Description

Forced resetting mechanism

Technical Field

The utility model relates to the technical field of mold, in particular to force canceling release mechanical system.

Background

In injection molding production, after a series of actions of mold opening and ejection are completed, an ejector plate ejected by a mold is often required to return to an initial position preferentially before the mold is closed due to the reasonability of a mold structure or the safety of the mold action.

In the existing mold manufacturing, the ejector pins possibly arranged in the design are arranged below the sliding block due to product reasons, the ejector pins can return when the sliding block is not matched with the mold in production due to spring reasons, but in actual production, the spring fails in long-time production, the ejector pins automatically rebound to the position without the action of the spring, and as a result, the sliding block is collided with the ejector pins, the ejector pins are broken by collision if the sliding block is light, and the sliding block is reworked if the sliding block is heavy.

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.

Referring to fig. 1, a forced resetting mechanism includes a bottom plate 11, a resetting mechanism disposed on the bottom plate 11;

the resetting mechanism comprises an upper template 7, a lower template part, a guide rod 1 and a resetting part;

the upper die plate 7 is arranged on the lower die portion, the upper end of the guide rod 1 is connected with the upper die plate 7, the resetting portion is arranged on the lower surface of the lower die portion, and the lower end of the guide rod 1 is inserted into the resetting portion and used for resetting.

The reset part comprises a limiting block 3, a floating plate 9, a swing rod 4, an ejector plate 6, a push plate 5 and a rotating unit;

ejector plate 6 sets up the upper surface at bottom plate 11, roof 12 is installed at the upper surface both ends of bottom plate 11, kickboard 9 sets up a pair of the upper surface of roof 12, stopper 3 is installed on kickboard 9, pendulum rod 4 sets up on kickboard 9 through the rotary unit, push pedal 5 sets up on ejector plate 6, the distal end setting of pendulum rod 4 is on push pedal 5.

The lower die part comprises a lower die plate 8 and a positioning block 2;

the positioning block 2 is arranged on the lower template 8.
