Description

Technical Field

[0001] This utility model relates to the field of plastic molds, and in particular to a mold for a split-type router plastic shell. Background Technology

[0002] A split-type router, also known as a parent-child router, is a special type of wireless router. It consists of a main router and at least one extension router. The main purpose of this design is to increase the coverage of Wi-Fi signals, especially in large houses, villas, or environments with signal blind spots.

[0003] Currently, most existing split-type router shells are manufactured using injection molding. A search reveals Chinese Patent Publication No. CN218366244U, which discloses a plastic shell mold for a split-type router. This mold includes a lower mold with a second slot on its inner wall. An upper mold is movably connected to the top of the lower mold, with an injection hole on its inner wall and a first slot on its top. A dust-proof mechanism is movably installed on the top of the upper mold, and a second locking block is fixedly connected to the bottom. The lower mold also has a second slot on its top and an ejector mechanism is movably installed at its bottom. This ejector mechanism activates a motor, which drives a bidirectional threaded rod to rotate. The rotation of the threaded rod causes the threaded sleeve to move in opposite directions, which in turn causes the movable rod to move in opposite directions, raising the connecting plate. This, in turn, causes the ejector rod and ejector plate to rise, ejecting the injection mold. This facilitates mold removal, solving the problem of time-consuming and laborious mold removal and meeting user needs.

[0004] Although the above-mentioned application documents can achieve the effect of ejecting injection molds, in actual use, since ejecting the finished product requires the assistance of other driving components, it is impossible to guarantee the time difference between its start-up time and the time after mold opening. Therefore, when it is necessary to mass-produce split router plastic shells, it is often necessary to wait for the workers to shake and start the ejection mechanism and remove the shell before the next mold can be produced, which affects production efficiency. To address this issue, a split router plastic shell mold is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a split router plastic shell mold, which aims to improve the problem that the shell model needs to be controlled by workers to eject after cooling, which is not convenient for mass production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of a mold for a split router plastic shell, including a mounting frame 1, a lower mold 2 disposed inside the mounting frame 1, an upper mold 3 slidably connected to the inner wall of the mounting frame 1, and after the upper mold 3 and the lower mold 2 are closed, the shape of the gap between the two is the same as the shape required for the split router plastic shell, and a cylinder 4 is fixedly connected to the top of the mounting frame 1, the output shaft of the cylinder 4 can move up and down, and the output shaft of the cylinder 4 is fixedly connected to the top of the upper mold 3.

[0035] Reference Figure 2 and Figure 3The bottom of the upper mold 3 and the interior of the lower mold 2 are jointly provided with an ejection mechanism 5. The ejection mechanism 5 includes a slide 51, which is cylindrical in shape and is located inside the lower mold 2. A moving block 52 is slidably connected to the inner wall of the slide 51. The moving block 52 is semi-cylindrical in shape and its height is lower than the vertical depth of the slide 51. A pneumatic pipe 53 is connected through and fixed to the inner wall of the moving block 52. The pneumatic pipe 53 is L-shaped and a pushing block 54 is piston-connected to the inner wall of the pneumatic pipe 53. The moving direction of the pushing block 54 relative to the pneumatic pipe 53 is left and right.

[0036] Reference Figure 2 - Figure 4 The inner wall of the air pressure pipe 53 is connected to a piston-like pressure block 55. The pressure block 55 moves up and down relative to the air pressure pipe 53. The shape of the air pressure pipe 53 ensures that the pressure block 55 can drive the push block 54 to move horizontally after being subjected to force in the vertical direction. The bottom end of the upper mold 3 is fixedly connected to an insert rod 56. The insert rod 56 is semi-cylindrical, and its diameter matches the diameter of the slide groove 51. The top view of the insert rod 56 and the moving block 52 can form a complete circle. The inner wall of the insert rod 56 is provided with a sliding groove 57. The inner wall of the sliding groove 57 is slidably connected to a locking block 58. The bottom of the locking block 58 near the outer side of the lower mold 2 is provided with an inclined chamfer. The outer wall of the locking block 58 and the inner wall of the sliding groove 57 are elastically connected by a spring 59. One end of the spring 59 is fixedly connected to the outer wall of the locking block 58, and the other end of the spring 59 is fixedly connected to the inner wall of the sliding groove 57.

[0037] Reference Figure 2 and Figure 5The bottom end of the movable block 52 is fixedly connected to a connecting rod 511, the bottom end of the connecting rod 511 is fixedly connected to a connecting plate 512, and the top end of the connecting plate 512 is fixedly connected to a push rod 513. The push rod 513 is set in the recess of the lower mold 2, and when the push rod 513 is at its lowest position, its upper surface is exactly flush with the recess of the lower mold 2. Through the setting of the installation position, it is ensured that the push rod 513 will not affect the normal injection molding effect. The outer wall of the connecting plate 512 is slidably connected to the inner wall of the lower mold 2. The ejection mechanism 5 also includes a positioning block 510. The positioning block 510 is semi-cylindrical in shape, and a groove is opened inside the positioning block 510. The bottom of the groove is shaped like a... The groove is a semi-circle with a diameter greater than that of the groove 51. The groove inside the positioning block 510 is gradually deformed. The shape of the positioning block 510 ensures that the insertion rod 56 can smoothly enter the interior of the positioning block 510. During the descent, the gradual change of the inner wall of the positioning block 510 ensures that it can enter the groove 51. The positioning block 510 is fixedly connected to the top of the lower mold 2. The bottom of the upper mold 3 has a groove with a shape that matches the shape of the positioning block 510. The groove ensures that the positioning block 510 can enter the groove when the upper mold 3 and the lower mold 2 are closed, thus ensuring smooth mold closing.

[0038] Reference Figure 5 - Figure 7 The mounting frame 1 and the lower mold 2 are both equipped with a rotating mechanism 6. The rotating mechanism 6 includes a pneumatic strip 61. The inner wall of the pneumatic strip 61 is fixedly connected to the inner wall of the mounting frame 1. The outer wall of the pneumatic strip 61 is fixedly connected to a pneumatic box 62. Both the pneumatic box 62 and the pneumatic strip 61 are made of materials with good sealing properties. The interior of the pneumatic box 62 is connected to the interior of the pneumatic strip 61. The inner wall of the pneumatic box 62 is piston-connected to a control block 63. The lower surface area of ​​the control block 63 is larger than the cross-sectional area of ​​the pneumatic strip 61. The top of the control block 63 is elastically connected to the inner wall of the pneumatic box 62 by a second spring 64. One end of the second spring 64 is fixedly connected to the top of the control block 63, and the other end of the second spring 64 is fixedly connected to the inner wall of the pneumatic box 62. The inner wall of the pneumatic strip 61 is piston-connected to a moving strip 65. The outer wall of the moving strip 65 is in contact with the inner wall of the pneumatic strip 61, and the moving direction of the moving strip 65 is the front-back direction.

[0039] Reference Figure 5 - Figure 7 A control ball 66 is fixedly connected to the outer wall of the moving strip 65, and a rotating shaft 67 is fixedly connected to the outer wall of the lower mold 2. The outer wall of the rotating shaft 67 is rotatably connected to the inner side of the mounting frame 1. A control groove 68 is provided on the inner wall of the rotating shaft 67. The shape of the control groove 68 is spiral, and the number of spiral turns of the control groove 68 is half a turn. By setting the number of turns, it is ensured that the rotating shaft 67 can drive the lower mold 2 to rotate half a turn. A storage groove 7 is provided on the inner wall of the mounting frame 1.

[0040] Working principle: When in use, during mold closing, the insert rod 56 first enters the larger diameter area above the positioning block 510. Since the upper opening of the positioning block 510 is larger than the bottom surface of the insert rod 56, even if there is a slight deviation between the upper mold 3 and the lower mold 2, the positioning block 510 can still enter smoothly.

[0041] As the upper mold 3 continues to move downward, the insert rod 56 moves to a position matching the lower mold 2 under the control of the inner wall of the positioning block 510, thus ensuring smooth mold closing.

[0042] Meanwhile, as the insertion rod 56 enters the slide groove 51, the inclined surface of the locking block 58 is subjected to force, causing the locking block 58 to enter the interior of the slide groove 57. When the insertion rod 56 moves to the bottom, the locking block 58 is at the same horizontal position as the groove of the moving block 52. Therefore, under the elastic force of the spring 59, the locking block 58 enters the recessed position of the moving block 52, and pushes the pushing block 54, increasing the area of ​​the pushing block 54 inside the air pressure pipe 53, thereby causing the pressure block 55 to move upward.

[0043] When the mold is opened, the cylinder 4 drives the upper mold 3 to move upward, and the insert rod 56 drives the locking block 58 to move upward. Because the locking block 58 is in the recessed position of the moving block 52 at this time, the locking block 58 drives the moving block 52 to move upward, which in turn causes the moving block 52 to drive the connecting rod 511 to move upward, which in turn causes the connecting rod 511 to drive the connecting plate 512 to move upward, which in turn causes the connecting plate 512 to drive the ejector rod 513 to move upward, thereby achieving the effect of ejecting the finished product.

[0044] When the moving block 52 moves to the point where the pressure block 55 contacts the inner wall of the slide groove 51, the pressure block 55 enters the air pressure pipe 53, which causes the pushing block 54 to push the locking block 58 under the action of air pressure, thereby causing the locking block 58 to leave the inner groove of the moving block 52, thus separating the moving block 52 from the insertion rod 56.

[0045] As the upper mold 3 continues to move upward until it pushes the control block 63, the control block 63 moves upward due to the force and enters the air pressure box 62. This causes the gas inside the air pressure box 62 to enter the air pressure bar 61, which in turn causes the moving bar 65 to move forward under the action of air pressure, and drives the control ball 66 to move forward.

[0046] As the control ball 66 moves forward, it presses against the inner wall of the control groove 68, causing the control groove 68 to overlap with the area in the same position in the front-back direction, thereby driving the rotating shaft 67 to rotate. This causes the rotating shaft 67 to drive the lower mold 2 to rotate. Since the finished product is in the ejected state at this time, after the lower mold 2 flips over, the finished product can fall into the storage groove 7, thus facilitating continuous production of the equipment.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
