Abstract
The utility model discloses a transformer coil casting die capable of overflowing, which comprises an outer die, wherein a flash gate is arranged on the outer die. The utility model has the advantages that redundant casting material overflows automatically from the flash gate after infiltration of casting material, complex manufacturing procedures are not demanded by a solidified coil, and the smooth finish of the surface of the upper end surface of the coil after casting is high. The die has a simple structure, is convenient to use, reduces investment and processing procedures of equipment, lowers the cost, and improves the production efficiency.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of be used for the cast transformer coil can water the casting mold that material feeding is overflowed automatically with unnecessary.
Background technology
The design height of the transformer coil of casting complete is that coil height adds and waters material feeding height.During cast, water material feeding and soak into insulating materials such as glass felt, glass grid and be full of wherein, solidify then.Usually the time be used for control in cast and water the material feeding height, the method that makes coil after the cast meet design height has following two kinds:
One: the height that increases the transformer coil casting mold, even the height of casting mold is higher than the design height of coil, reach design height after material feeding is soaked into when watering, solidify finish after, molded coil is carried out operations such as end face cutting, polishing, reach the design height of coil after treatment.But adopt such casting mold, make the manufacturing of coil have more subsequent handlings such as cutting, polishing, also need to invest specific cutting, grinding apparatus, and the dust that when cutting produces is extremely many, cause environmental pollution easily, influence the health of operator's health.
Its two: casting mold is carried out particular design, increase the positioner of coil design height, location-plate for example, the material feeding of watering that is higher than this location-plate when making cast is separated with the material feeding of watering of satisfying the coil design height, water reach design height after material feeding is soaked into, solidify finish after, take down location-plate, promptly obtain meeting the molded coil of design height.It is special that but mould needs, and the complexity of mould and production cost improve.
The utility model content
The utility model purpose: at the problems referred to above, the purpose of this utility model provides and a kind ofly can make the unnecessary transformer coil casting mold that material feeding is overflowed automatically that waters.
Technical scheme: but a kind of transformer coil casting mold of flash comprises external mold, offers the flash mouth on the described external mold.
The lower edge of described flash mouth to the height of external mold bottom is the design height of coil, after cast, infiltration, overflow, curing are finished, promptly obtains the molded coil highly that adheres to specification.
In band pressure pouring process, do not flow out for the material feeding of watering that makes coil top from the flash mouth, also comprise the seal of the described flash mouth of shutoff.
Best, described seal is an adhesive tape, can plane shutoff flash mouth, do not destroy design height again with interior loop construction.
Beneficial effect: compared with prior art, the utility model has the advantages that watering material feeding soaks into after, the unnecessary material feeding of watering is overflowed automatically from the flash mouth, does not need the coil after solidifying is carried out complicated manufacturing procedure, the coil upper end face surface smoothness height after the cast again.Mould structure is simple, the use aspect, has reduced the investment and the manufacturing procedure of equipment, reduces cost, and enhances productivity.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, but a kind of transformer coil casting mold of flash comprises external mold 1, offers flash mouth 2 on the described external mold 1.
The position of offering of described flash mouth 2 is that the height of the lower edge of this flash mouth 2 to external mold 1 bottom is the design height of coil.
The utility model casting mold is placed coil 4 outsides, block flash mouth 2 as seal 3 at external mold 1 paste outside, then coil 4 is carried out filler cast, pour into the paramount coil design height that goes out with adhesive tape.After material feeding to be poured is soaked into and is full of insulating materials such as glass felt, glass grid, on the curing process time point before gel, manually take down adhesive tape, allow the unnecessary material feeding of watering flow out from flash mouth 2, be cured technology then, remove external mold 1, the coil after can obtaining pouring into a mould carries out some simple deburrings processing to its needs and gets final product.
Claims (4)
