[0028] It should be noted that the first hydraulic rod 4 can drive the movable mold 5 to move up and down, and when the movable mold 5 and the fixed mold 6 are engaged with each other, product injection molding can be performed therein.

[0029] like Figure 3 , Figure 4 As shown, the lifting mechanism 7 includes a first motor 71, the lower surface of the first motor 71 is fixedly connected to the right front side of the upper surface of the mechanism frame 2, the output end of the first motor 71 is fixedly connected to the first bevel gear 72, the upper surface of the mechanism frame 2 is rotatably connected to four rectangularly distributed screw rods 73, the outer walls of the two screw rods 73 located on the front side are fixedly connected to the second bevel gear 74 near the bottom, the front side of the second bevel gear 74 located on the right side is meshed and connected with the lower side of the first bevel gear 72, and the outer wall of the screw rod 73 is threadedly connected to the moving plate 711.

[0030] It should be noted that the first motor 71 drives the first bevel gear 72 to rotate. When the first bevel gear 72 rotates, it drives the second bevel gear 74 located on the right side to rotate. When the second bevel gear 74 located on the right side rotates, it drives the screw rod 73 located on the right front side to rotate. When the screw rod 73 rotates, it can drive the movable plate 711 to move up and down.

[0033] like Figure 3 , Figure 4 As shown, the outer walls of the four screw rods 73 are fixedly connected to sprockets 77 near the bottom, and the sprockets 77 are located between the movable plate 711 and the second bevel gear 74. The sides of the two sprockets 77 on the front and rear sides are meshed with chains 78.

[0034] It should be noted that when the screw rod 73 at the front side rotates, the sprocket 77 at the front side is driven to rotate. When the sprocket 77 at the front side rotates, the chain 78 makes the sprocket 77 at the rear side rotate synchronously in the same direction, thereby making the four second bevel gears 74 rotate synchronously.

[0035] like Figure 2 , Figure 3As shown, a top plate 710 is movably sleeved in the middle of the upper surface of the workbench 1, the upper surface of the top plate 710 is flush with the upper surface of the workbench 1, and the top plate 710 is located on the inner side of the fixed mold 6, and four first push rods 79 distributed in a rectangular shape are fixedly connected to the lower surface of the top plate 710 near the four corners, and the lower surface of the first push rods 79 is fixedly connected to the upper surface of the movable plate 711.

[0036] It should be noted that when the movable plate 711 rises, it drives the first push rod 79 to move upward, and when the first push rod 79 moves upward, it drives the top plate 710 to move upward, so that the top plate 710 pushes the injection molded product to separate from the fixed mold 6.

[0037] like Figure 5 , Figure 6 As shown, the two clamping mechanisms 8 both include a protective shell 81, the lower surface of the protective shell 81 is fixedly connected to the left and right sides of the fixed mold 6, a second motor 84 is fixedly connected to the middle of the inner lower surface of the protective shell 81, the output end of the second motor 84 is fixedly connected to a transmission rod 82, the outer wall of the transmission rod 82 is movably sleeved with a mechanism table 83, the middle of the upper surface of the mechanism table 83 is rotatably connected with a fourth bevel gear 85, the inner side of the fourth bevel gear 85 is movably sleeved on the outer wall of the mechanism table 83, the shape of the mechanism table 83 is L-shaped, the side of the fourth bevel gear 85 close to the fixed mold 6 is meshed with a fifth bevel gear 86, the side of the fifth bevel gear 86 close to the fixed mold 6 is rotatably connected to the side wall of the mechanism table 83, the end of the fifth bevel gear 86 close to the fixed mold 6 is fixedly connected to a second connecting rod 87, and the second connecting rod 87 is located on the outside of the protective shell 81.

[0038] It should be noted that the second motor 84 drives the transmission rod 82 to rotate, and when the transmission rod 82 rotates, it drives the fourth bevel gear 85 to rotate, and when the fourth bevel gear 85 rotates, it drives the fifth bevel gear 86 to rotate, and when the fifth bevel gear 86 rotates, it drives the second connecting rod 87 to rotate, so that the lower end of the second connecting rod 87 moves to the front and rear sides of the fixed mold 6.

[0040] It should be noted that the second hydraulic rod 88 can drive the clamping plate 89 to move, so that the clamping plates 89 on both sides clamp the injection molded product. Since the clamping plate 89 is rotatably connected to the second hydraulic rod 88, under the influence of gravity, the injection molded product is always in a vertical state when the second hydraulic rod 88 rotates.

[0041] like Figure 3 , Figure 5 and Figure 6As shown, a second push rod 810 is fixedly connected to the lower surface of the mechanism platform 83 near the front and rear sides, and the lower end of the second push rod 810 is fixedly connected to the upper surface of the moving plate 711 near the left and right sides.

[0042] It should be noted that when the movable plate 711 rises, it will drive the second push rod 810 to move upward, and when the second push rod 810 moves upward, it will drive the mechanism platform 83 to move upward, thereby causing the second hydraulic rod 88 to move upward, so that the product is detached and no longer falls back to the fixed mold 6.

[0043] The working principle of the utility model is as follows: first, the first motor 71 drives the first bevel gear 72 to rotate, and when the first bevel gear 72 rotates, it drives the second bevel gear 74 on the right side to rotate, and when the second bevel gear 74 on the right side rotates, it drives the screw rod 73 on the right front side to rotate, and when the screw rod 73 rotates, it can drive the movable plate 711 to move up and down, and when the second bevel gear 74 on the right side rotates, it drives the third bevel gear 76 on the right side to rotate, and the third bevel gear 76 on the left side rotates synchronously in the same direction by relying on the first connecting rod 75, so that the two screw rods 73 on the front side rotate synchronously, and when the screw rod 73 on the front side rotates, it drives the sprocket 7 on the front side. 7 rotates, when the sprocket wheel 77 on the front side rotates, the chain 78 makes the sprocket wheel 77 on the rear side rotate synchronously in the same direction, thereby making the four second bevel gears 74 rotate synchronously, when the moving plate 711 rises, it drives the first push rod 79 to move upward, and when the first push rod 79 moves upward, it drives the top plate 710 to move upward, so that the top plate 710 pushes the injection molded product to separate from the fixed mold 6, when the moving plate 711 rises, it drives the second push rod 810 to move upward, and when the second push rod 810 moves upward, it drives the mechanism table 83 to move upward, thereby making the second hydraulic rod 88 move upward, so that the product separates from the fixed mold 6 and no longer falls back, and the top plate 710 is driven to rise by the first motor 71, so that the injection molded product is separated from the fixed mold 6. When the molded product is separated from the fixed mold 6, the second hydraulic rod 88 rises synchronously, and then the second hydraulic rod 88 pushes the clamping plate 89 to clamp the injection molded product. When the injection molded product follows the movable mold 5, the second hydraulic rod 88 can also directly push the clamping plate 89 to clamp, so that the injection molded product can complete the demoulding operation whether it is on the movable mold 5 or the fixed mold 6. The structure is simple and can be applied to various situations. Finally, the second motor 84 drives the transmission rod 82 to rotate. When the transmission rod 82 rotates, it drives the fourth bevel gear 85 to rotate. When the fourth bevel gear 85 rotates, it drives the fifth bevel gear 86 to rotate. When the fifth bevel gear 86 rotates, it drives the second connecting rod 87 to rotate, so that the lower end of the second connecting rod 87 moves to On the front and rear sides of the fixed mold 6, the second hydraulic rod 88 can drive the clamping plate 89 to move, so that the clamping plates 89 on both sides clamp the injection molded product. Since the clamping plates 89 are rotatably connected to the second hydraulic rod 88, under the influence of gravity, the injection molded product is always in a vertical state when the second hydraulic rod 88 rotates. The second hydraulic rod 88 pushes the clamping plate 89 to clamp the injection molded product. The second motor 84 drives the second hydraulic rod 88 to rotate, so that the injection molded product is separated from the top of the fixed mold 6. Finally, the second hydraulic rod 88 brings back the clamping plate 89 so that the injection molded product falls to complete the unloading. At the same time, the second hydraulic rod 88 can rotate in both directions, so that the front and rear sides of the stand 3 can be unloaded.
