Abstract

The invention provides a structure used for forcibly demoulding an inverted buckle at the lower part of a finished product and provided with a floating insert. The structure is simple, the ring-shaped inverted buckle can be demoulded conveniently, the cost of a mould is lowered, and the mould is reset quickly, so that the production efficiency is high. The structure comprises a front mould, a back mould, an A board and a B board, wherein a cavity is formed by the front mould and the back mould; the finished product is arranged in the cavity; the ring-shaped inverted buckle is arranged at the lower part of the finished product; a surface needle plate, a bottle needle plate and a bottom plate are sequentially arranged below the B board; a movable cavity is formed between the surface needle plate and the B board; the surface needle plate and the bottom needle plate are connected with the bottom of a thimble in a fastened manner; the top of the thimble penetrates the B board and the back mould and then is mounted in the cavity in an ejecting manner. The structure is characterized by further comprising the floating insert; the upper end of the floating insert stretches into the ring-shaped inverted buckle; the lower part of the floating insert penetrates the back mould, the B board, the movable cavity, the surface needle plate and the bottom needle plate and then is convex outwards to form a boss structure.

Description

A kind of floating mold insert is de-goods back-off structure by force

Technical field

The present invention relates to the technical field of structures of product mold, be specially a kind of floating mold insert de-goods back-off structure by force.

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 invention provides a kind of floating mold insert de-goods back-off structure by force, 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.

Take off by force a goods back-off structure, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, between rear mold, surrounding die cavity, is goods in described die cavity, and the bottom of described goods is with annular back-off, and 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, and rear mold is run through in the bottom of described floating mold insert, B plate, movable chamber, face needle plate, after end needle plate, evagination has boss structure, and the guide pillar of described floating mold insert is partly divided into the thin guide pillar in top, the thick guide pillar in bottom, the upper surface of the thick guide pillar in described bottom under matched moulds state is positioned at the below of described B Ban lower surface, and between the upper surface of the thick guide pillar in described bottom and described B Ban lower surface, leave spacing H, the thin guide pillar in described top runs through described B plate, and the aperture of the through hole in described B plate is less than the diameter of the thick guide pillar in bottom.

Adopt after structure of the present invention, front mould, rear mold completes after the demoulding, face needle plate, end needle plate is 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, owing to leaving spacing H between the upper surface of the thick guide pillar in bottom and B Ban lower surface, its distance that has limited the motion of floating mold insert is H, at this moment the back-off position on goods has departed from rear mold, goods continue to eject again, there has been the space of outside strain annular back-off position, just can depart from floating mold insert Shang upper end, goods have just been ejected smoothly, during matched moulds, by end needle plate boss structure, 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.

Accompanying drawing explanation

Fig. 1 is front view structural representation of the present invention.

The specific embodiment

See Fig. 1, it comprises front mould 1, rear mold 2, A plate 3, B plate 4,

front mould

1, 2 of rear molds surround die cavity 5, in die cavity 5, are goods, and the bottom of goods is with annular back-off 6, and the below successively of B plate 4 is provided with face needle plate 7, end needle plate 8, base plate 9, face needle plate 7, 4 of B plates leave movable chamber 10, face needle plate 7, 8 bottoms that are fastenedly connected thimble 11 of end needle plate, thimble 11 runs through B plate 4 in top, after rear mold 2, be mounted on die cavity 5, it also comprises floating mold insert 12, and floating mold insert 12 gos deep into upper end in annular back-off 6, and floating mold insert 12 runs through rear mold 2 in bottom, B plate 4, movable chamber 10, face needle plate 7, the rear evagination of end needle plate 8 has boss structure 13, and the guide pillar of floating mold insert 12 is partly divided into the thin guide pillar 14 in top, the thick guide pillar 15 in bottom, thick guide pillar 15 upper surface, matched moulds state Xia bottom is positioned at the below of the lower surface of B plate 4, and between the lower surface of thick guide pillar 15 upper surface, bottom and B plate 4, leave spacing H, the thin guide pillar 14 in top runs through B plate 4, and the aperture of the through hole in B plate 4 is less than the diameter of the thick guide pillar 15 in bottom.
