Abstract

The utility model provides a reverse buckle structure of a floating insert forcedly-demoulding product. The reverse buckle structure has a simple structure and can cause an annular reverse buckle to conveniently complete demoulding, the cost of a mould is reduced, the mould reset is quick, and the production efficiency is high. The reverse buckle structure comprises a front mould, a rear mould, an A plate and a B plate, wherein a mold cavity is formed between the front mould and the rear mould, the product is arranged in the mold cavity, and the annular reverse buckle is arranged at the lower part of the product; a surface needle plate, a bottom needle plate and a bottom plate are sequentially arranged under the B plate, and a movable cavity is formed between the surface needle plate and the B plate; the bottom of a top needle is fixedly connected between the surface needle plate and the bottom needle plate, and the top of the top needle penetrates through the B plate and the rear mould and then is butted against the mold cavity. The reverse buckle structure is characterized by also comprising a floating insert, the upper end of the floating insert is inserted into the annular reverse buckle, and the lower part of the floating insert penetrates through the rear mould, the B plate, the movable cavity, the surface needle plate and the bottom needle plate and then is outward-convexly provided with a boss structure.

Description

A kind of floating mold insert is de-goods back-off structure by force
Technical field
The utility model relates to the technical field of structures of product mold, is 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 utility model provides a kind of floating mold insert de-goods back-off structure by force, and 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.
Floating mold insert is a de-goods back-off structure by force, and 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 the lower surface of described B plate, and leave spacing H between the upper surface of the thick guide pillar in described bottom and the lower surface of described B plate, the thin guide pillar in described top runs through described B plate, 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 utility model, 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 the lower surface of B plate, 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 the upper end on floating mold insert, 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 utility model.
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, B plate 4 is run through at the top of thimble 11, after rear mold 2, be mounted on die cavity 5, it also comprises floating mold insert 12, and the upper end of floating mold insert 12 is goed deep in annular back-off 6, and rear mold 2 is run through in the bottom of floating mold insert 12, 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, the upper surface of the thick guide pillar 15 in bottom under matched moulds state is positioned at the below of the lower surface of B plate 4, and between the upper surface of the thick guide pillar 15 in bottom and the lower surface of 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.
