Description

Technical Field

[0001] The invention relates to the technical field of rubber soles, in particular to a puncture-proof rubber sole and a manufacturing method thereof. Background Art

[0002] Labor protection shoes, also known as safety shoes or protective shoes, are shoes specially designed to protect workers' feet from injury. They are widely used in various working environments, especially in those occasions where there is a potential risk of foot injury, such as construction sites, factory production lines, etc. Among them, the sole of labor protection shoes is its key component, which not only affects the comfort of the shoes, but is also directly related to the protective performance.

[0003] For example, the Chinese patent "An indoor measuring device for decorative design" with announcement number CN221641491U includes a base, a molded portion is arranged at the upper end of the base, a cleaning portion is arranged at one side of the base, the upper end of the molded portion is a rotating bracket, which is used to drive the labor protection shoes to rotate to a predetermined position for picking and placing operations, and the upper and lower ends of the rotating bracket are provided with transfer columns, a foot mold fixed end is arranged above the base, a foot mold moving end is arranged at one end of the foot mold fixed end, the foot mold fixed end is installed at the bottom of one end of the transfer column, and an inner ring is slidably installed on the outer side of one end of the transfer column The outer side of the inner ring frame is provided with an outer ring frame for driving the mobile end of the foot mold to recover, and a connecting frame plate for driving the mobile end of the foot mold to move is rotatably installed on one side of the lower end of the outer ring frame, and side panels that can be rotatably stored inward are provided on both sides of the fixed end of the foot mold, and a protruding positioning seat is provided on the inner side adjacent to the upper end of the cleaning part, and the positioning seat is used to position the labor protection shoe, and a cutting knife is provided inside one end of the positioning seat for scraping off protruding waste at the edge of the sole of the labor protection shoe, and a protruding fixed platform is provided inside the mobile end of the foot mold, and the upper end of the fixed platform is rotatably connected to the connecting frame plate.

[0004] Although the above-mentioned prior art can realize the use of labor protection shoes, in actual use, on the one hand, the soles are easily punctured by sharp objects. Usually, when a worker steps on a sharp object while wearing a labor protection shoe, the sharp object will pierce the rubber sole and penetrate into the sole of the worker's foot, thereby posing a threat to the worker's personal safety. On the other hand, the replacement of the sole manufacturing mold is not flexible enough. Usually, the sole manufacturing mold is usually fixed, resulting in the need to dismantle the entire fixed structure when replacing the sole mold of different sizes, thereby increasing the workload of the operator. Therefore, it does not meet the existing needs. In this regard, we propose a puncture-proof rubber sole and a manufacturing method thereof. Summary of the invention

[0017] Step 1: Before manufacturing, align the positioning slot opening on the fixed die with the threaded rod and move the fixed die downward until the first fixed die contacts the manufacturing table. Repeat the above steps until the remaining two fixed dies are stacked. Then align the nut opening with the threaded rod and turn the nut so that the nut is turned downward on the threaded rod through the thread until the nut contacts the fixed die and causes extrusion. At this time, turn on the servo motor so that the output shaft of the servo motor drives the screw rod to rotate, and the extrusion plate is driven to move in the slide slot through the screw rod until the extrusion plate is moved to a suitable position. At this time, the rubber pad on the extrusion plate contacts the side wall of the fixed die.

[0018] Step 2: When adjusting the first movable mold and the second movable mold, first align the fixing seat with the opening of the limiting cavity and push it into the limiting cavity. At this time, move the fixing seat, and drive the first movable mold to move together through the connecting rod fixedly connected to the fixing seat until the first movable mold is moved to a suitable position. At this time, install a suitable second movable mold according to the specific shoe size. First, align the insertion rod on the second movable mold with the opening of the slot and insert it into the slot until the second movable mold fits the first movable mold. At this time, use the second bolt to fix the second movable mold on the first movable mold;

[0019] Step three: during manufacturing, first put the heated composite anti-skid layer into the fixed mold, and evenly apply shoe glue on the upper end of the composite anti-skid layer. Then put the heated composite anti-puncture layer into the fixed mold, make the composite anti-puncture layer contact with the composite anti-skid layer, and evenly apply shoe glue on the upper end of the composite anti-puncture layer. Finally, put the heated composite thermal insulation layer into the fixed mold. At this time, turn on the hydraulic telescopic device to extend the telescopic end of the hydraulic telescopic device.

At the same time, the second movable mold and the first movable mold squeeze the composite anti-skid layer, the composite anti-puncture layer and the composite thermal insulation layer. After maintaining the squeezing state for a period of time, the formed sole body is taken out from the fixed mold.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention can improve the puncture resistance of the sole by providing a composite puncture-proof layer. The puncture-proof outer layer can improve the puncture resistance of the sole. The puncture-proof outer layer can effectively prevent sharp objects from penetrating further, thereby avoiding damage to the wearer's feet. The puncture-proof reinforcement layer can enhance the protective performance of the shoe. At the same time, for workers who need to stand or walk for a long time, the puncture-proof reinforcement layer has a certain supporting force, which helps to alleviate labor injuries to the sole. The puncture-proof inner layer can improve the comfort of the sole. The puncture-proof inner layer can absorb the impact force fed back to the foot by the ground when walking or jumping, thereby reducing the burden on the foot and improving the wearing comfort.

[0022] (2) The present invention can quickly install and fix the fixed mold through the threaded rod and the extrusion plate. First, align the opening of the positioning groove on the fixed mold with the threaded rod and move the fixed mold downward until the first fixed mold contacts the manufacturing table. Repeat the above steps until the remaining two fixed molds are stacked. At this time, align the opening of the nut with the threaded rod and rotate the nut so that the nut rotates downward on the threaded rod through the thread until the nut contacts the fixed mold and causes extrusion. At this time, turn on the servo motor so that the output shaft of the servo motor drives the screw rod to rotate, and the extrusion plate is driven by the screw rod to move in the slide groove until the extrusion plate is moved to a suitable position. At this time, the rubber pad on the extrusion plate contacts the side wall of the fixed mold, thereby improving the installation efficiency of the fixed mold.

[0023] (3) The present invention can adjust the positions of the first movable mold and the second movable mold through the fixing seat and the insertion rod. When adjusting the first movable mold and the second movable mold, first align the fixing seat with the opening of the limiting cavity and push it into the limiting cavity. At this time, move the fixing seat, and drive the first movable mold to move together through the connecting rod fixedly connected to the fixing seat until the first movable mold is moved to a suitable position. At this time, install a suitable second movable mold according to the specific shoe size. First, align the insertion rod on the second movable mold with the opening of the slot and insert it into the slot until the second movable mold fits the first movable mold. At this time, use the second bolt to fix the second movable mold on the first movable mold, thereby improving the flexibility of the first movable mold and the second movable mold.
