Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, foldable type mould under a kind of U-shaped backboard, comprise module 1 and correspondence and be arranged at lower module 2 below described upper module 1, wherein, described upper module 1 comprises upper bolster 14, cope match-plate pattern 12 and upper liner plate 11 from top to bottom, and connect successively, described cope match-plate pattern 12 is protruded in described upper liner plate 11 bottom surface; Described lower module 2 comprises lower liner plate 21, male template 22, lower bolster 23 and die shoe 25 from top to bottom, and connects successively, described lower liner plate 21 offers the annular forming tank 211 matched with described cope match-plate pattern 12 size; Elastic positioning device 6 is provided with between described upper module 1 and lower module 2.
Described elastic positioning device 6 comprises alignment pin 61 and corresponding locating hole 63, described locating hole 63 is arranged at the bottom of described upper liner plate 11, described alignment pin 61 is through described lower liner plate 21, described alignment pin 61 bottom surface is provided with support spring 62, conflict described die shoe 25 in the bottom surface of described support spring 62, the bottom of described alignment pin 61 up extrudes described lower liner plate 21; Buffer spring 64 is provided with bottom described locating hole 63; Described lower liner plate 21 is fixedly connected with male template 22, is provided with stage clip 3 between described lower liner plate 21 and die shoe 25, is provided with stage clip 3 between described upper liner plate 11 and upper bolster 14, increases the cushioning effect in the course of work and punching press stability.
Under buffer spring nature extended configuration, the length between buffer spring outer end to locating hole outer face is that described alignment pin stretches out 1/2 ~ 2/3 of face length, shrinks generation elastic force when enabling described alignment pin 61 insert described locating hole 63.
Be fixedly installed cushion block 15 above described upper bolster 14, and be fixedly installed mounting plate 16 above described upper cushion block 15; Be fixedly installed lower cushion block 26 below described die shoe 25, and be fixedly installed bottom plate 27 below described lower cushion block 26, easy disassembly, more mold exchange.
Be provided with upper padding plate 13 between described cope match-plate pattern 12 and upper bolster 14, between described lower bolster 23 and die shoe 25, be provided with lower bolster 24, upper bolster 14 described in impulsive force macrolesion and die shoe 25 can be prevented.
In use, when upper module 1 down moves, alignment pin 61 inserts locating hole 63, upper module 1 continues down to move, upper surface and buffer spring 64 outer end of alignment pin 61 contact, and buffer spring 64 and support spring 62 all shrink and produce elastic force, for the motion of upper liner plate 11 brings double buffering.And, support spring 62 shrinks and the power of alignment pin 61 bottom squeeze male template 22 is reduced gradually, namely the support force of support spring 62 pairs of male template 22 reduces gradually, liner plate 21 and male template 22 under stage clip 3 under described lower liner plate 21 and support spring 62 common support, lower liner plate 21 and male template 22 are for being fixedly connected with, when support spring 62 pairs of male template 22 support forces reduce gradually, stage clip 3 pressure under described lower liner plate 21 becomes large gradually and shrinks generation elastic force, for bringing buffering when upper liner plate 11 contacts male template 22.It is faster that upper module 1 moves downward speed, and the cushioning effect that the stage clip 3 under described lower liner plate 21 brings to upper liner plate 11 is more remarkable.Before upper liner plate 11 contacts male template 22, for buffer spring 64, support spring 62 coordinate the double cushioning effect of generation; When upper liner plate 11 contacts male template 22, the cooperation of buffer spring 64, support spring 62, stage clip 3 produces triple buffer effect, and support spring 62 pairs of male template 22 support forces have a progressive formation, punching press stability greatly improves, improve yield rate, and reduce grinding tool wearing and tearing, increase the service life.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
