Abstract

A self-pressurized and self-heated large-diameter rubber goods curing device comprises circular channels for heating on an upper cover 1, a lower cover 8, an outer mold 2 and an inner mold 3. A product 12 is compressed tightly by a matched conical surface B passing through the outer mold 2 and between the upper and the lower covers 1, 8 and by a matched conical surface C passing through the inner mold 3 and between an upper and a lower conical plates 4, 9 through fastening fasteners 6, 7. The self-pressurized and self-heated large-diameter rubber goods curing device, characterized by simple structure, small size, convenient assembly and disassembly, and quick heat transmission, is adaptable to vulcanization of large-diameter rubber goods and rubber goods of square, rectangular, ball-like, plate-like shapes.

Description

Self-pressurized heating vulcanization plant of large-diameter rubber product

Technical field

The utility model relates to a kind of large caliber rubber goods vulcanization plant, particularly self-pressurized heating vulcanization plant of large-diameter rubber product.

Background technology

The rubber sulfuration has two kinds of methods usually.A kind of is to adopt the semi-finished product fit type is packed into behind the mould, through hydraulic steam or the pressurization of Electrothermal plate vulcanizer, heating, through the sulfidation of certain hour, has both become finished product again.For the heavy caliber product, as the large caliber rubber goods more than the DN1200 millimeter, in sulfidation, not only need large-scale hydraulic type vulcanizing press and handler, and, cause cure time long because heat conduction velocity is slow, production efficiency is low; Another kind is, with semi-finished product fit type a kind of self-pressurization heated type vulcanization plant of packing into, (as shown in Figure 1) this device is on loam cake 1, lower cover 8, external mold 2, be processed with the circular passage that is used to heat usefulness, 10,14,11 provide rubber to vulcanize needed heat by feed steam or electric heater in 10,14,11.Though this method increases than preceding a kind of method production efficiency, but because internal mold 3 does not have the circular passage heating, only outer mould 2 and upper and

lower cover

1,8 conduct heat, make the inside and outside glue curingprocess rate of rubber inconsistent, and cure time is also influenced, it is aging also to be easy to generate simultaneously outer glue over cure, and interior glue is owed the sulphur performance and do not reached requirement.

Summary of the invention

The utility model purpose provides a kind of self-pressurized heating vulcanization plant of large-diameter rubber product, it is applicable to the vulcanization process of heavy caliber such as the rubber more than the DN1200 millimeter, the formula large caliber rubber goods vulcanization plant that replaces mould and large plate vulcanizer and original self-pressurization heating, the investment of equipment mould is greatly reduced, enhance productivity the rate of reducing the number of rejects and seconds.

The utility model self-pressurized heating vulcanization plant of large-diameter rubber product is realized by following scheme: it is made up of loam cake 1, lower cover 8, external mold 2, internal mold 3, last cone-plate 4, following cone-plate 9, securing member 6 and securing member 7, between loam cake 1 and lower cover 8, external mold 2 is housed, internal mold 3 is loaded in the external mold 2, by securing member 6 loam cake 1, lower cover 8 respectively are connected with external mold 2, will go up cone-plate 4, descend cone-plate 9 respectively to be connected with internal mold 3 by securing member 7.Respectively have

circular passage

10,11,13,14 on external mold 2, internal mold 3, upper and

lower cover

1,8, feeding steam or electric heater heat in the circular passage; Two ends at internal mold 3 all have conical bore, have outer conical surface on upper and lower cone-

plate

4,9, and the two cooperates contact.Two ends at external mold 2 all have outer conical surface, respectively have conical bore on upper and

lower cover

1,8, and the two cooperates contact.Internal mold 3 is combined by plurality of sections, so that pressurization from inside to outside.When using, goods to be vulcanized 12 are opened in the die cavity between internal mold 3 and the external mold 2, screw this securing

member

6,7, by the taper seat of 1,8 of external mold 2 and upper and lower covers and by the taper seat between internal mold 3 and the upper and lower cone-

plate

4,9 with these goods 12 pressurizations; 10,11,13,14 feed steam and electric heater baking from the circular passage.

In sum, heat the circular passage and adopt taper seat to tighten up pressuring method, make its very fast, efficient raising of conducting heat because this vulcanization plant itself has, quality of item is easy to guarantee, this apparatus structure is is simply installed and removed conveniently, compares with mould with adopting large plate vulcanizer, saves investment a lot; Compare with the formula large caliber rubber goods vulcanization plant that adopts original self-pressurization heating and to have improved production efficiency, reduced percent defective.

The specific embodiment

Be illustrated in figure 2 as the above rubber of sulfuration heavy caliber DN1200 millimeter pressurized, heated formula vulcanization plant schematic diagram, goods are the flexible elastomer connector.Between the lower cover 8 of the loam cake 1 of annular and annular, external mold 2 is arranged, internal mold 3 is housed in external mold 2, this internal mold 3 combines as shown in Figure 3 for multistage, by fastener bolt 6 loam cake 1, lower cover 8 are connected with external mold 2, to be gone up cone-plate 4, be descended cone-plate 9 to be connected with internal mold 3 by fastener bolt 7, the conical bore at internal mold 3 two ends cooperates with the outer conical surface C of upper and lower cone-

plate

4,9; The outer conical surface B of external mold 2 cooperates with conical bore on the upper and lower cover 1,8.Screw this

bolt
