Description
Technical field
The utility model relates to casting field, particularly plunger tip bar assembly under one.
Background technology
Under traditional cold-box, plunger tip bar is an integrally formed straight-bar, and its underpart is screw thread, for lower plunger tip bar is tightened in lower plunger tip plate, as shown in Figure 1.This design Problems existing and deficiency as follows:
1) under, plunger tip bar entirety is fixed on lower plunger tip plate, the lower plunger tip rod aperture that lower plunger tip bar and lower core box occur during matched moulds is usually interfered and stuck and cannot matched moulds, this needs operator's at substantial time and efforts to go to check stuck particular location, cause very large labour intensity, and inefficiency;
2) usual, the speed that lower plunger tip gets rusty and weares and teares, needs often to change; Or owing to changing mould, need often to change lower plunger tip bar.During replacing, need plunger tip bar under entirety to change, cause the wasting of resources, production cost is high, and spillage of material is large.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content
The purpose of this utility model is to provide a kind of lower plunger tip bar assembly, thus under overcoming the monoblock type of prior art, plunger tip bar easily causes itself and lower plunger tip rod aperture stuck and cannot the defect of matched moulds.
Another object of the present utility model is to provide a kind of lower plunger tip bar assembly, thus the wasting of resources that under overcoming the monoblock type of prior art, plunger tip bar needs integral replacing to cause and manufacturing cost high.
For achieving the above object, the utility model provides a kind of lower plunger tip bar assembly, and lower plunger tip bar assembly comprises: lower plunger tip bar, lower plunger tip bar is provided with the groove of annular apart from its a distance, lower surface; Pressing plate, the middle part of the end face of pressing plate is provided with the U-lag extended along its width, and the degree of depth of U-lag is less than the thickness of pressing plate, and the middle part of the bottom surface of pressing plate is provided with the breach extended along its width, the axis of U-lag and the dead in line of breach, the width of U-lag is less than the width of breach; Pressing plate is removably fixed on lower plunger tip plate; Wherein, under installment state, the groove of lower plunger tip bar is contained in U-lag, and the lower end of same plunger tip bar is at present contained in breach.
Preferably, in technique scheme, lower plunger tip bar comprises: replacing portion, and the lower end in replacing portion is provided with external screw thread; General portion, one end of general portion is provided with internal thread, and general portion is removably connected by internal thread and replacing portion; The groove of the annular that general portion is provided with apart from end face a distance of the other end.
Compared with prior art, the utility model has following beneficial effect:
The utility model avoids the stuck phenomenon of the lower plunger tip rod aperture of lower plunger tip bar and lower core box by the matched in clearance of general portion and pressing plate, reduces labour intensity, improves operating efficiency; This assembly highly versatile, and change lower plunger tip bar by part, save material and cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figure 2, lower plunger tip bar and pressing plate 4 is comprised according to the lower plunger tip bar assembly of the utility model detailed description of the invention.Lower plunger tip bar is flexibly connected with pressing plate 4, and pressing plate 4 is fixed on lower plunger tip plate 3.
Lower plunger tip bar comprises replacing portion 1 and general portion 2.The lower end in replacing portion 1 is provided with external screw thread 11, and one end of general portion 2 is provided with internal thread 21, and general portion 2 is removably connected with replacing portion 1 by internal thread 21.Preferably, the external diameter of external screw thread 11 is less than the diameter in replacing portion 1, and the diameter of general portion 2 is identical with the diameter in replacing portion 1, is convenient to lower plunger tip bar successfully to insert in the lower plunger tip rod aperture of lower core box.General portion 2 is provided with the groove 22 of annular apart from end face a distance of the other end.
The middle part of the end face of pressing plate 4 is provided with the U-lag 41 extended along its width, the degree of depth of U-lag 41 is less than the thickness of pressing plate 4, the middle part of the bottom surface of pressing plate 4 is provided with the breach 42 extended along its width, the axis of U-lag 41 and the dead in line of breach 42, the width of U-lag 41 is less than the width of breach 42.Pressing plate 4 is arranged with two screwed holes 43.
During installation, be threaded connection and coupled together in replacing portion 1 and general portion 2, be contained in U-lag 41 by the groove 22 of general portion 2, the lower end of general portion 2 is contained in breach 42 simultaneously, then is fixed on lower plunger tip plate 3 by pressing plate 4 by screwed hole 43.Now, general portion and pressing plate form matched in clearance, and at dismounting mould, particularly during matched moulds, the lower plunger tip rod aperture of lower plunger tip bar and lower core box can activity adjustment, can avoid stuck phenomenon, reduce labour intensity, improve operating efficiency.
When needing to change lower plunger tip bar, replacing portion 1 can be removed from general portion 2 and replace, not need general portion 2 to disassemble from pressing plate; And general portion 2 also can be general with the replacing portion 1 of the lower plunger tip bar of other different sizes, highly versatile.Therefore, only need the replacing portion producing lower plunger tip bar as replacement object, save material, save cost.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
