Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an inclined slide mechanical linkage injection mold with an inclined top. Background Technology

[0002] Sliding elements and angled ejectors are common structures in injection molds. Sliding elements are mainly used to achieve lateral core pulling or parting actions of the plastic part during mold parting, solving the demolding problem of plastic parts with lateral holes, grooves, bosses, etc. Angled ejectors are usually used to handle undercut structures inside or outside the plastic part. When ejecting the product, the movement of the angled ejector disengages the undercut parts, allowing the product to be smoothly removed from the mold. For general injection molded products, the injection purpose can be achieved by simple sliding elements and angled ejectors using independent actions. Sliding elements and angled ejectors are basically driven by cylinders or hydraulic cylinders to perform this independent action. However, installing cylinders or hydraulic cylinders on the mold increases energy consumption and greatly increases the usable area of ​​the mold. When the mold is large, the installation of hydraulic cylinders can interfere with the installation of the mold on the injection molding machine, and in severe cases, it may even make the mold impossible to install. Especially for products with complex structures, when there are undercuts in the core-pulling mechanism, it is necessary to install angled ejectors at the slide position to solve the demolding problem of the undercuts. How to ensure that the slide and angled ejectors can move in tandem during mold parting and closing to achieve the injection molding purpose without causing mutual interference has always been a challenge. For example... Figures 1-2 The injection molded product shown has an arc-shaped back structure with multiple holes, slots, bosses, etc. Since the arc shape is unsuitable as a parting plane, the back of the product must be fitted with a slide block for core pulling. At position A on the back, there is an undercut, so an ejector pin is needed within the slide block core pulling structure. This type of design presents significant challenges to injection mold design and production. During mold parting and closing, the slide block and ejector pin need to move. The challenge lies in effectively linking them without interference to achieve orderly core pulling and unhooking without damaging the product. Therefore, we urgently need a mechanism that allows for the linkage between the slide block and ejector pin to drive their orderly movement to meet the requirements of mold parting and closing. This will have a positive impact on the design of injection molds for similar products in the future, providing a new direction for the design of injection molds with complex structures. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mechanically linked injection mold with an inclined top.

[0004] To achieve the above objectives, a sliding mechanical linkage injection mold with an inclined top includes an upper mold and a lower mold. The upper mold has an upper mold core, and the lower mold has a lower mold core. The upper mold core and the lower mold core enclose a mold cavity. The mold also includes a sliding mechanism for pulling the core from the mold cavity. The sliding mechanism includes a sliding component and a guide component that drives the sliding component away from the mold cavity. The guide component includes a guide block and at least two guide rods distributed on both sides of the guide block. The sliding component includes a slider that can cooperate with the guide component to slide downwards at an incline. The bottom of the slider has an inclined sliding slope. The guide rods and the sliding... The inclined planes have the same slope and slide through the slider. The upper end of the slider is provided with a main insert that cooperates with the upper mold core and the lower mold core to form a mold cavity. The lower surface of the slider is provided with an inwardly extending mounting groove. The mounting groove is provided with a slide bar that is arranged in the same direction as the slider and extends out of the lower end of the slider. The bottom of the slide bar is provided with a first inclined plane with the same slope as the sliding inclined plane. The guide block is provided with a horizontally arranged transition surface and a second inclined plane that matches the slope of the first inclined plane. The top of the slide bar is connected to an inclined top that extends into the mold cavity through the main insert. The top of the slide bar is provided with an inclined top groove. The lower end of the inclined top is slidably connected to the inclined top groove.

[0005] The slider, guided by a guide rod, slides along a sliding ramp to demold the main insert and pull the core. An installation slot is created inside the slider to mount a slide bar, which in turn drives the inclined ejector for core pulling. This design requires consideration of whether the slider and slide bar demold and pull the core simultaneously. When the core pulling actions of the main insert and the inclined ejector have a sequential order, a problem arises. The slide bar is located inside the slider, and it moves synchronously with the slider, but the core pulling actions driven by both must have a specific sequence. Therefore, a guide block is placed at the bottom of the slide bar to cooperate with it. The guide block has a horizontally arranged transition surface and a second inclined surface. During mold parting, the slider slides downwards along the sliding ramp. Because the transition surface is horizontal, the slide bar is supported by the transition surface during this stage and will not move downwards, thus preventing the slider and slide bar from moving downwards simultaneously. When the slide bar engages with the second inclined surface, it will begin to slide downwards under the guidance of the second inclined surface, driving the inclined ejector to demold. However, the inclined ejector is designed to address undercuts; direct downward movement would damage the product. Therefore, we need the inclined ejector to also have lateral movement to move away from the undercut position of the product. Therefore, a sloping ejector groove is set at the top of the slide bar, and the lower end of the sloping ejector is slidably connected to the sloping ejector groove. As the slide bar moves downwards, the upper part of the sloping ejector experiences resistance from the main insert, causing the slide bar to pull the lower end of the sloping ejector to slide within the sloping ejector groove, driving the sloping ejector to move laterally simultaneously, thus achieving demolding. This effectively solves the problem of using sloping ejectors within the slide block for step-by-step demolding without interference. Furthermore, the driving force of the slider and slide bar comes from gravity, and the guiding force during mold parting can achieve the demolding and core-pulling action, eliminating the need for external driving components such as hydraulic cylinders. This not only provides good energy efficiency but also saves mold space. This structure adopts mechanical linkage demolding during mold parting, completing the step-by-step demolding and core-pulling action through mechanical movement without interference, offering strong practicality and further reducing manufacturing costs.

[0006] Preferably, the mounting groove is provided with an ejector assembly, which includes upper and lower corresponding fixing plates and a top plate. The fixing plate is provided with a plurality of parallel ejector pins that penetrate the main insert. The fixing plate is fixedly connected to the top of the slide bar and the fixing plate is fixedly connected to the top plate.

[0007] During mold parting, the slider and the angled ejector are demolded in stages, but the upper mold core and the lower mold core begin demolding of the product during mold parting. The product cannot rely solely on the angled ejector for support, so ejector pins are needed to support the product. A fixed plate with ejector pins is fixed to the slider. In the first stage of mold parting, the slider remains horizontal and does not move downwards. The slider drives the main insert to demold. At this time, as the main insert moves downwards, the ejector pins will push out the main insert, helping it to demold.

[0008] Preferably, the fixing plate is provided with at least two springs connected to the bottom of the main insert, and the springs are arranged in a rectangular array or a ring array.

[0009] The spring can buffer the ejection action of the ejector pin when the distance between the main insert and the fixed plate shortens. During the movement of the main insert and the fixed plate to restore the original distance, the elastic potential energy of the spring can assist the fixed plate to reset. Moreover, the process of the fixed plate resetting is the process of the first inclined surface of the slider adhering to the second inclined surface of the guide block. The spring can press the guide block down to drive the first inclined surface and the second inclined surface to fit tightly together.

[0010] Preferably, the bottom of the slider is provided with a sealing block for sealing the mounting groove, the sealing block is provided with two symmetrically arranged guide posts parallel to the ejector pin, the fixing plate and the top plate are provided with guide sleeves that match the guide posts, and the bottom of the top plate is provided with multiple elastic pads.

[0011] The guide post and guide sleeve work together to guide the movement of the fixed plate and top plate, ensuring smooth movement. The elastic pad prevents the top plate from directly impacting the encapsulation block when the fixed plate and top plate are reset.

[0012] Preferably, the encapsulation block is provided with at least two positioning posts, and the other end of the positioning posts extends to the bottom of the mounting groove.

[0013] The positioning pins limit the depth to which the package block extends into the mounting slot, ensuring the accuracy of the package block's installation position.

[0014] Preferably, the encapsulation block is provided with a third inclined surface with the same slope as the sliding inclined surface, and the third inclined surface and the sliding inclined surface are on the same plane.

[0015] Ensure that the encapsulation block does not interfere with the slider during sliding.

[0016] Preferably, the lower end of the slide bar is provided with a horizontally arranged sliding surface that fits against the transition surface, and the side surface, the first inclined surface, and the sliding surface of the slide bar are all provided with a first shallow groove for material sliding.

[0017] Setting a sliding surface allows the slider to better fit the transition surface, resulting in smoother sliding. The sliding of the slider will generate friction, which requires the application of lubricating grease in the mold industry to help the slider slide. Since the mold needs to ensure high precision, the sliding friction surfaces are generally tightly fitted. Setting a first shallow groove can store lubricating grease, ensuring the lubrication effect and preventing the lubricating grease from being consumed too quickly.

[0018] Preferably, the demolding movement direction of the slider forms an acute angle with the vertical line, which is an inclined demolding direction. The slider is provided with a demolding guide slope with the same slope as the demolding movement direction of the slider. The upper mold is provided with a guide surface corresponding to the demolding guide slope. The upper mold is provided with a sliding groove. The slider is provided with sliding protrusions on both sides that match the sliding groove. The guide block and the end of the guide rod are both fixed to the lower mold.

[0019] When the sliding component is tilted and the slider does not move directly downwards to demold, we set a demolding guide slope with the same slope as the slider's demolding movement direction, and also set a guide surface corresponding to the demolding guide slope. Through the cooperation of the demolding guide slope and the guide surface, we ensure that the slider can tilt and move in a predetermined direction to demold.

[0020] Preferably, the guide surface is provided with guide protrusions of the same slope along its length direction, the demolding guide slope is provided with guide grooves that match the guide protrusions, and the demolding guide slope is provided with limit posts, the guide surface is provided with limit grooves that match the limit posts and are parallel to the guide protrusions, and the guide surface is also provided with tiger buckles, the clamping end of the tiger buckles being connected to the limit grooves.

[0021] The combination of the guide ridge and the guide groove can further improve the guiding effect on the slider when it tilts. The combination of the limit post and the tiger buckle can limit the stroke of the slider when it tilts, and prevent the slider from excessively disengaging from the upper mold, which is not conducive to subsequent mold closing.

[0022] Preferably, the lower mold is provided with a fourth inclined surface corresponding to the sliding inclined surface, and wear-resistant plates are provided on both sides of the slider, the fourth inclined surface, and the guide surface. A second shallow groove for material sliding is provided on the outward side of the wear-resistant plate.

[0023] The materials used for mold blanks are generally soft, and long-term friction can easily cause wear or even sintering. Therefore, wear-resistant plates need to be set on the friction surface of the slider to support the friction. A second shallow groove for the slider can be set to store lubricating grease to ensure the lubrication effect and prevent the lubricating grease from being consumed too quickly.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This invention guides the slider by setting a guide rod, and a slide bar is set on the slider. A guide block is set at the bottom of the slide bar to cooperate with it. The guide block has a horizontally arranged transition surface and a second inclined surface. During mold parting, the slider slides down along the sliding inclined surface. Since the transition surface is horizontal, the slide bar is supported by the transition surface at this stage and will not move down, thus separating the slider and the slide bar from moving down at the same time. When the slide bar cooperates with the second inclined surface, the slide bar will start to slide down under the guidance of the second inclined surface, driving the inclined ejector to demold, thus realizing the step-by-step demolding action of the slider and the slide bar.

[0026] An inclined top groove is provided at the top of the slide bar. The lower end of the inclined top is slidably connected to the inclined top groove. As the slide bar moves downward, the upper part of the inclined top is subjected to a certain resistance from the main insert. The slide bar will pull the lower end of the inclined top to slide in the inclined top groove, driving the inclined top to make a lateral movement at the same time, so as to achieve the demolding of the inclined top.

[0027] This design effectively solves the problem of using angled ejectors within the mold slide for step-by-step demolding without interference. Furthermore, the driving force for the sliders and slide bars comes from gravity, and the guiding action during mold parting achieves the demolding and core-pulling action directly, eliminating the need for external driving components such as hydraulic cylinders. This not only results in good energy efficiency but also saves mold space. This structure employs mechanical linkage demolding during mold parting, completing the step-by-step demolding and core-pulling actions through mechanical movement without interference. It is highly practical and further reduces manufacturing costs. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0045] In injection molding, injection molding machines are generally horizontal. The injection mold is placed horizontally, with the lower mold fixed to the mounting plate on the left side of the injection molding machine. The sprue of the upper mold is aligned with the injection port on the right side of the injection molding machine. The mold opens and closes by moving the right side of the injection molding machine.

[0046] This utility model provides a slanted slide mechanical linkage injection mold with a slanted top, such as... Figures 3-15 As shown, it includes an upper mold 1 and a lower mold 2. The upper mold 1 is provided with an upper mold core 3, and the lower mold 2 is provided with a lower mold core 4. The upper mold core 3 and the lower mold core 4 enclose a mold cavity. It also includes a sliding mechanism 5 for pulling the core out of the mold cavity.

[0047] The sliding mechanism 5 includes a sliding component 6 and a guide component 7 that drives the sliding component 6 away from the mold cavity. The guide component 7 includes a guide block 8 and at least two guide rods 9 distributed on both sides of the guide block 8. The ends of the guide block 8 and the guide rods 9 are fixed to the lower mold 2, and the other ends extend to the upper mold 1. The sliding component 6 includes a slider 10 that can cooperate with the guide component 7 to slide downward at an angle. The bottom of the slider 10 is provided with a downwardly inclined sliding slope 11. The upper mold 1 is provided with a sliding groove 12. The sides of the slider 10 are provided with sliding protrusions 13 that match the sliding groove 12. The slider 10 can slide along the sliding groove 12 on the upper mold 1. The guide rod 9 has the same slope as the sliding ramp 11 and slides through the slider 10. During mold parting, the slider 10 slides downward with the sliding ramp 11 as the guide. The guide rod 9 plays an auxiliary and guiding role for the slider 10, making the sliding action smooth. During mold closing, the guide rod 9 plays a guiding role for the slider 10, driving the slider 10 to return to its original position along the guide rod 9.

[0048] The demolding movement direction of the slider 10 forms an acute angle with the vertical line, which is an inclined demolding direction. The slider 10 is provided with a demolding guide slope 14 with the same slope as the demolding movement direction of the slider 10. The upper mold 1 is provided with a guide surface 15 corresponding to the demolding guide slope 14. To ensure that the product is demolded and reset along the predetermined slope direction, the demolding guide slope 14 is provided to cooperate with the guide surface 15 of the upper mold 1 to guide the demolding sliding of the slider 10. The slider 10 cooperates with the lower mold 2 to drive the slider 10 to slide downward. The slider 10 cooperates with the upper mold 1 to drive the slider 10 to demold and pull the core along the predetermined slope when sliding down. The upper mold 1 is provided with a stepped surface 16 with the same slope as the guide surface 15 above the guide surface 15. The stepped surface 16 is screwed to fix a sliding strip 17. The part of the sliding strip 17 extending out of the guide surface 15 forms a sliding groove 12 between the sliding strip 17 and the guide surface 15.

[0049] The upper end of the slider 10 is provided with a main insert 18 that cooperates with the upper mold core 3 and the lower mold core 4 to form a mold cavity. The lower surface of the slider 10 is provided with an inwardly extending mounting groove 19. The slider is fixedly connected to the main insert 18 by screws passing through the bottom of the mounting groove 19. The mounting groove 16 is provided with a slide bar 20 that is arranged in the same direction as the slider 10 and extends out of the lower end of the slider 10. The bottom of the slide bar 20 is provided with a first inclined surface 21 with the same slope as the sliding inclined surface 11. The guide block 8 is provided with a horizontally arranged transition surface 22 and a second inclined surface 23 that matches the slope of the first inclined surface 21. The lower end of the slide bar 20 is provided with a horizontally arranged sliding surface 24 that fits against the transition surface 22. When the slider 10 slides downwards during mold parting, in the first stage, the sliding surface 24 of the slider 20 slides in contact with the transition surface 22 of the guide block 8. During this stage, the slider 20 does not undergo any height displacement. The slider 10 drives the main insert 18 to demold first. In the second stage of mold parting, when the first inclined surface 21 of the slider 20 is in contact with the second inclined surface 23 of the guide block 8, the slider 20 slides downwards along the second inclined surface 23 as the mold parting action occurs. The top of the slider 20 is connected to an inclined top 25. The inclined top 25 passes through the main insert 18 and its upper end extends into the mold cavity. The upper end of the inclined top 25 is provided with an undercut protrusion 26 extending to the left. The top of the slider 20 is provided with an inclined top groove 27, and the lower end of the inclined top 25 is slidably connected to the inclined top groove 27. The length direction of the inclined ejector 25 forms an angle with the length direction of the slide bar 20. In the mold-closed state, the lower end of the inclined ejector 25 is located on the left side of the inclined ejector groove 27. During mold opening, the slide bar 20 moves downwards, causing the inclined ejector 25 to slide to the right along the inclined ejector groove 27, thus demolding the inclined ejector 25 and disengaging the undercut protrusion 26 from its snap-fit ​​position on the product. The inclined ejector groove 27 is an inverted T-shape, and the lower end of the inclined ejector 25 is a T-shape that matches the inclined ejector groove 27. The sides, first inclined surface 21, and sliding surface 24 of the slide bar 20 are all provided with first shallow sliding grooves 28. When in use, the sides and bottom of the slide bar 20 need to be coated with lubricating grease to reduce friction between the slide bar 20 and other components. The first shallow sliding grooves 28 can hold the lubricating grease, preventing it from being consumed too quickly.

[0050] An ejector assembly is provided in the mounting groove 19. The ejector assembly includes a fixed plate 29 and a top plate 30 with corresponding upper and lower parts. The fixed plate 29 and the top plate 30 are fixedly connected by screws. The fixed plate 29 is provided with a plurality of parallel ejector pins 31 that penetrate the main insert 18. The pins of the ejector pins 31 are fixed to the fixed plate 29. The fixing method between the ejector pins 31 and the fixed plate 29 can be implemented by any existing technology. The upper surface of the ejector pins 31 and the surface of the corresponding position of the main insert 18 are on the same plane. The fixed plate 29 is fixedly connected to the top of the slide bar 20. In the first stage of mold parting, the slide bar 20 supports the fixed plate 29 and does not move downward. At this time, the ejector pins 31 and the inclined ejector 25 jointly support the product. In the second stage of mold parting, the slide bar 20 drives the fixed plate 29 to move downward, and the ejector pins 31 are separated from the product. The fixing plate 29 is provided with at least two springs 32 connected to the bottom of the main insert 18. During the first stage of mold separation, the main insert 18 begins to demold, while the fixing plate 29 maintains a constant height. The distance between the main insert 18 and the fixing plate 29 continuously shortens. The function of the springs 32 is to buffer the relative movement between the two. During the second stage of mold separation, the springs 32 begin to reset and, relying on their elastic potential energy, further press the slide bar 20 against the guide block 8 to reduce the vibration of the slide bar 20. The springs 32 are arranged in a rectangular array or a ring array to ensure the uniformity of the force between them and the fixing plate 29. The bottom of the slider 10 is provided with a sealing block 33 that encapsulates the opening of the mounting groove 19. The sealing block 33 is fixedly connected to the slider 10 by screws. The sealing block 33 is provided with two symmetrically arranged guide posts 34 parallel to the ejector pin 31. The lower end of the guide posts 34 is fixedly connected to the sealing block 33 by screws. The fixing plate 29 and the top plate 30 are provided with guide sleeves 35 that match the guide posts 34. Through the cooperation of the guide posts 34 and the guide sleeves 35, the fixing plate 29 and the top plate 30 can be guided by the guide posts 34 when moving in the mounting groove 19. Combined with the spring 32, the fixing plate 29 is subjected to uniform force, so that the fixing plate 29 and the top plate 30 can move smoothly without deviation. In the second stage of mold parting, the top plate 30 gradually moves towards the sealing block 33 until it contacts it. The bottom of the top plate 30 is provided with multiple elastic pads 35 to buffer when the top plate 30 reaches the sealing block 33 and prevent the top plate 30 from directly impacting the sealing block 33.

[0051] The encapsulation block 33 is provided with at least two positioning posts 36, which are fixedly connected to the encapsulation block 33 by screws. The other end of the positioning post 36 extends to the bottom of the mounting groove 19. The positioning post 36 is used to limit the depth of the encapsulation block 33 into the mounting groove 19, ensuring the accuracy of the installation position of the encapsulation block 33. The encapsulation block 33 is provided with a third inclined surface 37 with the same slope as the sliding inclined surface 11. The third inclined surface 37 and the sliding inclined surface 11 are on the same plane, ensuring that the slider 10 can slide normally.

[0052] The upper mold 1 has guide surfaces 15 with guide protrusions 38 of the same slope along its length. The demolding guide slope 14 of the slider 10 has guide grooves 39 that match the guide protrusions 38 to prevent the slider 10 from deviating during sliding. A limiting post 40 is provided on the demolding guide slope 14, with one end of the limiting post 40 embedded in and fixedly connected to the slider 10. The limiting post 40 is perpendicular to the demolding guide slope 14. The upper mold 15 is provided with a limiting groove 41 that matches the limiting post 40 and is parallel to the guide slide protrusion 38. When the slider 10 slides, the other end of the limiting post 40 extends into the limiting groove 41 and slides synchronously along the limiting groove 41. The guide slide surface 15 is also provided with a tiger buckle 42. The tiger buckle 42 is fixedly connected and embedded in the upper mold 1 by screws. After installation, the guide slide surface 15 does not have a protruding part due to the tiger buckle 42. The clamping end of the tiger buckle 42 is connected to the limiting groove 41. When the mold is separated, the slider 10 stops sliding when the limiting post 40 falls into the tiger buckle 42 and is engaged. This controls the stroke of the slider 10 and prevents the slider 10 from completely leaving the upper mold 1. The tiger buckle 42 can be implemented by any technology, which needs to meet the requirements that the limiting post 40 can be engaged when entering the tiger buckle 42 and can be disengaged normally when the limiting post 40 is disengaged from the tiger buckle 42 in the opposite direction.

[0053] The lower mold 2 is provided with a fourth inclined surface 43 corresponding to the sliding inclined surface 11. The fourth inclined surface 43 guides the slider 10. Wear-resistant plates 44 are provided on both sides of the slider 10, the fourth inclined surface 43 of the lower mold 2, and the guide surface 15 of the upper mold 1. The wear-resistant plates 44 are fixed to the target object by screws. Considering that the hardness of the mold blank material is not high and it is easy to wear and sinter due to long-term friction, the hardness and wear resistance of the wear-resistant plates 44 are better than those of the materials of the upper mold 1 and the lower mold 2. The wear-resistant plates 44 protect the body of the upper mold 1 and the lower mold 2 through friction. A second sliding shallow groove 45 is provided on the outward side of the wear-resistant plate 44. When in use, lubricating grease is applied to the wear-resistant plate 44. The second sliding shallow groove 45 is used to store the lubricating grease and prevent the lubricating grease from being consumed too quickly. The first sliding shallow groove 28 and the second sliding shallow groove 45 are groove textures provided on the target object. The texture can be a single shape or combination of stripes, arcs, circles, rectangles and other shapes.

[0054] The upper mold 1 is provided with a plurality of upper positioning blocks 46, and the lower mold 2 is provided with a plurality of lower positioning blocks 47 respectively corresponding to the upper positioning blocks 46. The upper positioning blocks 46 are provided with positioning protrusions extending downward to the lower mold 2, and the lower positioning blocks 47 are provided with positioning grooves corresponding to the positioning protrusions 46.

[0055] Working principle:

[0056] The product is injection molded in the mold-closed state. After injection molding, mold separation begins. In the first stage of mold separation, the upper mold core 3 and the lower mold core 4 begin to separate and demold. The slider 10 and the lower mold 2 gradually separate downwards through the contact of the sliding inclined surface 11 and the fourth inclined surface 43, and the guidance of the guide rod 9. The slider 10 drives the main insert 18 to demold and slide downwards. At the same time, the slider 10 and the upper mold 1 separate through the contact of the demolding guide inclined surface 14 and the guide surface 15, and the cooperation of the sliding protrusion 13 and the sliding groove 12. With the cooperation of the guide rib 38 and the guide groove 39, the slider 10 slides downward at a predetermined angle. During this stage, the sliding surface 24 at the lower end of the slider 20 slides horizontally against the transition surface 22 of the guide block 8. The slider 20, along with the inclined ejector 25, the fixed plate 29, and the ejector pin 31, remains horizontal and does not move downward. The main insert 18 gradually moves downward towards the fixed plate 29 under the action of the slider 10, shortening the distance between the two. The first stage of mold separation is completed, with only the ejector pin 31 and the inclined ejector 25 supporting the product. In the second stage of mold parting, as the mold parting action continues, the first inclined surface 21 of the slide bar 20 begins to engage with the second inclined surface 23 of the guide block 8. The slide bar 20 gradually slides downward, causing the fixed plate 29 and ejector pin 31 to slide downward and disassemble. The distance between the fixed plate 29 and the main insert 18 gradually returns to its original spacing. Simultaneously, due to the downward sliding of the slide bar 20, the inclined ejector pin 25 is driven to slide to the right along the inclined ejector pin groove 27. The undercut protrusion 26 at the upper end of the inclined ejector pin 25 gradually separates from the product. The slider 10 continues to slide with the upper mold 1 and the lower mold 2, maintaining the sliding mode and track of the first stage. When it reaches the end of its stroke, the limit post 40 engages with the tiger buckle 42, and the slider 10 stops sliding, completing the mold parting. During mold closing, the slider 10 and the lower mold 2 are guided by the guide rod 9, causing the slider 10 to slide upward and reset. At the same time, the limit post 40 disengages from the tiger buckle 42 between the slider 10 and the upper mold 1, and the slider 10 slides upward and resets.
