Abstract
The invention discloses an epoxy casting mold with a height-adjustable upper end cover. The epoxy casting mold comprises a bottom plate (10), an outer mold (20), an inner mold (30), a branching terminal mold (40) and the upper end cover (50), wherein protrusion parts (31) are fixedly mounted on the top surface of the inner mold (30); a through hole is formed in each protrusion part (31); a thread rod (32) is inserted into each through hole; nuts (33 and 34) are connected to each thread rod (32) through threads and are positioned above and below the corresponding protrusion part (31); the lower end of each thread rod (32) is fixedly connected with the upper end cover (50); the upper end cover (50) sleeves the inner mold (30) and can lift along the outer side surface of the inner mold (30). According to the technical scheme, the phenomenon that molds with the corresponding casting heights are prepared due to the difference of the casting heights of epoxy resin is avoided, the production cost is greatly reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to transformer technology field, in particular to the adjustable for height epoxy resin cast mould of a kind of upper end cover.
Background technology
At present, the demand of large capacity Cast Resin Dry-Type Transformer in power equipment market is increasing.The rigid mould of known large capacity Cast Resin Dry-Type Transformer.Along with improving constantly of enterprise's resin casting dry-type transformer technological and manufacturing level and production capacity, oneself is not suitable with the manufacturing of large capacity Cast Resin Dry-Type Transformer high-tension coil traditional rigid casting mold of resin casting dry-type transformer coil, its exist to equipment require high, the manufacture process-cycle is long, expense is high, take up an area the problems such as large, become a large bottleneck that affects each Transformer Manufacturing Enterprises and reduce costs, improve production capacity and benefit.
For solving the problems of the technologies described above, October 7 2009 Granted publication day, the utility model of Granted publication CN201323132Y discloses a kind of large capacity Cast Resin Dry-Type Transformer thin plate mould, this kind of mould by inner mold, outer mold, press-fit frame and bottom plate forms, be characterized in: inner mold and outer mold are thin plate mould, inner mold counterpart place is provided with press strip, and outer mold and outlet panel junction are provided with press strip, and internal mold and outer intermode are equipped with gas tank plate.Although this utility model has advantages of simple in structure, to be lightly suitable for, accessory is alternative good, but, this kind of mould lacks upper end cover, can cause being molded over the epoxy resin end face out-of-flatness on transformer, and, lack the mould of upper end cover in casting process, the epoxy resin being in a liquid state in mould lacks the extruding of upper end cover lower surface, can cause the epoxy resin quality of final molding on transformer not tight.In addition, lack the mould of upper end cover in casting process, be difficult to avoid impurity around to enter in the epoxy resin being in a liquid state, and then the effect of impact cast.Lack the epoxy resin casting mold l day in July, 2009 Granted publication day for another example of upper end cover, the disclosed a kind of pouring mold for stereo wound core resin insulated dry transformer of utility model of Granted publication CN201266543Y.
Summary of the invention
Technical problem solved by the invention: for Cast Resin Dry-Type Transformer casting mold, enterprise reduces transformer manufacturing cost, raising production capacity and benefit to omit the use of upper end cover in mould, causes the epoxy resin being in a liquid state in casting process to make the epoxy resin quality of final molding on transformer not tight because lacking upper end cover lower surface to its extruding.In addition, lack the mould of upper end cover in casting process, be difficult to avoid impurity around to enter in the epoxy resin being in a liquid state, and then the effect of impact cast.And the mould that lacks upper end cover causes being molded over the epoxy resin end face out-of-flatness on transformer.
For solving the problems of the technologies described above, the invention provides following technical scheme: the adjustable for height epoxy resin cast mould of a kind of upper end cover, comprise base plate, be vertically mounted on the external mold on base plate, be vertically mounted on base plate and be positioned at the internal mold of external mold inner side, be vertically mounted on tap terminals mould on base plate, described external mold is provided with axially open, described tap terminals mould is positioned at described opening part, also comprise the upper end cover being arranged on internal mold, on described internal mold end face, be installed with projecting part, described projecting part is the lateral surface of outstanding internal mold radially, the part of the outstanding internal mold lateral surface of described projecting part is offered the through hole of vertical, in described through hole, insert threaded rod, described threaded rod is matched in clearance with coordinating of through hole, two nuts have been threaded on described threaded rod, one of them nut is positioned at the top of projecting part, another one nut is positioned at the below of projecting part, the lower end of described threaded rod is fixedly connected with upper end cover, described upper end cover is sleeved on internal mold and can makes lifting action along the lateral surface of internal mold.
In practical operation, turn is positioned at the nut of projecting part top, nut moves up or down along threaded rod, because the through hole on threaded rod and projecting part is matched in clearance, threaded rod declines or rises along through hole, and the upper end cover that is fixedly connected on threaded rod lower end declines or rises along internal mold lateral surface, when upper end cover declines or rises to precalculated position, turn is positioned at the nut of projecting part below, and the position of retaining thread bar moves up and down to limit it, so fixes the position of upper end cover.By technique scheme, the position of upper end cover can be adjusted arbitrarily, to meet the poured with epoxy resin height of range transformer in actual production, so, possess at Cast Resin Dry-Type Transformer casting mold under the prerequisite of upper end cover, needn't prepare because poured with epoxy resin height is different the mould of corresponding cast height, greatly save production cost, improve production efficiency.By technique scheme, epoxy resin cast mould of the present invention is simple in structure, highly versatile, and the casting quality of epoxy resin can improve in reducing transformer manufacturing cost, improving production capacity and benefit in enterprise.
As technique scheme of the present invention preferably, described projecting part is three that distribute along even circumferential.So design can make upper end cover be raised or decline process in uniform stressed, ensure the normal work of the each parts of internal mold.
As further restriction of the present invention, described projecting part is fixedly mounted on internal mold end face by welding or threaded fastener.Described upper end cover is fixedly connected on the lower end of threaded rod by welding or threaded fastener.
As of the present invention preferred, the sprue gate on described upper end cover is four that distribute along even circumferential.The shape at sprue gate can be circular, can be also the strip-like-shaped of part opening.
As a further improvement on the present invention, described base plate is provided with the protuberance projecting upwards, and described protuberance central position offers circular trough, and the madial wall of described external mold is sleeved on the lateral wall of protuberance, and described internal mold inserts described circular trough.So design can make external mold and internal mold accurately locate, and avoids occurred level displacement in practical operation.As further improvement, the bottom of described circular trough offers several through holes.In casting process, high temperature sharply rises the temperature of internal mold, and the air of interior mold cavity expands, and can cause internal mold to produce upper and lower displacement, particularly the upper surface of internal mold is in the situation of sealing, offers several through holes can discharge air expansion and the heat in inside cavity in the bottom of circular trough.
