Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of automobile lamp mask die flexible push rod mechanism, as shown in Fig. 1-5c, comprise the fixed die insert 2 be arranged on by screw on solid plate 1, the moving die insert 4 on moving platen 3 is arranged on by screw, the mould pin 5 on moving platen 3 is arranged on by screw, upper ejector retainner plate 6 in mould pin 5 and lower ejector retainner plate 7 is arranged on successively by screw, automobile lamp mask accessory 8 is formed between fixed die insert 2 and moving die insert 4, described moving die insert 4 is provided with movable pushing block 9, the upper end of described movable pushing block 9 is connected with described automobile lamp mask accessory 8, the lower end of described movable pushing block 9 is connected with the upper end that bending angle controls push rod 11 by the first elastomeric element 10, preferably the first elastomeric element 10 is Elastip pins, the lower end that described bending angle controls push rod 11 is connected with the upper end of straight push rod 13 by the second elastomeric element 12, preferably the second elastomeric element 12 is Elastip pins, the lower end of described straight push rod 13 is fixed in succession by screw and described lower ejector retainner plate 7, described bending angle controls push rod 11 and is arranged in described moving die insert 4.
During application, as Fig. 1, shown in Fig. 2 and Fig. 3, when injection moulding completes after mould opens, under promoting under the effect of injection machine top rod, ejector retainner plate 7 and upper ejector retainner plate 6 move upward, because straight push rod 13 is fixedly connected with lower ejector retainner plate 7 by screw, and then straight push rod 13 promotes bending angle and controls push rod 11 and move upward, bending angle controls push rod 11 promotion activity pushing block 9 and moves upward, movable pushing block 9 propelling vehicle car light face shield accessory 8 moves upward, after bending angle control push rod 11 is released from moving die insert 4, just there is bending in it, now, bending angle control push rod 11 after bending just promotion activity pushing block 9 makes it move to wrap direction, and then movable pushing block 9 is loosened with product, therefore solve product easily to be clamped by jacking block, the industry difficult point be not easily removed.
Particularly, as shown in Fig. 3 to 5c, preferably, the lower surface of movable pushing block 9 has the first horizontal plane (not shown), the upper surface that bending angle controls push rod 11 has the second horizontal plane 14 and the first control inclined-plane 15 respectively, second horizontal plane 14 and the first control inclined-plane 15 intersect, the lower surface that bending angle controls push rod 11 has the 3rd horizontal plane 16, the upper surface of straight push rod 13 has the 4th horizontal plane 17 and the second control inclined-plane the 18, four horizontal plane 17 and the second control inclined-plane 18 respectively and intersects.
Therefore, bending angle controls to present two kinds of contact conditions between push rod 11 and movable pushing block 9, the first contact condition is when mold injection, and the second horizontal plane 14 that lower surface i.e. the first horizontal plane and the bending angle of movable pushing block 9 control in the upper surface of push rod 11 contacts; The second contact condition is when after mould die sinking during ejecting product, and lower surface i.e. the first horizontal plane and the bending angle of movable pushing block 9 control first in the upper surface of push rod 11 and control inclined-plane 15 and contact.Similarly, bending angle controls also to present two kinds of contact conditions between push rod 11 and straight push rod 13, the first contact condition is when mold injection, and lower surface i.e. the 3rd horizontal plane 16 that bending angle controls push rod 11 contacts with the 4th horizontal plane 17 in the upper surface of straight push rod 13; The second contact condition is when after mould die sinking during ejecting product, and lower surface i.e. the 3rd horizontal plane 16 that bending angle controls push rod 11 controls inclined-plane 18 with second in the upper surface of straight push rod 13 and contacts.Thus, when after mould die sinking, under the effect of injection machine top rod, lower ejector retainner plate promotes straight push rod successively, bending angle controls push rod, movable pushing block and automobile lamp mask accessory and moves upward, after bending angle control push rod is promoted out from moving die insert, just there is bending, bending angle after bending controls push rod promotion activity pushing block makes it move to wrap direction, and then movable pushing block and product are loosened, therefore solve product easily to be clamped by jacking block, the industry difficult point be not easily removed.
Preferably, first controls the angle between inclined-plane 15 and the second horizontal plane 14, and the second angle controlled between inclined-plane 18 and the 4th horizontal plane 17 can adjust.As long as according to the structure of different product, adjust the angle between the first control inclined-plane 15 and the second horizontal plane 14 respectively, and the angle that second controls between inclined-plane 18 and the 4th horizontal plane 17, car light face shield just can be avoided to greatest extent to be clamped by jacking block, thus solve this difficult problem of pickup difficulty in production process.
Provided by the invention a kind of that the automobile lamp mask die flexible push rod mechanism that jacking block is designed to movable pushing block is had design is ingenious, reliable in action, stable, and difficulty of processing is low, the advantage that cost is low.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
