Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an inclined sliding position mechanical linkage injection mold with an inclined top. Background Art

[0002] Sliders and lifters are commonly used structures in injection molds. Sliders are mainly used to realize the lateral core pulling or parting action of the plastic part during the mold separation process, so as to solve the demolding problem of the plastic part with lateral holes, grooves, bosses and other structures. The lifter is usually used to deal with the undercut structure inside or outside the plastic part. When ejecting the product, the undercut part is dislodged by the movement of the lifter, so that the product can be smoothly removed from the mold. For general injection molded products, the injection purpose can be achieved mainly through the independent action of simple slides and lifters. The slides and lifters are basically driven by cylinders or oil cylinders to perform this independent action. In addition, installing cylinders or oil cylinders on the mold will increase energy consumption and greatly increase the usable area of the mold. When the mold is large, the installed oil cylinder setting will 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 is an undercut in the core pulling position of the slide, it is necessary to install a lifter at the slide position to solve the demoulding problem of the undercut. How to realize the linkage between the slide and lifter to achieve the purpose of injection molding without mutual interference during mold separation and closing has always been a difficult problem. Figure 1-Figure 2 The injection molded product shown has an arc-shaped structure on the back, and has multiple holes, grooves, bosses and other structures. Since the arc shape is not suitable as a reference plane for mold parting, the back of the injection molded product can only be equipped with a slide for core pulling. At position A on the back, we can see that there is an inverted position, so we also need to set a lifter inside the slide core pulling structure. This type of structure poses great difficulties to the design and production of injection molds. During the mold parting and closing process, the slide and the lifter need to move. How to effectively link the two without interfering with each other to achieve the purpose of orderly core pulling and releasing without damaging the product. Therefore, we urgently need a slide and lifter that can be linked to drive the orderly movement between the two to complete the requirements of mold parting and closing. This will have a good impact on the future design of injection molds for similar products in this field and provide a new direction for the design of injection molds with complex structures. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an inclined sliding position mechanical linkage injection mold with an inclined top.

[0004] In order to achieve the above purpose, a mechanically linked injection mold with an inclined top and an inclined slide comprises an upper mold and a lower mold, the upper mold is provided with an upper mold core, the lower mold is provided with a lower mold core, the upper mold core and the lower mold core enclose a mold cavity, and also comprises a slide mechanism for core pulling of the mold cavity, the slide structure comprises a slide assembly and a guide assembly for driving the slide assembly away from the mold cavity, the guide assembly comprises a guide block and at least two guide rods distributed on both sides of the guide block, the slide assembly comprises a slider that can cooperate with the guide assembly to slide obliquely downward, the bottom of the slider is provided with a sliding inclined surface inclined downward, the guide rod and the slide The inclined surfaces 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 installation groove. A slide bar is provided in the installation groove and 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 surface with the same slope as the sliding inclined surface. The guide block is provided with a horizontally arranged transition surface and a second inclined surface matching the slope of the first inclined surface. The top of the slide bar is connected to an inclined top whose upper end passes through the main insert and extends into the mold cavity. The top of the slide bar is provided with an inclined top slide groove, and the lower end of the inclined top is slidably connected to the inclined top slide groove.

[0005] The slider, guided by a guide rod, slides along a ramp to eject the main insert from the mold. A mounting slot is provided within the slider to accommodate a slider, which drives the lifter for core pulling. This setup requires consideration of whether the slider and slider can be ejected and pulled simultaneously. This presents a challenge when the core pulling of the main insert and the lifter must occur in a sequential order. The slider, located within the slider, moves synchronously with the slider, while the core pulling actions driven by both must also be prioritized. Therefore, a guide block is placed at the bottom of the slider to cooperate with it. The guide block features a horizontal transition surface and a second ramp. During mold release, the slider slides downward along the ramp. Because the transition surface is horizontal, the slider is supported by the transition surface and prevents downward movement, thus preventing simultaneous downward movement of the slider and bar. When the slider engages the second ramp, it begins to slide downward, guided by the second ramp, ejecting the lifter. However, the lifter is designed to address undercuts. Direct downward movement would damage the product. We need the lifter to also have lateral movement to remove the undercut. Therefore, a sloping top slot is provided at the top of the slide bar, and the lower end of the sloping top is slidably connected to the sloping top slot. When the slide bar moves downward, the upper part of the sloping top is subject to a certain resistance from the main insert, and the slide bar will pull the lower end of the sloping top to slide in the sloping top slot, driving the sloping top to move sideways at the same time, thereby realizing demoulding of the sloping top. This effectively solves the problem of setting a sloping top in the row position for step-by-step demoulding without interference, and the driving force of the slider and the slide bar comes from gravity. The guide during mold parting can realize the demoulding and core pulling action without the use of external driving objects such as oil cylinders. It not only has a good energy-saving effect, but also saves the use space of the mold. This structure adopts mechanical linkage demoulding during mold parting, and completes the step-by-step demoulding and core pulling action through mechanical action without interference. It is highly practical and saves manufacturing costs.

[0006] Preferably, an ejection assembly is provided in the mounting groove, and the ejection assembly includes a fixed plate and a top plate corresponding to the upper and lower parts. The fixed plate is provided with a plurality of ejector pins arranged in parallel and passing through the main insert. The fixed plate is fixedly connected to the top of the slide bar, and the fixed plate is fixedly connected to the top plate.

[0007] During mold separation, the slider and inclined ejector are used for separate demolding. However, the upper and lower mold cores begin to release the product during mold separation. The product cannot rely solely on the inclined ejector for support, so ejector pins are required to support the product. A fixed plate with ejector pins is fixed to the slider. During the first stage of mold separation, the slider remains horizontal and does not move downward. The slider drives the main insert to be demolded. At this time, as the main insert moves downward, the ejector pins will push out the main insert, helping to release it from the mold.

[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 an annular array.

[0009] The spring can buffer the ejection action of the ejector when the distance between the main insert and the fixed plate is shortened. In the process of the main insert and the fixed plate recovering their original distance, the elastic potential energy of the spring reset can assist the fixed plate in resetting. Moreover, the process of the fixed plate resetting is exactly the process of the first inclined surface of the slide bar fitting the second inclined surface of the guide block. The spring can press the guide block downward to drive the first inclined surface and the second inclined surface to fit tightly.

[0010] Preferably, a packaging block is provided at the bottom of the slider to encapsulate the mounting slot, and the packaging block is provided with two guide pillars arranged symmetrically and parallel to the ejector pins. Guide sleeves matching the guide pillars are provided on the fixed plate and the top plate, and a plurality of elastic pads are provided at the bottom of the top plate.

[0011] The cooperation of the guide pin and the guide sleeve guides the movement of the fixed plate and the top plate to ensure smooth movement. The function of the elastic pad is to prevent the top plate from directly hitting the packaging block when the fixed plate and the top plate are reset.

[0012] Preferably, at least two positioning posts are provided on the packaging block, and the other ends of the positioning posts extend to the bottom of the mounting groove.

[0013] The depth of the package block extending into the installation groove is limited by the positioning column to ensure the accuracy of the installation position of the package block.

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

[0015] Make sure that the package block does not interfere when the slider slides.

[0016] Preferably, a sliding surface arranged horizontally and in contact with the transition surface is provided at the lower end of the slide bar, and a first sliding material shallow groove is provided on the side surface, the first inclined surface and the sliding surface of the slide bar.

[0017] Setting a sliding surface can make the slider fit the transition surface better and slide more smoothly. The sliding of the slider will generate friction, which requires the application of lubricating grease in the mold field to help the slider slide. Since the mold needs to ensure high precision, the sliding friction surfaces are generally tightly fitted. Setting the first sliding material shallow groove can store lubricating grease, ensure the lubrication effect, and avoid excessive consumption of lubricating grease.

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

[0019] When the sliding assembly is set at an angle and the slider does not move directly downward for demoulding, we set a demoulding guide slope with the same slope as the demoulding movement direction of the slider, and also set a guide sliding surface corresponding to the demoulding guide slope. Through the cooperation of the demoulding guide slope and the guide sliding surface, it is ensured that the slider can be moved in a predetermined direction for demoulding.

[0020] Preferably, the guide sliding surface is provided with a guide sliding protrusion with a consistent slope along its length direction, the demoulding guide inclined surface is provided with a guide sliding groove matching the guide sliding protrusion, and a limiting column is provided on the demoulding guide inclined surface, the guide sliding surface is provided with a limiting groove matching the limiting column and parallel to the guide sliding protrusion, and the guide sliding surface is also provided with a tiger buckle, and the clamping end of the tiger buckle is connected to the limiting groove.

[0021] The cooperation between the guide slide ridge and the guide slide groove can further improve the guiding effect of the slider during tilting movement. The cooperation between the limit column and the tiger buckle can limit the tilting sliding stroke of the slider, preventing the slider from excessively disengaging from the upper mold, which is not conducive to subsequent mold closing.

[0022] Preferably, the lower die is provided with a fourth inclined surface corresponding to the sliding inclined surface, and the two side surfaces of the slider, the fourth inclined surface and the guide sliding surface are all provided with wear-resistant sheets, and the wear-resistant sheet is provided with a second sliding shallow groove on the outward side.

[0023] The material used for the mold base is generally soft and prone to wear or even sintering due to long-term friction. Therefore, a wear-resistant sheet needs to be set on the friction surface of the slider to support friction. A second sliding shallow groove can be set to store lubricating grease to ensure lubrication effect and avoid excessive consumption of lubricating grease.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention guides the sliding of the slider by setting a guide rod, a sliding bar is set on the slider, and a guide block is set at the bottom of the sliding bar to cooperate with it. The guide block is provided with a horizontally arranged transition surface and a second inclined surface. When the mold is separated, the slider slides downward along the sliding inclined surface. Since the transition surface is horizontally arranged, the slide is supported by the transition surface and will not move downward at this stage, thereby separating the movement of the slider and the slide bar moving downward at the same time; when the slide bar cooperates with the second inclined surface, the slide bar will start to slide downward under the guidance of the second inclined surface, driving the inclined top to demould, thereby realizing the step-by-step demoulding action of the slider and the slide bar.

[0026] A sloped top chute is set at the top of the slide bar, and the lower end of the sloped top is slidably connected to the sloped top chute. When the slide bar moves downward, the upper part of the sloped top is subject to a certain resistance from the main insert. The slide bar will pull the lower end of the sloped top to slide in the sloped top chute, driving the sloped top to move sideways at the same time to achieve sloped top demoulding.

[0027] This effectively solves the problem of installing a ramp within the slide for step-by-step demoulding without interference. Furthermore, the driving force for the slider and the slide bar is gravity, and the guide during mold parting can achieve demoulding and core pulling, eliminating the need for external drivers such as hydraulic cylinders. This not only provides excellent energy savings but also saves mold space. This structure utilizes mechanical linkage demoulding during mold parting, completing the step-by-step demoulding and core pulling through mechanical action without interference, resulting in high practicality and even lower manufacturing costs.

[0044] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0045] During injection molding, the injection molding machine is basically a horizontal injection molding machine. The injection mold is placed horizontally, the lower mold is fixed on the mounting plate on the left side of the injection molding machine, the pouring port of the upper mold is aligned with the injection port on the right side of the injection molding machine, and the mold is opened and closed by moving the right side of the injection molding machine.

[0046] The present invention provides a mechanically linked injection mold with an inclined top and an inclined position. Figure 3-Figure 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, 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, and also includes a sliding mechanism 5 for core pulling of the mold cavity.

[0047] The slide structure 5 includes a slide assembly 6 and a guide assembly 7 that drives the slide assembly 6 away from the mold cavity. The guide assembly 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 toward the upper mold 1. The slide assembly 6 includes a slider 10 that can cooperate with the guide assembly 7 to slide downward at an angle. The bottom of the slider 10 is provided with a downward-sloping sliding slope 11. The upper mold 1 is provided with a slide groove 12. The slider 10 is provided with sliding protrusions 13 on both sides that match the slide groove 12. The slider 10 can slide on the upper mold 1 along the slide groove 12. The guide rod 9 has the same inclination as the sliding slope 11 and slides through the slider 10. When the mold is separated, the slider 10 slides downward with the sliding slope 11 as the guide. The guide rod 9 assists and guides the slider 10 to make the sliding action smooth. When the mold is closed, the guide rod 9 guides the slider 10, driving the slider 10 to return to its original position upward along the guide rod 9 so as not to deviate from its original position.

[0048] The demoulding direction of the slider 10 forms an acute angle with the vertical line, which is an inclined demoulding direction. The slider 10 is provided with a demoulding guide bevel 14 with the same slope as the demoulding direction of the slider 10, and the upper mold 1 is provided with a guide sliding surface 15 corresponding to the demoulding guide bevel 14. To ensure that the product is demoulded and reset along the predetermined slope, the demoulding guide bevel 14 is provided to cooperate with the guide sliding surface 15 of the upper mold 1 to guide the demoulding sliding of the slider 10. The slider 10 cooperates with the lower mold 2 to drive the slider 10 to slide downward, and the slider 10 cooperates with the upper mold 1 to drive the slider 10 to demould and core out along the predetermined slope when sliding down. The upper mold 1 is provided with a step surface 16 with the same slope as the guide sliding surface 15 above the guide sliding surface 15. The step surface 16 is screwed with a sliding bar 17. The sliding bar 17 extends out of the guide sliding surface 15 and forms a sliding groove 12 with the guide sliding 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 the 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 from 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 with a matching 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 is in contact with the transition surface 22. During mold separation, when the slider 10 slides downward, the sliding surface 24 of the slider 20 slides in contact with the transition surface 22 of the guide block 8 in the first stage. During this stage, the slider 20 does not move in height, and the slider 10 drives the main insert 18 to be demolded first. In the second stage of mold separation, 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 downward along the second inclined surface 23 as the mold is separated. The top of the slider 20 is connected to a slanted top 25, which passes through the main insert 18 and extends into the mold cavity at its upper end. The upper end of the slanted top 25 is provided with an undercut protrusion 26 extending to the left. The top of the slider 20 is provided with a slanted top groove 27, and the lower end of the slanted top 25 is slidably connected to the slanted top groove 27. The length of the slanted top 25 forms an angle with the length of the slide 20. In the closed mold state, the lower end of the slanted top 25 is located to the left of the slanted top chute 27. During mold separation, the slide 20 moves downward, driving the slanted top 25 to slide rightward along the slanted top chute 27, thereby releasing the slanted top 25 from the mold and removing the undercut protrusion 26 from the buckle position on the product. The slanted top chute 27 is in an inverted T-shape, and the lower end of the slanted top 25 is in a T-shape that matches the slanted top chute 27. The side surface, first inclined surface 21, and sliding surface 24 of the slide 20 are all provided with a first sliding material shallow groove 28. When in use, the side and bottom of the slide 20 need to be lubricated to reduce friction between the slide 20 and other components. The provision of the first sliding material shallow groove 28 can store the lubricating grease and prevent the lubricating grease from being consumed too quickly.

[0050] An ejection assembly is provided in the mounting groove 19, and the ejection assembly includes a fixed plate 29 and a top plate 30 corresponding to the 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 ejector pins 31 arranged in parallel and passing through the main insert 18. The needle heads of the ejector pins 31 are fixed on the fixed plate 29. The fixing method of the ejector pins 31 and the fixed plate 29 can be achieved by any existing technology. The upper surface of the ejector pins 31 and the surface at the corresponding position of the main insert 18 are in 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 fixed plate 29 is provided with at least two springs 32 connected to the bottom of the main insert 18. In the first stage of mold separation, the main insert 18 begins to be demolded, while the fixed plate 29 maintains a constant height. The distance between the main insert 18 and the fixed plate 29 is continuously shortened. The function of the spring 32 is to act as a buffer when the two move relative to each other. In the second stage of mold separation, the spring 32 begins to reset, relying on its elastic potential energy to further press the slide 20 to fit the guide block 8, thereby reducing the jitter of the slide 20. The spring 32 is arranged in a rectangular array or annular array to ensure the uniformity of the force applied to it and the fixed plate 29. The bottom of the slider 10 is provided with a sealing block 33 that seals the notch of the mounting groove 19. The sealing block 33 is fixed to the slider 10 by screws. The sealing block 33 is provided with two guide posts 34 arranged symmetrically and parallel to the ejector pins 31. The lower ends of the guide posts 34 are fixed to the sealing block 33 by screws. The fixed 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 fixed 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 force applied to the fixed plate 29 is uniform, so that the fixed plate 29 and the top plate 30 can move smoothly without deviation. In the second stage of mold separation, the top plate 30 gradually moves closer to the sealing block 33 until it contacts it. The bottom of the top plate 30 is provided with multiple elastic pads 35 to provide a buffer when the top plate 30 reaches the sealing block 33, preventing the top plate 30 from directly hitting the sealing block 33.

[0051] The packaging block 33 is provided with at least two positioning posts 36, which are fixed to the packaging block 33 via screws. The other ends of the positioning posts 36 extend to the bottom of the mounting slot 19. The positioning posts 36 are used to limit the depth of the packaging block 33 into the mounting slot 19, ensuring the accurate installation position of the packaging block 33. The packaging 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 coplanar, ensuring that the slider 10 can slide normally.

[0052] The guide sliding surface 15 of the upper mold 1 is provided with a guide sliding convex strip 38 of the same slope along its length direction, and the demoulding guide inclined surface 14 of the slider 10 is provided with a guide sliding groove 39 matching the guide sliding convex strip 38, so as to prevent the slider 10 from deflecting when sliding, and a limiting column 40 is provided on the demoulding guide inclined surface 14, one end of the limiting column 40 is embedded in the slider 10 and fixedly connected to the slider 10, and the limiting column 40 is perpendicular to the demoulding guide inclined surface 14, and the guide sliding surface 15 is provided with a limiting groove 41 that matches the limiting post 40 and is parallel to the guide slide convex strip 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 a screw. After installation, the guide slide surface 15 does not produce a convex 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 parted, the slider 10 stops sliding when the limiting post 40 falls into the tiger buckle 42 and is engaged. In this way, the slider 10 stroke is controlled to prevent the slider 10 from completely separating from the upper mold 1. The tiger buckle 42 can be implemented by any technology. It is necessary to meet the requirements that the limiting post 40 can be engaged when entering the tiger buckle 42, and the limiting post 40 can be normally separated when it is reversely separated from the tiger buckle 42.

[0053] The lower mold 2 is provided with a fourth inclined surface 43 corresponding to the sliding inclined surface 11, which 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 base 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 lower mold 2. The wear-resistant plates 44 are used for friction to protect the bodies of the upper mold 1 and lower mold 2. The wear-resistant plates 44 are provided with a second sliding shallow groove 45 on the outward side. When in use, lubricating grease is applied to the wear-resistant plates 44. The second sliding shallow groove 45 is used to store lubricating grease to 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 a combination of strips, arcs, circles, rectangles, and other shapes.

[0054] The upper mold 1 is provided with multiple upper positioning blocks 46, and the lower mold 2 is provided with multiple lower positioning blocks 47 corresponding to the upper positioning blocks 46 respectively. The upper positioning blocks 46 are provided with positioning protrusions extending toward 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 closing state, and the mold separation begins after the injection is completed. In the first stage of mold separation, the upper mold core 3 and the lower mold core 4 begin to separate and demould; the slider 10 and the lower mold 2 are gradually separated downward by the fit of the sliding inclined surface 11 and the fourth inclined surface 43, and the guidance of the guide rod 9, and the slider 10 drives the main insert 18 to slide downward and demould; at the same time, the slider 10 and the upper mold 1 are fit by the fit of the demoulding guide inclined surface 14 and the guide sliding surface 15, and the cooperation of the sliding ridge 13 and the slide groove 12, With the cooperation of the guide slide ridge 38 and the guide slide groove 39, the slider 10 will slide at a predetermined slope when sliding downward. At this stage, the sliding surface 24 at the lower end of the slider 20 is in contact with the transition surface 22 of the guide block 8 to slide horizontally. 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. Driven by the slider 10, the main insert 18 gradually moves downward toward the fixed plate 29, shortening the distance between the two. The first stage of mold parting is completed, and only the ejector pin 31 and the inclined ejector 25 remain to support the product. During the second stage of mold separation, as the mold separation continues, the first inclined surface 21 of the slide 20 begins to mate with the second inclined surface 23 of the guide block 8. The slide 20 gradually slides downward, driving the fixed plate 29 and the ejector pin 31 downward to release the mold. The distance between the fixed plate 29 and the main insert 18 gradually returns to its original spacing. At the same time, as the slide 20 slides downward, it drives the inclined ejector 25 to slide rightward along the inclined ejector groove 27, and the upper end of the inclined ejector 25 gradually separates from the product. The slider 10 continues to slide along the track of the first stage between the upper mold 1 and the lower mold 2, maintaining the sliding mode and track of the first stage. At the end of the sliding stroke, the limit post 40 engages the tiger buckle 42, and the slider 10 stops sliding, completing the mold separation. During the mold closing, the slider 10 is guided by the guide rod 9 between the slider 10 and the lower mold 2, driving the slider 10 to slide upward and reset. At the same time, the limit post 40 between the slider 10 and the upper mold 1 disengages the tiger buckle 42, and the slider 10 slides upward and resets.
