Cloth.
Preferably, the support unit is set on second end plate.
It is further preferred that the support unit includes being attached at second end plate close to one side surface of inner membrance
First support plate, the first connector for being installed on first support plate on second end plate.
It is further preferred that first support plate with a thickness of 10mm.
It is further preferred that the support unit further includes being attached at second end plate far from inner membrance side table
Second support plate in face, first connector, for first support plate and second support plate to be respectively arranged in
The both side surface of second end plate.
It is further preferred that first connector includes that axially can successively wear to support by described first along it
Plate, the first bolt of second end plate and second support plate, positioned at second support plate side and described first
First nut of bolt thread connection.
It is further preferred that one end of first support plate is attached on second end plate, the other end is along separate
The direction of second end plate central extends outward to form the first extension, and one end of second support plate is attached at described
On two end plates, the other end extends outwardly along the direction far from second end plate central, forms the second extension, and the support is single
Member further includes the second connector for first extension and second extension to link together.
It is further preferred that second connector includes that axially can successively wear to extend by described first along it
Second bolt of portion and second extension, connecting with second bolt thread positioned at second extension side
Second nut.
Due to the application of the above technical scheme, the utility model has the advantage that this is practical new compared with prior art
A kind of transformer coil casting die of type, by the way that support unit is arranged in first end plate or the second end plate, so that coil is perpendicular
Certain insulation distance can be kept when being poured with end by rising, and can make coil casting thoroughly, end is effectively guaranteed
Insulation thickness, avoid security risk, improve the service life of equipment.
