DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] REFERENCE Figure 1 - Figure 3This utility model provides an embodiment of a nylon hook and loop fastener forming mold, comprising a base 1 and an upper pressure plate 2. The base 1 has multiple stamping grooves 11 on its top for accommodating the nylon material to be processed, and placement grooves 12 on both sides of the base 1 for housing the fan 62 of the cleaning component 6. To ensure precise mold alignment, guide posts 4 are provided between the four corners of the base 1 and the upper pressure plate 2. The guide posts 4 effectively guide the up-and-down movement of the upper pressure plate 2 during mold operation, preventing displacement and improving processing accuracy. A stamping die 21 is fixedly connected to the bottom of the upper pressure plate 2. This stamping die 21 is the core part for stamping and forming the nylon strip, and its bottom is slidably connected inside the stamping grooves 11. A hydraulic cylinder 3 is located at the center of the top of the upper pressure plate 2, providing the pressure required for up-and-down pressing to ensure stable mold operation during processing. Fixing components 5 are provided on both sides of the top of the base 1 to ensure that the nylon strip to be processed does not shift during stamping. To handle impurities generated during production more efficiently, a cleaning component 6 is installed inside the base 1. This cleaning component 6 can clean the surface of the nylon belt and the inside of the mold in a timely and effective manner after processing. It uses wind power to suck the impurities generated during processing out of the mold and collect them inside the collection cabinet 64, ensuring the long-term use of the mold and the cleanliness of the nylon belt.

[0033] Reference Figure 2 The fixing component 5 includes a horizontal plate 51, with sliders 52 fixedly connected to both sides of the horizontal plate 51. A spring 53 is installed at the bottom of each slider 52, with its top fixedly connected to the bottom of the slider 52 and its bottom fixedly connected to the bottom wall of a groove 55, ensuring stable movement of the slider 52 and providing some elastic cushioning. Guide plates 54 are installed on both sides of the horizontal plate 51, with their bottoms fixedly connected to the top sides of the base 1, guiding the sliders 52 to slide smoothly. Multiple grooves 55 are symmetrically formed inside the base 1, and the sliders 52 slide within the guide plates 54 and grooves 55, ensuring the stability and accuracy of the horizontal plate 51 during vertical movement. Multiple pressure-bearing columns 56 are fixedly connected to the top of the horizontal plate 51, capable of bearing and transmitting pressure during processing, ensuring uniform force distribution on the horizontal plate 51. Multiple clamping blocks 57 are fixedly connected to the bottom of the horizontal plate 51. Multiple fastening tubes are arranged side by side on the bottom of these clamping blocks 57 for better fixing of the nylon strip. The clamping blocks 57 are slidably connected inside the stamping groove 11, which can effectively fix both sides of the nylon strip to be processed when the stamping die 21 processes the nylon strip, preventing it from shifting during the processing and ensuring the accuracy and stability of the processing.

[0034] Reference Figure 2 - Figure 3The cleaning assembly 6 comprises two fans 62 and a plurality of collection cabinets 64. The two fans 62 are placed inside the placing groove 12 of the base 1, and the plurality of collection cabinets 64 are slidingly connected inside the base 1 and can be flexibly moved when needed to collect and store the impurities generated in the processing. The blast ports 61 are provided through the plurality of stamping grooves 11, which can ensure that the air flow generated by the fans 62 uniformly passes through each stamping groove 11, so that the fans 62 can effectively push the air flow and remove the residual impurities during the cleaning process. The suction ports 63 are provided on both sides of the stamping groove 11 and are through between the suction ports 63 and the collection cabinets 64, forming a complete air flow loop. When the fan 62 is started, the air enters the stamping groove 11 from the blast port 61, blows the impurities to the suction ports 63 on both sides, and the impurities are sucked into the collection cabinet 64 along with the air flow, thereby effectively cleaning the impurities in the mold and on the surface of the nylon belt.

[0035] Working principle: Place the nylon belt to be processed on the stamping groove 11, start the hydraulic cylinder 3, and the upper pressing plate 2 drives the stamping die 21 to slide into the stamping groove 11 under the action of the pressure to process the nylon belt. Before the stamping die 21 contacts the nylon belt, the bottom of the upper pressing plate 2 has contacted the pressure-receiving column 56 in the fixing assembly 5, and the pressure received is transmitted to the horizontal plate 51 below, so that the plurality of clamping blocks 57 at the bottom of the horizontal plate 51 slide downward in the stamping groove 11 to fix the nylon belt to be processed placed therein. On both sides of the horizontal plate 51, the sliding block 52 slides in the guide plate 54 and the inside of the base 1, and a certain buffer force is provided by the spring 53 arranged.

[0036] Finally, it should be noted that the above-described preferred embodiments of the present application are not intended to limit the present application, and although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
