Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for forming a shielding shell for a coaxial connector. Background Technology

[0002] Against the backdrop of the rapid development of modern electronic communication technology, coaxial connectors, as key components for achieving stable signal transmission, are widely used in aerospace, communication base stations, radar systems, and other fields. The quality of their shielding shells directly affects the electrical performance, anti-interference ability, and service life of the connectors. Traditional coaxial connector shielding shell molding dies have revealed many problems in actual production. On the one hand, the mold support device has limitations. When removing the shielding shell after mold opening, the upper mold lacks reliable support, which not only affects production efficiency but also easily leads to safety hazards. On the other hand, the mold's guide structure design is not reasonable enough. If there is a lack of effective lubrication, the guide components are prone to excessive wear and frictional heat, resulting in a decrease in precision and causing defects such as dimensional deviations and poor surface quality in the molded shielding shells.

[0003] Chinese patent application CN202322293297.2 discloses a molding die. The key technical points are: In this invention, the worker inserts a material model into the die body. After insertion, the inner wall of the model presses against the adjusting rod and the abutment. An adjusting component causes the pressed adjusting rod and the abutment to rotate and retract into the slot. The retracted abutment then presses against a pressure sensor. If the pressure sensor in the slot on one side of the die body does not detect a pressure signal, it indicates that the model does not match the die body's dimensions. An external alarm sounds, reminding the worker to check and handle the situation promptly. After processing is complete and the model is removed, the adjusting component's return spring causes the adjusting rod and the abutment to spring back to their original positions, allowing for the next processing step, thus increasing the device's practicality.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: when the operator removes the connector shielding shell, the upper mold does not have suitable support, and the upper mold slides down along the guide rod, causing the operator to have to hold the upper mold with one hand, which makes it inconvenient for the operator to remove the connector shielding shell; therefore, in order to solve the above problems, a coaxial connector shielding shell forming mold is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where the upper mold does not have suitable support and slides down along the guide rod, forcing workers to hold the upper mold with one hand, which makes it inconvenient for workers to remove the connector shielding shell. Therefore, this invention proposes a coaxial connector shielding shell forming mold.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coaxial connector shield shell forming mold, comprising an upper mold and a lower mold, wherein a guide rod is installed on the surface of the lower mold, and the arc surface of the guide rod is slidably connected to the upper mold; a support device is provided on the surface of the upper mold, the support device comprising eight rotating blocks, all eight rotating blocks being fixedly connected to the surface of the upper mold; the eight rotating blocks are arranged in pairs, and a rotating rod is rotatably connected to the side of two rotating blocks that are close to each other; a square rod is fixedly connected to the arc surface of the rotating rod; a groove is provided on the surface of the square rod; a sliding rod is slidably connected to the surface of the groove of the square rod; and four fixing blocks are fixedly connected to the surface of the lower mold, each of the four fixing blocks having a fixing groove.

[0007] The effect achieved by the above-mentioned components is as follows: by setting up a support device, the upper mold can be supported, which avoids the situation where the upper mold does not have a suitable support when the operator removes the connector shielding shell, and the upper mold slides down along the guide rod, causing the operator to have to hold the upper mold with one hand, thus making it inconvenient for the operator to remove the connector shielding shell, thereby improving the practicality of the equipment.

[0008] Preferably, a fixed rod is fixedly connected to the surface of the square rod, an operating plate is slidably connected to the arc surface of the fixed rod, an insert rod is fixedly connected to the side of the operating plate near the square rod, and several slots are opened on the surface of the sliding rod.

[0009] The aforementioned components achieve the following effect: they facilitate the adjustment of the length of the sliding rod by the operator, thereby allowing the operator to adjust the support distance between the upper and lower molds.

[0010] Preferably, a spring is fitted onto the arc surface of the fixing rod, and the two ends of the spring are fixedly connected to the operating plate and the square rod, respectively.

[0011] The effect achieved by the above components is that the spring's rebound force automatically inserts the plug rod, while limiting the movement of the plug rod driven by the control panel, thus improving the stability of the plug rod when it is fixed to the sliding rod.

[0012] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the rotating block and the square rod, respectively.

[0013] The effect achieved by the above components is that the torsion spring's torque automatically opens the square rod, preventing the square rod from falling due to gravity and causing the sliding rod to collide with the fixed block when the upper mold moves downward.

[0014] Preferably, both rotating blocks have grooves on their surfaces, and limiting blocks are fixedly connected to the surfaces of the grooves of the two rotating blocks.

[0015] The effect achieved by the above components is that the limiting block can limit the opening angle of the square rod, thus preventing the torsion spring from causing the square rod to rotate too much and occupying too much space.

[0016] Preferably, the surface of the upper mold is provided with a lubrication device, which includes a U-shaped block, the U-shaped block is fixedly connected to the surface of the upper mold, a lubrication pad is slidably connected to the surface of the U-shaped block, the lubrication pad is slidably connected to the arc surface of the guide rod, and a square plate is fixedly connected to the surface of the lubrication pad.

[0017] The effect achieved by the above components is as follows: by setting up a lubrication device, the guide rod can be lubricated, which avoids the situation where the upper mold and the guide rod have large friction due to the lack of proper lubrication during long-term use, resulting in increased wear between the upper mold and the guide rod, thus improving the practicality of the equipment.

[0018] Preferably, two connecting rods are fixedly connected to the surface of the U-shaped block, and a connecting plate is fixedly connected to the end of the connecting rod away from the U-shaped block. A limiting rod is slidably inserted into the connecting plate, and two limiting grooves are opened on the surface of the square plate.

[0019] The above-mentioned components achieve the following effect: they facilitate the disassembly and replacement of the lubricating pads by staff, avoiding the situation where the lubricating pads are damaged and it is inconvenient for staff to replace them with new ones, thus preventing a reduction in the lubrication effect of the lubricating pads.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting a support device, the upper mold can be supported, which avoids the situation where the upper mold does not have a suitable support when the operator removes the connector shielding shell, and the upper mold slides down along the guide rod, causing the operator to have to hold the upper mold with one hand, thus making it inconvenient for the operator to remove the connector shielding shell, thereby improving the practicality of the equipment.

[0022] 2. In this utility model, by setting a lubrication device, the guide rod can be lubricated, which avoids the situation where the upper mold and the guide rod have large friction due to the lack of proper lubrication during long-term use, resulting in increased wear between the upper mold and the guide rod, thus improving the practicality of the equipment.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a coaxial connector shield shell forming mold, including an upper mold 1 and a lower mold 2. A guide rod 5 is installed on the surface of the lower mold 2, and the arc surface of the guide rod 5 is slidably connected to the upper mold 1. A support device 3 is provided on the surface of the upper mold 1. By setting the support device 3, the upper mold 1 can be supported, avoiding the situation where the upper mold 1 does not have proper support when the operator removes the connector shield shell, and the upper mold 1 slides down along the guide rod 5, causing the operator to have to hold the upper mold 1 with one hand, thus making it inconvenient for the operator to remove the connector shield shell. This improves the practicality of the equipment. A lubrication device 4 is provided on the surface of the upper mold 1, which can lubricate the guide rod 5. This avoids the situation where the guide rod 5 does not have proper lubrication during long-term use, resulting in large friction between the upper mold 1 and the guide rod 5, causing increased wear between the upper mold 1 and the guide rod 5. This also improves the practicality of the equipment.

[0031] The specific setup and function of its support device 3 and lubrication device 4 will be described in detail below.

[0032] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the support device 3 includes eight rotating blocks 301, all of which are fixedly connected to the surface of the upper mold 1. The eight rotating blocks 301 are arranged in pairs, and a rotating rod 302 is rotatably connected to the side of two rotating blocks 301 that are close to each other. A square rod 303 is fixedly connected to the arc surface of the rotating rod 302. A groove is formed on the surface of the square rod 303, and a sliding rod 304 is slidably connected to the surface of the groove of the square rod 303. Four fixing blocks 305 are fixedly connected to the surface of the lower mold 2, and fixing grooves are formed on the surface of each of the four fixing blocks 305. A fixing rod 306 is fixedly connected to the surface of the square rod 303, and an operating plate 307 is slidably connected to the arc surface of the fixing rod 306. The side of the operating plate 307 that is close to the square rod 303 is... A fixed connection is provided with a plug rod 308, and the surface of the sliding rod 304 has several slots. When the operator needs to remove the processed connector shielding shell, the upper mold 1 can be moved. The upper mold 1 moves along the arc surface of the guide rod 5. When the upper mold 1 moves to the appropriate position, it separates from the lower mold 2. The square rod 303 is rotated, which drives the rotating rod 302 to rotate. The square rod 303 drives the sliding rod 304 to move. When the square rod 303 moves to the appropriate position, the sliding rod 304 is located directly above the fixing slot of the fixing block 305. The upper mold 1 is moved until the sliding rod 304 moves to the surface of the fixing slot of the fixing block 305. At this point, the operator can remove the processed connector shielding shell. When adjusting the support distance between the upper mold 1 and the lower mold 2, the length of the sliding rod 304 can be adjusted to obtain different support distances. Pulling the operating plate 307 causes the insertion rod 308 to move. When the insertion rod 308 is completely disengaged from the surface of the slot of the sliding rod 304, the insertion rod 308 releases its fixation to the sliding rod 304. Moving the sliding rod 304, it slides on the surface of the groove of the square rod 303. When the sliding rod 304 moves to the appropriate position, pushing the operating plate 307 causes the insertion rod 308 to move. When the insertion rod 308 is inserted into the surface of the slot of the sliding rod 304, the insertion rod 308 can fix the sliding rod 304, achieving the effect of conveniently adjusting the length of the sliding rod 304 for the operator. This allows the operator to adjust the support distance between the upper mold 1 and the lower mold 2. A spring 309 is fitted onto the arc surface of the fixing rod 306. The two ends of the spring 309 are fixedly connected to the operating plate 307 and the square rod 303, respectively. When the operator pulls the operating plate 307, the spring 309 is stretched, causing the operating plate 307 to move the insertion rod 308. When the insertion rod 308 is completely disengaged from the surface of the sliding rod 304 slot, the insertion rod 308 is released from its fixation to the sliding rod 304. At this point, the operator can adjust the length of the sliding rod 304. After adjustment, the operating plate 307 is released, and the rebound force of the spring 309 causes the operating plate 307 to move, which in turn causes the insertion rod 308 to move until the insertion rod 308 is inserted into the surface of the sliding rod 304 slot.The rebound force of spring 309 achieves the effect of automatically inserting the insertion rod 308, while also limiting the movement of the insertion rod 308 driven by the operating plate 307, thus improving the stability of the insertion rod 308 when fixing the sliding rod 304. Two torsion springs 310 are sleeved on the arc surface of the rotating rod 302, with their ends fixedly connected to the rotating block 301 and the square rod 303, respectively. When the operator needs to use the upper mold 1 and lower mold 2 to produce connector shielding shells, the upper mold 1 is first moved upwards, sliding on the arc surface of the guide rod 5. When the sliding rod 304 completely disengages from the surface of the fixing slot of the fixing block 305, the torque of the torsion spring 310 drives the square rod 303 to rotate, which in turn drives the rotating rod 302 to rotate until the square rod 303 reaches the appropriate position. At this point, the operator can move the upper mold 1 downwards until it moves to the surface of the lower mold 2. The operator can then use the upper mold 1 and lower mold 2 to produce connector shielding shells. The torque of the torsion spring 310 achieves the effect of automatically opening the square rod 303. To prevent the square rod 303 from falling due to gravity and causing the sliding rod 304 to collide with the fixed block 305 when the upper mold 1 moves downward, grooves are provided on the surfaces of both rotating blocks 301. Restricting blocks 311 are fixedly connected to the surfaces of these grooves. When the operator needs to move the upper mold 1 to the surface of the lower mold 2, the upper mold 1 is first moved upward. When the sliding rod 304 completely disengages from the surface of the fixed groove of the fixed block 305, the torque of the torsion spring 310 drives the square rod 303 to rotate. The square rod 303 then drives the rotating rod 302 to rotate until the surface of the square rod 303 contacts the restricting block 311. At this point, the square rod 303 has moved to the appropriate position, and the operator can then move the upper mold 1 downward until it reaches the surface of the lower mold 2. The restricting block 311 effectively limits the opening angle of the square rod 303, preventing the torsion spring 310 from causing the square rod 303 to rotate too much and occupy too much space.

[0033] Reference Figure 5 and Figure 6As shown, specifically, the lubrication device 4 includes a U-shaped block 41, which is fixedly connected to the surface of the upper mold 1. A lubricating pad 42 is slidably connected to the surface of the U-shaped block 41, and the lubricating pad 42 is slidably connected to the arc surface of the guide rod 5. A square plate 43 is fixedly connected to the surface of the lubricating pad 42. Two connecting rods 44 are fixedly connected to the surface of the U-shaped block 41. A connecting plate 45 is fixedly connected to the end of the connecting rod 44 away from the U-shaped block 41. A limiting rod 46 is slidably inserted into the connecting plate 45. Two limiting grooves are opened on the surface of the square plate 43. When the operator moves the upper mold 1, the upper mold 1 drives the lubricating pad 42 to slide on the arc surface of the guide rod 5. The lubricating pad 42 can lubricate the guide rod 5, thereby reducing the friction between the upper mold 1 and the guide rod 5. When the lubricating pad 42 is damaged after long-term use, the operator can replace it with a new one. When the lubricating pad 42 is pulled, the limiting rod 46 slides within the connecting plate 45. When the limiting rod 46 is completely disengaged from the surface of the limiting groove of the square plate 43, the limiting rod 46 releases its fixation on the square plate 43, allowing the square plate 43 to move. The square plate 43 then moves the lubricating pad 42. When the lubricating pad 42 is completely disengaged from the surface of the U-shaped block 41, the lubricating pad 42 is disassembled. At this point, the operator can replace the lubricating pad 42 by placing the new lubricating pad 42 on the surface of the U-shaped block 41 and pushing the limiting rod 46 until it is inserted into the surface of the limiting groove of the square plate 43. At this point, the limiting rod 46 can fix the square plate 43, achieving the effect of facilitating the operator to disassemble and replace the lubricating pad 42. This avoids the situation where the lubricating pad 42 is damaged and it is inconvenient for the operator to replace it with a new one, which could lead to a reduction in the lubrication effect of the lubricating pad 42.

[0034] Working principle: When the operator needs to remove the processed connector shielding shell, the upper mold 1 can be moved. The upper mold 1 moves along the arc surface of the guide rod 5. When the upper mold 1 moves to the appropriate position, it separates from the lower mold 2. The square rod 303 is rotated, which drives the rotating rod 302 to rotate. The square rod 303 drives the sliding rod 304 to move. When the square rod 303 moves to the appropriate position, the sliding rod 304 is located directly above the fixing groove of the fixing block 305. The upper mold 1 is moved until the sliding rod 304 moves to the fixing block. On the surface of the 305 fixing slot, the operator can remove the processed connector shielding shell. When the operator needs to adjust the support distance between the upper mold 1 and the lower mold 2, the length of the sliding rod 304 can be adjusted to obtain different support distances. Pulling the operating plate 307 stretches the spring 309, and the operating plate 307 drives the insertion rod 308 to move. When the insertion rod 308 is completely disengaged from the surface of the sliding rod 304 slot, the insertion rod 308 is released from fixing the sliding rod 304. Moving the sliding rod 304, the sliding rod 304 slides on the surface of the square rod 303 groove. When the sliding rod 304 moves to the appropriate position, the operating plate 307 is released. The rebound force of the spring 309 drives the operating plate 307 to move, which in turn drives the insertion rod 308 to move. When the insertion rod 308 is inserted into the surface of the slot of the sliding rod 304, the insertion rod 308 can fix the sliding rod 304. When the operator needs to move the upper mold 1 to the surface of the lower mold 2, the upper mold 1 is moved upward first. When the sliding rod 304 is completely disengaged from the surface of the fixing slot of the fixing block 305, the torque of the torsion spring 310 drives the square rod 303 to rotate. Rotate the rotating rod 302 until the surface of the square rod 303 contacts the limiting block 311. At this time, the square rod 303 moves to a suitable position, and the operator can move the upper mold 1 downward until the upper mold 1 moves to the surface of the lower mold 2. This achieves the effect of supporting the upper mold 1, avoiding the situation where the upper mold 1 does not have a suitable support when the operator removes the connector shielding shell, and the upper mold 1 slides down along the guide rod 5, causing the operator to have to hold the upper mold 1 with one hand, which makes it inconvenient for the operator to remove the connector shielding shell.

[0035] When the operator moves the upper mold 1, the upper mold 1 causes the lubricating pad 42 to slide on the arc surface of the guide rod 5. The lubricating pad 42 lubricates the guide rod 5, thereby reducing the friction between the upper mold 1 and the guide rod 5. When the lubricating pad 42 is damaged after long-term use, the operator can replace it with a new one. Pulling the limiting rod 46 causes it to slide within the connecting plate 45. When the limiting rod 46 is completely disengaged from the surface of the limiting groove of the square plate 43, it releases its fixation to the square plate 43. Moving the square plate 43 causes the lubricating pad 42 to move. When the lubricating pad 42 is completely disengaged from the surface of the limiting groove of the square plate 43, it releases its fixation to the square plate 43. Moving the square plate 43 causes the lubricating pad 42 to move. When the U-shaped block 41 is removed from the surface, the lubricating pad 42 is completely removed. At this time, the operator can replace the lubricating pad 42 with a new one. Place the new lubricating pad 42 on the surface of the U-shaped block 41 and push the limiting rod 46 until the limiting rod 46 is inserted into the surface of the limiting groove of the square plate 43. At this time, the limiting rod 46 can fix the square plate 43. This achieves the effect of lubricating the guide rod 5, avoiding the situation where the guide rod 5 does not have proper lubrication during long-term use, resulting in large friction between the upper mold 1 and the guide rod 5, which would cause increased wear between the upper mold 1 and the guide rod 5.
