Description

Technical Field

[0001] The invention belongs to the technical field of hardware mould supports, and more specifically, particularly relates to a foldable load-bearing column. Background Art

[0002] In the stamping hardware mold industry, especially some larger molds, during the storage and transportation of the molds, in order to ensure the stability and reliability of the upper and lower molds, a load-bearing column is generally set at each of the four corners inside the mold to achieve the purpose of stably supporting the upper mold and avoiding damage to internal parts due to uneven force.

[0003] When the existing similar load-bearing columns are in use, since the load-bearing columns are directly supported from the lower mold base to the upper mold base, when the height of the upper mold is relatively large, the load-bearing columns will be much higher than the lower mold base. In this way, when the upper mold and the lower mold need to be separated for mold maintenance or other reasons, the load-bearing columns set on the lower mold will appear very abrupt, especially for large molds, which need to lift the upper mold from the lower mold. During the lifting process, the abrupt load-bearing columns can easily collide with the parts inside the upper mold, causing damage to the mold. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a foldable load-bearing column to solve the problem that when the existing similar load-bearing columns are in use, since the load-bearing columns are directly supported from the lower mold base to the upper mold base, when the height of the upper mold is relatively large, the load-bearing columns will be much higher than the lower mold base. In this way, when the upper mold and the lower mold need to be separated for mold maintenance or other reasons, the load-bearing columns arranged on the lower mold will appear very abrupt, especially for large molds, which need to lift the upper mold from the lower mold. During the lifting process, the abrupt load-bearing columns can easily collide with the parts inside the upper mold, causing damage to the mold.
