Router upper shell body. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figures 1-6 In this embodiment of the utility model, a hot runner mold structure for a router upper shell flip-chip mold includes a mold body 10. The mold body 10 includes a core pad 11 and a moving mold base plate 12. A hot runner unit 13 is fixedly installed on the top of the moving mold base plate 12. A heavy-duty connector housing 20 is fixedly connected to one side of the core pad 11. A connector plug 21 is fixedly connected to one end of the heavy-duty connector housing 20. A protective sleeve 23 is slidably connected inside the heavy-duty connector housing 20. Two pressure rods 24 are movably arranged between the two inner walls of the protective sleeve 23. A control mechanism 26 for limiting the movement of the protective sleeve 23 is provided on the top of the heavy-duty connector housing 20.

[0022] Specifically, the protective sleeve 23 is made of polyethylene foam, which is lightweight, soft, and has good thermal insulation properties. It can prevent heat from being conducted from the mold to the inside of the connector. The protective sleeve 23 is slidably connected inside the heavy-duty connector housing 20. By pulling the pull block 261, the protective sleeve 23 can be exposed to contact the moving mold, preventing the wiring from being exposed and preventing dust from entering the inside of the connector. Rotating the bidirectional lead screw 243 can drive the two pressure rods 24 to come closer to each other to clamp and fix the connector wire harness, preventing the connector wire harness from shaking significantly during mold operation, protecting the connection of the wire harness, extending the service life of the connector, ensuring the stability of the electrical connection during mold operation, and facilitating use.

[0023] Example 1

[0024] like Figure 2-3 As shown, in this embodiment, two snap-fit ​​sleeves 211 are rotatably connected to the two outer walls of the connector plug 21, and ear plates 22 are fixed on both sides of the heavy-duty connector housing 20. Multiple fixing bolts 221 are movably snapped into the inside of the ear plates 22, and the fixing bolts 221 can be screwed into the core pad 11.

[0025] In this embodiment, when the connector plug 21 is wired, it is reinforced by snapping the snap sleeve 211 with the connector to prevent the connection from coming off. The fixing bolt 221 passes through the ear plate 22 and screws into the core pad 11 to stabilize and limit the heavy-duty connector housing 20.

[0026] like Figure 3-6 As shown, in this embodiment, both ends of the pressure rod 24 are fixedly connected to the shaft block 242, and multiple sliders 241 are slidably connected to both inner walls of the protective sleeve 23. The shaft block 242 is rotatably connected to the adjacent slider 241. A bidirectional lead screw 243 is rotatably connected between the inner walls of the protective sleeve 23. The bidirectional lead screw 243 passes through two adjacent sliders 241. The sliders 241 are screwed into the adjacent sections of the bidirectional lead screw 243. The top end of the bidirectional lead screw 243 passes through the protective sleeve 23 and extends to its outside. A torsion block 244 is fixedly sleeved on the top end of the bidirectional lead screw 243. A storage groove 254 is opened at one end of the heavy-duty connector housing 20.

[0027] In practice, two sliders 241 of uniform height are used to limit the rotation of the pressure rod 24, and the pressure rod 24 can slide up and down. The storage groove 254 is used to accommodate the torsion block 244 when the protective sleeve 23 is moved into the heavy-duty connector housing 20. When the protective sleeve 23 is exposed from the heavy-duty connector housing 20, the torsion block 244 is rotated to drive the bidirectional lead screw 243 to rotate, which can drive the two pressure rods 24 to move synchronously. The two pressure rods 24 are close to each other to fasten and clamp multiple wires to prevent damage caused by wire shaking during the operation of the mold body 10. The two pressure rods 24 are far apart from each other to facilitate maintenance and adjustment of the wire connection.

[0028] Example 2

[0029] Based on Embodiment 1, in order to facilitate the stable positioning of the protective sleeve 23 and to facilitate the driving of the two pressure rods 24 to fix the wire harness.

[0030] like Figure 1-5As shown, in this embodiment, the control mechanism 26 includes a pull block 261. A groove 25 is provided on the top of the heavy-duty connector housing 20. The pull block 261 is slidably connected to the inside of the groove 25, passing through the heavy-duty connector housing 20 and fixedly connected to the top of the protective sleeve 23. A horizontal plate 264 is fixedly connected to one side of the pull block 261, passing through the heavy-duty connector housing 20 and slidably connected thereto. A locking plate 262 is fixedly connected to both sides of the pull block 261. A slot 251 is provided on both inner walls of the groove 25, and the locking plate 262 can be movably engaged with the adjacent slot 251. The top of the heavy-duty connector housing 20 is provided with a limiting groove 252 and a notch 253 that are interconnected. A U-shaped rod 265 is slidably connected between the two inner walls of the limiting groove 252. Insert rods 266 are fixedly connected to both ends of the U-shaped rod 265. A slot 263 is provided at one end of the clamping plate 262. The insert rod 266 passes through the limiting groove 252 and is movably engaged with the adjacent slot 263. A limiting rod 267 is fixedly connected to one side of the U-shaped rod 265. The limiting rod 267 passes through the inner wall of the limiting groove 252 and is slidably connected to it. A spring 268 is fixedly connected between the U-shaped rod 265 and the heavy-duty connector housing 20.

[0031] In practical implementation, the sliding block 261 is slidably limited by the sliding groove 25, thereby limiting the sliding of the protective sleeve 23. The protective sleeve 23 protrudes until it contacts the core pad 11, which can block the gap between the heavy-duty connector housing 20 and the core pad 11, preventing debris and waste from entering the interior of the heavy-duty connector housing 20. The protective sleeve 23 moves into the interior of the heavy-duty connector housing 20 to facilitate the adjustment and maintenance of the wiring. The two slots 251, together with the locking plates 262, limit the movement range of the protective sleeve 23. The two locking plates 262 and the adjacent When the slot 251 is engaged, it corresponds to the two extreme positions of the protective sleeve 23. After the protective sleeve 23 is adjusted by moving the pull block 261, the spring 268 pushes the U-shaped rod 265 to move the insertion rod 266, so that the card plate 262 located inside the slot 251 engages with the adjacent insertion rod 266, thereby limiting the two extreme positions of the protective sleeve 23. This makes the protective sleeve 23 stable enough when it is exposed and stored, providing stable wiring protection for the heavy-duty connector housing 20, and making it more convenient to debug at the wiring point of the heavy-duty connector housing 20.
