Summary of the invention
The purpose of this utility model provides a kind of flexible operation, and the mould of adjustable for height resin casting dry-type transformer coil, has saved the mould investment cost, has reduced the cost of product.
For achieving the above object, technical solution scheme of the present utility model is a kind of resin-cast adjustable mold, comprise internal mold, and shell, shell is formed relatively by two semicircular housings, and shell has the sprue gate, and internal mold comprises cylindrical shell, internal mold loam cake and interior baffle plate, internal mold loam cake, interior baffle plate all are packed in the two ends of cylindrical shell, and its innovative point is:
A, internal mold loam cake have the support plate with holes that is connected with it.
Cylindrical shell periphery wall place between b, internal mold loam cake and the interior baffle plate is provided with adjustable loam cake, and there is screw rod to link to each other between adjustable loam cake and the internal mold loam cake, one end of screw rod is fixedly connected on and covers on adjustable, and match with adjustable nut in the hole that the other end passes on the support plate, and the setscrew nut tightening is arranged.
Between described screw rod and the adjustable loam cake is to be threaded, and is fixed by locknut again.The support plate that described internal mold loam cake has is 3~6, and uniform along the cylindrical of internal mold loam cake.The screw flight of described connection internal mold loam cake and adjustable loam cake is M12~M20.
The utility model links to each other with the internal mold loam cake by screw rod because internal mold cylindrical shell periphery wall place has adjustable loam cake, and when turning adjusting nut, screw rod can drive adjustable loam cake and move axially along the cylindrical shell periphery wall, reaches adjusting by the purpose of molded coil height.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing is further described the utility model.
Referring to Fig. 1,2,3, a kind of resin-cast adjustable mold, comprise internal mold 2, with shell 1, shell 1 is formed relatively by two semicircular housings, and shell 1 has sprue gate 1-1, and internal mold 2 comprises cylindrical shell 5, internal mold loam cake 3 and interior baffle plate 4, internal mold loam cake 3, interior baffle plate 4 all are packed in the two ends of cylindrical shell 5, and its innovative point is:
A, internal mold loam cake 3 have the support plate 3-1 with holes that is connected with it;
Cylindrical shell 5 periphery wall places between b, internal mold loam cake 3 and the interior baffle plate 4 are provided with adjustable loam cake 7, and there is screw rod 6 to link to each other between adjustable loam cake 7 and the internal mold loam cake 3, one end of screw rod 6 is fixedly connected on the adjustable loam cake 7, match with adjustable nut 6-3 in the hole that the other end passes on the support plate 3-1, and setscrew nut 6-2 tightening is arranged.
Between described screw rod 6 and the adjustable loam cake 7 is to be threaded, and is fixed by locknut 6-1 again.
The cylindrical shell 5 periphery wall places of described internal mold 2 have designed scalable loam cake 7, scalable loam cake 7 links to each other by screw rod 6 with internal mold loam cake 3, one end of screw rod 6 is threaded with scalable loam cake 7, and there is locknut 6-1 to fix, and passing the hole of support plate 3-1, the other end matches with the adjustable nut 6-3 of support plate 3-1 end face, and setscrew nut 6-2 is positioned at the bottom surface of support plate 3-1, plays positioning action, guarantees that the position of adjustable loam cake can not moved behind the location.
In order to make the adjustable loam cake 7 can be neatly along cylindrical shell 5 axis translations, the support plate 3-1 that described internal mold loam cake 3 has be 3~6, and uniform along the cylindrical of internal mold loam cake 3.Described connection internal mold loam cake 3 is M12~M20 with the screw thread of the screw rod 6 of adjustable loam cake 7.
Convenient in order to lift internal mold, the end face of internal mold loam cake 3 has boatswain chair 3-2, and is same in order to lift the convenience of shell 1, is equipped with lifting bolt 1-2 on two semicircular housings.
Referring to Fig. 1,2,3, resin-cast adjustable mold of the present utility model in use, at first according to the needs of product, unclamp setscrew nut 6-2, turning adjusting nut 6-3 makes on the screw rod 6, following straight line moves, drive adjustable loam cake 7 along cylindrical shell 5 axis translations, when the distance between adjustable loam cake 7 and the interior baffle plate 4 reaches needing of product, 6-2 tightens with setscrew nut, then with screw rod 6 and adjustable loam cake 7 locking positionings, the shell 1 of two halves can be fastened good the cast, though the external diameter of resin-cast adjustable mold internal mold 2 of the present utility model and the internal diameter of shell 1 are fixed, owing to utilize screw rod 6 and adjustable loam cake 7, can be flexible, adjust height easily, so just can make a mold be used in a plurality of in, on the identical and highly different product of overall diameter, saved a large amount of mould investments, reduced the cost of product.
