Abstract
The invention provides a mold easy to open for machining a dumbbell-shaped vulcanized rubber test piece, which belongs to the technical field of a mold. A cylindrical upper mold plate and a cylindrical boss are respectively matched with a cavity of a cylindrical sleeve; a mold opening device comprises a cylindrical cavity barrel and a solid cylinder, the outer diameter of a cylindrical upper mold base and the outer diameter of a cylindrical base are respectively less than the inner diameter of the cylindrical cavity in the cylindrical cavity barrel, and the outer diameter of the cylindrical sleeve is equal to that of the cylindrical cavity barrel. After the vulcanization is completed, a forming head, the cylindrical sleeve and the cylindrical base are disassembled and arranged on the cylindrical cavity barrel of the mold opening device, and pressure is applied to the forming head, so that the cylindrical base and a rubber material are collectively separated from a mold cavity. Two surplus non-separated devices are overturned, and are arranged on the cylindrical cavity barrel of the mold opening device, and pressure is applied to the forming head by utilizing the solid cylinder, so that the forming head is separated from the cylindrical sleeve, and the mold opening is completed. The mold is simple and convenient to open, and the test piece is not damaged.
Description
Technical field
The present invention relates to a kind ofly for processing the easy die-sinking die of dumbbell shape vulcanized rubber test specimen, belong to technical field of mold.
Background technology
Rubber is the high resiliency polymeric material with reversible deformation, is widely used in and manufactures in tire, sebific duct, adhesive tape, cable and other rubbers.The sulfuration of rubber has a great impact the performance of rubber, and over cure and the physical property of rubber parts and the physical property of optimum cure rubber parts of owing sulphur have very large gap, in over cure and the application afterwards of the rubber parts of owing sulphur, may exist some problems.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 vulcanization of rubber at present is generally comprised of two parts or three parts, exists the problem of difficult molding after sulfuration.
Summary of the invention
The object of the invention is the problem existing in order to solve above-mentioned prior art, the mould of the vulcanization of rubber at present is generally comprised of two parts or three parts, exists the problem of difficult molding after sulfuration.And then provide a kind of for processing the easy die-sinking die of dumbbell shape vulcanized rubber test specimen.
The object of the invention is to be achieved through the following technical solutions:
A kind of for processing the easy die-sinking die of 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 the external diameter of cylindrical sleeve and cylindrical cavity cylinder equates.
When the present invention uses, utilize vulcanizing press vulcanized rubber material, first the combination of cylindrical base and cylindrical sleeve is positioned on vulcanizing press, in cylindrical sleeve die cavity, add rubber mixedly, then place moulded head, the press cure of heating.
After having vulcanized, will vulcanize three (moulded head, cylindrical sleeve and cylindrical base) cover and take off, be positioned on the cylindrical cavity cylinder of die-sinking device, on moulded head, exert pressure, and make cylindrical base together separated with die cavity with sizing material.Unsegregated two devices of upset residue, are positioned on the cylindrical cavity cylinder of die-sinking device, utilize solid cylinder to exert pressure and make it separated with cylindrical sleeve to moulded head, complete die sinking.
Finally utilize standard cut-off knife that sheet vulcanization of rubber part is cut into dumbbell shape test specimen, for test.
A kind of easy die-sinking die that the present invention proposes is comprised of five parts, comprises after three part moulds that sulfidation is used and sulfuration the two-piece-dress die-sinking device for molding.By after sulfuration for the two-piece-dress die-sinking device of molding, well solved the problems such as molding difficulty is large, molding effort.Whole process is simple, easy operating.Die sinking is simple and convenient, and can not damage test specimen.
