Description

Technical Field

[0001] The utility model belongs to the technical field of casting, and in particular relates to a casting coated sand mold pressing device. Background Art

[0002] In the foundry industry, the casting of coated sand generally requires the use of an upper and lower mold (or multiple molds) to combine and pour molten iron inside for casting.

[0003] CN206474646U discloses a casting coated sand mold clamping device, which uses a clamping structure to clamp the mold to form a machine-type clamping mechanism. The screw is controlled to clamp, which replaces the defects of the traditional clamping by the placeholder block. It can be adjusted according to the size of different molds and is suitable for mold clamping. However, after the die-casting, in order to ensure that the mold can be completely removed, the device generally needs to wait until the mold is cooled and fixed before opening, which requires a long waiting time, reducing work efficiency.
