Abstract
The present invention provides an easy-to-open dumbbell-type vulcanized rubber specimen processing mold, and belongs to the technical field of a mold. A cylindrical upper mold plate and a cylindrical convex platform are matched with a cavity of a cylindrical sleeve; a mold opening device comprises a cylindrical cavity cylinder and a solid cylinder, the outer diameter of a cylindrical upper mold base and the outer diameter of a cylindrical base are smaller than the inner diameter of the cylindrical cavity of the cylindrical cavity cylinder, and the outer diameter of the cylindrical sleeve and the outer diameter of the cylindrical cavity cylinder are equal. After the completion of the vulcanization, a molding head, the cylindrical sleeve and the cylindrical base are taken off, and placed on the cylindrical cavity cylinder of the mold opening device, pressure is applied to the molding head, and the cylindrical base and a sizing material are together separated from the mold cavity. The remained unseparated two-piece device is turned over, and placed on the cylindrical cavity cylinder of the mold opening device, and by application of the pressure to the molding head by the solid cylinder for separation from the cylindrical sleeve, the mold opening is completed. The mold opening is simple and convenient, and the specimen may not be damaged.
Description
Technical field
The present invention relates to a kind of easy die-sinking die for processing dumbbell shape vulcanized rubber test specimen, belonging to technical field of mold.
Background technology
Rubber is the strong flexible polymer material with reversible deformation, is widely used in and manufactures in tire, sebific duct, adhesive tape, cable and other rubbers.The performance of sulfuration to rubber of rubber has a great impact, and the physical property of the rubber parts of over cure and deficient sulphur and the physical property of optimum cure rubber parts have very large gap, may there are some problems in the application afterwards of the rubber parts of over cure and deficient sulphur.Therefore to study the sulfuration of rubber.In research process, need the dumbbell shape test specimen of rubber to carry out some parameters such as test tensile strength, elongation at break.The mould of the current vulcanization of rubber is generally made up of two parts or three parts, there is the problem of difficult molding after curing.
Summary of the invention
The object of the invention is to solve above-mentioned prior art Problems existing, i.e. the mould of the vulcanization of rubber at present is generally made up of two parts or three parts, there is the problem of difficult molding after curing.And then a kind of easy die-sinking die for processing dumbbell shape vulcanized rubber test specimen is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of easy die-sinking die for processing dumbbell shape vulcanized rubber test specimen, comprise: assembling die and die-sinking device, described assembling die comprises moulded head, cylindrical sleeve and cylindrical base, described moulded head comprises cylindrical upper bolster and cylindrical cope match-plate pattern, cylindrical upper bolster and cylindrical cope match-plate pattern are connected as a single entity up and down, cylindrical sleeve is provided with cavity, the top of cylindrical base is provided with cylindrical boss, and described cylindrical cope match-plate pattern and cylindrical boss all match with the cavity of cylindrical sleeve; Described die-sinking device comprises cylindrical cavity cylinder and solid cylinder, the external diameter of described cylindrical upper bolster and the external diameter of cylindrical base are all less than the internal diameter of cylindrical cavity in cylindrical cavity cylinder, and the external diameter of cylindrical sleeve is equal with the external diameter of cylindrical cavity cylinder.
When the present invention uses, utilize vulcanizing press vulcanized rubber material, first cylindrical base and cylindrical sleeve are combined and be positioned on vulcanizing press, add rubber mixed in cylindrical sleeve die cavity, then place moulded head, carry out temperature-pressure sulfuration.
After sulfuration completes, sulfuration three (moulded head, cylindrical sleeve and cylindrical base) cover is taken off, be positioned on the cylindrical cavity cylinder of die-sinking device, moulded head applies pressure, cylindrical base is together separated with die cavity with sizing material.The unsegregated two pieces device of upset residue, is positioned on the cylindrical cavity cylinder of die-sinking device, utilizes solid cylinder to apply pressure to moulded head and makes it be separated with cylindrical sleeve, complete die sinking.
Finally utilize standard cut-off knife that sheet rubber vulcanization member is cut into dumbbell shape test specimen, for test.
The easy die-sinking die of one that the present invention proposes is made up of five parts, comprises the two-piece-dress die-sinking device for molding after three part moulds of sulfidation and sulfuration.By the two-piece-dress die-sinking device for molding after sulfuration, well solve the problems such as molding difficulty is large, molding effort.Whole process is simple, is easy to operation.Die sinking is simple and convenient, and can not damage test specimen.
