Abstract
Description
Technical Field
[0001] The present application relates to the field of mold technology, and in particular to a bidirectional core-pulling mechanism in a slider and a mold. Background Art
[0002] Injection mold design and structural selection are crucial in the manufacturing of plastic products. As the shapes and functions of plastic products become increasingly complex, traditional injection mold structures are no longer sufficient to meet the manufacturing needs of these new plastic products. These products often possess unique geometric features and complex internal structures, requiring mold design to incorporate multiple core pulling methods to ensure smooth molding and easy demolding.
[0003] Sliders, a common functional component in injection molds, are often used to solve problems with angled holes or complex contours in parts. The slider design allows for core extraction in a specific direction during the injection molding process, ensuring that detailed parts of the plastic product are fully molded. However, when product features molded on the slider require core extraction in multiple directions, a slider with single-direction movement often fails to meet this requirement. This necessitates the addition of a core-extraction system in the slider design to achieve multi-directional core extraction.
[0004] To address this challenge, a slider mechanism capable of multi-directional core pulling must be designed. This mechanism must not only possess excellent structural stability and movement flexibility, but also ensure coordination between the various slider systems to avoid mold damage or molding defects caused by uncoordinated movement. Furthermore, the overall mold layout and processing technology must be considered to simplify operations during manufacturing and maintenance, thereby reducing production costs. Utility Model Content
[0005] In order to design a slider mechanism that can realize multi-directional core pulling, the present application provides a two-way core pulling mechanism and a mold in a slider.
[0006] The present application provides a bidirectional core-pulling mechanism in a slider and a mold adopting the following technical solutions:
[0007] A bidirectional core-pulling mechanism in a slider is used for demoulding a product. The bidirectional core-pulling mechanism in the slider comprises a slider, an oblique core-pulling insert and a sliding wedge. The slider and the oblique core-pulling insert are in contact with the product respectively.
[0008] The slider is connected to the oblique core-pulling insert via the sliding wedge, the sliding wedge is slidably connected to the oblique core-pulling insert, the slider and the sliding wedge move in the same direction, and an angle is formed between the moving direction of the slider and the moving direction of the oblique core-pulling insert;
[0009] When the mold is opened, the slider is driven to move, and the movement of the slider separates it from the product. When the slider moves, it will drive the sliding wedge to move together. The movement of the sliding wedge prompts the oblique core pulling insert to move along another inclined direction. The movement of the oblique core pulling insert separates it from the product, thereby realizing two-way core pulling.
[0010] By adopting the above-mentioned technical solution, the mechanism of the present application can realize that when the slider moves in one direction, the oblique core-pulling insert is prompted to move in the other direction at the same time, thereby completing the two-way core-pulling requirements of complex-shaped products. This mechanism ensures that all parts of the product can be demolded smoothly, reduces the scrap rate caused by molding defects, and helps to improve the consistency and quality of the product; by designing the sliding wedge and the oblique core-pulling insert into a sliding connection, the complexity of the mechanism is simplified, and the difficulty of mechanism design and manufacturing is reduced. The two-way core-pulling mechanism can be widely used in various types of injection molds, and can provide effective solutions for both simple and complex product designs to adapt to different production needs.
[0011] In a specific possible implementation scheme, the sliding wedge is provided with an inclined groove, the end of the inclined core-pulling insert away from the product is inserted into the inclined groove, the bottom surface of the inclined groove is set as an inclined surface, and the inclined core-pulling insert slides along the inclined surface.
[0012] By adopting the above technical solution, the design of the inclined groove enables the inclined core pulling insert to move naturally outward along the inclined surface when sliding, reducing the resistance during core pulling; and increases the flexibility of the inclined core pulling insert during sliding, so that it can slide more smoothly along the inclined surface, ensuring that parts with complex internal structures can be extracted, thereby improving the success rate of demolding and production efficiency.
[0013] In a specific possible implementation scheme, the inclined core-pulling insert includes an inclined ejector rod and a connecting block, one end of the inclined ejector rod is in contact with the product, and the other end is connected to the connecting block, and the connecting block is located in the inclined groove and slides in the inclined groove.
[0014] By adopting the above technical solution, the structure simplifies the design requirements of the mold. The way the connecting block slides in the inclined groove reduces the number of components of the mechanism. By adjusting the angle and length of the inclined ejector rod, it can adapt to plastic products of different shapes and complexities, thereby enhancing the versatility and adaptability of the mold.
[0015] In a specific possible implementation scheme, a slot is provided on the side wall of the inclined slot, and the connecting block is provided with a boss, which is stuck in the slot and slides and abuts in the slot, and the moving direction of the boss is the same as that of the connecting block.
[0016] By adopting the above technical solution and utilizing the cooperation between the boss and the slot, the connecting block is kept on a predetermined path during the sliding process, ensuring that it moves along the direction of the inclined slot, thereby reducing the lateral deviation of the connecting block. Through the design of the slot and boss, the connecting block can slide smoothly in the inclined slot, ensuring a fast and reliable core pulling effect.
[0017] In a specific possible implementation scheme, the inclined core-pulling insert is arranged at an angle of 5°-25° to the vertical direction.
[0018] By adopting the above technical solution, this angle design can effectively guide the plastic parts during the molding and demolding process, reducing the jamming phenomenon caused by the friction between the core puller and the plastic parts, thereby improving the working efficiency of the mold, shortening the molding cycle, and reducing production costs. In addition, the anti-jamming and fool-proofing designs can effectively reduce equipment damage caused by operational errors or jamming, thereby reducing equipment maintenance and replacement costs, and can help maintain product integrity, reduce defects, and improve product quality.
[0019] In a specific possible implementation scheme, it also includes a stroke limiting block, the slider is provided with a slide groove, the stroke limiting block is partially inserted into the slide groove and is slidably connected to the slide groove; the movement of the slider drives the sliding wedge block to move, and when the sliding wedge block moves to the stroke limiting block, the slider stops moving.
[0020] By adopting the above technical solution, when the slider starts to move, the movement of the slider causes the slide groove and the stroke limit block to displace relative to each other. When the sliding wedge moves to the stroke limit block, the movement of the slider is restricted, forming an effective termination mechanism. This design prevents the slider from exceeding the designed stroke and avoids potential mechanical damage or failure.
[0021] In a specific embodiment, a bundle block is further included. The bundle block is located on the side of the slider away from the product, and the bundle block abuts against the slider. When the mold is opened, the bundle block moves to release the movement restriction of the slider.
[0022] By adopting the above technical solution and utilizing the bundle block design, it is possible to effectively prevent the slider from accidentally moving when the mold is closed, thereby improving the safety of operation and the injection molding quality of the product. When the mold needs to be opened, the restriction of the slider can be released by simply moving the bundle block, greatly improving the flexibility and convenience of operation.
[0023] A mold includes a mold core, the mold core is provided with a product cavity, the mold includes a two-way core-pulling mechanism in a slider as described above, the slider and part of the structure of the inclined core-pulling insert are located in the product cavity of the mold core, and are used together with the product cavity to form the product.
[0024] By adopting the above technical solution and the combined design of the slider and the oblique core-pulling insert, the mold can form complex and fine product shapes, improve the molding accuracy, and the two-way core-pulling mechanism of the slider and the oblique core-pulling insert can quickly and effectively complete the core-pulling process, shorten the opening and closing time and removal time of the mold, and improve the overall production efficiency. This mold design is suitable for the molding needs of various materials and different products, and has good versatility and flexibility.
[0025] In a specific possible implementation scheme, the mold core is provided with a movable hole, the movable hole is connected to the inclined groove, the inclined ejector rod of the inclined core-pulling insert passes through the movable hole and is then inserted into the product cavity, and the inclined ejector rod slides and contacts in the movable hole.
[0026] By adopting the above technical solution, the presence of the movable hole combined with the design of the inclined groove limits the moving path of the inclined ejector rod, which means that during the core pulling operation, the inclined ejector rod can only move in a specific direction and angle, ensuring the stability and controllability of the entire core pulling process.
[0027] In a specific possible implementation manner, the mold core is further provided with a liquid channel hole, the liquid channel hole is communicated with the movable hole, and the liquid channel hole is used to inject lubricating liquid into the movable hole.
[0028] By adopting the above technical solution, the connection design between the liquid channel hole and the movable hole can ensure that the lubricating liquid can be accurately and effectively injected into the movable hole to provide lubrication. Good lubrication can make the movement of the inclined ejector rod faster and more stable, reduce friction, and improve the smoothness and efficiency of the core pulling operation, thereby improving the working efficiency of the mold and ensuring the stability of the mold and the high quality of the product.
[0029] To sum up, the beneficial technical effects of the present application are as follows: the bidirectional core-pulling mechanism in the slider of the present application adopts a combination design of a slider, an oblique core-pulling insert, a sliding wedge, a bundle block, and a stroke limiting block, which can realize that when the slider moves in one direction, the oblique core-pulling insert is prompted to move in the other direction at the same time, thereby completing the bidirectional core-pulling requirements of complex-shaped products, ensuring that all parts of the product can be smoothly demolded, thereby improving the consistency and quality of the product, and can simplify the complexity of the mechanism, reducing the difficulty of mechanism design and manufacturing. The bidirectional core-pulling mechanism can be widely used in various types of injection molds. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-6 This application is described in further detail.
[0038] Example 1
[0039] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a bidirectional core-pulling mechanism in a slider, which is used for demoulding a product. The bidirectional core-pulling mechanism in the slider includes a slider 1, an oblique core-pulling insert 2 and a sliding wedge 3. The slider 1 and the oblique core-pulling insert 2 are in contact with the product respectively. In this embodiment, the slider 1 and the sliding wedge 3 are both horizontally arranged, and the oblique core-pulling insert 2 is inclined. The slider 1 and the oblique core-pulling insert 2 are connected through the sliding wedge 3. The slider 1 and the sliding wedge 3 include but are not limited to being fixedly connected by bolts, and the sliding wedge 3 is slidably connected to the oblique core-pulling insert 2;
[0040] The slider 1 and the sliding wedge 3 move in the same direction. An angle A is formed between the moving direction of the slider 1 and the moving direction of the oblique core-pulling insert 2. In this embodiment, the slider 1 and the sliding wedge 3 move rightward along the horizontal direction x to separate from the product, and the oblique core-pulling insert 2 moves obliquely downward along the oblique direction v to exit from the product and separate from the product. In this embodiment, the angle formed between the horizontal direction x and the oblique direction v is the angle A, which includes but is not limited to 65°-85°.
[0041] During the core pulling operation, the slider 1 is driven to move rightward along the horizontal direction x. The movement of the slider 1 separates it from the molded product. During the movement of the slider 1, the movement of the slider 1 drives the sliding wedge 3 to move together. Since the sliding wedge 3 is slidingly connected to the oblique core pulling insert 2, the angle between the sliding wedge 3 and the oblique core pulling insert 2 during the movement process prompts the oblique core pulling insert 2 to move obliquely downward along another oblique direction v. As the slider 1 moves further, the oblique core pulling insert 2 successfully moves along its oblique direction v and separates from the product, thereby realizing the function of two-way core pulling and completing the demoulding of the product.
[0042] The design of this mechanism makes it possible for the slider 1 to move in the horizontal direction x while simultaneously prompting the oblique core-pulling insert 2 to move in another oblique direction v, thereby completing the two-way core-pulling requirements of complex-shaped products. This mechanism ensures that all parts of the product can be demoulded smoothly, reduces the scrap rate caused by molding defects, and helps to improve the consistency and quality of the product; by designing the sliding wedge 3 and the oblique core-pulling insert 2 as a sliding connection, the complexity of the mechanism is simplified, and the difficulty of mechanism design and manufacturing is reduced. The two-way core-pulling mechanism can be widely used in various types of injection molds.
[0043] The angle between the inclined core-pulling insert 2 and the vertical direction includes but is not limited to 5°-25°; this angle design can effectively guide the plastic parts during the molding and demolding process, reduce the jamming phenomenon caused by the friction between the core-pulling insert and the plastic parts, thereby improving the working efficiency of the mold, shortening the molding cycle, and reducing production costs. The anti-jamming and fool-proof design can effectively reduce equipment damage caused by operational errors or jamming, thereby reducing equipment maintenance and replacement costs, and can help maintain product integrity, reduce defects, and improve product quality.
[0044] Reference Figure 2 and Figure 3 The inclined core-pulling insert 2 includes an inclined ejector rod 21 and a connecting block 22. The inclined ejector rod 21 is connected to the connecting block 22. In this embodiment, the inclined ejector rod 21 and the connecting block 22 are integrally formed. The end of the inclined ejector rod 21 away from the connecting block 22 contacts the product.
[0045] The sliding wedge block 3 is provided with an inclined groove 31. The sliding block of the inclined core-pulling insert 2 is inserted into the inclined groove 31 and slides within the inclined groove 31. The bottom surface of the inclined groove 31 is provided with an inclined surface 32. The bottom surface of the sliding block abuts against the inclined surface 32, and the sliding block slides along the inclined surface 32. The design of the inclined groove 31 increases the flexibility of the inclined core-pulling insert 2 during the sliding process, allowing it to slide more smoothly along the inclined surface 32, ensuring that parts with complex internal structures can be extracted, thereby improving the success rate of demoulding and production efficiency.
[0046] In actual use, the design of the inclined core-pulling insert 2 can greatly improve the efficiency of core pulling through the oblique pulling of the inclined ejector rod 21, making the demoulding process faster and more effective. This structure simplifies the design requirements of the mold. The way the connecting block 22 slides in the inclined groove 31 reduces the number of components of the mechanism. By adjusting the angle and length of the inclined ejector rod 21, it can adapt to plastic products of different shapes and complexities, thereby enhancing the versatility and adaptability of the mold.
[0047] The latch 33 is provided on the opposite groove side wall of the inclined groove 31, and the latch 33 is arranged along the length direction of the inclined groove 31. In this embodiment, the inclined groove 31 and the latch 33 form a T-shaped groove, and the connecting block 22 is provided with a boss 23, and the boss 23 is arranged corresponding to the latch 33. The boss 23 is stuck in the latch 33 and slides and conflicts in the latch 33. The moving direction of the boss 23 is the same as the moving direction of the connecting block 22; the cooperation between the boss 23 and the latch 33 is used to keep the connecting block 22 on a predetermined path during the sliding process, ensuring that it moves along the direction of the inclined groove 31, thereby reducing the lateral deviation of the connecting block 22. Through the design of the latch 33 and the boss 23, the connecting block 22 can slide smoothly in the inclined groove 31, thereby improving the transmission efficiency of the inclined ejector 21 during operation and ensuring a fast and reliable core pulling effect;
[0048] During the core pulling operation, the slider 1 drives the sliding wedge 3 to move to the right along the horizontal direction x, and the movement of the sliding wedge 3 drives the inclined core pulling insert 2 to move. In this process, with the help of the inclined surface 32 of the inclined groove 31, the connecting block 22 of the inclined core pulling insert 2 moves and slides along the inclined surface 32 in the inclined groove 31, and the boss 23 of the connecting block 22 slides in the slot 33, so that the connecting block 22 remains on a predetermined path during the sliding process, ensuring that it moves along the direction of the inclined groove 31; as the connecting block 22 slides, the inclined push rod 21 is connected to the connecting block 22, and the connecting block 22 drives the inclined push rod 21 to slide relatively obliquely downward toward the side away from the product along the inclined direction v, so that the inclined push rod 21 of the inclined core pulling insert 2 is pulled out of the product and separated from the product, realizing the oblique core pulling operation.
[0049] The bidirectional core pulling mechanism in the slider further includes a stroke limiting block 4. The slider 1 is provided with a slide groove. The stroke limiting block 4 is partially inserted into the slide groove and is slidably connected to the slide groove.
[0050] During the core pulling operation, when the slider 1 starts to move, the movement of the slider 1 causes the slide groove and the stroke limiting block 4 to be displaced relative to each other. During the movement of the slider 1, it will drive the sliding wedge 3 to move together. When the sliding wedge 3 moves to the stroke limiting block 4, the movement of the slider 1 is restricted, forming an effective termination mechanism. This design prevents the slider 1 from exceeding the designed stroke and avoids potential mechanical damage or failure. The design of the slider 1, slide groove, stroke limiting block 4 and sliding wedge 3 can achieve precise control of the movement of the slider 1, ensuring the safety and stability of the equipment during operation.
[0051] The bidirectional core-pulling mechanism in the slider also includes a bundle block 5, which is located on the side of the slider 1 away from the product, and the bundle block 5 abuts against the slider 1; when the mold is closed, the bundle block 5 abuts against the slider 1 to limit the position of the slider 1, ensuring that the slider 1 remains stably in the preset position. When the mold is opened, the bundle block 5 moves to release the movement restriction of the slider 1, ensuring that the slider 1 can perform core pulling; the design of the bundle block 5 can effectively prevent the slider 1 from moving accidentally when the mold is closed, thereby improving the safety of operation and the injection molding quality of the product. In the process of opening the mold, the restriction of the slider 1 can be released by simply moving the bundle block 5, which greatly improves the flexibility and convenience of operation.
[0052] Reference Figure 4 and Figure 5 The present application also provides a mold. In this embodiment, the mold includes a movable mold and a fixed mold. The fixed mold is provided with a mold core 6. The mold core 6 is provided with a product cavity 7 for producing the product. The mold also includes the above-mentioned inner-two-way core-pulling mechanism in the slider. In this embodiment, the number of inner-two-way core-pulling mechanisms in the slider on the mold is designed according to the shape structure of the product produced by the actual mold. The mold can be designed with a single group or multiple groups of inner-two-way core-pulling mechanisms in the slider. In this embodiment, the mold is designed with three groups of inner-two-way core-pulling mechanisms in the slider.
[0053] In the bidirectional core-pulling mechanism within the slider: the slider 1, the oblique core-pulling insert 2, and the sliding wedge 3 are arranged on the fixed mold. Parts of the slider 1 and the oblique core-pulling insert 2 extend into the product cavity 7 of the mold core 6 and are used together with the product cavity 7 to form the product. In this embodiment, one end of the bundle block 5 is fixed to the movable mold, and the other end is inserted into the fixed mold to abut against the slider 1 to limit the position of the slider 1. One side of the travel limit block 4 is fixed to the fixed mold, and the other side is inserted into the slide groove of the slider 1.
[0054] The mold core 6 is provided with a moving hole 8, which is connected to the inclined groove 31 of the sliding wedge 3. The inclined ejector rod 21 of the inclined core pulling insert 2 passes through the moving hole 8 and is then inserted into the product cavity 7, and the inclined ejector rod 21 slides and conflicts in the moving hole 8; the existence of the moving hole 8 combined with the design of the inclined groove 31 limits the moving path of the inclined ejector rod 21, so that during the core pulling operation, the inclined ejector rod 21 can only move along a specific direction and angle, ensuring the stability and controllability of the entire core pulling process; and the design of the inclined ejector rod 21 sliding and conflicting in the moving hole 8 can control the friction force in the core pulling process to a certain extent. Appropriate friction can ensure that the inclined ejector rod 21 will not get stuck when moving, while providing sufficient support force to ensure its stable position in the cavity.
[0055] When the mold is opened, the mold is opened, and the movable mold moves upward along the vertical direction y, driving the bundle block 5 to move. After the bundle block 5 moves, the movement restriction of the slider 1 is released, and the core pulling work can be started at this time;
[0056] When the core pulling is working, the driving slider 1 moves to the right along the horizontal direction x. The movement of the slider 1 separates it from the formed product. The movement of the slider 1 causes the slide groove and the stroke limiting block 4 to be displaced relative to each other. During the movement of the slider 1, the movement of the slider 1 drives the sliding wedge 3 to move together. Since the sliding wedge 3 and the inclined core pulling insert 2 are slidingly connected, the inclined core pulling insert 2 will move obliquely downward along another inclined direction v during the movement of the sliding wedge 3. In this process, with the help of the inclined surface 32 of the inclined groove 31, the connecting block 22 of the inclined core pulling insert 2 moves and slides along the inclined surface 32 in the inclined groove 31. , the boss 23 of the connecting block 22 slides in the slot 33, so that the connecting block 22 remains on a predetermined path during the sliding process, ensuring that it moves along the direction of the inclined slot 31. As the connecting block 22 slides, the connecting block 22 drives the inclined ejector rod 21 to move, and the inclined ejector rod 21 slides relatively downward along the inclined direction v in the moving hole 8 toward the side away from the product, thereby pulling the inclined ejector rod 21 of the inclined core puller 2 out of the product and separating it from the product. When the sliding wedge block 3 moves to contact the stroke limiting block 4, the movement of the slider 1 is restricted, and the slider 1 stops moving, completing the demoulding work of the product;
[0057] The mold of the present application adopts a combination design of a slider 1, an oblique core-pulling insert 2, a sliding wedge block 3, a bundle block 5, and a stroke limiting block 4, so that the mold can form complex and fine product shapes, and improves the forming accuracy. The horizontal and oblique bidirectional core-pulling mechanism of the slider 1 and the oblique core-pulling insert 2 can quickly and effectively complete the core-pulling process, shorten the time for opening and closing and removing the mold, and improve the overall production efficiency; in addition, the design of the mold and the bidirectional core-pulling mechanism in the slider has a wide range of applicability, can meet the forming requirements of a variety of materials and different products, and exhibits good versatility and flexibility. Whether in the production of high-precision parts or in mass production, this mold design can provide a stable and reliable solution.
[0058] Example 2
[0059] Reference Figure 6 The difference between this embodiment and the first embodiment is that the mold core 6 is further provided with a liquid channel hole 9, which is connected to the movable hole 8 and is used to inject lubricating liquid into the movable hole 8;
[0060] The connection design between the liquid channel hole 9 and the movable hole 8 can ensure that the lubricating liquid can be accurately and effectively injected into the movable hole 8 to provide lubrication. Good lubrication can make the movement of the inclined ejector 21 faster and more stable, reduce friction, and improve the smoothness and efficiency of the core pulling operation, thereby improving the working efficiency of the mold and ensuring the stability of the mold and the high quality of the product.
[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
