Abstract
The utility model relates to a die, which mainly a high-voltage coil of a resin transformer. The upper and the lower end heads of an inner and outer sleeve pipes are mainly and both provided with heat resistance steel rings and are connected to both end plates. The rear end of the heat resistance steel ring is provided with a ring groove of an inner edge and a ring groove of an outer edge. The outer edge of the rear end of a centering plate is provided with the ring groove of the outer edge. An inner heat resistance rubber ring is arranged between the ring groove of the outer edge and the ring groove of the inner edge of the heat resistance steel ring. The outer heat resistance rubber ring is arranged between the ring groove of the outer edge of the heat resistance steel ring and the cylinder wall end of a casing. Thereby, the utility model not only can ensure casing quality, but also can reduce cost.
Description
The utility model relates to a kind of mould, mainly refers to the mould of resin transformer high-voltage coil cast.
At present, being provided with the bulk silicon offset plate in upper and lower two base plates of existing resin transformer high-voltage coil casting mold contacts with the inside and outside sleeve end face, in case when cast liquid resin leak, still, when high temperature is poured into a mould (resin temperature reaches 140 ℃), silica gel plate still can deform, therefore silica gel plate can go out to heave shape on the annulus area of liquid resin cast, and makes resin transformer coil two concave ends, in addition, silica gel plate is a kind of hot-resistant rubber sheet, costs an arm and a leg.
In view of this, the purpose of this utility model provides a kind of resin transformer coil casting mold, upper and lower two base plates are contacted with the resin transformer coil of heat-resisting steel ring with the desire cast, and only at the heat-resisting cushion rubber of the inside and outside crimping of heat-resisting steel ring, still indeformable during with the cast of the upper and lower bottom surface of maintenance mould.
The purpose of this utility model is achieved in that it comprises that mainly a kind of resin transformer coil casting mold comprises inner sleeve, outer sleeve and have the two ends flat board of centering plate, interior, outer sleeve, on, lower end all is provided with heat-resisting steel ring, and be connected on the flat board of two ends, this heat-resisting steel ring rear end offers inner edge annular groove and outer rim annular groove, and also connect the double-screw bolt that stretches out backward in the rear end, offer the outer rim annular groove in centering plate rear end outer rim again, heat-resisting cushion rubber between the inner edge annular groove of this outer rim annular groove and heat-resisting steel ring, being provided with, and heat-resisting cushion rubber outside between the outer rim annular groove of heat-resisting steel ring and outer sleeve wall termination, being provided with.
The double-screw bolt of above-mentioned heat-resisting steel ring is borrowed nut and is held plate level with both hands and be connected.
Owing to adopt such scheme: can guarantee to water the resin transformer coil that outpours correct shape, can reduce cost again.
Below in conjunction with drawings and Examples to the utility model exemplary embodiments.
Fig. 1 the utility model exemplary embodiments schematic diagram.
The A-A cross-sectional schematic of Fig. 2 the utility model exemplary embodiments Fig. 1.
Among the figure: 1, inner sleeve 2, outer sleeve 3, hold plate 31, centering plate level with both hands
311, outer rim annular groove 4, heat-resisting steel ring 41, inner edge annular groove 42, outer rim annular groove
43, double-screw bolt 5, interior heat-resisting cushion rubber 6, outer heat-resisting cushion rubber
Present embodiment mainly comprises inner sleeve 1, outer sleeve 2, two ends flat board 3, two heat-resisting steel ring 4, two interior heat-resisting cushion rubbers 5 and two outer heat-resisting cushion rubbers 6, as shown in Figure 1, and wherein
Inner sleeve 1 and outer sleeve 2 all are to be rolled into two screws with sheet metal to connect into cylinder, belong to prior art.
Two ends flat board 3 is combined steel plates that the inner has circular centering plate 31, is a tight fit on the endoporus termination of inner sleeve 1 with its centering plate 31 front ends.And be connected on the outer sleeve 2 upper and lower end planes with screw, belong to prior art.The rear end outer rim of centering plate 31 offers outer rim annular groove 311.
The rear end of heat-resisting steel ring 4 offers inner edge annular groove 41 and outer rim annular groove 42, and the rear end connects the double-screw bolt 43 that (welding) stretches out backward, be engaged in the upper and lower termination between the inner and outer sleeves 1,2 with its front end annulus, and double-screw bolt 43 is borrowed nut and is held plate 3 level with both hands and be connected.When therefore the resin transformer coil was poured into a mould, the high-temp liquid resin only contacted inner and outer sleeves 1,2 and heat-resisting steel ring 4 between inner and outer sleeves 1,2.
In heat-resisting cushion rubber 5 (silica gel plate) pressure holding between the inner edge annular groove 41 of the outer rim annular groove 311 of centering plate 31 and heat-resisting steel ring 4, the sealing that contacts with heat-resisting steel ring 4 rigidity as inner sleeve 1.
Outer heat-resisting cushion rubber 6 (silica gel plate) pressure holding is between the outer rim annular groove 42 and outer sleeve 2 wall terminations of heat-resisting steel ring 4, as the sealing between its rigidity contact.
