Description
Technical Field
The utility model relates to a technical field of insulator pouring for high tension switchgear specifically is an epoxy pours insulator runner structure.
Background
The insulator is a key core part for the GIS high-voltage switch, mainly plays roles of insulation and support in the switch, needs to have high mechanical strength and good electrical insulation performance, and is required to stop the introduction of impurities as much as possible in the pouring process, so that good electrical insulation strength is ensured.
The casting molding of the insulator is that three components of an epoxy resin reinforcing agent and an alumina filler are uniformly mixed and then are cast, cured and molded in a vacuum environment, and each epoxy resin casting insulator manufacturer avoids dust and impurities from being introduced into the insulator in the production process of the insulator by various methods, wherein great progress is made in the aspect of the optimization of the structure of the insulator mold, but the following problems still generally exist: the sprue is difficult to disassemble, the sprue position is easy to cause the blockage of the material pouring of the fastening bolt, and impurities such as dust particles and the like are easy to be introduced to the surface of the cover plate of the mold.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the defect that introduces impurity easily among the above-mentioned pouring process and provide a novel epoxy resin pouring insulator runner structure, specifically speaking is one kind and can realize the pouring of epoxy resin insulator mould, prevents that impurity from introducing the mould, improving drawing of patterns efficiency's device simultaneously, can effectively stop the pouring process impurity and introduce, improves product yield.
The utility model adopts the technical proposal that:
the utility model provides an epoxy pours insulator runner structure, includes the base with mould runner matched with, the inside upper end of this base sets up the stair structure, sets up the rubber seal cover at the stair structure, the rubber seal cover cup joint at the end of funnel landing leg, the feed inlet department of this funnel sets up the helmet.
Furthermore, the base be metal base, this metal base welding adopts the welded mode on the mould apron, fixed convenient and firm, fixed setting can not produce the displacement, precision and security when guaranteeing the pouring.
Furthermore, the rubber sealing sleeve is a silicon rubber sealing sleeve and plays a role in sealing and buffering.
Furthermore, the funnel is a metal funnel, so that the funnel is durable and low in cost.
Furthermore, the metal funnel is a funnel with a horn shape with long supporting legs, so that the feeding is convenient and the fixing is easy.
Furthermore, the protective cap is a silicon rubber protective cap which is soft in texture and convenient to use.
The utility model has the advantages that,
the utility model provides an epoxy resin pouring insulator runner structure increases the mode of long landing leg loudspeaker shape funnel and silicon rubber seal cover cooperation metal welding base through the design on the mould apron, has effectively solved the problem that epoxy pouring insulator easily introduces impurity in the pouring process, improves drawing of patterns efficiency simultaneously.
In a word, utility model's runner structure has effectively prevents that impurity from introducing, and sealing performance is good, and the runner is easily broken off with the fingers and thumb absolutely, and handling efficiency is high, the characteristics that pouring insulator yield is high to have simple, the convenient operation of structural design.
Furthermore, the utility model relates to a principle is reliable, and simple structure has very extensive application prospect.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
The mold comprises a protective cap 1, a rubber sealing sleeve 2, a base 3, a step structure 31, a mold cover plate 4, support legs 5, a feed inlet 6, a mold cavity 7 and a mold sprue 8.
Detailed Description
In order to make the technical solutions in the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
Example 1
As can be seen from figure 1, the utility model discloses an epoxy pours insulator runner structure, include with mould runner 8 matched with metal base 3, this metal base 3 welding adopts the welded mode on mould apron 4, fixed convenient and firm, and fixed setting can not produce the displacement, precision and security when guaranteeing the pouring.
This metal base 3 inside upper end sets up stair structure 31, sets up rubber seal cover 2 on stair structure 31, rubber seal cover 2 be the silicon rubber seal cover, play sealed and cushioning effect, silicon rubber seal cover texture is soft, receives epoxy fracture between gentle external force back metal funnel and the metal base 3, the metal funnel is lifted off, it can to use the ejecting epoxy clout of metal borer stick at last.
The rubber sealing sleeve 2 is sleeved at the tail end of the metal funnel supporting leg 5, and the metal funnel is a horn-shaped funnel with a long supporting leg, so that feeding is facilitated, and fixing is easy. The silicon rubber protective cap 1 is arranged at the feed inlet 6 of the metal funnel, the silicon rubber protective cap 1 is adopted, and the metal funnel is soft in texture and convenient to use.
The working principle is as follows: with reference to fig. 1, further description will be given of the method in which the silicone rubber protective cap 1 is removed before pouring, and the pouring material flows into the mold gate 8 and the mold cavity 7 along the metal funnel and the metal base 3, after being assembled in the manner shown in the drawing, the epoxy resin mixture is poured, which prevents impurities from being easily washed into the mold by the pouring material. And (3) curing the epoxy resin mixture after pouring, demolding after curing, lightly knocking the metal funnel by using a tool in the demolding process, breaking the epoxy resin between the metal funnel and the metal base 3 after the silicon rubber sealing sleeve is soft in texture and is subjected to a slight external force, detaching the metal funnel, and finally ejecting the epoxy resin excess material by using a metal drill rod.
