[0003] However, the mold base of the motorcycle guard plate molding mold is relatively complex and the development cost is relatively high. Summary of the invention

[0004] The utility model aims to provide a motorcycle guard plate forming die, the design of the die frame of the die provides secondary mold opening conditions for product demoulding, the die frame has a simple structure, is easy to assemble, and has low development cost.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a motorcycle guard plate forming mold, including a mold frame, the mold frame includes an upper mold plate, an upper mold frame and a lower mold frame that are overlapped and connected in sequence from top to bottom, and also includes a lower mold plate located below the lower mold frame, a mold foot for supporting the lower mold frame is provided between the lower mold frame and the lower mold plate, a movable top plate is provided on the lower mold plate, a movement space for the top plate to move up and down is provided between the lower mold frame and the lower mold plate, an activity space is provided between the upper mold plate and the upper mold frame, a limiting plate is provided in the activity space, the limiting plate is movably connected to the upper mold frame, the upper mold plate is connected to the upper mold frame and the two are linked, and the upper mold plate and the limiting plate are transmission-connected through a limiting structure; the upper mold frame is provided with an upper mold core, and the lower mold frame is provided with a lower mold core; the upper mold core and the lower mold core are molded together to form a product molding gap; a first water transport structure is provided in the upper mold frame; and a second water transport structure is provided in the lower mold frame.

[0006] The upper template is fixedly connected to the upper mold frame by bolts. During the first mold opening, the upper template moves upward with the upper mold frame until the upper mold frame abuts against the limit plate for the second mold opening. The upper template pulls the limit plate through the limit structure and moves upward synchronously with the upper mold frame.

[0007] Compared with the prior art, the utility model has the advantages that the design of the mold frame of the mold provides secondary mold opening conditions for product demoulding, provides basic conditions for the subsequent secondary mold opening design of the mold, and thus ensures that the product can be demoulded smoothly. The movable connection between the limit plate and the upper mold frame and the transmission connection mechanism with the upper mold plate further enhance the controllability and flexibility of the demoulding operation. The mold frame structure is simple and intuitive, which is not only easy to assemble and maintain, but also reduces complex mechanical parts, thereby greatly reducing the development and manufacturing costs of the mold. The support design between the lower mold frame and the lower mold plate with mold feet, as well as the movable top plate on the lower mold plate, not only provides a stable support frame for the mold, but also ensures the stability of the mold under the molding pressure and the molding accuracy of the product, and extends the service life of the mold. The first water transport structure and the second water transport structure respectively arranged in the upper mold frame and the lower mold frame effectively improve the cooling efficiency of the mold, ensure temperature control during the molding process, avoid product deformation or defects caused by local overheating, and improve the quality of the finished product. The molding gap formed by the precise cooperation between the upper die and the lower die, combined with the efficient cooling system, can not only ensure the dimensional accuracy of the molded product, but also improve the surface finish of the product to meet the production needs of high-quality motorcycle guards.

[0008] In some embodiments of the utility model, a guide rod is provided between the limit plate and the lower mold frame, the upper end of the guide rod is fixedly connected to the limit plate, the lower end of the guide rod is movably cooperated with the lower mold frame, and the guide rod passes through the upper mold frame.

The upper and lower ends of the guide rod are respectively coordinated with the limit plate and the lower mold frame, and run through the design of the upper mold frame, which not only ensures the flexible interaction between the various components, but also maintains the overall structural strength of the mold.

[0010] In some embodiments of the utility model, there is a travel space between the limit plate and the upper mold frame for the upper mold frame to move. In this embodiment, a travel space is designed between the limit plate and the upper mold frame to provide a necessary range of movement for the upper mold frame to move upward, which not only ensures that the limit plate can fully respond to the pulling action of the upper mold plate to complete the secondary mold opening, but also facilitates the adjustment and control of the mold opening stroke, thereby improving the operational flexibility and adaptability of the mold.

[0011] In some embodiments of the utility model, the lower mold frame is provided with a positioning hole that cooperates with the lower end of the guide rod. The positioning hole specially provided in the lower mold frame cooperates with the lower end of the guide rod to achieve accurate positioning of the guide rod in the lower mold frame, enhance the position stability between the mold components, prevent deviation under molding pressure, and thus ensure the dimensional accuracy and consistency of the molded product.

[0012] In some embodiments of the utility model, the upper mold frame is provided with a guide channel matched with the guide rod, and a shaft sleeve is provided in the guide channel, and the shaft sleeve is sleeved with the guide rod. The guide channel and the shaft sleeve provided in the upper mold frame are closely matched with the guide rod, which not only further optimizes the smoothness and wear resistance of the guide system, but also reduces the movement resistance and prolongs the service life of the mold. The use of the shaft sleeve effectively reduces the wear of the guide rod during the movement process, and ensures the reliability and stability of the long-term operation of the mold.

[0013] In some embodiments of the utility model, the limiting structure includes a pull rod and a limiting block, the limiting block is fixedly connected to the limiting plate, the pull rod is fixedly connected to the upper template, the pull rod includes a slide portion and a supporting portion, the slide portion is movably matched with the limiting block, the supporting portion is located below the slide portion, and the supporting portion cooperates with the limiting block to keep the limiting plate and the upper template in linkage. Through the ingenious design of the pull rod and the limiting block, the upper template can effectively control the limiting plate. This linkage mechanism makes the movement of the limiting plate closely synchronized with the mold opening action of the upper template, thereby improving the controllability and efficiency of the demolding operation. The matching design of the slide portion and the supporting portion ensures the stable guidance and reliable linkage relationship of the limiting plate during the movement.

[0014] In some embodiments of the utility model, the limiting structure further includes a positioning block, the positioning block is fixedly connected to the lower mold frame, a positioning sleeve hole is provided in the positioning block, and the pull rod is movably fitted in the positioning sleeve hole. The positioning block ensures the correct position and movement trajectory of the pull rod in the mold, and enhances the stability of the entire limiting structure.
