Description

Technical Field

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

[0002] An injection mold is a tool used to manufacture plastic products during the injection molding process. The lifter mechanism is an auxiliary structure in the injection mold, usually used to help demould the product. The lifter mechanism usually includes a lifter, a guide sleeve, a guide column, a lifter seat and other components. The lifter mechanism can be tilted to achieve demoulding of the product when the mold is opened and closed.

[0003] During the injection molding process, the cavity formed by the product is closed, and the lifter will move obliquely along the guide sleeve of the guide column to push the product out of the mold cavity, thereby completing the demoulding operation. The lifter mechanism currently on the market usually uses an L-shaped groove or a T-shaped groove as the connection method between the lifter and the lifter seat; however, during the movement of the lifter, this connection method will cause friction between the lifter and the lifter seat, especially when the lifter is thin, the guide length of the L-shaped hanging platform or T-hanging platform of the lifter in the L-shaped groove or T-shaped groove is short, which is easy to get stuck during the ejection process and cause the lifter to break; this situation is particularly prominent in multi-cavity molds, increasing the risk of the lifter getting stuck or breaking, which not only affects the stability and service life of the mold, but also increases the mold maintenance cost and reduces production efficiency. Utility Model Content

[0004] In order to improve the problem that the existing tilting lift mechanism may get stuck or break, affecting the stability and service life of the entire mold, the present application provides a tilting lift mechanism and an injection mold.

[0005] The present application provides a tilting mechanism and an injection mold using the following technical solutions:

[0006] A tilting mechanism comprises a tilting rod, a connecting rod and a tilting seat, wherein the connecting rod connects the tilting rod and the tilting seat, and the connecting rod is rotatably connected to the tilting rod and the tilting seat through a first mortise and tenon structure and a second mortise and tenon structure respectively.

[0007] By adopting the above technical scheme, the connecting rod is connected to the inclined ejector rod through the first mortise and tenon structure, and is connected to the inclined ejector seat through the second mortise and tenon structure to form an integral structure; when the inclined ejector mechanism is working, the connecting rod, the inclined ejector rod and the inclined ejector seat can rotate relative to each other through the rotation of the first mortise and tenon structure and the second mortise and tenon structure, and the connecting rod can effectively guide and support the inclined ejector rod to ensure its stable movement in the horizontal direction, thereby improving the accuracy and efficiency of demoulding; the present application mainly adopts the design of two mortise and tenon structures to enable the inclined ejector rod to rotate flexibly during movement, effectively prevent the inclined ejector rod from getting stuck or broken during movement, and adapt to the movement requirements under different working conditions. The design of the two mortise and tenon structures is simple, and can also reduce the friction between the components, extend the service life of the inclined ejector mechanism, reduce maintenance costs, and ensure the stability and reliability of the inclined ejector mechanism, thereby improving the efficiency and safety of demoulding.

[0008] In a specific possible implementation manner, the first mortise and tenon structure includes a rotating portion provided on the inclined ejector rod and a rotating groove provided on the connecting rod, and the rotating portion is inserted into the rotating groove and rotates against the rotating groove.

[0009] By adopting the above technical scheme, when the inclined ejector mechanism starts to move, the rotating part on the inclined ejector rod is inserted into the rotating groove on the connecting rod and performs rotational resistance; this design enables the inclined ejector rod to rotate relative to the connecting rod during the movement while maintaining a firm connection, thereby achieving smooth movement of the inclined ejector rod; and by inserting the rotating part into the rotating groove and performing rotational resistance, the inclined ejector rod can be effectively prevented from getting stuck or broken due to displacement during the movement, thereby improving the reliability and stability of the inclined ejector mechanism; and compared with the traditional connection method, this design can reduce the space occupied by the connecting parts, making the inclined ejector mechanism more compact in design, which is conducive to working installation in a limited space; it can also be suitable for thinner inclined ejector rods, even if the inclined ejector rods are thin, they can still be firmly connected to the connecting rod through this connection method, and the structural strength of the inclined ejector rod itself can also be guaranteed.

[0010] In a specific possible implementation manner, the length of the rotating portion is smaller than the length of the rotating groove.

[0011] By adopting the above technical solution, the design that the length of the rotating part is smaller than the length of the rotating groove can ensure that when the tilting lift mechanism is working, the rotating part will not completely fill the rotating groove, thereby leaving a certain space during the rotation process. This design can provide a certain amount of clearance, so that the connection between the tilting lift rod and the connecting rod is more flexible, which is conducive to reducing friction and resistance, and reducing the risk of sticking or jamming; and it can be suitable for thinner tilting lift rods. Even if the tilting lift rod is thin, it can still be firmly connected to the connecting rod through this connection method, thereby ensuring the normal operation of the tilting lift mechanism.

[0012] In a specific possible implementation manner, the second mortise and tenon structure includes a rotating portion provided on the connecting rod and a rotating groove provided on the inclined top seat, and the rotating portion is inserted into the rotating groove and rotates to abut against the rotating groove.

[0013] By adopting the above technical solution, by inserting the rotating part into the rotating groove and rotating to resist, it can be ensured that the second mortise and tenon structure is firmly connected between the inclined roof seat and the connecting rod, providing reliable support and fixation, and can also reduce the friction of the second mortise and tenon structure during movement, reduce energy loss, and improve the efficiency of the entire inclined roof mechanism.

[0014] In a specific possible implementation mode, the outer surface of the rotating part is arranged to fit with the groove wall of the rotating groove, and the outer surface of the rotating part is arranged to fit with the groove wall of the rotating groove.

[0015] By adopting the above technical scheme, the fitting arrangement of the outer surface and the groove wall can ensure close contact between the rotating part and the rotating groove, and between the rotating part and the rotating groove, increase the contact area between the connecting parts, and improve the stability and reliability of the connection; and the fitting arrangement can reduce the gap between the rotating part and the rotating groove, and between the rotating part and the rotating groove, reduce friction, reduce energy loss, and enhance the transmission effect, thereby improving the efficiency of the inclined top mechanism.

[0016] In a specific possible implementation manner, a limiting portion is provided on the groove wall of the rotation groove and the rotating groove, and the limiting portion is clamped on the rotation portion and the rotating portion.

[0017] By adopting the above technical solution, the limiting parts arranged on the rotating groove and the rotating groove are clamped on the rotating part and the rotating part; such a design can ensure that the connection between the rotating part and the rotating groove, and between the rotating part and the rotating groove is more firm and stable. At the same time, the relative position of the rotating part and the rotating groove, and the rotating part and the rotating groove can be controlled through the design of the limiting part to prevent excessive rotation or disengagement, thereby improving the working efficiency and reliability of the tilting mechanism.

[0018] In a specific feasible implementation scheme, a first inclined surface is provided on a side of the inclined lift rod close to the rotating part and a side of the connecting rod close to the rotating part, and a second inclined surface is provided on a side of the limiting part close to the rotating groove and the notch of the rotating groove; the second inclined surface limits the rotation stroke of the inclined lift rod, and the inclination angle of the first inclined surface is greater than the inclination angle of the second inclined surface.

[0019] By adopting the above technical scheme, the design of using the second inclined surface to limit the rotational stroke of the inclined lift rod and the connecting rod can be suitable for the use of thinner inclined lift rods, and the rotational stroke of the inclined lift rod can be limited to prevent the inclined lift rod from excessive rotation and breakage; and the setting of the inclination angle of the first inclined surface on the inclined lift rod and the connecting rod is greater than the inclination angle of the second inclined surface on the limiting part, which helps the rotating part and the rotating part to rotate freely in the rotating groove and the rotating groove without being interfered by the inclined lift rod and the connecting rod, thereby ensuring the normal operation of the inclined lift mechanism without interference, thereby making the inclined lift rod smoother during rotation and reducing energy loss.

[0020] In a specific possible implementation scheme, it further includes a pin, and the rotating portion of the connecting rod is connected to the inclined top seat through the pin.

[0021] By adopting the above technical solution, the pin is used to fix the connecting rod and the inclined top seat together, so that the connecting rod can only rotate about the axis and will not move downward or even fall due to gravity when the axis is perpendicular to the ground.

[0022] In a specific possible implementation mode, a clearance gap is left between the connecting rod, the inclined ejector rod and the inclined ejector seat.

[0023] By adopting the above technical solution and leaving an appropriate retreat gap, when the lift mechanism is working, the retreat gap can prevent the connecting rod from interfering with the lift rod or the lift seat when the lift rod retreats too far horizontally.

[0024] An injection mold comprises the tilting ejector mechanism as described above.

[0025] By adopting the above technical solution, after the injection molding is completed, the mold needs to be separated to take out the molded product. In this process, the rotation of the inclined ejector mechanism causes the inclined ejector rod to move horizontally, exerting a certain force on the product, ejecting the product, and causing the product to be separated from the mold cavity. This design can reduce the friction between the product and the mold, making the product demolding smoother and faster, avoiding product damage or deformation, thereby improving production efficiency and reducing production costs. It is also beneficial to protect the mold and product and extend the service life of the injection mold.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The tilting mechanism of the present application mainly adopts the design of two connecting parts, namely, the rotating part and the rotating groove, and the rotating part and the rotating groove, so that the tilting rod can rotate flexibly during movement, which can effectively prevent the tilting rod from getting stuck or broken during movement, reduce maintenance costs, and extend the service life of the tilting mechanism; and can adapt to the movement requirements under different working conditions, and can also ensure the stability and reliability of the tilting mechanism, and improve the efficiency and safety of demoulding;

[0028] 2. The application scenarios of the inclined ejector mechanism of the present application are wide. By using the connection method of the first mortise and tenon structure, the connection between the inclined ejector rod and the connecting rod can be completed by adding a rotating part to cooperate with the rotating groove on the connecting rod, without the need to drill holes on the inclined ejector rod like the existing hinged rotation connection method, thereby helping to ensure the structural strength of the inclined ejector rod itself. In addition, the inclined ejector mechanism of the present application can realize rotation connection through the first mortise and tenon structure regardless of whether the thickness of the inclined ejector rod is thick or thin, which is particularly suitable for thinner inclined ejector rods. The rotation connection of the inclined ejector rod is realized without increasing the number of holes on the inclined ejector rod, further ensuring the structural strength of the inclined ejector rod.

[0029] 3. The injection mold of the present application uses the inclined ejector mechanism of the present application, which can reduce the friction between the product and the mold, make the product demolding smoother and faster, avoid product damage or deformation, thereby improving production efficiency and reducing production costs. It is also beneficial to protect the mold and product and extend the service life of the injection mold. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Reference Figure 1 and Figure 2The embodiment of the present application discloses a tilting ejection mechanism, which is used to eject the product when the mold is opened and separate the mold from the product; the tilting ejection mechanism 1 includes a tilting ejection rod 2, a connecting rod 3 and a tilting ejection seat 4. In this embodiment, the tilting ejection rod 2 is provided with an outer shape structure consistent with the product structure, and the tilting ejection rod 2, the connecting rod 3 and the tilting ejection seat 4 are all arranged vertically;

[0038] The connecting rod 3 is arranged between the inclined ejector rod 2 and the inclined ejector seat 4, and the connecting rod 3 connects the inclined ejector rod 2 and the inclined ejector seat 4. The connecting rod 3 is rotatably connected with the inclined ejector rod 2 and the inclined ejector seat 4 respectively through the first mortise and tenon structure 5 and the second mortise and tenon structure 6; in this embodiment, the inclined ejector mechanism 1 is ejected in the vertical direction, and the connecting rod 3 and the inclined ejector rod 2 rotate relative to the inclined ejector seat 4. At this time, the inclined ejector rod 2 moves relatively in the horizontal direction to exert a certain force on the product, thereby pushing the product out of the mold smoothly. In this embodiment, the horizontal movement and retreat distance of the inclined ejector rod includes but is not limited to 6mm;

[0039] A retreat gap 9 is left between the connecting rod 3 and the inclined ejector rod 2 and the inclined ejector seat 4. In this embodiment, the width of the retreat gap 9 includes but is not limited to 0.2-2 mm. By leaving an appropriate retreat gap 9, when the inclined ejector mechanism 1 is working, the retreat gap 9 can prevent the connecting rod 3 from interfering with the inclined ejector rod 2 or the inclined ejector seat 4 when the horizontal retreat distance of the inclined ejector rod 2 is too large.

[0040] Before working, the connecting rod 3 is connected to the inclined ejector rod 2 through the first mortise and tenon structure 5, and is connected to the inclined ejector seat 4 through the second mortise and tenon structure 6 to form an integral structure; when the inclined ejector mechanism 1 is working, the connecting rod 3, the inclined ejector rod 2 and the inclined ejector seat 4 can rotate relative to each other through the rotation of the first mortise and tenon structure 5 and the second mortise and tenon structure 6, and the connecting rod 3 can effectively guide and support the inclined ejector rod 2 to ensure its stable movement in the horizontal direction, thereby improving the accuracy and efficiency of demoulding; the design of the two connecting parts allows the inclined ejector rod 2 to rotate flexibly during movement, which can effectively prevent the inclined ejector rod 2 from getting stuck or broken during movement, and can adapt to the movement requirements under different working conditions. The design of the two mortise and tenon structures can reduce the friction between the components, extend the service life of the inclined ejector mechanism 1, reduce maintenance costs, and ensure the stability and reliability of the inclined ejector mechanism 1, thereby improving the efficiency and safety of demoulding.

[0041] Reference Figure 1 and Figure 2 The first mortise and tenon structure 5 includes a rotating portion 51 provided on the inclined ejector rod 2 and a rotating groove 52 provided on the connecting rod 3. In this embodiment, the longitudinal cross-section of the rotating portion 51 is circular, the rotating portion 51 is inserted into the rotating groove 52, and the rotating portion 51 rotates and abuts against the rotating groove 52;

[0042] The outer surface of the rotating part 51 is arranged to fit with the groove wall of the rotating groove 52; thereby, the rotating part 51 and the rotating groove 52 are in close contact, the contact area between the connecting parts is increased, and the stability and reliability of the connection are improved; and the fitting arrangement can reduce the gap between the rotating part 51 and the rotating groove 52, reduce friction, reduce energy loss, and enhance the transmission effect, thereby improving the efficiency of the tilting mechanism 1;

[0043] The length of the rotating portion 51 is smaller than the length of the rotating groove 52; this ensures that when the tilting mechanism 1 is working, the rotating portion 51 will not completely fill the rotating groove 52, thereby leaving a certain amount of space during the rotation process. This design can provide a certain amount of play, making the connection between the tilting rod 2 and the connecting rod 3 more flexible, which is conducive to reducing friction and resistance, and reducing the risk of stagnation or jamming; and the connection method of the first mortise and tenon structure 5 can be applied to thinner tilting rods 2. Even if the tilting rod 2 is thin, it can still be firmly connected to the connecting rod 3 through this connection method, ensuring the normal operation of the tilting mechanism 1;

[0044] When the tilting mechanism 1 starts to move, the rotating part 51 on the tilting rod 2 is inserted into the rotating groove 52 on the connecting rod 3 and rotates against it. This design allows the tilting rod 2 to rotate relative to the connecting rod 3 during the movement while maintaining a firm connection, thereby achieving smooth movement of the tilting rod 2. Moreover, by inserting the rotating part 51 into the rotating groove 52 and rotating against it, the tilting rod 2 can be effectively prevented from getting stuck or broken due to displacement during the movement, thereby improving the reliability and stability of the tilting mechanism 1. Compared with the traditional connection method, this design can reduce the space occupied by the connecting parts, making the tilting mechanism 1 more compact in design, which is conducive to working installation in a limited space. It can also be suitable for thinner tilting rods 2. Even if the tilting rods 2 are thin, they can still be firmly connected to the connecting rod 3 through this connection method, and the structural strength of the tilting rod 2 itself can also be guaranteed.

[0045] Reference Figure 1 and Figure 2 The second mortise and tenon structure 6 includes a rotating portion 61 provided on the connecting rod 3 and a rotating groove 62 provided on the inclined top seat 4. In this embodiment, the longitudinal cross-section of the rotating portion 51 is circular, the rotating portion 61 is inserted into the rotating groove 62, and the rotating portion 61 rotates and abuts against the rotating groove 62;

[0046] The outer surface of the rotating part 61 is arranged in close contact with the groove wall of the rotating groove 62; thereby, the rotating part 61 and the rotating groove 62 are in close contact, the contact area between the connecting parts is increased, and the stability and reliability of the connection are improved; and the close contact arrangement can reduce the gap between the rotating part 61 and the rotating groove 62, reduce friction, reduce energy loss, and enhance the transmission effect, thereby improving the efficiency of the tilting mechanism 1;

[0047] The pin 63 is also included. The rotating portion 61 on the connecting rod 3 is connected to the inclined top seat 4 through the pin 63. In this embodiment, the pin 63 is arranged horizontally, passes through the rotating portion 61 and the rotating groove 62, and is rotatably arranged on the inclined top seat 4, so as to realize the connection and fixation between the connecting rod 3 and the inclined top seat 4. By means of the arrangement of the pin 63, the pin 63 fixes the connecting rod 3 and the inclined top seat 4 together, so that the connecting rod 3 can only rotate in the axial direction, and will not move downward or even fall due to gravity when the axis is perpendicular to the ground.

[0048] In this embodiment, the length of the rotating portion 61 is equal to the length of the rotating groove 62, and the rotating portion 61 fills the entire rotating groove 62; this design ensures that there is no gap between the rotating portion 61 and the rotating groove 62, so that the pin 63 can pass through the rotating portion 61 without affecting its own strength. By filling the entire rotating groove 62 with the rotating portion 61, it can be ensured that the connection of the pin 63 has sufficient structural strength, thereby ensuring the stability and reliability of the tilting mechanism 1 when working;

[0049] Before work, the rotating part 61 on the connecting rod 3 is inserted into the rotating groove 62 of the inclined top seat 4, and then the pin 63 is passed through the rotating part 61 and the rotating groove 62, so that the pin 63 is rotatably set on the inclined top seat 4; during work, the rotating part 61 rotates and abuts in the rotating groove 62. This design enables the connecting rod 3 to rotate relative to the inclined top seat 4 during movement, ensuring that the second mortise and tenon structure 6 is firmly connected between the inclined top seat 4 and the connecting rod 3, providing reliable support and fixation, and can also reduce the friction of the second mortise and tenon structure 6 during movement, reduce energy loss, and improve the efficiency of the entire inclined top mechanism 1.

[0050] Reference Figure 2 and Figure 3 Two limiting parts 7 are provided on the groove walls of the rotating groove 52 and the rotating groove 62, and the two limiting parts 7 in the same groove are arranged opposite to each other. In the present embodiment, the limiting parts 7 are protruding structures, and the limiting parts 7 are both stuck on the rotating part 51 and the rotating part 61; thereby ensuring that the connection between the rotating part 51 and the rotating groove 52, and between the rotating part 61 and the rotating groove 62 is more firm and stable. At the same time, the relative positions of the rotating part 51 and the rotating groove 52, and the rotating part 61 and the rotating groove 62 can be controlled through the design of the limiting parts 7 to prevent excessive rotation or disengagement, thereby improving the working efficiency and reliability of the tilting mechanism 1.

[0051] Reference Figure 2 and Figure 3A first inclined surface 8 is provided on one side of the inclined ejector rod 2 close to the rotating portion 51 and on one side of the connecting rod 3 close to the rotating portion 61, and a second inclined surface 71 is provided on one side of the limiting portion 7 close to the notch of the rotating groove 52 and the rotating groove 62; the second inclined surface 71 limits the rotation stroke of the inclined ejector rod 2; thus, it can be suitable for the use of a thinner inclined ejector rod 2, and the second inclined surface 71 limits the rotation stroke of the inclined ejector rod 2 to prevent the inclined ejector rod 2 from being broken due to excessive rotation;

[0052] The inclination angle of the first inclined surface 8 is greater than the inclination angle of the second inclined surface 71. In the present embodiment, the inclination angle is the angle between the first inclined surface 8 and the second inclined surface 71 relative to the horizontal plane. The inclination angle of the first inclined surface 8 is greater than the inclination angle of the second inclined surface 71, and the angle range includes but is not limited to 5°-25°. Through the above-mentioned design method, the rotating part 51 and the rotating part 61 can rotate freely in the rotating groove 52 and the rotating groove 62 without being interfered by the inclined lift rod 2 and the connecting rod 3, thereby ensuring the normal operation of the inclined lift mechanism 1 without interference, so that the inclined lift rod 2 can rotate more smoothly during the rotation process and reduce energy loss.

[0053] The inclined lift mechanism 1 of the present application has a wide range of application scenarios. The connection method of the first mortise and tenon structure 5 is utilized, so that the connection between the inclined lift rod 2 and the connecting rod 3 can be completed by adding a rotating part 51 to cooperate with the rotating groove 52 on the connecting rod 3, without the need to drill holes on the inclined lift rod 2 like the existing hinged rotation connection method, thereby helping to ensure the structural strength of the inclined lift rod 2 itself. In addition, the inclined lift mechanism 1 of the present application can achieve rotational connection through the first mortise and tenon structure 5 regardless of the thickness of the inclined lift rod 2. It is particularly suitable for thinner inclined lift rods 2, such as inclined lift rods 2 with a thickness of 3-4mm. The rotational connection of the inclined lift rod 2 can be achieved without increasing the number of holes on the inclined lift rod 2, thereby further ensuring the structural strength of the inclined lift rod 2.

[0054] Reference Figure 4 and Figure 5 The present application also provides an injection mold, including the tilting ejector mechanism 1 as described above. In this embodiment, the injection mold includes a mold core 10, the tilting ejector mechanism 1 is vertically arranged, and a tilting ejector rod 2 of the tilting ejector mechanism 1 passes through the mold core 10. The tilting ejector rod 2 slides and abuts against the mold core 10. In this embodiment, the mold core 10 and the tilting ejector rod 2 together form an outer shape structure consistent with the product structure;

[0055] In this embodiment, please refer to Figure 4 When the injection mold is being molded, the lift mechanism 1 is in a stationary state, and the top of the lift rod 2 of the lift mechanism 1 is flush with the top of the core 10 of the injection mold, together forming an appearance structure consistent with the product structure; please refer to Figure 5When the inclined ejector mechanism 1 is ejected, the connecting rod 3 realizes the horizontal movement of the inclined ejector rod 2 during the demoulding process through the rotation of the rotating part 51 and the rotating part 61. The inclined ejector rod 2 exerts a certain force on the product to eject the product and cause the product to be separated from the mold core 10. This design can reduce the friction between the product and the mold, making the product demoulding smoother and faster, avoiding product damage or deformation, thereby improving production efficiency and reducing production costs. At the same time, it is also beneficial to protect the mold and the product and extend the service life of the injection mold.

[0056] The implementation principle of the embodiment of the present application is as follows: the present application mainly adopts the design of two mortise and tenon structures of the rotating part 51 and the rotating groove 52, and the rotating part 61 and the rotating groove 62, so that the inclined ejector rod 2 can rotate flexibly during movement, which can effectively prevent the inclined ejector rod 2 from getting stuck or broken during movement, reduce maintenance costs, and extend the service life of the inclined ejector mechanism 1; and can adapt to the movement requirements under different working conditions, and can also ensure the stability and reliability of the inclined ejector mechanism 1, and improve the efficiency and safety of demoulding;

[0057] Before working, insert the rotating part 61 on the connecting rod 3 into the rotating groove 62 of the inclined ejector seat 4, and then pass the pin 63 through the rotating part 61 and the rotating groove 62, so that the pin 63 is rotatably set on the inclined ejector seat 4, so as to realize the rotational connection between the connecting rod 3 and the inclined ejector seat 4, and then insert the rotating part 51 on the inclined ejector rod 2 into the rotating groove 52 on the connecting rod 3, so as to realize the rotational connection between the inclined ejector rod 2 and the connecting rod 3, thereby forming an integral structure; then install the entire inclined ejector mechanism 1 on the injection mold, so that the inclined ejector rod 2 of the inclined ejector mechanism 1 passes through the mold core 10, and the top end of the inclined ejector rod 2 is flush with the top end of the mold core 10 of the injection mold, together forming an appearance structure consistent with the product structure;

[0058] During demoulding, the inclined ejector mechanism 1 is ejected, and the connecting rod 3 can rotate relative to the inclined ejector rod 2 and the inclined ejector seat 4 through the rotation of the rotating part 51 and the rotating part 61. The connecting rod 3 can effectively guide and support the inclined ejector rod 2 to ensure its stable movement in the horizontal direction. The inclined ejector rod 2 applies a certain force to the product to eject the product, prompting the product to separate from the mold core 10, thereby realizing the demoulding of the product; the injection mold uses the inclined ejector mechanism 1 of the present application to reduce the friction between the product and the mold, making the product demoulding smoother and faster, avoiding product damage or deformation, thereby improving production efficiency and reducing production costs. At the same time, it is also beneficial to protect the mold and product and extend the service life of the injection mold.

[0059] 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.
