Abstract

The utility model discloses a door handle casting with convenient to processing. The door handle casting comprises a handle and a base, wherein one end of the handle is integrally cast and connected with the base, the interior of the base is cast with a base hole which penetrates through the base, the base hole penetrates through the surface of the handle, the other end of the handle is cast and connected with one end of a handle plug, the other end of the handle plug is of an arc surface structure, and the arc surface structure is matched with the handle surface through which the base hole penetrates. By adopting the technical scheme, the door handle casting with convenient to processing has the beneficial effects that the base hole in the base, the handle and the base are integrally cast, and the single grinding of the base hole is not needed, so the time and the labor are saved, the procedures are reduced, the production cost is reduced, and the working efficiency is improved; after a door handle is finally formed, the handle plug is cut off, and is arranged in an opening of the base hole penetrating through the base, so the attractive appearance is realized by the handle plug.

Description

A kind of door handle foundry goods of convenient processing

Technical field

The utility model belongs to field of mechanical technique, particularly relates to a kind of door handle foundry goods of convenient processing.

Background technology

As everyone knows, door handle is a kind of instrument generally using in our daily life, as long as there is door just to be unable to do without door handle, the door handle of moulding is generally all formed by door handle Mechanical processing of casting, existing technology is first by the integral body of door handle by die casting out, particularly the pedestal of door handle is all to cast solid post, then through puncher, get datum hole, in process, there are a lot of problems in such door handle foundry goods, first be the bad location of punching, the cylindric pedestal external diameter of handle is very little, during punching, easily penetrate base wall, if while selecting to polish from the external surface of door handle foundry goods pie handle, due to external surface smoother and there is radian, during punching, be easy to train off, inefficiency.Next is that operation is loaded down with trivial details, waste material, and the material of punching place has all been wasted.Again, even if having, pedestal is cast as hollow, also has the extra shutoff datum hole of external surface needs not attractive in appearance answer the reason of datum hole to make handle, increase difficulty of processing.

Utility model content

The utility model is to have the problems referred to above for existing technology, provides a kind of casting simple, the door handle foundry goods of convenient processing.

The problem existing for solving prior art, technical solution adopted in the utility model is:

A kind of door handle foundry goods of convenient processing, comprise handle and pedestal, one end of described handle is connected with the integrally casting of described pedestal, the cast inside of described pedestal has the datum hole that connects described pedestal, described datum hole runs through the surface of described handle, one end of the other end casting connection handle plug of described handle, the other end of described handle plug is globoidal structure, the handle surface that globoidal structure adaptation is run through by described datum hole.

Further improvement of the utility model is: described handle is the vertical pie with cambered surface, and described pedestal is cylindrical shape.

Further improvement of the utility model is: the other end of described pedestal is cast with column-like projection block.

Principle of the present utility model is: described handle is fixedly connected with pedestal, handle is set to the vertical pie with cambered surface, upper end is little, lower end is large, the radian of the palm of the hand when meeting people and holding, good hand touch, particularly the datum hole of base interior and handle and pedestal are together cast and are formed, do not need the datum hole of polishing separately, time saving and energy saving, reduce operation, reduce production costs, improved operating efficiency, the handle plug of described handle, at its lower end can cut down handle plug easily to embed in the datum hole mouth of base interior perforation pedestal after door handle final molding, not only blocked datum hole mouth, and seem better appearance in door handle profile.

The utility model is simple in structure, casts easy to processly, time saving and energy saving, and efficiency is high, cost-saving.

Fig. 2 is the rear elevation of the door handle foundry goods of a kind of convenient processing of the utility model.

Fig. 3 is the left view of the door handle foundry goods of a kind of convenient processing of the utility model.

Wherein: 1-handle, 2-pedestal, 3-handle plug, 4-datum hole, 5-projection.

The specific embodiment

Be below the utility model specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model conducted further description, but the utility model has more than and is limited to following examples.

As Figure 1-3, the utility model is a kind of door handle foundry goods of convenient processing, comprise handle and pedestal, one end of described handle 1 is connected with the integrally casting of pedestal 2, the cast inside of described pedestal 2 has the datum hole 4 that connects described pedestal 2, described datum hole 4 runs through the surface of handle 1, one end of the other end casting connection handle plug 3 of described handle 1, the other end of described handle plug 3 is globoidal structure, the handle surface that globoidal structure adaptation is run through by datum hole 4, described datum hole 4 is with described handle 1, pedestal 2 is cast and is formed together, described datum hole 4 quality of casting are better like this, can not locate bad and infringement part door handle foundry goods because of puncher, can need to not order a large amount of puncheres because operation is loaded down with trivial details yet, the door handle foundry goods of described this convenient processing uses manpower and material resources sparingly, improved production efficiency, described datum hole 4 extends to the surface of handle 1 by the center of projection 5, described projection 5 is when door handle is installed, to stretch into a position for body opposite side.

In the present embodiment, handle 1 is the vertical pie with cambered surface, upper end is little, lower end is large, and there is certain thickness, conveniently hold, the other end of handle 1 is cast with handle plug 3, handle plug 3 is also that same handle 1 is cast and formed together with pedestal 2, after the door handle of moulding is arranged on door, the opening of datum hole 4 one end can stick into Men Tili along with projection 5, door handle is fixed on door, the other end can leave opening, at this moment for the aesthetic of door handle integral body, can be when casting door handle foundry goods, the handle plug 3 conveniently cutting down in the casting of the lower end of handle 1, after door handle moulding, handle plug 3 can be cut down embed datum hole 4 away from that end opening of projection 5, final like this door handle seems will be more complete, attractive in appearance.
