Description
Technical field
The present invention relates to a kind of insulator heating moulds, and in particular to a kind of insulator chip heating mould.
Background technique,
Insulating part is the weak link in high-tension switch gear, especially epoxy casting insulator in a device application compared with
It is more, so its performance will directly affect the operational reliability of switchgear.It is demonstrated experimentally that in epoxy resin cure forming process
Requirement to temperature is more stringent, directly affects the curing molding quality of insulator.
It is proved according to existing theory and practice, epoxy resin is during curing molding, due to extra-high voltage insulating part
Volume is big, and quality is big, and entire insulator is in upright state when solidification, so gravity must be taken into consideration in actual production
It influences.When insulation, which is walked, successively to be solidified from the bottom up, the insulator of lower part first solidifies, volume contraction, and the insulation on top
Son is also uncured, since the effect of gravity will move downward, forms " glue " effect, in this way, with the progress of reaction, solidification
After molding, the strain of the cured insulator of gradient is relatively small.So being needed in longitudinal direction successively solid from the lower to the upper
Change, while lateral part needs temperature to be controlled in certain range from both sides to internal temperature approach.But existing baking oven technology, only
The temperature gradient of longitudinal direction can be probably kept, temperature controlled precision can not reach requirement, while add certainly if only used
Mold heat controls temperature, and control process is complicated, and stable environment is provided without baking oven, is easy the shadow by external environment
It rings.

The side of piece, the convex mold and negative mold is provided with multiple bolts hole being bolted, the convex mold and negative mold
Top be provided with the sprue gate being connected to the cavity.
As a further improvement of the above technical scheme:
The convex mold includes that inner hole is circular first connecting portion and extends outwardly along the axis hole direction of first connecting portion
And the first flange part for being gradually reduced of its aperture and the first fixed part set on the first flange part end, first electric heating sheets
It is set to the lateral surface of first flange part.
The negative mold include inner hole be circular second connecting portion, extend outwardly along the axis hole direction of second connecting portion and
The second flange part that its aperture is gradually reduced and the second fixed part set on the second flange part end, the second connecting portion and the
One interconnecting piece size is adapted, and the outer shape of second flange part is adapted with the interior shape of the first flange part, so that
Sealing cavity compatible with insulator shape is formed between the second flange part and the first flange part after connection.
The medial surface of second flange part is equipped with four fan-shaped heating zones of equal part, and each heating zone is equipped with and its shape
Compatible first electric heating sheets.
The top edge of the first connecting portion and second connecting portion respectively with respect to be equipped with a protrusion upwardly extended, it is described convex
The inside risen is equipped with groove, so that first connecting portion forms the sprue gate after connecting with second connecting portion；First connection
The lateral surface of portion and second connecting portion is equipped with the second electric heating sheets of multiple strips.
The bottom of the convex mold and negative mold is equipped with bracket.
Hanging ring is equipped in the convex mold and negative mold.
First electric heating sheets are sector.
As shown from the above technical solution, insulator chip heating mould of the present invention, according to the solidification of epoxy resin
Reaction principle and incorporation engineering practice, change it is existing rely solely on baking oven to control the temperature in Curing Process of Epoxy,
By the way that sheet self-heating mold is arranged in template surface, to reach the accurate control to temperature, simultaneously because the presence of baking oven, real
The external environment of epoxy resin in the curing process is relatively stable on border, not will receive the interference of external environment.In this case
The auxiliary by self-heating mold under the insulator produced there is preferable mechanically and electrically quality.
