 at the highest position of the second rotating shaft 720 is de-energized. At the same time, the housing 7230 may be made of magnetic shielding material, and the partition 724 may be made of insulating material, thereby reducing the mutual influence between two adjacent electromagnetic adsorption members 723; Furthermore, the electric contact pieces 7234 are arranged side by side and can be fixed on the inner wall of the circular hole of the baffle 725, and are connected to the positive and negative electrode ends of the power source through two wires, while the positive electrode connection wire 7232 and the negative electrode connection piece can be bonded to the surface of the second conversion shaft; The housing 7230 is also provided with a groove adapted to the metal rod 5, thereby ensuring the position accuracy of the metal rod 5 after the metal rod 5 is adsorbed, and ensuring that the pusher assembly grabs the metal rod 5.

[0038] It can be seen from this embodiment that the on and off of the electromagnet 7231 can be effectively controlled by the semicircular electric contact piece 7234 and the electric contact 7235 connected to the positive connecting wire 7232 and the negative connecting wire 7233 on the electromagnet 7231, thereby improving the stability and convenience of feeding. Specifically, assuming that a certain electromagnetic adsorption member 723 rotates with the second rotating shaft 720 and rotates to the lowest position of the second rotating shaft 720, the electric contact 7235 contacts the electric contact sheet 7234, the electromagnet 7231 is energized, and the metal rod 5 is adsorbed. As the second rotating shaft 720 rotates and before rotating to the highest position of the second rotating shaft 720, the electric contact 7235 is always in contact with the electric contact sheet 7234, and the electromagnet 7231 is always energized to maintain the adsorption of the metal rod 5. However, when it moves to the highest position of the second rotating shaft 720, the electric contact 7235 is not in contact with the electric contact sheet 7234, the electromagnet 7231 is de-energized, and the metal rod 5 is released. At this time, the electromagnetic adsorption member 723 supports the metal rod 5, and the pushing mechanism 8 grabs the metal rod 5, effectively controlling the feeding of the metal rod 5. Furthermore, when the electromagnetic adsorption part 723 rotates from the highest position side to the lowest position side of the second rotating shaft 720, the electromagnet 7231 is in a power-off state. Even if the pushing mechanism 8 has not completed the grabbing of the metal rod 5, the metal rod 5 can be prompted to automatically fall back into the hopper 70. Therefore, an infrared detection device should also be provided on the pushing mechanism 8 to detect that when the pushing mechanism 8 has not completed the grabbing of the metal rod 5, the second rotating shaft 720 continues to rotate, and the pushing mechanism 8 grabs the metal rod 5 again, thereby effectively ensuring the loading of the metal rod 5 and ensuring product quality.

[0039] Embodiment 10: This embodiment provides an injection molding process of an injection molding device for a sliding member of a suspended folding door, comprising the following steps: S1: The first motor 715 drives the turntable 713 to rotate, and drives the top plate 710 to rise and fall through the connecting rod 714, and lifts a metal rod 5 from the silo 70 each time it is lifted; S2: The second rotating shaft 720 drives the plurality of electromagnetic adsorption members 723 to rotate, and the electromagnet 7231 located at the lowest position of the second rotating shaft 720 is energized and adsorbs the metal rod 5 on the top plate 710; S3: The second rotating shaft 720 rotates and moves the metal rod 5 to the highest position of the second rotating shaft 720, and at this time, the electromagnet 7231 is powered off, and the metal rod 5 is supported by the base 80; S4: The moving assembly 82 drives the top column 83 to approach the metal rod 5, and under the setting of the baffle 725, the metal rod 5 is inserted into the second insertion hole 87 of the top block 85 until the static friction between the metal rod 5 and the inner wall of the second insertion hole 87 and the elastic force of the top rod 84 after compression are balanced; S5: The moving assembly 82 drives the top column 83 to move, and the rotating assembly 81 drives the top column 83 to rotate 180°; S6: The movable mold 12 is molded with the fixed mold 11, and the moving assembly 82 drives the ejector 83 to push the metal rod 5 into the first insertion hole 14, and after the ejector block 85 contacts the fixed mold 11 and the movable mold 12, the spring 86 is compressed to drive the reverse thrust assembly to cause the ejector 84 to push the metal rod 5 to be inserted, until the metal rod 5 passes through the second insertion hole 87 and completely enters the cavity 13; S7: inject material into the cavity 13, and after the mold is shaped and cooled, the movable mold 12 is opened, and then the moving assembly 82 drives the ejector 83 to reset; S8: Repeat the above steps S1 to S8.

[0040] It can be seen from this embodiment that by first loading the metal rod 5 and then injection molding the sliding part, the connection strength and stability between the metal rod 5 and the sliding part are effectively guaranteed, the structural stability of the sliding part during use is guaranteed, and the service life is further extended; Furthermore, because the ejector rod 84 is an elastic telescopic rod, after the movable mold 12 is removed and the sliding part is demoulded, the sliding part can be ejected, thereby improving the demoulding effect and the material discharge efficiency.
