Fig. 2 is the structural representation that the embodiment of mould prepared by the utility model tensile sample; (view of another angle)
Fig. 3 is the structural representation of the profiled sheeting in Fig. 1.
Embodiment
The embodiment of mould prepared by the utility model tensile sample: as Figure 1-3, upper die body 1, the lower mold body 5 that mould comprises stacked on top of one another setting prepared by tensile sample, be provided with two identical profiled sheetings setting up and down between lower mold body 5, upper die body 1, be designated as profiled sheeting 2, compacted under plate 4.Each profiled sheeting is provided with about three the spaced forming tank with specimen shape adaptation.Be provided with central dividing plate 3 between two profiled sheetings, central dividing plate 3 is for keeping apart the forming tank be on different profiled sheetings.In the present embodiment, upper die body 1 is cope match-plate pattern, and lower mold body 5 is lower bolster, is plane below cope match-plate pattern, is plane above lower mold body.Upper die body, lower mold body, profiled sheeting, central dividing plate are tightened together by bolt 6 setting up and down.Bolt 6 lays respectively at the position at four angles of upper die body.
Be formed with the forming cavity for shaping sample between upper die body 1, lower mold body 5, profiled sheeting, in the present embodiment, upper die body 1, upper profiled sheeting 2, central dividing plate 3 form upper forming cavity, and central dividing plate 3, compacted under plate 4, lower mold body 5 form compacted under chamber.The sprue gate for pouring into a mould sample material be communicated with each forming cavity is provided with between upper die body 1, lower mold body 5.Forming tank be a side opening and the open slot 41 be communicated with sprue gate, open slot 41 is in dumbbell shaped.The side being positioned at opening of profiled sheeting has the bell being communicated with each open slot, and bell 41 becomes large by open slot bottom land 44 gradually to the direction of its opening.Four angles on profiled sheeting are provided with the bolt hole 43 passed through for bolt.
For ensureing the dimensional requirement of the size conforms laboratory sample of the forming tank of this mould, the surface roughness requirements of above-mentioned upper and lower forming cavity is not less than 1.6.Forming cavity due to this mould is used to casting epoxy resin material, therefore, ensure certain sealing, by improving the flatness of cope match-plate pattern, lower bolster, central dividing plate, profiled sheeting, when tightening fastening bolt, by the snap-in force of each bolt, ensure certain sealing of mould.In the present embodiment, be bolted, make mould installation, convenient disassembly, be also convenient to cleaning; In other embodiments, connection between each parts of mould is also by compressing structure, U-shaped snap ring can be utilized to coordinate the version of adjustment bolt, U-shaped snap ring is stuck on upper and lower die body, the top of U-shaped snap ring is provided with threaded hole, and adjustment bolt thread is arranged on U-shaped snap ring, and rotating adjustment bolt namely can compaction mold, unscrew adjustment bolt, can dismantle between each parts of mould.
The utility model mould when concrete use, (1), first by epoxy resin and hardening agent, promoter and thinning agent, configure mixture of epoxy resins according to a certain percentage; (2), to mixture of epoxy resins vacuumize, to discharge the gas in feed liquid; (3), at the appropriate release agent of the surface spraying of the forming cavity of the utility model mould, after coated, sealing, matched moulds is fastened by bolts; (4), under vacuum compound is poured in mould along the sprue gate of mould, continues feed supplement, until forming cavity region feed liquid is full of; (5) mould is positioned in baking oven heats; (6) after injection body to be poured is solidified completely, die sinking is carried out, the sample that careful taking-up is obtained; (7) sample obtained is put into baking oven, carry out Post RDBMS by specific process conditions.
By molded mode, directly can make the drawn samples of standard shape, save later stage machining processes, reduce human and material resources investment, avoid the dust produced in machining process to impact the healthy of operating personnel.Improve sample formation qualification rate, avoid people to be the size, verticality, the roughness equal error that cause, make laboratory test results more accurate.The mould structure of Flat stacked makes mould easy for installation, and after die sinking, sample is directly outside exposed, and the easy demoulding more easily ensures the form accuracy of molded samples.
In the present embodiment, two profiled sheetings are set, and multiple forming tank is set on each profiled sheeting, make once-cast can shaping multiple sample.Efficiency is high, and same batch produce the sample gone out between otherness also relatively little.In other embodiments, can a profiled sheeting be only set between upper and lower template, between profiled sheeting, cope match-plate pattern, lower bolster, be formed into die cavity.In other embodiments, the forming tank on profiled sheeting can only arrange one, one-shot forming sample.
