Abstract
A kind of epoxy cast dry transformer mould of exempting from end-grain cutting, the cast chamber surrounded by the cast panel of the cast internal mold of inner side, the cast external mold in outside and bottom surface, be built-in with pushing out ring in cast chamber, upper pushing out ring regulates the height between itself and cast panel by stopping means.After this mould utilizes stopping means to make curing molding, pour mass height is consistent with design height, without the need to end-grain cutting.
Description
Technical field
The utility model relates to dry transformer pouring mould tool, specifically a kind of epoxy cast dry transformer mould of exempting from end-grain cutting.
Background technology
Epoxy resin dry type transformer has the features such as corrosion-resistant, moisture resistance, difficult combustion, can run in high humility and other adverse circumstances.This transformer is resin-cast, curing molding, coil is needed to fix in a mold before pouring into a mould it, shaping pour mass insufficient height is not prevented during cast, casting area need higher than design height, after curing molding, use end-grain cutting equipment to be excised by the raised area, ensure that pour mass height is consistent with design height.For avoiding cast height lower than design height, cause damage after moulding by casting, cast highly comparatively design height has very large nargin, and generally exceed 25 ~ 30mm, every platform product three pour mass all will carry out end-grain cutting, and the epoxy resin of average every platform at least 10kg is wasted.
Utility model content
In order to solve the problem, the utility model provides a kind of epoxy cast dry transformer mould of exempting from end-grain cutting, and after utilizing stopping means to make curing molding, pour mass height is consistent with design height, without the need to end-grain cutting.
For realizing above-mentioned utility model object, the technical solution adopted in the utility model is: a kind of epoxy cast dry transformer mould of exempting from end-grain cutting, the cast chamber surrounded by the cast panel of the cast internal mold of inner side, the cast external mold in outside and bottom surface, be built-in with pushing out ring in cast chamber, upper pushing out ring regulates the height between itself and cast panel by stopping means.
Stopping means described in the utility model is made up of connecting plate, fixture and adjusting rod, one end of connecting plate is fixed on mould, and its other end is equipped with adjusting rod, and adjusting rod is connected with upper pushing out ring, adjusting rod can slide up and down along connecting plate, to regulate the height between upper pushing out ring and cast panel.
Adjusting rod described in the utility model is bolt, and connecting plate is provided with the screwed hole matched with adjusting rod.
The utility model beneficial effect is: transform existing use casting mold and process connecting plate, and its one end is fixed can on cast internal mold, and the other end is with threaded hole, and casting mold pushing out ring is uniformly distributed weldering four nuts.After coil winding displacement, dress cast external mold before, connecting plate one end is fixed on cast internal mold on, the other end use bolt make it be connected with upper pushing out ring, by adjusting bolt screw in number, in drive pushing out ring rising or decline.Pushing out ring can be made like this to be adjusted on the height of designing requirement pour mass, fixing cast external mold after regulating, undertaken pouring into a mould, solidifying by technological requirement, cast height is limited because there being upper pushing out ring, namely shaping pour mass height meets design requirement, without the need to carrying out end-grain cutting again, only needing effects on surface to carry out polishing and repairing.Shift manpower and the risk of pour mass when so both removing end-grain cutting from, eliminate again the end-grain cutting time, shorten the production cycle, and avoid the waste of epoxy resin, there is very high economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model;
Be labeled as in figure: 1, pour into a mould internal mold, 2, upper pushing out ring, 3, cast external mold, 4, cast panel, 5, cast charging hole, 6, fixed head, 7, nut, 8, connecting plate, 9, unit bolt nut, 10, adjusting rod, 11, coil, 12, cast chamber.
Embodiment
The specific implementation process of this invention is:
Transform existing casting mold as shown in Figure 1: 1, weld four pieces of 6mm × 50mm × 50mm steel plate at cast internal mold inwall place, position along 100mm place, is uniformly distributed along inwall, steel plate is opened 14 × 20 slotted holes on distance internal mold; 2, on upper pushing out ring, weld four M12 nuts, position with to pour into a mould the fixed head that internal mold welds corresponding.
Four S shape connecting plates are processed: 3, bend the curved connecting plate of a right angle S, one end band elongated hole, the screwed hole of another end band M12 with the wide steel plate of the thick 50mm of 6mm as shown in Fig. 2 item.
Assembling: as shown in Figure 2, before dress cast external mold, first screws in item connecting plate one end with threaded hole by item 12 × 60 bolt, and screws in item M12 nut on upper pushing out ring; Then the other end of item connecting plate is fastening by item M12 unit bolt nut with item fixed head on cast internal mold.At this moment can measure the distance H of upper pushing out ring lower surface bottom casting mold with box chi, this distance is the height of pour mass after moulding by casting, if H is greater than design size, then 12 × 60 bolts are screwed in connecting plate screwed hole, bolt withstands pushing out ring, and pushing out ring is declined, and H reduces; If H is less than design size, then 12 × 60 bolts are screwed out connecting plate screwed hole, upper pushing out ring held by bolt, makes pushing out ring increase, and H increases.
By above-mentioned steps adjustment, until H is consistent with design size, external mold can be loaded onto, pour into a mould by pouring technology, after the demoulding, pour mass height is H, namely consistent with design size.Should be noted and consider resin shrinkage amount, according to our factory's technique, H can be greater than design size 2 ~ 4mm; Need item M12 nut place to smear silicone grease before cast, prevent resin from flowing into and block bolt, impact assembling.
