Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to a water-cooled explosion-proof intermediate mold for powder metallurgy. Background Technology

[0002] In traditional powder metallurgy designs, water-cooled intermediate molds typically have inlet and outlet ports at the bottom of the forming die to facilitate product cooling and improve product pressing stability. However, this design has a drawback: when the total product height exceeds 50mm, the water inlet and outlet pipes of the water-cooled intermediate mold are prone to bursting due to the large stroke of the forming die and the fact that the water pipes under the water-cooled intermediate mold must pass through gaskets. The water pipes are easily crushed by the gaskets as the forming die moves up and down. Utility Model Content

[0003] The purpose of this invention is to overcome the problems existing in the prior art and provide a powder metallurgy water-cooling intermediate mold to prevent water pipes from being crushed by the forming mold frame.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A water-cooled intermediate mold for powder metallurgy includes a water-cooled intermediate mold body. The water-cooled intermediate mold body is provided with a water-cooled circulation channel. The two ends of the water-cooled circulation channel are respectively provided with a water-cooled intermediate mold inlet and a water-cooled intermediate mold outlet. The water-cooled intermediate mold inlet and outlet are both located on the upper end face of the water-cooled intermediate mold body, so that the water-cooled intermediate mold inlet and outlet are connected to the corresponding water supply mechanism at the upper end of the water-cooled intermediate mold body through a water circulation pipeline.

[0005] Furthermore, the diameter of the water-cooled intermediate mold inlet and outlet is larger than the width of the corresponding powder feeder.

[0006] Furthermore, the water-cooled intermediate mold inlet and outlet are flared structures with a smaller bottom and a larger opening.

[0007] Furthermore, the water-cooling circulation channel is spirally arranged from top to bottom along the axial direction of the water-cooling intermediate mold body.

[0008] Furthermore, the outlet of the water-cooled intermediate mold is connected to the upper end of the water-cooling circulation channel, and the inlet of the water-cooled intermediate mold is connected to the lower end of the water-cooling circulation channel through an auxiliary water channel provided in the body of the water-cooled intermediate mold.

[0009] The beneficial effects of this utility model are: This invention places both the water inlet and outlet of the water-cooled intermediate mold on the water-cooled intermediate mold, preventing the water pipe from being crushed by the forming mold frame and improving the stability of powder metallurgy forming.
