Description

Technical Field

[0001] This invention relates to the field of metal casting technology, specifically to a high-quality casting mold for machining corrosion-resistant cast iron cylinder liners. Background Technology

[0002] With the continuous advancement of modern industry, the market demand for high-performance engines is increasing, especially for cylinder liners, a crucial component of internal combustion engines. As one of the core components of an engine, the cylinder liner directly affects its overall performance and efficiency. The cylinder liner is typically manufactured using metal casting.

[0003] Chinese patent CN120023303A, authorized and published on May 23, 2025, discloses a cylinder piston casting mold, including a base, an outer mold cavity, an inner mold, and a liquid injection sleeve. The outer mold cavity is slidably connected to both sides of the top of the base, and the inner mold is also connected to both sides of the top of the base. Each outer mold cavity has two mold cavities on its inner sides. When the two outer mold cavities are brought together, the two mold cavities cooperate with the inner mold to form a molding cavity. A liquid injection sleeve is connected to the top of one of the outer mold cavities. Liquid injection channels are provided on the sides of the two outer mold cavities that are close to each other. The two sides of the liquid injection channels communicate with the interiors of the two mold cavities, and the top of the liquid injection channels communicates with the interior of the liquid injection sleeve. In the above application, after the equipment is cast, the finished cylinder liner needs to be manually removed from the mold. However, the rapidly cooled and formed finished cylinder liner is prone to sticking to the mold, which may prevent the demolding process from proceeding smoothly. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-quality casting mold for machining corrosion-resistant cast iron cylinder liners, solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: a high-quality casting mold for machining corrosion-resistant cast iron cylinder liners, comprising:

[0005] A fixed column is provided with a platform on its top. A mold closing device with an automatic mold closing function is provided inside the platform. A mold frame is provided on the inner side of the mold closing device. A casting port is provided on the top of the mold frame. A demolding device is provided at the bottom of the platform.

[0006] A hydraulic block is fixedly connected to the bottom of the platform. A push block is movably connected to the bottom of the hydraulic block. A spring is fixedly connected between the push block and the hydraulic block. One end of a hose is fixedly connected to the bottom of the hydraulic block, and the other end of the hose is fixedly connected to the rear side of the hydraulic block. A groove is formed on the surface of the platform. The rear side of the groove is fixedly connected to the rear side of the hydraulic block. A push block is movably connected to the front side of the hydraulic block. A slider is fixedly connected to the front side of the push block. A demolding spatula is movably connected to the top of the slider. With the demolding spatula, after casting is completed, the mold closing equipment is opened, causing the mold frame to move outward. The demolding equipment moves upward under the drive of the mold frame, causing the movable block to move the finished cylinder liner upward. This increases the internal pressure of the hydraulic block, causing the slider to move inward. The demolding spatula then moves inward with the slider, causing the bottom of the finished cylinder liner to be dislodged by the demolding spatula, separating the finished cylinder liner from the movable block. This makes the demolding process smoother and avoids the finished cylinder liner shrinking due to cold and the movable block getting stuck.

[0007] Preferably, the length of the front end of the demolding spatula is consistent with the wall thickness of the finished cylinder liner.

[0008] Preferably, a mold is fixedly connected inside the mold frame, a movable block is fixedly connected to the top of the demolding device, a release agent spraying assembly is movably connected to the outside of the mold frame, and an anti-jamming assembly is movably connected to the top of the slider.

[0009] Preferably, there are two push blocks, each of which is symmetrically distributed about the center line of the table surface; there are two springs; there are two hydraulic blocks; there are two hoses; there are two hydraulic blocks; there are two slides; there are two push blocks; there are two sliders; and there are two demolding spatulas.

The top of the hydraulic block three is fixedly connected to the bottom of the platform, and the bottom of the hydraulic block three is movably connected to the push block three. A spring two is fixedly connected between the push block three and the hydraulic block three. The top of the hydraulic block three is fixedly connected to one end of the hose two, and the other end of the hose two is fixedly connected to the rear side of the hydraulic block four on the left side. The top of the hydraulic block three is fixedly connected to... One end of the hose three is fixedly connected, and the other end of the hose three is fixedly connected to the rear side of the hydraulic block four on the right. The outer side of the mold frame is fixedly connected to the fixed block two. The rear side of the hydraulic block four is fixedly connected to the outer side of the fixed block two through the fixed block one. The inner side of the hydraulic block four is movably connected to the push block four. The inner side of the push block four is fixedly connected to the rotating block. The two fixed blocks are movably connected to a rotating shaft. The bottom of the rotating shaft is fixedly connected to the top of the rotating block. The outer side of the rotating shaft is fixedly connected to a movable nozzle. The outer side of the movable nozzle is fixedly connected to the feed pipe. A release agent spraying assembly is provided to increase the internal pressure of the hydraulic block three, causing the rotating block to rotate. The rotating shaft follows the rotation of the rotating block, causing the movable nozzle to rotate to the inner side of the mold. The release agent is sprayed from the movable nozzle onto the inner side of the mold, thus ensuring a smooth demolding process and preventing the finished cylinder liner from sticking to the mold.

[0011] Preferably, there are two push blocks three, each push block three is symmetrically distributed about the center line of the table surface, two springs two, two hydraulic blocks three, two hoses two, two hoses three, four fixing blocks one, eight fixing blocks two, each pair of fixing blocks two forms a group, four hydraulic blocks four, four push blocks four, four rotating blocks, four rotating shafts, four movable nozzles, and four feed pipes.

[0012] Preferably, the inner surface of the movable nozzle has multiple spray nozzles.

[0013] Preferably, the anti-jamming assembly includes a fixed block three, a push block five, a hydraulic block five, a hose four, a hydraulic block six, and a push block six. The fixed block three is fixedly connected to the bottom of the platform. The hydraulic block five is fixedly connected to the inner side of the slider. The push block five is movably connected to the inner side of the hydraulic block five. The rear side of the hydraulic block five is fixedly connected to one end of the hose four. The other end of the hose four is fixedly connected to the bottom of the hydraulic block six. The push block six is ​​movably connected to the top of the hydraulic block six. A demolding spatula is fixedly connected to the top of the push block six. By setting up the anti-jamming assembly, when the slider moves inward to its innermost position, the internal pressure of the hydraulic block five increases, causing the push block six to move upward, which in turn causes the demolding spatula to move upward. This causes the finished cylinder liner, which is being pushed by the demolding spatula, to move upward a certain distance, resulting in a more thorough separation of the finished cylinder liner from the moving block and a smoother subsequent material collection process.

[0014] Preferably, there are two fixing blocks three, two push blocks five, two hydraulic blocks five, two hoses four, two hydraulic blocks six, and two push blocks six.

[0015] Preferably, the length of the pusher block six is ​​half the height of the demolding spatula.

[0016] This invention provides a high-quality casting mold for machining corrosion-resistant cast iron cylinder liners. It has the following beneficial effects:

[0017] The corrosion-resistant cast iron cylinder liner is processed with a high-quality casting mold. After the casting is completed, the demolding equipment is started. With the help of push block one, hydraulic block one, hose one, hydraulic block two, and push block two, the slider moves inward along the slide groove, so that the demolding shovel initially loosens the finished cylinder liner from the moving block.

[0018] This corrosion-resistant cast iron cylinder liner is used to process high-quality casting molds. After the demolding equipment is started, it works in conjunction with push block three, hydraulic block three, hose three, hose two, hydraulic block four, push block four, rotating block, and rotating shaft to turn the movable nozzle to the inside of the mold, so that the inside of the mold is evenly sprayed with demolding agent, thus making the next demolding process smoother.

[0019] This corrosion-resistant cast iron cylinder liner is processed into a high-quality casting mold. When the slider moves inward to the innermost side, it works in conjunction with push block five, hydraulic block five, hose four, hydraulic block six, and push block six to make the demolding shovel move upward with push block six, so that the finished cylinder liner is separated from the moving block more thoroughly, and the subsequent material collection process is smoother.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Example 1, please refer to Figures 1-4 A high-quality casting mold for machining corrosion-resistant cast iron cylinder liners, comprising:

[0035] A fixed column 100 is provided, and a platform 200 is provided on the top of the fixed column 100. A mold closing device 300 with an automatic mold closing function is provided inside the platform 200. A mold frame 400 is provided inside the mold closing device 300. The mold frame 400 allows the mold 600 to close more tightly under the action of the mold frame 400. A casting port 500 is provided on the top of the mold frame 400, allowing molten iron to be poured into the mold 600 after it has closed. The bottom of the platform 200... A demolding device 800 is provided, which allows the cooled finished cylinder liner to move upward under the action of the demolding device 800. A mold 600 is fixedly connected inside the mold frame 400. A movable block 700 is fixedly connected to the top of the demolding device 800. The movable block 700 causes the finished cylinder liner to separate from the mold 600. A mold release agent spraying component 1000 is movably connected to the outside of the mold frame 400. An anti-jamming component 1100 is movably connected to the top of the slider 908.

[0036] A hydraulic block 903 is fixedly connected to the bottom of the table 200. A push block 901 is movably connected to the bottom of the hydraulic block 903. A spring 902 is fixedly connected between the push block 901 and the hydraulic block 903. One end of a hose 904 is fixedly connected to the bottom of the hydraulic block 903. The other end of the hose 904 is fixedly connected to the rear side of the hydraulic block 905. The hose 904 is provided so that the interior of the hydraulic block 903 communicates with the interior of the hydraulic block 905. A slide groove 906 is provided on the surface of the table 200. The slide groove 906 is provided so that the slider 908 can move along the slide groove 906. The rear side of the slide groove 906 is fixedly connected to the rear side of the hydraulic block 905. A push block 907 is movably connected to the front side of the hydraulic block 905. A slider 908 is fixedly connected to the front side of the push block 907. A demolding spatula 909 is movably connected to the top of the slider 908.

[0037] The front end length of the demolding spatula 909 is consistent with the wall thickness of the finished cylinder liner;

[0038] There are two push blocks 901, each symmetrically distributed about the center line of the table 200; there are two springs 902; two hydraulic blocks 903; two hoses 904; two hydraulic blocks 905; two slides 906; two push blocks 907; two sliders 908; and two demolding spatulas 909.

[0039] When the casting is completed, the mold closing device 300 is opened, causing the mold frame 400 to move outward. This causes the demolding device 800 to move upward under the action of the mold frame 400, which in turn causes the movable block 700 to move the finished cylinder liner upward. This increases the internal pressure of the hydraulic block 903, causing the slider 908 to move inward. The demolding shovel 909 then moves inward along with the slider 908, causing the bottom of the finished cylinder liner to be scraped by the demolding shovel 909. This separates the finished cylinder liner from the movable block 700, making the demolding process smoother and preventing the finished cylinder liner from shrinking due to cold and jamming the movable block 700.

[0040] During use, after the casting process is completed, the mold closing device 300 is activated, causing the mold frame 400 to move to both sides, separating the mold 600 from the finished cylinder liner. The demolding device 800 moves upward under the influence of the mold frame 400, causing the movable block 700 to move the finished cylinder liner upward. At this time, the push block 901 moves upward, increasing the internal pressure of the hydraulic block 903. This pressure is then transmitted through the hose 904 to the hydraulic block 905, increasing the internal pressure and causing the push block 907 to move inward. The slider 908 moves inward along the slide groove 906 under the influence of the push block 907, causing the demolding spatula 909 to move inward along with the slider 908. The bottom of the finished cylinder liner is scraped by the demolding spatula 909, separating the finished cylinder liner from the movable block 700. This makes the demolding process smoother, preventing the finished cylinder liner from shrinking due to cold and jamming the movable block 700, thus facilitating the subsequent material collection process.

[0041] Example 2, please refer to Figures 1-6Based on Embodiment 1, the release agent spraying assembly 1000 includes a push block 3 1001, a spring 2 1002, a hydraulic block 3 1003, a hose 2 1004, a hose 3 1005, a fixing block 1 1006, a fixing block 2 1007, a hydraulic block 4 1008, a push block 4 1009, a rotating block 1010, a rotating shaft 1011, a movable nozzle 1012, and a feed pipe 1013. The top of the hydraulic block 3 1003 is fixedly connected to the bottom of the table 200. The bottom of 003 is movably connected to push block 3 1001. A spring 2 1002 is fixedly connected between push block 3 1001 and hydraulic block 3 1003. Spring 2 1002 allows push block 3 1001 to automatically reset. The top of hydraulic block 3 1003 is fixedly connected to one end of hose 2 1004. The other end of hose 2 1004 is fixedly connected to the rear side of left hydraulic block 4 1008. Hose 2 1004 is used to connect the interior of hydraulic block 3 1003 with the rear side of left hydraulic block 4 1008. The internal parts of hydraulic block 3 (1003) and hydraulic block 4 (1008) are connected. The top of hydraulic block 3 (1003) is fixedly connected to one end of hose 3 (1005), and the other end of hose 3 (1005) is fixedly connected to the rear side of hydraulic block 4 (1008) on the right. Hose 3 (1005) is installed to ensure communication between the interior of hydraulic block 3 (1003) and the interior of hydraulic block 4 (1008) on the right. The outer side of mold frame 400 is fixedly connected to fixing block 2 (1007), and the rear side of hydraulic block 4 (1008) is fixedly connected to the outer side of fixing block 2 (1007) via fixing block 1 (1006). A push block 1009 is movably connected to the inner side of the hydraulic block 1008. A rotating block 1010 is fixedly connected to the inner side of the push block 1009. A rotating shaft 1011 is movably connected between the fixed blocks 1007. The bottom of the rotating shaft 1011 is fixedly connected to the top of the rotating block 1010. A movable nozzle 1012 is fixedly connected to the outer side of the rotating shaft 1011. The outer side of the movable nozzle 1012 is fixedly connected to the feed pipe 1013. Multiple spray nozzles are opened on the inner surface of the movable nozzle 1012.

[0042] There are two push blocks 3 1001, each push block 3 1001 is symmetrically distributed about the center line of the table 200; there are two springs 2 1002; there are two hydraulic blocks 3 1003; there are two hoses 2 1004; there are two hoses 3 1005; there are four fixing blocks 1 1006; there are eight fixing blocks 2 1007, each pair of fixing blocks 2 1007 forms a group; there are four hydraulic blocks 4 1008; there are four push blocks 4 1009; there are four rotating blocks 1010; there are four rotating shafts 1011; there are four movable nozzles 1012; and there are four feed pipes 1013.

[0043] The mold release agent spraying component 1000 increases the internal pressure of the hydraulic block 1003, causing the rotating block 1010 to rotate. The rotating shaft 1011 rotates with the rotating block 1010, causing the movable nozzle 1012 to rotate to the inside of the mold 600. This allows the mold release agent to be sprayed from the movable nozzle 1012 onto the inside of the mold 600, thus ensuring a smooth demolding process and preventing the finished cylinder liner from sticking to the mold 600.

[0044] In use, based on Example 1, when the demolding device 800 moves upward, the push block 3 1001 moves upward, increasing the internal pressure of the hydraulic block 3 1003. This internal pressure is then transmitted through the hose 2 1004 to the left hydraulic block 4 1008, increasing the internal pressure of the left hydraulic block 4 1008. Excess pressure in the hydraulic block 3 1003 is then transmitted through the hose 3 1005 to the right hydraulic block 4 1008, increasing the internal pressure of the right hydraulic block 4 1008. This causes the push block 4 1009 to be pushed backward, causing the rotating block 1010 to rotate under the action of the push block 4 1009. This causes the rotating shaft 1011 to rotate, thereby rotating the movable nozzle 1012 to the inside of the mold 600. This allows the demolding agent to be sprayed from the movable nozzle 1012 onto the inside of the mold 600, ensuring a smooth demolding process and preventing the finished cylinder liner from sticking to the mold 600.

[0045] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the anti-jamming assembly 1100 includes a fixing block 3 1101, a push block 5 1102, a hydraulic block 5 1103, a hose 4 1104, a hydraulic block 6 1105, and a push block 6 1106. The bottom of the platform 200 is fixedly connected to the fixing block 3 1101. The inner side of the slider 908 is fixedly connected to the hydraulic block 5 1103. The inner side of the hydraulic block 5 1103 is movably connected to the push block 5 1102. The rear side of 3 is fixedly connected to one end of the hose 4 1104, and the other end of the hose 4 1104 is fixedly connected to the bottom of the hydraulic block 6 1105. The hose 4 1104 is set so that the interior of the hydraulic block 5 1103 is connected to the interior of the hydraulic block 6 1105. The top of the hydraulic block 6 1105 is movably connected to the push block 6 1106. The length of the push block 6 1106 is half the height of the demolding shovel 909. The top of the push block 6 1106 is fixedly connected to the demolding shovel 909.

[0046] There are two fixed blocks 3 1101, two push blocks 5 1102, two hydraulic blocks 5 1103, two hoses 4 1104, two hydraulic blocks 6 1105, and two push blocks 6 1106.

[0047] The anti-jamming component 1100 is set up so that when the slider 908 moves inward to the innermost side, the internal pressure of the hydraulic block 1103 increases, causing the push block 1106 to move upward, and the demolding shovel 909 to move upward. This causes the finished cylinder liner being scooped up by the demolding shovel 909 to move upward a certain distance, making the finished cylinder liner more thoroughly separated from the movable block 700, and making the subsequent material collection process smoother.

[0048] In use, based on Embodiment 1 and Embodiment 2, when slider 908 moves inward, push block 5 1102 contacts fixed block 3 1101, push block 5 1102 moves outward, increasing the internal pressure of hydraulic block 5 1103. The internal pressure of hydraulic block 5 1103 is transmitted to hydraulic block 6 1105 through hose 4 1104, increasing the internal pressure of hydraulic block 6 1105. Push block 6 1106 moves upward, causing demolding shovel 909 to move upward. The finished cylinder liner scooped by demolding shovel 909 moves upward a certain distance, making the finished cylinder liner more thoroughly separated from movable block 700, and making the subsequent material collection process smoother.

[0049] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
