Illustrate embodiment of the present utility model below by way of specific instantiation, those skilled in the art can be by this theory Content disclosed by bright book understands other advantages of the present utility model and effect easily.The utility model can also be by addition Different embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints with answering With, without departing from it is of the present utility model spirit under carry out various modifications or alterations.
Fig. 2, Fig. 3 and Fig. 4 are referred to, the utility model provides a kind of mould emptier, including a matrix 1, the front end of matrix 1 Provided with the domatic slideway 2 that one section of front end is low, rear end is high, the rear end of domatic slideway 2 is contour with the domatic rear end of slideway 2 provided with one section Plane slideway 3;It is additionally provided with matrix 1 on the slide rail 4 (see Fig. 3 and Fig. 6) parallel with domatic slideway 2, slide rail 4 and slidably connects one An axially slidable knock-pin 6 is connected with Loose core block 5, Loose core block 5, the upper end of knock-pin 6 is connected with an angled slide block 7, pushed up The lower end of rod 6 is against on the plane slideway 3 and domatic slideway 2 can be slided to along plane slideway 3.When stripping operation starts, The lower end of the knock-pin 6 is against the rear end of plane slideway 3, and the angled slide block 7 is fitted with workpiece 8 to be stripped;Workpiece 8 is opened Begin the demoulding while, nose motion of the Loose core block 5 along slide rail 4 to matrix 1, component velocity of the Loose core block 5 along stripping direction with Workpiece 8 is identical along the translational speed of stripping direction, and the lower end of knock-pin 6 is first slided along the rear end forward end of plane slideway 3, ejection Bar 6 gradually moves up and drives angled slide block 7 by workpiece 8 along upward jack-up vertically, makes axle of the workpiece 8 along tapping screw post 11 To the angled slide block 7 progressively disengaged on mould;Workpiece 8 is removed along stripping direction simultaneously;Slided when the lower end of knock-pin 6 is moved to plane During the front end in road 3, workpiece 8 is by jack-up to maximum height, and now, workpiece 8 is complete by the tapping screw post 11 on jack-up to workpiece 8 The state of angled slide block 7 on break away from moulds, so as to complete core_pulling demoulding.Thus, can using mould emptier of the present utility model Core_pulling demoulding operation is readily achieved, it is simple in construction, it is easy to operate.
In a kind of above-mentioned technical scheme of mould emptier of the present utility model, the slip of the slide rail 4 and Loose core block 5 connects The mode of connecing can realize by various ways, and Loose core block 5 is along the linear slide of slide rail 4, as a preferred mode, such as Fig. 3 and Fig. 6 Shown, the slide rail 4 is T-shaped, and the T-shaped chute that the Loose core block 5 is provided with T-shaped chute, Loose core block 5 is slided with T-shaped slide rail 4 Coordinate.The stroke that knock-pin 6 is moved along its axis should be more than the length of tapping screw post 11, to ensure the energy of tapping screw post 11 It is enough to be reliably separated with Loose core block 5.As a preferred mode, as shown in Fig. 2 the depanning of the plane slideway 3 and workpiece 8 Direction is parallel, and the bottom surface of Loose core block 5 is parallel with domatic slideway 2 and parallel with slide rail 4, when rear end of the Loose core block 5 along slide rail 4 is to cunning When the front end of rail 4 is slided, the rear end of the lower end edge plane slideway 3 of knock-pin 6 is slided to the front end of plane slideway 3, meanwhile, ejection Bar 6 moves axially upwards along it and drives angled slide block 7 by the jack-up of workpiece 8.As shown in Fig. 2 the direction slided of the Loose core block 5 with There is certain angle, the translational speed and slideway of the specific size of the angle according to workpiece 8 along depanning direction between domatic slideway 2 The translational speed of block and determine, velocity component of the translational speed of Loose core block 5 along the depanning direction of workpiece 8 and workpiece 8 are along depanning direction Translational speed it is equal.As shown in figure 5, in order to ensure that tapping screw post 11 on workpiece 8 can be successfully on break away from moulds Loose core block 5, the diameter parallel that the knock-pin 6 should be with the tapping screw post 11 on workpiece 8.
As a preferred mode, the lower end of the knock-pin 6 is provided with a slide head 9;Connect flexible on knock-pin 6 Element, one end of flexible member is against on slide head 9, and the other end is against around pilot hole lower end.Flexible member is by the bullet of slide head 9 Property be pressed on plane slideway 3 or domatic slideway 2, slide head 9 is kept close with plane slideway 3 or domatic slideway 2 Contact, slide head 9 can be connected with knock-pin 6 by the way of threaded connection, in order to dismantle.Preferably, the slide head 9 Diameter be more than the knock-pin 6 diameter, flexible member can elastic deformation, make slide head 9 keep with plane slideway 3 or The close contact of domatic slideway 2, the flexible member can be a compression spring 10 being socketed on knock-pin 6, compression spring 10 one end are against on slide head 9, and the other end, which is against around pilot hole lower end, to be located.Generally, compression spring 10 sets 3 millimeters With decrement.For the ease of being slidably matched for knock-pin 6 and Loose core block 5, it can be oriented in Loose core block 5 provided with one Hole, the knock-pin 6 is slidably matched with pilot hole, so, and guide rod can keep being axially moveable, and mobile steady.Such as Fig. 3 With shown in Fig. 6, limiting side wall 12 can be set in the both sides of the domatic slideway 2 and plane slideway 3, the slide head 9 is in Between two limiting side walls 12, it can prevent other parts from entering the motion of interference slide head 9 between two limiting side walls 12.
The utility model further relates to a kind of release method, using described in above-mentioned technical proposal and any preferred technical scheme Mould emptier carry out operation, comprise the following steps:
1) during original state, the lower end of the knock-pin 6 is against on the plane slideway 3, and the angled slide block 7 is stripped with waiting Workpiece 8 fit;
2) while workpiece 8 starts the demoulding, nose motion of the Loose core block 5 along 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 ejects angled slide block 7 along the axial direction of knock-pin 6 upward And tapping screw post 11 is departed 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 the rear end of knock-pin 6 from plane slideway 3 is moved to during the front end of plane slideway 3, knock-pin 6 along its 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 can be readily achieved using release method of the present utility model, It is simple in construction, it is easy to operate.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
