DETAILED DESCRIPTION
[0014] In order for those skilled in the art to better understand the technical scheme of the utility model, the specific embodiments thereof will be described in detail below with reference to the accompanying drawings.
[0015] As Figures 1-4 The detachable skateboard brick blank forming mold shown in the drawing, including female mold 1, sub-mold 6, sinking pouring groove is set up at the top of female mold 1, the shape of sub-mold 6 is matched with the pouring groove of female mold 1, and the guide column 2 is detachably arranged at the bottom of the pouring groove of female mold 1, the main mold plate 7, the limiting plate 8 and the molding column 9 with through holes are respectively set up in the sub-mold 6, the counterbore 10 is arranged at the top end of the through hole of the limiting plate 8, the through hole and the counterbore 10 are combined to form a convex shape structure, the convex flange 11 is arranged at the top of the molding column 9, and the convex flange 11 and the molding column 9 are combined to form a convex shape structure, the molding column 9 is coaxially arranged in the through hole of the limiting plate 8, the lower end of the molding column 9 penetrates the lower end of the limiting plate 8 downward, and the convex flange 11 is pressed in the counterbore 10, the main mold plate 7 is arranged at the top of the limiting plate 8, and the two are bolted and fixedly connected.
[0016] The through hole of the molding column 9 is arranged in a horn shape with a large lower end and a small upper end, and the hole diameter of the upper end of the through hole is smaller than the hole diameter of the through hole of the main mold plate 7.
[0017] The overall shape of the limiting plate 8 is matched with the main mold plate 7, the limiting boss 12 is arranged at the lower surface of the main mold plate 7 at both ends, and the section 13 is arranged at both ends of the limiting plate 8 corresponding to the limiting boss 12, when the two are connected, the section 13 of the limiting plate 8 is arranged on the inner side of the limiting boss 12 of the main mold plate 7, the limiting boss 12 is bolted and fixedly connected, and the stability of bolted connection is increased.
[0018] The height of the molding column 9 is consistent with the boss height of the skateboard brick.
[0019] The bottom of the casting groove of the mother mold 1 is provided with a positioning recessed hole 3 that matches the guide column 2.
[0020] The diameter of the through hole on the main template 7 is matched with the outer diameter of the guide column 2.
[0021] The lower end of the molding column 9 extends downwardly out of the lower end of the limiting plate 8 by 0.3 to 1 cm.
[0022] At least one exhaust microhole 4 is provided in the positioning recess 3 of the mother mold 1 , and an exhaust guide groove 5 is provided at the bottom of the guide pillar 2 corresponding to the exhaust microhole 4 .
[0023] Further, such as Figure 5 As shown, the mother mold 1 includes a plate body 14 and a casting mold frame 15. The casting mold frame 15 is detachably arranged on the top of the plate body 14 by bolts. The internal space of the casting mold frame 15 is the casting trough. When the casting mold frame 15 or the plate body 14 is worn, it can also be replaced without scrapping the entire body to save costs.
[0024] The working method of the present invention is as follows: when pressing the skateboard brick blank, first place the guide column 2 in the positioning recess 3 of the mother mold 1 for positioning, and connect the exhaust guide groove 5 with the exhaust micropore 4, then fill the clay into the casting groove of the mother mold 1, and finally place the modeling column 9 of the sub-mold 6 downward into the casting groove, and apply pressure to the top of the sub-mold 6 to press the skateboard brick blank. During the pressing process, the air squeezed out of the clay will enter the exhaust guide groove 5 from the gap between the guide column 2 and the positioning recess 3, and then be discharged from the exhaust micropore 4. When the modeling column 9 used to construct the shape is worn, first disassemble the main template 7 and the limit plate 8, replace the new modeling column 9, and then connect the main template 7 and the limit plate 8 as a whole for use. Similarly, when the limit plate 8 is worn, it can also be replaced in this way.
