Description
Technical Field
[0001] The present application relates to the field of die technology, and in particular, to a demoulding mechanism with a limiting component and an injection mould. Background Art
[0002] With the continuous progress and development of modern injection product technology, the design and manufacture of injection moulds are also constantly evolving and improving. Injection products usually have complex structures and precise requirements, which require that the forming mechanism in die design must be able to cope with diverse product forms and complex forming needs.
[0003] In the design of injection moulds, the slider mechanism is a common forming mechanism, and its main function is to form products with undercut structures, especially those products that are inconsistent with the main demoulding direction of the mould. The slider mechanism enables the mould to accurately form these products with complex structures through movement relative to the main demoulding direction of the mould.
[0004] However, with the complication of product design, some products may not only be different from the slider demoulding direction but also from the main demoulding direction of the mould. In this case, the traditional slider mechanism cannot meet the demoulding requirements for the complex structure of the product and cannot achieve complete demoulding. Therefore, there is an urgent need to develop a demoulding mechanism for products that require multiple demoulding directions to ensure that the mould can accurately and efficiently produce products that meet the design requirements. Utility Model Content
[0005] In order to develop a demoulding mechanism for products that require multiple demoulding directions, the present application provides a demoulding mechanism with a limiting component and an injection mould.
[0006] The demoulding mechanism with a limiting component and the injection mould provided by the present application adopt the following technical solutions:
[0007] A demoulding mechanism with a limiting component includes:
[0008] A slider for product forming;
[0009] A cam block and a plurality of lifters disposed on the slider, the lifters penetrate through the slider and are slidably disposed on the slider, one end of the lifter is slidably connected to the cam block, and the other end is used for forming the undercut features of the product;
[0010] A slide position limiting component disposed at the bottom of the cam block and abutting against the cam block, the slide position limiting component is used for supporting the cam block and for controlling the movement of the cam block;
[0011] During mold opening, the slider is driven to move away from the product, and the lifter pin will move away from the undercut and separate from the undercut. When the slide lock component releases the movement restriction on the lifter pin block, the slider drives the lifter pin block and the lifter pin to move together to complete the demolding of the product.
[0012] By adopting the above technical solution, through the combination and coordinated operation of the slider, the lifter pin block and the lifter pin, the forming position of the product and its undercut features can be controlled, and the smooth separation of the product during mold opening can be ensured, improving production efficiency and product quality. The design of the slide lock component ensures the release of the lifter pin block at the correct time, making the entire demolding process more reliable and stable; thus enabling the mechanism of the present application to be applicable to products that require multiple demolding directions, being able to flexibly handle the molding of products with different shapes and design requirements, and thus being able to be more widely applied to different production needs.
[0013] In a specific feasible embodiment, the lifter pin block is provided with a chute, one end of the lifter pin is arranged in the chute and slides in the chute, and the direction of the chute body is perpendicular to the moving direction of the slider.
[0014] By adopting the above technical solution, after injection molding is completed, the slider is driven to move away from the product, causing the slider to separate from the product. During this process, due to the sliding arrangement of the lifter pin, the lifter pin will perform relative movement along the direction of the chute, so that the lifter pin moves away from the undercut of the product and separates from the undercut. The design of the chute provided on the lifter pin block not only provides effective guidance and control for the movement of the lifter pin, but also ensures the product forming and demolding operations during the injection molding process.
[0015] In a specific feasible embodiment, the slide lock component includes a control rod, a limit block and a spring. The spring is arranged in the limit block, one end of the spring abuts against the limit block, and the other end extends out of the limit block. The spring is used to abut against and support the limit block to abut against the lifter pin block; one end of the control rod is fixedly connected to the slider, and the other end passes through the limit block, and a convex structure is provided at the end of the control rod passing through the limit block. The convex structure is used to squeeze the limit block and the spring;
[0016] During mold opening, the slider moves and drives the control rod to move together. When the control rod moves to the position where the convex structure contacts the limit block, the convex structure squeezes the limit block and the spring, releasing the abutting relationship between the limit block and the lifter pin block, so that the lifter pin block can move following the slider, and thus the lifter pin can move following the lifter pin block to separate from the product.
[0017] By adopting the above technical solution, through the combined use of the limiting block, spring and control rod, during injection molding, the spring can keep the limiting block in contact with the angled pin seat all the time, ensuring the stability of the whole mechanism to ensure the stable molding of the product; the design of the convex structure can control the release or setting of the limit when needed, while maintaining the stability and reliability of the system; the structure design of this slide position limiting component is simple, but it can meet the requirements for the slide position control of the angled pin seat, and can also maintain the simplicity of operation and maintainability.
[0018] In a specific feasible embodiment, an extrusion inclined surface is provided on one side of the convex structure close to the limiting block.
[0019] By adopting the above technical solution, by using the design of the extrusion inclined surface, the control rod can apply sufficient extrusion force to the limiting block with a relatively small force, making the extrusion force more concentrated and effective, and the existence of the extrusion inclined surface ensures the contact quality and stability between the limiting block and the angled pin seat, thereby improving the performance of the slide position limiting component.
[0020] In a specific feasible embodiment, a resisting surface is provided inside the slider, and the resisting surface is used to abut against the angled pin seat and drive the angled pin seat to move by abutting.
[0021] By adopting the above technical solution, when the slider moves to a specific mold opening position, the slide position limiting component releases the restriction on the angled pin seat, allowing the angled pin seat to move together with the slider. At this time, the resisting surface will contact and abut against the angled pin seat to move together, thereby driving the angled pin to move and realizing the separation of the angled pin from the product; the resisting surface not only limits the moving range of the slider, but also can drive the movement of the angled pin seat by abutting against the angled pin seat, and this linkage ensures the coordinated operation of the whole mechanism.
[0022] In a specific feasible embodiment, it further includes a pressing block. The angled pin seat is provided with a hanging platform structure, and the pressing block presses and fixes the angled pin seat on the slider, and the hanging platform structure slides between the slider and the pressing block.
[0023] By adopting the above technical solution, by using the hanging platform structure designed on the pressing block and the angled pin seat, during the movement process, the hanging platform structure on the angled pin seat can slide along the track between the slider and the pressing block, thereby being able to limit the movement of the angled pin seat on a specific track, ensuring the stability and reliability of the angled pin seat during the movement process; and by using the design of the pressing block, the installation process of the angled pin seat is simplified, the assembly efficiency is improved, and it is also convenient for subsequent maintenance and replacement.
[0024] In a specific feasible embodiment, it further includes a pressing plate. The pressing plate presses and fixes the angled pin on the slider, and the angled pin slides between the pressing plate and the slider.
[0025] By adopting the above technical solution, through the design of the pressure plate, the position of the angled pin on the slider can be controlled to ensure its relative sliding during movement according to the design requirements, and the stable movement of the angled pin on the slider can be guaranteed, avoiding unnecessary friction and position instability, thereby improving the overall reliability and performance; moreover, the use of the pressure plate simplifies the fixing process of the angled pin on the slider, improves the assembly efficiency, and also makes subsequent maintenance more convenient.
[0026] In a specific feasible embodiment, it further includes a driving member, the driving member is connected to the slider, and the driving member is used to drive the slider to move.
[0027] By adopting the above technical solution, through the effective connection and movement control of the driving member and the slider, the moving speed and position of the slider can be controlled, and the overall working efficiency can be improved, energy loss can be reduced, and a stable operating state can be ensured.
[0028] In a specific feasible embodiment, it further includes a restraint block, the restraint block is arranged on the side of the slider away from the product and abuts against the slider; when the mold is opened, the restraint block moves and releases the restriction on the slider.
[0029] By adopting the above technical solution, when the mold is closed, the restraint block is fixed in a position to restrict the movement state of the slider, ensuring that the slider remains stable during the injection molding or pressing of the product by the mold to ensure the shape and quality of the product; when the mold needs to be opened to take out the molded product, the restraint block can move to release the restriction on the slider, enabling the slider to move freely for the smooth removal of the product; by using the design of the restraint block, the movement state of the slider during the mold opening process can be effectively managed and controlled, thereby ensuring the smooth progress of the production process and improving the production efficiency and product quality.
[0030] An injection mold includes a demolding mechanism with a limiting component as described above.
[0031] In summary, the beneficial technical effects of the present application are as follows: Through the combination and collaborative work of the slider, the angled pin seat and the angled pin, and the row position limiting component, the present application can control the forming position of the product and its undercut features, and ensure the smooth separation of the product during mold opening, improving the production efficiency and product quality. The design of the row position limiting component ensures the release of the angled pin seat at the correct time, making the entire demolding process more reliable and stable; thus enabling the mechanism of the present application to be applicable to products that require multiple demolding directions, being able to flexibly handle the forming of products with different shapes and design requirements, and thus being able to be more widely applied to different production needs.

Specific embodiments
[0038] The following further describes the present application in detail with reference to the Figures 1-5 accompanying drawings.
[0039] Referring to Figure 1 and Figure 2 , an embodiment of the present application discloses a demolding mechanism with a limiting component for separating an injection mold 1 from a product 2. In this embodiment, the injection mold 1 includes an upper mold 11 and a lower mold 12, and a mold core 13 for forming the product 2 is embedded in the lower mold 12;
[0040] The demolding mechanism 3 with a limiting component is arranged on the lower mold 12. The demolding mechanism 3 with a limiting component includes a slider 4, an inclined pin seat 5 arranged on the slider 4, and a plurality of inclined pins 6. A part of the structure of the slider 4 is located in the mold core 13 and is used together with the mold core 13 for forming the product 2 and its undercuts. In this embodiment, two inclined pins 6 are provided. The two inclined pins 6 are both inclined and symmetrically arranged on the inclined pin seat 5. The inclined pins 6 penetrate through the slider 4 and are slidably arranged on the slider 4. One end of the inclined pin 6 is slidably connected to the inclined pin seat 5, and the other end passes through the slider 4 and extends into the mold core 13, respectively for forming the undercut features on both sides of the product 2;
[0041] The lifter seat 5 is provided with a sliding groove 51. In this embodiment, the sliding groove 51 can be, but is not limited to, a T-shaped groove. One end of the lifter 6 is clamped with the sliding groove 51 and slides in the sliding groove 51. The groove body direction of the sliding groove 51 is arranged along the y direction, and the moving direction of the slider 4 is along the x direction, that is, the groove body direction of the sliding groove 51 is perpendicular to the moving direction of the slider 4. When the slider 4 moves, due to the inclined design structure of the lifter 6 itself and the movement of the slider 4, the two lifters 6 will gradually move in opposite directions, and the two lifters 6 will gradually open and move away from each other, that is, the lifters 6 move to the side away from the undercut of the product 2 and withdraw from the undercut.
[0042] The demolding mechanism 3 further includes a lifter position limiting component 7. The lifter position limiting component 7 is arranged at the bottom of the lifter seat 5 and abuts against the lifter seat 5. The lifter position limiting component 7 is used to support the lifter seat 5 and control the movement of the lifter seat 5. One outer wall of the lifter seat 5 abuts against the inner wall of the slider 4, and there is a moving space 41 between the other outer wall and the inner wall of the slider 4. In this embodiment, the slider 4 is provided with a holding surface 42. In the initial state, there is this moving space 41 between the holding surface 42 and the lifter seat 5. The holding surface 42 is used to abut against and hold the lifter seat 5 to drive the lifter seat 5 to move.
[0043] When the slider 4 moves to a specific mold opening position, the lifter position limiting component 7 releases the restriction on the lifter seat 5 and allows the lifter seat 5 to move together with the slider 4. At this time, the holding surface 42 will contact and hold the lifter seat 5 to move together, thereby driving the lifter 6 to move and realizing the separation of the lifter 6 from the product 2. The holding surface 42 not only limits the moving range of the slider 4, but also can drive the lifter seat 5 to move by abutting against the lifter seat 5. This linkage ensures the coordinated operation of the entire mechanism.
[0044] After the injection molding is completed, when the mold is opened, the upper mold 11 is opened and moved away along the z direction, and the slider 4 is driven to move along the x direction toward the side away from the product 2. Due to the sliding connection between the lifter 6 and the lifter seat 5 and the slider 4, the two lifters 6 will respectively move along the y1 and y2 directions toward the side away from the undercut and separate from the undercut. During this process, the moving direction of the lifter 6 is perpendicular to the moving direction of the slider 4. During this process, due to the restriction of the lifter position limiting component 7, the lifter seat 5 remains relatively stationary. The slider 4 continues to move. When it reaches a specific mold opening position, the lifter position limiting component 7 releases the restriction on the lifter seat 5 and allows the lifter seat 5 to move together with the slider 4. At this time, the holding surface 42 will contact and hold the lifter seat 5 to move together, thereby driving the lifter 6 to move and separate from the product 2. Finally, the product 2 is demolded.
[0045] Through the combination and coordinated operation of the slider 4, the angle pin seat 5 and the angle pin 6, the forming position of the product 2 and its undercut features can be controlled, and the smooth separation of the product 2 during the mold opening process can be ensured, improving production efficiency and the quality of the product 2. The design of the slide limit component 7 ensures the release of the angle pin seat 5 at the correct time, making the entire demolding process more reliable and stable; thus enabling the mechanism of the present application to be applicable to products 2 that require multiple demolding directions, being able to flexibly handle the forming of products 2 with different shapes and design requirements, and thus being able to be more widely applied to different production needs.
[0046] Referring to Figure 2 and Figure 3 , the slide limit component 7 includes a control rod 71, a limit block 72 and a spring 73 provided in the slider 4. The limit block 72 abuts against the angle pin seat 5. In this embodiment, a fixing pin 74 is provided on the limit block 72, and the limit block 72 is fixed to the lower mold 12 through the fixing pin 74. There is a certain distance between the limit block 72 and the lower mold 12. The spring 73 is located inside the limit block 72 and sleeved on the fixing pin 74. One end of the spring 73 abuts against the limit block 72, and the other end abuts against the lower mold 12; one end of the control rod 71 is fixedly connected to the slider 4, and the other end passes through the limit block 72, and a convex structure 75 is provided at the end of the control rod 71 that passes through the limit block 72. The convex structure 75 is used to squeeze the limit block 72 to move away from the angle pin seat 5 to release the restriction on the angle pin seat 5;
[0047] On the side of the convex structure 75 close to the limit block 72, there is an extrusion inclined surface 76; thus enabling the control rod 71 to apply sufficient extrusion force to the limit block 72 with a relatively small force, making the extrusion force more concentrated and effective, and the existence of the extrusion inclined surface 76 ensures the contact quality and stability between the limit block 72 and the angle pin seat 5, thereby being able to improve the performance of the slide limit component 7. The extrusion inclined surface 76 can also facilitate the subsequent reset work;
[0048] After the injection molding is completed, the slider 4 is driven to move away from the product 2. The slider 4 will drive the control rod 71 to move. When the convex structure 75 on the control rod 71 moves to contact the limit block 72, the extrusion inclined surface 76 of the convex structure 75 will squeeze the limit block 72 and the spring 73, causing the limit block 72 to move away from the angle pin seat 5, changing the relative position and abutting relationship between the limit block 72 and the angle pin seat 5, and releasing the restriction on the angle pin seat 5, so that the angle pin seat 5 can drive the angle pin 6 to move with the slider 4, realizing the separation of the angle pin 6 and the product 2 to achieve the complete demolding of the product 2;
[0049] Through the combined use of the limit block 72, the spring 73, and the control rod 71, during injection molding, the spring 73 can keep the limit block 72 in contact with the angled pin seat 5 at all times, ensuring the stability of the entire mechanism to ensure the stable molding of the product 2. And during reset, the spring 73 can provide a driving force to enable the limit block 72 to return to its initial position to support the angled pin seat 5; the design of the convex structure 75 can control the release or setting of the limit when needed, while maintaining the stability and reliability of the system; the structure design of this row position limiting component 7 is simple, but it can meet the requirements for the row position control of the angled pin seat 5 and can also maintain the simplicity and maintainability of the operation.
[0050] The demolding mechanism 3 further includes a restraint block 31. The restraint block 31 is arranged on the side of the slider 4 away from the product 2. The restraint block 31 abuts against the slider 4. In this embodiment, one end of the restraint block 31 is fixed to the upper mold 11, and the other end is inserted into the lower mold 12 to abut against the slider 4; when the mold is closed, the restraint block 31 is fixed in a position to limit the moving state of the slider 4, ensuring that the slider 4 remains stable when the mold injects or presses the product 2 to ensure the shape and quality of the product 2; when the mold needs to be opened to take out the molded product 2, the movement of the upper mold 11 drives the movement of the restraint block 31 to release the restriction on the slider 4, enabling the slider 4 to move freely to facilitate the smooth removal of the product 2; through the design of the restraint block 31, the movement state of the slider 4 during the mold opening process can be effectively managed and controlled, thereby ensuring the smooth progress of the production process and improving the production efficiency and the quality of the product 2.
[0051] A driving member 10 is arranged on the side of the slider 4 away from the product 2. The driving member 10 is fixedly connected to the slider 4. In this embodiment, the driving member 10 includes but is not limited to an air cylinder, a hydraulic cylinder, and an oil cylinder. The driving member 10 is used to drive the slider 4 to move; through the effective connection and movement control between the driving member 10 and the slider 4, the moving speed and position of the slider 4 can be controlled, and the overall working efficiency can be improved, energy loss can be reduced, and a stable operating state can be ensured.
[0052] In this embodiment, the demolding mechanism 3 further includes an ejector pin 32. The ejector pin 32 passes through the mold core 13 and contacts the product 2. After both the slider 4 and the angled pin 6 are separated from the product 2, the product 2 is ejected out of the mold core 13 by driving the ejector pin 32 to complete demolding.
[0053] Refer to Figure 3 and Figure 4 As shown in [relevant figure numbers], the demolding mechanism 3 further includes a pressing block 8. The angled pin seat 5 is provided with a hanging platform structure 52. The pressing block 8 presses and fixes the angled pin seat 5 on the slider 4. The hanging platform structure 52 slides between the slider 4 and the pressing block 8. In this embodiment, the pressing block 8 includes but is not limited to being connected to the slider 4 by bolts;
[0054] During assembly, the inclined pin seat 5 is placed in the slider 4, the hanging platform structure 52 of the inclined pin seat 5 contacts the slider 4, and then the pressing block 8 is installed. The pressing block 8 and the slider 4 are connected and fixed by bolts. The pressing block 8 will abut the hanging platform structure 52 between the slider 4 and the pressing block 8 to complete the installation of the inclined pin seat 5. The design of the pressing block 8 simplifies the installation process of the inclined pin seat 5, improves the assembly efficiency, and is also convenient for subsequent maintenance and replacement.
[0055] During the movement, the hanging platform structure 52 on the inclined pin seat 5 can slide along the track between the slider 4 and the pressure block 8, thereby limiting the movement of the inclined pin seat 5 on a specific track and ensuring the stability and reliability of the inclined pin seat 5 during the movement.
[0056] Reference Figure 5 The demoulding mechanism 3 further includes a pressing plate 9, which presses and fixes the oblique pin 6 on the slider 4, and the oblique pin 6 slides between the pressing plate 9 and the slider 4. In this embodiment, the pressing plate 9 includes but is not limited to being connected to the slider 4 by bolts;
[0057] During assembly, one end of the inclined pin 6 is slidably connected with the slide groove 51 of the inclined pin seat 5, and the other end of the inclined pin 6 is passed through the slider 4, and then the pressing plate 9 is installed. The pressing plate 9 and the slider 4 are fixed by bolts. The pressing plate 9 will abut the inclined pin 6 between the slider 4 and the pressing plate 9 to complete the installation of the inclined pin 6; the use of the pressing plate 9 simplifies the fixing process of the inclined pin 6 on the slider 4, improves the assembly efficiency, and also makes subsequent maintenance more convenient;
[0058] During the movement, the design of the pressure plate 9 can control the position of the inclined pin 6 on the slider 4, ensuring that it slides relatively according to the design requirements during the movement, and ensuring the stable movement of the inclined pin 6 on the slider 4, avoiding unnecessary friction and position instability, thereby improving the overall reliability and performance.
[0059] The implementation principle of the embodiment of the present application is as follows: the mechanism of the present application can control the molding position of the product 2 and its undercut feature through the combination and coordinated work of the slider 4, the inclined pin seat 5, the inclined pin 6, and the sliding position limiting component 7, and ensure the smooth separation of the product 2 during the mold opening process, and can be used for products 2 that require multiple demolding directions, and can flexibly cope with the molding of products 2 with different shapes and design requirements, so that it can be more widely used in different production needs;
[0060] When the mold is closed, the bundle block 31 is fixed in a position to limit the movement of the slider 4, ensuring that when the mold is injection molding or pressing the product 2, the slider 4 remains stable to ensure the shape and quality of the product 2;
[0061] When the mold needs to be opened to take out the molded product 2, the upper mold 11 moves to drive the beam block 31 to move and release the restriction on the slider 4. The driving member 10 is activated, and the driving member 10 drives the slider 4 to move to the side away from the product 2. Due to the sliding connection between the inclined pin 6, the inclined pin seat 5 and the slider 4, the inclined pin 6 will move to the side away from the undercut, that is, the two inclined pins 6 will relatively open and move away from the undercut and separate from the undercut. During this process, since the limiting block 72 in the slide position limiting component 7 always supports and abuts against the fixed inclined pin seat 5, the inclined pin seat 5 remains relatively stationary;
[0062] The driving member 10 continues to drive the slider 4 to move. When reaching a specific mold opening position, the slide position limiting component 7 releases the restriction on the inclined pin seat 5. Specifically, the slider 4 will drive the control rod 71 in the slide position limiting component 7 to move. When the convex structure 75 on the control rod 71 moves to contact the limiting block 72, the pressing inclined surface 76 of the convex structure 75 will press the limiting block 72 and the spring 73, causing the limiting block 72 to move to the side away from the inclined pin seat 5, changing the relative position between the limiting block 72 and the inclined pin seat 5 and releasing the restriction on the inclined pin seat 5, so that the inclined pin seat 5 can drive the inclined pin 6 to move with the slider 4, realizing the separation of the inclined pin 6 from the product 2. Finally, by driving the ejector pin 32 to move upward, the ejector pin 32 ejects the product 2 out of the mold core 13, realizing the complete demolding of the product 2.
[0063] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
