[0020] The utility model will be further described below in conjunction with the embodiments and drawings.
[0021] As Figure 1 and Figure 4 The vertical facade pull type slot die, comprising upper die 1 and lower die 2 arranged opposite, first core 3 is installed on the lower side of one end of upper die 1 and can move up and down, second core 6 is installed on the lower side of first core 3 and can turn outwards, upper die 1 is provided with first drive mechanism and second drive mechanism, first drive mechanism is used to drive first core 3 to move up and down, and second drive mechanism is used to drive second core 6 to turn inwards or outwards on the lower side of first core 3.
[0022] In the embodiment, the lower die 2 upper end has the concave model cavity 2a for forming product, and the upper die 1 lower end has the convex die 1b, when the die produces and manufactures the foam product 9, first, the first drive mechanism drives first core 3 to move up to the lower side of upper die 1 and be close, the second drive mechanism drives second core 6 to turn inwards to the lower side of first core 3 and be close, then upper die 1 is folded down on the lower die 2 upper end, at this moment, the convex die 1b, the concave model cavity 2a and first core 3 and second core 6 enclose the foaming cavity similar to the foam product 9, wherein the inside of the combined first core 3 and second core 6 is similar to the vertical facade style slot of the side wall of the foam product 9. Therefore, filling the foaming material into the die can form the foam product 9 with style slot 9a.
[0023] In the product forming process, after the up-and-down combination of first core 3 and second core 6, there is a micro gap between the two, which can play a role in exhausting during foaming, thereby avoiding defects in the vertical slot area of the product after foaming, and further improving the yield of the foam product 9 with style slot 9a. In addition, first core 3 and second core 6 are both movably installed, and through the combination of linear motion and rotation, it is more beneficial to the demolding of foam product 9.
[0024] Further, in combination with Figure 1 , Figure 2 and Figure 4 , the first core 3 is configured as an arc-shaped structure adapted to the cross section of the style slot 9a. The lower end of the second core 6 has an arc-shaped protrusion 6a, and after the inside of the first core 3 and the second core 6 is combined, the arc-shaped protrusion 6a can protrude inward beyond the first core 3. At this moment, the arc-shaped protrusion 6a can be used to form the style slot 9a, and the micro gap between the first core 3 and the second core 6 is beneficial to the ventilation of the foam during foaming.

In this way, the rotation of the second core 6 can be realized, the connecting rod 7 can increase the rotation angle of the second core 6 relative to the first core 3, and thus the demolding of the foam product 9 can be further facilitated.
[0027] In the embodiment, two groups of the second telescopic cylinder 5 are provided, the two groups of the second telescopic cylinder 5 are symmetrically installed at two end positions of the first core 3, and two ends of the second core 6 are respectively hinged to corresponding connecting rods 7.
