DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, an EVA insole mold that is easy to assemble or disassemble includes a fixed mold base 1. After removing multiple groups of fixing bolts 8, the pull bolt 6 is hooked with a hook lock or other tool, and the detachable mold 3 is removed from the inner side of the fixed mold base 1, so as to replace and overhaul the detachable mold 3. After the replacement or overhaul is completed, the EVA insole material is placed in the insole mold 4, and the cylinder 17 is started to push the push rod 18 to slide in the push rod sleeve 15, thereby pushing the pressing block 20 to slide downward, thereby pushing the pressing module 21 to slide downward, and the EVA insole material placed inside the insole mold 4 is compositely pressed.

[0023] Embodiment 2, as Figure 1-4As shown, an EVA insole mold that is easy to assemble or disassemble, the cylinder 17 pulls the push rod 18 again online, thereby pulling the pressing block 20 and the pressing module 21, so that the pressing module 21 is taken out from the inside of the insole mold 4, and air is blown into the air inlet 22. Since the multiple groups of air holes 5 are connected to the air inlet 22, the blown air will pass through the air holes 5 and blow into the space between the composite EVA insole and the insole mold 4, so that the EVA insole is cooled faster, allowing the staff to take out the insole more easily.

[0024] How it works

[0025] It should be noted that the utility model is an EVA insole mold that is easy to assemble or disassemble. When in use, after removing multiple sets of fixing bolts 8, use a hook lock or other tool to hook the pull bolt 6, and then remove the removable mold 3 from the inner side of the fixed mold seat 1, so as to replace and overhaul the removable mold 3. After the replacement or overhaul is completed, the EVA insole material is placed in the insole mold 4, and the cylinder 17 is started to push the push rod 18 to slide in the push rod sleeve 15, thereby pushing the pressing block 20 to slide downward, thereby pushing the pressing module 21 to slide downward. The EVA insole material placed inside the insole mold 4 is compositely pressed. After the composite pressing is completed, the cylinder 17 pulls the push rod 18 again, thereby pulling the pressing block 20 and the pressing module 21, so that the pressing module 21 is taken out from the inside of the insole mold 4, and air is blown into the air inlet 22. Since the multiple groups of air holes 5 are connected to the air inlet 22, the blown air will pass through the air holes 5 and blow into the space between the composite EVA insole and the insole mold 4, so that the EVA insole is cooled faster, so that the staff can take out the insole more easily.
