Description

Technical Field

[0001] This invention relates to the field of die-casting equipment technology, and in particular to a die-casting machine for the production and processing of automotive cylinder seals. Background Technology

[0002] A die-casting machine for manufacturing automotive cylinder seals is a specialized hydraulic molding equipment for producing rubber seals for automotive cylinders. This equipment injects molten rubber or polyurethane material under high pressure and high speed into a precisely designed mold cavity, where it undergoes a vulcanization and cross-linking reaction before solidification to obtain the desired cylinder seal product.

[0003] A patent with publication number CN120619314B discloses an energy-saving die-casting machine, including a mold-locking column and a barrel. The barrel is mounted on the mold-locking column, and a pressure injection chamber is coaxially formed in the middle of the barrel. An injection assembly is installed inside the pressure injection chamber, which can slide within the pressure injection chamber to inject molten metal into the mold. A gate connected to the pressure injection chamber is formed on the barrel, and a liner is engaged inside the gate. Both ends of the liner are provided with annular portions coaxially sleeved on the outside of the barrel. During molten metal pouring, the liner protects the gate, and the annular portions block the molten metal at both ends of the gate, restricting the molten metal to slide only in the area between the annular portions. When the injection rod pushes the hammer to inject molten metal, an arc plate rotates around the barrel between the two annular portions, collecting and pushing the sliding molten metal towards the gate. However, due to the relatively simple mold, the device can only produce seals of fixed sizes, resulting in low production efficiency.

[0004] Therefore, it is necessary to provide a new die-casting machine for the production and processing of automotive cylinder seals to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a die-casting machine for the production and processing of automotive cylinder seals.

[0006] The die-casting machine for producing and processing automotive cylinder seals provided by the present invention includes a die-casting machine body, a die-casting assembly movably connected inside the die-casting machine body, a plurality of limiting components detachably connected inside the die-casting assembly, and a driving component fixedly connected to the outer wall of the limiting component. The limiting component includes a mounting shell, which is fixedly connected to the bottom wall of the die-casting component. A movable shell is rotatably connected to the bottom wall of the mounting shell. Multiple receiving plates are fixedly connected to the inner side wall of the movable shell. A turntable is fixedly connected to the end of the multiple receiving plates away from the movable shell. Multiple connecting rods are rotatably connected to the bottom wall of the turntable. A limiting plate is rotatably connected to the end of each of the multiple connecting rods away from the turntable. Multiple sliding grooves are opened in the turntable. Fixed posts are slidably connected in each of the multiple sliding grooves. A positioning plate is fixedly connected to the bottom end of each of the multiple fixed posts. The top end of each of the multiple fixed posts is fixedly connected to the mounting shell. Multiple limiting posts are fixedly connected to the upper surface of the positioning plate. Each of the multiple limiting posts corresponds to a multiple limiting plate, and the limiting post passes through the corresponding limiting plate.

[0007] Preferably, the drive assembly includes a worm gear, the inner wall of which is fixedly connected to the outer wall of the movable housing, and a worm meshing with one side of the worm gear, the worm penetrating the side wall of the die-casting assembly.

[0008] Preferably, the bottom wall of the mounting shell has an arc-shaped groove, and a guide rod is fixedly connected in the arc-shaped groove. The guide rod is arc-shaped, and a sliding plate is slidably connected to the outer wall of the guide rod. The sliding plate is fixedly connected to the top wall of the movable shell.

[0009] Preferably, the die-casting assembly includes an electric cylinder, the output end of which is fixedly connected to a mounting plate. The mounting plate has multiple through slots, which are arranged intersectingly with multiple limiting components.

[0010] Preferably, the die-casting machine body has multiple storage compartments detachably connected to it, the multiple storage compartments are arranged opposite to multiple through slots, and the bottom wall of each storage compartment is provided with a discharge port. The die-casting machine body is movably connected to a transport component.

[0011] Preferably, the transport component includes two synchronous pulleys, with a synchronous belt nested on the outer walls of the two synchronous pulleys. A drive motor is detachably connected to the inner cavity of the die-casting machine body, and the output end of the drive motor is fixedly connected to any one of the synchronous pulleys. Multiple push bars are fixedly connected to the outer wall of the synchronous belt.

[0012] Compared with related technologies, the die-casting machine for manufacturing automotive cylinder seals provided by this invention has the following advantages: 1. By designing the limiting components within the die-casting assembly as multiple independent and detachable modules, and equipping them with multiple storage compartments for molds of different specifications, a single machine can simultaneously accommodate sealing molds of various sizes or shapes. During production, the control system can automatically retrieve the required molds from the corresponding storage compartments via the transport component according to task requirements, quickly completing the mold replacement for different limiting components. This design breaks the limitation of traditional single mold heads that can only produce products of fixed specifications, realizing flexible production of small batches and multiple varieties, significantly reducing mold change downtime, thereby improving the overall utilization rate and production efficiency of the equipment; 2. The limiting assembly utilizes a multi-link linkage structure composed of a turntable, connecting rods, and multiple limiting plates to precisely convert the rotational motion of the movable shell into the synchronous radial motion of multiple clamping jaws. Because all limiting plates swing simultaneously around the limiting post, the mold head automatically centers itself when clamped, always remaining coaxial with the axis of the die-casting assembly. This high-precision centering and clamping method avoids the problem of off-center loading caused by manual adjustment or unilateral clamping, ensuring the quality of the die-cast product and extending the service life of the mold and equipment. 3. On the one hand, the drive assembly adopts a worm gear transmission with self-locking characteristics. The operator only needs to slightly rotate the worm gear outside the equipment to control the clamping and release of the mold. This not only saves effort and has high adjustment accuracy, but also ensures the stability and reliability of the clamping state during the die casting process by the self-locking function of the worm gear, preventing loosening caused by vibration. On the other hand, the arc-shaped groove and guide rod structure at the bottom of the mounting shell provide precise guidance and limit for the rotation of the movable shell, effectively preventing radial sway and excessive rotation during movement, improving the smoothness of the mechanism's movement, and distributing the force on the transmission components, thereby reducing the equipment's failure rate and long-term maintenance costs.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] In specific implementation, a die-casting machine for manufacturing automotive cylinder seals has the following structure: Figure 1 — Figure 5 As shown, the die casting mold with replaceable sealing mold includes a die casting machine body 1, a die casting assembly 2 is movably connected inside the die casting machine body 1, a plurality of limiting assemblies 6 are detachably connected inside the die casting assembly 2, and a drive assembly 7 is fixedly connected to the outer wall of the limiting assembly 6. It should be noted that this die-casting mold achieves rapid replacement and multi-functional processing of the die-casting head through modular design. The die-casting machine body 1 serves as the basic load-bearing structure, providing stable motion guidance and power support for the die-casting component 2. The die-casting component 2 reciprocates and lifts within the die-casting machine body 1 to complete the die-casting process of the workpiece. Multiple limit components 6 are independently installed inside the die-casting component 2, forming an independently controllable clamping unit. Each limit component 6 can be disassembled and replaced individually, facilitating maintenance and upgrades. The drive component 7 serves as the power input for the limit components 6, and through external control, it realizes the mechanical action conversion within the limit components 6, thereby completing the clamping or release of the sealing mold. The entire system improves the reliability and flexibility of the equipment through decentralized control, avoiding the problems of difficult replacement and high maintenance costs associated with traditional integrated mold heads.

[0018] The limiting component 6 includes a mounting shell 61, which is fixedly connected to the bottom wall of the die-casting component 2. A movable shell 62 is rotatably connected to the bottom wall of the mounting shell 61. Multiple receiving plates 63 are fixedly connected to the inner side wall of the movable shell 62. A turntable 64 is fixedly connected to the end of the multiple receiving plates 63 away from the movable shell 62. Multiple connecting rods 65 are rotatably connected to the bottom wall of the turntable 64. A limiting plate 66 is rotatably connected to the end of each of the multiple connecting rods 65 away from the turntable 64. Multiple sliding grooves 67 are opened in the turntable 64. Fixed posts 68 are slidably connected in each of the multiple sliding grooves 67. A positioning plate 69 is fixedly connected to the bottom end of the multiple fixed posts 68. The top end of the multiple fixed posts 68 is fixedly connected to the mounting shell 61. Multiple limiting posts 610 are fixedly connected to the upper surface of the positioning plate 69. The multiple limiting posts 610 correspond one-to-one with the multiple limiting plates 66, and the limiting posts 610 penetrate through the corresponding limiting plates 66. It should be noted that the limiting component 6 adopts a multi-link linkage structure to achieve concentric clamping of the sealing mold. The mounting shell 61 serves as a fixed base, ensuring a reliable connection between the entire limiting component 6 and the die-casting component 2. The movable shell 62 serves as a rotary actuator, and its rotational motion is transmitted to the turntable 64 through the receiving plate 63, forming a uniform torque distribution. The number and distribution of the receiving plates 63 are optimized to ensure uniform force on the turntable 64 and avoid jamming or wear caused by uneven load. The rotational motion of the turntable 64 is converted into the swinging motion of the limiting plate 66 through the connecting rod 65. Both ends of the connecting rod 65 adopt a rotating connection method, which reduces frictional resistance and improves motion sensitivity. The limiting plate 66 surrounds the limiting... When the positioning post 610 rotates, the limiting post 610 acts as a rotation fulcrum and simultaneously serves as a guide and positioning point, ensuring the accuracy of the movement trajectory of the limiting plate 66. The sliding fit between the slide groove 67 and the fixed post 68 provides constraint and guidance for the rotation of the turntable 64, limiting the degree of freedom of the turntable 64 so that it can only rotate around the axis and cannot undergo radial displacement. The positioning plate 69 is connected to the mounting shell 61 through the fixed post 68, forming a stable support structure and ensuring the positional accuracy of the limiting post 610. The entire mechanism converts the rotational motion into the synchronous radial motion of multiple clamping claws, realizing automatic centering and clamping of the sealing mold, and ensuring the coaxiality of the mold head and the die-casting component 2 without manual adjustment.

[0019] The drive assembly 7 includes a worm gear 71, the inner wall of which is fixedly connected to the outer wall of the movable housing 62, and a worm 72 meshing on one side of the worm gear 71, the worm 72 penetrating the side wall of the die-casting assembly 2. It should be noted that the drive assembly 7 adopts a worm gear transmission method, which has a self-locking characteristic and can ensure the stability of the limit assembly 6 in the clamped state. The worm gear 71 is fixedly connected to the outer wall of the movable housing 62, directly transmitting the rotational power to the movable housing 62, reducing intermediate transmission links and improving transmission efficiency. The worm 72 extends through the side wall of the die-casting assembly 2 to the outside, allowing the operator to control the movement of the limit assembly 6 from outside the equipment by rotating the worm 72, improving operational safety and convenience. The worm gear transmission pair has a large transmission ratio, requiring only a slight rotation during operation. The movable worm gear 72 enables large-angle rotation of the movable housing 62, improving adjustment accuracy and control sensitivity. At the same time, the self-locking characteristic of the worm gear ensures that the movable housing 62 will not rotate on its own due to external force or vibration after it stops rotating, ensuring the clamping reliability of the mold head during the die casting process. The two ends of the worm gear 72 are supported on the side wall of the die casting component 2 by bearings, reducing rotational resistance and extending service life. In addition, the worm gears 72 of multiple limit components 6 can be operated independently, realizing independent control of each limit component 6, which provides convenience for rapid adjustment when processing different products.

[0020] It should be noted that when the sealing mold needs to be replaced, first rotate the worm 72, which drives the worm wheel 71 to rotate. The worm wheel 71 drives the movable housing 62 to rotate, and the movable housing 62 drives the turntable 64 to rotate through the receiving plate 63. Since one end of the limiting plate 66 is fixed, the limiting plate 66 rotates around the limiting post 610 under the drive of the turntable 64 and the connecting rod 65, thereby opening multiple limiting plates 66. Then, the sealing mold to be replaced can be installed in the movable housing 62. After that, rotating the worm 72 in the opposite direction will restore the device to its original state. Since multiple limiting plates 66 rotate at the same time, the size between multiple limiting plates 66 can be adjusted, which facilitates the replacement of sealing molds of different sizes. At the same time, since multiple limiting components 6 are set independently, the sealing molds in multiple limiting components 6 can be replaced with sealing molds of different sizes as needed during the use of the equipment, making the device more flexible and capable of producing multiple molds of different sizes or shapes at the same time. It should be noted that this working process demonstrates the efficiency and adaptability of the device in mold head replacement. During operation, the rotation of the worm 72 amplifies the torque and reduces the speed through the worm wheel 71, making the rotation of the movable shell 62 smooth and controllable, avoiding impact and vibration. The receiving plate 63 synchronously transmits the rotation of the movable shell 62 to the turntable 64, ensuring the consistency of movement of multiple connecting rods 65. When the turntable 64 rotates, the connecting rods 65 pull the limiting plate 66 to swing around the limiting post 610. The end of the limiting plate 66 gradually moves away from the central axis, forming an open clamping space. This synchronous movement ensures that the multiple limiting plates 66 are always evenly open, maintaining the centering characteristics and facilitating rapid mold head replacement. After the mold head is inserted and installed in place, the worm gear 72 is rotated in the opposite direction, and the limiting plate 66 retracts simultaneously, applying clamping force evenly from multiple directions to firmly hold the mold head. Since the clamping range of the limiting plate 66 is continuously adjustable, the device can adapt to mold heads of various diameters or shapes without the need to replace the grippers or adjust the shims, greatly shortening the mold change time. The advantage of independently setting multiple limiting components 6 is that operators can configure different specifications of mold heads for different limiting components 6 according to the production plan. During the production process, the continuous production of multiple products can be achieved by switching between different limiting components 6, avoiding the tedious operation of frequently changing mold heads and improving equipment utilization and production efficiency.

[0021] An arc-shaped groove 8 is provided on the bottom wall of the mounting shell 61. A guide rod 9 is fixedly connected in the arc-shaped groove 8. The guide rod 9 is arc-shaped and a sliding plate 10 is slidably connected to the outer wall of the guide rod 9. The sliding plate 10 is fixedly connected to the top wall of the movable shell 62. It should be noted that the guiding mechanism consisting of the arc-shaped groove 8 and the guide rod 9 plays a role in precisely limiting the rotation of the movable shell 62 and smoothing its movement. The arc-shaped groove 8 is centered on the rotation axis of the movable shell 62, ensuring that the trajectory of the sliding plate 10 within the groove perfectly matches the theoretical rotation trajectory of the movable shell 62. The guide rod 9 is fixed within the arc-shaped groove 8, serving as the sliding track for the sliding plate 10. Its arc-shaped design matches the movement trajectory of the movable shell 62. The sliding plate 10 and the guide rod 9 are in a sliding fit, with the gap controlled within a reasonable range, ensuring smooth movement while eliminating radial wobble. When the movable shell 62... During rotation, the sliding plate 10 slides along the guide rod 9. The guide rod 9 provides both support and guidance for the sliding plate 10, preventing the movable shell 62 from tilting or shifting due to gravity or external forces. This guiding structure not only improves the motion accuracy of the movable shell 62 but also shares the force at the connection between the worm gear 71 and the movable shell 62, extending the service life of the connection. In addition, the cooperation between the arc groove 8 and the guide rod 9 also serves as a limiting function. By controlling the arc length of the arc groove 8, the maximum rotation angle of the movable shell 62 can be limited, preventing excessive rotation from causing interference or damage to the internal mechanism, thus improving the safety and reliability of the equipment operation.

[0022] The die-casting assembly 2 includes an electric cylinder 21. The output end of the electric cylinder 21 is fixedly connected to a mounting plate 22. The mounting plate 22 has multiple through slots 23, which are arranged intersectingly with multiple limiting assemblies 6. It should be noted that the die-casting component 2 uses an electric cylinder 21 as its power source. Compared with traditional hydraulic or pneumatic methods, it has advantages such as high control precision, fast response speed, energy saving and environmental protection. The electric cylinder 21 converts the motion of the rotary motor into linear motion through a ball screw, which can accurately control the stroke position and movement speed of the mounting plate 22 to meet the pressure and speed requirements of different die-casting processes. As the bearing platform for multiple limit components 6, the mounting plate 22 needs to have sufficient strength and rigidity to withstand the reaction force during the die-casting process. The opening of the through slot 23 not only reduces the weight of the mounting plate 22 and reduces the moment of inertia, but also provides operating space for the installation and maintenance of the limit components 6. The cross arrangement of the through slot 23 and the limit components 6 allows the operator to access various parts of the limit components 6 from the top or side of the mounting plate 22, which is convenient for adjustment, lubrication or maintenance. At the same time, this layout is also conducive to heat dissipation and avoids heat accumulation during long-term continuous operation. The connection between the mounting plate 22 and the output end of the electric cylinder 21 is fixed with high-strength bolts to ensure the reliability of power transmission and fatigue resistance for long-term use.

[0023] Multiple storage chambers 3 are detachably connected inside the die casting machine body 1. The multiple storage chambers 3 are arranged opposite to multiple through slots 23, and each storage chamber 3 has a discharge port 4 on its bottom wall. A transport component 5 is movably connected inside the die casting machine body 1. It should be noted that the storage bin 3, as a temporary storage unit for the mold heads, realizes centralized management and automatic supply of mold heads. Multiple storage bins 3 correspond to mold heads of different specifications or types. Operators can pre-load the mold heads to be used into the corresponding storage bins 3 according to production needs. The relative arrangement of the storage bins 3 and the through slot 23 ensures that the transport component 5 can accurately push the mold heads from the storage bins 3 to the working area of ​​the die-casting component 2. The discharge port 4 is designed on the bottom wall of the storage bin 3, using gravity to make the mold heads fall automatically onto the working plane of the transport component 5, simplifying the feeding mechanism and reducing failure points. The storage bins 3 and the die-casting machine body 1 are detachably connected, and can be removed as a whole for batch loading of mold heads. The entire storage bin group can also be quickly replaced when changing product types, greatly shortening the line changeover time. The transport component 5, as a mold head conveying device, is responsible for accurately transporting the mold heads from below the storage bins 3 to below each limit component 6. Its movement is coordinated with the action of the die-casting component 2, realizing the automatic mold head replacement process without manual intervention.

[0024] It should be noted that multiple storage bins 3 can be used to store molds of different shapes or sizes. Multiple storage bins 3 are used in conjunction with multiple limiting components 6, and the molds located at the discharge port 4 are transported to the bottom of the die-casting component 2 by the transport component 5, thereby improving the efficiency of the equipment. It should be noted that this design achieves automated management and rapid switching of mold heads, significantly improving the overall efficiency of the equipment. During production, when a certain limiting component 6 needs to replace the mold head, the control system will automatically select the corresponding storage bin 3 according to the current production task and instruct the transport component 5 to move below the discharge port 4 of the storage bin 3. The mold head in the storage bin 3 falls onto the transport component 5 by gravity. Then, the transport component 5 transports the mold head to directly below the target limiting component 6. At this time, the die-casting component 2 drives the limiting component 6 to descend to the mold-changing position, and the drive component 7 opens the limiting plate 66, releasing the old mold head and rising to avoid it. Then, the transport component 5 sends the new mold head into the clamping position, the die-casting component 2 descends again, and the limiting component 6 clamps the new mold head, completing the replacement. The entire process can be fully automated without manual intervention. The existence of multiple storage bins 3 allows the equipment to store multiple specifications of mold heads at the same time, enabling rapid switching when producing different products, realizing flexible production of small batches and multiple varieties, and greatly improving the adaptability and utilization rate of the equipment.

[0025] The transport component 5 includes two synchronous pulleys 51, and a synchronous belt 52 is nested on the outer wall of the two synchronous pulleys 51. A drive motor 54 is detachably connected to the inner cavity of the die casting machine body 1. The output end of the drive motor 54 is fixedly connected to any one of the synchronous pulleys 51. Multiple push bars 53 are fixedly connected to the outer wall of the synchronous belt 52. The mold is pushed to the bottom of the die casting component 2 through the push bars 53. It should be noted that the transport component 5 adopts a synchronous belt drive, which features smooth movement, high positioning accuracy, and simple maintenance. Two synchronous pulleys 51 are respectively installed at both ends inside the die-casting machine body 1, connected by a synchronous belt 52 to form a closed-loop transmission system. The internal teeth of the synchronous belt 52 mesh with the external teeth of the synchronous pulleys 51, eliminating sliding friction and ensuring the synchronicity and accuracy of the transmission. The drive motor 54 adopts a detachable connection method for easy maintenance and replacement. Its output shaft is directly connected to the synchronous pulleys 51, reducing the transmission chain and improving efficiency and reliability. The push bar 53 is fixedly installed on the outer wall of the synchronous belt 52 and moves together with the synchronous belt 52. When the drive motor 54 rotates... When in motion, the synchronous belt 52 drives the pusher 53 to move linearly. The pusher 53 pushes the mold head located at the discharge port 4 along the guide plane until the mold head is accurately pushed directly below the limiting component 6. The spacing of multiple pushers 53 corresponds to the position of the storage bin 3, which can realize the function of simultaneously or sequentially conveying mold heads. The closed-loop motion characteristic of the synchronous belt 52 allows the pusher 53 to be used repeatedly. After completing one push, it continues to move to the next storage bin 3 position for the next push, realizing continuous material supply. The overall structure of the transport component 5 is compact, occupies little space, and is well integrated with the internal space of the die casting machine body 1, without affecting the arrangement and operation of other components.

[0026] Working principle: When the sealing mold needs to be replaced, first rotate the worm gear 72, which drives the worm wheel 71 to rotate. The worm wheel 71 drives the movable housing 62 to rotate, and the movable housing 62 drives the turntable 64 to rotate through the receiving plate 63. Since one end of the limiting plate 66 is fixed, under the drive of the turntable 64 and the connecting rod 65, the limiting plate 66 rotates around the limiting post 610, thereby opening multiple limiting plates 66. Then, the sealing mold to be replaced can be installed in the movable housing 62. After that, rotating the worm gear 72 in the opposite direction will restore the device to its original state. Since multiple limiting plates 66 rotate at the same time, the size between multiple limiting plates 66 can be adjusted, which facilitates the replacement of sealing molds of different sizes. At the same time, since multiple limiting components 6 are set independently, the sealing molds in multiple limiting components 6 can be replaced with sealing molds of different sizes as needed during the use of the equipment, making the device more flexible and capable of producing a variety of sealing components of different sizes or shapes at the same time.
