Specific embodiment
Embodiment 1
Please refer to Fig. 1-5, a kind of secondary structure de- by force of built-in mould, including moving template 2, ejection assembly and secondary group de- by force Part.
Wherein, the front end of moving template 2 is equipped with mavable module core 4, and mavable module core 4 is equipped with pushing block 5, dynamic model pin 6 and back-off pin 7;The rear end of moving template 2 is equipped with pin mounting groove 20.
Wherein, ejection assembly includes driving element and ejector retainner plate 3;Ejector retainner plate 3 is connect by push rod 9 with pushing block 5.
Wherein, secondary component de- by force is set in pin mounting groove 20 comprising buckle mold insert 10, movable insert 11, slide guide Mold insert 12, pin fixed block 14 and limited block 17.
Specifically, the one end for buckling mold insert 10 is connect with ejector retainner plate 3, and the other end is equipped with sliding slot 16;Sliding slot 16 is inlayed in buckle Opening is formed on the side of part 10, movable insert 11 slides in sliding slot 16.
Specifically, slide guide mold insert 12 is connected to moving template 2, which is provided with guide runner 13;Movable insert 11 is equipped with one and leads Slide-bar 15, slide guide axis 15 slide in guide runner.
Preferably, sliding stroke of the slide guide axis 15 in the glide direction for being parallel to movable insert 11 is greater than movable insert 11 protrude from the distance of buckle mold insert 10 in initial position.
Preferably, the upper end of pin fixed block 14 is connect with back-off pin 7, and lower end is equipped with the first fixture block 18;When described When movable insert protrudes from opening, movable insert 11 is resisted against on the first fixture block 18.
Preferably, buckle mold insert 10 is equipped with the second fixture block 19 far from one end of ejector retainner plate 3;When buckling the reset of mold insert 10, Second fixture block 19 is resisted against on the first fixture block 18, and pin fixed block 14 is driven to reset.
When buckling mold insert 10 from initial position forward movement, movable insert 11 protrudes from the opening, movable insert 11 It is resisted against the rear end of back-off pin 7 and back-off pin 7 is pushed to move forward;After buckling the forward movement certain distance of mold insert 10, Movable insert 11 is embedded in the opening, separately positioned with back-off pin 9, and the rear end for being buckled to pin 9 is resisted against pin installation The bottom of slot 20.
Specifically, the limited block 17 is set to the open end of pin mounting groove 20, for preventing pin fixed block 14 from institute It states and deviates from pin mounting groove 20.
Specifically, push rod 9 and buckle mold insert 10 are bolted and are fixed on ejector retainner plate 3.
The working principle of the secondary strong de- component of the present embodiment is as follows:
When die sinking, dynamic model is mutually disengaged with cover half, and ejector retainner plate 14 is ejected forward, and drives buckle mold insert 7 to travel forward, simultaneously Buckle mold insert 10 drives movable insert 11 to be ejected forward, and movable insert 11 acts against on pin fixed block 5, ejects pin fixed block 5;It is gradually mobile to the direction far from pin fixed plate 5 during movable insert 11 is ejected forward;When ejector retainner plate ejects 12mm Afterwards, movable insert 11 is fully retracted in guide runner 6, is detached from pin fixed block 5;Product is detached from rear mold pin 8 at this time.
When the secondary de- arrangement works by force of this built-in mould, the ejection and demoulding of injecting products are completed in two stages;First rank Section, when ejector retainner plate 3 starts to eject, and buckle mold insert 10 is moved forward from initial position, movable insert 11 protrudes from sliding slot 16 Opening, and back-off pin 7 is pushed to move forward;After buckling the forward movement certain distance of mold insert 10, product 1 is from dynamic model at this time Deviate from pin 6, movable insert 11 is embedded in opening, separately positioned with back-off pin 7;Second stage, ejector retainner plate 3 continue to push up Out, push rod 9 drives pushing block 5 to continue ejecting product, and the bottom that pin fixed block is resisted against pin mounting groove 20 at this time can not be forward Mobile, then product can be deformed to the position of former dynamic model pin, smoothly be deviate from.
The utility model is not limited to above embodiment, if the various changes or deformation to the utility model do not take off Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model Within the scope of, then the utility model is also intended to encompass these changes and deformation.
