Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a positioning structure for an anti-misalignment injection mold. Background Technology

[0002] In the field of injection molding, precise mold closing between the stationary and moving molds is crucial for ensuring product quality. Traditional injection molds typically use guide pillars and bushings for guidance and positioning. However, in actual production, especially in large molds or precision injection molding applications, guide pillars and bushings alone cannot completely eliminate minor misalignments between the moving and stationary molds. Such misalignments can lead to defects such as flash, uneven wall thickness, and dimensional errors, severely impacting product quality and production efficiency.

[0003] Furthermore, during high-pressure injection molding, the enormous injection pressure of the molten plastic tends to attempt to open the mold. If there is no effective locking mechanism after mold closing, the mold may experience slight backward movement or displacement, which can also cause product quality problems. Therefore, there is an urgent need for a positioning structure that can provide additional locking force after mold closing and effectively prevent mold misalignment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art. Therefore, one objective of this utility model is to provide a positioning structure for an anti-misalignment injection mold, disposed between a fixed mold and a moving mold, comprising: at least one set of conical guide components, including a positioning groove disposed on one of the fixed mold or the moving mold, and a positioning cone disposed on the other mold, wherein the positioning cone and the positioning groove are adapted to each other during mold closing to form a conical surface fit;

[0005] At least one locking assembly includes a locking block disposed on a fixed mold and a slider disposed on a moving mold and adapted to the locking block, the slider being slidably disposed within the moving mold and driven by an elastic element to give the slider a preload force in the direction of the locking block;

[0006] During the mold closing process, the moving mold gradually moves toward the fixed mold, and the slider abuts against the end face of the locking block and gradually compresses the elastic element. When the end face of the fixed mold is in contact with the end face of the moving mold, the compressed elastic element pushes the slider to insert into the locking block, so that the fixed mold and the moving mold are locked together.

[0007] Preferably, the end face of the locking block is gradually inclined toward the fixed mold.

[0008] Preferably, the locking block has a insertion groove that extends through the end face of the locking block and corresponds to the slider.

[0009] Preferably, the moving mold has a fixing groove, the shape of which is adapted to the locking block.

[0010] Preferably, the moving mold is further provided with a sliding groove, which is located on the side of the fixed groove and communicates with the fixed groove, and the slider is slidably disposed within the slider.

[0011] Preferably, the moving mold is further provided with at least two placement slots, which are respectively located at the top and bottom of the slide and are connected to the slide. The length of the placement slots is less than that of the slide.

[0012] Preferably, a limiting block is provided in the storage slot, one end of the limiting block is slidably disposed in the storage slot, and the other end is connected to the slider.

[0013] Preferably, the elastic element is disposed in the storage groove, with one end of the elastic element connected to the limiting block and the other end connected to the inner wall of the storage groove.

[0014] Preferably, the positioning cone is disposed on the fixed mold, and the positioning groove is disposed on the moving mold.

[0015] Preferably, the moving mold is further provided with a through hole, one end of which is connected to the slide groove and the other end of which penetrates the side of the moving mold. A pull rod is provided in the through hole, one end of which is connected to the slider and the other end of which extends to the outside of the moving mold.

[0016] The above-mentioned solution of this utility model includes at least the following beneficial effects: Preliminary guiding and positioning stage: When the moving mold begins to move towards the fixed mold, the conical guide component set on the mold first starts to work; the positioning cone will be guided into the corresponding positioning groove first, and the relative position of the moving mold and the fixed mold will be automatically corrected and guided by the unique self-centering characteristics of the conical surface, eliminating most of the circumferential and radial deviations, and realizing preliminary precision pre-positioning.

[0017] Contact Compression and Energy Storage Stage: As the mold closing action continues, the locking component begins to engage; the slider mounted on the moving mold, under the continuous preload force provided by the elastic element, will first abut against the end face of the locking block mounted on the fixed mold; since the moving mold is still advancing, the slider cannot immediately insert, and therefore, under the obstruction of the locking block end face, it overcomes the force of the elastic element and slides and contracts into the moving mold. This process continuously compresses the elastic element, allowing it to store elastic potential energy;

[0018] Final fitting and locking stage: When the end faces of the moving mold and the fixed mold are fully fitted and the mold closing end point is reached, the slider is aligned with the space (such as the insertion slot) on the locking block under the drive of the elastic element.

[0019] At this moment, the elastic element that has been compressed to the maximum extent releases its stored potential energy instantly, forcefully pushing the slider outward so that it can be stably and reliably inserted into the inside of the locking block.

[0020] By combining the conical guide component with the elastic locking component, the conical guide is responsible for the rough and fine positioning during the mold closing process, while the locking component is responsible for the final fixation at the mold closing end point, forming a dual insurance mechanism of positioning and locking, which greatly improves the alignment accuracy and reliability of mold closing and fundamentally prevents misalignment.

[0021] The locking component's action is fully integrated into the mold closing process, automatically completed using mechanical structure without external control. After mold closing, the slider and locking block form a rigid connection, which can effectively resist the huge mold expansion force generated during injection molding, prevent the mold cavity from undergoing micro-expansion deformation, thereby ensuring the stability of product dimensions and eliminating defects such as flash.

[0043] The positioning structure of an anti-misalignment injection mold according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings. The structure is located between the fixed mold and the moving mold.

[0044] Please refer to Figures 1-8. In this embodiment, it includes: at least one set of conical guide components 3, which includes a positioning groove 301 disposed on one of the fixed mold 1 or the moving mold 2, and a positioning cone 302 disposed on the other mold. The positioning cone 302 and the positioning groove 301 are adapted to each other and form a conical fit when the mold is closed; at least one set of locking components 4, which includes a locking block 401 disposed on the fixed mold 1, and a slider 402 disposed on the moving mold 2 that is adapted to the locking block 401. The slider 402 is slidable. The slider 402 is dynamically disposed within the moving mold 2 and driven by the elastic element 403, so that the slider 402 has a preload force in the direction of the locking block 401; during the mold closing process, the moving mold 2 gradually moves towards the fixed mold 1, the slider 402 abuts against the end face of the locking block 401 and gradually compresses the elastic element 403, when the end face of the fixed mold 1 and the end face of the moving mold 2 are in contact, the compressed elastic element 403 pushes the slider 402 to insert into the locking block 401, so that the fixed mold 1 and the moving mold 2 are locked together;

[0045] Preliminary guiding and positioning stage: The moving mold 2 begins to move towards the fixed mold 1. First, the conical guide component 3 set on the mold starts to work; the positioning cone 302 will first be guided into the corresponding positioning groove 301. Utilizing the unique self-centering characteristics of the cone, it automatically corrects and guides the relative position of the moving mold 2 and the fixed mold 1, eliminating most of the circumferential and radial deviations, and achieving preliminary precision pre-positioning.

[0046] Contact Compression and Energy Storage Stage: As the mold closing action continues, the locking component 4 begins to engage; the slider 402 mounted on the moving mold 2, under the continuous preload provided by the elastic element 403, will first abut against the end face of the locking block 401 mounted on the fixed mold 1; since the moving mold 2 is still advancing, the slider 402 cannot immediately insert, and therefore, under the obstruction of the end face of the locking block 401, it overcomes the force of the elastic element 403 and slides and contracts into the moving mold 2. This process continuously compresses the elastic element 403, allowing it to store elastic potential energy;

[0047] Final fitting and locking stage: When the end faces of the moving mold 2 and the fixed mold 1 are fully fitted and the mold closing end point is reached, the slider 402 is aligned with the space (such as the insertion slot 404) on the locking block 401 under the drive of the elastic element 403. At this time, the elastic element 403, which is compressed to the maximum extent, releases its stored potential energy instantly and forcefully pushes the slider 402 outward so that it is stably and reliably inserted into the inside of the locking block 401.

[0048] By combining the conical guide component 3 with the elastic locking component 4, the conical guide is responsible for the rough and fine positioning during the mold closing process, while the locking component 4 is responsible for the final fixation at the mold closing end point, forming a dual insurance mechanism of positioning and locking, which greatly improves the alignment accuracy and reliability of mold closing and fundamentally prevents misalignment.

[0049] The action of the locking component 4 is fully integrated into the mold closing process and is automatically completed by the mechanical structure without external control. After the mold is closed, the slider 402 and the locking block 401 form a rigid connection, which can effectively resist the huge mold expansion force generated during injection molding, prevent the mold cavity from undergoing micro-expansion deformation, thereby ensuring the stability of the product dimensions and eliminating defects such as flash.

[0050] In this embodiment, the end face of the locking block 401 is gradually inclined toward the fixed mold 1;

[0051] When the inclined end face contacts the end of the slider 402, a smooth guide slope is formed. During the mold closing process, the slider 402 slides across the inclined surface from the initial contact with the locking block 401 to the complete compression. This is a gradual and linear force process. This effectively avoids the violent impact and hard impact that may be generated by planar contact, greatly reduces the wear of the contact end of the slider 402 and the locking block 401, and improves the service life and reliability of the locking assembly 4. The inclined surface structure can effectively decompose the vertical mold closing force generated during mold closing into a component force (normal force) perpendicular to the inclined surface and a component force parallel to the inclined surface. The component force parallel to the inclined plane provides the driving force for the slider 402 to smoothly and effortlessly retract and slide into the moving mold 2. This makes the compression action of the slider 402 natural, effortless, and synchronized with the mold closing process, ensuring the stability and smoothness of the entire mold closing process and reducing the impact on the machine and mold. The inclined end face itself is an excellent guiding structure. Even if there is a very small residual deviation after the cone guide component 3 is corrected, causing the slider 402 and the locking block 401 to not be perfectly aligned, the inclined plane can still play a final fine-tuning guiding role, forcing the slider 402 to slide into the correct shrinkage path along the inclined plane, ensuring that the locking action can be completed smoothly in the end, and improving the fault tolerance and reliability of the entire positioning structure.

[0052] In this embodiment, the locking block 401 is provided with an insertion groove 404, which penetrates the end face of the locking block 401 and corresponds to the slider 402. The insertion groove 404 provides a dedicated space for the final locking of the slider 402. When the mold is closed, the slider 402 is precisely inserted into the insertion groove 404 under the action of spring force, forming a mechanical interlocking structure similar to a "pin" and a "hole".

[0053] This method of surface contact or large-area mating, compared to simple planar contact, can withstand greater and more complex loads, and the locking effect is extremely reliable and stable, completely eliminating the possibility of the mold loosening under injection pressure;

[0054] The insertion and engagement of the slot 404 and the slider 402 establishes a positive mechanical constraint between the locking block 401 and the slider 402. This structure can directly and effectively resist the huge mold expansion force generated during the injection molding process, and prevent any slight separation or misalignment between the fixed mold 1 and the moving mold 2 that could affect product quality. This ensures the stability of the mold cavity and provides a key guarantee for molding high-precision, flash-free products.

[0055] In this embodiment, the moving mold 2 is provided with a fixing groove 201, the shape of which is adapted to the locking block 401; the fixing groove 201 provides a dedicated receiving space for the locking block 401 on the fixed mold 1;

[0056] When the mold is closed, the locking block 401 can be perfectly embedded in the fixing groove 201. This design allows the locking component 4 to be completely integrated into the mold body after the mold is closed, avoiding the locking block 401 from forming a protrusion or overhang structure on the outside of the mold parting surface. This greatly optimizes the overall structure of the mold, makes the mold design more compact, and saves installation space.

[0057] Through the tight fit between the fixed groove 201 and the locking block 401, after mold closing, the locking block 401 and the moving mold 2 form a highly integrated mechanical structure. This not only effectively resists the mold expansion force caused by injection pressure, but also significantly enhances the overall rigidity and stability of the mold in the direction perpendicular to the mold opening and closing direction after mold closing, preventing the mold from undergoing slight displacement or vibration under lateral forces, thus providing a solid mechanical foundation for molding high-precision products.

[0058] In the final stage of mold closing, as the locking block 401 is guided into the fixing groove 201, its sidewalls come into contact with the inner wall of the fixing groove 201, providing auxiliary guidance. Working in conjunction with the conical guide assembly 3, this ensures the absolute accuracy of the final mold closing position. Simultaneously, enclosing the locking block 401 within the fixing groove 201 also protects it, reducing the risk of accidental impacts or damage in the production environment.

[0059] In this embodiment, the moving mold 2 is also provided with a sliding groove 202, which is located on the side of the fixed groove 201 and communicates with it. The slider 402 is slidably disposed within the sliding groove 202. The sliding groove 202 provides a dedicated, rigid guide track for the reciprocating motion of the slider 402, restricting the movement path of the slider 402 and ensuring that the slider 402 maintains a straight line motion throughout the entire process of compression retreat and ejection locking, without any deflection, jamming, or skewness. This is the fundamental guarantee for achieving precise insertion and engagement between the slider 402 and the locking block 401, greatly improving the repeatability and reliability of the locking action.

[0060] Setting the slide 202 on the side of the fixed groove 201 and communicating with it is a highly integrated design; it makes the two core components, the locking block 401 (embedded in the fixed groove 201) and the slider 402 (located in the slide 202) that drives its locking, closely adjacent in space and work together; this layout saves the most valuable space in the mold to the maximum extent, making the mold structure more compact and reasonable, and avoiding the problem of the mold becoming too bulky due to the addition of the locking function;

[0061] The slide groove 202 structure provides a large area of ​​support and guidance for the slider 402, evenly transferring the force on the slider 402 during operation to the moving mold 2 body, avoiding stress concentration. This not only improves the stability of the slider 402 during movement but also reduces wear on the slider 402 and its connecting parts, thereby extending the service life of the entire locking assembly 4. At the same time, the closed or semi-closed slide groove 202 can also prevent dust, oil, and other impurities from directly intruding into the moving parts to a certain extent, thus playing a protective role.

[0062] In this embodiment, the moving mold 2 is further provided with at least two storage slots 203. The two storage slots 203 are respectively located at the top and bottom of the slide 202 and are connected to the slide 202. The length of the storage slot 203 is less than that of the slide 202. A limiting block 405 is provided in the storage slot 203. One end of the limiting block 405 is slidably disposed in the storage slot 203, and the other end is connected to the slider 402. An elastic member 403 is disposed in the storage slot 203. One end of the elastic member 403 is connected to the limiting block 405, and the other end is connected to the inner wall of the storage slot 203.

[0063] By arranging the placement slot 203 perpendicular to the slide groove 202 and embedding the elastic element 403 and the limiting block 405 within it, a "three-dimensional" layout of the drive system in three-dimensional space is achieved. This design maximizes the saving of space in the horizontal direction of the mold, avoiding the problem of significantly increasing the mold base size due to the installation of springs and sliders 402, making the entire locking structure very compact and easy to integrate into molds of various specifications. This structure effectively converts the axial extension and retraction movement of the elastic element 403 into the horizontal linear movement of the slider 402 through the limiting block 405. As an intermediate transmission component, the limiting block 405 transmits the spring force evenly and stably to the slider 402, ensuring the linearity and smoothness of the slider 402's movement within the slide groove 202, avoiding possible jamming or tilting of the slider 402 due to uneven force, thereby ensuring high repeatability and reliability of the engagement with the locking block 401.

[0064] The independent storage slot 203 provides a protected, standard installation space for the elastic element 403 (such as a spring). This allows for easy selection and replacement of elastic elements 403 of different specifications (such as different spring coefficients) according to the required locking force, achieving adjustable and adaptable locking force. Simultaneously, this design simplifies the assembly process, facilitating daily maintenance, repair, and parts replacement. The elastic element 403 is housed within the closed or semi-closed storage slot 203, avoiding direct contact with the external environment and effectively preventing dust, oil, and other impurities from entering its working surface, reducing the possibility of wear and corrosion. Furthermore, the sliding guide of the limiting block 405 protects the elastic element 403 from undue forces such as bending or eccentric loading, significantly extending the service life of the entire locking assembly 4 and ensuring its long-term performance stability.

[0065] In this embodiment, the positioning cone 302 is provided on the fixed mold 1, and the positioning groove 301 is provided on the moving mold 2; the moving mold 2 is also provided with a through hole 204, one end of the through hole 204 is connected to the slide groove 202, and the other end penetrates the side of the moving mold 2, and a pull rod 205 is provided in the through hole 204, one end of the pull rod 205 is connected to the slider 402, and the other end of the pull rod 205 extends to the outside of the moving mold 2;

[0066] Setting the positioning cone 302 on the stationary fixed mold 1 and the positioning groove 301 on the moving mold 2 is a more reasonable layout. This arrangement can avoid the precision core guide component (positioning cone 302) from moving frequently with the moving mold 2, reducing the risk of wear or damage caused by vibration and impact. It also facilitates precise machining and adjustment on the fixed mold 1, which is beneficial to maintaining the guiding accuracy in the long term and improving the life of the cone surface assembly.

[0067] The design of the pull rod 205 is a highly practical improvement. When manual mold opening is required (such as for debugging, maintenance, or power failure), the operator can pull the pull rod 205 from outside the mold to force the slider 402 out of the insertion slot 404 of the locking block 401, thus achieving manual unlocking. This provides a safe and reliable non-powered backup mold opening method, which greatly facilitates mold maintenance and debugging, and avoids production interruptions or safety hazards caused by the inability to open the mold.

[0068] The end of the pull rod 205 extending to the outside of the moving mold 2 can serve as a visual status indicator.

[0069] By observing the position of the pull rod 205 (whether it is extended or retracted), operators can intuitively determine the state of the internal slider 402 (whether it is in the locked or unlocked position), facilitating a quick diagnosis of whether the mold locking mechanism is working properly. The structure of the pull rod 205 also facilitates the disassembly and assembly of the slider 402. When it is necessary to replace or repair the slider 402 and its internal springs and other components, the slider 402 can be kept in a compressed state by pulling outward and fixing the pull rod 205, thereby simplifying the disassembly and assembly process and reducing the difficulty and time consumption of maintenance work.
