in the figure: the device comprises a mounting seat 1, a guide block 2, a fixing block 3, a movable space 4, a die holder 5, a die 6, a sliding block 7, a through hole 8, a limit groove 9, a sliding rod 10, a movable block 11, a telescopic rod 12, an ejector block 13, a clamping block 14, a spring 15 and a pushing block 16.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 2, the spinning mechanism for aviation parts capable of rapidly demoulding comprises a mounting base 1, wherein two guide blocks 2 are fixed on one side of the mounting base 1; the fixing block 3 is arranged at one end, far away from the mounting seat 1, of the guide block 2; the mounting seat 1, the guide block 2 and the fixed block 3 together form a movable space 4, and the movable space 4 is used for limiting a pushing device of the mechanism; the die holder 5 is mounted on the fixed block 3 through bolts, and a die 6 is clamped on the die holder 5, so that the die 6, the fixed block 3 and the die holder 5 are fixed; a sliding block 7 is arranged in the movable space 4 and can move along the direction of the guide block 2, a through hole 8 is formed in the upper half part of the sliding block 7, and a longitudinal limiting groove 9 is formed in one side, close to the fixed block 3, of the through hole 8; the sliding rod 10 is further included, the rear end of the sliding rod 10 is fixed in the fixing block 3, and the front end of the sliding rod 10 penetrates through the through hole 8 in an inclined upward mode. Still include movable block 11, the movable block 11 cross-section is right trapezoid, cup joint in the slide bar 10 is outside, the bottom of movable block 11 is close to spacing groove 9, when slider 7 outwards promoted, can drive movable block 11 and slide along slide bar 10 together, carries out longitudinal sliding along spacing groove 9 simultaneously.
