Abstract
The invention discloses a pulling device of a fixed die top plate. The device comprises a top plate pull rod (1), a movable pin (2), a pull rod sleeve (3), and a moving die pull rod (4). In the invention, the device composed of the top plate pull rod, the movable pin, the pull rod sleeve, and the moving die pull rod is adopted for pulling the fixed die top plate for work. During application, the top plate pull rod, the movable pin, and the pull rod sleeve are arranged at a fixed die, and the moving die pull rod is disposed at a moving die. By means of the effects of die opening and the locking and loosing of the moving die rod in the rod sleeve by the movable pin of the top plate pull rod, the moving die pull rod pulls the top plate pull rod, which drives the fixed die top plate pushing an inclined push rod, so that an upside-down core block can tilt toward a core-pulling detachment product with the receding moving die synchronously. The technical scheme in the invention overcomes the problems and defects of complex mechanism, high cost and poor reliability existing in existing technologies. And the provided pulling device of a fixed die top plate makes the mechanism driving the fixed die top plate reach the purposes of simple structure, reliable work, and low cost.
Description
Technical field
The present invention relates to the inner device of a kind of injection mold, specifically be meant in the injection mold, be used to spur cover half top board pushing tow angle ejector rod, will be arranged in the pull unit of the back-off pellet of cover half die cavity from a kind of cover half top board of the back-off structure of goods oblique top extraction.
Background technology
The back-off of cover half die cavity tiltedly top is loosed core, and the cover half top board need be set come the pushing tow angle ejector rod, and the back-off pellet that will be arranged in the cover half die cavity is tiltedly extracted out on the top from the positive back-off structure of goods; And the mode of promotion cover half top board, prior art adopts such as hydraulic oil cylinder driving is set, and perhaps adopts the spring ejecting mechanism; Auxilliary mechanism's complicacy, high, the poor synchronization of cost of establishing of hydraulic oil cylinder driving; The spring ejecting mechanism utilizes the mould die sinking, and dynamic model, cover half somatotype, spring push cover half top board be along with the dynamic model of retreating, the synchronous push angle ejector rod, and angle ejector rod drives the oblique cover half die cavity that stretches out of back-off pellet and tiltedly takes out the disengaging goods; Though the spring ejecting mechanism is simple in structure, because spring is easy to fatigue failure, service life is short, and functional reliability is poor, and phenomenon can take place can not push up every now and then, causes pulling goods, and often safeguards that the replacing spring is time-consuming, and time cost is high; Therefore, prior art exists that mechanism is complicated, cost is high, the problems and shortcomings of poor reliability.
Summary of the invention
To the problems and shortcomings that above-mentioned prior art exists, the present invention adopts the device that is made up of top board pull bar, removable pin, drag link sleeve, dynamic model pull bar to be used to drive the work of cover half top board, during application; Top board pull bar, removable pin, drag link sleeve are arranged on the cover half place; The dynamic model pull bar is arranged on the dynamic model place, utilizes the mould die sinking, the effect that the removable pin of top board pull bar is locked in drag link sleeve, unclamped the dynamic model pull bar; By dynamic model pull bar pulling top board pull bar; The top board pull bar drives the cover half top board, and cover half top board pushing tow angle ejector rod makes the back-off pellet loose core along with the dynamic model of retreating is synchronously oblique and breaks away from the technical scheme of goods; A kind of pull unit of cover half top board is provided, is intended to make the mechanism that drives the cover half top board to reach simple in structure, reliable operation, purpose that cost is low.
The objective of the invention is to realize like this: a kind of pull unit of cover half top board, comprise top board pull bar, removable pin, drag link sleeve, dynamic model pull bar, wherein: described top board pull bar is the shaft-like steel components that the top is provided with the cylinder step of flange step; The bottom centre of top board pull bar upwards is provided with circular blind hole, is called the drawing hole; From bottom to top, on the hole wall at 2/3 place of said drawing hole hole depth, the through hole that is provided with the rectangle of two symmetries is called slide opening; The following hole wall of said slide opening is provided with one and is called limit sliding chutes along the diametric groove of top board pull bar, and an end of said limit sliding chutes communicates with the outer post jamb of top board pull bar, and the other end terminates in the slide opening and do not communicate with the inwall in drawing hole;
Described removable pin is in the cross section being the steel components of the fan-shaped bulk of one section ring of intercepting on the annulus of rectangle; Thickness between inside and outside two arcuate flanks of removable pin is greater than the wall thickness in the said drawing hole of top board pull bar, and gauge between the top and bottom of removable pin and the width dimensions between the left and right side cooperate with said slide opening is movable respectively; Be fixed with the columniform spacer pin of downward protrusion below the removable pin; The said limit sliding chutes of the slide opening of said spacer pin and top board pull bar is slidingly matched; Each seamed edge of removable pin is equipped with the transition chamfering;
Described drag link sleeve be the bottom be provided with the flange step, the cylinder step tubular steel member of open hollow up and down; The tube wall diameter of drag link sleeve and the outer cylinder of top board pull bar are slidingly matched,
The lower end of the tube wall of drag link sleeve is provided with the step bead of diameter greater than the tube wall diameter; Be provided with the transition conical surface between the tube wall of said step bead and drag link sleeve;
