Abstract
The invention discloses a core ejection device for a sand core making machine and relates to casting machinery. The core ejection device comprises a pass box machine pressing plate (1) of the sand core making machine, a mandril plate (2) and a mandril (5), wherein the mandril plate (2) is arranged on the lower surface of the pass box machine pressing plate (1); a compaction screw sleeve (3) is sleeved outside a rod on the upper part of the mandril (5); the middle part of the compaction screw sleeve (3) is connected with a locking nut (4); an external thread at the upper end of the compaction screw sleeve (3) is meshed with an internal thread in a hole of the mandril plate (2). The core ejection device disclosed by the invention has the characteristics of shortening the maintenance period and improving the production efficiency along with simple and compact structure, convenience in manufacturing and assembling, safety, reliability and the like.
Description
Technical field
The present invention relates to foundry machinery, especially a kind of core ejecting device of manufacturing core machine.
Background technology
In casting industry, extensively adopt core machine processed to manufacture core, in core process processed, to make core need split away off from mould, because used casting model powder has certain viscosity, be difficult for making core to split away off from mould, by means of external force, core is departed from, existing mechanism structure used, core is withstood in the hole of inserting mould in push rod lower end, in the insertion mandrel plate bellmouth of reverse taper upper end, in mandrel plate upper surface, there is logical punch-out equipment pressing plate, utilize the power of core machine processed, logical punch-out equipment pressing plate moves down, force mandrel plate and push rod also to move down, the core that makes push rod lower end is break away from moulds also.In long-term use, push rod upper end coordinates with the hole of mandrel plate in mutual wearing and tearing, causes that gap is large between the two, occurs push rod dancing, easily makes push rod lower end hinder mould; If push rod lower end is inserted in the injured pit of mould, push rod fractures and hurts sb.'s feelings, and causes unsafe factor.
Summary of the invention
Object of the present invention is to provide a kind of simple in structure, adopts the core ejecting device of the upper end of push rod and the core machine processed of mandrel plate ruggedized construction.
Object of the present invention adopts technical scheme, the logical punch-out equipment pressing plate, mandrel plate, the push rod that comprise core machine processed, below described logical punch-out equipment pressing plate, there is mandrel plate, its push rod upper bar overcoat has gland nut, and gland nut middle part is connected with locking nut, upper external screw thread and push rod plate hole internal thread mesh.
Also have, gland nut lower end is six sides.
Further, the upper surface of the T-shaped head in the upper end of push rod and the distance of logical punch-out equipment pressing plate lower surface are greater than 0.5mm.
Further, lower anchor ring and the gland nut upper surface gapless of the T-shaped head in the upper end of push rod.
Further, interference fit between push rod top and gland nut.
The present invention is by means of having gland nut at push rod top overcoat, at gland nut, be connected with locking nut, push rod top is reinforced, at the power of core machine processed, logical punch-out equipment pressing plate is moved down, power passes to mandrel plate simultaneously, mandrel plate passes to locking nut again, pass to clamp nut and push rod push rod just moves down, push rod is stressed is like this evenly vertically to move down, and there will not be push rod dancing again.
The present invention, has simple and compact for structurely, makes easy to assemblyly, reduces maintenance period, has improved production efficiency, safety, the feature such as reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the present invention.
Fig. 1 is that the present invention uses state example structure schematic diagram.
In figure: 1-leads to punch-out equipment pressing plate 2-mandrel plate 3-gland nut 4-locking nut 5-push rod 6-mould.
The specific embodiment
See Fig. 1, the logical punch-out equipment pressing plate 1, mandrel plate 2, the push rod 5 that comprise core machine processed, described logical punch-out equipment pressing plate 1 has mandrel plate 2 below, and its push rod 5 upper bar overcoats have gland nut 3, and gland nut 3 middle parts are connected with locking nut 4, upper external screw thread and mandrel plate 2 hole internal threads mesh.
Also have, gland nut 3 lower ends are six sides.
Further, the upper surface of the T-shaped head in the upper end of push rod 5 and the distance of logical punch-out equipment pressing plate 1 lower surface are greater than 0.5mm.
Further, lower anchor ring and the gland nut 3 upper surface gaplesss of the T-shaped head in the upper end of push rod 5.
Further, interference fit between push rod 5 tops and gland nut 3.
Push rod 6 lower ends and mould 6 hole mated condition.Push rod 6 adopts commercially available Φ 16 standard push rods.
Claims (5)
