Abstract
The utility model provides an upside-down forced demoulding structure which is simple in structure and capable of enabling an annular reversed buckle to be demoulded conveniently and reducing cost of a die; and the die is quick to restore, thus production efficiency is high. The upside-down forced demoulding structure comprises a front die, a back die, a plate A and a plate B, wherein the front die and the back die encircle to form a cavity; a product is arranged in the cavity; the annular reversed buckle is arranged at the lower part of the product; a surface needle plate, a bottom needle plate and a base plate are arranged under the plate B in sequence; a movable cavity is reserved between the surface needle plate and the plate B; the surface needle plate and the bottom needle plate are fixedly connected to the bottom of a thimble; and the top of the thimble penetrates through the plate B and the back die and supported in the cavity. The upside-down forced demoulding structure is characterized in that the upside-down forced demoulding structure also comprises a floating insert; the upper end of the floating insert stretches into the annular inversed buckle; the lower part of the floating insert penetrates through the back die, the plate B, the movable cavity, the surface needle plate and the bottom needle plate and then provided with a boss structure; and the boss structure is supported on a baffle.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is 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 utility model provides a kind of Enforced stripping structure of back-off, and it is simple in structure, makes annular back-off can 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 spacing hole that baffle plate forms, 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 location, the top closing in end of the aperture≤described stop collar of described transition shoulder, 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 mounts cover in the upper surface of the upper surface of described stop collar, described transition shoulder and the upper surface of described stop collar mutually concordant in upper surface and the described locating slot of described base plate.
Adopt after structure of the present utility model, 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 can complete easily the demoulding, reduced the cost of mould, and the reset of mould is fast, makes production efficiency high.
