Description
technical field [0001] The invention relates to the technical field of stamping dies, in particular to a hot knife cutting device for PU foamed products. Background technique [0002] With the improvement of people's living standards, automobiles have already become the main means of transportation in our daily life. People's requirements for the manufacturing process of automobiles and the quality of automobile products have also increased. PU foam products have been widely used in the automotive field. However, after the PU foam product is foamed and molded, flashes will appear on the molded parting surface. In the prior art, manual trimming is all used to remove burrs, which is inefficient and wastes labor; at the same time, the quality of PU foamed products cannot be guaranteed, thereby affecting the aesthetics and product quality of the product, and increasing the cost of the enterprise. Contents of the invention [0003] The purpose of the present invention is to so...
