Description

Technical Field

[0001] The utility model belongs to the technical field of mold design, and particularly relates to a mold convenient for part demolding. Background Art

[0002] Most of the existing mass-produced automobile parts have complex curved surface structures, and usually require the processing of flanging and flanging hole processes. Most of the existing parts use vertical flanging around the circumference. After flanging, the parts are wrapped on the punch, resulting in the parts not being able to be demolded smoothly. The solution adopted in the prior art is to set a shedding frame on the mold to assist in demolding. However, there are some deficiencies in using the shedding frame. One is that a large space needs to be reserved for using the shedding frame. The other is that the shedding frame needs to be set close to the flanging of the part, which is difficult to ensure uniform force on the part plate surface and is prone to deformation. Therefore, a mold convenient for part demolding is improved and designed. Summary of the Utility Model

[0003] In view of the above deficiencies existing in the prior art, the utility model provides a mold convenient for part demolding to solve the problems in the above background art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A mold convenient for part demolding includes an upper mold assembly and a lower mold assembly. The lower mold assembly includes a lower mold base and a lower blank holder core connected in the lower mold base. The upper mold assembly includes an upper mold base and an upper blank holder core connected in the upper mold base. Among them, the lower blank holder core and the upper blank holder core are used for installing automobile parts; a plurality of elastic ejector blocks are arranged on the lower mold base near the part flanging, and a reserved groove corresponding to the ejector blocks is arranged on the upper mold base.

[0006] By adopting the above structural design, the mold convenient for part demolding includes an upper mold assembly and a lower mold assembly. The lower mold assembly includes a lower mold base and a lower blank holder core connected in the lower mold base. The upper mold assembly includes an upper mold base and an upper blank holder core connected in the upper mold base. Among them, the lower blank holder core and the upper blank holder core are used for installing automobile parts; a plurality of elastic ejector blocks are arranged on the lower mold base near the part flanging, and a reserved groove corresponding to the ejector blocks is arranged on the upper mold base. After the part is flanged, the ejector blocks use their own elastic release to loosen the part, and at the same time ensure uniform force on the part contact surface and improve the processing quality.

[0007] Furthermore, a flanging mechanism is arranged between the upper mold assembly and the lower mold assembly. The flanging mechanism includes a flanging insert, a limit insert and an ejector block arranged around the lower blank holder core, wherein the flanging insert and the limit insert are fixed on the lower mold base.

[0008] By adopting the above structural design, the flanging work can be carried out through the limit insert block of the flanging mechanism. However, in order to further improve the processing quality of the flanging process, when the upper die assembly moves relative to the lower die base, the upper pressure core and the limit insert block cooperate with each other to further constrain and fix the automotive part as a whole, so as to prevent displacement or vibration of the automotive part during processing, resulting in deformation during flanging and improving the quality of the flanging of the automotive part.

[0009] Furthermore, the top block is an elastic rubber block, and the top block is fixed on one side close to the flanging insert block.

[0010] Furthermore, it further includes a wear-resistant plate, the wear-resistant plate is fixedly arranged on the outer surface of the lower pressure core, and the lower die base is provided with a protrusion for mutually adapting with the wear-resistant plate, so that when the lower pressure core slides in the lower die base, the lower pressure core can mutually frictionally adapt with the protrusion.

[0011] Furthermore, a plurality of guide posts are arranged in the lower die base, and a plurality of through holes adapted to the guide posts are provided on the lower pressure core.

[0012] Furthermore, a bottom block is arranged at the bottom of the lower pressure core.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The mold for facilitating part demolding includes an upper die assembly and a lower die assembly. The lower die assembly includes a lower die base and a lower pressure core connected in the lower die base. The upper die assembly includes an upper die base and an upper pressure core connected in the upper die base, wherein the lower pressure core and the upper pressure core are used for installing automotive parts; a plurality of elastic top blocks are arranged on the lower die base near the part flanging, and a reserved groove corresponding to the top blocks is arranged on the upper die base. After the part is flanged, the part is jacked loose by the elastic release of the top blocks themselves, and at the same time, the force on the contact surface of the part is ensured to be uniform, improving the processing quality.

A reserved groove 21 corresponding to the top blocks 4 is arranged on the upper die base 2. After the part is flanged, the part is loosened by the elastic release of the top blocks 4 themselves, and at the same time, the force on the contact surface of the part is ensured to be uniform, improving the processing quality. The accuracy of automotive parts is improved, and the manual operation and manufacturing costs are greatly reduced, which is more conducive to improving production efficiency.
