Abstract
The utility model discloses a dry type transformer coil casting mold, which comprises a mold body in which an annular casting chamber is arranged. A flexible gasket and a clamping piece are sequentially arranged at one end of the mold body at least. Supporting rings are also arranged and can block and cover openings arranged at the two ends of the casting chamber of the mold body from the bottom of the flexible gasket when in working. The ring surface of the supporting ring facing toward the internal side is a smooth plane. Since the supporting ring structure is adopted at the two ends of the dry type transformer coil casting mold and one ring surface of the supporting ring is the smooth surface, resin in contact with the smooth plane is flat and is free of concaves, and the de-molded coil only requires small grinding to the burrs and edges and can be input into the assembly process. Thereby, the cutting process of the end part is saved and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of dry-type transformer coil casting mold, belongs to high-tension apparatus manufacturing technology field.
Background technology
At present, the structure of existing dry-type transformer coil casting mold as shown in Figure 1, 2, this mould comprises the die ontology of being made up of internal mold 17 and external mold 16 11, is provided with annular cast cavity 15 between internal mold 17 and the external mold 16; Be provided with the clamping plate 13 that is used for the clamping mold two ends at the two ends of die ontology 11, between clamping area corresponding on clamping plate 13 and the mould, be provided with the rubber slab 12 that is used for sealed mold, clamping plate 13 is strained by screw rod, the rubber slab 12 that clamped plate 13 compresses has played the effect of sealed cast cavity 15, and the casting resin when preventing to pour into a mould in the mould leaks outside.Adopt the casting mold of said structure, there is following problem: because rubber slab has certain flexibility, after compressing, be easy to generate towards domed 14 of cast cavity, make the coil two ends end face after the demoulding have depression, need cut and reconditioning, just can enter assembly process its end, not only waste time and energy, also wasted mould material, dust is bigger in cutting process simultaneously, and operational environment is relatively poor.
The utility model content
The purpose of this utility model provides a kind of dry-type transformer coil casting mold, guarantees that on the basis of mould ends sealing cast back end winding is smooth, to improve the efficient of producing.
In order to realize above purpose, the technical scheme that the utility model adopted is: a kind of dry-type transformer coil casting mold, be provided with the die ontology of annular cast cavity in comprising, at least one end of this die ontology is provided with flexible gasket and clamping element successively, other be provided with when work in the open-ended pushing out ring of cast cavity of flexible gasket bottom surface blanking cover die ontology, the anchor ring of this pushing out ring towards the inboard is smooth flat.
Described pushing out ring and the chamber wall slip inserting of pouring into a mould the open-ended place of cavity.
Described pushing out ring is fixedlyed connected with flexible gasket.
Described pushing out ring and flexible gasket, clamping element are fixedly connected sequentially together.
Another anchor ring of described pushing out ring is provided with blind hole, and this blind hole internal thread is connected with screw rod, and the other end of screw rod is inserted successively and worn described flexible gasket with clamping element and fixedly connected by nut.
Described blind hole is at least two and along the uniform setting of described pushing out ring anchor ring.
Described clamping element is a clamping plate.
Described flexible gasket is a rubber slab.
The structure of pushing out ring has been adopted at the two ends of dry-type transformer coil casting mold of the present utility model, an anchor ring of this pushing out ring is smooth surface, it is smooth to contact this smooth flat resin, there is not depression, coil after the demoulding burr corner angle that only need slightly to polish can enter assembly process, therefore save the operation of end cut, improved the efficient of producing, also improved the environment of work simultaneously.In addition, this pushing out ring is fixedlyed connected by screw rod with clamping plate with rubber slab, compares with existing casting mold, has made things convenient for the location of rubber slab, has improved the installation effectiveness of mould.

Embodiment
Shown in Fig. 3,4,5, dry-type transformer coil casting mold of the present utility model comprises die ontology 1, and this die ontology 1 is made up of external mold 8 and internal mold 9, is provided with the cast cavity 7 of annular between external mold 8 and the internal mold 9; Two ends at die ontology 1 are provided with rubber slab 2 and clamping plate 3 from inside to outside respectively successively, two ends and flexible gasket bottom surface at die ontology 1 are provided with the open-ended pushing out ring 4 of the cast cavity that is used for the blanking cover die ontology, this pushing out ring 4 and the chamber wall slip inserting of pouring into a mould cavity 7 open-ended places, the anchor ring of pushing out ring 4 towards the inboard is smooth flat 6; The clamping plate that is in the die ontology two ends can be strained and fixed by long bolt.Pushing out ring can adopt following structure to fixedly connected with clamping plate with rubber slab: another anchor ring of pushing out ring 4 is provided with some blind holes 22 and along the uniform setting of this anchor ring, is bolted with screw rod 5 in the blind hole 22; The other end of screw rod 5 is inserted successively and is worn rubber slab 2 and clamping plate 3 and cooperate with nut 20, and pushing out ring 4, rubber slab 2 and clamping plate 3 are fixed together.Adopt casting mold of the present utility model when work, casting resin in the die ontology two ends cast cavity contacts with the smooth flat 6 of pushing out ring 4, and the rubber slab of end clamps sealing by clamping plate, make that the two ends end face of the coil after the demoulding is comparatively smooth, the burr corner angle of only need slightly polishing can enter assembly process, therefore save the operation of end cut, improved the efficient of producing.
The two ends of casting mold are fixed and be located to pushing out ring in the foregoing description, rubber slab and clamping plate one, certainly, dry-type transformer coil casting mold of the present utility model can also be only be provided with pushing out ring, rubber slab and clamping plate structure at an end of mould, the other end then adopts sealing means such as welding or one connection, also can realize the purpose of this utility model.In addition, pushing out ring of the present utility model can also be only fixedly connected with rubber slab and the discord clamping plate is connected, clamping plate compresses rubber slab and gets final product in use, pushing out ring and rubber slab can adopt the modes that is connected such as boning or be spirally connected, and so also can reach the location that makes things convenient for rubber slab, the effect that improves the installation effectiveness of mould.
