Description

Technical Field

[0001] This utility model relates to the field of automotive mold processing technology, specifically to an automotive mold for precision machining. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). There are many types of stamping dies, and they are also classified according to three aspects: working nature, die structure, and die material.

[0003] In the stamping process, the top die and the bottom die that fixes the workpiece are the two most important components. They wear out after long-term use. Since the top die and the bottom die are usually fixed to the stamping equipment and the base plate, they are tightly connected and very inconvenient to disassemble. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a precision machining automobile mold with a simple structure, convenient use, and increased work efficiency due to the multi-station setting. At the same time, the top mold is not directly connected to the stamping equipment but is connected by a connecting plate. The bottom mold is also movably set in the mounting groove, making it convenient to replace the top mold and the bottom mold. It has a wide range of applications.

[0005] To solve the above-mentioned technical problems, this utility model provides a precision machining automotive mold, including a worktable, side support plates arranged around the worktable, a top plate arranged on the side support plates, a stamping device arranged on the top plate, a connecting plate arranged at the output end of the stamping device, and a top mold arranged at the bottom of the connecting plate; an installation groove is arranged on the worktable, a bottom mold is arranged inside the installation groove, and positioning devices are arranged on both sides of the bottom mold inside the installation groove.

[0006] Furthermore, a flange plate is provided at the bottom of the workbench, and a stamped upright plate is provided between the workbench and the flange plate.

[0007] Furthermore, the stamping equipment corresponds one-to-one with the bottom die, and at least two stamping equipment are provided.

[0008] Furthermore, the top plate is provided with a lifting ring on its upper surface and protective plates on both sides.

[0009] Furthermore, limit posts are provided on both sides of the mounting groove on the base plate.

[0010] Furthermore, the positioning device includes a positioning block, the bottom of which is provided with an auxiliary block adapted to the mounting groove, and the top of which is provided with a pressure plate adapted to the bottom mold. The pressure plate is fixed on the positioning block by a shaft.

[0011] Furthermore, reinforcing ribs are provided at the connection points between the side support plate and the top plate and the worktable.

[0012] Furthermore, an auxiliary support plate is also provided between the workbench and the top plate.

[0013] Furthermore, the bottom mold is provided with a guide shaft, and the fixed mold is provided with a through hole adapted to the guide shaft.

[0014] The beneficial effects of this utility model are as follows: When using this device, the bottom mold can be replaced as needed for the parts to be processed. The bottom mold can be removed by taking out the two clamping devices from the mounting groove. Then, the new bottom mold can be placed in the mounting groove and the above operation can be repeated to complete the replacement and fixing of the bottom mold. The top mold can also be removed from the connecting plate for replacement. It can be replaced according to the usage time without disassembling the stamping equipment. Therefore, it is convenient to replace the bottom mold and the top mold and has high efficiency. Attached Figure Description
