Description

Technical Field

[0001] This invention relates to the field of mold parting machine technology, specifically to a high-precision vertical mold parting machine with multi-axis collaborative control. Background Technology

[0002] In injection molding, die casting, and other manufacturing processes, vertical mold parting machines are key auxiliary equipment for mold separation and waste plastic recycling. Widely used in plastic product processing and mold repair, their performance directly affects parting accuracy, operational efficiency, and resource recycling rate, playing a crucial role in ensuring product quality and reducing production costs. Waste plastic recycling, as a vital supporting step in mold parting, not only reduces resource waste and production costs but also aligns with the energy-saving and environmentally friendly industrial development needs, making it an important component of green production in modern manufacturing. Currently, vertical mold parting machines on the market still face several technical challenges in practical applications, particularly in the waste plastic recycling stage, where design deficiencies make it difficult to meet the demands of modern intelligent production lines for high precision, high efficiency, integrated operation, and green recycling. Specifically:

[0003] First, the existing vertical mold parting machines have unreasonable drive and guide structure designs, making it difficult to guarantee mold parting accuracy. Most traditional mold parting machines use a single drive cylinder to drive the lifting frame, resulting in uneven driving force. This can easily lead to tilting and jamming during the lifting process, affecting the accuracy of mold positioning. At the same time, the guide structure of the lifting frame is simple, relying only on a single guide rail or guide rod for limiting, lacking multiple limiting and guiding guarantees. This can easily cause deviation during the lifting process, leading to misalignment of the upper and lower molds. This not only affects the quality of mold parting but may also cause mold wear and reduce the mold's service life.

[0004] Secondly, existing mold-separating machines suffer from poor coordination among their components, resulting in low operational efficiency. Furthermore, the waste plastic recycling process is disconnected from the mold-separating operation, leading to unsatisfactory recycling results. Traditional mold-separating machines often have independently controlled lifting, mold clamping, and waste plastic crushing actions, requiring multiple independent drive mechanisms. This not only increases equipment complexity and manufacturing costs but also creates time differences between actions, preventing synchronized operation. For example, mold clamping cannot be completed simultaneously during the lifting frame's descent; the clamping mechanism must be activated separately after the lifting frame reaches its position, extending the cycle time. Simultaneously, waste plastic crushing often requires separate drive components, disconnected from the mold-separating operation. The timing of crushing does not match the mold-separating rhythm, occupying equipment space, increasing energy consumption, and easily leading to waste plastic accumulation, affecting the normal operation of the mold-separating process. In addition, the crushed plastic particles lack a standardized collection and guidance structure, making centralized collection difficult. Some particles scatter inside the equipment or in the working environment, affecting resource recycling rates, increasing material waste, polluting the working environment (contrary to green production principles), and increasing subsequent cleanup workload. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-precision vertical mold parting machine with multi-axis collaborative control, which solves the problems mentioned in the background technology.

[0006] The solution of the present invention to the above-mentioned technical problems is as follows:

[0007] This invention provides a multi-axis collaborative control high-precision vertical mold parting machine, comprising:

[0008] A frame, on which a lifting frame is slidably mounted, and a base and a crushing mechanism are mounted on the frame below the lifting frame;

[0009] The lifting frame is used to install the upper mold;

[0010] The base includes a base and a clamping block and a second push plate disposed thereon;

[0011] The lifting frame is connected to a drive device that drives its lifting and lowering.

[0012] The lifting frame is equipped with a guide rod, which is connected to the rotating cutter head of the crushing mechanism. When the lifting frame descends, the guide rod is driven to rotate, which in turn drives the rotating cutter head to rotate to crush the waste plastic.

[0013] The lifting frame is equipped with a guide push rod, and the frame is equipped with an air cylinder. The end of the guide push rod extends into the air cylinder and is fitted with a piston plate. The air cylinder is connected to the fifth drive cylinder on the base through a pipeline. The fifth drive cylinder is used to drive the second push plate to move. When the lifting frame descends, the guide push rod drives the medium in the air cylinder to enter the fifth drive cylinder, causing the second push plate to move to cooperate with the clamping block to clamp the lower mold.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the driving device includes a first driving cylinder and a second driving cylinder mounted on the frame, and a driving pump for driving the first driving cylinder and the second driving cylinder. The output ends of the first driving cylinder and the second driving cylinder are connected and fixed to the lifting frame. Guide rails are provided on both sides of the frame, and pulleys are provided on both sides of the lifting frame. The lifting frame descends smoothly through the cooperation of the pulleys and the guide rails.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] By cooperating with the first and second drive cylinders and the drive pump, the multi-axis coordinated drive of the lifting frame is realized. Compared with the single drive cylinder structure, it can provide a more balanced and stable driving force, avoid tilting or jamming during the lifting process, and ensure the smoothness and synchronization of the lifting action. The guide rails on both sides of the frame and the pulleys on both sides of the lifting frame cooperate with each other to form a precise guiding structure, further reducing the frictional resistance during the movement of the lifting frame, ensuring that the lifting frame rises and falls smoothly along the preset trajectory, laying the foundation for subsequent precise positioning, clamping and mold separation operations of the mold, while reducing component wear, extending the service life of the drive device and the lifting frame, and improving the stability and reliability of the equipment operation.

[0018] Furthermore, the lifting frame includes a fixed frame, and a connector is installed on the lower surface of the fixed frame. The guide push rod is installed on the connector. The output ends of the first drive cylinder and the second drive cylinder are connected and fixed to the fixed frame. A third drive cylinder and a fourth drive cylinder are installed on the fixed frame. The output end of the third drive cylinder passes through the fixed frame and is equipped with a claw hook. The output end of the fourth drive cylinder passes through the fixed frame and is equipped with a first push plate. The top of the upper mold is provided with a first fixed seat. The upper mold is installed below the fixed frame by cooperating with the first fixed seat through the claw hook. At the same time, the fourth drive cylinder drives the first push plate to press the first fixed seat. The first fixed seat is clamped and fixed by the interaction of the first push plate and the claw hook, thereby installing the upper mold on the fixed frame.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] As the core load-bearing component of the lifting frame, the fixed frame provides a stable mounting base for each drive cylinder, guide push rod, and upper mold. The connector makes the guide push rod more securely installed, preventing it from loosening or shifting during lifting and ensuring the coordinated linkage effect between the guide push rod and the air cylinder. The third and fourth drive cylinders drive the claw hook and the first push plate respectively. Through the snap-fit ​​between the claw hook and the first fixed seat, and the pressing action of the first push plate on the first fixed seat, a double clamping and fixing structure is formed, which can firmly fix the upper mold under the fixed frame, ensuring that the upper mold does not shake or shift during the mold parting process, thus improving the mold parting accuracy. At the same time, this clamping structure is easy to operate. The installation and disassembly of the upper mold can be quickly completed by extending and retracting the drive cylinder, reducing the labor intensity of operators, and adapting to upper molds of different specifications, thus improving the versatility of the equipment.

[0021] Furthermore, the crushing mechanism includes a cutter holder with a fixing ring mounted on it. A mounting seat is provided on the outer side of the fixing ring, and the fixing ring is mounted on the frame via the mounting seat. A storage hopper is provided at the upper end of the fixing ring, and a limiting seat is clamped and fixed between the fixing ring and the cutter holder. A rotating cutter head is rotatably mounted inside the cutter holder, and a retainer is provided at the bottom end of the cutter holder. A guide rod passes through the limiting seat and connects to the rotating cutter head. The rotating cutter head and the cutter holder are provided with spiral blades. The limiting seat and the retainer are used to restrict the rotating cutter head within the cutter holder. The waste plastic is crushed by the shearing force of the blades when the rotating cutter head and the cutter holder rotate.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The fixed ring is securely mounted on the frame via the mounting base, providing stable support for the entire crushing mechanism. The storage hopper facilitates centralized loading of waste plastics, preventing scattering and improving the convenience of crushing operations. The limit seat and retainer work together to precisely confine the rotating cutter head within the cutter holder, ensuring no axial deviation or wobbling during rotation and guaranteeing the stability and precision of the blade shearing. The rotating cutter head and the spiral blades on the cutter holder work together to increase the contact area with the waste plastics, improving shearing and crushing efficiency and making the crushing of waste plastics more uniform. At the same time, the spiral structure guides the crushed plastic particles downwards, preventing blockage. The guide rod passes through the limit seat and connects to the rotating cutter head, ensuring that the rotational power of the guide rod can be accurately transmitted to the rotating cutter head, realizing synchronous linkage between lifting and crushing actions. This eliminates the need for additional crushing drive components, simplifying the equipment structure and reducing energy consumption.

[0024] Furthermore, the base also includes a connecting rod, a connecting plate, and a fifth drive cylinder mounted on the base; the bottom end of the lower mold is provided with a second fixed seat, and the clamping block is used to limit the lower mold and to cooperate with the clamping block to clamp the lower mold. The clamping block engages with the second fixed seat to limit the lower mold on the base; the second push plate is embedded in the top end of the base and is movably arranged. The bottom end of the second push plate is provided with a connecting rod, and the connecting rod passes through the base and connects to the connecting plate; the fifth drive cylinder is installed at the bottom end of the base and located on both sides of the connecting rod. An output pipe assembly is installed on the upper part of the fifth drive cylinder, and an input pipe assembly is installed on the lower part of the fifth drive cylinder; when the lifting frame moves down, the guide push rod drives the piston plate in the air cylinder to move, pressing the medium in the air cylinder into the fifth drive cylinder. The fifth drive cylinder drives the connecting plate and the connecting rod to lift the second push plate, so that the second push plate and the clamping block cooperate to clamp and fix the second fixed seat, thereby fixing the lower mold on the base.

[0025] The beneficial effects of adopting the above-mentioned further solutions are:

[0026] The clamping block engages and limits the second fixed seat of the lower mold, achieving initial positioning of the lower mold and providing a precise benchmark for subsequent clamping operations. The fifth drive cylinder is symmetrically installed on both sides of the connecting rod, providing balanced driving force. Through the connecting plate and connecting rod, it drives the second push plate to move smoothly, ensuring precise cooperation between the second push plate and the clamping block, forming a firm clamping and fixing of the second fixed seat, preventing the lower mold from shifting during the mold separation process, and ensuring mold separation accuracy. The setting of the output pipe group and the input pipe group ensures that the medium in the air cylinder can be quickly and stably input to the fifth drive cylinder, achieving rapid response of the fifth drive cylinder, thereby realizing synchronous linkage between the lowering of the lifting frame and the clamping action of the lower mold, improving work efficiency. The second push plate is embedded in the top of the base, which not only ensures the flatness of the base surface, but also restricts the movement trajectory of the second push plate, preventing it from shifting during movement, and further improving the stability of the lower mold fixing.

[0027] Furthermore, a spiral transmission mechanism is provided between the lifting frame and the guide rod. The spiral transmission mechanism includes multiple spiral grooves formed on the guide rod and sliders corresponding to the grooves set on the fixed frame. When the fixed frame moves down, the guide rod is driven to rotate through the grooves and sliders.

[0028] The beneficial effects of adopting the above-mentioned further solutions are:

[0029] The screw drive mechanism features a simple structure, precise transmission, and minimal wear. It accurately converts the linear downward movement of the fixed frame lifting frame into the rotational movement of the guide rod, eliminating the need for additional drive components for the guide rod, thus simplifying the equipment structure and reducing manufacturing costs and energy consumption. The cooperation of multiple helical grooves with corresponding sliders enhances the stability and balance of the transmission, preventing jamming or deviation during guide rod rotation and ensuring smooth, uniform rotation of the guide rod, which in turn drives the rotating cutter head to stably crush waste plastics. Furthermore, the screw drive's good self-locking property prevents accidental rotation of the guide rod when not in operation, improving the safety and reliability of the equipment.

[0030] Furthermore, the air cylinder is installed within the support of the base and the crushing mechanism.

[0031] The beneficial effects of adopting the above-mentioned further solutions are:

[0032] Concealing the air cylinder within the base and the support of the crushing mechanism effectively isolates it from external contaminants such as dust, debris, and oil, preventing them from damaging the piston plate or affecting the cylinder's sealing performance. This ensures the air cylinder's normal service life and operational stability. Simultaneously, concealed installation makes efficient use of the equipment's internal space, resulting in a more compact and aesthetically pleasing overall structure. It also prevents the air cylinder from being exposed to impacts and wear, reducing equipment failure rates and maintenance costs.

[0033] Furthermore, a guide rod is mounted on the frame via a bearing seat, and the guide rod passes through the fixed frame.

[0034] The beneficial effects of adopting the above-mentioned further solutions are:

[0035] The bearing housing reduces frictional resistance during guide rod rotation, ensuring smoother and more stable rotation, reducing component wear, and extending the service life of the guide rod. The guide rod passes through the fixed frame, enabling precise engagement with the screw drive mechanism, allowing the guide rod to rotate as the fixed frame moves downwards. It also further enhances the guide rod's limiting and guiding function on the fixed frame, preventing tilting or offset during movement, improving the stability and accuracy of the lifting frame's movement, and providing assurance for mold positioning and mold separation operations.

[0036] Furthermore, a receiving plate is also installed on one side of the base.

[0037] The beneficial effects of adopting the above-mentioned further solutions are:

[0038] The receiving plate can effectively collect waste plastic debris, mold residue, and other debris generated during the mold-breaking process, preventing debris from falling onto key components such as the guide rails, drive cylinders, and air cylinders. This prevents debris from affecting the normal operation of components or causing wear and tear, thus extending the service life of the equipment. At the same time, the centralized collection of debris facilitates subsequent cleaning by operators, reducing cleaning difficulty and labor intensity, maintaining a clean working environment for the equipment, and improving the stability of equipment operation.

[0039] Furthermore, the crushed plastic falls through the gap between the rotating cutter head and the cutter holder into the material frame set below the crushing mechanism.

[0040] The beneficial effects of adopting the above-mentioned further solutions are:

[0041] The gap between the rotating cutter head and the cutter holder provides a falling channel for the crushed plastic particles while preventing large, uncrushed pieces of waste plastic from falling, ensuring crushing quality. The material frame can collect the crushed plastic particles centrally, facilitating subsequent recycling and reuse, improving resource utilization, and meeting the industrial demand for energy conservation and environmental protection. At the same time, centralized collection prevents plastic particles from scattering into the equipment or surrounding environment, reducing cleaning workload, keeping the equipment and working environment clean, and preventing plastic particles from affecting the operation of key equipment components.

[0042] As can be seen, the multi-axis collaborative control high-precision vertical mold parting machine provided by this invention has the following beneficial effects:

[0043] The equipment uses a drive pump to power the first and second drive cylinders, which work together to smoothly raise and lower the lifting frame. Simultaneously, as the lifting frame descends, the fifth drive cylinder is triggered by the cooperation of a guide rod and an air cylinder, automatically clamping the lower mold. The guide rod, in conjunction with a screw transmission mechanism, synchronously drives the rotating cutter head to complete the waste plastic crushing operation. This multi-action coordinated design avoids the time losses caused by individual operations, integrating mold clamping, waste plastic crushing, and lifting frame movements. It eliminates the need for separate drive mechanisms to control each action, simplifying the equipment structure, reducing manufacturing costs and maintenance difficulty, effectively shortening the single-operation cycle time, and improving the overall operating efficiency of the equipment. It is suitable for large-volume mold-splitting operations.

[0044] The lower mold is initially positioned by clamping blocks, and then clamped and fixed by the second push plate in conjunction with the clamping blocks. The upper mold is clamped and fixed by the interaction of the claw hooks and the first push plate. This double clamping structure ensures that the mold will not shift or shake during the mold parting process, guaranteeing the flatness of the parting surface and the mold parting accuracy. At the same time, the guide rod and guide push rod not only provide the driving linkage function, but also play a limiting and guiding role during the movement of the fixed frame. Together with the guide rails on both sides of the frame and the pulleys on the lifting frame, a multi-limiting and guiding system is formed, which effectively avoids tilting or shifting during the movement of the lifting frame. This further improves the accuracy of mold clamping and parting, reduces parting errors, ensures the quality of the mold after parting, and reduces problems such as mold damage and product defects caused by insufficient parting accuracy.

[0045] The linear motion of the lifting frame is converted into the rotational motion of the guide rod by the screw transmission mechanism, which in turn drives the rotating cutter head to cooperate with the cutter holder to complete the crushing of waste plastic. There is no need to set up a separate drive component for the crushing mechanism, which saves equipment space, reduces energy consumption, and realizes the simultaneous operation of mold splitting and waste plastic crushing. It avoids the accumulation of waste plastic generated during the mold splitting process from affecting the operation of the equipment. At the same time, the crushed plastic can be collected in a material frame to realize the recycling and reuse of resources, which meets the needs of energy-saving and environmentally friendly industrial development.

[0046] The upper mold is quickly clamped and fixed by the cooperation of the claw hook and the first push plate, while the lower mold is quickly positioned and clamped by the synergistic action of the clamping block and the second push plate. The clamping process does not require complicated manual operation, which makes it easy for operators to quickly complete the installation and disassembly of the mold and reduce the labor intensity of the operators. At the same time, this clamping structure can be adapted to molds of different specifications and models. Only by adjusting the position of the clamping block and the push plate can different molds be clamped and fixed, which improves the versatility of the equipment, expands the scope of application of the equipment, and reduces the equipment modification costs caused by replacing molds.

[0047] The limit seat and retainer in the crushing mechanism can firmly confine the rotating cutter head within the cutter holder, preventing it from shifting or loosening during rotation and extending the service life of the crushing components. The air cylinder is installed in the base and the support of the crushing mechanism, effectively preventing external debris and dust from entering the air cylinder and ensuring its sealing performance and service life. The material receiving plate on one side of the base can effectively receive materials and debris generated during the mold separation process, preventing materials from scattering and causing wear on equipment components. It also facilitates subsequent cleaning, further improving the stability and service life of the equipment and reducing maintenance and operating costs. Attached Figure Description

[0061] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Please see Figures 1 to 9 As shown, the embodiments provided by the present invention are as follows:

[0063] Example 1

[0064] A multi-axis collaborative control high-precision vertical mold parting machine includes:

[0065] A frame 1 is provided, a lifting frame 2 is slidably mounted on the frame 1, and a base 3 and a crushing mechanism 4 are mounted on the frame 1 below the lifting frame 2.

[0066] The lifting frame 2 is used to install the upper mold 203;

[0067] The base 3 includes a base 301 and a clamping block 304 and a second push plate 302 disposed thereon;

[0068] The lifting frame 2 is connected to a drive device that drives its lifting and lowering;

[0069] The lifting frame 2 is equipped with a guide rod 102, which is connected to the rotating cutter head 404 of the crushing mechanism 4. When the lifting frame 2 descends, the guide rod 102 is driven to rotate, which in turn drives the rotating cutter head 404 to rotate to crush the waste plastic.

[0070] The lifting frame 2 is equipped with a guide push rod 101, and the frame 1 is equipped with an air cylinder 104. The end of the guide push rod 101 extends into the air cylinder 104 and is equipped with a piston plate. The air cylinder 104 is connected to the fifth drive cylinder 308 on the base 3 through a pipeline. The fifth drive cylinder 308 is used to drive the second push plate 302 to move. When the lifting frame 2 descends, the guide push rod 101 drives the medium in the air cylinder 104 to enter the fifth drive cylinder 308, so that the second push plate 302 moves to cooperate with the clamping block 304 to clamp the lower mold 305.

[0071] Example 2

[0072] To further optimize the power output stability of the drive unit, simplify the load-bearing and assembly structure of the lifting frame, achieve rapid assembly and disassembly and precise fixation of the upper mold, and ensure coordinated operation between the lifting action and the upper mold fixing action, for example, such as Figures 1 to 9 As shown, the present invention also includes:

[0073] The drive unit includes a first drive cylinder 201 and a second drive cylinder 202 mounted on the frame 1, and a drive pump 103 that drives the first drive cylinder 201 and the second drive cylinder 202. The output ends of the first drive cylinder 201 and the second drive cylinder 202 are connected and fixed to the lifting frame 2. Guide rails 105 are provided on both sides of the frame 1, and pulleys are provided on both sides of the lifting frame 2. The lifting frame 2 descends smoothly through the cooperation of the pulleys and the guide rails 105. Through the cooperation of the first drive cylinder 201, the second drive cylinder 202 and the drive pump 103, the multi-axis coordinated drive of the lifting frame 2 is realized, which is more efficient than a single-axis drive. The drive cylinder structure provides a more balanced and stable driving force, preventing tilting and jamming during the lifting process of the lifting frame 2, and ensuring the smoothness and synchronization of the lifting action. The guide rails 105 on both sides of the frame 1 and the pulleys on both sides of the lifting frame 2 cooperate to form a precise guiding structure, further reducing the frictional resistance during the movement of the lifting frame 2, ensuring that the lifting frame 2 rises and falls smoothly along the preset trajectory, laying the foundation for subsequent precise positioning, clamping and mold separation operations of the mold, while reducing component wear, extending the service life of the drive device and the lifting frame 2, and improving the stability and reliability of the equipment operation.

[0074] The lifting frame 2 includes a fixed frame 204, with a connector 205 mounted on the lower surface of the fixed frame 204, and a guide push rod 101 mounted on the connector 205. The output ends of the first drive cylinder 201 and the second drive cylinder 202 are connected and fixed to the fixed frame 204. A third drive cylinder 207 and a fourth drive cylinder 208 are mounted on the fixed frame 204. The output end of the third drive cylinder 207 passes through the fixed frame 204 and is equipped with a claw hook 210. The output end of the fourth drive cylinder 208 passes through the fixed frame 204. 4. A first push plate 209 is installed; the top of the upper mold 203 is provided with a first fixed seat 206. The upper mold 203 is installed below the fixed frame 204 through the cooperation of the claw hook 210 and the first fixed seat 206. At the same time, the fourth drive cylinder 208 drives the first push plate 209 to press the first fixed seat 206. The interaction between the first push plate 209 and the claw hook 210 clamps and fixes the first fixed seat 206, thereby installing the upper mold 203 on the fixed frame 204. The fixed frame 204 As the core load-bearing component of the lifting frame 2, it provides a stable installation foundation for each drive cylinder, guide push rod 101, and upper mold 203. The connector 205 makes the guide push rod 101 more securely installed, preventing it from loosening or shifting during lifting, and ensuring the coordinated linkage effect between the guide push rod 101 and the air cylinder 104. The third drive cylinder 207 and the fourth drive cylinder 208 drive the claw hook 210 and the first push plate 209 to move respectively. Through the snap-fit ​​cooperation between the claw hook 210 and the first fixed seat 206, and the pressing action of the first push plate 209 on the first fixed seat 206, a double clamping and fixing structure is formed, which can firmly fix the upper mold 203 under the fixed frame 204, ensuring that the upper mold 203 does not shake or shift during the mold splitting process, thus improving the mold splitting accuracy. At the same time, this clamping structure is easy to operate. The installation and disassembly of the upper mold 203 can be quickly completed by the extension and retraction of the drive cylinder, reducing the labor intensity of the operator, and adapting to different specifications of upper molds 203, improving the versatility of the equipment.

[0075] Example 3

[0076] To achieve synchronized lifting and crushing of waste plastics, simplify the drive structure of the crushing mechanism, improve the efficiency and uniformity of waste plastic crushing, and ensure the installation stability and operational reliability of the crushing mechanism, for example, such as Figures 1 to 9 As shown, the present invention also includes:

[0077] The crushing mechanism 4 includes a cutter holder 405, on which a retaining ring 401 is mounted. A mounting seat 406 is provided on the outer side of the retaining ring 401. The retaining ring 401 is mounted on the frame 1 through the mounting seat 406. A storage hopper 407 is provided at the upper end of the retaining ring 401, and a limiting seat 402 is clamped and fixed between the retaining ring 401 and the cutter holder 405. A rotating cutter head 404 is rotatably mounted inside the cutter holder 405, and a retainer 403 is provided at the bottom end of the cutter holder 405. The guide rod 102 passes through the limiting seat 402 and connects to the rotating cutter head 404. The rotating cutter head 404 and the cutter holder 405 are provided with spiral blades. The limiting seat 402 and the retainer 403 are used to restrict the rotating cutter head 404 within the cutter holder 405. The waste plastic is crushed by the shearing force of the blades when the rotating cutter head 404 and the cutter holder 405 rotate. The fixing ring 401 is firmly installed on the frame 1 through the mounting seat 406, providing stability for the entire crushing mechanism 4. The storage hopper 407 provides stable support and facilitates centralized loading of waste plastics, preventing them from scattering and improving the convenience of the crushing operation. The limit seat 402 and the retainer 403 work together to precisely confine the rotating cutter head 404 within the cutter holder 405, ensuring that the rotating cutter head 404 does not shift axially or wobble during rotation, thus guaranteeing the stability and accuracy of the blade shearing. The rotating cutter head 404 and the spiral blades on the cutter holder 405 work together to increase the contact area with the waste plastics, improving shearing and crushing efficiency and making the waste plastics crushed more evenly. At the same time, the spiral structure can guide the crushed plastic particles to slide downwards, avoiding blockage. The guide rod 102 passes through the limit seat 402 and connects to the rotating cutter head 404, ensuring that the rotational power of the guide rod 102 can be accurately transmitted to the rotating cutter head 404, realizing the synchronous linkage of lifting and crushing actions. This eliminates the need for additional crushing drive components, simplifying the equipment structure and reducing energy consumption.

[0078] The crushed plastic falls through the gap between the rotating cutter head 404 and the cutter holder 405 into the material frame located below the crushing mechanism 4. The gap between the rotating cutter head 404 and the cutter holder 405 provides a falling channel for the crushed plastic particles while preventing large pieces of uncrushed waste plastic from falling, ensuring crushing quality. The material frame can collect the crushed plastic particles centrally, facilitating subsequent recycling and reuse, improving resource utilization, and meeting the industrial requirements of energy conservation and environmental protection. At the same time, centralized collection can prevent plastic particles from scattering into the equipment or the surrounding environment, reducing cleaning workload, keeping the equipment and working environment clean, and preventing plastic particles from affecting the operation of key components of the equipment.

[0079] Example 4

[0080] To achieve automatic and precise clamping and rapid positioning of the lower mold, ensuring its stability during mold parting, and simultaneously enabling coordinated control of lifting and clamping actions to improve the ease of assembly and disassembly of the lower mold, for example, such as... Figures 1 to 9 As shown, the present invention also includes:

[0081] The base 3 also includes a connecting rod 306, a connecting plate 307, and a fifth drive cylinder 308 disposed on the base 301; the bottom end of the lower mold 305 is provided with a second fixed seat 311, and a clamping block 304 is used to limit the lower mold 305, and is used to cooperate with the clamping block 304 to clamp the lower mold 305. The clamping block 304 engages with the second fixed seat 311 to limit the lower mold 305 on the base 301; the second push plate 302 is embedded in the top end of the base 301, and the second push plate 302 is movably disposed. The bottom end of the second push plate 302 is provided with a connecting rod 306, and the connecting rod 306 passes through the base 301 and is connected to the connecting plate 307; the fifth drive cylinder 308 is installed at the bottom of the base 301 and located on both sides of the connecting rod 306. An output pipe assembly 310 is installed on the upper part of the fifth drive cylinder 308, and a pressure relief valve is installed on the output pipe assembly 310 to discharge excess air pressure delivered from the air cylinder 104 to the fifth drive cylinder 308, ensuring stable internal pressure in the fifth drive cylinder 308. An input pipe assembly 309 is installed on the lower part of the fifth drive cylinder 308. When the lifting frame 2 moves downward, the guide push rod 101 drives the piston plate inside the air cylinder 104 to move, pressing the medium inside the air cylinder 104 into the fifth drive cylinder 308. The fifth drive cylinder 308 then drives the connecting plate 307 and the connecting rod 306 to... The second push plate 302 lifts up, causing it to cooperate with the clamping block 304 to clamp and fix the second fixed seat 311, thereby fixing the lower mold 305 onto the base 301. The clamping block 304 engages and limits the second fixed seat 311 of the lower mold 305, achieving initial positioning of the lower mold 305 and providing a precise reference for subsequent clamping operations. The fifth drive cylinder 308 is symmetrically installed on both sides of the connecting rod 306, providing balanced driving force. Through the connecting plate 307 and the connecting rod 306, it drives the second push plate 302 to move smoothly, ensuring precise cooperation between the second push plate 302 and the clamping block 304, forming a firm support for the second fixed seat 311. The clamping and fixing mechanism prevents the lower mold 305 from shifting during the mold splitting process, ensuring mold splitting accuracy. The output pipe group 310 and the input pipe group 309 ensure that the medium in the air cylinder 104 can be quickly and stably input to the fifth drive cylinder 308, realizing the rapid response of the fifth drive cylinder 308. This enables the synchronous linkage between the downward movement of the lifting frame 2 and the clamping action of the lower mold 305, improving work efficiency. The second push plate 302 is embedded in the top of the base 301, which not only ensures the flatness of the base 301 surface but also restricts the movement trajectory of the second push plate 302, preventing it from shifting during movement and further improving the stability of the lower mold 305.

[0082] A receiving plate 303 is also installed on one side of the base 301. The receiving plate can effectively receive waste plastic debris, mold residue and other debris generated during the mold parting process, preventing debris from falling onto key components such as the guide rail 105, drive cylinder and air cylinder 104 of the equipment, preventing debris from affecting the normal operation of the components or causing wear and tear, and extending the service life of the equipment. At the same time, the centralized collection of debris makes it easier for operators to clean up later, reducing the difficulty and labor intensity of cleaning, keeping the working environment of the equipment clean and improving the stability of equipment operation.

[0083] Example 5

[0084] To achieve precise conversion between the linear motion of the lifting frame and the rotational motion of the guide rod, simplify the drive and installation structure of the guide rod, improve its operational stability and self-locking reliability, and ensure the installation protection of the air cylinder and the limiting function of the guide rod, for example, such as Figures 1 to 9 As shown, the present invention also includes:

[0085] A helical transmission mechanism is provided between the lifting frame 2 and the guide rod 102. The helical transmission mechanism includes multiple helical grooves on the guide rod 102 and corresponding sliders on the fixed frame 204. When the fixed frame 204 moves downward, the guide rod 102 is driven to rotate through the grooves and sliders. The helical transmission mechanism has a simple structure, precise transmission, and low wear. It can accurately convert the linear downward movement of the fixed frame 204 and the lifting frame 2 into the rotational movement of the guide rod 102 without the need for additional drive components for the guide rod 102, simplifying the equipment structure and reducing manufacturing costs and energy consumption. The cooperation between the multiple helical grooves and the corresponding sliders can improve the stability and balance of the transmission, avoid jamming or deviation during the rotation of the guide rod 102, and ensure that the guide rod 102 can rotate smoothly and at a uniform speed, thereby driving the rotating cutter head 404 to stably crush waste plastics. At the same time, the helical transmission has good self-locking properties, which can prevent the guide rod 102 from rotating unexpectedly when it is not in operation, improving the safety and reliability of the equipment operation.

[0086] The air cylinder 104 is installed inside the support of the base 3 and the crushing mechanism 4. Concealing the air cylinder 104 inside the support of the base 3 and the crushing mechanism 4 can effectively isolate external dust, debris, oil and other contaminants, preventing contaminants from entering the air cylinder 104 and damaging the piston plate or affecting the sealing performance of the air cylinder 104, thus ensuring the normal service life and working stability of the air cylinder 104. At the same time, the concealed installation can make reasonable use of the internal space of the equipment, making the overall structure of the equipment more compact and beautiful, avoiding the air cylinder 104 from being exposed to collisions and wear, reducing the failure rate of the equipment and reducing maintenance costs.

[0087] A guide rod 102 is mounted on the frame 1 via a bearing seat. The guide rod 102 passes through the fixed frame 204. The bearing seat reduces the frictional resistance during the rotation of the guide rod 102, ensuring smoother and more stable rotation, reducing component wear, and extending the service life of the guide rod 102. The guide rod 102 passing through the fixed frame 204 enables precise coordination of the screw drive mechanism, driving the guide rod 102 to rotate as the fixed frame 204 moves downward. It also further enhances the limiting and guiding function of the guide rod 102 on the fixed frame 204, preventing tilting or deviation during the movement of the fixed frame 204, improving the stability and accuracy of the movement of the lifting frame 2, and providing a guarantee for mold positioning and mold splitting operations.

[0088] Working principle:

[0089] Before starting the equipment, the closed mold is placed on the base 3 to complete the initial placement and positioning of the mold, preparing for subsequent fixing and mold separation operations. At this time, the fixing seat at the bottom of the lower mold 305 is initially aligned with the clamping block 304 on the base 3. The clamping block 304 plays an initial limiting role on the lower mold 305 to prevent the mold from shifting.

[0090] After the equipment is started, the drive unit begins to work. The drive pump 103 provides power to the first drive cylinder 201 and the second drive cylinder 202. The output ends of the first drive cylinder 201 and the second drive cylinder 202 drive the lifting frame 2 to descend smoothly along the guide rails 105 on both sides of the frame 1. The pulleys on both sides of the lifting frame 2 cooperate with the guide rails 105 to effectively ensure the stability and accuracy of the lifting frame 2 during descent, realizing multi-axis coordinated drive lifting control. Among them, the guide rod 102 and the guide push rod 101, in addition to the above functions, also play a role in limiting and guiding the movement of the fixed frame 204, further improving the stability and accuracy of the movement of the fixed frame 204 and the lifting frame 2, avoiding deviation during movement, and ensuring the mold parting accuracy. During the downward movement of the lifting frame 2, the fixing action of the base 3 on the lower mold 305 is triggered simultaneously: the guide push rod 101 on the lifting frame 2 moves down together with the lifting frame 2, the end of the guide push rod 101 extends into the air cylinder 104 and drives the piston plate to move, pressing the medium in the air cylinder 104 into the fifth drive cylinder 308 on the base 3. After receiving the medium, the fifth drive cylinder 308 starts, driving the connecting plate 307 and the connecting rod 306 to move, thereby lifting the second push plate 302 embedded at the top of the base 301. The second push plate 302 cooperates with the clamping block 304 on the base 3 to clamp and fix the fixing seat at the bottom of the lower mold 305, thereby stabilizing the lower mold 305 on the base 301, realizing the coordinated linkage between the lifting action and the clamping action of the lower mold 305, and ensuring the positioning accuracy of the mold during the mold separation process.

[0091] Once the lifting frame 2 has descended to its designated position, it begins to secure the upper mold 203. The third drive cylinder 207 on the lifting frame 2 drives the claw hook 210, and the fourth drive cylinder 208 drives the first push plate 209. The claw hook 210 engages with the fixed seat at the top of the upper mold 203, while the first push plate 209 presses against the fixed seat. Through their interaction, the upper mold 203 is securely installed below the fixed frame 204 of the lifting frame 2, completing the securing operation of the upper mold 203. During this process, the lifting frame 2 and the guide rod 102 are connected by a helical transmission mechanism. This mechanism consists of a helical groove on the guide rod 102 and a slider on the fixed frame 204. When the lifting frame 2 moves the fixed frame 204 downwards, the slider slides within the helical groove of the guide rod 102, thereby driving the guide rod 102 to rotate around its own axis. The guide rod 102 passes through the limiting seat 402 of the crushing mechanism 4 and connects to the rotating cutter head 404. When the guide rod 102 rotates, it drives the rotating cutter head 404 to rotate synchronously within the cutter holder 405. Both the rotating cutter head 404 and the cutter holder 405 are equipped with spiral blades. Through the relative rotation between the rotating cutter head 404 and the cutter holder 405, the shearing force of the blades is used to crush the waste plastic fed into the storage hopper 407, realizing the coordinated operation of the lifting action and the waste plastic crushing action, thereby improving the operating efficiency of the equipment. The limiting seat 402 and the retainer 403 restrict the rotating cutter head 404 within the cutter holder 405, ensuring the stability of the rotating cutter head 404 during rotation and preventing blade deviation from affecting the crushing effect.

[0092] After the upper mold 203 is fixed, the lifting frame 2 begins to reset. During the reset process, the guide push rod 101 rises with the lifting frame 2, the medium in the air cylinder 104 flows back, and the fifth drive cylinder 308 resets. However, the lower mold 305 remains clamped and fixed to ensure the stability of the mold splitting operation. After the lifting frame 2 is reset, the equipment begins the mold splitting operation to complete the mold splitting process. The crushed plastic particles fall through the gap between the rotating cutter head 404 and the cutter holder 405, and finally fall into the material frame set below the crushing mechanism 4, completing the collection of waste plastic. The receiving plate installed on one side of the base 3 can receive the materials or debris generated during the mold splitting process to prevent the materials from scattering and affecting the normal operation of the equipment. After the mold splitting operation is completed, the upper mold 203 can be released by resetting the third drive cylinder 207 and the fourth drive cylinder 208. At the same time, the fifth drive cylinder 308 is fully reset, driving the second push plate 302 to move down, releasing the clamp on the lower mold 305, and taking out the mold after mold splitting, completing one complete operation cycle.
