[0023] The beneficial effects of this utility model are:
[0024] This utility model provides a demolding mechanism, including a frame, a platform, an internal thread processing component, and a lifting component. The frame has a receiving cavity along a first direction, within which a mold is placed, and a workpiece is formed at the end of the mold along the first direction. The platform is located within the receiving cavity, and the workpiece is placed on the platform. The platform is movable relative to the mold along the first direction. The internal thread processing component includes a rack, a gear set, and an internal thread insert. The gear set is rotatably mounted on the frame.

[0025] For example, a workpiece is formed at the end of the mold in a first direction, and an internally threaded hole is formed on the workpiece in a second direction by an internally threaded insert. When demolding is required, the lifting assembly is activated, first driving the rack in the first direction, which drives the internally threaded insert to rotate through a gear set, causing the internally threaded insert to move relative to the workpiece in the second direction. The threaded section of the internally threaded insert unscrews from the internally threaded hole of the workpiece. Then, the platform is driven in the first direction, causing the platform to lift the workpiece in the first direction, thereby separating the workpiece from the mold.
[0026] Thus, the lifting assembly can complete the first-stage demolding of the workpiece and the internal thread insert in the second direction, and can also complete the second-stage demolding of the workpiece and the mold in the first direction. The structure is relatively simple and reduces the use of motors. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0044] like Figures 1 to 5 As shown, this utility model provides a demolding mechanism, including a frame 10, a platform 20, an internal thread processing component 30, and a lifting component 40. The frame 10 has a receiving cavity 111 along the first direction X, and a mold is disposed in the receiving cavity 111. The workpiece 1 is formed at the end of the mold in the first direction X. The platform 20 is located in the receiving cavity 111, and the workpiece 1 is placed on the platform 20. The platform 20 can move relative to the mold along the first direction X. The internal thread processing assembly 30 includes a rack 31, a gear set 32, and an internal thread insert 33. The gear set 32 is rotatably mounted on the frame 10. The internal thread insert 33 includes a threaded section 331 and a toothed section 332 along the axial direction. The threaded section 331 is used for threaded connection with the workpiece 1. The rack 31 can drive the internal thread insert 33 to move along the second direction Y through the gear set 32 and the toothed section 332. The lifting assembly 40 can drive the rack 31 and the platform 20 to move relative to the frame 10 along the first direction X. The first direction X is perpendicular to the second direction Y.
[0045] For example, workpiece 1 is formed at the end of the mold in the first direction X, and an internally threaded hole is formed on workpiece 1 in the second direction Y by an internally threaded insert 33. When demolding is required, the lifting assembly 40 is activated, first driving the rack 31 in the first direction X. The rack 31 drives the internally threaded insert 33 to rotate through the gear set 32, so that the internally threaded insert 33 moves relative to workpiece 1 in the second direction Y. The threaded section 331 of the internally threaded insert 33 screws out from the internally threaded hole of workpiece 1. Then, the platform 20 is driven in the first direction X, so that the platform 20 lifts workpiece 1 in the first direction X, so that workpiece 1 is separated from the mold.
[0046] Thus, the lifting assembly 40 can complete the first-stage demolding of the workpiece 1 and the internal thread insert 33 in the second direction Y, and can also complete the second-stage demolding of the workpiece 1 and the mold in the first direction X. The structure is relatively simple and reduces the use of motors.
[0047] For example, the frame 10 is fixed relative to the ground, serving as the mounting base for the entire demolding mechanism. The frame 10 has a receiving cavity 111 along the first direction X.
[0048] Preferably, the first direction X is vertical, so that under the action of gravity, the injection-molded product can be placed relatively stably on the platform 20, and the structural design of the platform 20 for stabilizing the product can be reduced.
[0049] Optionally, the lifting assembly 40 includes a first support plate 41 and a first telescopic member. The first support plate 41 is connected to the frame 10 through the first telescopic member. The first telescopic member can adjust the relative position of the first support plate 41 and the frame 10 in the first direction X. The rack 31 is mounted on the first support plate 41.
[0050] For example, the first telescopic member includes a first fixed part and a first movable part, which are spaced apart in the first direction X. When the first telescopic member extends, the first fixed part and the first movable part move away from each other in the first direction X. When the first telescopic member retracts, the first fixed part and the first movable part move closer to each other in the first direction X. That is, the first fixed part is fixed to the frame 10, the first movable part is fixed to the first support plate 41, and the rack 31 is installed on the side of the first support plate 41 opposite to the first telescopic member. The length direction of the rack 31 is parallel to the first direction X. When it is necessary to remove the internal thread insert 33 from the workpiece 1, the first telescopic member extends and lifts the first support plate 41 in the first direction X, so that the rack 31 moves relative to the frame 10 in the first direction X. The rack 31 is driven by the gear set 32 and the toothed section 332, so that the internal thread insert 33 exits the workpiece 1 in the second direction Y.
[0051] Optionally, the lifting assembly 40 further includes a first guide post 45, the axis of which is parallel to the first direction X. One end of the first guide post 45 is fixed to the frame 10, and a first support plate 41 is sleeved on the first guide post 45 and can slide relative to the first guide post 45. With this configuration, the first guide post 45 can regulate the movement trajectory of the first support plate 41 in the first direction X.
[0052] Optionally, the lifting assembly 40 also includes a second support plate 43 and a second telescopic member. The second support plate 43 is connected to the frame 10 through the second telescopic member. The second telescopic member can adjust the relative position of the second support plate 43 and the frame 10 in the first direction X. The platform 20 is installed on the second support plate 43.
[0053] For example, the second telescopic member includes a second fixed part and a second movable part, which are spaced apart in the first direction X. When the second telescopic member extends, the second fixed part and the second movable part move away from each other in the first direction X. When the second telescopic member retracts, the second fixed part and the second movable part move closer to each other in the first direction X. That is, the second fixed part is mounted on the frame 10, the second movable part is mounted on the second support plate 43, and the platform 20 is mounted on the side of the second support plate 43 opposite to the second telescopic member. When it is necessary to remove the workpiece 1 from the mold, that is, to complete the demolding, the second telescopic member extends, and the platform 20 moves away from the frame 10 along the first direction X. The platform 20 supports the workpiece 1 and removes it from the mold along the first direction X.
[0054] Optionally, the lifting assembly 40 further includes a second guide post, the axis of which is parallel to the first direction X. One end of the second guide post is fixed to the frame 10, and a second support plate 43 is sleeved on the second guide post and can slide relative to it. This configuration allows the second guide post to regulate the movement trajectory of the second support plate 43 in the first direction X.
[0055] Furthermore, the first guide post 45 and the second guide post can be the same guide post, that is, the first support plate 41 and the second support plate 43 are both sleeved on the same guide post. In the first direction X, the second support plate 43 is located on the side of the first support plate 41 facing away from the workpiece 1. In use, the first telescopic component is first activated, causing the first support plate 41 to move away from the second support plate 43 in the first direction X, thus removing the internal thread insert 33 from the workpiece 1. Then, the second telescopic component is activated, causing the second support plate 43 to move closer to the first support plate 41, thereby causing the platform 20 to eject the workpiece 1 from the mold.
[0056] Optionally, the gear set 32 includes a first gear 321 and a second gear 322. The first gear 321 and the second gear 322 are coaxially connected. The radius of the first gear 321 is smaller than the radius of the second gear 322. The rack 31 meshes with the first gear 321 for transmission, and the second gear 322 meshes with the toothed section 332 for transmission.
[0057] With this configuration, since the first gear 321 and the second gear 322 are coaxial, their angular velocities are the same during rotation. Furthermore, because the radius of the first gear 321, acting as the driving gear, is smaller than the radius of the second gear 322, acting as the driven gear, the linear velocity of the second gear 322 is greater than that of the first gear 321. The second gear 322 meshes with the convex tooth section 332 of the internal thread insert 33, and the linear velocity of the internal thread insert 33 is consistent with that of the second gear 322. Thus, when the rack 31 moves the same distance, the internal thread insert 33 can disengage from the workpiece 1 more quickly.
[0058] Optionally, the radius of the toothed segment 332 is smaller than the radius of the second gear 322. Since the linear velocity of the internal thread insert 33 is the same as that of the second gear 322, and the radius of the toothed segment 332 is smaller than that of the second gear 322, that is, the angular velocity of the internal thread insert 33 is greater than that of the second gear 322, and thus, when the second gear 322 rotates for the same number of revolutions, the internal thread insert 33 can rotate for more revolutions, so that the internal thread insert 33 can move a greater distance relative to the frame 10 along the second direction Y, that is, so that the internal thread insert 33 can exit from the workpiece 1 more quickly.
[0059] Optionally, the frame 10 includes a main body 11 and a slider 12. A receiving cavity 111 is opened in the main body 11. The mold is fixed relative to the main body 11. The slider 12 is slidably connected to the main body 11 along the second direction Y. An internal threaded insert 33 is installed on the slider 12.
[0060] For example, the main body 11 is mounted on the ground, and the slider 12 is used to mount the internal thread insert 33, which can slide relative to the main body 11 in the second direction Y. When the rack 31 drives the internal thread insert 33 to rotate, since the internal thread insert 33 is threadedly connected to the workpiece 1, the workpiece 1 applies a force to the internal thread insert 33 in the second direction Y. The internal thread insert 33 acts on the slider 12, causing the slider 12 to slide relative to the main body 11 in the second direction Y, thereby causing the internal thread insert 33 to exit the workpiece 1.
[0061] Optionally, the frame 10 also includes a guide support 13, which is fixed to the main body 11. An internally threaded insert 33 is inserted into the guide support 13 and can move relative to the guide support 13 along the second direction Y.
[0062] For example, the slider 12 is located on the side of the guide support 13 facing away from the workpiece 1. The guide support 13 supports the internal thread insert 33, reducing the suspended portion of the internal thread insert 33, which can maintain the stability of the internal thread insert 33 relative to the workpiece 1 and regulate the movement path of the internal thread insert 33 along the second direction Y.
[0063] Optionally, the frame 10 forms multiple workstations in the second direction Y and / or the third direction Z, each workstation having a corresponding receiving cavity 111 and a corresponding platform 20 and internal thread processing assembly 30; the first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0064] With this configuration, the demolding mechanism can demold multiple workpieces 1.
[0065] Optionally, the racks 31 of each platform 20 and each set of internal thread machining components 30 are driven by the same lifting component 40.
[0066] This setup reduces the number of lifting components 40 required and unifies the actions of multiple workstations.
[0067] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
