Description
Technical field
The utility model is related to a kind of automatically de- thread mechanism, more particularly to a kind of mold for having screw product
Automatically de- thread mechanism, mold can realize automatically de- thread.
Background technology
There is the plasthetics of helicitic texture, when doing mold design, traditional mold way is to be manually placed into edge with fixture
Part is molded to mold cavity and then takes out mold insert and product again, finally manually product is back-outed to come from mold insert.Such mold
In injection molding, production efficiency is low, quality of item can not ensure.
Utility model content
Problem to be solved in the utility model is to provide a kind of automatically de- thread mechanism, can realize automation Leave out thread.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of automatically de- thread mechanism, including being fixed on the sliding block on rear mold core top and being fixed on rear mold core lower part
First sub- shaft and the second sub- shaft are equipped with main shaft, first son between the first sub- shaft and the second sub- shaft
The top of shaft is equipped with first gear, and the top of the second sub- shaft is equipped with the 3rd gear, and the top of the 3rd gear is set
There is a rear mold pushing block, the top of the main shaft is equipped with second gear, and the lower part of the main shaft is equipped with the 4th gear, and described second
Gear engages cooperation with first gear and the 3rd gear respectively, and the left side of the first sub- shaft is equipped with rack, the rack
Left side is equipped with rack fixed block, and the left side of the rack fixed block is equipped with hydraulic cylinder, and the rack and the 4th gear coordinate.
During work, hydraulic cylinder band carry-over bar fixed block, rack fixed block band carry-over bar, rack drives the 4th gear turn
The dynamic, rotation of the 4th gear drives main shaft to rotate again, and main shaft, which rotates, drives second gear to rotate, second gear and the 3rd tooth
Wheel engagement drives rear mold core shaft to rotate again, when rear mold core shaft rotates, can move down, and turns so as to fulfill rear mold core
The thread of axis and product separates, and product is made to leave rear mold core shaft, at this moment injection molding machine can receive die sinking signal, utilize die sinking
Action opens sliding block.At this moment product is sticked on rear mold core, and the ejection of injection molding machine is recycled to act ejection rear mold pushing block
Separate product and rear mold core, so as to achieve the purpose that produce automatically.
The beneficial effects of the utility model：There is the mold of screw product to take off thread mechanism automatically, mold can realize it is complete from
Dynamic de- thread is removed from and manually takes product, reduces injection cycle, reduces injection cost, improves production efficiency.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 shows the structure diagram of the utility model.
Fig. 2 shows the structure diagram of product in Fig. 1.
Specific embodiment
The technical issues of in order to solve the utility model, use technical solution, obtain technique effect it can be readily appreciated that
With reference to specific attached drawing, specific embodiment of the present utility model is described further.As shown in Figs. 1-2, it is a kind of from
Dong Tuo threads mechanism, including the sliding block 1 for being fixed on 2 top of rear mold core and the first sub- shaft for being fixed on 2 lower part of rear mold core
10 and the second sub- shaft 6, main shaft 7, the first sub- shaft are equipped between the first sub- 10 and second sub- shaft 6 of shaft
10 top is equipped with first gear 12, and the top of the second sub- shaft 6 is equipped with the 3rd gear 5, the top of the 3rd gear 5
Equipped with rear mold pushing block 4, the top of the main shaft 7 is equipped with second gear 9, and the lower part of the main shaft 7 is equipped with the 4th gear 8,
The second gear 9 engages cooperation with 12 and the 3rd gear 5 of first gear respectively, and the left side of the first sub- shaft 10 is equipped with
Rack 11, the left side of the rack 11 are equipped with rack fixed block 13, and the left side of the rack fixed block 13 is equipped with hydraulic cylinder
14, the rack 11 coordinates with the 4th gear 8.
During work, hydraulic cylinder 14 is with carry-over bar fixed block 13, and for rack fixed block 13 with carry-over bar 11, rack 11 drives the
Four gears 8 rotate, the rotation of the 4th gear 8 drives main shaft 7 to rotate again, and main shaft 7, which rotates, drives second gear 9 to rotate, the
Two gears 9 are engaged with the 3rd gear 5 drives rear mold core shaft 6 to rotate again, when rear mold core shaft 6 rotates, past can move down
It is dynamic, it is separated so as to fulfill the thread of rear mold core shaft 6 and product 3, product 3 is made to leave rear mold core shaft 6, at this moment injection molding machine
Die sinking signal can be received, opens sliding block 1 using die sinking action.At this moment product 3 is sticked on rear mold core 2, is recycled
The ejection action ejection rear mold pushing block 4 of injection molding machine separates product 3 and rear mold core 2, so as to achieve the purpose that produce automatically.
The above is only the preferable specific embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, can be readily occurred in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
