The working principle of the invention is as follows:

the invention relates to a high-efficiency plastic mould capable of realizing rapid demoulding, which is characterized in that in the production and processing of the mould, the self guide adopts frustum guide and is matched with the surrounding limit, on the basis of not influencing normal blanking, a guide mode with smaller friction resistance is adopted, compared with cylindrical guide, in the movement process of mould closing, the friction resistance is in an increasing state, so that the friction consumption in the early stage is smaller, in addition, the frustum guide is adopted, the stress inclination of the surface of the frustum is directed to the center of an axis, the guide is more accurate, and the friction heating is less;

meanwhile, the inner demoulding structure adopts a pneumatic matching mechanical flexible thimble for demoulding, at the initial stage of mould closing, the push plate presses out the air in the outer frame 16, the air enters a gap between the inner wall of the upper mould and the outer wall of a finished product, the part loosely connected between the inner wall of the upper mould and the outer wall of the finished product is jacked away through pneumatic, at the moment, the damping sleeve and the damping rod mutually rub to synchronously move and push the plug downwards, when the resistance is too large, the damping rod and the damping sleeve mutually move, so that the acting force is always acted on the finished product in the air blowing process but not too large in a short period, the finished product can be gradually jacked open, at the end of the stroke of the damping rod and the damping sleeve, the connecting part between the finished product and the upper mould is jacked to be mostly opened, then the plug is pushed downwards through the damping sleeve to be finally pushed to be hard, at the connecting part between the finished product and the, the damage that causes that the action face atress is too big in avoiding the finished product short time better guarantees the finished product quality, and the thimble appearance adopts the frustum type, and portable and frame friction is little, removes in a flexible way, avoids causing the hindrance to air-blowing and flexible promotion stage, and after the compound die, through the extrusion of connecting rod and well cardboard lift, draw back the end cap inside the frame and crowd tightly at the lateral wall, avoid replying not in place, guarantee normal processing.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
