Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically, to a beam cover plate stamping die with an ejection structure. Background Art

[0002] The crossbeam cover is an important part of the automobile crossbeam assembly. The crossbeam, crossbeam cover and crossbeam reinforcement plate together constitute the automobile crossbeam assembly. A cavity can be formed between the crossbeam cover and the crossbeam, thereby improving the supporting stiffness of the automobile crossbeam assembly.

[0003] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0004] Compared with ordinary metal parts, the crossbeam cover has a more complex structure, which makes it easier for the crossbeam cover to get stuck in the mold after stamping, making it more difficult to remove. Although some existing stamping dies have movable ejectors in the mold, the small range of movement of the ejectors is not enough to successfully remove the crossbeam cover. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a beam cover plate stamping die with an ejection structure which can apply pressure to the ejector from the bottom of the die so that the ejector is withdrawn from the inside of the die as a whole, thereby facilitating the removal of the beam cover plate.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A beam cover plate stamping die with an ejection structure comprises an upper die assembly, a lower die base assembly connected to the upper die assembly, and a lower die assembly arranged between the upper die assembly and the lower die base assembly, wherein a beam cover plate is arranged between the upper die assembly and the lower die base assembly; the upper die assembly comprises an upper die arranged in a rectangular structure, a connecting piece and a matching groove are arranged on the side of the upper die close to the lower die assembly, the lower die assembly comprises a lower die arranged in a rectangular structure, the shape and size of the lower die are matched with those of the upper die, and a plug-in groove is opened on the top of the lower die base assembly, and the lower die base assembly comprises a lower die base arranged in a rectangular structure, the shape and size of the lower die base are matched with those of the upper die.

[0008] The utility model is further configured as follows: the connecting piece and the matching groove are arranged along the width direction of the upper mold assembly and are symmetrically arranged about the axis line of the upper mold assembly; the connecting piece is installed on the side wall of the upper mold and is symmetrically arranged in two groups about the axis line in the length direction of the upper mold; the connecting piece is connected to the side wall of the lower mold base away from the upper mold; the matching groove is arranged as a rectangular structure and is arranged downward from the bottom of the upper mold, and the matching groove is inserted downward into the plug-in groove.

[0009] The utility model is further configured as follows: a group of engaging parts are arranged at the bottom of the upper mold close to the side of the lower mold, the engaging parts are arranged along the length direction of the upper mold, and their shapes are adapted to the shape of the crossbeam cover plate; an upper positioning bolt is arranged at the bottom of the upper mold, the upper positioning bolt is arranged as a cylindrical structure, and is symmetrically arranged in two rows about the axis of the engaging parts.

[0010] The utility model is further configured as follows: a mounting through hole is opened inside the lower mold along its length direction, an ejector is arranged inside the mounting through hole, the crossbeam cover is placed on the top of the ejector, the shape of the top of the ejector matches the shape of the crossbeam cover, and the shape and height of the plug-in groove are consistent with the matching groove.

[0011] The utility model is further configured as follows: two rows of lower positioning pins are arranged on the top of the lower mold along its length direction, the shape of the lower positioning pins is adapted to the shape of the upper positioning pins, and the positions correspond one-to-one with the upper positioning pins; a plurality of groups of bottom positioning pins are arranged on the bottom of the lower mold along the vertical direction, the bottom positioning pins are arranged as a cylindrical structure, and are arranged around the lower mold.

The positioning through holes are arranged to be circular structures with the same shape as the bottom positioning bolts, and the positions correspond one-to-one to the bottom positioning bolts.

[0013] By adopting the above technical solution, after the stamping process of the beam cover is completed, pressure can be directly applied to the ejector through the through hole on the lower die seat, so that the ejector is ejected from the inside of the mounting through hole on the lower die, making it easier to remove the beam cover.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:
