Casting mould for high-pressure switch transitional coupling bus bar canister

Abstract

The invention discloses a casting mould for a high-pressure switch transitional coupling bus bar canister which comprises upper and lower templates which have a symmetrical structure. Each template comprises a baseboard and a mould arranged on the baseboard. The casting mould is formed by butt jointing the baseboards of the two templates in order to form a spheroid clamped between two cylinders at two ends. The cylinder is provided with a flange structure. A hemispheroid of each template is fixed with a semi-cylinder at one side which is a fixing mould (3). A semi-cylinder at the other side which is moveable is a moveable mould (2). The moveable mould (2) is horizontally rotated on a baseboard (1) by using the spheroid center of the fixing mould (3) as a center and a parting outer spherical surface as a rotating plane. The technical solution of the invention is that the movable mould in the casting mould can perform curvilinear motion relative to the fixing mould and the motion is controllable. Besides, the invention can produce the bending parts which can freely rotate for 0 to 90 degrees and various bending parts can be produced from one set of mould thereby saving the manufacturing cost.

Description

Technical field: [0001] The invention relates to a mold for an elbow connection cylinder, in particular to a casting mold for a transition connection busbar cylinder of a high-voltage switch. Background technique [0002] At present, when the bus barrel in the 252kV gas-insulated metal-enclosed switchgear (GIS) is arranged at the user's site, when it is necessary to turn, the branch bus joint shell transition in the form of a right angle is often used. On the one hand, this connection method cannot be effectively realized. The connection of the shortest distance also puts forward higher requirements on the area of ​​the user's installation site. The use of acute angle transition connection is an effective way to solve this problem. [0003] Because different areas of the same user site may have different requirements for the angle, and different sites of different users may also have different requirements for the angle. Using traditional casting molds, due to the differenc...

Problems solved by technology

[0003] Because different areas of the same user site may have different requirements for the angle, and different sites of different users may also have different requirements for the angle. Using traditional casting molds, due to the difference between the moving mold and the fixed mold in the traditional casting mold The relative movement mode is that the movable mold can move in a straight line or radial direction without hindering the demoulding, and it is impossible to realize the relative curve movement between the movable mold and the fixed mold in the casting mold. Therefore, almost an angle requires a set of molds , the production cost would be too large
