Embodiment 1
[0083] The invention provides a green sand casting mold required in the brake pad preparation process, which mainly includes a mold plate 1, a pouring system 2, a guide column 4, and a mold core 3: the mold plate 1 includes a positive pressure plate 11 and Counter pressure plate 12; gating system 2, including sprue cup 21, runner 22, ingate 23 and riser 24, furthermore, sprue cup 21 is designed as a square of 67x90x103mm, the reason why it is large up and down, narrow in the middle, This is because the molten iron enters more smoothly and will not splash back; the main body of the vertical runner 222 in the runner 22 is divided into three sections, the bottom of each section is provided with an ingate 23, and the top is provided with a constriction. The internal cross-sections are isosceles trapezoidal structures of 15x30x30mm, 12.5x25x25mm and 10x20x20mm respectively, and the ingate 23 is a rectangle with a cross-sectional area of 4x40mm;
[0084] The guide column 4, includ...
