Description

Technical Field

[0001] The invention relates to the field of buckle molding, and in particular to a plastic buckle molding device and a molding method for an optical fiber fixing buckle. Background Art

[0002] The plastic clip molding device is a mechanical equipment specially used for producing plastic clips. This device transforms plastic raw materials into clip products with specific shapes, sizes and functions through a specific process flow.

[0003] The existing plastic buckle molding device needs to use a conveying mechanism to assist in transporting the plastic parts downward after the plastic parts are demolded, to ensure that the plastic parts can be taken out of the mold and transported to a storage box for storage. After the plastic parts are successfully demolded, the plastic parts are transported downward to the storage box through the conveying mechanism, and the parts on the conveying mechanism for receiving the plastic parts need to be reset to facilitate receiving the next plastic part.

[0004] The prior art also has the following defects: some injection molding machines have a short mold opening and closing cycle each time, and produce plastic parts at a fast speed, but the components on the conveying mechanism used to receive plastic parts (such as trays, conveyor belts, etc.) need a certain amount of time to rise to the initial position after descending to receive the plastic parts in order to prepare to receive the next plastic part. If the components on the conveying mechanism that receive the plastic parts have not been reset after the next plastic part is produced, the plastic parts will wait in the mold for the conveying mechanism to reset, thereby reducing the overall production efficiency. In most cases, each plastic part falls into a storage box from a fixed channel. When they fall into the storage box, they may collide, squeeze or stack with each other, resulting in uneven distribution.

[0005] Therefore, the present application provides a plastic clip molding device and a molding method for an optical fiber fixing clip to meet the needs. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example: Reference Figure 1-Figure 10A plastic buckle molding device shown in the figure includes an injection molding machine body 1, a base of the injection molding machine body 1 is provided with a through hole 104 connected to the outside, a switch door 101 is hinged at the through hole 104, a movable mold, a fixed mold, an injection molding mechanism, a mold closing cylinder, and a mold opening cylinder are arranged on the injection molding machine body 1, an ejector is installed on the movable mold, a protective door 102 is installed on the injection molding machine body 1, and a control panel (not shown in the figure) is installed on the injection molding machine body 1.

[0039] The mold closing cylinder can move the movable mold toward the fixed mold through the connecting rod mechanism to complete the mold closing action and ensure that the mold can be tightly closed during high-pressure injection. The molten plastic is injected into the mold cavity through the injection mechanism of the injection molding machine. After the injection is completed, a certain injection pressure is maintained to prevent the plastic from shrinking and wait for the plastic to cool and solidify in the mold cavity. Then the mold opening cylinder provides driving force to separate the movable mold from the fixed mold. Driven by the pneumatic system, the ejector moves quickly, contacts the plastic part and applies force to allow the plastic part to be smoothly ejected from the mold.

[0040] A through blanking port 103 is provided on the base of the injection molding machine body 1, and a material receiving piece 2 is fixedly installed at the blanking port 103. A feeding port is provided at the upper end of the material receiving piece 2, and a discharge port is provided at the lower end of the material receiving piece 2. The discharge port of the material receiving piece 2 is connected with the feeding port of the material receiving piece 2, and the diameter of the discharge port of the material receiving piece 2 is smaller than the diameter of the feeding port of the material receiving piece 2. The diameter of the material receiving piece 2 is gradually expanded from bottom to top. This design can well guide the plastic parts to smoothly enter the material receiving piece 2 from the blanking port 103 of the injection molding machine, and ensure that the plastic parts fall into the movable tube 4 more smoothly.

[0041] A movable tube 4 is rotatably connected to the discharge port of the material receiving piece 2, and the material receiving piece 2 is communicated with the movable tube 4. The movable tube 4 consists of an upper vertical tube 41, a curved tube 42, and a lower vertical tube 43, and the upper vertical tube 41, the curved tube 42, and the lower vertical tube 43 are sequentially communicated. The connection between the upper vertical tube 41 and the curved tube 42, and between the curved tube 42 and the lower vertical tube 43 are all arc-shaped, making the connection smoother and allowing the plastic parts to pass smoothly. The curved tube 42 allows the plastic parts to smoothly transition when changing direction, reducing the resistance and impact caused by sudden changes in direction. The upper vertical tube 41 of the movable tube 4 is communicated with the material receiving piece 2.

[0042] A power assembly 3 is provided on the outer side of the movable tube 4. The power assembly 3 can allow the movable tube 4 to rotate around the axis of the upper vertical tube 41. The power assembly 3 includes a power motor 31, a driving pulley 32, a belt 33, and a driven pulley 34. The power motor 31 is electrically connected to the control panel, and the top of the power motor 31 is fixedly connected to the inner wall of the base of the injection molding machine body 1. The driving pulley 32 is fixedly connected to the output end of the power motor 31, and the driven pulley 34 is fixedly sleeved on the upper vertical tube 41. The belt 33 is cooperatively connected between the driven pulley 34 and the belt 33.

[0043] The power motor 31 is started through the control panel, and the output end of the power motor 31 drives the driving pulley 32 to rotate, and the driving pulley 32 drives the driven pulley 34 to rotate through the belt 33, and the driven pulley 34 drives the upper vertical tube 41 to rotate, so that the movable tube 4 rotates in the axial direction of the upper vertical tube 41.

[0044] A plurality of conveying pipes 7 are fixedly arranged inside the base of the injection molding machine body 1 and below the movable pipe 4. The conveying pipes 7 are hollow cylinders, that is, the interior of the conveying pipes 7 is hollow, and the upper and lower ends of the conveying pipes 7 are provided with openings. The plurality of conveying pipes 7 are arranged in a circular array, and the center lines between the plurality of conveying pipes 7 coincide with the axis of the upper vertical pipe 41. The upper vertical pipe 41 is connected to one of the conveying pipes 7 to convey the plastic parts to the interior of this conveying pipe 7. The movable pipe 4 can be connected to the next conveying pipe 7 after rotating by the power assembly 3, and the next plastic part can be transferred to the interior of the next conveying pipe 7. In this way, the movable pipe 4 can convey the plastic parts to be produced to the interior of the remaining conveying pipes 7 in order (the circular arrangement order of the plurality of conveying pipes 7).

[0045] It should be noted that: after the production of the plastic part is completed, it enters one of the conveying tubes 7 under the guidance of the receiving piece 2 and the movable tube 4. The movable tube 4 needs to be quickly switched to the next conveying tube 7 to wait for the next plastic part to be produced. While the movable tube 4 is switching, the last produced plastic part completes the conveying work alone in the corresponding conveying tube 7, so that the movable tube 4 can receive the next plastic part without waiting for the previous plastic part to complete the conveying work.

[0046] A stabilizing component 8 is provided on the outer side of the conveying pipe 7. The stabilizing component 8 can ensure the stable docking of the movable pipe 4 and the conveying pipe 7. The stabilizing component 8 includes two electric push rods 81, two fixed gaskets 82, and a closed limit ring 83. The two fixed gaskets 82 are symmetrically fixedly connected to the outer wall of the conveying pipe 7 respectively, and the electric push rod 81 is fixedly connected to the top of the corresponding fixed gasket 82. The electric push rod 81 is electrically connected to the control panel. The output ends of the two symmetrically arranged electric push rods 81 are commonly fixedly connected to the bottom of the closed limit ring 83. The closed limit ring 83 is slidably sleeved on the outer side of the conveying pipe 7, and the inner circle diameter of the closed limit ring 83, the outer circle diameter of the conveying pipe 7, and the outer circle diameter of the lower vertical pipe 43 are all the same.

[0047] When the movable tube 4 is completely docked with one of the conveying tubes 7, the electric push rod 81 is started through the control panel, and the output end of the electric push rod 81 drives the closed limit ring 83 to move upward a specified distance, so that the closed limit ring 83 rises to the docking point between the lower vertical tube 43 and the conveying tube 7, so that the movable tube 4 and the conveying tube 7 are restricted inside the closed limit ring 83 as a whole to prevent the two from offsetting, so that the plastic parts can be smoothly transferred from the movable tube 4 to the conveying tube 7.

[0048] The inside of the conveying pipe 7 is provided with a receiving assembly for receiving plastic parts, and the receiving assembly includes a receiving plate 9 and a receiving ring 10. The receiving ring 10 is a hollow cylinder, and the top of the receiving ring 10 is processed into an arc shape. The receiving plate 9 is horizontally slidably arranged at the bottom of the receiving ring 10, and the receiving plate 9 and the receiving ring 10 are vertically slidably arranged inside the conveying pipe 7 as a whole. The receiving plate 9 and the receiving ring 10 are initially located inside the conveying pipe 7 and close to the top. When the plastic parts fall into the conveying pipe 7, they are received by the receiving assembly, that is, the plastic parts are inside the receiving ring 10, and the plastic parts are on the top of the receiving plate 9. Then the receiving assembly can move vertically downward to transport the plastic parts downward.

[0049] During the injection molding process, plastic parts are usually newly formed and in a relatively fragile state. Direct impact with right angles or sharp edges may cause scratches, deformation or even breakage on the surface of the plastic parts. The arc-shaped design at the top of the receiving ring 10 can effectively prevent damage to the plastic parts caused by right angles or sharp edges, and the arc-shaped top can provide a natural guiding surface, allowing the plastic parts to enter the receiving ring 10 more smoothly.

[0050] The upper end of the receiving plate 9 is provided with a sponge (not shown in the figure). As a soft material, the sponge has good buffering performance, which can reduce direct damage to the plastic parts, thereby protecting the integrity and surface quality of the plastic parts.

[0051] A fixed plate 12 is fixedly arranged at the inner bottom of the base of the injection molding machine body 1, and a plurality of discharge ports 121 are opened on the fixed plate 12. The discharge ports 121 are arranged one by one with the conveying pipes 7, and the discharge ports 121 are located directly below the corresponding conveying pipes 7. An arc-shaped limiting ring 122 is fixedly connected to the bottom of the fixed plate 12. A storage member 13 is slidably arranged on the inner side of the arc-shaped limiting ring 122. The storage member 13 is used to store plastic parts. The bottom of the storage member 13 is in sliding contact with the inner bottom of the base of the injection molding machine body 1. A storage groove 131 is opened at the position corresponding to each discharge port 121 of the storage member 13. The storage groove 131 is used to hold plastic parts. The shape of the storage groove 131 is adapted to the shape of the plastic parts. A handle 132 is fixedly connected to the front side of the storage member 13. By setting the handle 132, the storage member 13 can be conveniently slid to the inner side of the arc-shaped limiting ring 122, and the storage member 13 can be conveniently drawn out from the inner side of the arc-shaped limiting ring 122.

[0052] The plastic parts can be released inside the conveying pipe 7, and then enter the corresponding storage groove 131 through the outlet of the conveying pipe 7 and the corresponding discharge port 121 in turn to realize the storage of the plastic parts. Then the next plastic part is released inside the next conveying pipe 7, and enters the corresponding storage groove 131. In this way, the plastic parts to be produced enter the remaining storage grooves 131 in order to realize neat storage. After all the storage grooves 131 on the storage part 13 are used, the staff will pull out the storage part 13 and replace it with a new storage part 13. The work of replacing the storage part 13 needs to be completed before the arrival of the next plastic part.

[0053] Two connecting rods 51 are fixedly connected to the inner wall of the base of the injection molding machine body 1 . A fixing ring 5 is fixedly connected to the bottoms of the two connecting rods 51 . The movable tube 4 rotates inside the fixing ring 5 .

[0054] A lifting assembly 6 is provided on the outside of each conveying pipe 7. The lifting assembly 6 is used to realize the vertical movement of the material receiving assembly. The multiple lifting assemblies 6 work without interfering with each other. The lifting assembly 6 includes a lifting motor 61 fixedly connected to the bottom of the fixing ring 5. The lifting motor 61 is electrically connected to the control panel. The output end of the lifting motor 61 is fixedly connected to a threaded rod 62. The bottom end of the threaded rod 62 is rotatably connected to the fixed disk 12. The outer side of the threaded rod 62 is threadedly connected to a moving block 63. The end of the moving block 63 away from the threaded rod 62 is fixedly connected to the material receiving ring 10 of the material receiving assembly. A vertical strip notch 71 is provided on the outer side of the conveying pipe 7. The vertical strip notch 71 is used for the passage of the moving block 63. A guide rod 64 is fixedly provided on the outer side of the threaded rod 62. The upper and lower ends of the guide rod 64 are respectively fixedly connected to the fixing ring 5 and the fixing disk 12. The guide rod 64 passes through the moving block 63. The guide rod 64 is used to realize the vertical movement of the moving block 63 to prevent the moving block 63 from deviating from the direction when moving.

[0055] The lifting motor 61 is started through the control panel, and the output end of the lifting motor 61 drives the threaded rod 62 to rotate, so that the moving block 63 moves vertically under the guidance of the guide rod 64, and the moving block 63 drives the corresponding material receiving assembly to move vertically.

[0056] A release assembly 11 is provided at the bottom of the moving block 63. The release assembly 11 can release the plastic parts inside the conveying pipe 7 so that they can pass through the corresponding discharge port 121 smoothly. The release assembly 11 includes an electric telescopic rod 111, a connecting plate 112, and a driving rod 113. The electric telescopic rod 111 is fixedly connected to the bottom of the corresponding moving block 63. The output end of the electric telescopic rod 111 is fixedly connected to the connecting plate 112. The connecting plate 112 is fixedly connected to the driving rod 113 on the side away from the electric telescopic rod 111. The driving rod 113 is staggered with the output end of the electric telescopic rod 111. The end of the driving rod 113 away from the connecting plate 112 passes through the vertical strip notch 71 and is fixedly connected to the corresponding receiving plate 9. A transverse arc notch 72 is provided on the outside of the conveying pipe 7 near the bottom. The transverse arc notch 72 is connected to the vertical strip notch 71, and the transverse arc notch 72 is adapted to the receiving plate 9.

[0057] When the receiving plate 9 moves vertically downward to the position of the transverse arc notch 72, the operation of the lifting assembly 6 is stopped, and the control panel starts the electric telescopic rod 111. The output end of the electric telescopic rod 111 drives the connecting plate 112, the driving rod 113, and the receiving plate 9 to move horizontally as a whole, so that the receiving plate 9 moves horizontally through the transverse arc notch 72, so that the receiving plate 9 and the receiving ring 10 are gradually separated, so that the bottom opening of the receiving ring 10 is exposed, and the plastic parts will not be taken away by the receiving plate 9 under the restriction of the inner wall of the receiving ring 10. Then the plastic parts fall from the bottom opening of the receiving ring 10, and enter the corresponding storage tank 131 through the bottom opening of the conveying pipe 7 and the discharge port 121 in turn.

[0058] A clamping block 91 is fixedly connected to the top and edge of the receiving plate 9, and a clamping groove is provided at the bottom of the receiving ring 10 corresponding to the position of the clamping block 91, and the clamping groove is adapted to the clamping block 91. When the receiving plate 9 needs to be reset, the driving rod 113 pushes the receiving plate 9 toward the inside of the conveying pipe 7, and the clamping block 91 docks with the clamping groove to limit the travel of the receiving plate 9 and prevent the receiving plate 9 from excessive movement under the push of the driving rod 113.

[0059] A molding method for an optical fiber fixing buckle comprises the following steps:

[0060] S1: The mold closing cylinder can move the movable mold toward the fixed mold to complete the mold closing action;

[0061] S2: The molten plastic is injected into the mold cavity through the injection molding mechanism of the injection molding machine, and the plastic is cooled and solidified in the mold cavity;

[0062] S3: The mold opening cylinder can separate the movable mold from the fixed mold, and the plastic part can be smoothly removed from the mold under the action of the ejector.

[0063] Working principle:

[0064] After the plastic part is demoulded, it falls into the movable tube 4 through the receiving piece 2. Before the first plastic part is produced, the movable tube 4 maintains a docking state with one of the conveying tubes 7, and then falls into the first conveying tube 7 through the movable tube 4. Then, the power motor 31 is started through the control panel. The output end of the power motor 31 drives the active pulley 32 to rotate. The active pulley 32 drives the driven pulley 34 to rotate through the belt 33. The driven pulley 34 drives the upper vertical tube 41 to rotate, so that the movable tube 4 rotates along the axial direction of the vertical tube 41, and then the movable tube 4 is quickly switched to the second conveying tube 7. Then, the corresponding electric push rod 81 is started through the control panel. The output end of the electric push rod 81 drives the closed limit ring 83 to move upward by a specified distance, so that the closed limit ring 83 rises to the docking point between the lower vertical tube 43 and the second conveying tube 7, so that the movable tube 4 and the first conveying tube 7 are restricted inside the closed limit ring 83 as a whole, and start waiting for the second plastic part.

[0065] After the movable tube 4 and the conveying tube 7 are docked, they are in a state of abutting each other in the vertical direction. When the movable tube 4 needs to be moved to the next conveying tube 7 after unloading, the electric push rod 81 is started to drive the closed limit ring 83 to descend, so that the closed limit ring 83 is separated from the docking position of the movable tube 4 and the conveying tube 7, and the movable tube 4 rotates to the position of the next conveying tube 7 and abuts against the next conveying tube 7;

[0066] While the movable tube 4 is switched, the lifting motor 61 on the first conveying tube 7 is started through the control panel, and the output end of the lifting motor 61 drives the threaded rod 62 to rotate, so that the moving block 63 moves vertically downward under the guidance of the guide rod 64, and the moving block 63 drives the corresponding material receiving assembly to move vertically downward. When the material receiving plate 9 moves vertically downward to the position of the horizontal arc-shaped notch 72, the operation of the lifting assembly 6 is stopped, and the control panel starts the electric telescopic rod 111. The output end of the electric telescopic rod 111 drives the connecting plate 112, the driving rod 113, and the material receiving plate 9 to move horizontally as a whole, so that the material receiving plate 9 passes through the horizontal arc-shaped notch 72. Horizontal movement occurs, so that the receiving plate 9 and the receiving ring 10 are gradually separated, so that the bottom opening of the receiving ring 10 is exposed, and the first plastic part will not be taken away by the receiving plate 9 under the restriction of the inner wall of the receiving ring 10. Then the first plastic part falls from the bottom opening of the receiving ring 10, and passes through the bottom opening of the first conveying pipe 7 and the discharge port 121 in turn into the corresponding storage tank 131. When the set time for the plastic part to be released in the conveying pipe 7 is reached, the control panel starts the electric telescopic rod 111 and the lifting motor 61 on the first conveying pipe 7 again, respectively, so that the receiving plate 9 and the corresponding receiving assembly move vertically upward to reset;

[0067] After the second plastic part is demoulded, the second plastic part enters the second conveying pipe 7 through the movable pipe 4, and the movable pipe 4 is quickly switched to the third conveying pipe 7, and then the second plastic part is stored in the same manner as above through the lifting assembly 6 and the material receiving assembly on the second conveying pipe 7. In this way, the subsequent plastic parts are stored in the same manner as above.

[0068] After all the storage slots 131 on the storage member 13 are used, the staff will take out the storage member 13 and replace it with a new storage member 13, and then proceed to the next round of work. During this process, the injection molding machine body 1 does not need to be stopped;

[0069] It should be noted that the number of plastic parts received in each round is determined by the number of storage slots 131. When the number of plastic parts produced exceeds the number of storage slots 131, it is necessary to replace new storage parts 13 for the next round of material storage. The material receiving assembly on the first conveying pipe 7 can be reset before the first plastic part of the next round falls into the first conveying pipe 7.

[0070] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
