Abstract
The invention discloses a die for manufacturing a full-closed lightning arrester. The die comprises a die cavity, an upper positioning pin, a lower positioning pin, a limiting block and a positioning block, wherein the upper positioning pin and the lower positioning pin are arranged at the top of the die cavity, the limiting block is arranged at the bottom of the die cavity, and the positioning block is connected with the limiting block. By improving the die, process holes in a core are eliminated, flat appearance of the core is ensured, and the full-closed core is realized by using the flowability of silicon rubber.
Description
Technical field
What the present invention relates to is a kind of mould for the manufacture of arrester, in particular a kind of mould for the manufacture of full-closed lightning arrester.
Background technology
Arrester is a kind of equipment that can absorb overvoltage energy, over-voltage amplitude.When overvoltage occurs, the voltage between arrester two-terminal is no more than setting, makes electrical equipment avoid overvoltage and damages; After overvoltage effect, can make again system recover rapidly normal condition.
At present the manufacture of arrester is by core body is put into die cavity, by the melt silicon rubber in die cavity, is wrapped in core body outer moulding.The appearance out-of-flatness of the arrester that this making mould and preparation method make, not attractive in appearance, sealing is poor simultaneously.
Summary of the invention
Goal of the invention: the object of the invention is to overcome the deficiencies in the prior art, a kind of mould for the manufacture of full-closed lightning arrester is provided, by the improvement to mould, guaranteed the smooth and sealing of arrester outward appearance.
Technical scheme: the present invention is achieved by the following technical solutions, the present invention includes die cavity, upper alignment pin, lower alignment pin, limited block and locating piece; Wherein: upper alignment pin and lower alignment pin are arranged on the top of die cavity, and limited block is arranged on the bottom of die cavity, and locating piece is connected with limited block.
Described die cavity is provided with attemperating unit, for the reaction temperature of observing and controlling die cavity.
The top of described die cavity is provided with cable retainer, for the high temperature cable to core body top, positions.
Beneficial effect: the present invention has the following advantages compared to existing technology: the present invention by the improvement to mould, has not only eliminated the fabrication hole on core body, guarantees outward appearance smooth of core body, utilizes the mobility of silicon rubber to realize core body totally-enclosed simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below embodiments of the invention are elaborated, the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises die cavity 1, upper alignment pin 2, lower alignment pin 3, limited block 4 and locating piece 5; Wherein: upper alignment pin 2 and lower alignment pin 3 are arranged on the top of die cavity 1, and limited block 4 is arranged on the bottom of die cavity 1, and locating piece 5 is connected with limited block 4, and die cavity 1 is provided with attemperating unit 6, for the reaction temperature of observing and controlling die cavity 1.The top of die cavity 1 is provided with cable retainer 7, for the high temperature cable on core body 8 tops is positioned.
The present embodiment is when making arrester, first the top of core body 8 and high temperature cable 9 are welded, then core body 8 is put into die cavity 1, high temperature cable 9 is positioned at the top of die cavity 1 by cable retainer 7, the bottom of core body 8 is fixed on limited block 4, and core body 8 coordinates limited block 4 to be fixed in die cavity 1 by upper alignment pin 2 and lower alignment pin 3.According to the mobility of the interior silicon rubber melt of die cavity 1, first by the coated last layer silicon rubber in the surface of core body 8, then remove alignment pin 2, on silicon rubber is coated by the part of being blocked by upper alignment pin 2 before, in like manner remove again lower alignment pin 3, realization is all coated silicon rubber by the outer surface of core body 8, and forms totally enclosed arrester.
