Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plug valve production, in particular to a plug valve production mold facilitating demolding. BACKGROUND

[0002] The plug valve is a valve plate that is always in close contact with the valve seat. Its principle is that a circular opening of the same size as the passageway is opened on the valve plate. By opening and closing the valve plate, the circular opening on the valve plate is completely separated from the passageway and matched, thereby controlling the opening and closing of the flow passage. The plug valve usually includes a valve seat, a valve plate slidingly arranged on the valve seat, and a sealing ring mounted on the valve plate. When the valve is opened and closed, the sealing ring moves synchronously with the valve plate and plays a sealing role.

[0003] For example, the authorized announcement No. "CN218063452U" is named an electric plug valve. The reinforcing ring and the reinforcing rib play the role of increasing the structural strength and impact resistance of the valve plate, so that the valve plate is not easy to crack and damage when it is impacted by the medium transmitted in the valve, which helps to prolong the service life of the valve plate. The reinforcing rib and the reinforcing ring are arranged at the middle and the edge of the valve plate, so that the valve plate is supported at multiple points and has good reinforcing effect, but there are still some problems. The existing electric plug valve needs to use a mold for casting and processing during production. However, because the electric plug valve is basically made of extremely hard metal steel, the plug valve processed in the mold is extremely heavy, and it is difficult to pull it out for demolding by relying on human power. In addition, the plug valve made of metal steel is tightly fitted with the inner wall of the mold, so using a machine to forcibly pry it out may cause deformation or scratching of the plug valve. Therefore, the existing mold for demolding the electric plug valve is not convenient.

[0004] At the same time, the existing electric plug valve needs to use two molds to close together to shape the plug valve material during pressure casting processing in the mold. However, because the upper mold of the pressure casting plug valve is large and heavy, it is impossible for workers to lift it to close the mold. Therefore, a mechanical hoist is used to assist the mold in the closing process. However, the plug valve mold lacks positioning auxiliary structures during the falling process, which may cause the alignment of the upper and lower molds to deviate, resulting in gaps and errors in the closed mold, thereby directly reducing the production quality of the electric plug valve.

[0037] The outer wall of the arc-shaped plate 75 is fixed inside the side plate 2 by the guide wheel 76, which positions the movement of the arc-shaped plate 75. At this time, the hook-shaped head on the inner side of the arc-shaped plate 75 is clamped on both sides of the protrusion 77 to fix the upper mold 6. When the two molds need to be fixed, the power supply is connected to start the two electric push rods 72, which pull the upper inner side of the arc-shaped plate 75 to move inward. At this time, the arc-shaped plate 75 will rotate along the middle pin shaft 74. Because the rotating arc-shaped plate 75 is limited by the guide wheel 76, the ends of the two arc-shaped plates 75 at the lower end will be spread to both sides. At this time, the protrusion 77 loses the fixed point and falls onto the upper side of the lower mold 5 below. Because the positioning plate 71 and the lower end of the lower mold 5 are in the same plane, the upper mold 6 and the lower mold 5 correspond to the mold closing.

The control terminal 4 is electrically connected with the electric push rod 72 through wires. The control terminal 4 is electrically connected with the hydraulic cylinder 81 through wires.

[0039] Working principle:

[0040] First, the guide wheel 76 is fixed inside the side plate 2 to push the outer wall of the arc-shaped plate 75 to position the movement of the arc-shaped plate 75, and the hook-shaped head on the inner side of the arc-shaped plate 75 is arranged to be hooked on both sides of the protrusion 77 to fix the upper mold 6, when the two molds need to be fixed, the power supply is connected to start the two electric push rods 72, the electric push rod 72 pulls the upper inner side of the arc-shaped plate 75 to move inward, at this time, the arc-shaped plate 75 rotates along the middle pin shaft 74, because the arc-shaped plate 75 in rotation is limited by the guide wheel 76, so the two arc-shaped plates 75 at the lower end are opened to both sides, at this time, the protrusion 77 loses the fixed point and falls above the lower mold 5 below, because the positioning plate 71 and the lower end of the lower mold 5 are in the same plane, so the upper mold 6 and the lower mold 5 are correspondingly combined;

[0041] Then the anti-sticking layer 101 adopts a smooth and not easy to stick metal silicone oil coating to facilitate demolding, when the upper mold 5 falls on the lower mold 6, the plugs 82 on both sides are inserted into the butt joint holes 83, the handle 86 is manually moved to drive the turnover sleeve 85 to rotate transversely along the folding page 84, the clamps in the turnover sleeve 85 are inserted into the through holes 81 in the plugs 82 to be fixedly connected and reinforced;

[0042] Then one side of the lower mold 5 can be turned over along the rotating roller 96, when the electric plug valve in the upper mold 6 and the lower mold 5 is processed, the power supply is connected to start the hydraulic cylinder 91, the hydraulic cylinder 91 pushes one end of the lever 92 to press downward, then the other end of the lever 92 is lifted in the opposite direction under the action of the rotating shaft 93, then the lever 92 lifts the supporting rod 94 to push the overturning block 95 upward, the overturning block 95 is made of metal iron and has a slope on one side, which can pass through the base 1 to turn over the lower mold 5 along the rotating roller 96, so that the lower mold 5 falls on the supporting plate 113 above the side, the knocking hammer 124 is made of a relatively impact-resistant metal alloy steel, when the lower mold 5 is turned over, the internal processing electric plug valve assembly is placed upside down on the supporting plate 113, then the power supply is connected to start the motor 122, the motor 122 drives the rotating plate 121 to rotate above the baffle 115, the rotating rotating plate 121 drives the knocking hammer 124 to knock on the lower end of the lower mold 5 through the swing rod 123, and the product stuck in the lower mold 5 is knocked out to be demolded.

[0043] Although the application has been illustrated and described with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
