Description

Technical Field

[0001] This utility model belongs to the field of metal casting technology, specifically, it relates to a highly efficient integrated metal casting. Background Technology

[0002] In the field of metal casting production, traditional casting processes typically employ a step-by-step operation, including mold closing, pouring, cooling, mold opening, and ejection. These processes often rely on independent power systems (such as hydraulic, pneumatic, or electric devices) for control, resulting in complex equipment structures, high energy consumption, and time delays between processes, which affect production efficiency.

[0003] Existing casting demolding usually relies on additional hydraulic or mechanical ejection devices, which not only increases equipment costs but may also damage the surface of the casting during the ejection process. The actions of mold closing, mold opening, and ejection are driven by different actuators (such as hydraulic cylinders, motors, etc.), resulting in poor system coordination and high energy consumption.

[0004] To address the aforementioned issues, this application proposes a highly efficient, one-piece metal casting. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a highly efficient integrated metal casting to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A highly efficient, one-piece molded metal casting includes a box body. A lower mold is fixedly installed on the top of the box body. Four symmetrically arranged support rods are slidably connected to the top of the box body. The top of the four support rods is fixedly installed with the same top plate. An upper mold is installed at the bottom of the top plate. The lower mold cooperates with the upper mold. A liquid injection port is installed on one side of the lower mold.

[0008] The ejector mechanism includes two push plates. Two storage slots are opened on the bottom inner wall of the lower mold. The push plates are located in the storage slots. Four symmetrically arranged ejector rods are slidably connected to the bottom of the lower mold. The push plates are fixedly connected to the corresponding two ejector rods. The bottom ends of the four ejector rods are fixedly installed with the same base plate.

[0009] The cooling mechanism includes multiple cooling chambers, which are located inside the lower mold. The lower mold has two symmetrically arranged conversion chambers, and the multiple cooling chambers are located between the two conversion chambers. The lower mold has conduits installed on both sides.

[0010] Preferably, the cooling mechanism further includes a centrifugal pump, which is fixedly installed on the bottom inner wall of the housing. A water outlet pipe is installed on the centrifugal pump, and a liquid guide box is installed on the top inner wall of the housing. One side of the liquid guide box is connected to the water outlet pipe, and the other side of the liquid guide box is connected to a corresponding conduit.

[0011] The centrifugal pump draws coolant from the tank and injects it into the conversion chamber through the liquid guide box and conduit, thereby rapidly cooling the metal casting in the lower mold through the cooling chamber.

[0012] Preferably, the bottom ends of the four support rods are fixedly installed with the same positioning plate, the positioning plate cooperates with the base plate, and a push rod is slidably connected to one side of the liquid guide box. A connecting rod is fixedly installed at one end of the push rod, and two fixing rods are fixedly installed on one side of the connecting rod. Two hinge rods are rotatably connected to the bottom of the fixing rods, and the bottom ends of the hinge rods are rotatably connected to the positioning plate.

[0013] The moving push rod drives the connecting rod to move, the connecting rod pushes the two fixed rods to move, and the fixed rods push the positioning plate to rise and fall through the hinge rod, which in turn drives the support rod and the upper mold to rise and fall, thus facilitating the automatic mold closing and casting of the lower mold and the upper mold.

[0014] Preferably, a movable plate is slidably connected inside the liquid guide box, the movable plate is fixedly connected to the push rod, and a piston plate is slidably connected inside the liquid guide box. Four sliding rods are fixedly installed on one side of the piston plate, and the sliding rods are slidably connected to the movable plate.

[0015] By using a slide rod that is slidably connected to the moving plate and fixedly connected to the piston plate, the movement between the piston plate and the moving plate can be limited.

[0016] Preferably, a top spring is sleeved on the slide rod, the top spring is located between the piston plate and the moving plate, and a stop block is fixedly installed at one end of the slide rod, the stop block and the moving plate cooperate with each other.

[0017] The top spring allows the moving piston plate to act on the moving plate through compression, thereby pushing the push rod to move. The stop block allows the piston plate to retract by pulling the moving plate through the slide rod and the stop block, which in turn drives the push rod to retract.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] Integrated linkage control system

[0020] The mechanical linkage between the piston plate and the top spring is driven by the flow pressure of the coolant, which simultaneously automates the processes of mold closing (upper mold descends), cooling (centrifugal pump injection), and ejection (bottom plate rises). No additional power source is required, achieving efficient conversion between hydraulic energy and mechanical energy.

[0021] Adaptive cooling channel design

[0022] It adopts a nested structure of split cooling chamber and conversion chamber, and forms a closed-loop cooling circuit through the conduit. When the piston plate moves to the bottom of the conduit, the coolant injection is automatically triggered, so as to achieve precise matching of casting forming and cooling sequence.

[0023] The cooling path adopts a Z-shaped layout of "conversion cavity - multiple cooling cavities - reverse conversion cavity" to increase the heat exchange area while ensuring the uniformity of the temperature field.

[0024] Mechanical feedback ejector mechanism

[0025] The positioning plate and top plate are linked. During the mold opening and upward movement, the ejector pin is triggered by contact with the bottom plate. The ejection is completed naturally by utilizing the mold opening and closing stroke, eliminating the need for a separate ejection device.

[0026] The design of the push plate being hidden in the lower mold receiving groove avoids interference from the ejector mechanism with the surface accuracy of the cavity. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] The ejector mechanism 6 includes two push plates 61. Two storage slots are opened on the bottom inner wall of the lower mold 2. The push plates 61 are located in the storage slots. Four symmetrically arranged ejector rods 62 are slidably connected to the bottom of the lower mold 2. The push plates 61 are fixedly connected to the corresponding two ejector rods 62. The bottom ends of the four ejector rods 62 are fixedly installed with the same base plate 63.

[0036] The cooling mechanism 7 includes multiple cooling chambers 71, which are located inside the lower mold 2. The lower mold 2 has two symmetrically arranged conversion chambers 72, and the multiple cooling chambers 71 are located between the two conversion chambers 72. The lower mold 2 is equipped with conduits 74 on both sides.

[0037] Reference Figure 1 and Figure 4 The cooling mechanism 7 also includes a centrifugal pump 73, which is fixedly installed on the bottom inner wall of the housing 1. A water outlet pipe is installed on the centrifugal pump 73. A liquid guide box 8 is installed on the top inner wall of the housing 1. One side of the liquid guide box 8 is connected to the water outlet pipe, and the other side of the liquid guide box 8 is connected to the corresponding conduit 74. The centrifugal pump 73 draws coolant from the housing 1 and injects it into the conversion chamber 72 through the liquid guide box 8 and the conduit 74, thereby rapidly cooling the metal casting in the lower mold 2 through the cooling chamber 71.

[0038] Reference Figure 4 The bottom ends of the four support rods 3 are fixedly installed with the same positioning plate 18. The positioning plate 18 cooperates with the base plate 63. A push rod 10 is slidably connected to one side of the liquid guide box 8. A connecting rod 15 is fixedly installed at one end of the push rod 10. Two fixed rods 16 are fixedly installed on one side of the connecting rod 15. Two hinge rods 19 are rotatably connected to the bottom of the fixed rod 16. The bottom end of the hinge rod 19 is rotatably connected to the positioning plate 18. The moving push rod 10 drives the connecting rod 15 to move. The connecting rod 15 pushes the two fixed rods 16 to move. The fixed rod 16 pushes the positioning plate 18 to rise and fall through the hinge rods 19, which in turn drives the support rods 3 and the upper mold 5 to rise and fall, thereby facilitating the automatic mold closing and casting of the lower mold 2 and the upper mold 5.

[0039] Reference Figure 2A movable plate 11 is slidably connected inside the liquid guide box 8. The movable plate 11 is fixedly connected to the push rod 10. A piston plate 9 is slidably connected inside the liquid guide box 8. Four sliding rods 12 are fixedly installed on one side of the piston plate 9. The sliding rods 12 are slidably connected to the movable plate 11. A top spring 13 is sleeved on the sliding rod 12. The top spring 13 is located between the piston plate 9 and the movable plate 11. A stop block 14 is fixedly installed at one end of the sliding rod 12. The stop block 14 cooperates with the movable plate 11. Through the sliding connection between the sliding rod 12 and the movable plate 11 and the fixed connection between the piston plate 9, the piston plate 9 and the movable plate 11 can be limited. Through the setting of the top spring 13, the moving piston plate 9 can be squeezed by the top spring 13, thereby acting on the movable plate 11 and pushing the push rod 10 to move. The setting of the stop block 14 allows the piston plate 9 to retract. Through the sliding rod 12 and the stop block 14, the movable plate 11 can be pulled to move, thereby driving the push rod 10 to retract.

[0040] Working principle: During operation, centrifugal pump 73 injects water into the outlet pipe, which then enters the liquid guide box 8. This water pushes piston plate 9 from right to left. Piston plate 9, via top spring 13, pushes moving plate 11, which in turn pushes push rod 10. The moving push rod 10 then moves connecting rod 15, which in turn pushes two fixed rods 16. Fixed rods 16, via hinge rod 19, push positioning plate 18 to rise and fall, thereby enabling support rod 3 and upper mold 5 to rise and fall. This facilitates automatic mold closing and casting of lower mold 2 and upper mold 5. When piston plate 9 moves to the position below guide tube 74, top plate 4 pushes upper mold 5 onto lower mold 2, and water flows through... The conduit 74 is introduced into the conversion chamber 72, and the metal casting in the lower mold 2 is rapidly cooled through the cooling chamber 71. Then, it flows back into the box 1 through the conversion chamber 72 on the other side and the conduit 74, thereby rapidly cooling the casting in the lower mold 2. When the centrifugal pump 73 reverses the suction, the liquid guide box 8 drives the piston plate 9 to move in the opposite direction under the action of negative pressure. Then, the sliding rod 12 and the stop block 14 drive the moving plate 11 to retract, thereby driving the positioning plate 18 and the top plate 4 to move upward through the fixing rod 16. When the positioning plate 18 moves to the bottom plate 63, it pushes the bottom plate 63 upward, thereby pushing the metal casting out quickly through the push plate 61, making the entire casting process more efficient and convenient.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
