Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
For head it off, use a kind of injection mold with the quick ejecting mechanism of secondary, the quick ejecting structure of a set of special secondary coordinates conventional thimble, the common ejecting product of oblique top, effectively reduces adhesion, make pickup and easily and not damage product, realize the automated production of injection moulding machine.
A kind of injection mold with the quick ejecting mechanism of secondary that the utility model provides, as shown in Figure 1, comprising:
In thimble fixed head 2 and Ejector Retainer Plate 3, be provided with at least two described ejecting mechanisms, described ejecting mechanism at least comprises pedestal 9, pin push rod 4, thimble 5, circular arc mold insert 6, one pin 7 wear pedestal 9 and with pedestal 9 inside grooves in circular arc mold insert 6, pin push rod 4 withstands first jiao of circular arc mold insert 6, second jiao of circular arc mold insert 6 is withstood thimble 9, Ejector Retainer Plate also comprises that one ejects post 1 for 2 times, when ejecting post 1 jack-up Ejector Retainer Plate 3, when pin push rod 4 is pressed down by moving platen bottom surface 5, drive thimble 9 to eject, the sheathed elastic component in bottom of thimble 8, clamping mechanism, described elastic component pressurized bounce-back.
Further, be provided with limited post 10 on thimble fixed head 2, limited post 10 withstands described moving platen bottom surface 5, and thimble 8 motions stop, and described elastic component starts rebound reset.
As shown in Figure 1, described elastic component is spring 11, for giving the afterburning bounce-back of thimble 8 when backhaul.Injection machine ejecting mechanism retraction, thimble fixed head 2, Ejector Retainer Plate 3 and all parts that are fixed in the above do drawback movement because back stitching spring 11 acts on simultaneously.In the time that departing from the bottom surface 5 of moving platen, pin push rod 4 because the spring 11 being enclosed within on thimble 8 acts on, make circular arc mold insert 6 rotate return around pin 7.
Pin push rod 4 downward motion strokes equal the top of pin push rod 4 and the difference in height of limited block 10.The top of pin push rod 4 is higher than the height of limited block 10, can press down the moving platen bottom surface 5 until limited block 10 is also conflicted being subject to after the stopping of moving platen bottom surface 5.
The bottom external diameter of pin push rod 4 is greater than shaft, and making the cylinder that external diameter is slightly large can cover when circular arc mold insert 6 moves.The bottom surface of pin push rod 4 is plane or concave surface further, and in order to keep good contact, the bottom surface of pin push rod 4 can be plane or concave surface, preferably plane.
The summit of thimble 8 evenly arranges the balanced surface that forms forming part.In not having jack-up, each thimble 8 and oblique top remain in the plane of a unified level, and in the time realizing secondary acceleration, the thimble 8 of this ejecting mechanism simultaneously projection, forming part jack-up, keeps balance, delivers to the height that manipulator can be caught away.
As shown in Figure 2, be plastic mould design and the mechanism principle of this product.
Injection machine completes after injection mo(u)lding, and ejecting mechanism comes into operation, and in the time of the ejecting post 1 and travel forward of the push rod contact mould of injection machine, thimble fixed head 2, Ejector Retainer Plate 3 and the part being fixed in the above move simultaneously.When ejecting after certain distance; Pin push rod 4 touches the bottom surface 5 of moving platen, pin push rod 4 is no longer moved forward, when ejecting post 1 and continuing to eject forward, pin push rod 4 is static and withstand circular arc mold insert 6, and it is rotated around pin 7, passes through lever principle, make thimble 8 ejecting fast than other herein, as seen from Figure 3, ejection stroke is a certain proportion of amplification according to lever principle, and this process is until move to limited post 10 and contact and stop with the bottom surface 5 of moving platen.
Injection moulding completes after a circulation and starts next circulation, the described ejecting mechanism retraction of injection machine, and thimble fixed head 2, Ejector Retainer Plate 3 and all parts of being fixed in the above do drawback movement because of back stitching spring action simultaneously.In the time that departing from the bottom surface 5 of moving platen, pin push rod 4 because the spring 11 being enclosed within on thimble 8 acts on, make circular arc mold insert 7 rotate return around pin 7.
In sum, the design that secondary accelerates ejecting mechanism coordinates conventional oblique top, thimble is realized Mobile phone plastic product automation Production design scheme, now because there are several Zhi Dingzhen of balance to accelerate by this lever principle, Double-ejection, make product depart from other oblique top and thimble, make manipulator pickup easy, thereby make to improve the production efficiency of injection mo(u)lding, stabilized product quality, the rate of reducing the number of rejects and seconds, reduce production costs, alleviate heavy manual labor, improve working conditions, the competitiveness of safety in production and enhancing enterprise becomes possibility, make pickup and easily and not damage product, realize the automated production of injection moulding machine.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
