Description

Technical Field

[0001] This utility model relates to the technical field of plastic product shells, specifically to an assembled plastic product shell. Background Technology

[0002] Plastic product casings refer to the external protective structures of products made primarily of plastic. Plastic is an excellent electrical insulator. This is particularly important in the application of electronic product casings; for example, the plastic casings of computer cases effectively prevent electric shock accidents when internal circuitry comes into contact with the human body.

[0003] While modern modular plastic product shells can be assembled, they are still not suitable for hollow products, requiring the creation of new molds and increasing production costs. Utility Model Content

[0004] The purpose of this utility model is to provide an assembled plastic product shell to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular plastic product shell, comprising a shell body, a lower mold, a hollow rod, a sealing plate, and an outer frame. Locking bolts are threaded onto both outer ends of the shell body, and an outer frame is movably inserted into one outer end of the shell body. An inner frame is movably inserted into the other outer end of the shell body. Fixing bolts are threaded onto both outer ends of the lower mold, and a connecting frame and a fixing frame are movably inserted into one outer end of the lower mold. Side plates are inserted into the inner walls of the lower mold and the shell body. A mounting frame is embedded and fixed inside the side plate, and an mounting groove is provided inside the mounting frame. A sealing groove is provided inside the sealing plate, and the sealing plate is threadedly connected to the outer surface of the hollow rod through the sealing groove.

[0006] When using the modular plastic product shell of this technical solution, a hollow rod of suitable diameter is selected according to the specific actual needs. The hollow rod is inserted into the shell body and the lower mold. Under the action of the power device, the outer rod drives the inner rod to move, and the inner rod drives the clamp to move. The clamp is moved to the outer surface of the hollow rod and can clamp the hollow rod. This mobility allows the clamp to adapt to hollow rods of different diameters. This design not only improves the versatility of the equipment, but also reduces the cost and time caused by changing clamps of different specifications. The hand-held sealing plate is connected to both sides of the hollow rod through the sealing groove thread, which facilitates sealing the shell body and the lower mold and facilitates the production of hollow workpieces. The sealing plate is connected to both sides of the hollow rod through the sealing groove thread, which facilitates quick assembly and disassembly. When maintenance or component replacement is required, operators can quickly disassemble the sealing plate for internal inspection or repair, and then reinstall it, greatly improving maintenance efficiency. The power unit drives the movement of the inner rod, enabling the fixture to quickly position and clamp the hollow rod, reducing manual adjustment time and increasing production speed. The fixture can accurately clamp the hollow rod, ensuring the stability and positional accuracy of the hollow rod during the production process, thereby improving the quality of the hollow workpieces produced.

[0007] Preferably, the front surface of the mounting bracket is threaded with a sealing cap, and the front surface of the sealing cap is welded with a handle. The handle welded to the front surface of the sealing cap provides a better grip, making it easier for the user to tighten or loosen the sealing cap.

[0008] Preferably, fixing plates are fixed to both outer end faces of the outer casing, and connecting plates are fixed to both outer end faces of the lower mold. The fixing plates significantly enhance the lateral stability of the outer casing. When subjected to external forces, the fixing plates can disperse and bear part of the force, preventing deformation or damage to the outer casing.

[0009] Preferably, the connecting plate and the fixing plate are internally threaded with locking rods, and both outer end faces of the locking rods are threaded with locking plates. The threaded locking rod and locking plate design makes the assembly and disassembly of the components very convenient. Users can quickly fix or loosen the components with a simple rotation action, without the need for complicated tools or operating procedures.

[0010] Preferably, an outer rod is fixed to the inner wall of the mounting groove, and an inner rod is movably inserted into one outer end face of the outer rod. This movable insertion design between the inner and outer rods allows the inner rod to move freely within a certain range while maintaining a tight connection with the outer rod.

[0011] Preferably, a clamp is fixed to one outer end face of the inner rod, and the hollow rod is held inside the clamp. The fixed connection between the inner rod and the clamp, and the clamp holding the hollow rod, form a stable structure.

[0012] Preferably, the upper surface of the outer shell is connected to a feed pipe, and the upper surface of the feed pipe has a feed inlet. The feed inlet is located on the upper surface of the feed pipe, which makes it more convenient to add materials.

[0013] Preferably, the feed inlet is internally threaded with a retaining cap, and a handle is welded to the upper surface of the retaining cap. The threaded retaining cap provides a good sealing effect, preventing material leakage or the entry of external impurities.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves the effect of facilitating the production of hollow workpieces by setting up a hollow rod, a sealing plate, and a clamp. A hollow rod of suitable diameter is selected according to specific actual needs. The hollow rod is inserted into the outer shell and the lower mold. Under the action of the power device, the outer rod drives the inner rod to move, and the inner rod drives the clamp to move, moving the clamp to the outer surface of the hollow rod. The clamp can clamp the hollow rod. This mobility allows the clamp to adapt to hollow rods of different diameters. This design not only improves the versatility of the equipment but also reduces the cost and time incurred by changing clamps of different specifications. The sealing plate is held by hand and connected to both sides of the hollow rod through the sealing groove thread, facilitating the sealing of the outer shell and the lower mold, thus facilitating the production of hollow workpieces. The sealing plate is connected to both sides of the hollow rod through the sealing groove thread, and this connection method facilitates quick assembly and disassembly.

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.

[0024] Example 1

[0025] Please see Figures 1 to 5 This utility model provides an embodiment of a modular plastic product shell, comprising a shell body 1, a lower mold 4, a hollow rod 11, a sealing plate 19, and an outer frame 21.

A sealing groove 18 is provided inside the sealing plate 19. The sealing plate 19 is threadedly connected to the outer surface of the hollow rod 11 through the sealing groove 18.

[0026] Of course, as is well known to those skilled in the art, the outer rod 16 of this utility model also needs to be provided with a power device to enable it to work normally. And as is well known to those skilled in the art, the provision of such power is commonplace and is a conventional means or common knowledge. It will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0027] Based on Embodiment 1, a modular plastic product shell is constructed. A hollow rod 11 of suitable diameter is selected according to the specific actual needs. The hollow rod 11 is inserted into the shell body 1 and the lower mold 4. The outer rod 16, under the action of a power device, drives the inner rod 15 to move. The inner rod 15 drives the clamp 14 to move, moving the clamp 14 to the outer surface of the hollow rod 11. The clamp 14 can clamp the hollow rod 11. This mobility allows the clamp 14 to adapt to hollow rods 11 of different diameters. This design not only improves the versatility of the equipment but also reduces the cost and time associated with replacing clamps 14 of different specifications. A hand-held sealing plate 19 is used, which is threaded onto both sides of the hollow rod 11 through a sealing groove 18. This facilitates sealing the shell body 1 and the lower mold 4, and facilitates the production of hollow workpieces. The sealing plate 19 is threaded onto both sides of the hollow rod 11 through the sealing groove 18, a connection method that allows for quick assembly and disassembly. When maintenance or replacement of parts is required, operators can quickly disassemble the sealing plate 19 for internal inspection or repair, and then reinstall it, which greatly improves maintenance efficiency. The power unit drives the movement of the inner rod 15, which enables the clamp 14 to quickly position and clamp the hollow rod 11, reducing the time for manual adjustment and increasing production speed. The clamp 14 can accurately clamp the hollow rod 11, ensuring the stability and positional accuracy of the hollow rod 11 during the production process, thereby improving the quality of the hollow workpieces produced.

[0028] Example 2

[0029] like Figures 1-5 As shown, the present invention proposes an assembled plastic product shell, which, compared to Embodiment 1, further includes a shell body 1, a lower mold 4, a hollow rod 11, a sealing plate 19, and an outer frame 21. A feed pipe 27 is connected to the upper surface of the shell body 1, and a feed inlet 24 is provided on the upper surface of the feed pipe 27. A fixing cover 26 is threadedly connected to the inside of the feed inlet 24, and a handle 25 is welded to the upper surface of the fixing cover 26. Locking bolts 22 are threadedly connected to the outer end faces of both sides of the shell body 1, and a movable insert is provided on one side of the outer end face of the shell body 1. An outer frame 21 is attached, and an inner frame 23 is movably inserted into the other outer end face of the outer shell body 1. Fixing bolts 20 are threadedly connected to both outer end faces of the lower mold 4. A connecting frame 10 is movably inserted into one outer end face of the lower mold 4, and a fixing frame 13 is movably inserted into one outer end face of the lower mold 4. Fixing plates 7 are fixed to both outer end faces of the outer shell body 1, and connecting plates 6 are fixed to both outer end faces of the lower mold 4. Locking rods 9 are threadedly connected to the inside of the connecting plate 6 and the fixing plate 7, and locking plates 8 are threadedly connected to both outer end faces of the locking rods 9.

[0030] In this embodiment, by loosening the fixing bolt 20, holding the connecting frame 10 and the fixing frame 13 by hand, and stretching the connecting frame 10 and the fixing frame 13 by hand, the lower mold 4 is stretched to a suitable diameter according to specific actual needs.

Then, by holding the outer frame 21 and the inner frame 23 by hand, and stretching the outer frame 21 and the inner frame 23 by hand, the outer shell body 1 is stretched to a suitable diameter according to specific actual needs. Finally, the locking bolt 22 is tightened. By loosening the fixing bolt 20 and the locking bolt 22, the diameters of the lower mold 4 and the outer shell body 1 can be adjusted respectively to adapt to different production requirements. This adjustability allows the equipment to flexibly handle workpieces of various sizes without replacing the lower mold 4 or the outer shell body 1, greatly improving the equipment's performance. The versatility and economy of the design allow for the bonding of the outer shell 1 and the lower mold 4, the bonding of the fixing plate 7 and the connecting plate 6, the threaded connection of the locking rod 9 to the inside of the fixing plate 7 and the connecting plate 6, and the threaded connection of the locking plate 8 to the outer end faces of both sides of the locking rod 9. This allows for the assembly of the outer shell 1. After the fixing plate 7 and the connecting plate 6 are bonded together, they are fixed by the locking rod 9 and the locking plate 8, further enhancing the stability of the entire structure and ensuring that the equipment can maintain a stable operating state during production. The threaded connection of the locking rod 9 and the locking plate 8 provides a reliable connection, ensuring the stability of the outer shell 1 and the lower mold 4 during production. This connection method can withstand greater external forces and prevent the components from loosening or separating during use.
