[0030] Further, such as Figure 2 and Figure 4 As shown, the upper demolding assembly 6 includes a through slot 61 and a push plate 62. The through slot 61 is opened on the side of the upper template 4 close to the sliding plate 3. The length of the through slot 61 is equal to the length of the upper template 4. The length of the push plate 62 is greater than the length of the through slot 61. The push plate 62 is slidably connected in the through slot 61.

[0031] Further, such as Figure 2-Figure 4As shown, the upper demoulding assembly 6 also includes a spring 63, a push block 64 and a fixed rod 65. The two ends of the multiple springs 63 are respectively fixedly connected to the through groove 61 and the push plate 62. The springs 63 are distributed in a linear array on the push plate 62. The push block 64 is fixedly connected to the push plate 62. The push block 64 is slidably connected to the upper template 4. The push block 64 is made of rubber. The protective shell is demoulded by the push block 64, which can reduce the damage to the protective shell. The two fixed rods 65 are fixedly connected to the four fixed blocks 56. The length of the push plate 62 is equal to the spacing between the two fixed rods 65 plus the length of the two fixed rods 65. When the upper template 4 is separated from the lower template 2, under the action of the spring 63, the push plate 62 is pushed to move in the direction of the protective shell, driving the push block 64 to move, and the push block 64 is used to separate the protective shell from the upper template 4.

[0032] Further, such as Figure 2-Figure 6 As shown, the lower demoulding assembly 7 includes a groove 71 and a connecting column 72. The groove 71 is opened at the bottom of the lower mold plate 2. The connecting column 72 is rotatably connected to the lower mold plate 2. The length of the connecting column 72 is equal to the length of the rotating column 52. The connecting column 72 is always parallel to the rotating column 52.

[0033] Further, such as Figure 3-Figure 6 As shown, the lower mold plate 2 assembly also includes a transmission belt 73 and a bidirectional screw 74. The transmission belt 73 is sleeved on the rotating column 52 and the connecting column 72. The rotating column 52 cooperates with the transmission belt 73 to drive the connecting column 72 to rotate. The two bidirectional screws 74 are fixedly connected to the connecting column 72. The two bidirectional screws 74 are symmetrical with the injection tube 8 as the axis.

[0034] Further, such as Figure 2-Figure 6 As shown, the lower demoulding assembly 7 also includes a threaded block 75, a through hole 76 and a rotating rod 77. The four threaded blocks 75 are respectively threadedly connected to the two ends of the two bidirectional screws 74. The height of the four threaded blocks 75 is equal to the height of the groove 71. Two through holes 76 are opened on the lower template 2. The cross-section of the through hole 76 is "T" shaped. The two threaded blocks 75 on the same bidirectional screw 74 are symmetrical about the corresponding through holes 76. A plurality of rotating rods 77 are respectively rotatably connected to the four threaded blocks 75. Two rotating rods 77 are provided on one threaded block 75. The two rotating rods 77 are symmetrical about the connecting column 72.

[0035] Further, such as Figure 3-Figure 6As shown, the lower template 2 also includes a top plate 78 and a sealing plate 79. The two top plates 78 are respectively slidably connected in the two through holes 76. The two top plates 78 are respectively rotatably connected to a plurality of rotating rods 77. The two top plates 78 are symmetrical with the injection tube 8. The two sealing plates 79 are respectively fixedly connected to the two top plates 78. The sealing plates 79 are movably inserted in the through holes 76. The sealing plates 79 are made of rubber. The sealing plates 79 are used to push the protective shell to be demoulded, which can reduce damage to the protective shell. When the protective shell is unloaded, the transmission belt 73 is used to drive the connecting column 72 to rotate, so that the bidirectional screw 74 rotates, pushing the threaded block 75 to move, and the rotating rod 77 is used to push the top plate 78 to separate the protective shell from the lower template 2, thereby completing the demoulding of the protective shell.

[0036] Further, such as Figure 2-Figure 4 As shown, a sealing strip 9 and a sealing groove 10 are provided on the fixed plate 1. The sealing strip 9 is fixedly connected to the upper template 4. The cross section of the sealing strip 9 is in the shape of a Chinese character "U". The sealing groove 10 is provided on the lower template 2. The cross section of the sealing groove 10 is in the shape of a Chinese character "U". The sealing strip 9 and the sealing groove 10 cooperate to enhance the sealing between the lower template 2 and the upper template 4. The sealing strip 9 is adapted to the sealing groove 10.

[0037] The specific working method is as follows: the raw material is poured into the space between the upper template 4 and the lower template 2 through the injection molding tube 8 for shaping. After the protective shell is formed, the motor 51 is started, and its output shaft drives the rotating column 52 to rotate, and the connecting plate 53 rotates accordingly. Since the connecting plate 53 is rotatably connected to the slide plate 54, and the slide plate 54 is slidably connected to the slide groove 55 of the sliding plate 3, the slide plate 54 moves in the slide groove 55 as the connecting plate 53 rotates, pushing the sliding plate 3 to move up along the limiting column 57. At this time, the push plate 62 moves downward as the upper template 4 moves upward under the action of the spring 63, pushing the push block 64 to move downward, and pushing the protective shell out of the upper template 4. At the same time, the lower template 2 rotates as the rotating column 52 rotates, and under the action of the transmission belt 73, The connecting column 72 is driven to rotate, and the bidirectional screw 74 rotates accordingly. Since the threaded block 75 is threadedly connected to the two ends of the bidirectional screw 74, the two threaded blocks 75 located on the same bidirectional screw 74 move toward each other. Since the two ends of the rotating rod 77 are respectively rotatably connected to the threaded block 75 and the top plate 78, the rotating rod 77 rotates with the movement of the threaded block 75, pushing the top plate 78 to move in the direction of the protective shell, and using the sealing plate 79 on the top plate 78 to push the protective shell out of the lower template 2. At this time, the protective shell is separated from the upper template 4 and the lower template 2, and the protective shell rotates with the rotation of the lower template 2. When the lower template 2 rotates to be perpendicular to the fixed plate 1, the protective shell will flip out of the lower template 2 due to its own weight, thereby completing the automatic unloading of the protective shell.

[0038] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
