Technical Field

[0001] The present application relates to the field of injection mold technology, and in particular to a tilting ejector mechanism and an injection mold. Background Art

[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 screw component, which is used to control the movement stroke between the tilted ejector rod and the slider during release and reset operations, wherein the screw component comprises a screw disposed on the slider, the tilted ejector rod is provided with a limiting groove, the screw is vertically disposed, the screw first passes through the slider and is threadedly connected to the slider and then is inserted into the limiting groove, and the screw slides 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 are easy to manufacture and install, and the overall structural design is simple and reasonable. The design of the mortise and tenon structure and the screw parts can effectively realize the disengagement and resetting of the mechanism; in the initial state, the inclined ejector rod and the slider are connected by the mortise and tenon structure and are in a stationary state; when the inclined ejector rod is driven to eject, it will drive the slider and the product to eject together, separating the mold and the product. 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, the coordinated design of the screw parts and the mortise and tenon structure can control the moving stroke and moving trajectory of the inclined ejector rod relative to the slider, ensure the accuracy of the demoulding work of the inclined ejector rod and the slider, and enable the inclined ejector rod and the slider to automatically reset after the separation is completed, ready for the next round of operation, thereby improving production efficiency; and the screw parts are easy and quick to install, and the position of the screws can be adjusted to change the working stroke of the inclined ejector mechanism to adapt to products and molds of different sizes and shapes, thereby improving the applicability and versatility of the inclined ejector mechanism.

[0014] By adopting the above technical solution, a blocking block is designed to be used in the mounting hole and cooperates with the screw to seal the screw in the mounting hole; such a design can ensure that the position of the screw in the mounting hole is fixed, prevent it from accidentally moving or loosening during operation, and ensure the stability and reliability of the tilting mechanism.

[0015] In a specific possible implementation manner, the top surface of the blocking block is flush with the top surface of the sliding block.

[0017] In a specific possible implementation manner, a movable space is left between the screw and the bottom of the limiting groove.

[0018] By adopting the above technical solution, the movable space reduces the friction between the screw and the limit groove, and reduces the wear on the inner wall of the limit groove of the inclined ejector rod during the movement of the screw, thereby extending the service life of the inclined ejector mechanism and improving its stability and reliability.

[0019] In a specific possible implementation manner, a reset groove is provided on the slider, and a reset convex portion is provided on the mold, and the reset groove is plug-fitted with the reset convex portion.

[0020] By adopting the above technical scheme, when the tilting lift mechanism needs to be reset, the reset protrusion cooperates with the reset groove so that the reset groove on the slider cooperates with the reset protrusion 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 to 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.

[0021] In a specific possible implementation manner, the reset groove is provided with a guiding inclined surface, and the reset protrusion is provided with a matching inclined surface, the guiding inclined surface guides the reset protrusion to enter the reset groove, and the guiding inclined surface and the matching inclined surface slide and conflict with each other.

[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 is opened and the release work is performed 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 screw part 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.

[0025] In a specific possible implementation manner, the injection mold includes a mold core, the lift mechanism is disposed in the mold core and is slidably disposed in the mold core, and a gap is left between the lift rod and the mold core.

[0026] By adopting the above technical solution and setting the gap, the existence of the gap makes it easier to install the inclined lift mechanism inside the mold core and to operate it more easily when maintenance or replacement is required; and it can also ensure that the inclined lift mechanism will not interfere with the mold core 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.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] 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 2 and its undercut structure 21. The tilting mechanism 1 includes a tilting rod 3 and a slider 4, and the tilting rod 3 and the slider 4 are slidably connected by a mortise and tenon structure 5; in this embodiment, the tilting rod 3 and the slider 4 have a shape structure consistent with the appearance of the product 2, and the tilting rod 3 has a groove or a convex portion corresponding to the undercut structure 21 of the product 2. In this embodiment, the tilting rod 3 is provided with a groove corresponding to the undercut structure 21 of the product 2;

[0042] The inclined ejector rod 3 is driven to move obliquely upward, driving the slider 4 and the product 2 to move obliquely upward together; after the inclined ejector rod 3 and the slider 4 are moved out of the mold, the inclined ejector rod 3 is driven to continue to move, at which time the inclined ejector rod 3 moves relatively to the side of the undercut structure 21 away from the product 2, and exits from the undercut structure 21 of the product 2;

[0043] The surfaces of the slider 4 and the lift rod 3 on the side close to the mortise and tenon structure 5 are respectively set as the first inclined surface 43 and the second inclined surface 31, and the first inclined surface 43 and the second inclined surface 31 slide and conflict with each other. In this embodiment, the moving direction of the slider 4 is parallel to the inclination direction of the first inclined surface 43 and the second inclined surface 31. In this embodiment, the inclination direction of the first inclined surface 43 and the second inclined surface 31 and the moving direction of the lift rod 3 include but are not limited to an angle of 30°-80°; thereby, the slider 4 and the lift rod 3 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;

[0044] The inclined ejection mechanism 1 further includes a screw member 6, which is used to limit the movement stroke of the inclined ejection rod 3 relative to the slider 4 after ejection. In the present embodiment, when the inclined ejection rod 3 moves relatively to the side of the undercut structure 21 away from the product 2, the screw member 6 will limit the movement stroke of the inclined ejection rod 3 relative to the slider 4, thereby preventing the inclined ejection rod 3 from separating from the slider 4; the screw member 6 is also used for resetting the inclined ejection rod 3 and the slider 4. After the separation of the inclined ejection rod 3 and the slider 4 is completed, the inclined ejection rod 3 is driven to move obliquely backward and reset. At this time, the screw member 6 can control the movement stroke of the inclined ejection rod 3 relative to the slider 4, so that the inclined ejection rod 3 and the slider 4 are automatically reset to the initial position, completing the reset work of the inclined ejection mechanism 1 itself;

[0045] When the inclined ejector mechanism 1 is working, in the initial state, the inclined ejector rod 3 and the slider 4 are connected by the mortise and tenon structure 5 and are in a stationary state; when the inclined ejector rod 3 is driven to move obliquely upward to eject, the inclined ejector rod 3 will drive the slider 4 and the product 2 to eject together, and the mold and the product 2 will be separated. After the inclined ejector rod 3 and the slider 4 are moved out of the mold, the inclined ejector rod 3 continues to move. At this time, the inclined ejector rod 3 will move relatively to the side of the undercut structure 21 away from the product 2, and withdraw from the undercut structure 21 of the product 2, completing the separation process;

[0046] During the operation of the inclined ejector mechanism 1, the screw component 6 limits the moving stroke of the inclined ejector rod 3 relative to the slider 4 to prevent it from detaching from the slider 4, ensuring that the inclined ejector rod 3 will not detach from the slider 4 and lose control after ejecting the slider 4 and separating the product 2, thereby maintaining control and stability; and the coordinated design of the screw component 6 and the mortise and tenon structure 5 can control the moving stroke and moving trajectory of the inclined ejector rod 3 relative to the slider 4, ensuring the accuracy of the demoulding work of the inclined ejector rod 3 and the slider 4, and allowing the inclined ejector rod 3 and the slider 4 to automatically reset after the separation is completed, ready for the next round of operation, thereby improving production efficiency.

[0047] Reference Figure 3 and Figure 4 The mortise and tenon structure 5 includes a dovetail block 51 provided on the inclined ejector rod 3 and a dovetail groove 52 provided on the slider 4. In the present embodiment, the dovetail groove 52 is provided along the moving direction of the slider 4, and the dovetail block 51 is inserted into the dovetail groove 52 and slides against the dovetail groove 52. The mortise and tenon structure of the dovetail block 51 and the dovetail groove 52 has a strong structural stability, can withstand axial force, radial force and tilting force, reduce friction during movement, and improve the operating efficiency and stability of the inclined ejector mechanism 1.

[0048] When the tilting mechanism 1 starts to work, the dovetail block 51 on the tilting rod 3 will slide in the dovetail groove 52 on the slider 4 to ensure that the movement of the tilting rod 3 is accurately restricted and guided. The design of the dovetail block 51 and the dovetail groove 52 is simple, which can ensure the accurate alignment and stable movement between the tilting rod 3 and the slider 4, thereby ensuring the stable operation and precise operation of the tilting mechanism 1.

[0049] Reference Figure 5 and Figure 6 The screw member 6 includes a screw 61 disposed on the slider 4. In this embodiment, the screw 61 is vertically disposed. The slider 4 is provided with a mounting hole 41. The screw 61 is inserted into the slider 4 through the mounting hole 41 and is threadedly connected with the slider 4. The screw 61 is stuck in the mounting hole 41.

[0050] The dovetail block 51 and the inclined ejector rod 3 are jointly provided with a limiting groove 62. In this embodiment, the limiting groove 62 is arranged through the dovetail block 51 in the vertical direction and extends downward into the inclined ejector rod 3. The limiting groove 62 is communicated with the dovetail groove 52. The screw 61 first passes through the slider 4 and then is inserted into the limiting groove 62. The screw 61 is threadedly connected with the slider 4, and the screw 61 slides and contacts in the limiting groove 62.

[0051] The limiting groove 62 is formed by the dovetail block 51 and the inclined ejector rod 3, and passes through the dovetail block 51 and extends into the inclined ejector rod 3, which saves additional space design and makes the structure more compact; and can ensure that the screw 61 in the limiting groove 62 can accurately control the moving range of the inclined ejector rod 3;

[0052] A movable space 63 is left at the bottom of the screw 61 and the limiting groove 62; the movable space 63 can reduce the friction between the screw 61 and the limiting groove 62, and reduce the wear on the inner wall of the limiting groove 62 of the lift rod 3 during the movement of the screw 61, thereby extending the service life of the lift mechanism 1 and improving its stability and reliability;

[0053] When the inclined ejector mechanism 1 is working, in the initial state, the screw 61 is relatively located at the top of the limiting groove 62; when the inclined ejector rod 3 and the slider 4 are ejected from the mold, the inclined ejector rod 3 is driven to continue to move obliquely upward. During this process, the limiting groove 62 on the inclined ejector rod 3 slides relative to the screw 61, and then the inclined ejector rod 3 continues to move to exit the undercut structure 21 of the product 2. At this time, the screw 61 is relatively located at the bottom of the limiting groove 62, ensuring that the inclined ejector rod 3 is controlled during the movement to prevent it from detaching from the slider 4; when it is necessary to reset, the inclined ejector rod 3 is driven to reset and move obliquely backward. At this time, the limiting groove 62 on the inclined ejector rod 3 slides relatively along the screw 61, and the screw 61 returns to the top of the limiting groove 62, so that the slider 4 and the inclined ejector rod 3 return to the initial position, ready for the next operation, thereby achieving stable and efficient work;

[0054] The screw 61 achieves precise control of the moving stroke of the inclined ejector rod 3 by sliding in the limit groove 62, thereby ensuring the accuracy and stability of the separation and combination process of the inclined ejector rod 3 and the slider 4, and controlling the ejection, release and reset actions of the inclined ejector rod 3, thereby achieving the separation and combination of the product 2 and the mold; and the installation of the screw 61 is convenient and quick, and adjusting the position of the screw 61 can flexibly change the working stroke of the inclined ejector mechanism 1, adapt to products 2 and molds of different sizes and shapes, and improve the applicability and versatility of the inclined ejector mechanism 1.

[0055] The block 7 is also included. In this embodiment, the material of the block 7 includes but is not limited to copper or aluminum. The block 7 is disposed in the mounting hole 41 and plugged into the screw 61. The block 7 blocks the screw 61 in the mounting hole 41.

[0056] The top surface of the block 7 is flush with the top surface of the slider 4; thereby ensuring that the product 2 is in smooth contact with the surface of the slider 4 during molding, reducing the possibility of scratches or surface damage, and maintaining the integrity and quality of the product 2;

[0057] By designing a block 7 in the mounting hole 41 to be plugged into and fit with the screw 61, the screw 61 is sealed in the mounting hole 41. Such a design can ensure that the position of the screw 61 in the mounting hole 41 is fixed, and prevent it from accidentally moving or loosening during operation, thereby ensuring the stability and reliability of the tilting mechanism 1; and the design that the top surface of the block 7 is flush with the top surface of the slider 4 can ensure that the product 2 is in smooth contact with the surface of the slider 4 during molding, thereby maintaining the integrity and quality of the product 2.

[0058] Reference Figure 7 The slider 4 is provided with a reset groove 42, and the mold is provided with a reset convex portion 81. The reset groove 42 is plugged and matched with the reset convex portion 81, so as to realize the accurate reset of the slider 4 to the mold;

[0059] The reset groove 42 is provided with a guiding inclined surface 421, and the reset protrusion 81 is provided with a matching inclined surface 811. The guiding inclined surface 421 guides the reset protrusion 81 to enter the reset groove 42, and the guiding inclined surface 421 and the matching inclined surface 811 slide and abut against each other; through the design of sliding and abutting between the guiding inclined surface 421 and the matching inclined surface 811, the reset protrusion 81 on the mold can be guided to move along a predetermined path and insert into the reset groove 42 of the slider 4, thereby ensuring that the slider 4 and the lift rod 3 correctly return to the target position on the mold, improving the stability and controllability of the reset process of the lift mechanism 1, thereby ensuring the normal operation and production efficiency of the equipment;

[0060] When it is necessary to reset the tilted lift mechanism 1, the tilted lift rod 3 is driven to reset and move obliquely to the rear. At this time, the limit groove 62 on the tilted lift rod 3 slides relatively along the screw 61, so that the slider 4 and the tilted lift rod 3 return to the initial position; continue to drive the tilted lift rod 3 to move obliquely to the rear, driving the slider 4 to move together. When the reset groove 42 on the slider 4 encounters the reset protrusion 81 on the mold, the guiding bevel 421 and the matching bevel 811 guide the slider 4 and the tilted lift rod 3 to move along a predetermined path, thereby ensuring that the slider 4 and the tilted lift rod 3 return to the predetermined position on the mold, so as to effectively control and adjust the position of the tilted 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 tilted lift mechanism 1 and the mold, thereby ensuring the normal operation and stability of the equipment.

[0061] Reference Figure 8The present application also provides an injection mold, including the tilting ejector mechanism 1 as described above; after the injection molding is completed, the injection mold is opened and the release work is performed through the tilting ejector mechanism 1, and the sliding connection of the mortise and tenon structure 5 of the tilting ejector rod 3 and the slider 4 ensures smooth movement, thereby quickly ejecting the product 2 from the mold and improving production efficiency; the design of the screw member 6 limits the movement range of the tilting ejector rod 3 and the slider 4 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.

[0062] The injection mold further includes a mold core 8, and the inclined ejector mechanism 1 is disposed in the mold core 8 and slidably disposed in the mold core 8. In this embodiment, a reset protrusion 81 is disposed on the inner wall of the mold core 8 of the injection mold and is used in conjunction with the reset groove 42 of the slider 4.

[0063] A gap 9 is left between the inclined ejector rod 3 and the mold core 8. In the present embodiment, the inner wall of the mold core 8 is provided with a chamfered structure, thereby forming a gap 9 between the inclined ejector rod 3; 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 8, and it can also be operated more easily when maintenance or replacement is required; and it can also ensure that the inclined ejector mechanism 1 will not interfere with the mold core 8 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.

[0064] The implementation principle of the embodiment of the present application is as follows: the tilting 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 5, the screw member 6 and the reset groove 42 designed on the slider 4 and the tilting rod 3 can effectively realize the release and reset of the mechanism; and the screw member 6 of the present application is easy and quick to install, and the position of the screw 61 can be adjusted to change the working stroke of the tilting mechanism 1, so as to adapt to products 2 and molds of different sizes and shapes, thereby improving the applicability and versatility of the tilting mechanism 1;

[0065] When the inclined ejector mechanism 1 is working, in the initial state, the inclined ejector rod 3 and the slider 4 are connected with the dovetail groove 52 through the dovetail block 51 and are in a stationary state. At this time, the screw 61 is relatively located at the top of the limiting groove 62; when the injection mold is opened, the inclined ejector rod 3 is driven to move obliquely upward to eject, and the inclined ejector rod 3 will drive the slider 4 and the product 2 to eject together, separating the mold and the product 2. After the inclined ejector rod 3 and the slider 4 are moved out of the mold core 8 of the injection mold, the inclined ejector rod 3 continues to move. At this time, the inclined ejector rod 3 will move relatively to the side of the undercut structure 21 away from the product 2. During this process, the dovetail block 51 on the inclined ejector rod 3 will slide in the dovetail groove 52 on the slider 4 to ensure that the movement of the inclined ejector rod 3 is accurately restricted and guided, and the limiting groove 62 on the inclined ejector rod 3 slides relative to the screw 61. When the screw 61 slides relatively to the bottom of the limiting groove 62, the inclined ejector rod 3 stops moving and completely withdraws from the undercut structure 21 of the product 2 to complete the separation process.

[0066] When resetting is required, the inclined ejector rod 3 is driven to reset toward the oblique rearward direction. At this time, the limiting groove 62 on the inclined ejector rod 3 slides relatively along the screw 61, and the screw 61 returns to the top of the limiting groove 62, thereby realizing the reset control between the inclined ejector rod 3 and the slider 4; continue to drive the inclined ejector rod 3 to move toward the oblique rearward direction, driving the slider 4 to move together. When the reset groove 42 on the slider 4 encounters the reset protrusion 81 on the mold core 8 in the injection mold, the guiding bevel 421 and the matching bevel 811 guide the slider 4 and the inclined ejector rod 3 to move along a predetermined path, thereby ensuring that the slider 4 and the inclined ejector rod 3 return to the predetermined position on the mold core 8 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 8 and 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.

[0067] 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.
