Abstract

The utility model relates to a multi-layer seal ring rubber pressing die, which belongs to the tooling die for pressing a seal ring as a rubber block of the outgoing line of a motor junction box, and in particular relates to a die manufacturing structure for pressing a seal ring rubber workpiece with a multi-layer inner ring. The multi-layer seal ring rubber pressing die consists of an upper die (1), an intermediate die (2), a lower die body (3), a cylindrical pin (4), an inner lower die sleeve (5), an intermediate lower die sleeve (6), a secondary intermediate lower die sleeve (7), an outer lower die sleeve (8), a pin shaft (9), and a support sleeve (10). The utility model can be used for pressing a five-layer seal ring rubber workpiece, the five layers of rubber thin walls on the inner ring of the pressed seal ring rubber workpiece conform to the size requirements, and the rubber layer on each thin wall can not be damaged.

Description

Multi-layer sealed circle rubber mold

Technical field:

Multi-layer sealed circle rubber mold is a kind of moulds of industrial equipment of compacting rubber sealing ring product, particularly a kind of moulds of industrial equipment of the stifled multi-layer sealed circle rubber part of compacting explosion separation motor terminal box outlet glue.

Background technology:

What the stifled sealing ring of connection box for motor outlet glue adopted is that rubber part assembles, the mode of connection difference that need use according to each mining motor, the cable dimension difference that adopts, sealing ring inner ring size are also different, and a circle, two circles, three circles, four circles, five circles, six circles etc. are arranged.Because the thin-walled of every circle has only 0.2～0.3mm, relatively more difficult always in mould manufacturing and the product moulding. and the product that always can only be pressed into before this more than two products that enclose, three circles fails to realize always; It is high that the stifled sealing ring of connection box for motor outlet glue is made the mould repair rate, and these reasons are perplexing production and manufacturer always; Rubber part belongs to soft goods and the inner ring wall is very thin, and air pressure is arranged moving back Mo Shinei, and thin-walled is torn, and can not adopt rightabout to move back mould on the mould mode moving back, and the mould structure of old mould does not overcome the problems referred to above.

Summary of the invention:

The multi-layer sealed circle rubber mold of the utility model goal of the invention is: manufacture and design a kind of rubber sealing ring product that can suppress smoothly more than five circles, to adapt to the needs of explosion separation motor usefulness terminal box outlet cable seal circle under the coal mine.

The multi-layer sealed circle rubber mold of the utility model is achieved in that by patrix, middle mould, lower mold body, straight pin, interior lower die-sleeve, middle lower die-sleeve, inferior middle lower die-sleeve, outer lower die-sleeve, mandrel and support set to be formed; Patrix and the little gap of middle mould cone match, middle mould and the little gap of lower mold body cone match, mandrel and the little matched in clearance of outer lower die-sleeve, inferior middle lower die-sleeve and the little matched in clearance of outer lower die-sleeve, middle lower die-sleeve and time middle little matched in clearance of lower die-sleeve, interior lower die-sleeve and the little matched in clearance of middle lower die-sleeve; With outer lower die-sleeve, inferior in lower die-sleeve, middle lower die-sleeve and interior lower die-sleeve fit together and put into lower mold body, cooperation seam on the lower mold body and the little matched in clearance of interior lower die-sleeve; Support set is put into lower mold body and is supported counterdie, with straight pin insert support in the hole in the lower mold body time in lower die-sleeve and outer lower die-sleeve; Straight pin inserts in the hole of lower mold body, and middle die sleeve is on the conical surface round platform on the lower mold body, and patrix is equipped with the cooperation seam of mould in the aligning; Process the conical surface dome platform that matches with middle mould on the patrix, two round seams of the conical surface that cooperates the circle seam to be processed into and to match up and down of middle mould with the upper die and lower die body; Process the conical surface dome platform that matches with middle mould on the lower mold body; The centre position is bored two circular holes and is used for inserting straight pin on the lower mold body, interior lower die-sleeve, middle lower die-sleeve, inferior in lower die-sleeve and outside all be drilled with air-vent on the lower die-sleeve die cavity also all arranged; On mandrel, processed die cavity.

The multi-layer sealed circle rubber mold of the utility model work process: the rubber mass that scale is good is put into mould, and a whole set of mould that installs rubber mass pushes and carries out on the hot pressing lathe after the compacting regular hour, moving back mould to pressing compacting; Mold integral is turned around, mandrel is backed off earlier, then, in layer each counterdie thin-walled cover is withdrawed from from inside to outside, the sealing ring product that finally suppresses is stayed in the middle mould, patrix is separated with middle mould, and the sealing ring product drops out automatically, and so far a complete multi-turn sealing ring product is just suppressed successfully.

The beneficial effect of the multi-layer sealed circle rubber mold of the utility model: the rubber sealing ring pressing mold after improving, overcome the problem that thin-walled is torn easily, suppress the above rubber sealing ring product of inner ring five circles, guaranteed manufacturing schedule, solved the high problem of mould repair rate, adapt to the needs of producing, created benefit.
