Description

A kind of saddle mould hold down gag

Technical field

The utility model belongs to saddle production technical field of auxiliary equipment, particularly relates to a kind of saddle mould hold down gag.

Background technology

Bicycle is one of modal vehicles, and easy control easy to learn, is loved by the people.Saddle is one of bicycle vitals; At present, the saddle on bicycle adopts foam process to produce usually, needs the saddle material of melting in injection machine to inject in mould in production engineering, the demoulding after it is shaping.The saddle material of melting is in foaming process, and volume increases; If do not take the necessary measures, expanded material jack-up mold will be caused, not only can cause saddle out-of-shape, saddle more can be caused off quality; Therefore in foaming process, need upper/lower die to compress.Traditional saddle forming production line does not have the mold pressing device of specialty, compaction process mechanization degree is low, and labour intensity is large, and production efficiency is low.

Summary of the invention

The utility model is for solving the problems of the technologies described above and providing a kind of saddle mould hold down gag.

Technical solution adopted in the utility model is: a kind of saddle mould hold down gag, comprise upper/lower die that one end is hinged, be connected to extend bottom bed die and to mold freedom end outside die holder, for clamping the fixture of upper/lower die and the mechanism for opening/closing for opening and closing fixture; Described fixture comprises the L shape bar that the column standing in described die holder extension, the sleeve be fixed on column, the compressor arm that can move up and down in sleeve and break are hinged on column top; Described L shape bar lower end and described compressor arm upper end are distinguished hinged by connecting rod; The lowering or hoisting gear that described mechanism for opening/closing comprises U-lag and U-lag can be made to rise and decline; Described U-lag notch towards described L shape bar direction, and surrounds described L shape bar free end; Described U-lag lifting can drive L shape bar to rotate and then drive compressor arm compress or unclamp mould.Before saddle foaming, mould and fixture move to mechanism for opening/closing place along with production line; By lowering or hoisting gear, U-lag is declined, U-lag upper wall pushes down L shape bar free end, drives L shape bar to rotate, and by connecting rod, and then drive compressor arm to decline, to connecting rod and compressor arm conllinear, fixture arrives dead-centre position, compresses upper/lower die; Along with fixture and mould leave mechanism for opening/closing scope, U-lag rises, and waits next group mould and fixture to arrive assigned address repeated work again; After having foamed, be in the fixture of clamped condition and mold movement to mechanism for opening/closing place, U-lag rises, and drives L shape bar to rotate, drives compressor arm to rise further, unclamp mould by connecting rod.

Fixture and mould are with production line motion, and mechanism for opening/closing is not with production line motion, and therefore L shape bar can move in U-lag; In order to reduce friction of motion, described L shape bar free end is provided with roller.

As preferably, the 0.5-1 of described U-lag width and described bed die width doubly.If U-lag is too narrow, then may causes also not complete opening and closing L shape bar and just have left U-lag, then cannot complete keying, especially compaction process; Enough spaces if U-lag is too wide, then production efficiency can be reduced, because must be had between two fixtures to be elevated for U-lag idle running.

As preferably, described lowering or hoisting gear is cylinder, and structure is simple, is easy to control.

As preferably, described cylinder is hung on beam or by support by suspension bracket and props up on bottom surface.

The advantage that the utility model has and good effect are: because the utility model adopts as above technical scheme, and mould, in the clamping of fixture dead-centre position, can not be opened because foaming and intumescing power is large; Fixture is clamped by mechanism for opening/closing and unclamps mould, and mechanization degree is high, does not need manual operation, and labour intensity is low, and production efficiency is high.

Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that the utility model can solve, technical scheme and these technical characteristics bring, will be described in further detail hereinafter by reference to the accompanying drawings.

Detailed description of the invention

For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

As depicted in figs. 1 and 2, the present embodiment is a kind of saddle mould hold down gag, comprise mold 10 bed die 11 that one end is hinged, be connected to extend bottom bed die 11 and to mold freedom end outside die holder 1, for clamping the fixture of upper/lower die and the mechanism for opening/closing for opening and closing fixture; Described fixture comprises the L shape bar 6 that the column 2 standing in described die holder 1 extension, the sleeve 4 be fixed on column 2, the compressor arm 3 that can move up and down in sleeve 4 and break are hinged on column top; It is hinged respectively that connecting rod 5 is passed through in described L shape bar 6 lower end and described compressor arm 3 upper end; Described L shape bar 6 free end is provided with roller 9; Described mechanism for opening/closing comprises cylinder 7 and U-lag 8; Described cylinder 7 is hung on beam by suspension bracket or props up on bottom surface by support; Described U-lag 8 sidewall is connected to the piston rod top of described cylinder 7; The 0.5-1 of described U-lag 8 width and described bed die 11 width doubly; Described U-lag 8 notch towards described L shape bar 6 direction, and surrounds described L shape bar 6 free end and roller 9; Described U-lag 8 lifting can drive L shape bar 6 to rotate and then drive compressor arm 3 compress or unclamp mould.

The course of work of the present utility model is: on saddle forming production line, often organizes on mould and is equipped with fixture; A mechanism for opening/closing is respectively established in latter two position before foaming; Before saddle foaming, mould and fixture move to mechanism for opening/closing place along with production line; By lowering or hoisting gear, U-lag is declined, U-lag upper wall pushes down the roller of L shape bar free end, drives L shape bar to rotate, and by connecting rod, and then drive compressor arm to decline, to connecting rod and compressor arm conllinear, fixture arrives dead-centre position, compresses upper/lower die; Along with fixture and mould leave mechanism for opening/closing scope, U-lag rises, and waits next group mould and fixture to arrive assigned address repeated work again; After having foamed, be in the fixture of clamped condition and mold movement to mechanism for opening/closing place, U-lag rises, and drives L shape bar to rotate, drives compressor arm to rise further, unclamp mould by connecting rod.

Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
