Description

Technical Field

[0001] This invention relates to the field of water pump casting technology, and in particular to a high-pressure water pump alloy shell forming casting equipment and process. Background Technology

[0002] The high-pressure water pump alloy housing forming and casting equipment is a specialized casting equipment that uses high pressure to inject molten alloy into a metal mold to form the high-pressure water pump alloy housing.

[0003] In the existing technology, the molds used for casting water pump housings do not have an active venting function. This causes the molten metal to be drawn into the casting during the filling process because the gas cannot be discharged in time, forming defects such as porosity and shrinkage. These defects reduce the density of the casting, making the water pump housing prone to leakage problems when operating under high pressure. At the same time, the gas accumulation area also weakens the mechanical properties of the material, resulting in a decrease in local tensile strength and increasing the risk of the housing cracking or breaking.

[0004] Therefore, it is necessary to design a high-pressure water pump alloy shell forming and casting equipment and process to solve the above problems. Summary of the Invention

[0009] As a preferred embodiment of the present invention, the driving assembly includes a fixing frame, which is fixed to the side of the vertical plate. Two guide rods are fixed on the fixing frame, and a sliding frame is slidably sleeved on the two guide rods. A toothed plate is fixed on the sliding frame, and one side of the toothed plate is provided with teeth that are adapted to the toothed ring. A fixing rod is fixed on the top surface of the toothed plate, and the toothed plate is connected to the vertical plate by a tension spring.

[0010] As a preferred embodiment of the present invention, the pushing assembly includes a movable plate and a first cylinder. The first cylinder is mounted on a side plate, and the movable plate is fixed to the telescopic end of the first cylinder. A first rod is slidably disposed on the movable plate. A first magnetic block is fixed to the end of the first rod away from the push rod. A second rod is fixed to the side of the movable plate, and the second rod and the first rod are arranged vertically opposite each other. The second rod is arranged directly opposite the fixed rod.

[0011] As a preferred embodiment of the present invention, the control component includes a guide frame, which is fixed to the side of the side plate. A movable seat is slidably mounted on the guide frame, and a second magnetic block is fixed to the side of the movable seat.

[0012] As a preferred embodiment of the present invention, the shielding assembly includes a second cylinder, which is mounted on a side plate. A baffle is fixed to the telescopic end of the second cylinder. When the guide pipe rotates to a position directly opposite the feeding pipe, the guide pipe is located directly below the baffle.

[0013] As a preferred embodiment of the present invention, the magnetic poles of the second magnetic block and the first magnetic block are opposite poles.

[0014] As a preferred embodiment of the present invention, an electric pusher cylinder is installed on the base plate, the telescopic end of the electric pusher cylinder is fixedly connected to the bottom mold, and two limiting frames are fixed on the base plate. Each limiting frame is slidably provided with a limiting seat, and the two limiting seats are respectively fixed on both sides of the bottom mold.

[0015] A casting process for an alloy housing of a high-pressure water pump includes the following steps: Step 1: Install all components of the casting equipment into place, ensuring the base plate, vertical plates, and other structures are securely connected. Install the bottom mold and top mold on the top plate, fix the top mold to the side plate, connect the feeding pipe to the mold cavity, install the electric push cylinder and connect it to the bottom mold to control the lifting and lowering of the bottom mold, fix the limit frame on the bottom plate and install the upper limit seat, and fix it on both sides of the bottom mold. Check the rotating components, ensuring that the rotating disk is installed on the horizontal plate, the air extraction pipe and the material guide pipe are respectively in the opening, the initial air extraction pipe is directly opposite the feeding pipe, and the gear ring is fitted on the rotating disk. Ensure that other components are normal. Step 2: Start the first cylinder. The telescopic end retracts, causing the moving plate to move. The first rod pushes the push rod, causing the sliding plug to move inside the sealing cylinder. Gas is drawn from the mold cavity through the connecting pipe. When the first magnetic block and the second magnetic block are facing each other, the first magnetic block attracts the second magnetic block under the action of magnetic force, causing the first rod to separate from the push rod, preventing motion interference and ensuring that the gas extraction process proceeds smoothly. Step 3: The first cylinder continues to run, the moving plate drives the second rod to push the fixed rod, causing the toothed plate to move. The teeth mesh with the toothed ring, driving the toothed ring to rotate 180°. The air extraction pipe and the guide pipe are switched. At this time, the first cylinder stops, the guide pipe is directly above the feeding pipe and coaxial, and the guide pipe is located directly below the baffle. The pipe opening is in contact with the baffle to achieve sealing before feeding. Step 4: The staff takes an appropriate amount of molten metal with a container, moves it to one side of the guide tube, controls the second cylinder, and the telescopic end retracts to drive the baffle to move, so that the baffle is separated from the guide tube, creating conditions for pouring molten metal into the mold cavity later, and making the final preparations before feeding. Step 5: After the baffle separates from the feed pipe, the workers quickly pour the molten metal into the feed pipe. The molten metal, aided by gravity, smoothly enters the mold cavity between the bottom mold and the top mold through the feeding pipe, providing the material basis for the forming of the high-pressure water pump alloy shell. Step Six: After all the molten metal has entered the mold cavity, stop the relevant equipment operations and allow the molten metal to cool and solidify naturally in the mold cavity. After a certain period of time, the molten metal will be completely formed, and the high-pressure water pump alloy shell will be obtained, completing the entire casting process.

[0016] The present invention has the following beneficial effects: 1. This invention has an active venting function, which can actively extract the gas in the mold cavity formed by the bottom mold and the top mold before casting, effectively avoiding gas residue in the mold cavity, preventing defects such as bubbles caused by gas when molten metal enters the mold cavity, ensuring the casting quality of the water pump housing, making the shell structure more compact and the performance more stable and reliable after molding, and improving the overall quality of the product. 2. When the first magnetic block moves to the position directly opposite the second magnetic block, the first magnetic block drives the first rod to move under the action of magnetic attraction until it separates from the push rod. This allows the first rod to continue moving even when the slider and the push rod cannot move, thus avoiding motion interference between the push rod and the moving plate and ensuring the smooth operation of the device. 3. Rotatable ball bearings are installed in the groove. When the first rod and the push rod move relative to each other, the ball bearings rotate under the action of friction, which reduces the friction and wear between the first rod and the push rod, and facilitates their smooth separation.

During the lifting and lowering process of the bottom mold 31, the two limit frames and two limit seats provide a limit for the bottom mold 31, ensuring the stability of the bottom mold 31 during movement. A rotating assembly is provided above the top mold 32. The rotating assembly includes a rotating disk 51, which is rotatably mounted on the top surface of the horizontal plate 13. The rotating disk 51 has two openings. One opening has a suction pipe 52 fixed in it, and the other opening has a guide pipe 53 fixed in it. The bottom surface of the rotating disk 51 is in contact with the top surface of the feeding pipe 322. In the initial state, the suction pipe 52 is directly opposite the feeding pipe 322, and the suction pipe 52 and the feeding pipe 322 are coaxially arranged. A toothed ring 511 is fixedly sleeved on the rotating disk 51.

[0021] An air extraction assembly is provided above the top mold 32 to extract gas from the mold cavity. The air extraction assembly includes a sealing cylinder 61, inside which a sliding plug 62 is slidably disposed. A push rod 63 is fixed to the side of the sliding plug 62. The push rod 63 passes through the sealing cylinder 61 and is slidably connected to the sealing cylinder 61. The push rod 63 has an L-shaped structure, and a groove 631 is formed at the end of the push rod 63 away from the sliding plug 62. The sliding plug 62 and the sealing cylinder 61 are connected by a spring 64. The sealing cylinder 61 and the air extraction pipe 52 are connected by a connecting pipe 65. A drive assembly is provided on the side of the vertical plate 11 to drive the rotating disk 51 to rotate. The drive assembly includes a fixing frame 71. The fixing frame 71 is fixed to the side of the vertical plate 11. Two guide rods 72 are fixed on the fixing frame 71. A sliding frame 73 is slidably sleeved on the two guide rods 72. A toothed plate 74 is fixed on the sliding frame 73. One side of the toothed plate 74 is provided with teeth that are adapted to the toothed ring 511. During the movement of the toothed plate 74, the teeth mesh with the toothed ring 511, which can drive the toothed ring 511 to rotate. A fixing rod 741 is fixed on the top surface of the toothed plate 74. The toothed plate 74 and the vertical plate 11 are connected by a tension spring 75. Under the elastic force of the tension spring 75, in the initial state, the toothed plate 74 is in a position close to the vertical plate 11, and the toothed plate 74 and the toothed ring 511 do not contact each other.

[0022] A pushing assembly is provided on the side plate 2 to drive the toothed plate 74 to move. The pushing assembly includes a moving plate 81 and a first cylinder 84. The first cylinder 84 is mounted on the side plate 2. The moving plate 81 is fixed to the telescopic end of the first cylinder 84. A first rod 82 is slidably mounted on the moving plate 81. In the initial state, the end of the first rod 82 is engaged in the groove 631. A first magnet 821 is fixed to the end of the first rod 82 away from the push rod 63. A second rod 83 is fixed to the side of the moving plate 81, and the second rod 83 is vertically aligned with the first rod 82. The second rod 83 is directly opposite the fixed rod 741. A control component is provided to control the position of the first rod 82. The control component includes a guide frame 91, which is fixed to the side of the side plate 2. A movable seat 92 is slidably mounted on the guide frame 91. A second magnetic block 93 is fixed to the side of the movable seat 92. The magnetic poles of the second magnetic block 93 and the first magnetic block 821 are opposite poles. When the first magnetic block 821 moves to a position directly opposite the second magnetic block 93, the first magnetic block 821 will move under the magnetic attraction of the second magnetic block 93 and eventually be attracted to the second magnetic block 93. When the first magnetic block 821 moves, it can drive the first rod 82 to move until the first rod 82 separates from the push rod 63.

[0023] A shielding assembly is provided on the side plate 2. The shielding assembly includes a second cylinder 101, which is mounted on the side plate 2. A baffle 102 is fixed to the telescopic end of the second cylinder 101. When the guide pipe 53 rotates to the position directly opposite the feeding pipe 322, the guide pipe 53 is exactly below the baffle 102. At this time, the opening of the guide pipe 53 is in contact with the bottom surface of the baffle 102. The baffle 102 seals the guide pipe 53 to prevent gas from entering the mold cavity before feeding.

[0024] The implementation principle of this embodiment is as follows: When the water pump housing casting equipment proposed in this invention is in use, in the initial state, the air extraction pipe 52 is directly opposite the feeding pipe 322. Before casting, the first cylinder 84 is running, and its telescopic end retracts. During this process, the telescopic end of the first cylinder 84 drives the moving plate 81 to move. When the moving plate 81 moves, the first rod 82 and the second rod 83 move synchronously. During the movement of the first rod 82, it can push the push rod 63, causing the push rod 63 to drive the sliding plug 62 to move. When the sliding plug 62 moves, it can perform an air extraction action through the connecting pipe 65. During this process, the gas in the mold cavity formed by the bottom mold 31 and the top mold 32 can be drawn into the sealing cylinder. Within 61, the active exhaust function is realized. Furthermore, when the first magnetic block 821 moves to the position directly opposite the second magnetic block 93, the first magnetic block 821 will move under the magnetic attraction of the second magnetic block 93 and eventually be attracted to the second magnetic block 93. When the first magnetic block 821 moves, it can drive the first rod 82 to move until the first rod 82 separates from the push rod 63. When the two separate, the push rod 63 will not block the movement of the first rod 82. Through this design, when the slider 62 and the push rod 63 cannot move, the first rod 82 can still continue to move, avoiding motion interference between the push rod 63 and the moving plate 81, and ensuring the smooth operation of the device.

[0025] While push rod 63 is stationary and first cylinder 84 continues to operate, moving plate 81 continues to move. Subsequently, second rod 83 contacts fixed rod 741 and pushes fixed rod 741 to move. When fixed rod 741 moves, it can drive toothed plate 74 to move. During the movement of toothed plate 74, the teeth mesh with toothed ring 511, which can drive toothed ring 511 to rotate. During the meshing process between toothed plate 74 and toothed ring 511, toothed ring 511 rotates exactly 180°. This causes suction pipe 52 and guide pipe 53 to rotate 180°. At this time, first cylinder 84 stops operating. Under these circumstances, guide pipe 53 moves exactly above feeding pipe 322, and the guide pipe... The guide tube 53 and the feeding tube 322 are coaxially arranged. In addition, when the guide tube 53 is rotated to the position directly opposite the feeding tube 322, the guide tube 53 is exactly below the baffle 102. At this time, the opening of the guide tube 53 is in contact with the bottom surface of the baffle 102. The baffle 102 seals the guide tube 53 to prevent gas from entering the mold cavity before feeding. It should be noted that when the first rod 82 separates from the push rod 63, the first rod 82 continues to move with the moving plate 81. At this time, the first magnetic block 821 can drive the second magnetic block 93 to move. During the movement of the second magnetic block 93, the guide frame 91 and the moving seat 92 provide guidance for the second magnetic block 93.

[0026] After the above operations are completed, the air inside the mold cavity is extracted. Next, the material feeding operation is carried out. During the material feeding, the worker takes out a certain amount of molten metal using a container and moves the container to one side of the guide pipe 53. Then, the second cylinder 101 is controlled to retract its telescopic end. At this time, the baffle 102 will move and separate from the guide pipe 53. After the two separate, the worker immediately pours the molten metal into the guide pipe 53. Subsequently, the molten metal will enter the space between the bottom mold 31 and the top mold 32 through the feeding pipe 322, and finally solidify and form, completing the casting of the water pump housing.

[0027] In summary, the casting equipment proposed in this invention has an active venting function, which can actively expel the gas in the mold cavity before casting, effectively avoiding gas residue in the mold cavity and preventing defects such as bubbles caused by the presence of gas when molten metal enters the mold cavity. This ensures the quality of the water pump housing casting, making the formed water pump housing structure more compact and its performance more stable and reliable, thus improving the overall quality of the product.

[0028] Example 2: Based on Example 1, this example discloses a high-pressure water pump alloy shell forming and casting equipment, such as... Figure 5 As shown, a rotatable ball bearing 632 is provided in the groove 631. When the first rod 82 is placed in the groove 631, the first rod 82 contacts the ball bearing 632. The design of the ball bearing 632 can reduce the friction between the first rod 82 and the push rod 63. When the first magnetic block 821 moves under the action of the second magnetic block 93, the first rod 82 will move relative to the push rod 63. During this process, the ball bearing 632 will rotate under the action of friction. The design of the ball bearing 632 can reduce the wear between the first rod 82 and the push rod 63, which is conducive to the smooth separation between the first rod 82 and the push rod 63.

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.

They control the second cylinder (101) to retract the telescopic end, which drives the baffle (102) to move, so that the baffle (102) is separated from the guide tube (53), creating conditions for pouring molten metal into the mold cavity later and making the final preparations before feeding. Step 5: After the baffle (102) and the guide pipe (53) are separated, the workers quickly pour the molten metal into the guide pipe (53). The molten metal enters the mold cavity between the bottom mold (31) and the top mold (32) smoothly through the feeding pipe (322) by gravity, providing a material basis for the forming of the high-pressure water pump alloy shell. Step Six: After all the molten metal has entered the mold cavity, stop the relevant equipment operations and allow the molten metal to cool and solidify naturally in the mold cavity. After a certain period of time, the molten metal will be completely formed, and the high-pressure water pump alloy shell will be obtained, completing the entire casting process.
