Description

A stamping mold for automobile dust cover

technical field

The utility model relates to the field of stamping molds for automobiles, in particular to a stamping mold for dustproof covers of automobiles.

Background technique

Mold is the basic process equipment of industrial production, and mold industry is an important part of machinery industry and high-tech industry. The output value of the mold industry in developed countries such as Japan and the United States has already exceeded the output value of the machine tool industry. Since 1997, the output value of my country's mold industry has also exceeded the output value of the machine tool industry. At present, mold technology has become one of the important symbols to measure a country's product manufacturing level, and it is a very important equipment industry. The mold industry directly serves the high-tech industrialization, and the mold industry itself adopts a large number of high-tech, such as CAD/CAE/CAM, new technology, new materials, various advanced manufacturing technologies and equipment, etc. The mold industry has become a high-tech industry. part. The industrialization of high-tech is inseparable from molds. The high-precision, high-complexity, high-consistency, high-production-efficiency and low-energy-consumption materials of its production parts are incomparable to general mechanical processing, and are becoming more and more popular. The attention of various industrial sectors of the country. Foreign countries compare molds to "golden keys", "metal processing emperors" and "the driving force for entering a wealthy society". With the development of the economy and the deepening of the degree of opening to the outside world, my country's machinery industry has developed rapidly.

Stamping is the use of a die to apply pressure to a metal (or non-metal) sheet on a press.

It produces separation or plastic deformation to obtain parts with certain shape, size and performance

processing method. Stamping processing must have three elements, namely presses, dies and raw materials. Stamping is a kind of mechanical processing. Since it is usually carried out at room temperature, it can be called cold stamping.

And because it is mainly used to process sheet metal parts, it is sometimes called sheet metal stamping. Many utensils and equipment parts used by people in daily life are manufactured by stamping. For example, the automobile shield uses a piece of metal sheet, and uses a mold to press the sheet on a press to punch out a circular shape. The rough blank is then formed by punching and stretching.

As shown in Figure 1 of the prior art automobile dustproof cover, forming involves three processes of blanking, deep drawing and punching. These three processes can be combined in different ways to determine the stamping process. The stamping scheme of the prior art is: blanking first, then deep drawing, and then punching. Using single-process mold production requires two processes, thus requiring two sets of molds, resulting in high production costs and low production efficiency, making it difficult to meet the requirements of medium-volume production.

Utility model content

The purpose of the utility model is to provide a stamping die for automobile dust cover which can realize two processes with only one pair of molds and can also improve the precision and production efficiency of the automobile dust cover.

In order to achieve the above object, the utility model provides the following technical solutions:

A stamping mold for automobile dust cover, comprising an upper mold and a lower mold, the upper mold includes an upper mold bottom plate, an upper template, an upper mold concave-convex mold, a punching punch and a mounting plate, and the upper mold is installed under the upper mold bottom plate On the surface, the concave-convex die of the upper die is installed on the upper template, the punching punch is installed in the concave-convex die of the upper die through the mounting plate, and the lower die includes the bottom plate of the lower die, the concave-convex die of the lower die, the punching die, and the ejector rod. And the spring, the concave and convex mold of the lower mold is installed on the bottom plate of the lower mold, the corresponding punching punch of the punching die is installed on the concave and convex mold of the lower mold, and the ejector rod is installed in the concave and convex mold of the lower mold through the spring and can be used to eject the upper Die Concave and Convex Dies.

Further, the upper mold and the lower mold are connected through guide pillars and guide sleeves.

Further, the upper mold is also provided with a mold handle, and a push rod is arranged in the mold handle.

The beneficial effects of the utility model are:

When the utility model is working, the strip is first sent to the center of the mold, and then the upper mold moves downward along the guide column, and the concave and convex die of the upper mold contacts the strip, moves downward, and then punches it. After blanking, the material continues to move downwards, and the strip is bent and deep-drawn due to the action of the concave-convex part of the upper die. When drawing to a certain extent, the concave-convex mold of the upper mold is in full contact with the concave-convex mold of the lower mold. And because of the action of the spring, the concave and convex dies of the upper mold are lifted up and move upwards, and the punching punch continues to move downwards to punch it out. After punching is completed, the upper mold moves upwards, and the workpiece is ejected by the spring bolt. Thereby it is shown that the utility model only needs one mold to realize two processes, and improves the precision and production efficiency of the automobile dustproof cover.

Fig. 2 is a sectional view of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 2, a kind of stamping mold of automobile dust cover comprises upper mold and lower mold, and described upper mold comprises upper mold bottom plate 1, upper template 2, upper mold concave-convex mold 3, punching punch 4 and mounting plate 5. The upper template 2 is installed on the lower surface of the upper mold bottom plate 1, the upper mold concave and convex mold 3 is installed on the upper template 2, the punching punch 4 is installed in the upper mold concave and convex mold 3 through the mounting plate 5, the The lower die comprises a lower die base plate 6, a lower die concave-convex die 7, a punching die 8, a push rod 9 and a spring 10, and the lower die concave-convex die 7 is installed on the lower die base plate 6, and the punching die 8 corresponds to punching The hole punch 4 is installed on the lower die concave-convex die 7, and the ejector rod 9 passes through the spring 10 and is installed in the lower die concave-convex die 7 and can be used to eject the upper die concave-convex die 7.

Further, the upper mold and the lower mold are connected through guide pillars 11 and guide sleeves 12 .

Further, a mold handle 13 is also arranged on the upper mold, and a push rod 14 is arranged inside the mold handle 13 .

The working principle of the utility model is:

When the utility model is working, at first the bar is delivered to the mold center position, then the upper die moves downward along the guide post 11, contacts the bar through the upper mold concave and convex die 3, moves downward, and then punches it. Continue to move downward after blanking, and the strip is bent and deep-drawn due to the action of the concave-convex part of the upper die concave-convex die 3. When drawing to a certain extent, the concave-convex mold 3 of the upper mold is completely in contact with the concave-convex mold 7 of the lower mold. And because of the effect of spring 10, patrix concave-convex die 3 is jacked up and moves upwards, punching punch 4 continues to move downwards, with its blanking, after finishing stamping, patrix moves upwards, and workpiece is ejected by spring bolt. Thereby it is shown that the utility model only needs one mold to realize two processes, and improves the precision and production efficiency of the automobile dustproof cover.

The above description does not limit the technical scope of the present utility model. Any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
