Description

Technical Field

[0002] Finger cots, also known as finger sleeves, are a type of protective equipment widely used in medical and daily life applications. A mold for producing finger cots refers to a fixed mold used to manufacture finger cots. By shaping the finger cot onto the mold head and then demolding it, rapid production of finger cots is achieved. Existing patent CN202420087600 discloses a semi-ellipsoidal closed-end mold, but its groove depth is relatively deep, which is not conducive to demolding and cannot simultaneously meet the requirements of anti-slip and demolding efficiency. Furthermore, some molds have randomly distributed grooves, which can easily lead to uneven latex application during the molding process, affecting the consistency of the finished product's thickness.

It should be noted that the size and shape of the base 3 can be selected according to actual needs.

[0030] This utility model provides a finger sleeve mold. Compared with the prior art, the use of dotted grooves 2 and threaded grooves 4 allows the finger sleeve formed by the mold with glue-coated thickness to have raised dots and threads, which can increase the friction of the finger sleeve itself and increase its anti-slip performance. The staggered arrangement of adjacent rows of dotted grooves 2 can control the distance between the grooves, effectively avoiding the appearance of grooves in the middle of the grooves after diamond blasting, and effectively increasing the groove density.

[0031] Example 1

[0032] A finger sleeve mold includes a finger sleeve mold body 1, which has a cylindrical shape. The top end of the finger sleeve mold body 1 is a closed end, and the tail end is a connecting end. The closed end is semi-ellipsoidal in shape. A base 3 is fixedly connected to the connecting end of the finger sleeve mold body 1. The base 3 facilitates the connection and fixing of the finger sleeve mold to the production line machine, and the size and shape of the base can be selected according to actual needs.

[0033] The surface of the finger sleeve mold body 1, from the closed end to the connecting end, is sequentially provided with a first region 5, a second region 6, a third region 7, and a fourth region 8. Each of these regions has a groove structure. Specifically, the grooves in the first region 5 are dot-shaped grooves. The grooves in the second region 6 are threaded grooves. The grooves in the third region 7 are dot-shaped grooves. The grooves in the fourth region 8 are threaded grooves. The total length from the closed end to the central axis of the fourth region 8 is 70-100 mm. Specifically, the first region 5 to the fourth region 8 of the finger sleeve mold is a continuous, smoothly transitioning, integral structure.

[0034] In this embodiment, the first region 5 has six rows of dot-shaped grooves 2 extending from the closed end to the connecting end. The dot-shaped grooves 2 are circular. The cross-sectional profile of the recessed area is hemispherical. The circular dot-shaped grooves 2 are evenly distributed along the circumference within the same row, dividing the circumference into 10-16 equal parts. The central angle between adjacent dot-shaped grooves 2 is 360° / 10-16. The distance between adjacent circular dot-shaped grooves 2 within the same row is 2-5 mm, and adjacent rows of circular dot-shaped grooves 2 are staggered, with an offset of half a distance (1.0-2.5 mm). The spacing between the five rows of the six rows of dot-shaped grooves is unequal, with a spacing ratio of 1:(1.5-2):(2.5-3.5):(4-5):(5-8) (from the closed end to the connecting end). The diameter of the dot-shaped grooves is 0.6-1.2 mm, and the depth is 0.3-0.6 mm. The spacing between adjacent dot-shaped grooves 2 in the same row is 3-5mm, and the spacing between adjacent rows of dot-shaped grooves 2 is 2-5mm.

[0035] In this embodiment, the third region 7 has six rows of dot-shaped grooves 2 extending from the closed end to the connecting end. The dot-shaped grooves 2 are circular. The cross-sectional profile of the recessed area is hemispherical. The circular dot-shaped grooves 2 are evenly distributed along the circumference within the same row, dividing the circumference into 10-16 equal parts. The central angle between adjacent dot-shaped grooves 2 is 360° / 10-16. The distance between adjacent circular dot-shaped grooves 2 within the same row is 2-5 mm. Adjacent rows of circular dot-shaped grooves 2 are staggered, with an offset of half a distance (1.0-2.5 mm). The spacing between the five rows of the six rows of dot-shaped grooves is unequal, with a spacing ratio of 1:(1.5-2):(2.5-3.5):(4-5):(5-8) (from the closed end to the connecting end). The diameter of the dot-shaped grooves is 0.6-1.2 mm, and the depth is 0.3-0.6 mm.

[0036] In this embodiment, the threaded groove 4 of the second region 7 has five rows from the closed end to the connecting end. Specifically, the threaded groove 4 is an annular recess with a depth of 0.1-0.5 mm, a width of 0.2-1 mm, and a spacing of 1-4 mm. The spacing between the four rows of threads is unequal, with a spacing ratio of 1:(1.5-2):(2.5-3.5):(4-5) (from the closed end to the connecting end), used to increase the longitudinal friction of the finger sleeve.

[0037] In this embodiment, the threaded groove 4 of the fourth region 8 has five rows from the closed end to the connecting end. Specifically, the threaded groove 4 is an annular recess with a depth of 0.1-0.5 mm, a width of 0.2-1 mm, and a spacing of 1-4 mm. The spacing between the four rows of threads is unequal, with a spacing ratio of 1:(1.5-2):(2.5-3.5):(4-5) (from the closed end to the connecting end), used to increase the longitudinal friction of the finger sleeve.

[0038] In this embodiment, the finger sleeve mold body 1 and the base 3 are an integral structure. This facilitates the preparation and production of the finger sleeve mold. The finger sleeve mold body 1 is made of quartz or glass.

[0039] In this embodiment, the dotted grooves 2 can be made into circular patterns by diamond blasting and film application. The threaded grooves 4 can be processed by CNC engraving to ensure the continuity and precision of the annular recesses.

[0040] The finger sleeve mold provided in this embodiment has the following characteristics: the dotted grooves 2 are turned outwards after latex dipping and demolding, forming dotted protrusions to increase the local friction of the finger sleeve; the threaded grooves 4 increase the longitudinal friction of the finger sleeve and reduce the demolding difficulty; the composite structure improves the anti-slip performance and demolding efficiency of the finger sleeve; the staggered arrangement of the dotted grooves 2 increases the uniformity of the finger sleeve thickness and reduces the risk of processing defects (such as groove adhesion). The circumferential design of the grooves equally divides the circumference to solve the problem of uneven latex dipping caused by the uneven distribution of traditional grooves, improving the consistency of the finished product thickness. Through the alternating arrangement of the dotted grooves 2 and the threaded grooves 4, while ensuring equal division, the groove coverage density is increased by half-spacing offset, improving the surface functionality of the finger sleeve and enhancing the uniformity and functionality of the finished product.

The outer surface of the main body 1 has dotted grooves 2 and threaded grooves 4; the dotted grooves 2 and threaded grooves 4 are alternately arranged from one end to the other. The dotted grooves 2 are hemispherical in shape and 0.5 mm deep. The threaded grooves 4 are 0.2 mm deep, 0.5 mm wide, and have a circumferential spacing of 4 mm. This design reduces the thickness variation of the finished finger sleeves by 35%-40% and improves demolding efficiency by 20%.
