Abstract
The invention relates to die-casting mould, in particular to a thimble structure for the die-casting mould. The die-casting mould consists of a fixed die and a moving die, wherein the moving die is provided with a thimble capable of extending to a die cavity to perform ejection movement. The thimble structure is characterized in that the one end, close to the die cavity of the moving die, of the thimble is provided with a barb-shaped skew notch. The thimble structure mainly solves the technical problem that parts can be taken out of the die cavity of the moving die very difficultly when the conventional die is used, and when the die-casting mould is opened, the parts can be taken out of the die cavity smoothly by using the thimble structure to achieve the aim of improving the product production efficiency.
Description
Technical field
The present invention relates to die casting, particularly a kind of thimble structure for die-casting mould.
Background technology
At present, extrusion process is widely used in industry, becomes the important means of production of the many parts in field such as automobile, electrical equipment instrument, characteristics such as shaping speed is fast, high efficiency, clean environment, smooth surface, forming part complicacy that it has.In production process; When part is got in die sinking, if the frictional force of cover half 1 relative part 4 greater than the frictional force of 2 pairs of parts of dynamic model, part 4 will be stayed cover half 1; Because cover half 1 does not have thimble; And thimble 3 often is arranged on dynamic model 2 one sides, causes being difficult to part 4 is taken out from the die cavity of mould cover half 1, thereby influences production efficiency.In existing mould design is that limit, the dark chamber of product is designed to dynamic model, and position, shallow chamber is designed to cover half, but still can not guarantee the generation of above-mentioned phenomenon, and is specifically as shown in Figure 1.
Summary of the invention
The object of the present invention is to provide a kind of thimble structure for die-casting mould; When using for solving existing mold; The very difficult technical problem that part is taken out from the die cavity of mould cover half; When the die casting die sinking, can from mold cavity, take out part smoothly, reach the purpose that improves production efficiency of products.
For realizing the foregoing invention purpose, technical scheme of the present invention is:
A kind of thimble structure for die-casting mould, this die casting is made up of fixed half and moving half, and described dynamic model is provided with the thimble that may extend into die cavity ejection activity; It is characterized in that: described thimble has the oblique breach of barb type near dynamic model die cavity one end.
Described thimble structure for die-casting mould is characterized in that: described thimble has a plurality of and laterally arranges, and the oblique breach of the barb type of thimble has equidirectional.
Compared with prior art, the invention has the beneficial effects as follows:
Use structure of the present invention will make the part stripping operation of die casting simple; And the thimble of processing in the structure of the present invention can both process with machine tool; Just also can reach requirement with the normal sands turbine at last; In Mold Making, do not have the increase of cost basically, and can improve diecast parts to stay cover half completely and the phenomenon that can not take out, thereby improved production efficiency.

The specific embodiment
See also Fig. 2-6, the invention provides a kind of thimble structure for die-casting mould.As shown in the figure: this die casting is made up of cover half 1 and dynamic model 2, and described dynamic model 2 is provided with the thimble 3 that may extend into die cavity ejection activity.As shown in Figure 2, described thimble 3 has the oblique breach 31 of barb type near dynamic model 2 die cavities one end.
As a kind of preferred implementation, described thimble 3 has a plurality of and laterally arranges, and the oblique breach 31 of the barb type of thimble has equidirectional.Certainly, if the direction of the oblique breach 31 of barb type difference slightly, maybe be in stripping operation result of use slightly poor, but also can implement.
Part stripping operation process of the present invention is following:
Like Fig. 3,, can rapidly the oblique breach 31 of the barb type of die cavity and thimble 3 be filled up aluminium liquid when getting into die cavity.
Like Fig. 4; When aluminium liquid solidifies die sinking afterwards; Product not only receives the frictional force of mould to it in dynamic model 2 sides, and receives the pulling force of the oblique breach of thimble barb type 31 places to it, and cover half 1 has only frictional force; So when dynamic model 2 separated with cover half 1, part 4 can rely on the oblique breach of barb type 31 places that its pulling force is stayed in dynamic model 2 die cavities.
Like Fig. 5, through ejection thimble 3 part 4 is deviate from dynamic model 2 die cavities again.
Like Fig. 6, part takes out, and taking-up power will be towards the opening direction (at this moment, will further embody the oblique breach 31 of barb type and have the superiority of equidirectional) of thimble, and taking-up knocks out the additional part of thimble again and separate afterwards on part.
In order not influence product appearance, can this thimble be arranged on runner and slag trap position.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
