[0020] Reference Figure 1-4 A mold for preparing a lead-acid battery box includes a template 1, a material injection pipe 2 is installed at the center of the top of the template 1, six cylinders 3 are symmetrically installed on the top wall of the template 1, and every three cylinders 3 are arranged in a row and at equal intervals, and a flow channel 4 is provided in the template 1;

[0021] The flow channel 4 includes a main pipe 41 corresponding to the bottom end of the injection pipe 2, and the bottom end of the main pipe 41 is connected to two first branch pipes 42 and two second branch pipes 43. The two first branch pipes 42 are symmetrically arranged with the main pipe 41 as the center, and the two second branch pipes 43 are symmetrically arranged with the main pipe 41 as the center. Each end of the first branch pipe 42 away from the main pipe 41 is connected to a third branch pipe 44, and the third branch pipe 44 and the second branch pipe 43 are perpendicular to each other. Each end of the second branch pipe 43 away from the main pipe 41 is connected to a sixth branch pipe 47, and the sixth branch pipe 47 and the second branch pipe 43 are perpendicular to each other. Both ends of each third branch pipe 44 are connected to a fourth branch pipe 45, and the fourth branch pipe 45 and the third branch pipe 44 are mutually perpendicular. Vertically, the bottom end of each sixth branch pipe 47 and the side away from the second branch pipe 43 are connected with three seventh branch pipes 48, and the seventh branch pipe 48 and the sixth branch pipe 47 are perpendicular to each other, both ends of each fourth branch pipe 45 are connected with the fifth branch pipe 46, and the bottom wall of each seventh branch pipe 48 away from the sixth branch pipe 47 is also connected with the fifth branch pipe 46, and each fifth branch pipe 46 is provided with a cut-off hole 49 on the side close to its bottom end and away from the center of the template 1, and the bottom end of each fifth branch pipe 46 extends to the bottom wall of the template 1 and is installed with a discharge pipe 6, and adjustable cut-off valves 5 are provided on both sides of the template 1, and the end of each cut-off valve 5 extends into the fifth branch pipe 46 through the cut-off hole 49;

[0022] A linkage plate 7 is installed between the three cylinders 3 on the same side, and the linkage plate 7 is located on the lower side of the piston of the cylinder 3 on the same side and fixed thereto. Seven valve needles 8 are provided on the lower side of each linkage plate 7, and each valve needle 8 extends into the discharge pipe 6 through the fifth branch pipe 46 on the same side and cooperates with the nozzle gap of the discharge pipe 6.

[0023] The aperture of the first branch pipe 42 is larger than that of the second branch pipe 43 . The apertures of the first branch pipe 42 , the third branch pipe 44 , the fourth branch pipe 45 and the fifth branch pipe 46 are the same. The apertures of the second branch pipe 43 , the sixth branch pipe 47 and the seventh branch pipe 48 are the same.

[0024] Each shut-off valve 5 is threadedly connected to the template 1 , and the end of the shut-off valve 5 is clearance-matched with the shut-off hole 49 on the fifth branch pipe 46 .

[0025] In the present invention, the molten raw material is injected into the runner 4 in the template 1 through the injection pipe 2. The specific process is: the raw material in the injection pipe 2 flows into the first branch pipe 42 and the second branch pipe 43 through the main pipe 41, and the raw material in the first branch pipe 42 flows into the lower discharge pipe 6 according to the path of the third branch pipe 44, the fourth branch pipe 45, and the fifth branch pipe 46. At the same time, the raw material in the second branch pipe 43 flows into the lower discharge pipe 6 according to the path of the sixth branch pipe 47, the seventh branch pipe 48, and the fifth branch pipe 46.

[0026] The raw materials in any of the above paths can eventually flow to the discharge pipe 6 in equal and uniform amounts. The reason is that the apertures of the first branch pipe 42, the third branch pipe 44, and the fourth branch pipe 45 are all larger than the apertures of the second branch pipe 43, the sixth branch pipe 47, and the seventh branch pipe 48. At the same time, the total path lengths of the second branch pipe 43, the sixth branch pipe 47, and the seventh branch pipe 48 are smaller than the total path lengths of the first branch pipe 42, the third branch pipe 44, and the fourth branch pipe 45, thereby ensuring that the raw materials reaching each fifth branch pipe 46 are equal and uniform.

[0027] In addition, the setting of the shut-off valve 5 can control and adjust the flow rate in the fifth branch pipe 46 by rotating the shut-off valve 5 to control the length of the end of the shut-off valve 5 entering the fifth branch pipe 46 .

[0028] The three cylinders 3 in each row operate simultaneously and drive the linkage plate 7 through their pistons. With the help of the linkage plate 7, the fifth branch pipe 46 in each valve needle 8 and the discharge pipe 6 are driven to move up and down to control the opening and closing of the nozzle of the discharge pipe 6.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
