Abstract
The utility model discloses a floating mold for producing a rubber product. The floating mold comprises an upper mold body (1) and a lower mold body (2), wherein a plurality of convex mold subassemblies (3) are arranged on the upper mold body (1); a plurality of cavities (4) are arranged on the lower mold body (2); the convex mold subassemblies (3) are matched and connected with the cavities (4) and fixedly connected with the upper mold body (1) through fastening bolts (5); each convex mold subassembly (3) comprises an annular outer mold (31) and a cylindrical inner mold (32); the cylindrical inner mold (32) is embedded into the annular outer mold (31); a rubber elastomer (6) is arranged between the upper mold body (1) and the convex mold subassemblies (3). By adopting the floating mold, the problems that a part of spare parts generate slitter edges in the practical working process due to the precision difference in size in the traditional combined injection mold, so that not only is the product quality affected, but also the production cost of an enterprise is improved are effectively solved.
Description
Technical field
The utility model relates to rubber production technical field, is specifically related to a kind of rubber production floating die assembly.
Background technology
In rubber production process, normally block rubber is sulfided in injection mold to liquid, then moulding in die cavity, traditional rubber component manufacturing enterprise in process of production, conventionally carry out injection mo(u)lding with upper and lower assembling die, be that the concave die cavity that patrix patrix is provided with multiple punch assemblies and counterdie patrix matches, but in the actual manufacture process of mould, to ensure that all punch are the same with the size do of die, must there are some difference in size, these difference in size will produce flash in actual injection moulding process, thereby generation slitter edge, the material that should be slitter edge just becomes grog after heating, cannot be recycled, cause the raising of enterprise's production cost, .
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rubber production floating die assembly, the utility model efficiently solves conventional combination injection mold, due to the precision difference of depositing dimensionally, in practical work process, can cause part parts to produce slitter edge, not only affect the quality of product, and improved the problem of the production cost of enterprise.
The utility model is achieved through the following technical solutions:
A kind of rubber production floating die assembly, comprise upper die body (1), lower mold body (2), upper die body (1) is provided with multiple punch assemblies (3), lower mold body (2) is provided with multiple die cavities (4), punch assemblies (3) matches and is connected with die cavity (4), it is characterized in that: described punch assemblies (3) is fixedly connected with upper die body (1) by fastening bolt (5), described punch assemblies (3) comprises circular external mold (31) and cylindric internal mold (32), cylindric internal mold (32) is embedded in circular external mold (31), between upper die body (1) and punch assemblies (3), be provided with rubber elastomer (6).
The further improvement project of the utility model is:
Described upper die body (1) is provided with fixed via (11), fastening bolt (5) is fixed adjustable connection with circular external mold (31) and cylindric internal mold (32) respectively by fixed via (11), is coated with the pre-gland (7) that elastomeric material is made on fastening bolt (5).
The utility model compared with prior art, there is following advantage: the utility model by arranging elastic rubbery body between upper die body and punch, and punch assemblies is split-type design, in the actual use procedure of mould, individual punch assemblies can regulate the fit dimension with die voluntarily, ensure that punch assemblies coordinates with die cavity tight, pre-gland can prevent rubber problem along the outside flash of screw thread in sulfidation, not only improve the quality of product, but also reduced the production cost of enterprise.
Brief description of the drawings
Fig. 1 is the utility model upper die body structural representation;
Fig. 2 is the utility model lower mold body structural representation.
Detailed description of the invention
As Fig. 1, shown in 2, the utility model comprises upper die body 1, lower mold body 2, upper die body 1 is provided with multiple punch assemblies 3, lower mold body 2 is provided with multiple die cavities 4, punch assemblies 3 matches and is connected with die cavity 4, described punch assemblies 3 is fixedly connected with upper die body 1 by fastening bolt 5, described punch assemblies 3 comprises circular external mold 31 and cylindric internal mold 32, cylindric internal mold 32 is embedded in circular external mold 31, between upper die body 1 and punch assemblies 3, be provided with rubber elastomer 6, described upper die body 1 is provided with fixed via 11, fastening bolt 5 is fixed adjustable connection with circular external mold 31 and cylindric internal mold 32 respectively by fixed via 11, on fastening bolt 5, be coated with the pre-gland 7 that elastomeric material is made, pre-gland 7 is arranged between the through hole on fixed via 11 and the rubber elastomer 6 of fastening bolt 5 and upper die body, .
In actual production process, punch assemblies 3 can regulate the contact area with die cavity 4 as required automatically, has improved the sealing effectiveness of each punch assemblies 3 with die cavity 4, and in Vulcanization Process of Rubber, slitter edge rate greatly reduces.
In sum, the utility model has reached foregoing invention object.
