Description
Technical field
The utility model relates to a kind of die casting, sand mold mould or other plastic mould product ejecting mechanism, especially casting sand type mold ejection mechanism.
Background technology
Existing die casting, sand mold mould or the multiplex back side of other plastic moulds presser type structure, this mechanism is relatively complicated, in work, often cause corresponding hole in plunger tip bar body and core box to interfere, only have the gap by increasing plunger tip bar body and the corresponding hole of core box to solve this problem, the shortcoming of this mode is, has increased the burr of the product model on plunger tip bar body side, has increased the time that workman clears up burr, affect production efficiency, waste resource.
Another shortcoming of aforesaid way is, this structure is higher to the accuracy of manufacture of part, and it is more difficult to process, and processing does not reach perfect precision likely will make bar and core box produce interference.
The shortcoming that also has of aforesaid way is that Assembly of the parts is relatively difficult, generally will lift from the back side and tighten screw.
The shortcoming that also has of aforesaid way is, the service life of part is relatively low, because part is dead on plunger tip plate, and may be because machining accuracy is inadequate or assemble the reason generation interference such as not in place, make part and core box produce wearing and tearing or distortion, thereby affect die life.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of accurate positioning, simple in structure, assembling is easy, there is the plunger tip linkage of certain activity adjustability and anti-rotation, to eliminate the current shortcoming that is adopted technology, the manufacture of this plunger tip linkage is simple, easy for installation, can effectively improve service life and shorten mould delivery date.There is individual T shape structure plunger tip bar body lower end, and the outside of plunger tip bar body lower end is the flat position of spline; A square plunger tip bar pressing plate, plunger tip bar pressing plate has T-slot and two screw holes, between the flat position of spline of plunger tip bar and plunger tip bar pressing plate, it is matched in clearance, by two screws, plunger tip bar pressing plate is locked on plunger tip plate, plunger tip bar is contained in T-slot and by flat position and prevents that plunger tip bar from rotating, and the length of plunger tip bar need to be set according to the actual grade of die cavity.
Technical solution of the present utility model is such, a kind of mould core box core ejection mechanism, comprise product model, plunger tip bar body, screw, core box, plunger tip bar pressing plate, plunger tip plate, it is characterized in that product model (1) is arranged on core box (4), there is plunger tip bar body (2) product model (1) bottom surface, plunger tip bar body (2) bottom is provided with plunger tip bar pressing plate (5), and by plunger tip bar pressing plate (5) and plunger tip bar body (2) being fixed in to plunger tip plate (6) end face with screw (3), plunger tip bar body (2) bottom bar head is T shape, its T shape is to there being ring pit between shaft, plunger tip bar pressing plate (5) has T-slot, the T shape bar head of plunger tip bar body (2) inserts the T-slot of plunger tip bar pressing plate (5), plunger tip plate (6) is to tightening up with screw (3) between plunger tip bar pressing plate (5).
Between the T-slot of the T shape structure of plunger tip bar body (2) and plunger tip bar pressing plate (5), it is matched in clearance.
Between product model (1) and plunger tip plate (6), be connected by plunger tip bar body (2).
Compared with prior art, the utility model has the advantage of: part handling ease, accurate positioning, simple and reasonable, assembling is simple, has certain flexibility, can prevent that plunger tip bar from rotating, and makes plunger tip bar participate in smoothly moulding.

Reference numeral: product model (1), plunger tip bar body (2), screw (3), core box (4), plunger tip bar pressing plate (5), plunger tip plate (6).
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the utility model.
Plunger tip linkage of the present utility model is by arranging a kind of floating type ejecting structure, can prevent that plunger tip bar and core box from too much interfering, and makes location more accurate by the flat position of spline, improved forming quality of products and mould and die accuracy.
Between the T-slot of the T shape structure of plunger tip bar body (2) and plunger tip bar pressing plate (5), it is matched in clearance.Between product model (1) and plunger tip plate (6), be connected by plunger tip bar body (2).
Embodiment 2, state when what Fig. 1 represented is the work of the utility model plunger tip linkage, when work, between the T shape lower end structure of plunger tip bar body (2) and plunger tip bar pressing plate (5), it is matched in clearance, can guarantee that plunger tip bar body (2) is except fluting horizontal direction position location, then by and core box (4) between coordinates and reaches the good result of locating completely.By screw (3), plunger tip bar pressing plate (5) is locked upper at plunger tip plate (6), prevents that plunger tip bar pressing plate (5) is mobile, and prevent that by flat position plunger tip bar from rotating, and makes it to participate in smoothly core moulding.Wherein plunger tip bar body (2) is after processing by turning with 45# steel, to do modified heat treatment to be made again. screw (3) adopts standard screws M8, plunger tip bar body (2) is enclosed within on the T-slot of plunger tip bar pressing plate (5), before having avoided, use screw thread directly to tighten at plunger tip plate (6) upper because of the dead stiff situation that makes plunger tip bar body (2) and core box (4) generation interference or collision wear and tear or fracture, tighten and fixedly make plunger tip bar pressing plate (5) drop and to move by screw (3), play the effect that guarantees positional precision. because plunger tip bar body (2) also will participate in the moulding of product model (1) sometimes, when special participation product model (1) curved surface forming, plunger tip bar body (2) upper end is need to be irregular, prevent that by flat position plunger tip bar body (2) from rotating, make plunger tip bar body (2) participate in smoothly moulding, improve the quality of core moulding.Compared with prior art, the utility model has the advantage of: requirement on machining accuracy is not high, accurate positioning; Assembling is simple; Simple and reasonable, there is certain adjustable flexibility; Can prevent that plunger tip bar from rotating, and makes plunger tip bar participate in smoothly moulding and improved the quality of core moulding.
Disclosed is above only a concrete example of implementing of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
