Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a lost foam cutting device which is easy to fix. Background Art

[0002] Lost foam casting is a solid casting method that uses dry sand without binder and vacuum technology to make foam plastic molds. When making lost foam molds, workers conduct surveying and modeling based on the products provided by customers, and then design the lost foam molds. The foam is cut into specified sizes, and the molds are milled out on the foam. The foam molds are then transported to the foundry for casting. The molds after casting are processed by CNC milling machines and assembled by fitters.

[0003] In the prior art, the existing lost foam foam cutting device is not provided with a positioning device, and the foam cannot be fixed during the foam cutting process. Since the foam is light in weight, it is easy to be affected by external forces during the cutting process to cause movement or tilt, thereby affecting the cutting effect. In addition, irritating gases will be generated during the cutting process and directly discharged, which may affect the health of the workers. Utility Model Content
