Description

Technical Field

[0001] This utility model relates to the field of mold demolding technology, specifically to an injection mold that facilitates quick demolding. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, and a wide variety of colors and patterns.

[0003] For example, a Chinese patent (publication number: CN221985707U) discloses an injection mold that facilitates demolding. The mold includes: a base, a lower mold box connected to the top of the base, a lower mold penetrating through the interior of the box, a first protrusion fixedly connected to the left side of the lower mold, an ejector pin connected to the base, hydraulic rods connected to both sides of the top of the base, an upper mold connected between the two hydraulic rods, an injection port connected to the top of the upper mold, and water coolers connected to both sides of the lower mold box. This injection mold facilitates demolding by preventing waste from falling into the box during subsequent cleaning of the injection port, thus preventing contamination of the box. Simultaneously, the added ejector pin and water cooler cool and discharge the finished workpiece, facilitating demolding during use and preventing the workpiece from adhering to the outside of the lower mold, thereby increasing the demolding speed.

[0004] This patent uses ejector pins to eject the workpiece, but directly squeezing the freshly injection-molded workpiece may cause mold deformation and poor performance. Therefore, an injection mold that facilitates quick demolding is proposed to solve the above-mentioned problems. Utility Model Content

[0030] 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.

[0031] Please see Figure 1 In this embodiment, an injection mold for quick demolding includes a support column 1, a housing 2 fixed to the top of the support column 1, a sealing shell 3 slidably connected to the outer side of the housing 2, a handle fixed to the top of the sealing shell 3, a limiting component 4 on the left side of the housing 2, and two connecting plates 5 that penetrate to the top of the sealing shell 3 fixed to the inner bottom wall of the housing 2.

[0032] Understandably, the use of handles of the same specifications facilitates the pulling of the sealing shell 3, thereby improving the ease of use of the mold.

[0033] A mold shell 6 is slidably connected between two connecting plates 5. A movable door is hinged to the front of the mold shell 6. A lifting mechanism fixed to the mold shell 6 is provided on the support column 1. A condenser pipe 13 is fixed inside the outer peripheral wall of the outer shell 2. A feed pipe 14 extending into the inner cavity of the mold shell 6 is fixed to the top of the sealing shell 3. A cover plate 16 slidably connected to the feed pipe 14 is fixed to the inner cavity wall of the top of the sealing shell 3. Two top support components 15 are provided on the cover plate 16.

[0034] The lifting mechanism enables the workpiece to be lifted, which facilitates the rapid demolding of the mold. The condenser pipe 13 facilitates the cooling of the mold, thus enabling the rapid cooling of the mold and facilitating the demolding process.

[0035] The lifting mechanism includes a servo motor 7, a drive gear 8, a driven gear 9, a threaded rod 10, a sliding sleeve 11, and a top support rod 12. The servo motor 7 is fixed to the outside of the support column 1, the drive gear 8 is fixed to the output shaft of the servo motor 7, and the driven gear 9 meshes with the top of the drive gear 8.

[0036] It is also understandable that the meshing setting facilitates the power supply of the servo motor 7 to drive the driven gear 9 to rotate, thereby facilitating the rotation of the threaded rod 10, promoting the stable operation of the overall mechanism, and enabling the demolding function.

[0037] The threaded rod 10 is fixed at the axis of the driven gear 9. The top of the threaded rod 10 is rotatably connected to the bottom of the outer shell 2. The sliding sleeve 11 is threadedly connected to the outer side of the threaded rod 10. The top support rod 12 is fixed to the left side of the sliding sleeve 11. The top support rod 12 passes through the inner cavity of the outer shell 2. The top of the top support rod 12 is fixed to the bottom of the mold shell 6.

[0038] It should be noted that by rotating the threaded rod 10, the lifting and lowering of the top support rod 12 is achieved through the threaded connection and the sliding connection between the mold shell 6 and the connecting plate 5, which is beneficial for the lifting and lowering of the mold shell 6 and facilitates the rapid demolding of the mold.

[0039] Please see Figure 2 To improve the stability of the mold, the limiting component 4 in this embodiment includes a fixing block 401, a connecting block 402, a rotating plate 403, a handle 404, a rotating frame 405, a movable column 406, a baffle 407, a top support spring 408, and a locking block 409. The fixing block 401 is fixed to the left side of the sealing shell 3, the connecting block 402 is fixed to the left side of the outer shell 2, the rotating plate 403 is rotatably connected to the inner side of the connecting block 402, and a rotating column is rotatably connected to the inner side of the connecting block 402.

[0040] The rotating column facilitates the rotatable connection between the connecting block 402 and the rotating plate 403, which is beneficial to the stable operation of the overall component. This also helps to control the connection between the outer shell 2 and the sealing shell 3, thereby improving the overall stability of use.

[0041] The rotating plate 403 is fixed to the rotating column, and the rotating plate 403 is hinged to the connecting block 402 through the rotating column. The handle 404 is fixed to the bottom of the rotating plate 403. The rotating frame 405 is hinged to the front and rear sides of the rotating plate 403. The movable column 406 is slidably connected to the top of the rotating frame 405. The baffle 407 is fixed to the bottom of the movable column 406.

[0042] It can be seen that the baffle 407 helps to limit the top support spring 408, which is beneficial to the stable operation of the overall component and thus improves the stability of the mold.

[0043] The top support spring 408 is fixed between the top of the baffle 407 and the inner wall of the top of the rotating frame 405. The top support spring 408 is wrapped around the outside of the movable column 406. The locking block 409 is fixed to the top of the movable column 406 and is engaged with the fixed block 401.

[0044] In this embodiment, the top support spring 408 provides tension to the locking block 409, which in turn facilitates the self-locking of the rotating plate 403 in the vertical state through the hinged setting. This improves the ease of use of the component and enhances the overall mold performance.

[0045] Please see Figure 3 In order to ensure the stable use of the mold, the connecting plate 5 in this embodiment includes a connecting seat 501, a hinge column 502 and a top support block 503. The connecting seat 501 is fixed to the inner bottom wall of the outer shell 2 and is slidably connected to the top of the sealing shell 3. Sliding channels are provided on the opposite side of the two connecting seats 501.

[0046] It should be noted that the sliding channel facilitates the sliding connection between the connecting seat 501 and the mold shell 6, thereby providing a limiting structure for the lifting mechanism, enabling the lifting function of the mold shell 6, ensuring the stable use of the overall mold function, and improving the overall performance.

[0047] Sliding blocks are fixed on both the left and right sides of the mold shell 6. The mold shell 6 is slidably connected to the sliding channel through the sliding blocks. The hinge column 502 is rotatably connected to the inner side of the connecting seat 501. Placement openings are opened on the opposite side of the two connecting seats 501. The hinge column 502 is located in the placement opening. The top support block 503 is fixed to the outer side of the hinge column 502.

[0048] In this embodiment, the placement opening facilitates the concealment of the top support block 503, thereby enabling the sealing shell 3 to be positioned and reset, promoting stable use of the overall mold, and improving the overall performance.

[0049] Please see Figure 4 In order to ensure the stable use of the mold, the top support assembly 15 in this embodiment includes a fixed shell 1501, an elastic spring 1502 and a top support plate 1503. The fixed shell 1501 is fixed to the top of the cover plate 16, and the top support plate 1503 is slidably connected to the inner side of the fixed shell 1501. Sliding openings are provided on the opposite sides of the two fixed shells 1501.

[0050] The sliding port design facilitates the stable sliding of the top support plate 1503, which in turn promotes the stable use of the overall component and improves the overall mold's stability, thereby enhancing the mold's performance.

[0051] The top support plate 1503 is slidably connected to the fixed shell 1501 through a sliding port, and the elastic spring 1502 is fixed between the top support plate 1503 and the fixed shell 1501. The elastic spring 1502 is located in the inner cavity of the fixed shell 1501.

[0052] In this embodiment, the elastic spring 1502 facilitates the support of the top support plate 1503, thereby facilitating the compression of the top support block 503 and the retraction of the top support block 503, which in turn facilitates the reset of the sealing shell 3. This enables the sealing shell 3 to be opened and closed conveniently, thus improving the overall ease of use of the mold.

[0053] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0054] The working principle of the above embodiments is as follows:

[0055] Molding is injected into the mold shell 6 through the feed pipe 14. After the mold is formed, the handle 404 is lifted, which drives the rotating plate 403 to adjust its angle, thereby causing the rotating frame 405 to move upward. Then, through the hinge action of the connecting block 402 and the rotating plate 403, the locking block 409 is removed from the fixing block 401, thereby unlocking the outer shell 2 and the sealing shell 3. Then, the handle is pulled upward to lift the sealing shell 3 upward, so that the top support block 503 is hidden when the sealing shell 3 moves upward due to the rotation action of the top support block 503. When the top support block 503 is located between the cover plate 16 and the top wall of the sealing shell 3, the top support block 503 is hidden by the weight. The force will cause it to flip out, thus suspending the top of the top support block 503 over the sealing shell 3. If it is necessary to lower the sealing shell 3, the sealing shell 3 can be pulled upwards again. The supporting action of the elastic spring 1502 will drive the top support plate 1503 to support the top support block 503, thereby causing the top support block 503 to retract. Then the sealing shell 3 will be lowered. After the sealing shell 3 is opened, the servo motor 7 will be started. The mold shell 6 will be raised through the thread action and the sliding action between the mold shell 6 and the outer shell 2. Then it will be opened through the hinged door set on the front of the mold shell 6, thereby realizing the quick demolding of the mold. The whole is convenient and stable to use, and the use effect is good.
