Description

Injection mold T-slot formula oblique top side core-pulling mechanism
Technical field
The utility model relates to injection mold, particularly relates to injection mold T-slot formula oblique top side core-pulling mechanism.
Background technology
In injection mold, the inwall of working of plastics is shaped with hole clipping, the structures such as buckle, prior art normally adopts upper, lower ejector retainner plate arranges slide and thimble, slide arranges angle ejector rod, angle ejector rod bottom and slide are slidably matched, while working of plastics is ejected by thimble, angle ejector rod and slide are slidably matched the hole clipping or buckle of inwardly deviating from working of plastics, the shortcoming that this structure exists is: if the height of core is higher, and working of plastics eject distance, angle ejector rod will design longer, and angle ejector rod is long, after long-term work, easy wearing and tearing, fracture, angle ejector rod is short for service life.
Summary of the invention
The purpose of this utility model is the shortcoming existed to overcome prior art, provides a kind of and straight push rod and angle ejector rod is coordinated, shorten angle ejector rod length, ensure the injection mold T-slot formula oblique top side core-pulling mechanism in angle ejector rod service life.
The technical scheme of the utility model injection mold T-slot formula oblique top side core-pulling mechanism is: comprise compound plate and lower compound plate, locating piece and gate bush are set in upper compound plate, under upper compound plate, die cavity is set, perforation is had in lower compound plate, lower compound plate arranges mould pin, lower compound plate between mould pin is provided with ejector retainner plate and lower ejector retainner plate, on, between lower ejector retainner plate, thimble is set, the push rod of injector contacts with below lower ejector retainner plate through perforation, mould pin arranges backing plate, backing plate arranges core, the working of plastics of injection mo(u)lding is had between core and die cavity, working of plastics is shaped with inner panel, plate is shaped with interior hole clipping, it is characterized in that: in described core, have inclined guide groove, in inclined guide groove, angle ejector rod is set, T-slot is shaped with under angle ejector rod, upper, between lower ejector retainner plate, straight push rod is set, straight push rod is shaped with T-shaped slide block, the T-shaped slide block of thimble matches with the T-slot of angle ejector rod, projection is shaped with in angle ejector rod side, projection matches with the interior hole clipping of working of plastics.
The utility model discloses a kind of injection mold T-slot formula oblique top side core-pulling mechanism, principal character is that original longer oblique top is transformed into top is shorter angle ejector rod, bottom is the structure of straight push rod, T-slot is shaped with under angle ejector rod, straight push rod is shaped with T-shaped slide block and (also can be shaped with T-shaped slide block under angle ejector rod, T-slot is shaped with) under straight push rod, like this when after mould die sinking, withstood by injector push rod, lower ejector retainner plate maintains static, and lower compound plate band dynamic model pin, backing plate and core move backward, on, lower ejector retainner plate withstands straight push rod and thimble maintains static, straight push rod withstands angle ejector rod, because core moves backward, angle ejector rod coordinates with the inclined guide groove in core, angle ejector rod is made to deviate from hole clipping in working of plastics along the movement to the inside of the inclined guide groove in core, and the T-slot of angle ejector rod bottom coordinates with the T-shaped skid of straight push rod.This programme injection mold T-slot formula oblique top side core-pulling mechanism, the straight push rod of the angle ejector rod shorter by top and bottom coordinates through T-slot and T-shaped slide block, shortens the length of angle ejector rod, reduces the stressed of angle ejector rod and wearing and tearing, thus ensures its service life.
The utility model injection mold T-slot formula oblique top side core-pulling mechanism, described thimble is shaped with positioning ring groove.Make to form a locating ring below working of plastics, locating ring coordinates with positioning ring groove makes working of plastics be located, and avoids angle ejector rod to drive working of plastics to slide together when inner core pulling.
