Description

Technical Field

[0001] This utility model relates to the field of butterfly valve processing technology, specifically to a valve plate forming device for butterfly valve processing. Background Technology

[0002] Butterfly valves are characterized by simple structure, small size, light weight, low material consumption, small installation size, rapid opening and closing, 90° reciprocating rotation, and low driving torque. They are used to cut off, connect, and regulate the flow of media in pipelines, and have good fluid control characteristics and sealing performance.

[0003] Butterfly valve discs are typically manufactured using casting, which usually involves metal molds. If the metal molds malfunction during use, the injection port may become clogged, making it difficult to clean and requiring mold replacement, thus increasing production costs. To address this, we propose a valve disc forming device for butterfly valve manufacturing. Utility Model Content

The upper surface of the sliding plate is provided with sliding seats symmetrically distributed at the four corners. The interior of each sliding seat is provided with sliding holes. The sliding plate is slidably connected between the two sliding rods through the sliding holes.

[0008] Injection molding mechanism: It is located on the right side of the upper surface of the base. The lower right side of the mold assembly is inserted into the interior of the left side of the injection molding mechanism. By modularizing the valve plate forming mold for butterfly valve processing, the production cost is reduced and replacement is facilitated.

[0009] Furthermore, it also includes a microcontroller, which is disposed on the upper surface of the base. The input terminal of the microcontroller is electrically connected to an external power source to control electrical appliances.

[0010] Furthermore, the mold closing mechanism also includes electric push rods. Electric push rods are fixedly connected to the upper surface of the slide plate. The telescopic ends of the electric push rods are fixedly connected to the opposite inner sides of the two fixed plates, and the input ends of the electric push rods are electrically connected to the output end of the microcontroller to realize mold opening and closing.

[0011] Furthermore, the mold assembly includes an upper left mold, a lower left mold, an upper right mold, a lower right mold, and an injection pipe.

[0012] Furthermore, the mold assembly also includes lifting lugs, which are respectively disposed on the front and rear sides of the lower left mold and the lower right mold. The lifting lugs on the same side are connected by bolts, which facilitates the assembly of the lower left mold and the lower right mold.

[0013] Furthermore, the lower ends of the interior of both the lower left and lower right molds are provided with semi-hexagonal pillars, and the relative inner surfaces of the two semi-hexagonal pillars contact each other to form a hexagonal pillar, so that the lower end of the valve plate is provided with a hexagonal hole after it is formed.

The fixed seat is located on the right side of the upper surface of the base, and the second injection pipe is located on the left side of the fixed seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This valve plate forming device for butterfly valve processing has the following advantages:

[0016] When casting valve plates for butterfly valve processing, molten metal is poured into the injection port. The microcontroller controls the external oil pump to start, and the extension end of the hydraulic cylinder pushes the piston to slide to the left inside the second injection pipe, pushing the molten metal into the first injection pipe and then into the entire assembly of the upper left mold, lower left mold, upper right mold, and lower right mold. The lower ends of the lower left and lower right molds are provided with semi-hexagonal prisms. The inner surfaces of the two semi-hexagonal prisms contact to form a hexagonal prism, so that the lower end of the valve plate has a hexagonal hole after forming, which facilitates the centering of the valve plate during subsequent drilling and installation. After the molten metal cools and forms the valve plate, the microcontroller controls the extension ends of the two electric push rods to retract, and the slide plates slide to the adjacent fixed plates. The upper left and upper right molds open, and the valve plate is removed. If a malfunction occurs and the molten metal blocks the first injection pipe, only the corresponding damaged mold needs to be replaced, without replacing the entire mold, saving costs. At the same time, the modular design of the valve plate forming mold makes the valve plate forming process for butterfly valve processing simpler. Attached Figure Description
