[0031] Here’s how it works:

[0032] When the molding preparation of the helmet is to be carried out, the controller 3 provided on the right side of the top of the workbench 2 can be used to drive the first cylinder 5. In this way, the first cylinder 5 will push the opening and closing mold 6 provided on the left side to the left, so that the opening and closing mold 6 and the fixed mold 7 are combined and tightly attached to each other to realize the formation of the helmet molding mold. Then, the material can be placed inside the mold, and the second cylinder 10 provided on the front side of the upper end of the bracket 9 can be driven to push down the squeezing ball 11 connected to the bottom of the second cylinder 10. In this way, the squeezing ball 11 will move into the mold to extrude the material, and with the heating effect of the mold, the material can be hot-melted to make the material match the internal shape of the opening and closing mold 6 and the fixed mold 7 to realize the molding preparation of the helmet. After a period of cooling, the first cylinder 5 and the second cylinder 10 can be driven respectively to open the opening and closing mold 6 and move the squeezing ball 11 upward. As before, the molded mold can be taken out from the fixed mold 7 to complete the rapid molding preparation of the helmet.

[0033] In order to facilitate the disassembly and assembly of the opening and closing mold 6 and the fixed mold 7 to realize the molding and preparation of different helmets, a convenient disassembly and assembly device 13 is also provided on the side of the opening and closing mold 6 and the fixed mold 7. That is, when the installation of the opening and closing mold 6 or the fixed mold 7 is required, the two connecting strips 131 provided on the side can be used to pre-connect with the card grooves 133 provided on both sides of the connecting frame 132 to realize the positioning combination and make the opening and closing mold 6 or the fixed mold 7 fit closely with the connecting frame 132 accurately. After the positioning combination is completed, the screw 1351 provided inside the rotating transmission assembly 135 can be used to make the screw 1351 realize the transmission upward movement of the threaded sleeve 1352 connected to the bottom, and the threaded sleeve 1352 can be moved upward with the threaded sleeve 1352. When the screw rod 1351 is reversed, the moving bar 1353 can be moved downward, and the moving bar 1353 can move upward synchronously, and the transmission frames 1354 connected to the left and right sides of the moving bar 1353 can realize relative movement. In this way, the connecting frame 1355 fastened to the bottom of the transmission frames 1354 on both sides can cooperate with the guide rod 1356 plugged in horizontally at the bottom to realize the lateral movement of the moving frame 1361 inside the locking assembly 136, so as to achieve rapid positioning, plugging and locking. When the screw rod 1351 is reversed, the moving bar 1353 can be moved downward, so that the moving bar 1353 can realize the opposite push of the transmission frames 1354 on both sides and the connecting frame 1355, so as to achieve subsequent rapid unlocking.

[0034] When the movable frames 1361 arranged inside the locking components 136 on both sides move in opposite directions, the connecting arms 1362 connected to the middle parts will be pulled so that the connecting arms 1362 will swing accordingly, and the sliding frames 1364 connected to the upper ends of the connecting arms 1362 can be affected by the swinging action and move in the opposite direction to the movable frame 1361, and cooperate with the movable frame 1361 and the sliding frame 1364 on one side to rebound, so that the sliding frame 1364 can be quickly pushed outward, thereby, the locking rod 1366 fastened to the middle part of the outer side of the sliding frame 1364 will be quickly inserted into the circular hole opened in the middle part of the connecting strip 131 to realize quick plug-in locking, so as to quickly combine and plug-in lock the opening and closing mold 6 or the fixed mold 7, meet the convenience of mold disassembly and assembly, and do not require too many cumbersome steps, thereby achieving the advantages of quick disassembly and assembly of the opening and closing mold 6 or the fixed mold 7 and improving the convenience of use.

[0035] The utility model provides a molding device for producing helmets, which is provided with a convenient disassembly and assembly device 13, that is, it cooperates with a connecting strip 131 and a card slot 133 to realize pre-positioning and combination, and under the threaded transmission of a screw rod 1351 and a threaded sleeve 1352 arranged inside a transmission component 135, a moving strip 1353 arranged at the bottom is moved up or down, so that the moving strip 1353 transmits a transmission frame 1354 connected to the left and right sides, so that a locking component 136 can realize a fast adjustment and conversion of a locked or unlocked state, and a locking component 136 is provided, that is, when a moving frame 1361 arranged inside moves, it can cooperate with the swing of a connecting arm 1362 and the elastic force of a compression spring 1365 to quickly push out a sliding frame 1364, so that the sliding frame 1364 pushes out a locking rod 1366, and is positioned, plugged and locked with the connecting strip 131, so that the mold is quickly disassembled and assembled, thereby achieving the advantages of quick disassembly and assembly of an opening and closing mold 6 or a fixed mold 7 and improving the convenience of use.
