[0002] An injection mold is a tool specifically used for plastic injection molding. It consists of a movable mold and a fixed mold. By closing the mold, the plastic material fills the mold cavity under high pressure to form the desired product shape.
[0003] At present, in the field of molds, for some injection molded shell products, undercuts need to be designed according to the structural connection requirements of the overall product. In order to smoothly demould the product, a special internal mold design is required to achieve smooth demoulding. The inclined ejector core pulling mechanism is a common mechanism used to solve the demoulding of the undercut structure, but some problems may be encountered in practical applications. The existing inclined ejector mechanism is usually composed of multiple moving parts, including an inclined ejector column, a guide sleeve, an inclined ejector plate, etc. These parts need to coordinate movement to achieve the action of the inclined ejector.
[0004] However, the space of the injection mold is usually limited, which brings challenges to the design of the tilting mechanism. It is a complex and critical task to design the structure of the tilting mechanism to meet the requirements of demoulding and resetting. Designers need to fully consider factors such as space limitations, motion control and resetting mechanisms to ensure that the tilting mechanism can perform complex tasks in a limited space and ensure the normal operation of the injection mold. Therefore, it is urgent to develop a tilting mechanism with a simple and reasonable structure that can smoothly achieve release and resetting. Utility Model Content

[0006] The present application provides a tilting mechanism and an injection mold using the following technical solutions:
[0007] A tilted ejector mechanism is used for separating a mold from a product and its undercut structure, comprising a tilted ejector rod and a slider, wherein the tilted ejector rod and the slider are slidably connected via a mortise and tenon structure; the tilted ejector rod is driven to eject, thereby driving the slider and the product to be ejected together, and after ejection, the tilted ejector rod continues to move and withdraws from the undercut structure of the product; the mechanism also comprises a pin member, which is used to control the movement stroke between the tilted ejector rod and the slider during tripping and resetting operations, and the pin member comprises a pin provided on the slider and a limiting groove provided on the tilted ejector rod, wherein the limiting groove passes through the tilted ejector rod, the pin is horizontally arranged, the pin passes through the slider and is inserted into the limiting groove, and the pin slides and abuts in the limiting groove.
[0008] By adopting the above technical scheme, the inclined ejector mechanism of the present application is composed of a small number of parts and components, which is easy to manufacture and install, and the overall structural design is simple and reasonable.

After the product is completely ejected, the inclined ejector rod continues to move and withdraws from the undercut structure of the product to complete the separation process; in this process, on the one hand, the mortise and tenon structure connects the inclined ejector rod The pin member and the mortise and tenon mechanism are designed to control the movement stroke and movement trajectory of the lift rod relative to the slider, ensuring the accuracy of the demoulding work of the lift rod and the slider, and enabling the lift rod and the slider to automatically reset after the separation is completed, preparing for the next round of operation, thereby improving production efficiency.
[0009] In a specific possible implementation mode, the mortise and tenon structure includes a guide block provided on the sliding block and a guide groove provided on the inclined ejector rod, and the guide block is inserted into the guide groove and slides against the guide groove.
[0010] By adopting the above technical solution, when the tilting lift mechanism starts to work, the guide block on the slider will slide in the guide groove on the tilting lift rod to ensure that the movement of the tilting lift rod is accurately restricted and guided. The mortise and tenon structure is simply designed and can ensure accurate alignment and stable movement between the tilting lift rod and the slider, thereby ensuring stable operation and precise operation of the tilting lift mechanism.
[0011] In a specific possible implementation scheme, the pin is arranged on the guide block, the guide groove is communicated with the limiting groove, and the pin passes through the guide block and is inserted into the limiting groove.

[0017] In a specific possible implementation scheme, it further includes a reset structure, which is arranged on the slider, and the mold is provided with a reset groove that is plugged into and matched with the reset structure.
[0018] By adopting the above technical solution, when the tilting lift mechanism needs to be reset, a reliable connection is formed between the reset structure and the reset groove on the mold, thereby ensuring that the slider and the tilting lift rod return to the predetermined position, and the position of the tilting lift mechanism can be effectively controlled and adjusted so that it can be accurately aligned with the mold and prepare for the next operation, thereby ensuring the accurate reset of the tilting lift mechanism and the mold, thereby ensuring the normal operation and stability of the equipment.
[0019] In a specific possible implementation manner, the reset structure is provided with a first inclined surface, the reset groove is provided with a second inclined surface, and the first inclined surface and the second inclined surface are slidably opposed to each other.
[0020] By adopting the above technical solution and utilizing the sliding resistance design between the first inclined surface and the second inclined surface, not only can resistance be provided for the reset structure of the slider and the reset groove of the mold to maintain a firm connection, but the slider and the inclined ejector rod can also be guided to move along a predetermined path to ensure that they correctly return to the target position on the mold, thereby enhancing the stability and controllability of the reset process, thereby ensuring the normal operation and production efficiency of the equipment.
[0021] In a specific possible implementation scheme, the surfaces of the sliding block and the inclined lift rod close to the mortise and tenon structure are respectively configured as a third inclined plane and a fourth inclined plane, and the third inclined plane and the fourth inclined plane slide against each other.
[0022] By adopting the above technical solution, the sliding friction between the third inclined surface and the fourth inclined surface can be used to guide the slider and the inclined ejector rod to move along a predetermined path, so that they move along the correct trajectory during the resetting process, and provide additional resistance to ensure that they maintain close contact during the movement, thereby improving the accuracy and reliability of the system; and this design can also reduce the complexity of the space design, effectively utilize the space of the mold, and reduce the number of additional parts or complex structures required, thereby simplifying the overall design and improving manufacturing efficiency.
[0023] An injection mold comprises the tilting ejector mechanism as described above.
[0024] By adopting the above technical scheme, the injection mold of the present application realizes efficient demoulding operation and stable resetting through the optimized tilting lift mechanism design; after the injection molding is completed, the injection mold opens and performs the release work through the tilting lift mechanism, and the mortise and tenon structure sliding connection of the tilting lift rod and the slider ensures smooth movement, thereby quickly ejecting the product from the mold and improving production efficiency; the design of the pin member limits the movement range of the tilting lift rod and the slider and ensures their stable resetting. After each production cycle, the mold can be ready for the next injection molding, saving production time and improving production efficiency; the design of the tilting lift mechanism ensures the accurate alignment and stability of the injection mold, reduces the production cycle time, and reduces production costs.

DETAILED DESCRIPTION
[0039] The following is combined with Figure 1-7 This application is described in further detail.
[0040] Reference Figure 1 and Figure 2, the embodiment of the present application discloses a tilting mechanism, which is used for separating a mold from a product 3 and its undercut structure 31. The tilting mechanism 1 includes a tilting rod 4 and a slider 5. The tilting rod 4 and the slider 5 are slidably connected through a mortise and tenon structure 6. In the present embodiment, the tilting rod 4 and the slider 5 have a shape structure consistent with the appearance of the product 3. The tilting rod 4 has a groove or a convex portion corresponding to the undercut structure 31 of the product 3. In the present embodiment, the tilting rod 4 is provided with a groove corresponding to the undercut structure 31 of the product 3.
[0041] The inclined ejector rod 4 is driven to move obliquely upward, driving the slider 5 and the product 3 to move obliquely upward together; after the inclined ejector rod 4 and the slider 5 are moved out of the mold, the inclined ejector rod 4 is driven to continue to move, at which time the inclined ejector rod 4 moves relatively to the side of the undercut structure 31 away from the product 3, and exits from the undercut structure 31 of the product 3;
[0042] The surfaces of the slider 5 and the lift rod 4 on the side close to the mortise and tenon structure 6 are respectively set as the third inclined surface 51 and the fourth inclined surface 41. In this embodiment, the moving direction of the slider 5 is parallel to the inclination direction of the third inclined surface 51 and the fourth inclined surface 41, and the third inclined surface 51 and the fourth inclined surface 41 slide and conflict with each other. In this embodiment, the inclination direction of the third inclined surface 51 and the fourth inclined surface 41 and the moving direction of the lift rod 4 include but are not limited to an angle of 30°-80°; thereby, the slider 5 and the lift rod 4 can be guided to move along a predetermined path, so that they move along the correct trajectory during the resetting process, and provide additional resistance to ensure that they maintain close contact during the movement, thereby improving the accuracy and reliability of the system; and this design can also reduce the complexity of the space design, effectively utilize the space of the mold, and reduce the number of required additional parts or complex structures, thereby simplifying the overall design and improving manufacturing efficiency;
[0043] The tilting mechanism 1 also includes a pin member 7, which is used to limit the movement stroke of the tilting rod 4 relative to the slider 5 after ejection. In this embodiment, when the tilting rod 4 moves relatively to the side of the undercut structure 31 away from the product 3, the pin member 7 will limit the movement stroke of the tilting rod 4 relative to the slider 5, thereby preventing the tilting rod 4 from separating from the slider 5; the pin member 7 is also used for resetting the tilting rod 4 and the slider 5. After the tilting rod 4 and the slider 5 are separated, the tilting rod 4 is driven to move obliquely backward and reset. At this time, the pin member 7 can control the movement stroke of the tilting rod 4 relative to the slider 5, so that the tilting rod 4 and the slider 5 are automatically reset to the initial position, completing the reset work of the tilting mechanism 1 itself;
[0044] When the inclined ejector mechanism 1 is working, in the initial state, the inclined ejector rod 4 and the slider 5 are connected by the mortise and tenon structure 6 and are in a stationary state; when the inclined ejector rod 4 is driven to move obliquely upward to eject, the inclined ejector rod 4 will drive the slider 5 and the product 3 to eject together, and the mold and the product 3 will be separated. After the inclined ejector rod 4 and the slider 5 are moved out of the mold, the inclined ejector rod 4 continues to move. At this time, the inclined ejector rod 4 will move relatively to the side of the undercut structure 31 away from the product 3, and withdraw from the undercut structure 31 of the product 3, completing the separation process;
[0045] During the operation of the inclined ejector mechanism 1, on the one hand, the mortise and tenon structure 6 connects the inclined ejector rod 4 and the slider 5, ensuring stability and reliability during the operation and reducing the failure rate; on the other hand, the pin member 7 limits the movement of the inclined ejector rod 4 relative to the slider 5 to prevent it from detaching from the slider 5, ensuring that the inclined ejector rod 4 will not detach from the slider 5 and lose control after ejecting the slider 5 and separating the product 3, thereby maintaining control and stability; and the coordinated design of the pin member 7 and the mortise and tenon mechanism can control the movement of the inclined ejector rod 4 relative to the slider 5 and the movement trajectory, ensuring the accuracy of the demoulding work of the inclined ejector rod 4 and the slider 5, and enabling the inclined ejector rod 4 and the slider 5 to automatically reset after the separation is completed, ready for the next round of operation, thereby improving production efficiency.
[0046] Reference Figure 2 and Figure 3 The mortise and tenon structure 6 includes a guide block 61 provided on the slider 5 and a guide groove 62 provided on the inclined ejector rod 4. In this embodiment, the guide groove 62 is provided along the moving direction of the slider 5. The guide block 61 is inserted into the guide groove 62 and slides against the guide groove 62. The moving direction of the guide block 61 is parallel to the moving direction of the slider 5.
[0047] The length of the guide groove 62 is greater than the length of the guide block 61; thus, the length of the guide groove 62 can fully accommodate the guide block 61 and provide sufficient space to ensure stable sliding and movement. The longer guide groove 62 makes the installation and maintenance process more convenient, and the guide block 61 can more easily enter and exit the guide groove 62 without the need for overly precise alignment; and the longer guide groove 62 can provide more support area, so that the guide block 61 is more stable when sliding therein;
[0048] When the tilting lift mechanism 1 starts to work, the guide block 61 on the slider 5 will slide in the guide groove 62 on the tilting lift rod 4 to ensure that the movement of the tilting lift rod 4 is accurately restricted and guided. The mortise and tenon structure 6 is simply designed to ensure accurate alignment and stable movement between the tilting lift rod 4 and the slider 5, thereby ensuring the stable operation and precise operation of the tilting lift mechanism 1.
[0049] Reference Figure 4 and Figure 5The pin member 7 includes a pin 71 provided on the guide block 61 and a limiting groove 72 provided on the inclined ejector rod 4. The limiting groove 72 passes through the inclined ejector rod 4 and is connected to the guide groove 62. In this embodiment, the setting direction of the limiting groove 72 is the same as the setting direction of the guide groove 62. The pin 71 is horizontally arranged, the pin 71 passes through the guide block 61 and is inserted into the limiting groove 72. The pin 71 slides and contacts in the limiting groove 72. The moving direction of the pin 71 is parallel to the moving directions of the slider 5 and the guide block 61.
[0050] The design that the pin 71 is located on the guide block 61 and the guide groove 62 is connected to the limit groove 72 can facilitate the design and manufacturing process of the tilting mechanism 1. The compact layout simplifies the manufacturing and installation process of the tilting mechanism 1, and at the same time makes the overall structure of the tilting mechanism 1 more compact, saves space, and realizes a more efficient design and function of the tilting mechanism 1.
[0051] The inner wall surface of the limiting groove 72 in contact with the pin 71 is provided with an arc surface 721; the arc surface 721 can provide a smoother sliding and contact process for the pin 71, reduce the sharp edges on the contact surface, reduce the friction, thereby extending the service life of the parts and improving the stability of the operation, and enhancing the durability and performance of the tilting mechanism 1;
[0052] When the locking cam 72 is in the closed position, the locking cam 73 is in the closed position, and the locking cam 73 is in the closed position, so that the locking cam 73 is in the open position and the locking cam 73 is in the closed position.
[0053] Reference Figure 6 The tilting mechanism 1 further includes a reset structure 8, which is disposed on the slider 5, and the mold is provided with a reset groove 21 which is plugged and matched with the reset structure 8;
[0054] The reset structure 8 is provided with a first inclined surface 81, and the reset groove 21 is provided with a second inclined surface 211, and the first inclined surface 81 and the second inclined surface 211 slide against each other; the first inclined surface 81 and the second inclined surface 211 provide resistance for the reset structure 8 of the slider 5 and the reset groove 21 of the mold to maintain a firm connection; when the lift mechanism 1 is reset to the initial position on the mold, the first inclined surface 81 and the second inclined surface 211 can guide the slider 5 and the lift rod 4 to move along a predetermined path, ensuring that they correctly return to the target position on the mold, enhancing the stability and controllability of the reset process, thereby ensuring the normal operation and production efficiency of the equipment;
[0055] When it is necessary to reset the tilting lift mechanism 1, the tilting lift rod 4 is driven to reset and move obliquely to the rear. At this time, the limit groove 72 on the tilting lift rod 4 slides relatively along the pin 71, so that the slider 5 and the tilting lift rod 4 return to the initial position; continue to drive the tilting lift rod 4 to move obliquely to the rear, driving the slider 5 to move together. When the reset structure 8 on the slider 5 encounters the reset groove 21 on the mold, the first inclined surface 81 and the second inclined surface 211 guide the slider 5 and the tilting lift rod 4 to move along a predetermined path, thereby ensuring that the slider 5 and the tilting lift rod 4 return to the predetermined position on the mold, so as to effectively control and adjust the position of the tilting lift mechanism 1 so that it can be accurately aligned with the mold and prepare for the next operation, thereby ensuring the accurate reset of the tilting lift mechanism 1 and the mold, thereby ensuring the normal operation and stability of the equipment.
[0056] The present application also provides an injection mold, comprising the tilting lift mechanism 1 as described above;
[0057] Reference Figure 6 and Figure 7 The injection mold further includes a mold core 2, and the inclined ejector mechanism 1 is disposed in the mold core 2 and slidably disposed in the mold core 2. In this embodiment, a reset groove 21 is disposed on the inner wall of the mold core 2 of the injection mold and is used in conjunction with the reset structure 8 of the slider 5;
[0058] A gap 9 is left between the inclined ejector rod 4 and the mold core 2. In this embodiment, the inner wall of the mold core 2 is provided with a chamfered structure, so as to form a gap 9 between the inclined ejector rod 4 and the mold core 2. Through the setting of the gap 9, the existence of the gap 9 makes it easier to install the inclined ejector mechanism 1 inside the mold core 2, and it is also easier to operate when maintenance or replacement is required; and it can also ensure that the inclined ejector mechanism 1 will not interfere with the mold core 2 when sliding, thereby ensuring the normal operation of the injection mold, avoiding possible damage or failure, and improving the stability and life of the injection mold.
[0059] After the injection molding is completed, the injection mold is opened and the release work is performed through the tilting ejector mechanism 1. The sliding connection between the mortise and tenon structure 6 of the tilting ejector rod 4 and the slider 5 ensures smooth movement, thereby quickly ejecting the product 3 from the mold and improving production efficiency; the design of the pin member 7 limits the movement range of the tilting ejector rod 4 and the slider 5 and ensures their stable reset. After each production cycle, the mold can be ready for the next injection molding, saving production time and improving production efficiency; the design of the tilting ejector mechanism 1 ensures the accurate alignment and stability of the injection mold, reduces the production cycle time, and reduces production costs.
[0060] The implementation principle of the embodiment of the present application is as follows: the inclined ejection mechanism 1 of the present application is composed of a small number of parts and components, which is easy to manufacture and install, and the overall structural design is simple and reasonable. The mortise and tenon structure 6, the pin member 7 and the reset structure 8 designed on the slider 5 and the inclined ejection rod 4 can effectively realize the release and reset of the mechanism;
[0061] When the inclined ejector mechanism 1 is working, in the initial state, the inclined ejector rod 4 and the slider 5 are connected by the mortise and tenon structure 6 and are in a stationary state. At this time, the pin 71 is relatively located at the top of the limiting groove 72; when the injection mold is opened, the inclined ejector rod 4 is driven to move obliquely upward to eject, and the inclined ejector rod 4 will drive the slider 5 and the product 3 to eject together, and the mold and the product 3 will be separated. After the inclined ejector rod 4 and the slider 5 move out of the mold core 2 of the injection mold, the inclined ejector rod 4 continues to move. At this time, the inclined ejector rod 4 will move relatively to the side of the undercut structure 31 away from the product 3. During this process, the guide block 61 on the slider 5 will slide in the guide groove 62 on the inclined ejector rod 4 to ensure that the movement of the inclined ejector rod 4 is accurately restricted and guided, and the limiting groove 72 on the inclined ejector rod 4 slides relative to the pin 71. When the pin 71 slides relatively to the bottom of the limiting groove 72, the inclined ejector rod 4 stops moving and completely withdraws from the undercut structure 31 of the product 3 to complete the separation process.
[0062] When resetting is required, the inclined ejector rod 4 is driven to reset and move obliquely to the rear. At this time, the limit groove 72 on the inclined ejector rod 4 slides relatively along the pin 71, and the pin 71 returns to the top of the limit groove 72, thereby realizing the reset control between the inclined ejector rod 4 and the slider 5; continue to drive the inclined ejector rod 4 to move obliquely to the rear, driving the slider 5 to move together. When the reset structure 8 on the slider 5 encounters the reset groove 21 on the mold core 2 in the injection mold, the first inclined surface 81 and the second inclined surface 211 guide the slider 5 and the inclined ejector rod 4 to move along a predetermined path, thereby ensuring that the slider 5 and the inclined ejector rod 4 return to the predetermined position on the mold core 2 of the injection mold, thereby effectively controlling and adjusting the position of the inclined ejector mechanism 1 so that it can be accurately reset to the mold core 2 to prepare for the next operation, thereby ensuring the accurate reset of the inclined ejector mechanism 1 and the injection mold, thereby ensuring the normal operation and stability of the overall equipment.
[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
