The specific contents are as follows:

[0019] 1. When producing high boots, the mold is closed as a whole. When the whole is closed, the first card block is inserted into the first card slot, and the second card block is inserted into the second card slot to limit the whole. The middle plate can be positioned and has the function of separating the colors of the upper and lower layers. The molten rubber is added through the injection hole, and then the boots are formed. The middle frame is driven to move by starting the oil cylinder (the oil cylinder can also be set on the injection machine to drive the middle frame to move). When the middle frame moves, the guide rod slides in the sliding groove, and the T-shaped block is on the side. The shoe is slid in the positioning groove on the plate to limit the movement of the middle frame and improve the stability of the movement. After the middle frame moves, it drives the machine top rod and the upper inner core to move, so that the middle plate is separated from the bottom mold, and the lower inner core is separated from the upper inner core. The machine top rod, the upper inner core and the lower inner core are all equipped with a one-way blowing device to assist in demoulding and pulling out the sole, so that the boots can be removed.

[0020] 2. A fastening assembly is symmetrically arranged above the two shooting holes on the upper cover plate. The shooting holes are used to connect the pipes for shooting. After the pipes are connected to the shooting holes, the clamps can be fixed to the outside of the pipes. If the pipes are loose and are about to be separated from the shooting holes, the clamps can be driven to move. After the clamps move, the connecting rods can be driven to move through the connecting pieces. After the connecting rods move, the movable rods can be pushed to slide on the fixed blocks. While the movable rods move, the reset springs can be compressed through the connecting blocks, so that the arc sleeves on the movable rods can squeeze the shooting pipes to prevent the shooting pipes from falling off and affecting the use, thereby improving the practicality.
