[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of spectacle frame mould structure, comprise front mould bases 1 and rear mould bases 2, be provided with between described front mould bases 1 and rear mould bases 2 for shaping front template 3, rear pattern plate 4 and the lens frame core rod 5 of spectacle-frame, be provided with between described lens frame core rod 5 and rear pattern plate 4 and make the rotary motion and deviate from the stripper apparatus 6 of spectacle-frame 100 again of the first rectilinear motion of lens frame core rod 5 when die sinking.When die sinking, stripper apparatus 6 makes the first straight forward movement of lens frame core rod 5, and when moving to setpoint distance, stripper apparatus 6 makes the relative spectacle-frame 100 of lens frame core rod 5 rotate, warpage is there is in lens frame core rod 5 in the process of rotating, because the spectacle-frame 100 of injection mo(u)lding has elasticity, thus spectacle-frame 100 is ejected and the demoulding, the spectacle-frame 100 after the demoulding is without any pulling equivalent damage, product quality is guaranteed, and mould structure is simple, easily manufactured, with low cost.
As shown in Figures 2 to 4, for the push rod 61 that promotes lens frame core rod 5 and spectacle-frame 100 rectilinear motion and the through hole 62 be located on lens frame core rod 5 when described stripper apparatus 6 is included in die sinking, the gag lever post 63 be fixedly connected with rear pattern plate 4 is equipped with in described through hole 62, that the end of described gag lever post 63 is provided with arc and spacing 64 that when touching with top, through hole 62 edge, lens frame core rod 5 is rotated.
As shown in Figures 2 to 4, described lens frame core rod 5 side is provided with push rod 61 to the boss 65 touched, described boss 65 offers the boss through hole 66 running through lens frame core rod 5, described push rod 61 be provided with through boss through hole 66 energy relative to lens frame core rod 5 move and in 5 demoulding of lens frame core rod time prevent lens frame core rod 5 from dropping out the locating part 67 of spectacle-frame mould structure.
As shown in Figure 2, Figure 4 shows, described locating part 67 comprises the limited post 671 be connected with push rod 61 end, and the other end of described limited post 671 is provided with evagination in the protuberance 672 at boss through hole 66 edge.
As shown in Figure 3, Figure 4, described boss 65 is provided with the inclined-plane 651 when die sinking for top, push rod 61 end pressure.When spectacle-frame 100 demoulding, the end of push rod 61 withstands on inclined-plane 651, when lens frame core rod 5 and spectacle-frame 100 rectilinear motion reach setpoint distance, lens frame core rod 5 relatively spectacle-frame 100 rotates, and push rod 61 withstands on inclined-plane 651, lens frame core rod 5 can be made more easily to rotate, make lens frame core rod 5 easier from warpage in spectacle-frame 100.
As shown in Figure 1 and Figure 2, the buffer bar 7 be provided with in described front template 3, is provided with spring 8 between described buffer bar 7 and front mould bases 1.
As shown in Figure 1 and Figure 2, the guide post 9 when matched moulds or die sinking for leading is provided with in described front template 3 and rear pattern plate 4.
As shown in Figure 3, Figure 4, multiple pilot pin 10 making lens frame core rod 5 locate when matched moulds is provided with between described lens frame core rod 5 and rear mould bases 2.Pilot pin 10 can make the location of lens frame core rod 5 more accurate, makes the size of injection moulding spectacle-frame 100 out more accurate.
Operation principle:
During die sinking, push rod 61 is to sinciput lens frame core rod 5, now lens frame core rod 5 is still in spectacle-frame 100, both are together along the axis straight forward movement of gag lever post 63, when through hole 62 edge on lens frame core rod 5 touches spacing 64, spacing 64 pairs of lens frame core rods 5 apply resistance, and now push rod 61 still continues to sinciput lens frame core rod 5, at this moment the surface contacted with through hole 62 due to spacing 64 is cambered surface, rotate so lens frame core rod 5 againsts spacing 64, simultaneously again because spectacle-frame 100 has elasticity, therefore, there is warpage thus spectacle-frame 100 ejected and the demoulding in lens frame core rod 5.When lens frame core rod 5 is attached on spacing 64, push rod 61 heads on inclined-plane 651, thus lens frame core rod 5 is more easily rotated.After spectacle-frame 100 ejects, the protuberance 672 due to limited post 671 end protrudes from the edge of boss through hole 66, so lens frame core rod 5 can be blocked by protuberance 672, can not drop out in mould.When push rod 61 promotes lens frame core rod 5, the bumper post 7 that the locating part 67 moved with push rod 61 promotes in front template 3 moves, and spring 8 is compressed, and now travelling forward of push rod 61 have also been obtained buffering, avoids that impact is too large causes damage to product.
