Description

Technical Field

[0001] This invention relates to the field of rubber parts manufacturing technology, and in particular to a rubber mold that facilitates demolding. Background Technology

[0002] Rubber products, as an important byproduct of plastic waste recycling, play an increasingly important role in resource recycling and environmental protection. Reclaimed rubber materials, made by recycling waste plastics and adding appropriate additives, can be widely used in various industrial and consumer products such as gaskets, seals, and shock-absorbing components. However, in the production process of rubber products, the demolding efficiency and ease of operation of the molds directly affect production efficiency and cost control.

[0003] In existing technologies, the production process of rubber stamped parts typically employs a split-type mold structure. This structure mainly consists of two parts: a separate mold base slide and a stamping table. The mold base slide carries the lower mold and moves on a horizontal track, while the stamping table has the upper mold (stamping head) and drive device fixedly mounted on it. In a typical production cycle, the slide is first controlled to move horizontally to a position directly below the stamping head. Then, the stamping device is activated to make the stamping head perform a long-stroke vertical descent motion to complete the stamping of the rubber material placed in the lower mold cavity.

[0004] This traditional structure has obvious shortcomings in actual production: First, the excessively long stamping stroke leads to low efficiency. Because the slide and stamping table are independently set, the slide must be allowed to move into position and lock before each stamping operation. Afterward, the stamping head needs to perform a long vertical movement from a high standby position. This prolongs the cycle time of a single stamping operation and increases equipment wear and energy consumption. Especially for thin rubber products, the actual effective working stroke of the stamping head is very short, but a long idle stroke must be reserved to avoid the sliding table's movement space, resulting in a double waste of time and energy.

[0005] Secondly, the demolding process relies on manual operation, which poses safety risks and is inefficient. After stamping, the slide needs to carry the formed part (along with the lower die) from the stamping area to the part removal station. At this time, the stamped part is often stuck in the lower die cavity, requiring operators to remove it using tools or by hand. This not only increases the labor intensity of workers, but also poses a risk of burns due to the high temperature of the newly formed rubber parts. Furthermore, manual part removal is slow, becoming a bottleneck in production cycle time and severely restricting the realization of automated continuous production.

[0006] Furthermore, the equipment layout occupies a large space. The independent slide rails and the vertical working space of the stamping table need to be reserved separately, resulting in a large footprint for the entire mold equipment, which is not conducive to the space utilization of the production workshop. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides a rubber mold that is easy to demold. This design effectively solves the problems in the production of existing rubber products, such as the long stamping stroke of the split mold structure during stamping and the reliance on manual operation for demolding, which leads to low production efficiency, large equipment wear and high labor intensity for workers.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a frame, a support platform fixedly connected to the frame, a slide table slidably connected to the support platform, a guide assembly installed between the slide table and the support platform, a storage groove provided on the slide table, a mold sleeve provided in the storage groove, a flipping frame fixedly connected to the side of the mold sleeve, the flipping frame hinged to the slide table, a pressing assembly fitted above the mold sleeve, a lifting frame slidably connected to the pressing assembly, the lifting frame slidably connected to the support platform, connecting plates fixedly connected to both sides of the lifting frame, the two connecting plates respectively located on both sides of the slide table, a synchronization assembly fitted between the connecting plates and the slide table, the slide table driving the connecting plates to move vertically through the synchronization assembly.

[0009] Preferably, the synchronization component includes a connecting pin, which is fixedly connected to the connecting plate, and the slide table has a first slide groove on both sides for the connecting pin to slide, the first slide groove having a Z-shaped structure.

[0011] Preferably, the guide assembly includes an electromagnetic slide rail, which is fixedly connected to the support platform. The slide table is slidably connected to the electromagnetic slide rail. The slide table is provided with a guide hole, and a second guide rod is slidably connected in the guide hole. The length of the second guide rod is the same as the lateral length of the first slide groove.

[0012] Preferably, the mold sleeve includes, from bottom to top, a cavity plate, an upper template and a boss plate. The cavity plate is provided with a mold cavity, and a positioning pin is fixedly connected to the cavity plate. The upper template is provided with a positioning hole for the positioning pin to pass through.

[0013] Preferably, the upper template is fixedly connected to both sides of an extension platform, and the storage slot is provided with slots on both sides that cooperate with the extension platforms.

[0014] Preferably, the flipping frame is fixedly connected to the cavity plate, the flipping frame has an L-shaped structure, the middle part of the flipping frame is hinged to the slide table, the lower end of the flipping frame is hinged to a first telescopic rod, and the other end of the first telescopic rod is hinged to the slide table.

[0015] Preferably, a locking pin is fixedly connected to the flipping frame, a locking block is fitted on the locking pin, the locking block is fixedly connected to the boss plate, and a gap is left between the bottom of the locking pin and the locking block.

[0016] Preferably, a storage basket is fixedly connected to the front side of the frame, and the storage basket is located below the slide table.

[0017] Preferably, the die assembly includes a stamping plate, the cross-sectional dimensions of which are the same as those of the die sleeve, and a second telescopic rod is installed between the stamping plate and the lifting frame.

[0018] Compared with the prior art, the outstanding advantages of the present invention are: This application provides a connecting plate and a synchronization component between the lifting frame and the slide. The slide can drive the connecting plate to move vertically through the linkage of the synchronization component, thereby realizing the automatic lifting and lowering of the die assembly, effectively shortening the stamping stroke of the die assembly, improving production efficiency and reducing energy consumption.

[0019] This application installs a tilting frame between the mold sleeve and the slide table. By changing the placement angle of the mold sleeve through the tilting frame, the molded rubber products can be automatically or semi-automatically removed from the mold during demolding and part removal. This significantly reduces the labor intensity and risk of burns from manual operation, and improves demolding efficiency and automation level. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1-9 This embodiment provides a rubber mold for easy demolding: it includes a frame 1, a support platform 2 fixedly connected to the frame 1, a slide 3 slidably connected to the support platform 2, a guide assembly 4 installed between the slide 3 and the support platform 2, a storage groove 5 on the slide 3, a mold sleeve 6 inside the storage groove 5, a flipping frame 7 fixedly connected to the side of the mold sleeve 6, the flipping frame 7 being hinged to the slide 3, a pressing assembly fitted above the mold sleeve 6, a lifting frame 9 slidably connected to the pressing assembly, the lifting frame 9 being slidably connected to the support platform 2, connecting plates 10 fixedly connected to both sides of the lifting frame 9, the two connecting plates 10 being located on both sides of the slide 3, a synchronization assembly 11 fitting between the connecting plates 10 and the slide 3, the slide 3 driving the connecting plates 10 to move vertically through the synchronization assembly 11.

[0032] The frame 1 is the basic structure of the entire mold device, used to support and fix other components to ensure the stable operation of the equipment. The support platform 2 is fixedly connected to the frame 1, providing horizontal support and guidance for the slide table 3. It is the bearing platform of the mold working area. The slide table 3 is set on the support platform 2 and can slide along the support platform 2. It is used to support the mold sleeve 6 and the flipping frame 7 and move between the stamping and demolding stations. The guide assembly 4 is installed between the slide table 3 and the support table 2 to guide the slide table 3 to slide precisely horizontally on the support table 2, ensuring the accuracy of its movement trajectory. The storage slot 5 is set on the slide table 3 to accommodate the mold sleeve 6, ensuring the positioning and stability of the mold sleeve 6 on the slide table 3. The mold sleeve 6 is the part that directly contacts the rubber raw material and is formed. It has a mold cavity 604 inside to form the shape of the rubber product. The flipping frame 7 is fixedly connected to the front side of the mold sleeve 6 and hinged to the slide table 3. It is used to drive the mold sleeve 6 to flip during the demolding process, so that the mold sleeve 6 is in an inclined state to facilitate the removal of the product. The pressing assembly is located above the mold sleeve 6 and is used to apply pressure to the rubber raw material inside the mold sleeve 6 to complete the stamping process. The lifting frame 9 is slidably connected to the support table 2 and carries the pressing assembly. It can move vertically to realize the lifting action of the pressing assembly. The connecting plate 10 is fixedly connected to both sides of the lifting frame 9 and located on both sides of the slide table 3. It serves as a connecting component between the lifting frame 9 and the synchronization component 11. The synchronization component 11 is fitted between the connecting plate 10 and the slide table 3. Its function is to drive the connecting plate 10 to move vertically when the slide table 3 moves horizontally, thereby realizing the synchronization of the automatic lifting and demolding action of the molding assembly.

[0033] The frame 1 serves as the basic support structure for the entire equipment and can be fixed to the ground or workbench by welding or bolting. A support platform 2 is fixedly connected to the frame 1. The support platform 2 is a flat plate structure used to support the subsequent moving component slide table 3. The slide table 3 is a rectangular platform, and its bottom cooperates with the electromagnetic slide rail 401 on the support platform 2 to achieve horizontal movement, thereby ensuring the stability and positioning accuracy of the slide table 3 during horizontal movement.

[0034] Connecting plates 10 are fixedly connected to both sides of the lifting frame 9. These connecting plates 10 can be made of steel plates and are connected to the lifting frame 9 by bolts or welding. The two connecting plates 10 are located on the left and right sides of the slide table 3, respectively, maintaining a certain gap with the slide table 3. A synchronization component 11 is fitted between the connecting plates 10 and the slide table 3. The synchronization component 11 can be composed of a simple connecting pin 1101 and a roller 1103. When the slide table 3 moves horizontally, the connecting pin 1101 moves along the first slide groove 1102. The first slide groove 1102 has a Z-shaped structure. Under the interaction of the first slide groove 1102 and the first guide rod 1105, the connecting plates 10 are driven to move vertically. Thus, the slide table 3 can drive the connecting plates 10 to move vertically through the linkage of the synchronization component 11, thereby realizing the automatic lifting of the lifting frame 9. For example, when the slide table 3 moves from the stamping station to the demolding station, the synchronization component 11 can drive the connecting plate 10 and the lifting frame 9 to move upward, so that the mold assembly disengages from the mold sleeve 6; when the slide table 3 moves from the demolding station to the stamping station, the synchronization component 11 can drive the connecting plate 10 and the lifting frame 9 to move downward, so that the mold assembly engages with the mold sleeve 6. When the lifting frame 9 moves the mold assembly to the lowest position, there will be a short gap between the mold assembly and the mold sleeve 6, thus ensuring that the slide table 3 does not interfere with the mold assembly when it moves.

[0035] Meanwhile, through the linkage design of the slide table 3 and the synchronization component 11, the automatic lifting and lowering of the die assembly and the horizontal movement of the die sleeve 6 are synchronized, which effectively shortens the stamping stroke, improves production efficiency and reduces energy consumption.

[0036] To reduce the friction between the connecting pin 1101 and the first slide groove 1102, a roller 1103 is installed on the inner side of the connecting pin 1101. The roller 1103 rotates with the second slide groove 1104. The rolling friction between the roller 1103 and the second slide groove 1104 makes the movement of the connecting pin 1101 smoother and reduces energy loss. At the same time, each connecting rod has two first guide rods 1105 on its support rod. The first guide rods 1105 are located inside the guide sleeve 1106, which contains a linear bearing to ensure the smooth longitudinal movement of the first guide rods 1105. The first guide rods 1105 are rod-shaped structures fixed to the bottom of the connecting plate 10. Their main function is to provide additional vertical guidance and support for the connecting plate 10, ensuring that the connecting plate 10 remains stable during lifting and lowering and reducing swaying. The first guide rod 1105 can be a solid or hollow rod in cylindrical, square, or other cross-sectional shapes, and is securely fixed to the bottom of the connecting plate 10 by bolts, welding, or riveting. The guide sleeve 1106 is a sleeve-shaped structure fixed to the support platform 2. It cooperates with the first guide rod 1105 to form a sliding pair, providing a precise guiding path for the first guide rod 1105 and further restricting the lateral displacement of the connecting plate 10, ensuring that it moves only in the vertical direction. The guide sleeve 1106 can be made of wear-resistant materials such as bronze, engineering plastics, or hard alloys to reduce friction and wear, and is fixed to the support platform 2 by bolts, press-fitting, or welding. The inner diameter of the guide sleeve 1106 is tightly fitted with the outer diameter of the first guide rod 1105, with an appropriate clearance to allow smooth sliding. The sliding connection between the first guide rod 1105 and the guide sleeve 1106 ensures smooth and precise movement of the connecting plate 10 in the vertical direction, while bearing part of the vertical load, reducing the lateral force on the connecting pin 1101 in the synchronization assembly 11, and improving the stability of the entire lifting system. To further reduce friction, a lubricant can be applied to the sliding surface, or a self-lubricating bushing can be installed inside the guide sleeve 1106.

[0037] The electromagnetic slide rail 401 is a guiding device that uses electromagnetic force to achieve contactless or low-friction sliding. It typically consists of an electromagnetic coil and a magnetic conductor. By precisely controlling the magnetic field generated by the current, the slide table 3 moves on the track with extremely low friction. The electromagnetic slide rail 401 is fixedly connected to the support platform 2, ensuring it serves as a stable guiding reference and providing a precise movement path for the slide table 3. The sliding connection between the slide table 3 and the electromagnetic slide rail 401 is achieved through electromagnetic force or a slider with magnetic material, ensuring the smooth movement of the slide table 3. Furthermore, the slide table 3 is provided with a guide hole 402, which provides installation and sliding space for the second guide rod 403. Its inner wall can be finely machined to reduce friction. The second guide rod 403 is slidably connected within the guide hole 402, serving as an auxiliary guiding or limiting structure, further enhancing the stability of the slide table 3. Specifically, the length of the second guide rod 403 is designed to be the same as the lateral length of the first slide groove 1102. The two extreme positions of the slide table 3 correspond to the two extreme positions of the lifting frame 9. That is, when the slide table 3 moves backward to the rear extreme position of the second guide rod 403, the lifting frame 9 drives the die assembly to move downward to the position directly above the die sleeve 6. At this time, there is a minimum gap between the die assembly and the die sleeve 6, and the die assembly can perform rapid die pressing. Conversely, when the slide table 3 moves to the front extreme position of the second guide rod 403, the lifting frame 9 rises to the highest position. At this time, the front side of the support platform 2 of the slide table 3 is supported, making it easy to remove the internal stamped parts. The second guide rod 403 can work in conjunction with the lateral part of the first slide groove 1102 to provide additional lateral support or limit, thereby ensuring the accuracy of the movement trajectory when the slide table 3 moves laterally. The introduction of the electromagnetic guide rail 401 significantly improves the smoothness and precision of the slide table 3's movement, effectively avoiding the jamming and shaking problems that may occur with traditional mechanical guides. At the same time, the cooperation between the second guide rod 403 and the guide hole 402, as well as the precise matching of its length with the lateral length of the first slide groove 1102, provides more precise lateral support and limiting when the slide table 3 performs Z-shaped movements. This effectively suppresses lateral offset or shaking that may be caused by the oblique force of the Z-shaped groove. This not only ensures the precise path control and positioning of the slide table 3 throughout the demolding process, thereby improving the efficiency of mold demolding and product quality, but also extends the service life of the equipment by reducing mechanical friction.

[0038] The mold sleeve 6 is divided into a cavity plate 601, an upper template 602, and a boss plate 603 from bottom to top. It incorporates a mating structure of locating pins 605 and locating holes 606, effectively solving the problem of misalignment during the assembly of internal mold components. The precise fit between the locating pins 605 and locating holes 606 ensures accurate alignment of the cavity plate 601 and the upper template 602 during assembly, thereby guaranteeing the integrity and molding accuracy of the mold cavity 604 and preventing defects in rubber products caused by mold misalignment. Furthermore, this layered structure makes mold maintenance and replacement more convenient. For example, when it is necessary to replace the mold cavity 604 with a different shape, only the cavity plate 601 needs to be replaced, without replacing the entire mold sleeve 6, significantly improving mold flexibility and production efficiency. Overall, through the refined internal structure design of the mold, this application can guarantee the molding quality and consistency of rubber products and improve the efficiency of mold use.

[0039] The extension platform 607 is a structure fixedly connected to both sides of the upper template 602. Its function is to provide an outwardly extending support or connection part. Specifically, the extension platform 607 is a protruding structure integrally formed on both sides of the upper template 602. Its material is usually the same as or has similar strength and wear resistance as the upper template 602 to ensure structural stability. The size and shape of the extension platform 607 should match the slot 12 to achieve a stable fit.

[0040] The slot 12 is a groove structure set on both sides of the storage slot 5, used to cooperate with the extension platform 607 of the upper template 602, thereby limiting and fixing the upper template 602. Specifically, the slot 12 is a groove directly machined into the wall of the storage slot 5. The shape and depth of the slot 12 should be precisely designed to ensure that the extension platform 607 can slide in smoothly and be firmly locked, preventing the upper template 602 from shifting in the horizontal direction. The length of the slot 12 is greater than the length of the extension platform 607. The two extension platforms 607 on both sides can be gripped from the sides of the slot 12, which facilitates the subsequent demolding work.

[0041] The flipping frame 7 is fixedly connected to the cavity plate 601. The flipping frame 7 has an L-shaped structure, with its middle section hinged to the slide table 3. A first telescopic rod 13 is hinged to the lower end of the flipping frame 7, and the other end of the first telescopic rod 13 is hinged to the slide table 3. As a key component for flipping the mold sleeve 6, the connection method between the flipping frame 7 and the mold sleeve 6 directly affects the stability of the flipping and the demolding effect. Fixing it to the cavity plate 601 ensures that the flipping force acts directly on the core part of the mold sleeve 6—the cavity plate 601—thereby driving the entire mold sleeve 6 to move synchronously during flipping, providing a stable foundation for subsequent mold separation operations. Figure 4 and Figure 6As shown, the flipping frame 7 adopts an L-shaped structure, characterized by having two mutually perpendicular arms. In this application, the L-shaped structure can provide a lever arm, enabling the flipping frame 7 to generate greater torque during the flipping process. At the same time, the L-shaped structure design also facilitates subsequent hinge and connection with other components. For example, one arm can be used to fix it to the cavity plate 601, while the other arm can be used to hinge it to the slide table 3 or connect it to the telescopic rod. This structure helps to optimize the flipping trajectory and stability.

[0042] Based on this, the middle part of the flipping frame 7 is hinged to the slide table 3. Choosing the middle part as the hinge point allows the two ends of the flipping frame 7 (one end connecting the cavity plate 601 and the other end connecting the telescopic rod) to move in a relatively balanced manner during flipping, reducing swaying and instability during the flipping process. At the same time, the lower end of the flipping frame 7 is hinged to the first telescopic rod 13. The first telescopic rod 13 is a mechanical component that can change its own length. Driven by hydraulic, pneumatic or mechanical means, it is hinged to the lower end of the flipping frame 7, which can assist in controlling the movement of the flipping frame 7. During the flipping process, the extension and retraction of the first telescopic rod 13 can provide thrust or pull force to precisely control the flipping angle and speed. This hinge method allows the telescopic rod to work effectively at different angles. The other end of the first telescopic rod 13 is hinged to the slide table 3, forming a linkage mechanism. When the slide table 3 moves, the extension and retraction of the first telescopic rod 13 drives the flipping frame 7 to flip, realizing the tilting of the mold sleeve 6, which facilitates the removal of the rubber product.

[0043] A locking pin 14 is fixedly connected to the flipping frame 7, and a locking block 15 is fitted on the locking pin 14. The locking block 15 is fixedly connected to the boss plate 603. A gap is left between the connecting pin 1101 and the bottom of the locking block 15. Specifically, the locking pin 14 is a protruding structure set on the flipping frame 7. Its function is to provide a mechanical connection point so as to establish a connection with the boss plate 603 in the mold sleeve 6. The locking pin 14 is securely installed on the tilting frame 7, ensuring it will not loosen or fall off under stress. The locking block 15 is a structure that matches the locking pin 14, used to clamp the locking pin 14, thereby achieving the connection between the tilting frame 7 and the boss plate 603. The locking block 15 has an L-shaped structure. When the locking pin 14 and the locking block 15 are engaged, they form a relatively stable connection. The boss plate 603 can be tightly attached to the upper template 602, ensuring the stability between the boss plate 603 and the upper template 602. When the slide table 3 moves, it ensures that the boss plate 603 is always located above the upper template 602. During stamping, the boss plate 603 is in direct contact with the die assembly. Figure 2As shown, during the demolding of mold sleeve 6, the flipping operation is first performed by the flipping frame 7. The locking block 15 then drives the boss plate 603 to move synchronously. After the boss plate 603 rotates to an inclined state, it is pushed downwards. Under the combined action of gravity and external force, the boss plate 603 can slide downwards relative to the upper mold plate 602, thus completing the demolding action of the boss plate 603. After the locking block 15 is fixedly connected to the boss plate 603, a specific gap is reserved between its bottom and the connecting pin 1101. This gap is designed to ensure that when the boss plate 603 is pressed downwards, it has room to move downwards, allowing the boss plate 603 to directly transmit the downward force to the upper mold plate 602.

[0044] A locking pin 14 is provided on the flipping frame 7, and the locking pin 14 cooperates with the locking block 15 fixedly connected to the boss plate 603, so as to realize a reliable connection between the flipping frame 7 and the boss plate 603. When the flipping frame 7 performs a flipping operation, the boss plate 603 can be firmly driven by the locking block 15, which facilitates the subsequent demolding work of the boss plate 603.

[0045] A storage basket 16 is fixedly connected to the front of the frame 1, located below the front of the slide table 3. The storage basket 16 is a container for collecting demolded rubber products. The top of the storage basket 16 is open to allow for centralized storage of the products. The storage basket 16 is fixedly connected to the frame 1, for example, through welding or bolting, to ensure its stability and reliability during equipment operation and prevent displacement or detachment due to vibration or impact. The front of the frame 1 is the preferred installation position for the storage basket 16, typically a location easily accessible and convenient for observation and retrieval by operators. Located below the slide table 3, the storage basket 16 allows the rubber products to fall directly and automatically into the storage basket 16 under the weight of the mold sleeve 6 on the slide table 3 after demolding in an inclined state. This positional relationship is crucial for achieving automatic collection.

[0046] Through the above technical solution, a collection basket 16 is fixedly connected to the front side of the frame 1 and placed below the slide table 3, so that the demolded rubber products can fall directly and automatically into the collection basket 16. This effectively solves the problem of products falling randomly and piling up haphazardly, avoids the tediousness and inefficiency of manual collection, significantly improves the automation level and operating efficiency of the production line, and maintains a clean working environment.

[0047] The cross-sectional dimensions of the stamping plate 801 are the same as those of the mold sleeve 6, ensuring that the stamping plate 801 can completely cover or precisely enter the forming area of ​​the mold sleeve 6 during the molding process. This dimensional matching ensures that the molding force is evenly distributed across the entire rubber material, avoiding defects caused by uneven local force, such as incomplete forming of the product edges or insufficient pressure in the central area. For example, if the mold sleeve 6 is rectangular, the stamping plate 801 is also rectangular of the same size; if the mold sleeve 6 is circular, the stamping plate 801 is also circular of the same diameter. This precise dimensional fit is key to achieving high-quality rubber product molding. The second telescopic rod 802 is installed between the stamping plate 801 and the lifting frame 9. This telescopic rod is a hydraulic telescopic rod. When the lifting frame 9 descends to the lowest position for molding, the second telescopic rod 802 drives the stamping plate 801 to move downwards, thereby enabling the stamping plate 801 to complete the rubber mold stamping work within a short stroke distance.

[0048] A stamping plate 801 is incorporated into the molding assembly. Its cross-sectional dimensions are identical to those of the mold sleeve 6, ensuring comprehensive and uniform pressure on the rubber material during molding and effectively preventing uneven molding or molding defects. Simultaneously, a second telescopic rod 802 installed between the stamping plate 801 and the lifting frame 9 reduces the distance the stamping plate 801 needs to move. This design not only improves the molding quality and consistency of rubber products but also effectively reduces the impact on the mold and equipment during molding, extending their service life.

[0049] The overall workflow of this invention is as follows: When the operator starts the equipment, a piece of unformed rubber material is first placed in the mold cavity 604 of the mold sleeve 6 cavity plate 601. At this time, the slide table 3 is located in the loading / unloading position of the equipment (the foremost side of the support table 2), and the molding assembly is in a higher standby position.

[0050] To perform the stamping process, the slide table 3 begins to move horizontally along the electromagnetic slide rail 401 on the support platform 2 towards the stamping station. During the horizontal movement of the slide table 3, the first slide grooves 1102 (Z-shaped structure) on both sides drive the connecting pin 1101 to move. Since the connecting pin 1101 is fixedly connected to the connecting plate 10, and the connecting plate 10 is fixedly connected to the lifting frame 9, the horizontal movement of the slide table 3 is converted into the vertical movement of the connecting plate 10 and the lifting frame 9 through the Z-shaped slide groove structure of the synchronization component 11. Specifically, when the slide table 3 moves to the stamping station, a specific section of the Z-shaped slide groove guides the connecting pin 1101 to move downward, thereby causing the connecting plate 10 and the lifting frame 9 to descend synchronously. When the lifting frame 9 descends, the die assembly below it also descends accordingly.

[0051] The downward stroke of the die assembly is synchronized with the horizontal movement of the slide table 3, which significantly shortens the stamping cycle time and improves production efficiency. After the slide table 3 moves to the stamping station, the die assembly hovers above the die sleeve 6. After the slide table 3 stops, the die assembly performs downward stamping. When the stamping is completed, the die assembly returns upward, and the slide table 3 moves horizontally in the opposite direction, leaving the stamping station. At this time, the other section of the Z-shaped slide guides the connecting pin 1101 to move upward, causing the connecting plate 10 and the lifting frame 9 to rise synchronously, completing the reset.

[0052] Once the slide 3 returns to the loading / unloading position and the molding assembly is fully raised, the rubber product inside the mold sleeve 6 has been formed. At this point, the tilting frame 7 comes into play, which can drive the mold sleeve 6 to tilt. The tilting frame 7 can be driven to tilt at a certain angle, causing the mold sleeve 6 to tilt downwards. Under the action of gravity, the formed rubber product automatically falls out of the mold cavity 604. A collection basket 16 is fixedly connected to the front side of the equipment frame 1, located below the slide 3, for collecting the fallen rubber product.

[0053] This automatic flipping and demolding method avoids the risk of burns and inefficiency associated with manual part handling, improves operational safety, and makes the production process more automated. The entire stamping and demolding process is tightly integrated. The horizontal movement of the slide table 3 not only completes the station switching but also simultaneously drives the vertical movement of the die assembly and the flipping and demolding of the mold sleeve 6, making the equipment structure more compact and effectively reducing the floor space required.

[0054] Through the aforementioned collaborative work, the easily demolded rubber mold achieves optimized stamping stroke, automated demolding process, and compact equipment footprint, solving the problems of low efficiency, high safety risks, and large space occupation in traditional rubber product manufacturing.
