Description

TECHNICAL FIELD

[0001] The application relates to the technical field of iron casting, in particular to a low-temperature impact-resistant nodular iron casting device. BACKGROUND

[0002] ‌Low-temperature impact-resistant nodular iron is a kind of nodular cast iron material with excellent low-temperature impact toughness, which can maintain good mechanical properties in low-temperature environments and meet the needs of specific application scenarios. The development trend of this material lies in its ability to resist low-temperature impact. Through specific production processes and technologies, the use performance of the material in low-temperature conditions is ensured. The production process points of low-temperature impact-resistant nodular iron include the selection of high-purity pig iron as raw material.

[0003] The existing low-temperature impact-resistant nodular iron needs to be cast into the inside of a mold and formed after a period of cooling. In the cooling process, the low-temperature impact-resistant nodular iron gradually forms, but it is easy to condense with the inner wall of the mold during the forming process, which makes it very laborious to take out. Using tools to knock it out is easy to cause damage to the surface of the low-temperature impact-resistant nodular iron, thereby affecting the casting quality of the low-temperature impact-resistant nodular iron. SUMMARY

[0004] The purpose of the present application is to provide a low-temperature impact-resistant nodular iron casting device to solve the problems raised in the background art.

[0005] To solve the above technical problems, the present application is realized by the following technical scheme:

[0006] The present application is a low-temperature impact-resistant nodular iron casting device, which comprises an upper mold, the top of the upper mold is communicated with a feeding pipe, the bottom of the upper mold is provided with a lower mold, the raw materials are poured into the inside of the lower mold through the feeding pipe, and when the inside of the lower mold is filled, it enters the inside of the upper mold. After the inside of the upper mold is filled, the casting is completed, the bottom of the lower mold is fixedly connected with a supporting leg, a groove is formed in the bottom of the inner wall of the lower mold, a discharging part is arranged at the bottom of the lower mold, a protection part is arranged at the bottom of the discharging part, and a vibrating part is arranged on the lower surface of the lower mold.

[0007] The unloading component includes a grooved plate, with a circular hole frame fixedly connected to the end of the grooved plate. The inner wall of the circular hole frame is fixedly connected to the surface of the support leg. A hanging frame is fixedly connected to the end of the grooved plate away from the circular hole frame. After the raw material cools down, the electric push rod is activated to move upward. The electric push rod pushes the upper mold upward through the connecting plate. The hanging frame enters the interior of the upper mold through the feed pipe as the upper mold moves. The electric push rod is fixedly connected to the bottom of the inner wall of the grooved plate to prevent the low-temperature impact balls after molding from condensing on the inner wall of the upper mold. At the same time, the connecting plate pushes the round rod upward through the lifting frame. When the round rod moves, it pushes the adapter plate to separate from the inner wall of the groove. A connecting plate is fixedly connected to the top of the electric push rod. The end of the connecting plate away from the electric push rod is fixedly connected to the top of the upper mold. A lifting frame is fixedly connected to the surface of the connecting plate. A round rod is fixedly connected to the top of the lifting frame. An adapter plate is fixedly connected to the top of the round rod. A spring is fixedly connected to the bottom of the lower mold. The bottom of the spring is fixedly connected to the surface of the lifting frame.

[0008] Furthermore, the end of the grooved plate away from the circular hole frame extends above the upper mold, the lower surface of the vertical frame is adapted to the inner wall of the feed tube, and the end of the connecting plate near the electric push rod is slidably connected to the inner wall of the grooved plate.

[0009] Furthermore, the bottom of the lifting frame extends to the bottom of the lower mold. When the lifting frame moves upward, it drives the bending plate to move through the fixed rod. When the bending plate moves, it pushes the protective frame to move inside the through-hole frame through the rectangular frame. The top of the round rod penetrates the lower mold and extends into the interior of the lower mold. The surface of the adapter plate is adapted to the inner wall of the groove.

[0010] Furthermore, the protective component includes a fixed rod, the top of which is fixedly connected to the bottom of the lifting frame. A curved plate is fixedly connected to the surface of the fixed rod, and a rectangular frame is fixedly connected to the end of the curved plate away from the fixed rod. A protective frame is fixedly connected to the top of the rectangular frame. The protective frame will move to the top of the lower mold. There are four protective frames, which can surround the lower mold to prevent the adapter plate from slipping after pushing out the low-temperature impact ball. A through-hole frame is fixedly connected to the bottom of the lower mold.

[0011] Furthermore, the through-hole frame is interconnected with the lower mold, the surface of the protective frame is adapted to the inner wall of the through-hole frame, the rectangular frame passes through the round hole frame and is slidably connected to the inner wall of the round hole frame, the bottom of the upper mold and the top of the lower mold are in contact with each other, the connecting plate is connected to the upper mold to fix the upper mold and improve the stability when the upper mold and the lower mold are closed, the top of the adapter plate is adapted to the inner wall of the lower mold to avoid unevenness in the low-temperature impact ball during casting, a spring is provided at the bottom of the lower mold, the spring can create resistance to the movement of the lifting frame to prevent the lifting frame from moving too fast, the bottom of the lifting frame extends to the bottom of the round hole plate, the rectangular frame is symmetrically arranged with the protective frame as the center to prevent the protective frame from tilting and getting stuck during lifting, and the bent plate is located on the lower surface of the fixed rod.

[0012] Furthermore, the vibration component includes a fixed block, the end of which is fixedly connected to the lower surface of the lower mold. A recessed plate is fixedly connected to the end of the fixed block away from the lower mold. A contact plate is provided on the surface of the recessed plate. When the electric telescopic rod is activated, it pushes the contact plate to move. When the contact plate moves, it pushes the rubber block to slide on the surface of the recessed plate. Vibration is generated by the friction between the recessed holes on the surface of the recessed plate and the rubber block. The vibration reduces the coagulation force between the low-temperature impact ball and the inner wall of the lower mold. A rubber block is fixedly connected to the surface of the contact plate. An electric telescopic rod is fixedly connected to the bottom of the contact plate. The telescopic end of the electric telescopic rod is slidably connected to the surface of the circular hole frame. A positioning frame is slidably connected to the end of the contact plate. An elastic frame is fixedly connected to the end of the positioning frame.

[0013] Furthermore, the rubber block penetrates the contact plate and is adapted to the inner wall of the concave plate. The end of the contact plate away from the concave plate extends to the bottom of the fixing block. When the rubber block contacts the surface of the concave plate, the contact plate moves. The contact plate is deformed by pulling the elastic frame through the positioning frame, so that the contact plate and the concave plate have toughness to avoid jamming. There are two elastic frames, and the two elastic frames are symmetrically arranged with the positioning frame as the center.

[0014] The present invention has the following beneficial effects:

[0015] The present invention has a discharge component at the bottom of the lower mold. When the discharge component pushes the upper mold to move upward, the discharge component can move upward inside the lower mold to complete the discharge of the low-temperature impact ball. The protective component can move upward synchronously with the upper mold and extend above the lower mold to protect it, preventing the low-temperature impact ball pushed out by the discharge component from slipping. The vibration generated after the vibration component is activated can make the low-temperature impact ball separate from the lower mold quickly, improving the discharge effect of the low-temperature impact ball.

[0016] This invention uses a feed pipe to pour raw materials into the lower mold. Once the lower mold is full, the raw materials enter the upper mold, which is then filled, completing the casting process. After the raw materials have cooled, an electric push rod is activated to move upwards. The electric push rod, via a connecting plate, pushes the upper mold upwards. A hanging bracket, following the movement of the upper mold, enters its interior through the feed pipe, preventing the formed low-temperature impact balls from solidifying on the inner wall of the upper mold. Simultaneously, the connecting plate, via a lifting frame, pushes a round rod upwards. As the rod moves, it separates the adapter plate from the inner wall of the groove and pushes the low-temperature impact balls to the outer end of the lower mold, improving the ease of removing the low-temperature impact balls and preventing them from solidifying inside the lower mold and affecting the casting quality.

[0017] When the lifting frame of this invention moves upward, it drives the bending plate to move through the fixed rod. When the bending plate moves, it pushes the protective frame to move inside the through-hole frame through the rectangular frame. The protective frame will move to the top of the lower mold. There are four protective frames. The four protective frames can surround the mold and prevent the adapter plate from slipping after pushing out the low-temperature impact ball, thus further improving the safety of unloading the low-temperature impact ball.

[0018] This invention activates an electric telescopic rod to move a contact plate. As the contact plate moves, it pushes a rubber block to slide on the surface of a perforated plate. The friction between the perforations on the surface of the perforated plate and the rubber block generates vibration. This vibration reduces the coagulation force between the low-temperature impact ball and the inner wall of the lower mold, and reduces the pressure of the adapter plate on the unloading of the low-temperature impact ball. When the rubber block contacts the surface of the perforated plate, the contact plate moves. The contact plate deforms by pulling the elastic frame through the positioning frame, making the contact plate and the perforated plate resilient and preventing them from getting stuck.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The unloading component 5 includes a grooved plate 10, with a circular hole frame 15 fixedly connected to the end of the grooved plate 10. The inner wall of the circular hole frame 15 is fixedly connected to the surface of the support leg 3. A hanging frame 11 is fixedly connected to the end of the grooved plate 10 away from the circular hole frame 15. An electric push rod 14 is fixedly connected to the bottom of the inner wall of the grooved plate 10. A connecting plate 13 is fixedly connected to the top of the electric push rod 14. The end of the connecting plate 13 away from the electric push rod 14 is fixedly connected to the top of the upper mold 1. A lifting frame 12 is fixedly connected to the surface of the connecting plate 13. A round rod 17 is fixedly connected to the top of the lifting frame 12.

[0032] The end of the grooved plate 10 away from the circular hole frame 15 extends above the upper mold 1. The lower surface of the hanging bracket 11 is adapted to the inner wall of the feed pipe 4. In this invention, raw materials are poured into the interior of the lower mold 2 through the feed pipe 4. After the interior of the lower mold 2 is filled, the raw materials will enter the interior of the upper mold 1. After the interior of the upper mold 1 is filled, the casting is completed. After the raw materials have cooled, the electric push rod 14 is activated to move upward. The electric push rod 14 pushes the upper mold 1 upward through the connecting plate 13. The hanging bracket 11 moves with the upper mold 1 through the feed pipe. 4. Entering its interior, to prevent the low-temperature impact ball after molding from solidifying on the inner wall of the upper mold 1. At the same time, the connecting plate 13 will push the round rod 17 upward through the lifting frame 12. When the round rod 17 moves, it pushes the adapter plate 16 to separate from the inner wall of the groove 8, and pushes the low-temperature impact ball to move to the outer end of the lower mold 2, improving the convenience of the low-temperature impact ball when picking up the material, and preventing the low-temperature impact ball from solidifying inside the lower mold 2 and affecting the casting quality. The end of the connecting plate 13 near the electric push rod 14 is slidably connected to the inner wall of the groove plate 10.

[0033] The bottom of the lifting frame 12 extends to the bottom of the lower mold 2, the top of the round rod 17 passes through the lower mold 2 and extends into the interior of the lower mold 2, and the surface of the adapter plate 16 is adapted to the inner wall of the groove 8.

[0034] The protective component 6 includes a fixed rod 23, the top of which is fixedly connected to the bottom of the lifting frame 12. A curved plate 22 is fixedly connected to the surface of the fixed rod 23. A rectangular frame 21 is fixedly connected to the end of the curved plate 22 away from the fixed rod 23. A protective frame 24 is fixedly connected to the top of the rectangular frame 21. A through-hole frame 20 is fixedly connected to the bottom of the lower mold 2.

[0035] The through-hole frame 20 is connected to the lower mold 2. The surface of the protective frame 24 is adapted to the inner wall of the through-hole frame 20. When the lifting frame 12 moves upward, it drives the bending plate 22 to move through the fixing rod 23. When the bending plate 22 moves, it pushes the protective frame 24 to move inside the through-hole frame 20 through the rectangular frame 21. The protective frame 24 will move to the top of the lower mold 2. There are four protective frames 24. The four protective frames 24 can surround it to prevent the adapter plate 16 from slipping after pushing out the low-temperature impact ball, and further improve the safety of unloading the low-temperature impact ball. The rectangular frame 21 passes through the round hole frame 15 and is slidably connected to the inner wall of the round hole frame 15. The bending plate 22 is located on the lower surface of the fixing rod 23.

[0036] The vibration component 7 includes a fixing block 30. The end of the fixing block 30 is fixedly connected to the lower surface of the lower mold 2. A concave plate 31 is fixedly connected to the end of the fixing block 30 away from the lower mold 2. A contact plate 33 is provided on the surface of the concave plate 31. A rubber block 36 is fixedly connected to the surface of the contact plate 33. An electric telescopic rod 32 is fixedly connected to the bottom of the contact plate 33. The telescopic end of the electric telescopic rod 32 is slidably connected to the surface of the round hole frame 1515. A positioning frame 35 is slidably connected to the end of the contact plate 33. An elastic frame 34 is fixedly connected to the end of the positioning frame 35.

[0037] The rubber block 36 penetrates the contact plate 33 and is adapted to the inner wall of the concave plate 31. The present invention activates the electric telescopic rod 32 to push the contact plate 33 to move. When the contact plate 33 moves, it pushes the rubber block 36 to slide on the surface of the concave plate 31. The concave holes on the surface of the concave plate 31 and the rubber block 36 rub against each other to generate vibration. The vibration reduces the solidification force between the low-temperature impact ball and the inner wall of the lower mold 2, and reduces the pressure of the adapter plate 16 on the unloading of the low-temperature impact ball. When the rubber block 36 contacts the surface of the concave plate 31, it will move the contact plate 33. The contact plate 33 is deformed by pulling the elastic frame 34 through the positioning frame 35, so that the contact plate 33 and the concave plate 31 have toughness to avoid jamming. The end of the contact plate 33 away from the concave plate 31 extends to the bottom of the fixing block 30. There are two elastic frames 34, which are symmetrically arranged with the positioning frame 35 as the center.

[0038] In use, a discharge component 5 is provided at the bottom of the lower mold 2. When the discharge component 5 pushes the upper mold 1 upward, it can move upward inside the lower mold 2, thereby completing the discharge of the low-temperature impact ball. The protective component 6 can move upward synchronously with the upper mold 1 and extend above the lower mold 2 to protect it, preventing the low-temperature impact ball pushed out by the discharge component 5 from slipping. The vibration generated by the vibration component 7 after activation can quickly separate the low-temperature impact ball from the lower mold 2, improving the discharge effect of the low-temperature impact ball. The raw material is poured into the feed pipe 4. The lower mold 2 is filled with raw material, which then flows into the upper mold 1. Once the upper mold 1 is filled, the casting process is complete. After the raw material cools, the electric push rod 14 moves upward. The electric push rod 14, via the connecting plate 13, pushes the upper mold 1 upward. The hanging bracket 11 moves with the upper mold 1 through the feed pipe 4, preventing the low-temperature impact balls from solidifying on the inner wall of the upper mold 1. Simultaneously, the connecting plate 13 pushes the round rod 17 upward via the lifting frame 12. During this movement, the round rod 17 pushes the adapter plate 16 away from the inner wall of the groove 8, and also pushes the low-temperature impact balls... The low-temperature impact ball moves to the outer end of the lower mold 2, improving the ease of unloading the low-temperature impact ball and preventing it from solidifying inside the lower mold 2 and affecting casting quality. When the lifting frame 12 moves upward, it drives the bending plate 22 to move via the fixed rod 23. As the bending plate 22 moves, it pushes the protective frame 24 inside the through-hole frame 20 via the rectangular frame 21. The protective frame 24 moves to the top of the lower mold 2. There are four protective frames 24, which can surround the low-temperature impact ball to prevent it from slipping after the adapter plate 16 pushes it out, further improving the protection of the low-temperature impact ball. For safety during unloading, the electric telescopic rod 32 is activated to push the contact plate 33 to move. When the contact plate 33 moves, it pushes the rubber block 36 to slide on the surface of the concave plate 31. The friction between the concave holes on the surface of the concave plate 31 and the rubber block 36 generates vibration. The vibration reduces the solidification force between the low-temperature impact ball and the inner wall of the lower mold 2, and reduces the pressure of the adapter plate 16 on the unloading of the low-temperature impact ball. When the rubber block 36 contacts the surface of the concave plate 31, it will move the contact plate 33. The contact plate 33 is deformed by pulling the elastic frame 34 through the positioning frame 35, so that the contact plate 33 and the concave plate 31 have toughness to avoid jamming.
