Abstract
The invention provides a demolding mechanism and method. When demolding starts, the lower end of an ejection rod abuts against the rear end of a face slide way, and the ejection block is attached to a to-be-demolded workpiece; while the workpiece is demolded, a core-pulling block moves forwards the front end of a base block along a slide rail, the lower end of the ejection rod slides along the face slide way from the rear end of the face slide way to the front end of the face side way, the ejection rod gradually moves upwards in the axial direction to drive the ejection block so that the workpiece can be ejected upwards, and meanwhile the workpiece are moved out in the demolding direction; and when the lower end of the ejection rod moves to the front end of the face slide way, the workpiece is ejected to the maximum height, and at the moment, the workpiece is ejected to be in the state that a self-drilling screw column on the workpiece completely breaks away from the ejection block on a mold, so that core-pulling demolding is finished. Thus, through the demolding mechanism, core-pulling demolding operation can be convenient to finish, the structure is simple, and operation is convenient.

2) workpiece 8 start the demoulding while, the Loose core block 5 along nose motion from slide rail 4 to matrix 1, under knock-pin 6
The front end for sliding to plane slideway 3 along plane slideway 3 is held to slide, knock-pin 6 upward ejects angled slide block 7 along the axial direction of knock-pin 6
And make tapping screw post 11 depart from angled slide block 7.
In above-mentioned job step, the stroke that knock-pin 6 is moved along its axis should be more than the length of tapping screw post 11,
To ensure that tapping screw post 11 can be reliably separated with Loose core block 5.Such as, if tapping screw protrudes from the surface of workpiece 8
Length is L millimeters, then knock-pin 6 is moved to during the front end of plane slideway 3 from the rear end of plane slideway 3, and knock-pin 6 is along it
The stroke of axial movement is S millimeters, then S should be more than L, usually S >=L+2 millimeters.
Based on above-mentioned technical proposal, core_pulling demoulding operation, structure can be readily achieved using the release method of the present invention
Simply, it is easy to operate.
The principle and its effect of above-described embodiment only illustrative present invention, it is of the invention not for limiting.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and the scope without prejudice to the present invention to above-described embodiment.Cause
This, such as those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit
Into all equivalent modifications or change, should by the present invention claim be covered.
