Abstract

The utility model discloses a pouring die of a transformer coil. The pouring die of the transformer coil comprises a base, an inner die body, an outer film, a cover plate and a plurality of axial-direction air duct plates, wherein the inner die body and the outer film are both connected with and arranged on the base, the inner die body is arranged inside the outer film, the cover plate covers an upper end face between the inner die body and the outer film, and therefore a pouring cavity is formed. A plurality of insertion holes are formed in the cover plate, the axial-direction air duct plates are inserted into the corresponding insertion holes in sequence and extend into the pouring cavity, radial-direction air duct plates are further arranged in the pouring cavity, and the radial-direction air duct plates are fixedly connected with the peripheral wall of the inner die body. According to the pouring die of the transformer coil, on the premise that pouring quality is guaranteed, the heat dissipation effect of products can be improved.

Description

The casting mold of transformer coil

Technical field

The utility model relates to a kind of casting mold for the casting transformer coil.

Background technology

Transformer coil can give out very high heat when transformer is worked at present, and these heats are to discharge by the axial air flue of transformer coil mostly, therefore when the cast transformer coil, just must design the axial air flue of transformer coil, traditional transformer coil casting die adopts at the axial direction of transformer and arranges the air flue plate, just form the axial air flue of transformer coil after the demoulding, yet, axially the length of air flue is longer, be not easy to the heat radiation of transformer coil, thereby the excess Temperature that can cause transformer coil can cause transformer to burn out when serious.

Summary of the invention

The purpose of this utility model is to provide under a kind of prerequisite guaranteeing the product casting quality, can improve the casting mold of the transformer coil of product radiating effect.

In order to achieve the above object, the technical solution of the utility model is: a kind of casting mold of transformer coil, comprise the axial air flue plate of base, internal mold, adventitia, cover plate and polylith, internal mold and adventitia all with the base load, internal mold is positioned at adventitia, the cover plate lid is put on the upper surface between internal mold and the adventitia, and formation cast chamber, cover plate is provided with a plurality of jacks, axially the air flue plate inserts in the corresponding jack successively, and stretch into the cast chamber, and also be provided with radially air flue plate in the described cast chamber, radially the air flue plate is fixedly connected with the periphery wall of internal mold.

Described radially air flue plate has two groups that are arranged in parallel, every group radially the air flue plate have four, and all be fixedly connected with the periphery wall of internal mold by screw.

After adopting said structure, because cast also is provided with radially air flue plate in the chamber, radially the air flue plate is fixedly connected with the periphery wall of internal mold or the inwall of adventitia, therefore the periphery of the transformer coil after cast forms radially air flue, therefore not only there is axial air flue to also have radially air flue on the transformer coil, naturally just improved the radiating effect of transformer coil.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Referring to Fig. 1, shown in 2, a kind of casting mold of transformer coil, comprise base 1, internal mold 2, adventitia 3, the axial air flue plate 5 of cover plate 4 and polylith, internal mold 2 and adventitia 3 all with base 1 load, internal mold 2 is positioned at adventitia 3, cover plate 4 lids are put on the upper surface between internal mold 2 and the adventitia 3, and formation cast chamber 6, cover plate 4 is provided with a plurality of jack 4-1, axially air flue plate 5 inserts in the corresponding jack 4-1 successively, and stretches into cast chamber 6, also is provided with radially air flue plate 7 in the described cast chamber 6, radially air flue plate 7 is fixedly connected with the periphery wall of internal mold 2, certainly can also be fixedly connected with the inwall of adventitia 3.

Referring to shown in Figure 1, for actual user demand and the heat radiation requirement that meets transformer coil, more improve the radiating effect of transformer coil, described radially air flue plate 7 has two groups that are arranged in parallel, every group radially air flue plate 7 have four, and all be fixedly connected with by the periphery wall of screw 8 with internal mold 2.

Shown in Fig. 1,2, the utility model is before cast, first internal mold 2 and adventitia 3 are fixed on the base 1, again cover plate 4 lids are put on the upper surface between internal mold 2 and the adventitia 3, and then axial air flue plate 5 inserted in the corresponding jack 4-1 successively, radially air flue plate 7 is fixed on by screw 8 on the periphery wall of internal mold 2 at last, just can carry out pouring practice; Behind casting complete, knockout course is first adventitia 3 and cover plate 4 to be thrown off, again with axial air flue plate 5 and radially air flue plate 7 extractions, radially the existence of air flue plate 7 can not affect the quality of cast and the effect of the demoulding, can also improve the radially heat radiation of transformer coil, the utility model effect in use is apparent.
