Description
Technical field
The present invention relates to a kind of mould, specifically, relate to a kind of composite sheath explosion-proof and prevent into gum forming mould, belong to voltage levels polymeric metal oxide surge arrester technical field.
Background technology
The core body that voltage levels polymeric metal oxide surge arrester is mainly become with resistor disc combo by composite sheath and other related components form.The injection moulding of composite sheath is an important procedure in arrester manufacturing process.
Conventional composite sheath mould adopts fixed, and namely die cavity two ends adopt card slot type structure, is placed in fixing mould draw-in groove after insulating cylinder collocation lining, matched moulds also injects silicon rubber, silicon rubber is flowed into by hole for injecting glue, injects umbrella cover cavity space, through high temperature vulcanized shaping by runner.Because insulating cylinder under the high temperature conditions certain expansion can occur, when the length of insulating cylinder coordinates improper with die size, insulating cylinder after expansion can withstand in the draw-in groove at die cavity two ends, be easy to cause insulating cylinder to burst, therefore can consider the expansion space of 2 ‰ ~ 4 ‰ when designs of mold cavities length, explosion problem can obtain sizable improvement.Although considered the thermal expansion percentage elongation of insulating cylinder, but still end Decrepitation Phenomena can occur.In addition, owing to having reserved expansion space, because insulating cylinder does not also expand during injection, sizing material can enter in the space of insulating cylinder, lining, die cavity end three formation along gap under huge injection pressure, the sizing material entered is owing to can not contact completely with mould, and temperature can not reach cures requirements, and insulating cylinder and lining can bond together by it, shaping complete after, lining is difficult to take out in insulating cylinder.Meanwhile, enter into insulating cylinder silk tooth, the silicon rubber of sleeve surface is difficult to clear up, have a strong impact on the qualification rate of production efficiency and product.
For this reason, a kind of new technical scheme is needed to solve the problems referred to above.
Summary of the invention
A kind of composite sheath explosion-proof is the object of the present invention is to provide to prevent into gum forming mould.
The technical solution used in the present invention is:
A kind of composite sheath explosion-proof is prevented into gum forming mould, comprise framed, die cavity, runner, hole for injecting glue, insulating cylinder and lining, described die cavity, runner is connected with hole for injecting glue three, described lining is placed in also coordinated insulation cylinder use in insulating cylinder, it also comprises protective sleeve, retractor device, left push rod and right push rod, described protective sleeve is arranged on the left end of lining, described retractor device is arranged on the right-hand member of lining, described insulating cylinder is arranged between protective sleeve and retractor device, described left push rod be arranged on die cavity left end framed on, described right push rod be arranged on die cavity right-hand member framed on.
Further, the left end of described die cavity is provided with excessive glue groove, and described excessive glue groove is connected with die cavity.
Further, the center line of described left push rod, right push rod and die cavity three is located along the same line.
Advantage of the present invention: structure is simple, easy to operate, not only can efficiently avoid the generation of insulating cylinder end Decrepitation Phenomena, improve the qualification rate of product, but also can effectively avoid sizing material to enter in insulating cylinder, can carry out the optimum quantum of utilization of meticulous silicon rubber according to the excessive glue amount in excessive glue groove, thus materials are produced in raising product percent of pass and saving simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of composite sheath explosion-proof is prevented into gum forming mould, comprises framed 1, die cavity 2, runner 3, hole for injecting glue 4, insulating cylinder 5, lining 6, protective sleeve 7, retractor device 8, left push rod 9 and right push rod 10.Die cavity 2, runner 3 are connected with hole for injecting glue 4 three; lining 6 is placed in the interior also coordinated insulation cylinder 5 of insulating cylinder 5 and uses; protective sleeve 7 is arranged on the left end of lining 6; retractor device 8 is arranged on the right-hand member of lining 6; insulating cylinder 5 is arranged between protective sleeve 7 and retractor device 8; left push rod 9 is arranged on framed 1 of die cavity 2 left end; right push rod 10 is arranged on framed 1 of die cavity 2 right-hand member; the center line of left push rod 9, right push rod 10 and die cavity 2 three is located along the same line; the left end of die cavity 2 is provided with excessive glue groove 11, and the glue groove 11 that overflows is connected with die cavity 2.
When producing; first lining, protective sleeve, insulating cylinder and retractor device are assembled (two end faces of protective sleeve and retractor device protection insulating cylinder); then be placed in the die cavity of mould; left push rod, right push rod are tightened fixing; silicon rubber injection is carried out after matched moulds; sizing material injected after 30 ~ 60s(silicon rubber first one-step forming in die cavity, no longer flow), unclamp right push rod 1 ~ 4mm(and determine depending on shaping length).In high temperature vulcanized process, insulating cylinder can promote retractor device after expanding and move right, and this has enough space operations after allowing insulating cylinder expand, and this avoid the generation of the phenomenon of explosion.After reaching regulation cure time, composite sheath just can take out, and completes molding procedure.Whole process operation simply, easily controls, and product percent of pass is high.
In addition, because protective sleeve and retractor device fit tightly with insulating cylinder both ends of the surface respectively, silicon rubber can not enter in insulating cylinder and can not enter into the contact surface of insulating cylinder and lining in injection process.Simultaneously, the excessive glue groove 11 be connected with die cavity 2 is provided with at the left end of die cavity 2, unnecessary sizing material then flows out in excessive glue groove 11, when can prevent from like this injecting, unnecessary sizing material impacts distortion to left and right push rod under the injection pressure of up to a hundred tons, improves the mold use life-span.And reasonably judged by the sizing material discharge of observing in excessive glue groove 11 and control the injection volume of sizing material, avoiding the waste of sizing material.
