Description
Technical field
This utility model belongs to metal type dies structure-design technique field, and more particularly to a kind of casting one side has three
The metal type dies of flange disk hole GIS housing.
Background technology
Gas-insulating and fully-enclosed combined electrical apparatus (Gas Insulated Switchgear), English abbreviation GIS.GIS is by breaking
The composition such as road device, disconnecting switch, earthed switch, transformer, spark gap, bus, connector and outlet terminal, these equipment or portion
Part needs all to be enclosed in the housing of metallic ground, and is filled with the SF6 insulating gas of certain pressure in enclosure interior.
For the manufacture of GIS housing, how casting was carried out using resin sand mould in the past, but the casting of resin sand mould
Under the ratio of defects of the housing part made is higher, and production efficiency is relatively low, therefore it is increasingly difficult to be actually needed to meet client,
Metal type dies are gradually adopted to replace traditional resin sand mould for this relevant enterprise, to reduce ratio of defects and to improve production effect
Rate.
For structure relatively simple GIS housing, in two side ends of GIS housing axial direction, in most feelings
The flange disk hole having under condition is one, also has two under a few cases, but either one or two, using routine
The casting that the metal type dies that mode manufactures and designs can meet GIS housing requires.Under special circumstances, client gives one kind
The GIS housing of particular design, specifically as shown in Figures 1 to 3, this GIS housing only has a center flange disk in a side end
Hole, and three flange disk hole are distributed with another side end, and three flange disk hole are evenly distributed, and this have three
The GIS housing of flange disk hole was never predicted before being, when designing metal type dies, problem just occurs in that, if pressed
Design metal type dies according to traditional mode, limited by the special distribution mode of three flange disk hole, the metal of traditional design
Pattern tool will be unable to complete to mold, once die sinking cannot complete, the foundry work of GIS housing also will be unable to continue, and this gives technology
Personnel bring a unprecedented difficult problem.Technical staff has promptly searched related data, but still does not have associated mold design warp
Test and can use for reference, therefore, in order to product is supplied to client it is necessary to the design breaking original metal type dies is thought on time
Road, redesigns the metal type dies that disclosure satisfy that casting requires.
Utility model content
The problem existing for prior art, this utility model provides a kind of casting one side to have three flange disk hole GIS shells

Type mould sections include front template, rear pattern plate, left loose piece and right loose piece, by front template, rear pattern plate, left loose piece and right loose piece split structure
Become three ring flange hole forming mould sections.
, just to setting, front template and rear pattern plate are connected on die main body for described front template and rear pattern plate, front template and after
Template is all molded using horizontal fallback mode.
, just to setting, on described mould, lid lower surface is provided with loose piece guide slide, left work for described left loose piece and right loose piece
Block and right loose piece are all slidably connected by covering on loose piece guide slide and mould, and left loose piece and right loose piece are all using level retrogressing side
Formula molds.
On described mould, lid lower surface is respectively arranged with left boss and right boss, offers left-hand thread on left boss
Hole, is provided with left screw in left-hand thread in the hole, and left screw is paralleled with loose piece guide slide, and left screw one end is movably connected in a left side
On loose piece, the left screw other end extends to and covers outside on mould；Described right boss offers right-hand thread hole, in right-hand thread hole
Right screw is inside installed, right screw is paralleled with loose piece guide slide, right screw one end is movably connected on right loose piece, right screw
The other end extends to and covers outside on mould.
The beneficial effects of the utility model：
This utility model compared with prior art, has broken the mentality of designing of original metal type dies, for GIS housing
The individually designed three ring flange hole forming mould sections in three ring flange hole portion positions, efficiently solving conventional metals pattern tool cannot complete
A difficult problem for die sinking, can smoothly realize the casting that one side has three flange disk hole GIS housings.
