Description

The straight top of injection mold oblique top combined type takes off back-off mechanism
Technical field
The present invention relates to injection mold, particularly relate to the straight top of injection mold oblique top combined type and take off back-off mechanism.
Background technology
Injection mold is after to the working of plastics injection mo(u)lding, when the inwall of working of plastics is shaped on back-off, when the demoulding, need together deviate from core by the back-off of oblique top and working of plastics, because oblique top is tilt slide, working of plastics is that straight line is deviate from, therefore oblique top and back-off groove are tilted to side slip when deviating from, and make the back-off of working of plastics make progress.Oblique top in the existing core all is by the oblique promotion of angle ejector rod, and the shortcoming that this structure exists is: angle ejector rod is subjected to lateral thrust power big owing to be to be obliquely installed when promoting oblique top, uses easy deformation, wearing and tearing for a long time, and service life is short.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists, provide a kind of and eject easily by the moving oblique top of straight pushing tow, directly push up stressed little, not yielding, wearing and tearing, guarantee that the straight top of the injection mold oblique top combined type in service life takes off back-off mechanism.
The technical scheme that the straight top of injection mold of the present invention oblique top combined type takes off back-off mechanism is: comprise die cavity and following compound plate, centring ring is installed on the die cavity, have perforation in the following compound plate, the mould pin is installed on the following compound plate, be provided with down ejector retainner plate and last ejector retainner plate between the mould pin, the injector push rod passes the perforation back and contacts below following ejector retainner plate, last, between the following ejector retainner plate push rod is set, on the mould pin gripper shoe is installed, mounting plate and core on the gripper shoe, fixed head is provided with stripper plate, and one of stripper plate and push rod is connected, at stripper plate, between core and the die cavity working of plastics is arranged, have oblique chute in the described core, tiltedly be provided with oblique top in the chute, be shaped on the back-off groove in the oblique top, the back-off groove matches with the back-off of working of plastics, it is characterized in that: on described, between the following ejector retainner plate straight top is set, is shaped on guide runner under the described oblique top, the guide runner inwall is shaped on sliding sliver, external wall of upper portion is shaped on chute on straight top, and chute matches with sliding sliver.
The invention discloses the straight top of a kind of injection mold oblique top combined type and take off back-off mechanism, when working of plastics in injection mold after the injection mo(u)lding, drive the mould pin by following compound plate, following ejector retainner plate, last ejector retainner plate, gripper shoe, fixed head, core and stripper plate are mobile backward, when moving to injector push rod position, the injector push rod passes perforation and withstands on down below the ejector retainner plate, following compound plate drives the mould pin, gripper shoe, fixed head and core continue mobile backward, and the injector push rod withstands down ejector retainner plate and last ejector retainner plate stops mobile, on, following ejector retainner plate drives push rod and Zhi Ding stops mobile, push rod withstands stripper plate, by stripper plate working of plastics is ejected from core, move up and directly withstand oblique top simultaneously, oblique top tilts to move up along the oblique chute of core, tilt to move up simultaneously in oblique top, the back-off of oblique top top and working of plastics is deviate from core, the slide guide bar of oblique top lower guide chute inwall cooperates with the chute on Zhi Ding top, it is smooth and easy to slide, not easy to wear, moving by straight pushing tow, eject easily, straight top is not subjected to lateral thrust power, and is not yielding, thereby guaranteed service life.
The straight top of injection mold of the present invention oblique top combined type takes off back-off mechanism, and described oblique top upper surface contacts with the working of plastics inwall.When deviating from, oblique top is positioned at the working of plastics center, plays booster action, makes the working of plastics demoulding more steady.
Description of drawings
Fig. 1 is that the straight top of injection mold oblique top combined type takes off back-off mechanism matched moulds status architecture schematic diagram;
Fig. 2 is that the straight top of injection mold oblique top combined type takes off back-off mechanism die opening state structural representation;
Fig. 3 is that the working of plastics that the straight top of injection mold oblique top combined type takes off back-off mechanism ejects the status architecture schematic diagram.
The specific embodiment
The present invention relates to the straight top of a kind of injection mold oblique top combined type and take off back-off mechanism, as Fig. 1-shown in Figure 3, comprise die cavity 1 and following compound plate 2, centring ring 3 is installed on the die cavity, have perforation 4 in the following compound plate, mould pin 5 is installed on the following compound plate, be provided with down ejector retainner plate 6 and last ejector retainner plate 7 between the mould pin, injector push rod 22 passes perforation 4 backs and contacts below following ejector retainner plate 6, last, between the following ejector retainner plate push rod 8 is set, gripper shoe 9 is installed on the mould pin, mounting plate 10 and core 11 on the gripper shoe, fixed head is provided with stripper plate 12, one of stripper plate and push rod is connected, at stripper plate 12, between core 11 and the die cavity 1 working of plastics 13 is arranged, have oblique chute 14 in the described core 11, tiltedly be provided with oblique top 15 in the chute, be shaped on back-off groove 16 in the oblique top, the back-off groove matches with the back-off 17 of working of plastics 13, it is characterized in that: on described, following ejector retainner plate 7, straight top 18 is set between 6, and described oblique top is shaped on guide runner 19 15 times, and the guide runner inwall is shaped on slide guide bar 20,18 external wall of upper portion are shaped on chute 21 on straight top, and chute 21 matches with slide guide bar 20.When working of plastics 13 in injection mold after the injection mo(u)lding, drive mould pin 5 by following compound plate 2, following ejector retainner plate 6, last ejector retainner plate 7, gripper shoe 9, fixed head 10, core 11 and stripper plate 12 are mobile backward, when moving to injector push rod 22 positions, injector push rod 22 passes perforation 4 and withstands on down below the ejector retainner plate 6, following compound plate 2 drives mould pin 5, gripper shoe 9, fixed head 10 and core 11 continue mobile backward, and injector push rod 22 withstands down ejector retainner plate 5 and last ejector retainner plate 6 stops mobile, on, following ejector retainner plate drives push rod 8 and straight top 18 stops mobile, push rod withstands stripper plate 12, by stripper plate working of plastics 13 is ejected from core 11, and simultaneously straight top 18 is withstood oblique top 15 and is moved up, oblique top tilts to move up along the oblique chute 14 of core, tilt to move up simultaneously in oblique top, the back-off of oblique top top and working of plastics is deviate from core, the slide guide bar 20 of oblique top 15 lower guide chutes 19 inwalls cooperates with the chute 21 on 18 tops, straight top, it is smooth and easy to slide, not easy to wear, moving by straight pushing tow, eject easily, straight top is not subjected to lateral thrust power, not yielding, thus service life guaranteed.Described oblique top 15 upper surfaces contact with working of plastics 13 inwalls.When deviating from, oblique top 15 is positioned at working of plastics 13 centers, plays booster action, makes the working of plastics demoulding more steady.
