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 jacking mechanism that is used for automobile die.
Background technology
The Lifting Device that is applied to automobile die at present has two kinds usually, and one is a H type lifting jack, and there are defectives such as demand space is big, cost height 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 joint of cylinder the liftout push rod to be installed, and exist push rod easily to rotate, and product holds up defectives such as instability.
Summary of the invention
The objective 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 jacking mechanism of the automobile die of protection product surface quality.
Technical scheme of the present invention:
A kind of anti-rotation material jacking mechanism that is used for automobile die, comprise piston rod extension bar, pressing plate, cylinder joint, cylinder forward flange and cylinder, the piston rod extension bar is T type cylinder and is arranged in the lower mould body, the piston rod extension bar comprises the T type top of upper end, the extension bar at middle part and the groove of lower end, T type 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 the cylinder joint is by being threaded and cylinder is fixed, and the cylinder joint is inserted in the groove of piston rod extension bar; Pressing plate is fastened on the lower mould body by screw, and its vertical plane cooperates with anti-rotation planar slide on the piston rod extension bar.
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 jacking 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 guarantee that product does not influence surface quality because of unordered rotation by desirable movement locus motion.

Among the figure: 1. piston rod extension bar 2. pressing plates 3. cylinder joints 4. cylinder forward flanges 5. cylinders 6. lower mould bodies
The specific embodiment
Embodiment:
A kind of anti-rotation material jacking mechanism that is used for automobile die, comprise piston rod extension bar 1, pressing plate 2, cylinder joint 3, cylinder forward flange 4 and cylinder 5, piston rod extension bar 1 is T type cylinder and is arranged in the lower mould body 6, piston rod extension bar 1 comprises the T type top of upper end, the extension bar at middle part and the groove of lower end, T type 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 joint 3 is fixing with cylinder 5 by being threaded, and cylinder joint 3 is inserted in the groove of piston rod extension bar 1; Pressing plate 2 is fastened on the lower mould body 6 by screw, and its vertical plane cooperates with anti-rotation planar slide on the piston rod extension bar 1.
When cylinder 5 moves up and down normally, by with piston rod extension bar 1 in the rotation that comes limited piston bar extension bar 1 of the anti-rotation plane cunning pressing plate 2 of joining, thereby guaranteed that product does not rotate in the process that holds up, avoided product because hold up rotate and cause with defective such as mould collision cut.
