Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an injection mold structure for an ink cartridge of a copier. Background Art

[0002] Injection molds are jigs used for the rapid prototyping of plastic products. They consist of two parts: a movable mold and a fixed mold. The movable mold is mounted on the moving platen of the injection molding machine, while the fixed mold is mounted on the fixed platen. During injection molding, the movable and fixed molds close together to form the gating system and the mold cavity. When the mold is opened, the movable and fixed molds separate to facilitate the removal of the plastic product. The mold primarily consists of a gating system, a temperature control system, molding components, and structural parts. The gating system and molding components are in direct contact with the plastic and change with the plastic and the product. They are the most complex and variable parts of the mold, requiring the highest machining finish and precision. The gating system refers to the flow path of the plastic before it enters the mold cavity from the nozzle, and includes the main runner, cold well, branch runners, and gate. Molding components are the various components that contribute to the product's shape, including the movable mold, fixed mold, mold cavity, core, molding rod, and vent.

[0003] The ink cartridge assembly consists of an upper cover, ink cartridge, piston body, and lower cover. For use, the upper cover is removed, and the cartridge mouth is docked with the ink inlet of a copier or printer. When the copier is in operation, as the ink gradually decreases, a certain negative pressure forms within the cartridge, causing the piston body to move upward. When the ink is exhausted, the piston body moves up to the top of the cartridge body. Because one end of the ink cartridge is threaded, common ink cartridge injection molds typically utilize a two-piece (half-piece) mold structure to facilitate stripping. However, this two-piece cavity creates two axial parting lines on the cartridge's outer surface, reducing the cartridge's surface quality. Therefore, we propose a copier ink cartridge injection mold structure to address this issue. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides an injection mold structure for an ink cartridge of a copier, which has the advantages of facilitating stripping and improving surface quality, and solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: the ink cartridge injection mold structure of the copier includes a static template base and a movable template base, the top of the static template base is fixedly installed with a molding static template, and the interior of the molding static template is provided with evenly distributed molding cavities, and the inner side of the molding cavity is provided with a molding core, the movable template base is located above the molding static template, the bottom of the movable template base is fixedly installed with a molding movable template, and the bottom of the molding movable template is provided with two sets of adjustment mechanisms, the side of the molding movable template is inlaid with a driving motor, and the output shaft of the driving motor is fixedly sleeved with an active synchronous wheel, and the outer side of the active synchronous wheel is movably sleeved with a transmission synchronous belt.

[0006] Preferably, the two groups of adjustment mechanisms are mirror-imaged and distributed at the bottom of the forming movable template. The adjustment mechanism includes an adjusting screw, a thread forming clamping plate, and a thread forming cavity. One end of the thread forming clamping plate is fixedly connected to a connecting ear, and the connecting ear is threadedly connected to the adjusting screw. The number of connecting ears and thread forming clamping plates outside a single adjusting screw is two groups. The front and rear sides of the outside of the adjusting screw are provided with threads that cooperate with the two groups of connecting ears and are counter-rotating to each other.

[0007] Preferably, a center positioning block is fixedly installed on the bottom of the forming movable template, and the center positioning block is movably connected to the adjusting screw rods in the two groups of adjusting mechanisms, and the adjusting screw rods in the two groups of adjusting mechanisms are fixedly connected.

[0009] Preferably, the end of the thread forming clamping plate away from the connecting ear is fixedly connected to a guide slider, the bottom of the forming movable template is fixedly installed with a guide rail, and the guide rail is movably connected to the guide slider.

[0010] Preferably, an injection port is provided on the top of the movable template base, an injection hole cooperating with the molding cavity is opened on the bottom of the molding movable template, and an injection flow channel communicating with the injection port is opened on the top of the molding movable template.

[0011] The present invention provides an ink cartridge injection mold structure for a copier, which has the following beneficial effects:

[0012] 1. The ink cartridge injection mold structure of this copier can be integrated with the molding cavity and molding core to form an integral structure, so that the main part of the ink cartridge can be integrally molded, thereby improving the surface quality of the ink cartridge. In addition, when the ink cartridge is removed, the driving motor drives the active synchronous wheel, the driven synchronous wheel, and the two sets of adjustment screws to rotate, which can simultaneously drive the threaded forming clamping plates in the two sets of adjustment mechanisms to move, removing the restriction on the thread structure at the end of the ink cartridge and facilitating the removal of the ink cartridge.

[0013] 2. The ink cartridge injection mold structure of the copier is equipped with multiple adjustment mechanisms and counter-rotating threads that cooperate with the connecting ears on the adjustment screw. When the adjustment screw rotates, it can synchronously drive multiple thread-forming pallets to move, so that the mold can inject multiple ink cartridges at a time, improving injection molding efficiency. In addition, when the thread-forming pallets move, the guide slider and guide rail cooperate to limit the movement, ensuring the stability of the adjustment mechanism during operation.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1 and 2The present invention provides a technical solution: an injection mold structure for an ink cartridge of a copier, comprising a static die plate base 1 and a movable die plate base 3. A molding static die plate 2 is fixedly mounted on the top of the static die plate base 1, and a uniformly distributed molding cavity 5 is defined within the interior of the molding static die plate 2. A molding core 6 is disposed within the molding cavity 5. By configuring the molding cavity 5 and the molding core 6 as an integral structure, the main portion of the ink cartridge can be integrally molded, thereby improving the surface quality of the ink cartridge. The movable die plate base 3 is located above the molding static die plate 2. A molding movable die plate 4 is fixedly mounted on the bottom of the movable die plate base 3, and two sets of adjustment mechanisms 7 are disposed at the bottom of the molding movable die plate 4. A drive motor 9 is embedded in the side of the molding movable die plate 4, and an active synchronous pulley 10 is fixedly mounted on the output shaft of the drive motor 9. A transmission timing belt 12 is movably mounted on the exterior of the active synchronous pulley 10. The drive motor 9 drives the active synchronous pulley 10, the driven synchronous pulley 11, and the two sets of adjustment screws 71 to rotate, thereby simultaneously driving the threaded molding clamps 72 in the two sets of adjustment mechanisms 7 to move, thereby removing the restriction on the threaded structure at the end of the ink cartridge and facilitating ink cartridge removal.

[0022] See also Figure 3 and 4 , two sets of adjustment mechanisms 7 are mirror-imaged and distributed at the bottom of the movable molding plate 4. The adjustment mechanism 7 includes an adjusting screw 71, a thread forming clamping plate 72, and a thread forming cavity 73. One end of the thread forming clamping plate 72 is fixedly connected to a connecting ear 74, and the connecting ear 74 is threadedly connected to the adjusting screw 71. The number of external connecting ears 74 and thread forming clamping plates 72 of a single adjusting screw 71 is two groups. When the adjusting screw 71 rotates, it can synchronously drive multiple thread forming clamping plates 72 to move, so that the mold can inject multiple ink cylinders at a time, thereby improving injection molding efficiency.

[0023] The front and rear sides of the outside of the adjusting screw rod 71 are provided with threads that cooperate with the two sets of connecting ears 74 and rotate counter-rotating to each other, ensuring that when the adjusting screw rod 71 rotates, the two sets of thread forming clamps 72 on the outside of the adjusting screw rod 71 can be driven to move inward or outward at the same time, thereby realizing the injection molding or subsequent demolding of the thread structure of the ink cartridge.

[0024] A center positioning block 8 is fixedly installed at the bottom of the forming movable template 4, and the center positioning block 8 is movably connected to the adjusting screw rods 71 ​​in the two groups of adjusting mechanisms 7. The two groups of adjusting screw rods 71 ​​are restricted by the center positioning block 8 to ensure the stability of the adjusting screw rods 71 ​​during rotation. The adjusting screw rods 71 ​​in the two groups of adjusting mechanisms 7 are fixedly connected.

[0025] By fixedly connecting the adjusting screw rods 71 ​​in the two sets of adjusting mechanisms 7 , the thread forming clamping plates 72 in the two sets of adjusting mechanisms 7 can be controlled synchronously.

[0026] The end of the adjusting screw rod 71 near the driving motor 9 is fixedly connected to the driven synchronous wheel 11, and the external movable sleeve of the driven synchronous wheel 11 is provided with a transmission synchronous belt 12. The driven synchronous wheel 11 and the active synchronous wheel 10 are connected through the transmission synchronous belt 12. The driving motor 9 can drive the two sets of adjusting screw rods 71 ​​to rotate through the active synchronous wheel 10, the driven synchronous wheel 11 and the transmission synchronous belt 12, thereby synchronously adjusting the thread forming clamping plates 72 in the two sets of adjustment mechanisms 7.

[0027] The end of the thread forming clamp 72 away from the connecting ear 74 is fixedly connected to a guide slider 75, and the bottom of the forming movable template 4 is fixedly installed with a guide rail 13, and the guide rail 13 is movably connected to the guide slider 75. When the thread forming clamp 72 moves, the guide slider 75 and the guide rail 13 cooperate with each other to limit it, thereby ensuring the stability of the adjustment mechanism 7 during operation.

[0028] See also Figure 5 An injection port is provided at the top of the movable template base 3, an injection hole that cooperates with the molding cavity 5 is provided at the bottom of the molding movable template 4, and an injection flow channel 14 that is connected to the injection port is provided at the top of the molding movable template 4, ensuring that the molten material can be introduced into the molding cavity 5 along the injection port, the injection flow channel 14 and the injection hole to complete the injection.

[0029] In summary, the ink cartridge injection mold structure of the copier is installed on the injection molding equipment when it is used, and the drive motor 9 is electrically connected to the control system of the injection molding equipment. The injection molding equipment drives the movable plate base 3 and the molding movable plate 4 to move and close the mold, and injects mold into the molding cavity 5 along the injection port, injection flow channel 14 and injection hole on the top of the movable plate base 3. After the ink cartridge is molded, the injection molding equipment drives the movable plate base 3 and the molding movable plate 4 to open the mold. At this time, the adjustment mechanism 7 is in a clamping state. When the movable plate base 3 and the molding movable plate 4 are opened, the ink cartridge can be pulled out along the molding cavity 5. The control system of the injection molding equipment controls the drive motor 9 to drive the active synchronous wheel 10, the transmission synchronous belt 12 and the driven synchronous wheel 11 to rotate, and drives the adjusting screw 71 in the two sets of adjusting mechanisms 7 to rotate, thereby driving the connecting ears 74 and the threaded forming clamping plate 72 in the two sets of adjusting mechanisms 7 to move, releasing the restriction on the thread at the end of the ink cartridge, so that the ink cartridge is disengaged from the adjusting mechanism 7.
