Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
nullAs shown in Figures 1 to 7,A kind of injection mold facilitating material strip to pull out,Including front mould and rear mold,This front mould includes the panel 1 set gradually from front to back、Stripper plate 2 and front template 3,This rear mold includes base plate 4、Two the mould feet 5 being vertically installed on front side of base plate 4、The rear pattern plate 6 being horizontally placed on two mould feet 5 and the push pedal 7 between rear pattern plate 6 and front template 3,It is provided with top board 8 between two mould feet 5,Top board 8 is provided with thimble 9,Push pedal 7 is provided with material strip 10,Described thimble 9 is through described rear pattern plate 6,And this thimble 9 withstands on material strip 10,On the rear side of described push pedal 7, push rod 11 is installed,This push rod 11 passes rear pattern plate 6 and stretches out in the trailing flank of rear pattern plate 6,Described top board 8 can act on the rear end of this push rod 11,Described push rod 11 is provided with in two grooves 111 front and back arranged,The side of described rear pattern plate 6 is provided with a ripple Lunella coronata silk 12 being perpendicular to push rod 11,One end being provided with ripple pearl 123 of this ripple Lunella coronata silk 12 is supported on described push rod 11.It is additionally provided with locking nut 13, so that ripple Lunella coronata silk 12 to be locked on the outer end of described ripple Lunella coronata silk 12.Specifically, ripple Lunella coronata silk 12 is to be made up of housing 121, spring 122 and ripple pearl 123, wherein, housing 121 has a receiving chamber, and this receiving intracavity is provided with spring 122 and the ripple pearl 123 being positioned on spring 122 outer end, spring 122 can promote ripple pearl 123 to move, when ripple pearl 123 is squeezed, can be internal mobile to the containing cavity of housing 121, and compression spring 122, when extruding releases, spring 122 can promote ripple pearl 123 to be displaced outwardly.
Furtherly, top board 8 is provided with limited block 14, and the action that ejects to top board 8 carries out spacing.
Furtherly, stripper plate 2 being fixed with a guide pin 15, this guide pin 15 sequentially passes through front template 3, push pedal 7, rear pattern plate 6 and top board 8 backward.During die sinking, front mould can move under the restriction of this guide pin 15 guides.This guide pin includes ailhead 152 and post 151, and described front template 3 is provided with shoulder hole 31, and after die sinking, the ailhead 152 of guide pin 15 is resisted against on the cascaded surface of shoulder hole 31.
Furtherly, in the present invention, top board 8 is equipped with the guide pillar 16 being fixed on base plate 4.Top board is movable under the restriction of guide pillar guides.
During work, as shown in Figure 3 and Figure 4, front mould is opened, panel 1 and stripper plate 2 move forward, and open in advance, drive guide pin 15 to move, until the ailhead 152 of guide pin 15 is resisted against on the cascaded surface of shoulder hole 31 of front template 3, thus under the drive of guide pin 15, front template 3 moves, after current template 3 moves into place, under under the effect of outside push rod, top board 8 ejects, and top board 8 drives push rod 11 and thimble 9 to eject, and push pedal 7 is ejected by push rod 11.When push rod 11 and push pedal 7 are not ejected, in the groove 111 of the forward position that the ripple pearl 123 of ripple Lunella coronata silk 12 is stuck in push rod 11.When push rod 11 is ejected by top board 8, the push rod 11 extruding to the ripple pearl 123 of ripple Lunella coronata silk 12, ripple pearl 123 is made to depart from the groove 111 of forward position of push rod 11, and it is internal mobile to ripple Lunella coronata silk 12, after the groove 111 of the position rearward on push rod 11 runs into the ripple pearl 123 of ripple Lunella coronata silk 12, spring 122 in ripple Lunella coronata silk 12 promotes ripple pearl 123 to snap in the groove 111 of the position rearward on push rod 11 so that push pedal 7 has ejected.Then, as shown in Figure 5 and Figure 6, top board 8 can be return, and drives thimble 9 to return so that thimble 9 is no longer interfere with the pull-out of material strip 10.After top board 8 and thimble 9 are return, push pedal 7, under the effect of ripple Lunella coronata silk 12, stops motionless, now may utilize and automatically draws material strip mechanism to be pulled out by material strip.
The invention have the advantages that the present invention passes through the cooperation of top board and push rod and ejecting push plate, top board and thimble resetted, and the push pedal after ejecting stops motionless under the effect of ripple Lunella coronata silk, material strip can be drawn out.This injection mold structure is simple, it is possible to achieve push pedal stops and pulls out material strip when push pedal stops, and facilitates the pull-out of material strip, it is achieved that take out the purpose of multimode product in an injection cycle, and, whole motion ratio is relatively reliable, and production efficiency is high.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
