Abstract
The invention discloses an anti-rotation ejection mechanism for an automotive mold, which comprises a piston rod connecting rod, a pressure plate, a cylinder joint, a cylinder front flange and a cylinder, wherein the piston rod connecting rod is a T-shaped cylinder body and arranged in a lower mold body of the mold, the piston rod connecting rod comprises a T-shaped top at the upper end, a connecting rod in the middle part and a groove at the lower end, and the connecting rod is provided with an anti-rotation plane; the cylinder is fixed on the lower mold body of the mold by the cylinder front flange, the cylinder joint is fixed with the cylinder through threaded connection and sheathed in the groove of the piston rod connecting rod; and the pressure plate is fastened on the lower mold body of the mold by screws, and the vertical surface of the pressure plate is in sliding fit with the anti-rotation plane of the piston rod connecting rod. The anti-rotation ejection mechanism for the automotive mold has the advantages of simple and compact structure, and low manufacturing cost; as the main devices of the anti-rotation ejection mechanism are all arranged at the back of the lower mold, the mold becomes attractive and can conveniently and stably eject a manufacturing part, so that the manufacturing part can move along an ideal motion track so as to ensure that the manufacturing part can not influence the surface quality due to disordered rotation.
Description
Technical field
The present invention relates to the automobile die Lifting Device, particularly a kind of anti-rotation material lifting mechanism for automobile die.
Background technology
The Lifting Device that is applied at present automobile die has two kinds usually, and one is H type lifting jack, and there is large, the high in cost of production defective of demand space in the Lifting Device of this structure; It two is single cylinder top lifting device, and the characteristics of this structure Lifting Device are directly at the jiont treatment liftout push rod of cylinder, exist push rod easily to rotate, and product holds up the defectives such as unstable.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point; provide a kind of simple in structure, compact, cost is low; can conveniently be used for automobile die liftout field, guarantee that product does not rotate when holding up, the anti-rotation material lifting mechanism of the automobile die of protection product surface quality.
Technical scheme of the present invention:
A kind of anti-rotation material lifting mechanism for automobile die, comprise piston rod extension bar, pressing plate, cylinder connector, cylinder forward flange and cylinder, the piston rod extension bar is T-shaped cylinder and is arranged in the lower mould body, the piston rod extension bar comprises T-shaped top, the extension bar at middle part and the groove of lower end of upper end, T-shaped top profile is consistent with the product profile, the length of extension bar is highly identical with the jack-up of cylinder, and extension bar is provided with the anti-rotation plane; Cylinder is fixed on the lower mould body by the cylinder forward flange, and cylinder connector is threaded connection with cylinder and fixes, and cylinder connector is inserted in the groove of piston rod extension bar; On the lower mould body, its vertical plane cooperates with anti-rotation planar slide on the piston rod extension bar pressing plate by screw fastening.
Advantage of the present invention: compare with technology in the past that the present invention is simple in structure, compact, cost is low, because the main device of anti-rotation material lifting mechanism all is installed in the back side of counterdie, thereby make mould become attractive in appearance and can convenient, stable jack-up product, make product by desirable movement locus motion, guarantee that product does not affect surface quality because of unordered rotation.
Description of drawings
Fig. 1 is this anti-rotation material lifting mechanism sectional structure schematic diagram.
Fig. 2 is this anti-rotation material lifting mechanism perspective view.
Among the figure: 1. piston rod extension bar 2. pressing plates 3. cylinder connectors 4. cylinder forward flanges 5. cylinders 6. lower mould bodies
The specific embodiment
Embodiment:
A kind of anti-rotation material lifting mechanism for automobile die, comprise piston rod extension bar 1, pressing plate 2, cylinder connector 3, cylinder forward flange 4 and cylinder 5, piston rod extension bar 1 is T-shaped cylinder and is arranged in the lower mould body 6, piston rod extension bar 1 comprises T-shaped top, the extension bar at middle part and the groove of lower end of upper end, T-shaped top profile is consistent with the product profile, the length of extension bar is highly identical with the jack-up of cylinder 5, and extension bar is provided with the anti-rotation plane; Cylinder 5 is fixed on the lower mould body 6 by cylinder forward flange 4, and cylinder connector 3 is threaded connection with cylinder 5 fixing, and cylinder connector 3 is inserted in the groove of piston rod extension bar 1; On lower mould body 6, its vertical plane cooperates with anti-rotation planar slide on the piston rod extension bar 1 pressing plate 2 by screw fastening.
When cylinder 5 moves up and down normally, by with piston rod extension bar 1 in the anti-rotation plane cunning pressing plate 2 of joining come the rotation of limited piston bar extension bar 1, thereby guaranteed that product does not rotate in the process that holds up, avoided product because hold up rotate and cause with the defective such as mould collision cut
