Abstract
The invention provides an inverted-buckle forced demolding structure. By virtue of the simple structure, a circular inverted buckle can conveniently complete demolding, the cost of a mold is reduced, the mold is quick to reset, and the production efficiency is high. The forced demolding structure comprises a front mold, a rear mold, an A plate, and a B plate, wherein the front mold and the rear mold define a mold cavity; a manufactured product is arranged in the mold cavity; the circular inverted buckle is arranged at the lower part of the manufactured product; an ejector retainer plate, an ejector base plate and a bottom plate are arranged successively below the B plate; an activity cavity is defined between the ejector retainer plate and the B plate; the ejector retainer plate and the ejector base plate are securely connected to the bottom of an ejecting pin; the top of the ejecting pin passes through the B plate and the rear mold and is then installed in the mold cavity. The inverted-buckle forced demolding structure is characterized by also comprising a floating insert, wherein the upper end of the floating insert goes deep into the circular inverted buckle; the lower part of the floating insert passes through the rear mold, the B plate, the activity cavity, the ejector retainer plate and the ejector base plate and is provided with a boss structure which supports a baffle.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of Enforced stripping structure of back-off.
Background technology
There is an annular back-off below of goods, and existing structure need to be made complicated insert structure, just can complete the demoulding of this annular back-off, and it makes the cost of mould high, and mould reset efficiency is low, makes production efficiency low.
Summary of the invention
The Enforced stripping structure that the invention provides a kind of back-off, it is simple in structure, makes annular back-off to complete easily the demoulding, reduced the cost of mould, and the reset of mould is fast, makes production efficiency high.
A kind of Enforced stripping structure of back-off, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, between rear mold, surround die cavity, in described die cavity, be goods, the bottom of described goods is with annular back-off, the below successively of described B plate is provided with face needle plate, end needle plate, base plate, described needle plate, between B plate, leave movable chamber, described needle plate, between end needle plate, be fastenedly connected the bottom of thimble, described B plate is run through at the top of described thimble, after rear mold, be mounted on described die cavity, it is characterized in that: it also comprises floating mold insert, the upper end of described floating mold insert is goed deep in described annular back-off, rear mold is run through in the bottom of described floating mold insert, B plate, movable chamber, face needle plate, after end needle plate, be provided with boss structure, described boss structure is supported on baffle plate, described baffle plate is fastenedly connected described base plate, described stop collar is set in the boss structure of described floating mold insert, described stop collar is installed in described base plate, in the formed spacing hole of baffle plate, close up and leave spacing H between the lower surface of end and the upper surface of described boss structure in the location, top of the described stop collar under matched moulds state, the top of described boss structure is transition shoulder, the aperture of closing up and hold in the location, top of the aperture of described transition shoulder≤described stop collar, the aperture of the through hole of described floating mold insert in end needle plate described in the aperture > of described transition shoulder, needle plate of the described end under matched moulds state press-fits the upper surface in transition shoulder.
It is further characterized in that: the bottom of needle plate, the described end has locating slot, and the described stop collar evagination under matched moulds state is in the upper surface of described base plate and described locating slot mounts cover the upper surface of the upper surface in described stop collar, described transition shoulder and the upper surface of described stop collar is mutually concordant.
Adopt after structure of the present invention, front mould, rear mold complete after the demoulding, face needle plate, end needle plate are used rising at top roller, thimble rises, goods are ejected rear mold, owing to there being back-off on goods, goods eject drive floating mold insert together, the distance that has limited the boss structure motion of floating mold insert due to stop collar is H, at this moment the back-off position on goods has departed from rear mold, and goods continue to eject again, and there has been the space of outside strain annular back-off position, just can depart from the upper end on floating mold insert, goods have just been ejected smoothly.During matched moulds, by end needle plate, push down the transition shoulder on floating mold insert, floating mold insert is pushed back, it is simple in structure, makes annular back-off to complete easily the demoulding, reduced the cost of mould, and the reset of mould is fast, makes production efficiency high.
