Description

A kind of double-slider lifter demoulding mechanism
Technical field
The present invention relates to a kind of mould applications, more particularly to a kind of double-slider lifter demoulding mechanism.
Background technology
Have reeded moulding for side wall, it is general to be molded using the mould with side die sinking function, for example, existing The Chinese utility model for having Publication No. CN205202027U discloses《Angle Pin side core-pulling injection mold》, including cover half component With dynamic model component, the cover half component includes top clamping plate, and Angle Pin is provided with top clamping plate, and top clamping plate center is provided with and poured Muzzle;The dynamic model component includes support plate, and support plate side center is provided with core, and support plate opposite side is connected with by cushion block Bottom clamp plate, core are arranged with moving platen and cavity plate successively outside, and cavity plate is built-in with the side core sliding block that Angle Pin runs through, and move Template, which is provided with, is used for the guide runner that side core sliding block slides, and side core sliding block, which is provided with after side core slipper block loose core, keeps final The stopping means of position;The release component released for plastic is provided with the cavity of the cushion block.
However, the side wall of some mouldings is in addition to groove, the also lug boss with some outwardly convexs, and these are convex The outer end in the portion of rising in this case, if using traditional side die-sinking die, is molding than center section or inner big During, side core sliding block is displaced outwardly from die side, and side core sliding block will cause to damage to lug boss, so, cause Traditional side die-sinking die cannot be molded the moulding with said structure feature.
The content of the invention
The technical problem to be solved in the present invention is the present situation for prior art, there is provided a kind of double-slider oblique top ingot stripper Structure so that some specific mouldings, these mouldings can be molded by being provided with the mould of the double-slider lifter demoulding mechanism Side wall there is groove, and the lug boss formed with outwardly convex on having reeded side wall, among the outer end ratio of lug boss Part is inner big.
Technical scheme is used by the present invention solves above-mentioned technical problem:A kind of double-slider lifter demoulding mechanism, it is special Sign is:Slide including fixed and arranged, the outer slide being slideably positioned on slide, the interior cunning being slideably positioned in outer slide Formed with required for being molded on the madial wall of block, the slip cylinder for promoting outer slide to be slided on slide, outer slide and inner slide The die cavity portion of moulding outline, inclined step hole from inside to outside, the shape on outer wall up and down of inner slide are offered in outer slide The ramp that Cheng Youyu step holes are adapted, back-moving spring is provided between outer slide and inner slide, slides and sets on inner slide The Angle Pin vertical with the hole wall of the step hole of outer slide is equipped with, offers that an internal orifice big collar extension is small to be in tilted layout in inner slide Trapezoidal hole, a side core-pulling component is provided with inner slide, and the side core-pulling mechanism includes being fixedly installed on consolidating on inner slide outer wall Reservation, one group of pull bar being fixedly installed in fixed seat, the spring being sheathed on each pull bar, it is slideably positioned in trapezoidal hole One group of trapezoidal side core positioned opposite, formed with for injection molding part side wall outwardly convex on the trapezoidal side core opposite flank Lug boss forming cavity, along the glide direction of trapezoidal side core between the end of each pull bar and corresponding each trapezoidal side core Normal direction slide set.
As an improvement, the cunning that fixation bar portion and trapezoidal side core that the pull bar includes being fixed in fixed seat are slidably connected Lever portion, the sleeve part slided on bar portion is sheathed on, is easy to the installation of pull bar.
Improve again, the top of the Angle Pin is arranged with a stop collar, by setting stop collar, limits the motion of inner slide Stroke.
Improving again, the slide includes sliding floor, the slip side plate positioned at outer slide both sides positioned at outer slide bottom, Slide in the opposing sidewalls of side plate formed with step is oriented to, improve outer slide kinetic stability on slide.
Improve again, the limited post of restricted outer slide position is set on the sliding floor, limits the motion of outer slide Stroke.
Improve again, the output end for sliding cylinder, which is set, pulls block, on the outer slide in the side wall relative with sliding cylinder T-slot is offered, the pulling block is caught in T-slot, by setting pulling block block, is easy to slide the connection between cylinder and outer slide Set.
Compared with prior art, the advantage of the invention is that:For those specific mouldings, its side wall has groove, and The lug boss formed with outwardly convex on having reeded side wall, the outer end of lug boss is bigger than center section or the inner, Need to use the mould for being provided with the double-slider lifter demoulding mechanism to carry out injection molding, specifically, completed in mold injection Afterwards, while dynamic model molds, cylinder action is slided, outer slide slides on slide, and outer slide promotes inner slide to slide, outer slide Separated with the die cavity portion on inner slide from the side wall of moulding, simultaneously, with employing what is be in tilted layout in outer slide Step hole, during inner slide is with outer slide transverse shifting, inner slide moves up along inclined-plane, in interior slide block movement mistake Cheng Zhong, one group of trapezoidal side core in inner slide moves along trapezoidal hole to moulding direction, due to employing inclination in inner slide The trapezoidal hole of arrangement, the trapezoidal big collar extension of inn is small, trapezoidal side core to moulding jack up during, the end of each pull bar with it is right Slided between each trapezoidal side core answered along the glide direction normal direction of trapezoidal side core, two such trapezoidal side core positioned opposite Mutually open, the lug boss on moulding realizes die sinking, so as to solve in those side walls formed with lug boss and lug boss Outer end be more than center section or the inner moulding be not easy the technical problem molded.
