Abstract
The utility model provides a runner shutoff valve structure which enables a shutoff valve to be conveniently taken out even when glue overflowing happens to a gap between the shutoff valve and a mold core, ensures the disassembling progress of a mold and improves the production efficiency of the mold. The structure comprises the mold core, a rubber and a shutoff end part, wherein the shutoff end part is positioned inside one side of a shutoff hole groove in the mold core; one end of the shutoff end part convexes inside the runner. The structure is characterized in that a T-shaped groove is formed in the other end of the shutoff end part; a T-shaped column is clamped inside the T-shaped groove; a threaded structure is arranged at the lower part of the T-shaped column; a limiting column is positioned on the other side of the shutoff hole groove; an inner threaded through hole is formed in the limiting column; the threaded structure of the T-shaped column is in threaded connection with the threaded through hole inside the limiting column; a limiting block is arranged on the outer side of the limiting column, and is clamped inside a positioning chamber of the mold core; another gap is formed between the inner side end surface of the limiting column and the other end surface of the shutoff end part.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of flow passage interception valve arrangement.
Background technology
Runner throttle-valve structure in the die of existing mould, it cannot flow out by die the glue in runner by shutoff valve structure, when producing excessive glue in the gap between shutoff valve and die, flow passage interception valve is difficult for taking out, affect the dismounting progress of whole mould, make the production efficiency of mould low.
Summary of the invention
The utility model provides a kind of flow passage interception valve arrangement, and it makes to produce while overflowing glue in the gap between shutoff valve and die, and shutoff valve also can take out easily, guarantees the dismounting progress of mould, improves the production efficiency of mould.
A kind of flow passage interception valve arrangement, its technical scheme is such: it comprises die, runner, the end of damming, the described end of damming is positioned at a side of the hole slot that dams of described die, its one end evagination is in described runner, it is characterized in that: described in hold back end the other end be provided with T-shaped groove, in described T-shaped groove, be installed with T-shaped post, the bottom of described T-shaped post has helicitic texture, the opposite side of hole slot dams described in described limited post is positioned at, described limited post has internal thread through hole, the be threaded internal thread through hole of limited location post of the helicitic texture of described T-shaped post, the outside of described limited post is limited block, described limited block is installed in the positioning chamber of described die, the inner side end of described limited post and described in the dam other end of end leave gap.
It is further characterized in that: described die can be also template.
Adopt after structure of the present utility model, when producing excessive glue in the gap between shutoff valve and die, use bottle opener to go deep into internal thread through hole, rotate T-shaped post can make to dam end and die or template adhesion, and then take out the end of damming, and it makes to produce while overflowing glue in the gap between shutoff valve and die, and shutoff valve also can take out easily, guarantee the dismounting progress of mould, improve the production efficiency of mould.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises die 1, runner 2, the end 3 of damming, the end 3 of damming is positioned at a side of the hole slot 4 that dams of die 1, its one end evagination is in runner 2, the other end of holding back end 3 is provided with T-shaped groove 5, in T-shaped groove 5, be installed with T-shaped post 6, the bottom of T-shaped post 6 has helicitic texture 7, limited post 8 is positioned at the opposite side of the hole slot 4 that dams, limited post 8 has internal thread through hole 9, the helicitic texture screw thread 7 of T-shaped post 6 is connected with the internal thread through hole 9 of limited post 8, the outside of limited post 8 is limited block 10, limited block 10 is installed in the positioning chamber 11 of die 1, clearance D is left in the other end of the inner side end of limited post 8 and the end 3 of damming.Die 1 can be template.
