Abstract
The utility model relates to a cast resin transformer coil mold, which can effectively solve the problem that the existing cast transformer is troublesome in operation, has low efficiency and poor use effect. The technical scheme is that the utility model comprises an outer mold and an inner mold, wherein the inner mold is arranged in the outer mold, the inner mold is a cone barrel with a big upper part and a small lower part, the bottom parts of the outer mold and the inner mold are provided with a lower base plate, the upper end and the lower end between the outer mold and the inner mold are provided with an upper position plate and a lower position plate, the upper position plate is provided with a dead head, and the bottom part of the outer mold is provided with a sprue gate. The utility model has simple structure, is convenient to use, and is an innovation of cast transformer coil mold.
Description
One, technical field
The utility model relates to mould, particularly a kind of mould of ast resin transformer coil.
Two, background technology
Traditional cast-type transformer mould, internal mold generally adopts the inner support drum type brake, the processing and fabricating complexity, before coiling, want to put into inner support at the internal mold centre joint earlier, the sealing and the composition surface of fixed mould then, complicated operation, inefficiency, the composition surface is easily dislocation in coiling process and matched moulds process, thereby cause the composition surface to seal bad and the generation seepage, seepage will cause transformer coil to have defective or scrap, and during the demoulding, need first loosening fasteners, the extraction inner support makes in the internal mold and contracts, propose internal mold,, make troubles to operating personnel's work because mould and coil are in hot state during the demoulding, very big potential safety hazard is arranged, so the improvement of cast-type transformer mould and innovation are to need the problem that solves.
Three, utility model content
At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model in time provides a kind of mould of ast resin transformer coil, can effectively solve existing cast-type transformer Mould operation trouble, low and the bad problem of result of use of efficient, the technical scheme of its solution is, comprise external mold and internal mold, internal mold places external mold inside, internal mold is up big and down small conically shaped, and lower shoe is arranged at external mold and internal mold bottom, between external mold and the internal mold on the internal mold upper and lower end parts fixedly is equipped with location-plate and following location-plate, on the last location-plate rising head is arranged, the sprue gate is arranged at the external mold bottom, and the utility model is simple in structure, easy to use, be the innovation on the transformer coil casting mold.
Four, description of drawings
Accompanying drawing is a sectional front view of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provide by accompanying drawing, the utility model comprises external mold and internal mold, internal mold 2 places external mold 1 inside, internal mold 2 is up big and down small conically shaped, lower shoe 3 is arranged at external mold 1 and internal mold 2 bottoms, in internal mold 2 upper and lower end parts location-plate 4 and following location-plate 5 are housed fixedly between external mold 1 and the internal mold 2, on the last location-plate 4 rising head 6 are arranged, sprue gate 10 is arranged at external mold 1 bottom.
In order to guarantee result of use and raise the efficiency that the suspension hook 7 of symmetry is arranged at said internal mold 2 tops.
Said internal mold 2 inner upper and lower sides have pushing out ring 8, improve the intensity of internal mold 2.
Said external mold 1 is upper and lower isodiametric hollow cylinder.
Operating position of the present utility model is, earlier with transformer coil 9 around the home on internal mold 2 outer walls, then at internal mold 2 outside suit external molds 1, load onto lower shoe 3, after fastening, transformer coil 9 casting resins through sprue gate 10 between external mold 1 and internal mold 2 are during the demoulding, take away external mold 1, because internal mold 2 is the integral conical bucket, the demoulding is easy, and having saved in the past, internal mold needs the operation of assembling repeatedly, improved operating efficiency greatly, solved resin and revealed the problem that causes transformer coil to be scrapped.
The utility model is simple in structure, easy to use, has solved traditional cast-type transformer mould use trouble, the problem that efficient is low and result of use is bad, is the innovation on the transformer teeming mould.
