[0035] In one embodiment of the present invention, Figures 1 to 3 As shown, a disposable paper cup holder molding die is provided, comprising a power connection seat 100, an upper die seat 200 and a lower die seat 300;

[0036] The upper die base 200 is arranged opposite to the lower die base 300, the power connection base 100 is fixedly connected to the upper die base 200 and connected to an external power source, and the power connection base 100 drives the upper die base 200 to move relative to the lower die base 300;

[0037] The center of the lower mold base 300 is concave inwardly provided with a paper material placement hole 310 with an upper end surface opening, and the center of the upper mold base 200 is protruding outwardly provided with a cup holder forming column 210 adapted to the paper material placement hole 310;

[0038] In addition, the lower mold base 300 is provided with a preliminary molding guide hole 320 with an upper end surface opening, which is recessed inwardly on the right side of the paper raw material placement hole 310, and the upper mold base 200 is provided with a preliminary molding guide column 220 that is protruding outwardly on the right side of the cup holder molding column 210 and is adapted to the preliminary molding guide hole 320;

[0039] During mold closing, the paper stock is placed in the paper stock placement hole 310, the cup holder forming column 210 is inserted into the paper stock placement hole 310 to extrude the paper stock into a paper cup holder, and at the same time, the preliminary molding guide column 220 is inserted into the preliminary molding guide hole 320 to limit the mold closing process.

[0040] Specifically, in this embodiment, firstly, the disposable paper cup holder compression molding die realizes efficient and stable mold closing and opening of the upper mold base 200 and the lower mold base 300 through the precise connection of the power connection base 100 with the external power source, thereby greatly improving the production efficiency of the disposable paper cup holder. Secondly, the specially designed preliminary molding guide hole 320 and preliminary molding guide column 220 in the disposable paper cup holder compression molding die play a vital role in the compression molding process of the disposable paper cup holder. They provide precise guidance for the mold closing process, ensuring that the upper mold base 200 and the lower mold base 300 can be accurately aligned, avoiding poor molding due to misalignment. In addition, during the process of inserting the preliminary molding guide column 220 into the preliminary molding guide hole 320, the mold closing process will be limited to prevent the mold from being over-closed or under-closed, thereby ensuring that the molding size and shape of the disposable paper cup holder meet the design requirements. Finally, the cup holder forming column 210 in the upper mold base 200 is precisely matched with the paper material placement hole 310 in the lower mold base 300, ensuring the forming accuracy and consistency of the disposable paper cup holder and meeting the market demand for high-quality products.

[0041] In another embodiment of the present invention, Figures 2-3As shown, the cup holder forming column 210 and the paper stock placement hole 310 are both cylindrical structures, and the upper circle diameter of the cup holder forming column 210 and the paper stock placement hole 310 is larger than the lower circle diameter, and thus the outer wall of the cup holder forming column 210 and the inner wall of the paper stock placement hole 310 are both conical surfaces with a larger upper part and a smaller lower part.

[0042] Specifically, in this embodiment, the conical surface structure formed by the cup holder forming column 210 and the paper stock placement hole 310 also makes the stress distribution of the paper stock during the forming process more uniform. Since the upper circle diameter of the cup holder forming column 210 and the paper stock placement hole 310 is larger than the lower circle diameter, the paper stock can gradually adapt to the changes in the conical surface when being squeezed, avoiding the deformation or cracking of the disposable paper cup holder due to stress concentration. This design improves the strength and durability of the disposable paper cup holder, making it more reliable during use.

[0043] In another embodiment of the present invention, Figures 2-3 As shown, the outer wall of the cup holder forming column 210 is provided with multiple groups of outer forming pattern groups 400 at intervals along its height direction, and the inner wall of the paper stock placement hole 310 is provided with multiple groups of inner forming pattern groups 500 at intervals along its height direction; when the cup holder forming column 210 is fully inserted into the paper stock placement hole 310, the multiple groups of outer forming pattern groups 400 correspond to the multiple groups of inner forming pattern groups 500 one by one and are located at the same height.

[0044] Specifically, in the present embodiment, in the disposable paper cup holder molding die, the design of the outer molding pattern group 400 and the inner molding pattern group 500 provided on the cup holder molding column 210 and the paper stock placement hole 310 greatly enhances the molding effect and aesthetics of the disposable paper cup holder. When the cup holder molding column 210 is fully inserted into the paper stock placement hole 310, the multiple groups of outer molding pattern groups 400 correspond to the multiple groups of inner molding pattern groups 500 one by one and are located at the same height. These pattern groups will act on the paper stock at the same time during the molding process to form fine patterns and patterns. This not only improves the appearance quality of the disposable paper cup holder, but also increases its anti-slip property and durability, making the disposable paper cup holder more stable and safe during use.

[0045] In another embodiment of the present invention, Figures 4-5 As shown, each group of the outer molding pattern groups 400 includes multiple circles of outer molding convex patterns 410 spaced apart along the height direction of the cup holder molding column 210, and each group of the inner molding pattern groups 500 includes multiple circles of inner molding grooves 510 spaced apart along the height direction of the paper stock placement hole 310; when the cup holder molding column 210 is fully inserted into the paper stock placement hole 310, the multiple circles of the outer molding convex patterns 410 correspond to the multiple circles of the inner molding grooves 510 one by one and are located at the same height.

[0046] Specifically, in this embodiment, from the perspective of production efficiency and cost, the design of multiple circles of outer molding convex patterns 410 and inner molding grooves 510 optimizes the molding process of the disposable paper cup holder. Since the paper raw material can be gradually subjected to pressure during the molding process, deformation or cracking caused by excessive compression at one time is avoided, thereby improving production efficiency, reducing scrap rate, and further reducing production costs.

[0047] In another embodiment of the present invention, the cross-sectional shapes of the outer molding convex pattern 410 and the inner molding groove 510 are semicircular or V-shaped.

[0048] Specifically, in this embodiment, the semicircular or V-shaped cross-sectional shape enables the outer molding convex pattern 410 and the inner molding groove 510 to more effectively contact and apply pressure to the paper stock during the molding process. This shape can ensure that the paper stock is evenly stressed during molding, thereby improving the molding effect of the disposable paper cup holder, making its shape more regular and its size more precise.

[0049] In another embodiment of the present invention, Figure 3 As shown, the paper stock placement hole 310 is vertically arranged and extends from the upper surface of the lower mold base 300 along the height direction of the lower mold base 300, and the cup holder forming column 210 is vertically arranged and extends from the lower surface of the upper mold base 200 along the height direction of the upper mold base 200.

[0050] Specifically, in this embodiment, the vertical arrangement of the paper stock placement hole 310 and the cup holder forming column 210 ensures the alignment accuracy of the upper mold base 200 and the lower mold base 300 during the molding process. This design allows the paper stock to be evenly stressed during molding, thereby improving the molding accuracy of the disposable paper cup holder and ensuring that the size and shape of the disposable paper cup holder meet the design requirements.

[0051] In another embodiment of the present invention, Figure 3 As shown, the preliminary molding guide hole 320 is vertically arranged and extends from the upper surface of the lower mold base 300 along the height direction of the lower mold base 300, and the preliminary molding guide column 220 is vertically arranged and extends from the lower surface of the upper mold base 200 along the height direction of the upper mold base 200.

[0052] Specifically, in this embodiment, the vertical design of the preliminary molding guide hole 320 and the preliminary molding guide column 220 makes the opening and closing process of the disposable paper cup holder molding die easier. The operator only needs to align the preliminary molding guide column 220 with the preliminary molding guide hole 320 and press down to complete the alignment, without complicated adjustment steps, thereby simplifying the operation process and improving production efficiency.

[0053] In another embodiment of the present invention, Figures 1-2 As shown, the upper surface of the power connection seat 100 is recessed outward and is provided with a power source connection hole 110 for connecting to an external power source.

[0054] Specifically, in this embodiment, the design of the power source connection hole 110 enables the external power source to be stably connected to the power connection seat 100. The recessed power source connection hole 110 structure can ensure that the connection piece fits tightly, reduces shaking and misalignment, and thus ensures the stability and reliability of the disposable paper cup holder molding die during the molding process.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
