Embodiment

[0027] Referring to the figure, please refer to Figures 1-5 , which is the first embodiment of the present utility model. This embodiment provides a bottle cap compression molding die, including an upper pressing block 1, and a lower pressing block 2 is arranged below the upper pressing block 1; further including:

[0028] A fixing mechanism 3, which is respectively arranged at the bottom of the upper pressing block 1 and the top of the lower pressing block 2 for fixing the die;

[0029] A buffer mechanism 4, which is arranged at the four corners of the bottom of the upper pressing block 1.

[0030] Specifically, the fixing mechanism 3 respectively includes a lower sliding groove 301 opened at the bottom of the upper pressing block 1 and an upper sliding groove 302 opened at the top of the lower pressing block 2, and threaded holes 303 are opened on the inner walls of the lower sliding groove 301 and the upper sliding groove 302.

[0031] Furthermore, the upper pressing block 1 and the lower pressing block 2 provide the pressure and enclosed space required for compression molding, ensuring that the plastic is molded into a bottle cap in the mold. Through the cooperation of the upper and lower pressing blocks, the compression molding of the bottle cap is completed, ensuring the shape, size, and precision of the bottle cap. The fixing mechanism 3 ensures the stability and positioning accuracy of the convex mold 5 and the concave mold 6 during the compression molding process, preventing the mold from shifting or shaking during the compression molding process, and is convenient to adjust to accommodate molds of different sizes and shapes.

[0032] Specifically, the convex mold 5 and the concave mold 6 are respectively slidably installed inside the lower sliding groove 301 and the upper sliding groove 302. The convex mold 5 and the concave mold 6 are both fixed in the sliding groove by bolts. The fixing mechanism 3 further includes a limiting block 304 inserted at the ends of the lower sliding groove 301 and the upper sliding groove 302. The limiting block 304 is respectively fixed and installed on the sides of the upper pressing block 1 and the lower pressing block 2 by bolts.

[0033] Furthermore, the lower sliding groove 301 is used for slidably installing the convex mold 5, the upper sliding groove 302 is used for slidably installing the concave mold 6, threaded holes 303 are respectively opened on the inner walls of the lower sliding groove 301 and the upper sliding groove 302 for fixing the convex mold 5 and the concave mold 6 in the sliding groove by bolts, and the limiting block 304 is used to prevent the convex mold 5 and the concave mold 6 from sliding out during the compression molding process.

[0034] Specifically, guide rods 7 are fixedly installed at the four corners of the bottom of the upper pressing block 1, and guide grooves 8 are respectively opened at the four corners of the top of the lower pressing block 2.

[0035] Furthermore, the guide rods 7 slide in the guide grooves 8 to ensure the stable movement of the upper pressing block 1 during the compression molding process, provide guidance and support for the upper pressing block 1, and ensure its stability and accuracy during the compression molding process.

[0036] Specifically, the buffer mechanism 4 includes a buffer spring 401 sleeved outside the guide rod 7 and a pressure ring 402. The pressure ring 402 is located below the buffer spring 401, and the top of the buffer spring 401 is connected to the upper pressing block 1.

[0037] Furthermore, the buffer mechanism 4 provides buffering during the compression molding process, avoids sudden impact of the upper pressing block 1 on the lower pressing block 2, protects the mold and the compression molding machine, reduces the wear of the mold and the compression molding machine, extends the service life, and improves production stability. When the upper pressing block 1 moves downward, the pressure ring 402 compresses the buffer spring 401, thereby playing a buffering role.

[0038] Specifically, coolant inlets and outlets 9 are respectively opened on the sides of the upper pressing block 1 and the lower pressing block 2, and coolant circulation pipelines are arranged inside the upper pressing block 1 and the lower pressing block 2.

[0039] Furthermore, the coolant enters the circulation pipeline through the coolant inlets and outlets 9 to cool the mold, maintain the appropriate temperature of the mold during the compression molding process, and prevent the mold from deforming or being damaged due to overheating.

[0040] Working principle:

[0041] During use, first, the convex mold 5 and the concave mold 6 are respectively slidably installed into the lower chute 301 and the upper chute 302, and fixed in the threaded holes 303 by bolts. Then, the limit blocks 304 are fixed to the sides of the upper pressing block 1 and the lower pressing block 2 by bolts to prevent the molds from sliding out during the compression molding process. Next, start the compression molding machine. The upper pressing block 1 moves downward under the drive of the compression molding machine, and the guide rod 7 slides in the guide groove 8 to ensure the stable movement of the upper pressing block 1. When the convex mold 5 contacts the concave mold 6, the compression molding of the bottle cap begins. During the compression molding process, the buffer spring 401 plays a buffering role to avoid mold damage or product defects caused by sudden impacts. At the same time, the coolant circulation pipeline connected through the coolant inlet and outlet 9 continuously circulates the coolant to maintain the appropriate temperature of the mold during the compression molding process, ensuring the quality and molding effect of the bottle cap. After the compression molding is completed, the upper pressing block 1 moves upward under the drive of the compression molding machine, separates from the concave mold 6, and the formed bottle cap is taken out, completing a complete compression molding cycle. When it is necessary to replace the mold to adapt to the production of bottle caps of different specifications, use tools to remove the bolts fixing the convex mold 5, the concave mold 6, and the limit blocks 304, and sequentially remove the limit blocks 304, the convex mold 5, and the concave mold 6 from the chute. Next, install the new specification mold into the lower chute 301 and the upper chute 302 according to the same steps and fix it with bolts to ensure the tight fit between the mold and the chute.

[0042] In summary: Through the fixing mechanism 3 provided at the bottom of the upper pressing block 1 and the top of the lower pressing block 2, the stability and positioning accuracy of the convex mold 5 and the concave mold 6 during the compression molding process are ensured. Among them, the ingenious design of the lower chute 301 and the upper chute 302, combined with the fastening effect of the threaded holes 303 and bolts, not only makes the fixing of the mold firm and easy to adjust to meet the requirements of molds of different sizes and shapes. In addition, by using the lower chute 301 and the upper chute 302 in combination with bolts, the convex mold 5 and the concave mold 6 can be easily removed from and installed in the mold, thus significantly reducing the time and labor costs for mold replacement and further improving the production efficiency.
