Problems solved by technology

[0002] At present, with the development and popularization of sports and fitness, sports such as football, basketball, cycling, mountain climbing, and pulleys have attracted the participation of the general public. During sports, especially joints, some injuries will inevitably occur. Many athletes will wear knee pads. To prevent joint injuries, the knee pads currently on the market are generally knitted fabrics, or thickened at the knees, and are generally filled with foam, cotton and other materials to act as a barrier. The knees only have a certain anti-scratch and shock-absorbing effect. Unable to achieve strong mitigation and dispersion of impact

Embodiment 1

[0032] Such as Figure 1-10 As shown, the integrated infusion-molded anti-collision knee pad includes a knee pad body 12 and a crash pad 8, the crash pad 8 is fixed on the knee pad body 12 through a sewing fixing line 13, and the crash pad 8 sequentially includes an integrally molded textile Cloth 2, upper TPU film 3, PU foam layer 4 and lower TPU film 5, the crash pad 8 includes a plurality of small bump crash pads 11, and the PU foam layer 4 is attached to the upper TPU film 3 and the lower TPU film 5, it will not separate under the huge impact force. The TPU film has high wear resistance and elasticity, can fix PU foam, and can also improve the service life and increase the impact resistance. The lower TPU film 5 can be designed as TPU films of various colors, generally black. After the lower TPU film 5 is formed, it has good wear resistance and improves the service life of the knee pad.

[0033] In this embodiment, the crash pad 8 is also provided with a TPU decorative ...

Embodiment 2

[0035] The production process of the integrated perfusion molding anti-collision knee pad includes the following steps:

[0036] Step 1, put the lower TPU film 5 material on the bottom layer of the bottom mold 7 tooling, the bottom mold 7 tooling is provided with a plurality of grooves, and the bottom of each groove is provided with a vacuum hole 6, through After vacuuming, the material of the lower TPU film 5 is pasted on the bottom mold 7 to form a layer of lower TPU film 5 .

[0037] Step 2, then pour the liquid PU foaming 4 material into the groove of the bottom mold 7, cover the upper layer with TPU film 3 and textile cloth, close the upper mold 1 for foaming, and the liquid PU foaming The temperature is 50-70 degrees Celsius, and the liquid PU foaming time is 10 to 15 minutes.

[0038] Step 3: After forming, press the TPU decorative strip 9 that has been cut with a decorative strip molding tool to form an integrally molded and foamed crash pad 8 . The decorative strip ...

Abstract

The present invention proposes an integral injection molding anti-collision knee pad and its production process, which includes a knee pad body and a crash pad, the crash pad is fixed on the knee pad body by sewing, and the crash pad sequentially includes a whole An integrally poured textile cloth, an upper TPU film, a PU foam layer and a lower TPU film, the crash pad includes a plurality of small bump crash pads, and the PU foam layer is bonded to the upper TPU film and the lower TPU film. Between the lower TPU film. In order to achieve a better anti-collision function and have greater impact resistance, the one-piece molding of the present invention improves the impact resistance, and the small bump anti-collision pad is combined according to the shape of the knee or related parts, which can fit Fits the knee joint for increased comfort.

Description

technical field [0001] The invention relates to the technical field of sports protectors, in particular to an integrated perfusion-molded anti-collision knee protector and a production process thereof. Background technique [0002] At present, with the development and popularization of sports and fitness, sports such as football, basketball, cycling, mountain climbing, and pulleys have attracted the participation of the general public. During sports, especially joints, some injuries will inevitably occur. Many athletes will wear knee pads. To prevent joint injuries, the knee pads currently on the market are generally knitted fabrics, or thickened at the knees, and are generally filled with foam, cotton and other materials to act as a barrier. The knees only have a certain anti-scratch and shock-absorbing effect. Can not achieve strong slowing down and dispersion impact. The impact resistance of general knee pads is proportional to the material and thickness of the filler. I...
