Description

Technical Field

[0001] This utility model belongs to the field of ball valve casting technology, and more specifically, it relates to a ball valve body precision casting device. Background Technology

[0002] During the production of ball valve body precision castings, tilting pouring machines are automated or semi-automated equipment used to accurately and stably inject molten metal into the mold cavity according to process requirements. Its core function is to control the pouring volume, speed and filling process, and reduce casting defects such as incomplete pouring, cold shuts, and porosity. Existing tilting pouring machines generally consist of a frame, ladle, tilting frame and drive system.

[0003] Existing application number: CN202120503184.9, this utility model discloses a tilting casting machine for casting manufacturing, including a base plate, a fixed pipe fixedly connected to the upper surface of the base plate, a sliding square column slidably connected to the inner wall of the fixed pipe, a support plate fixedly connected to the top of the sliding square column, a support block fixedly connected to the upper surface of the support plate, a through hole opened on the side of the support block, and a rotating shaft rotatably connected to the inner wall of the through hole, a rotating arm fixedly connected to one end of the rotating shaft, and a snap-fit ​​groove opened on the back of the rotating arm, with a casting barrel snapped into place on the inner wall of the snap-fit ​​groove. This tilting casting machine for casting manufacturing, by setting up a fixed pipe, a sliding square column, a lead screw, a large bevel gear, a small bevel gear, and a rotating motor, facilitates the starting of the rotating motor to cause the lead screw to drive the sliding square column to rise and fall, thereby allowing the height of the casting machine to be adjusted according to the mold height and the remaining amount of molten iron in the casting machine, effectively avoiding molten iron splashing during the casting process.

[0004] Based on the above, ball valve bodies vary in size. When the mold opening is small or large, the tilting casting machine can only control the outflow speed of the molten metal by adjusting the tilt angle of the ladle. This may not be able to accurately adapt to the different opening requirements for the outflow speed of the molten metal, resulting in inaccurate flow rate control and causing problems such as molten metal overflow and slow pouring speed. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a precision casting device for ball valve bodies. This device solves the problem that existing ball valve bodies vary in size, and when the mold opening is small or large, the tilting pouring machine relies solely on adjusting the tilt angle of the ladle to control the outflow speed of the molten metal. This may not be able to accurately adapt to the different opening requirements for the outflow speed of the molten metal, resulting in inaccurate flow rate control, causing molten metal overflow, and slow pouring speed.

[0006] The purpose and effect of this utility model's precision casting device for ball valve bodies are achieved through the following specific technical means: A precision casting apparatus for ball valve bodies includes a frame, a tilting frame, a ladle, a discharge port, a drive box, an operating knob, a discharge adjustment component, and a precision control component. The top right end of the tilting frame is hinged to the inside of the frame. The ladle is fixedly connected to the inside of the tilting frame. The discharge port is fixedly connected to the upper right end of the ladle. The drive box is fixedly connected to the upper part of the discharge port. The operating knob is rotatably connected to the left side of the drive box. The discharge adjustment component is disposed inside the drive box. The precision control component is disposed on the right side and inside the discharge port.

[0007] Furthermore, the discharge adjustment assembly includes: a transmission worm, a first transmission shaft, and a transmission worm wheel; the transmission worm is coaxially and fixedly connected to the right end of the operating knob; the first transmission shaft is rotatably connected inside the drive box; the transmission worm wheel is coaxially and fixedly connected to the top of the first transmission shaft, and the transmission worm wheel meshes with the transmission worm.

[0008] Furthermore, the discharge adjustment assembly also includes: a transmission gear and a transmission rack; the transmission gear is coaxially and fixedly connected to the bottom of the first transmission shaft; two transmission racks are provided, and the two transmission racks are slidably connected inside the drive box.

[0009] Furthermore, the discharge adjustment assembly also includes: a connecting sliding rod and a connecting plate; two connecting sliding rods are provided, and the two connecting sliding rods are respectively fixedly connected to the outside of two transmission racks, and the two connecting sliding rods are slidably connected inside the drive box; two connecting plates are provided, and the two connecting plates are respectively fixedly connected to the outer ends of the two connecting sliding rods.

[0010] Furthermore, the discharge adjustment assembly also includes: an adjustment baffle plate; the adjustment baffle plate has an "L" shaped structure, and two adjustment baffle plates are provided.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, by setting up a discharge adjustment component, when the operating knob is turned, the two adjustment baffles move synchronously to the outside or inside, thereby achieving precise control of the discharge port opening size. This effectively adjusts the flow rate of molten metal while keeping the ladle tilt angle constant, solving the problem that it is difficult to accurately control the flow rate by tilt angle alone when the mold opening size is different, and reducing the probability of defects in the ball valve body casting.

[0013] Secondly, by precisely controlling the scale markings and indicator plates in the components, when adjusting the movement of the baffle plate, the corresponding scale markings pointed to by the indicator plate can be used to quickly match the required outlet opening size of different ball valve models. This design allows operators to quickly and accurately complete the adjustment according to the ball valve model, improving adjustment efficiency and speed, and further ensuring the accuracy of the casting process.

[0014] This invention precisely controls the flow rate of molten metal by adjusting the positions of two regulating baffles, and quickly matches the requirements of different ball valve body models by combining scale markings and indicator plates, thereby improving casting accuracy and efficiency. It not only provides reliable support for the high-quality production of ball valve body precision castings, but also promotes the development of ball valve casting technology towards a more precise and efficient direction.

[0023] The discharge adjustment assembly includes: a transmission worm 501, a first transmission shaft 6, and a transmission worm wheel 601; the transmission worm 501 is coaxially and fixedly connected to the right end of the operation knob 5; the first transmission shaft 6 is rotatably connected inside the drive box 4; the transmission worm wheel 601 is coaxially and fixedly connected to the top of the first transmission shaft 6, and the transmission worm wheel 601 meshes with the transmission worm 501.

[0024] The discharge adjustment assembly also includes a transmission gear 602 and a transmission rack 7; the transmission gear 602 is coaxially fixedly connected to the bottom of the first transmission shaft 6; two transmission racks 7 are provided, and the two transmission racks 7 are slidably connected inside the drive box 4.

[0025] The discharge adjustment assembly also includes: a connecting sliding rod 701 and a connecting plate 702; two connecting sliding rods 701 are provided, and the two connecting sliding rods 701 are respectively fixedly connected to the outside of the two transmission racks 7, and the two connecting sliding rods 701 are slidably connected inside the drive box 4; two connecting plates 702 are provided, and the two connecting plates 702 are respectively fixedly connected to the outer ends of the two connecting sliding rods 701.

The outer ends of the two adjustment baffle plates 703 are respectively fixedly connected to the bottom of the two connecting plates 702, and the right ends of the two adjustment baffle plates 703 are separately inserted into the discharge port 301.

[0027] The specific usage and function of this embodiment: When in use, if the opening of the mold to be tilted is small or large, the flow of molten metal cannot be well controlled by the tilt angle of the ladle 3 alone. At this time, the operating knob 5 can be turned, and the transmission gear 602 is driven to rotate through the worm gear transmission mechanism formed by the meshing of the transmission worm 601 and the transmission worm 501. The transmission gear 602 drives the two connecting sliding rods 701 to move outward or inward at the same time through the worm gear transmission mechanism formed by the meshing of the two transmission racks 7. This causes the two connecting plates 702 and the two adjusting baffles 703 to move outward or inward at the same time.

[0030] The specific usage and function of this embodiment are as follows: When the two adjusting baffles 703 move outward or inward simultaneously, the two indicator plates 704 move simultaneously, and multiple scale marks 8 are arranged in an array from the middle position of the discharge port 301 to the rear. The opening size of the two adjusting baffles 703 adapted to the ball valve body of the corresponding model is pre-calibrated. By using the model of the ball valve body, the rear adjusting baffle 703 is moved to the corresponding scale mark 8 pointed to by the driven indicator plate 704, so as to adjust the opening size of the two adjusting baffles 703 more accurately according to the ball valve model, resulting in higher adjustment efficiency and faster speed.
