Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cups, in particular to a split water swelling mould capable of rapid drainage. Background Art
[0002] The working principle of the water-expanding mold is that water is injected into the mold by a water-expanding machine, and the product is formed after pressurization. After the work is completed, the water inside the mold needs to be discharged in time. The production is a cycle mode. If the drainage speed is slow or the water is not completely drained, it will affect the size and shape of the next product, and affect the product quality and production efficiency.
[0003] At present, the drainage of general water-swelling molds can only be done by drilling holes on the side of the lower die head. The drainage speed is slow and not clean, which will affect the stability of the product's appearance and size. If it takes a long time to wait for drainage, it will affect production efficiency. If there are small iron filings in the mold that cannot be discharged with the water, defects such as pits will appear on the surface of the product. Therefore, improvements are needed.
