The sealing mechanism 3 seals the upper mold base 7 and the lower mold base 2.

[0025] Please refer to it again. Figures 1-3 To facilitate sealing of the upper mold base 7 and the lower mold base 2, the sealing mechanism 3 in this embodiment includes a cavity 301 opened inside the lower mold base 2. Two vertical plates 302 are fixed between the upper and lower sides of the cavity 301. A first motor 303 is fixed to the right side of the left vertical plate 302. A first rotating rod 304 is fixed to the output shaft of the first motor 303. A transmission assembly 305 is provided on the outer surface of the first rotating rod 304. Two first lead screws 306 are rotatably connected between the left and right sides of the cavity 301 through bearing seats. The first rotating rod 304 drives the two first lead screws 306 to rotate simultaneously through the transmission assembly 305.

[0026] Two first lead screws 306 are threadedly connected to two moving blocks 307 on their outer surfaces. Rotation of the first lead screws 306 drives the two moving blocks 307 to move simultaneously relative to each other or simultaneously away from each other. Two fixed rods 308 are fixed on the opposite side of each of the two moving blocks 307. A connecting plate 309 is fixed on the opposite side of each of the two sets of fixed rods 308. Multiple locking rods 310 are fixed on the opposite side of each of the two connecting plates 309. The moving blocks 307 drive the connecting plates 309 and locking rods 310 to move together through the fixed rods 308. The sealing mechanism 3 also includes a sealing groove 312 opened on the upper surface of the lower mold base 2 and a sealing block 313 fixed on the lower surface of the upper mold base 7. The sealing mechanism 3 also includes multiple locking slots 311 opened on the left and right sides of the upper mold base 7. The sealing groove 312 and the sealing block 313 are both U-shaped. The sealing block 313 is inserted into the interior of the sealing groove 312 to seal the upper mold base 7 and the lower mold base 2.

[0027] The transmission assembly 305 comprises two first sprockets fixed to the outer surface of the first rotating rod 304 and a second sprocket fixed to the outer surface of the first screw rod 306. The outer surfaces of the left end first sprocket and the front end second sprocket are drivingly connected with a first chain, and the outer surfaces of the right end first sprocket and the rear end second sprocket are drivingly connected with a second chain. The first rotating rod 304 drives the two first screw rods 306 to rotate simultaneously through the transmission assembly 305.

[0028] In addition, the first screw rod 306 has two threads with opposite directions. The rotation of the first screw rod 306 drives the two moving blocks 307 to move in the same direction or in opposite directions simultaneously. The right side of the first rotating rod 304 is rotatably connected to the left side of the right end vertical plate 302 through a bearing seat, thereby increasing the stability of the first rotating rod 304 during rotation.

[0029] Furthermore, the left and right sides of the lower die seat 2 are provided with two slide holes, and the fixed rods 308 are slidingly connected in the slide holes. The moving blocks 307 drive the connecting plates 309 and the clamping rods 310 to move together through the fixed rods 308. The front and rear sides of the moving blocks 307 are fixed with sliding blocks, and the inner cavity of the cavity 301 is provided with two slide grooves on the front and rear sides. The sliding blocks are slidingly connected in the slide grooves, thereby increasing the stability of the moving blocks 307 during movement.

[0030] The sealing mechanism 3 in the embodiment is used to seal the upper die seat 7 and the lower die seat 2. The sealing block 313 is located in the sealing groove 312. The first motor 303 drives the first rotating rod 304 to rotate, and the first rotating rod 304 drives the two first screw rods 306 to rotate together through the transmission assembly 305. The two moving blocks 307 move in opposite directions simultaneously through the first screw rods 306. The moving blocks 307 drive the connecting plates 309 and the clamping rods 310 to move together through the fixed rods 308. The clamping rods 310 are clamped into the clamping grooves 311, thereby sealing the upper die seat 7 and the lower die seat 2 and improving the sealing performance between the upper die seat 7 and the lower die seat 2.

[0031] Please refer to Figure 4 In order to facilitate mold opening and closing, the mold closing mechanism 6 in the embodiment comprises a double-shaft motor 601 fixed to the lower surface of the inner cavity of the box body 5. The output shaft of the double-shaft motor 601 is fixed with a second rotating rod 602. The outer surface of the second rotating rod 602 is fixed with a first bevel gear 603. The outer surface of the first bevel gear 603 is threadedly connected with a second bevel gear 604. The lower surface of the second bevel gear 604 is fixed with a second screw rod 605. The double-shaft motor 601 drives the second rotating rod 602 and the first bevel gear 603 to rotate together, thereby driving the second bevel gear 604 and the second screw rod 605 to rotate together. The outer surface of the second screw rod 605 is threadedly connected with a rod sleeve 606. The upper die seat 7 is fixed to the lower surfaces of the two rod sleeves 606. The rod sleeve 606 and the upper die seat 7 are driven to move together through the rotation of the second screw rod 605.

[0032] The lower surface of the box body 5 is provided with two rotating holes, and the second screw rod 605 is rotatably connected to the inside of the rotating hole through a bearing, thereby increasing the stability of the second screw rod 605 during rotation and limiting the second screw rod 605.

[0033] In addition, the left and right sides of the upper die holder 7 are fixedly provided with two connecting blocks which are slidably connected to the outer surface of the connecting rod 4, thereby increasing the stability of the upper die holder 7 during movement.
