Abstract

The utility model discloses a modular laminated wood does modified line circle casting mold generally does the modified line circle and adopts the laminated wood that multistage 120mm is thick to make for long circle, this combination formula wood system casting mold, including circular arc board (1), sharp board (2), long circular fixing plate (3), fastening screw (4) and 1.1mm polyester film (5), the straight line board is in the centre, and the oval shaped plate of one deck is formed respectively to two circular arc boards in both sides, and every set of mould is formed by stacking the multiply wood axial according to the coil height difference, and fixed plate through screw rod and both ends steps up to form the casting mold of one set of completion with superimposed board, mould coat one deck 1.1mm polyester film as the insulating cylinder of coil with pour into a mould the inside seal layer, the coil is the coiling on 1.1 polyester film. The sharp board combination that wherein the circular arc board can be the same with multiple diameter forms multiple specification mould to has improved mould utility and has rateed, greatly reduced manufacturing cost.

Description

The dry type transformer coil casting mold of modular layer pressed wood

Technical field

This utility model is related to a kind of dry type transformer coil casting mold.

Background technology

The dry casting mold that becomes is the important input in dry-type transformer production, and existing mold is steel die, by steel plate Be processed into the preliminary configuration of coil inwall, in order to after pouring into a mould can smooth withdrawing pattern, needs carry out polish on heavy duty machine tools, raw The product cycle is long, and manufacturing cost is high；Simultaneously every kind of mould can only the same model of coiling coil, utilization rate is low, particularly with non- For mark type transformator, the utilization rate of mould is lower, and steel die considerably increases the production cost of transformator.

The content of the invention

To solve the problems referred to above that prior art is present, this utility model provides the dry type transformer coil cast of modular layer pressed wood Mould, the dry type transformer coil casting mold of modular layer pressed wood can be reused, and arc plate can be with multiple diameter identical straight line Plate is combined；In this scheme, arc section is common board, and the straightway that need to only make various different sizes is in combination, so as to carry High mold use rate；Arc plate and module extender board can stepping production, arc plate diametric(al) and module extender board length direction it is every 10mm is 1 grade, forms multiple combination, so as to the mould service condition of correspondence different size, because mould is segmentation, during withdrawing pattern Sectional to pull out, machining accuracy is reduced, and fully achieves required precision using wood mold coupled, it is not necessary to heavy duty machine tools Polish, greatly reduce die cost.

Its technical scheme taken is：

The dry type transformer coil casting mold of modular layer pressed wood, it is characterised in that：Fix including arc plate, module extender board, Long Circle Plate and fastening screw, arc plate and module extender board it is axially stacking, connect solid by the Long Circle fixed plate at both ends and fastening screw It is fixed, through hole is provided with described Long Circle fixed plate, side is counter sink, is embedded with bolt and nut, it is ensured that the lower surface of mould Smooth, there is sealing good enough the lower surface and lower location-plate for making mould.

Die surface described in the utility model is plane, one strata ester film of surface outer wrap, the outer coiling of mylar There is coil.

The beneficial effects of the utility model are：The mould service condition of this utility model correspondence different size, because mould It is segmentation, sectional during withdrawing pattern to pull out, machining accuracy is reduced, will using the wood mold coupled precision that fully achieves Ask, it is not necessary to the polish of heavy duty machine tools, greatly reduce die cost；

This utility model modular layer pressed wood mould because being made up of multistage, so with very strong interchangeability and versatility.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described further.

As shown in figure 4, the dry type transformer coil casting mold of modular layer pressed wood is made up of core 6, external mold 7, patch panel 8, base plate 9 Whole casting mold；

As shown in figure 1, composition cast core, straight by two sections of 120mm thick-layer pressed woods arc plates 1 and 1 section of 120mm thick-layer pressed wood Line plate 2 constitutes one layer, the entirety and two that each casting mold is made up of arc plate 1, module extender board 2 by multilamellar according to coil height The 40mm thickness Long Circles fixed plate 3 of end is constituted, then is compressed the connection of above-mentioned plate by M10 fastening screws 4, whole so as to constitute Individual cast core；

Before coil winding need on the outside of the core around one layer of 1.1mm mylar 5 both as coil inner sealant layer during cast, Insulating cylinder when assembling as general assembly, coil coiling on mylar.

After cast during withdrawing pattern, will lamination reel mould is sectional extracts, it is time saving and energy saving.

As shown in Fig. 2 the composition of every laminate is illustrated, comprising two sections of 120mm thick circular plates 1 and one section of 120mm thickness straight line Plate 2；Arc plate and module extender board are provided with the through hole of φ 12 as shown in the figure, pass through M10 fastening bolts.Arc plate 1 can be corresponded to The module extender board 2 of the different length of various same diameters being combined, so as to ensure that the interchangeability and versatility of mould, and then be increased Mould utilization rate.

As shown in figure 3, illustrating the structure of 40mm thickness Long Circles fixed plate 3, the screw rod of two φ 12 in fixed plate, is provided with Hole, wherein side are 40 counter sinks of φ, the nut of M10 fastening screws is embedded, it is ensured that the lower surface of mould is smooth, The mould for being has enough sealings with lower location-plate.
