[0033] Reference Figure 2 - Figure 4 The upper template 5 is connected to the output shaft of the cylinder 3 through a protective mechanism 6. The protective mechanism 6 includes a connecting column 61, which is fixedly connected to the top of the upper template 5. An air pressure chamber 62 is provided on the inner wall of the upper template 5. The upper end of the air pressure chamber 62 is opened in the middle of the connecting column 61. The air pressure chamber 62 is divided into two parts, one part of which is inside the connecting column 61, and the other part is on the inner wall of the upper template 5. The inner wall piston of the air pressure chamber 62 is connected with a push block 63. The initial position of the push block 63 is that the upper part is inside the air pressure chamber 62, and the lower part is below the air pressure chamber 62. The top of the push block 63 is elastically connected to the inner wall of the air pressure chamber 62 by a spring 64. One end of the spring 64 is fixedly connected to the top of the push block 63, and the other end of the spring 64 is fixedly connected to the inner wall of the air pressure chamber 62.

[0034] Reference Figure 2 - Figure 4 The piston on the top inner wall of the air pressure chamber 62 is connected to a slide plate 65, and the top of the slide plate 65 is fixedly connected to a control rod 66. The control rod 66 is in the middle of the slide plate 65. The left and right ends of the control rod 66 are hinged with connecting rods 67. The end of the connecting rod 67 away from the control rod 66 is hinged with a sleeve 68. The sleeve 68 is a rectangular parallelepiped with an open end away from the control rod 66. The inner wall of the sleeve 68 is slidably connected with a block 69. The cross-sectional shape of the block 69 is trapezoidal, and the top length of the block 69 is shorter than the bottom length. The initial state of the connecting rod 67 is horizontal. The end of the block 69 close to the control rod 66 is elastically connected to the inner wall of the sleeve 68 by a second spring 610. One end of the second spring 610 is fixedly connected to the end of the block 69 close to the control rod 66, and the other end of the second spring 610 is fixedly connected to the inner wall of the sleeve 68.

[0035] Reference Figure 2- Figure 4 The outer wall of the connecting column 61 is slidably connected with a connecting block 611. The connecting block 611 is in the shape of a hollow cylinder. The top of the connecting block 611 passes through and is fixedly connected to the output shaft of the cylinder 3. The outer wall of the connecting column 61 fits with the inner wall of the connecting block 611. The top of the bracket 2 is provided with a through hole with a diameter larger than the outer diameter of the connecting block 611. Through the setting of the through hole, the connecting block 611 can smoothly pass through the bracket 2. The inner wall of the connecting block 611 is provided with a bayonet 612. The height of the bayonet 612 matches the height of the block 69.

[0036] Reference Figure 1 、 Figure 2 and Figure 5 The lower template 4 is connected to the upper template 5 through a positioning assembly 7. The positioning assembly 7 includes a rotating rod 71. The shape of the rotating rod 71 is set to be a shape formed by connecting a cylinder with a larger diameter and a long plate. The end of the rotating rod 71 close to the lower template 4 is rotatably connected to the outer wall of the lower template 4. The end of the rotating rod 71 close to the cylinder 3 is fixedly connected to a positioning block 72. The surface of the lower template 4 is provided with a groove with a shape consistent with half of the shape of the positioning block 72. The outer wall of the upper template 5 is provided with a positioning groove 73. The shape of the positioning groove 73 is a quarter-circular ring groove. The left end of the positioning groove 73 is connected to the lower area of ​​the upper template 5. The left side depth of the positioning groove 73 is deeper than the right side depth. The right side depth of the positioning groove 73 is consistent with the length of the positioning block 72.

[0037] Working principle: During use, when the staff needs to dock the mold, they first start the cylinder 3, so that the output shaft of the cylinder 3 drives the upper template 5 to move downward. When the bottom end of the upper template 5 contacts the surface of the lower template 4, the push block 63 is squeezed and moves upward relative to the upper template 5. Therefore, the area of ​​the push block 63 entering the air pressure chamber 62 increases, so the pressure inside the air pressure chamber 62 increases, and the slide 65 moves upward under the action of the air pressure.

[0038] When the slide 65 moves upward, the end of the connecting rod 67 close to the slide 65 moves upward, and since the sleeve 68 cannot move in the vertical direction, the connecting rod 67 changes from its original horizontal state to an inclined state. Therefore, the projected length of the connecting rod 67 in the horizontal state is reduced. Therefore, the sleeve 68 moves toward the side close to the slide 65 under the drive of the connecting rod 67, and drives the block 69 to move toward the end close to the connecting rod 67.

[0039] After the block 69 moves inward until the inclined surface is flush with the edge of the connecting column 61, the outer wall of the connecting block 611 squeezes the inclined surface at the top of the block 69, so that the block 69 is forced to move into the inside of the sleeve 68, and the connecting block 611 can continue to move downward under the drive of the output shaft of the cylinder 3, but the upper template 5 will not be squeezed at this time, so during the docking process, the docking point will not be damaged due to excessive force on the upper template 5.

[0040] When the docking is completed, the staff closes the cylinder 3 and rotates the rotating rod 71 so that the positioning block 72 enters the positioning groove 73. Since the left end of the positioning groove 73 is deeper, the positioning block 72 can smoothly enter the interior of the positioning groove 73, and in the process of rotation, the depth of the inner wall of the positioning groove 73 gradually changes, causing a slight change in the horizontal position of the upper template 5. When the four positioning blocks 72 in front, behind, left and right of the lower template 4 are rotated, the outer walls of the lower template 4 and the upper template 5 are exactly in the same horizontal position. Therefore, it is not easy for the finished product to have defects due to the offset of the horizontal position during the docking process.

[0041] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
