Description

Technical Field

[0001] This invention relates to the field of injection molded product manufacturing, and more particularly to a demolding mechanism and an injection mold. Background Technology

[0002] In the injection molding process, some products often have undercut features on the sides due to structural design requirements. Demolding such structures is a key challenge in injection molding. The slider in the traditional demolding mechanism can only move in one direction, which cannot adapt to the complex shape of the undercut when used alone, making it difficult to complete the core-pulling molding in one go. Therefore, it is necessary to add a slider-angled core-pulling structure to the demolding mechanism, so as to achieve core-pulling demolding of the undercut area through the angled movement of the slider.

[0003] However, existing slider-type oblique core-pulling demolding mechanisms have obvious limitations: most mechanisms can only achieve oblique core-pulling action in a single direction, and cannot complete the synchronous core-pulling of multiple sides or multiple sets of undercuts of the product at one time. It is necessary to use two or more sliders to cooperate step by step to complete the overall core-pulling process, which significantly increases the overall complexity of the demolding mechanism and also increases the difficulty of parts processing and assembly. At the same time, motion interference or synchronization deviation is prone to occur during the multi-slider linkage process, which poses a risk of structural instability and makes it difficult to meet the high-efficiency and stable production requirements of complex undercut injection molded products. Summary of the Invention

[0004] The embodiments of the present invention provide a demolding mechanism and an injection mold to achieve core pulling in different directions in one go. The structure is simple, easy to process, and has high structural stability, thereby improving product quality and efficiency.

Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Reference Figures 1a to 7 The figure illustrates an embodiment of the demolding mechanism and injection mold of the present invention. The demolding mechanism includes a first slider assembly 1, a second slider assembly 2, and a third slider assembly 3. The second slider assembly 2 is slidably connected to the first slider assembly 1, and is located below the first slider assembly 1, and has a mounting groove 21. The third slider assembly 3 is located within the mounting groove 21 and is slidably connected to the second slider assembly 2 and the first slider assembly 1. During demolding, the first slider assembly 1 moves along the demolding direction, causing the second slider assembly and the third slider assembly 3 to move along the demolding direction.

[0033] Specifically, the demolding mechanism is mainly used for demolding injection molded products during the production process to prevent undercutting from occurring on the side of the product. This embodiment provides a demolding mechanism with a simple structure, high structural stability, and the ability to complete core-pulling actions in different directions at once, thereby improving product quality.

[0034] The demolding mechanism includes a first slider assembly 1, a second slider assembly 2, and a third slider assembly 3. The first slider assembly 1 is used for core pulling in one direction and drives the second slider assembly 2 and the third slider assembly 3 to move. The second slider assembly 2 is used for core pulling in another direction and can also drive the third slider assembly 3 to move along the demolding direction. The second slider assembly 2 is located below the first slider assembly 1 and is slidably connected to the first slider assembly 1. The second slider assembly 2 is provided with a mounting groove 21 for mounting the third slider assembly 3, thereby improving the integration of the demolding mechanism. The third slider assembly 3 is installed in the mounting groove 21 and is slidably connected to both the first and second slider assemblies.

[0035] During demolding, the fixed template moves along the demolding direction to drive the first slider assembly 1 to move along the demolding direction. Then, the first slider assembly 1 drives the second slider assembly 2 and the third slider assembly 3 to move along the demolding direction, thereby realizing the core pulling action in different directions in one go.

[0036] During mold closing, the fixed mold plate presses the first slider assembly 1 and the second slider assembly 2 to reset the first slider assembly 1 and the second slider assembly 2. At the same time, the first slider assembly 1 presses the third slider assembly 3 to reset.

[0037] Therefore, this application integrates the first slider assembly 1, the second slider assembly 2, and the third slider assembly 3 together, so that each slider assembly can complete the core-pulling movement along different directions, thereby solving the problem that injection molded products need to be pulled out along different directions at the same time. Moreover, the demolding mechanism has a simple structure, is easy to assemble, and has high structural stability, thereby improving product quality and production efficiency when producing injection molded products.

[0038] In one embodiment, reference is made to Figures 1a to 4As shown, the first slider assembly 1 includes a first slider 11, a slider seat 12, and a first inclined guide post 13. One side of the first slider 11 is fixedly connected to the slider seat 12. The slider seat 12 is provided with a first groove 111, and the first groove 111 is slidably connected to the first inclined guide post 13. Specifically, the first slider assembly 1 includes a first slider 11, a slider seat 12, and a first inclined guide post 13. The first slider 11 is the main body of the first slider assembly 1 and is used to drive the second slider assembly 2 and the third slider assembly 3 to move. The slider seat 12 is used to connect the first slider 11 and the first inclined guide post 13, so that the first slider 11 is driven by the first inclined guide post 13. The first inclined guide post 13 is used to push the first slider 11 to move along the mold ejection or mold closing direction.

[0039] One side of the first slider 11 is fixedly connected to the slider seat 12, and the slider seat 12 is provided with a first groove 111. The first groove 111 is used to install the first inclined guide post 13. The first groove 111 and the first inclined guide post 13 are slidably connected, that is, the first inclined guide post 13 moves up and down in the first groove 111, thereby driving the first slider 11 to move obliquely upward or obliquely downward, so that the first slider 11 moves along the mold ejection or mold closing direction.

[0040] Therefore, in this embodiment, the first slider 11 and the first inclined guide post 13 are connected by the slider seat 12. The first inclined guide post 13 is moved by the fixed template, which in turn moves the first slider 11. The first slider 11 moves along the mold exit direction and along the mold closing direction, which facilitates the mold exit and injection of the injection molded product and improves the product quality.

[0041] More specifically, during demolding, the first inclined guide post 13 pushes the first slider 11, thereby causing the first slider 11 to move along the demolding direction, realizing the core-pulling action of the first slider assembly 1; during mold closing, the fixed template presses the locking surface on the back of the first slider 11, causing the first slider 11 to reset.

[0042] In a specific embodiment, refer to Figures 1a to 4As shown, the first slider 11 is provided with a first placement groove 112 and a second placement groove 113 spaced apart. The first placement groove 112 is slidably connected to the second slider assembly 2, and the second placement groove 113 is slidably connected to the third slider assembly 3. Specifically, the first slider 11 is slidably connected to the second slider assembly 2, and the first slider 11 is also slidably connected to the third slider assembly 3. The first slider 11 is provided with a first placement groove 112 and a second placement groove 113, which are spaced apart. The first placement groove 112 is slidably connected to the second inclined guide post 23 of the second slider assembly 2. The second inclined guide post 23 is the power source of the second slider 22 of the second slider assembly 2. That is, the first slider 11 and the second slider 22 are connected through the second inclined guide post 23. When the first slider 11 moves, it drives the second inclined guide post 23 to move, thereby driving the second slider 22 to move, and finally realizing the core-pulling action of the second slider assembly 2. The second placement groove 113 is slidably connected to the third inclined guide post 32 of the third slider assembly 3. The third inclined guide post 32 is the power source of the third slider 31 of the third slider assembly 3. That is, the first slider 11 and the third slider 31 are connected through the third inclined guide post 32. When the first slider 11 moves, it drives the third inclined guide post 32 to move, thereby driving the third slider 31 to move, and finally realizing the core-pulling action of the third slider assembly 3.

[0043] Therefore, in this embodiment, by connecting the first slider 11 and the second slider assembly 2 in the first placement slot 112, and connecting the first slider 11 and the third slider assembly 3 in the second placement slot 113, the first slider 11 moves, simultaneously driving the second slider assembly 2 and the third slider assembly 3, and finally achieving the multi-directional core pulling action in one go. The demolding mechanism has a simple structure and is easy to assemble.

[0044] In one embodiment, reference is made to Figures 1a to 3d , Figure 5As shown, the second slider assembly 2 includes a second slider 22 and a second inclined guide post 23. The second slider 22 is provided with a second sliding groove 221, which extends along the length direction of the second slider 22. The two ends of the second inclined guide post 23 are slidably connected to the second sliding groove 221 and the first placement groove 112, respectively. Specifically, the second slider assembly 2 includes a second slider 22 and a second inclined guide post 23. The second slider 22 is the main body of the second slider assembly 2, and the core-pulling action is achieved by moving the second slider 22. The second slider 22 is provided with a second groove 221, which is used to connect the second inclined guide post 23 and the second slider 22. The second groove 221 extends along the length direction of the second slider 22 and is located on the side of the second slider 22 near the first slider 11. The second groove 221 is formed by a downward indentation on one side of the second slider 22. The second inclined guide post 23 is used to connect the first slider 11 and the second slider 22, so that the second slider 22 is driven by the first slider 11 through the second inclined guide post 23. One end of the second inclined guide post 23 is slidably connected to the first placement groove 112, and the other end of the second inclined guide post 23 extends toward the second groove 221 and is slidably connected to the second groove 221.

[0045] During demolding, the first slider 11 moves toward the demolding direction, thereby driving the second inclined guide post 23 to move toward the demolding direction. At this time, the second inclined guide post 23 moves from one end of the second slide groove 221 to the other end until the second inclined guide post 23 moves to the other end of the second slide groove 221. At this time, the second inclined guide post 23 drives the second slider 22 to move toward the demolding direction, thereby realizing the core-pulling action of the second slider assembly 2.

[0046] In this embodiment, the first slider 11 and the second slider 22 are connected by the second sliding groove 221 on the second slider 22 and the second inclined guide post 23, so that the first slider 11 moves and drives the second slider 22 to move, thereby realizing a single core pulling action in different directions. The structure is simple and the stability is high.

[0047] In a specific embodiment, refer to Figures 1a to 3d , Figure 5As shown, the second slider assembly 2 further includes a locking block 24, which is fixed on the fixed template and located on one side of the second slider 22 in the demolding direction. Specifically, the second slider assembly 2 further includes a locking element. The locking block 24 is used to lock the second slider 22 during mold closing and injection molding. The locking block 24 is fixed on the fixed template and is located on one side of the second slider 22 in the mold exit direction. When the second slider 22 is in the mold opening direction, the fixed template drives the locking block 24 to move in the mold exit direction. At the same time, the second slider 22 moves in the mold exit direction under the action of the second inclined guide post 23, that is, the second slider 22 moves towards the locking block 24. The moving distance of the second slider 22 is less than or equal to the distance from the initial position of the second slider 22 to the locking block 24. When the second slider 22 is in the mold closing direction, the fixed template drives the locking block 24 to move towards the second slider 22. The locking block 24 presses the second slider 22 to make the second slider 22 move until the second slider 22 is reset, that is, the second slider 22 moves to the initial position.

[0048] In this embodiment, the locking block 24 is used to reset the second slider 22, which has a simple structure and high stability.

[0049] In another embodiment, reference Figures 1a to 3d , Figure 5 As shown, the second slider assembly 2 further includes a second limiting block 25, which is fixedly connected to the moving template. The second slider 22 is provided with a first limiting groove 222, which extends from one side of the second slider 22 along the length direction of the second slider 22. The first limiting groove 222 is slidably connected to the second limiting block 25, and the bottom wall of the first limiting groove 222 is engaged with the second limiting block 25.

[0050] Specifically, the second slider assembly 2 further includes a second limiting block 25, which limits the movement distance of the second slider 22. The second limiting block 25 is located on one side of the second slider 22 in the demolding direction, fixed to the moving template, and slidably connected to the second slider 22. A first limiting groove 222 is provided on the side of the second slider 22 near the locking block 24. The first limiting groove 222 extends from one side of the second slider 22 in the opposite direction to the demolding direction and extends along the length of the second slider 22. The second limiting block 25 is slidably connected to the first limiting groove 222. When the second slider 22 moves in the demolding direction under the action of the second inclined guide post 23, the first limiting groove 222 and the second limiting block 25 slide relative to each other until the bottom wall of the first limiting groove 222 engages with the second limiting block 25, at which point the second slider 22 stops moving, thus stopping the core-pulling action of the second slider assembly 2. The bottom wall of the first limiting groove 222 refers to the side of the first limiting groove 222 that is away from the locking block 24.

[0051] This embodiment improves the stability and quality of the core-pulling process of the second slider assembly 2 by cooperating with the second limiting block 25 and the first limiting groove 222.

[0052] In one embodiment, reference is made to Figures 5 to 7 As shown, the third slider assembly 3 includes a third slider 31 and a third inclined guide post 32. The third slider 31 is provided with a third sliding groove 311. The two ends of the third inclined guide post 32 are slidably connected to the third sliding groove 311 and the second placement groove 113, respectively. Specifically, the third slider 31 includes a third slider 31 and a third inclined guide post 32. The third slider 31 is the main body of the third slider assembly 3, and the core-pulling action is achieved by moving the third slider 31. The third slider 31 is provided with a third groove 311, which is used to connect the third inclined guide post 32 and the third slider 31. The third groove 311 extends along the height direction of the third slider 31 and is located on the side of the third slider 31 close to the first slider 11. The third groove 311 is formed by a downward indentation on one side of the third slider 31. The third inclined guide post 32 is used to connect the first slider 11 and the third slider 31, so that the third slider 31 is driven by the first slider 11 through the third inclined guide post 32. One end of the third inclined guide post 32 is slidably connected to the second placement groove 113, and the other end of the third inclined guide post 32 extends toward the third groove 311 and is slidably connected to the third groove 311.

[0053] During demolding, the first slider 11 moves in the demolding direction, thereby driving the third inclined guide post 32 to move in the demolding direction. At the same time, the locking surface of the first slider 11 against the third slider 31 is released, and the third inclined guide post 32 drives the third slider 31 to move in the demolding direction, thereby realizing the core-pulling action of the third slider assembly 3.

[0054] When the mold is closed, the first slider 11 moves until the first slider 11 presses against the locking surface of the third slider 31, so that the third slider 31 is reset.

[0055] In this embodiment, the first slider 11 and the third slider 31 are connected by the third inclined guide post 32, thereby enabling the first slider 11 to move and drive the third slider 31 to move, thus realizing a single core-pulling action in different directions. The structure is simple and the stability is high.

[0056] In one embodiment, reference is made to Figures 5 to 7 As shown, the third slider assembly 3 further includes a guide block 33 and a slider insert 34. The guide block 33 is fixed to one side of the third slider 31, and the slider insert 34 is located between the third slider 31 and the groove wall of the mounting groove 21. The slider insert 34 is provided with a guide groove 341, which is slidably connected to the guide block 33. Specifically, the third slider assembly 3 further includes a guide block 33 and a slider insert 34. The guide block 33 is used to guide the slider insert 34 during demolding; the slider insert 34 is used to realize the core-pulling action in another direction of the product; the guide block 33 is fixed to one side of the third slider 31 and is located between the third slider 31 and the slider insert 34, connecting the third slider 31 and the slider insert 34, so that when the third slider 31 moves in the demolding direction, the guide block 33 can drive the slider insert 34 to move in the demolding direction. The slider insert 34 is located between the third slider 31 and the wall of the mounting groove 21, that is, the slider insert 34 moves between the side wall of the third slider 31 and the mounting groove 21; the slider insert 34 is provided with a guide groove 341 on one side near the guide block 33, the guide groove 341 extends along the height direction of the slider insert 34, and the guide groove 341 and the guide block 33 are correspondingly arranged so that the guide groove 341 and the guide block 33 are slidably connected, so that when the third slider 31 moves, it drives the guide block 33 to move, and then drives the slider insert 34 to move, thereby realizing the core pulling action and the reset action of the slider insert 34.

[0057] This embodiment improves the core-pulling accuracy of the third slider assembly 3 by additionally setting the slider insert 34, thereby further improving product quality. Moreover, the third slider assembly 3 has a simple structure and is easy to assemble.

[0058] More specifically, the slider insert 34 in this embodiment has a certain tilt angle, that is, the slider insert 34 is tilted in the mounting groove 21, so that the slider insert 34 moves tilted when it moves.

[0059] In a specific embodiment, refer to Figures 6 to 7 As shown, the third slider 31 has a fourth groove 312 on one side. The third slider assembly 3 also includes a slanted top insert 35 and a slanted top slider 36. One end of the slanted top slider 36 is slidably connected to the fourth groove 312, and the other end passes through the opening of the fourth groove 312 and is fixedly connected to the slanted top insert 35. Specifically, the third slider 31 also has a fourth groove 312, which is located on the side of the third slider 31 away from the slider insert 34. The fourth groove 312 is formed by an inward recess on one side of the third slider 31, and has an opening facing the slanted top insert 35.

[0060] The third slider assembly 3 further includes an inclined top insert 35 and an inclined top slider 36. The inclined top insert 35 is used for the core-pulling action of the product's buckle in another direction. The inclined top slider 36 is used to drive the inclined top insert 35 to move. One end of the inclined top slider 36 is slidably connected to the fourth slide groove 312, and the other end of the inclined top slider 36 passes through the opening of the fourth slide groove 312 and is fixedly connected to the inclined top insert 35. The inclined top insert 35 is located on the other side of the third slider 31 relative to the slider insert 34.

[0061] During demolding, the second slider 22 drives the third slider 31 to move along the demolding direction, so that the third slider 31 drives the inclined top insert 35 to move along the demolding direction through the inclined top slider 36.

[0062] When the mold is closed, the third slider 31 will press against the inclined top slider 36 to move, thereby driving the inclined top insert 35 to reset.

[0063] This embodiment achieves core pulling in another direction of the product by setting the inclined top insert 35 and the inclined top slider 36, thereby improving the core pulling accuracy of the third slider assembly 3 and further improving the product quality. Moreover, the third slider assembly 3 has a simple structure and is easy to assemble.

[0064] In another embodiment, reference Figures 6 to 7As shown, the third slider assembly 3 further includes a third limiting block 37, which is fixedly connected to the moving template. The third slider 31 is provided with a second limiting groove 313, which extends from one side of the third slider 31 along the length direction of the third slider 31. The second limiting groove 313 is slidably connected to the third limiting block 37, and the bottom wall of the second limiting groove 313 is engaged with the third limiting block 37.

[0065] Specifically, the third slider assembly 3 further includes a third limiting block 37, which limits the movement distance of the third slider 31. The third limiting block 37 is located on one side of the third slider 31 in the demolding direction, fixed to the moving template, and slidably connected to the third slider 31. A second limiting groove 313 is provided on one side of the third slider 31, extending from one side of the third slider 31 in the opposite direction to the demolding direction, and extending along the length of the third slider 31. The third limiting block 37 is slidably connected to the second limiting groove 313. When the third slider 31 moves in the demolding direction under the action of the third inclined guide post 32, the second limiting groove 313 and the third limiting block 37 slide relative to each other until the bottom wall of the second limiting groove 313 engages with the third limiting block 37, at which point the third slider 31 stops moving, thus stopping the core-pulling action of the third slider assembly 3. The bottom wall of the second limiting groove 313 refers to the side of the second limiting groove 313 that is away from the slider seat 12.

[0066] This embodiment improves the stability and quality of the core-pulling process of the third slider assembly 3 by cooperating with the third limiting block 37 and the second limiting groove 313.

[0067] In a specific embodiment, refer to Figure 4As shown, one side of the slider seat 12 is provided with a protrusion 121, and the first slider assembly 1 also includes a first limiting block 14. The first limiting block 14 is fixedly connected to the moving template and slidably connected to one side of the slider seat 12. The first limiting block 14 is engaged with the protrusion 121. Specifically, one side of the slider seat 12 is provided with a protrusion 121, which is formed by the outward protrusion of one side of the slider seat 12 and extends along the height direction of the slider seat 12. The protrusion 121 is used to limit the movement position of the first slider 11. The first slider assembly 1 also includes a first limiting block 14, which is used to engage with the protrusion 121 to limit the movement stroke of the first slider 11. The first limiting block 14 is fixedly connected to the moving template and is located on one side of the slider seat 12. One side of the first limiting block 14 abuts against one side of the slider seat 12 and the first limiting block 14 is slidably connected to the slider seat 12, so that when the slider seat 12 and the first slider 11 move, the first limiting block 14 and the slider seat 12 can slide relative to each other until the first limiting block 14 and the protrusion 121 engage.

[0068] During demolding, the first inclined guide post 13 drives the first slider 11 and the slider seat 12 to move along the demolding direction, that is, the first slider 11 and the slider seat 12 move toward the first limiting block 14 until the protrusion 121 engages with the first limiting block 14, at which point the slider seat 12 stops moving, causing the first slider 11 to stop moving, thus completing the core-pulling action of the first slider assembly 1.

[0069] Therefore, this embodiment limits the travel of the first slider 11 by setting the protrusion 121 and the first limiting block 14, thereby preventing the first slider 11 from moving excessively and affecting the stability of the core-pulling process.

[0070] This embodiment also provides an injection mold (not shown in the figure), which includes a demolding mechanism. The demolding mechanism can be any demolding mechanism provided by this invention. Since the specific structure and working principle of the demolding mechanism have been described in detail in the previous specification, they will not be repeated here for the sake of brevity.

[0071] The injection mold in this embodiment uses the demolding mechanism provided by the present invention. The demolding mechanism can complete the core pulling action in different directions in one go. It has a simple structure, is easy to process, and has high structural stability, thereby improving the production quality and efficiency of the injection mold and reducing production costs.

[0072] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
