[0001] The utility model belongs to the technical field of production molds for sanitary product packaging bags, and specifically, it is a punching template for the gourd-shaped bag body of sanitary products. Background Technique
[0002] In recent years, with the increasingly fierce market competition, the bag body structures of sanitary product packaging bags have shown a diversified development trend. The common square bag body can no longer meet the special market demands. Subsequently, special-shaped bag bodies such as triangular, trapezoidal, and gourd-shaped ones are gradually favored by the market.
[0003] Most of the existing ordinary square-structured sanitary product packaging bags adopt the flexographic printing process and realize the batch production of packaging bags through heat sealing and forming machines. For the bag bodies of special-shaped sanitary product packaging bags such as triangular, trapezoidal, and gourd-shaped ones, the conventional production processes have problems such as complex procedures, high control difficulty, and high production costs. Therefore, researching a forming template suitable for the production of gourd-shaped bag bodies, which can perform punching production quickly, is of great significance for the production of packaging bag manufacturers.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: A punching template for the gourd-shaped bag body of sanitary products includes a bottom plate, on which punching blades are provided, and the punching blades are in a gourd structure; several ejector blocks are provided on the surface of the bottom plate, and the ejector blocks are located around the punching blades; mounting bolt holes are also provided on the back of the bottom plate.
[0006] As an improvement, the bottom plate is in a square structure, and rounded corners are provided at the four corners.
[0007] As an improvement, the size of the rounded corners is R3 - R10mm.
[0008] As an improvement, the punching blade includes two left and right symmetric S-shaped segments and a bottom arc segment.
[0009] As an improvement, the punching blade is a metal knife and protrudes 0.5 - 2.5mm above the plane of the bottom plate.
[0010] As an improvement, the ejector blocks are elastic rubber cubes, and the number is 4 - 8.
[0011] As an improvement, the ejector block is fixedly embedded by arranging grooves of the same size on the surface of the bottom plate, and polyurethane glue is used for enhanced bonding.
[0012] As an improvement, the height of the ejector block above the punching blade is 1 - 3 mm.
[0013] As an improvement, there are 4 installation bolt holes in total, which are symmetrically distributed at the four corners on the back of the bottom plate, improving the installation and positioning accuracy of the punching template.
[0014] As an improvement, the bottom plate is of a metal plate structure, and the punching blade is fixed by spot welding through a clamping groove arranged on the surface of the bottom plate.
[0015] The beneficial effects achieved by the present utility model are as follows: A punching template for a hygienic product gourd bag body has the characteristics of simple structure, good fixing stability, high punching efficiency, and low use cost; by inlaying a gourd-shaped punching blade on a metal bottom plate, the gourd bag body structure can be punched and formed at one time, facilitating subsequent direct heat sealing and bonding, and improving the production efficiency of the gourd bag body; by arranging rubber ejector blocks around the punching blade, it is avoided that the punched bag body is embedded inside the blade, effectively improving the punching efficiency; in addition, installation bolt holes are arranged on the back of the bottom plate, improving the installation and fixing reliability of the metal bottom plate, and at the same time, the installation and positioning accuracy of the template is also correspondingly improved.

[0020] The following further describes the present utility model in detail in conjunction with the drawings and the embodiments: As Figures 1 to 3 shown, a punching template for a hygienic product gourd bag body of the present utility model includes a bottom plate 1, a punching blade 2 is arranged on the bottom plate 1, and the punching blade 2 is in a gourd structure; a plurality of ejector blocks 3 are arranged on the surface of the bottom plate 1, and the ejector blocks 3 are located around the punching blade 2; installation bolt holes 4 are also arranged on the back of the bottom plate 1.
[0021] Furthermore, the base plate 1 is a square structure, and four corners are provided with chamfered corners 5; specifically, the size of the chamfered corners 5 is R3~R10mm, preferably R5~R8mm. By providing the chamfered corners 5, the four sharp corners of the metal base plate can be prevented from being damaged during installation and disassembly.
[0022] Furthermore, the punching blade 2 includes two left-right symmetrical S-shaped segments 21 and a bottom arc segment 22; specifically, the S-shaped segment 21 is a parallel double-blade structure, and the arc segment 22 is a single-blade structure; further, the punching blade 2 is a metal knife, and is 0.5~2.5mm higher than the plane of the bottom plate 1, preferably 0.5~1.5mm, so as to ensure that the punching wear of the low knife is smaller and the efficiency is higher.
[0023] Furthermore, the ejector block 3 is an elastic rubber block, and the number is 4 to 8, preferably 6; specifically, the ejector block 3 is embedded and fixed by setting a groove of the same size on the surface of the bottom plate 1, and polyurethane glue is used to enhance the bonding, thereby preventing the ejector block 3 from falling off during repeated rapid work; more specifically, the ejector block 3 is 1 to 3 mm higher than the punching blade 2, preferably 1.5 to 2.5 mm, thereby effectively preventing the punched bag body from being embedded in the inside of the punching blade, thereby improving the punching efficiency.
[0024] Furthermore, there are 4 mounting bolt holes 4, which are symmetrically distributed on the four corners of the back of the bottom plate 1, thereby improving the fixing reliability of the punching template and the installation positioning accuracy;
