Description
Technical field
The utility model relates to transformer and produces equipment technology field, belongs to especially the casting mold using in a kind of transformer processing and making process.
Background technology
In order to pour into a mould conveniently, existing transformer casting mold, the plug hole on its die cover plate does very greatly, and transformer after casting complete, need to be heating and curing in mould in vacuum tank and drying baker.Because epoxy resin can produce and shrink in solidification process, therefore can make the epoxy resin of originally smooth plug hole and peripheral region thereof produce depression, distortion, become uneven, affect the attractive in appearance of transformer profile, solidify and pulled down after mould, need to transformer bottom polished, be repaired, made it smooth, increase staff's workload, thereby affected production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of novel transformer casting mold, to reach the object of improve production efficiency and product quality.
Transformer casting mold provided by the utility model, comprise die ontology and die cover plate, in die ontology, there is cast chamber, die cover plate is arranged on die ontology top, above die cover plate, be provided with hoisting ring and plug hole, it is characterized in that, described plug hole is provided with the coupling being fixedly connected with, and is connected with funnel by tube connector.
Transformer casting mold provided by the utility model, on plug hole, be connected with funnel, in the time of mould material cure shrinkage, mould material in funnel can add in cast chamber timely, makes the product surface that pours into smooth, has ensured the quality of product, do not need to polish again, repair simultaneously, reduce staff's workload, had and enhance productivity, ensure product quality, and good effect simple in structure, easy to use.
Brief description of the drawings
Accompanying drawing part discloses the utility model specific embodiment, wherein,
Fig. 1, the utility model front view;
Fig. 2, the utility model top view.
Detailed description of the invention
As shown in Figure 1 and Figure 2, transformer casting mold provided by the utility model, comprise die ontology 1 and die cover plate 2, in die ontology, there is cast chamber, die cover plate is arranged on die ontology top, above die cover plate, be provided with four hoisting rings 3 and two plug holes 4, four hoisting rings are separately positioned on four corner positions of die cover plate, two plug holes are arranged on the medium position of die cover plate, described plug hole is provided with the coupling 5 being fixedly connected with, and coupling connects funnel 7 by tube connector 8.For guaranteeing firm and reliable connection, use clip 6 that the junction between coupling and tube connector, tube connector and funnel is fixed.
Taking poured with epoxy resin transformer housing as example, in processing and making process, first funnel is connected in coupling, then the epoxy resin as mould material is injected to cast chamber by one of them funnel, after chamber to be cast fills, more respectively to the appropriate mould material of after-teeming in two funnels.In follow-up vacuumizing and being heating and curing in process, mould material can produce contraction, and now the mould material in funnel will flow downward, and constantly add in the space producing because of contraction, guarantees not leave space in whole cast chamber.After having solidified, first take off funnel, then die ontology and die cover plate are removed, then two pillars that are solidified into by mould material that plug hole place is stayed polish off, whole transformer housing bottom surface is smooth, without caving in, protruding vestige.
Claims (2)
1. a transformer casting mold, comprise die ontology (1) and die cover plate (2), in die ontology, there is cast chamber, die cover plate is arranged on die ontology top, above die cover plate, be provided with hoisting ring (3) and plug hole (4), it is characterized in that, described plug hole is provided with the coupling (5) being fixedly connected with, and is connected with funnel (7) by tube connector (8).
2. transformer casting mold according to claim 1, is further characterized in that, the junction between described coupling and tube connector, tube connector and funnel is fixed by clip (6).
