Detailed description of the invention
With the following Examples the utility model is further described.
The detailed description of the invention of a kind of thimble automatic reset mechanism of the present utility model, as depicted in figs. 1 and 2, comprise the thimble main body 6 being fixed on line position 1, line position 1 is located at die 2 and can be relatively slided by die 2, die 2 is provided with the through hole 21 passing for thimble main body 6 and slide, during mould die sinking, line position 1 is to the left and right sides transverse shifting of die 2, and thimble main body 6 moves with line position 1 simultaneously, line position 1 will make to be separated with product 4 into the regrinding-material in solation road 3 to movement outside die 2, is convenient to follow-up thimble main body 6 and moves up and to be ejected into solation road 3 by regrinding-material.
As shown in Figure 3, described thimble main body 6 comprises sleeve 7 and to be built in described sleeve 7 and first thimble 8, second thimble 9 that can slide relative to described sleeve 7, one end of described first thimble 8 be connected to be opened in line position 1 enter solation road, the other end of described first thimble 8 supports one end of described second thimble 9, the other end of described second thimble 9 abuts ejector retainner plate 13, and described first thimble 8 is arranged with spring 10.During mould die sinking, line position 1 will cause being separated with product 4 into the regrinding-material in solation road 3 to transverse shifting outside die 2, then ejector retainner plate 13 moves up and promotes the second thimble 9 and moves up, and then second thimble 9 promote the first thimble 8 and move up, first thimble 8 is directly supported into the regrinding-material in solation road 3, the spring 10 being simultaneously set in the first thimble 8 is compressed, until the regrinding-material entered in solation road ejects 3 by the first thimble 8, subsequently, ejector retainner plate 13 retreats and resets, first thimble 8 carries out automatically reseting action at the elastic force moved downward of spring 10, second thimble 9 also moves downward and carries out automatically reseting action under the promotion of the first thimble 8 simultaneously, until the second thimble 9 abuts the ejector retainner plate 13 after resetting.Because thimble main body 6 is separated with ejector retainner plate 13, thimble main body 6 is with after line position 1 transverse shifting, ejector retainner plate 13 can promote thimble main body 6 again and move upward, and then eject regrinding-material handle, thimble automatic reset mechanism of the present utility model can not only make the thimble main body 6 be positioned in line position 1 can eject regrinding-material handle, and can the action that automatically resets be completed, reset accurately, structure is simple simultaneously.
Further, described line position 1 is fixed in one end of described sleeve 7, the other end of described sleeve 7 is provided with fixed block 11, described second thimble 9 is arranged in described fixed block 11 and can slides relative to described fixed block 11, fixed block 11 plays guide effect to the second moving up and down of thimble 9, and prevents the second thimble 9 from coming off in sleeve 7.
Further, one end that described second thimble 9 and described first thimble 8 are supported is provided with the second positive stop lug boss 91, and the limited step of described fixed block 11 is undertaken spacing by the displacement of described second positive stop lug boss 91 to described second thimble 9.
In the present embodiment, limited step 71 in cylinder is provided with in described sleeve 7, one end that described first thimble 8 and described second thimble 9 are supported is provided with the first positive stop lug boss 81, and limited step 71 in described cylinder is supported in one end of described spring 10, and the other end of described spring 10 supports described first positive stop lug boss 81.
Further, the compression slide block 12 for compressing described spring 10 is also provided with between described spring 10 and described first positive stop lug boss 81, compression slide block 12 makes spring 10 also be in compressive state at non-top delivery port material under 3 states always, can guarantee that the reset of the first thimble 8, second thimble 9 is accurate like this, put in place.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
