Description

Technical Field

[0001] The utility model relates to a mold, in particular to a floating mold frame. Background Art

[0002] Molds are important process equipment in industrial production and can be roughly divided into two parts: the core and the mold base. Some working parts in the mold are in direct contact with the molded product. For example, the punch and die of a hardware mold directly contact the metal plate being processed, and the core and cavity of a plastic mold directly contact the finished plastic part. These working parts are called "cores." The assembly of parts used to mount the mold's working parts (cores) and other structural parts, ensure the mold's working parts are in the correct relative position during operation, and connect the mold to the machine tool is called the "mold base."

[0003] A mold frame is typically constructed from a stack of several plate-like components, each secured together by fasteners. Using conventional commercially available fasteners, due to the structural, positional, and movement relationships between the various plate-like components, requires staggering the installation positions of the various fasteners to prevent interference. This arrangement requires a large number of fastener connection holes in the plate-like components, significantly increasing mold frame production costs and reducing strength. Utility Model Content

[0006] By adopting this technical solution, the connecting assembly connecting the movable forming plate and the mold base is connected through the fourth connecting hole formed in the first fastener. This arrangement eliminates the need for separate holes in the mold base and the backing plate, reducing the number of holes and the number of hole-making steps, thereby lowering mold frame production costs and improving mold frame strength. Furthermore, this arrangement integrates the connecting assembly and the first fastener, making the mold frame more compact and simpler in appearance, and also facilitating subsequent maintenance.

[0007] It is further configured that: the first fastener is threadedly connected to the first connecting hole and the second connecting hole, and the fourth connecting hole cooperates with the connecting assembly to limit the rotation of the first fastener.

[0008] By adopting the above technical solution, the connecting assembly cooperates with the fourth connecting hole to limit the rotation of the first fastener to avoid the loosening of the installed first fastener due to vibration during use, thereby improving the stability of the connecting structure.

[0009] It is further configured as follows: a plurality of fifth connecting holes corresponding one-to-one to the third connecting holes are provided on the movable forming plate, and a plurality of groups of the connecting components are arranged one-to-one corresponding to the fifth connecting holes, and the connecting components include a connecting screw that passes through the fifth connecting hole, the third connecting hole and the fourth connecting hole in sequence and extends to the bottom of the fourth connecting hole, and a connecting nut that is threadedly connected to the connecting screw and is located below the fourth connecting hole.

[0010] By adopting the above technical solution, the connecting screw and the connecting nut cooperate to restrict the movable forming plate from separating from the mold base, thereby realizing the connection limiting function.

[0011] It is further configured as follows: the fifth connecting hole limits the rotation of the connecting screw, a limiting component for limiting the rotation of the connecting nut is provided in the first connecting hole, and the limiting component has a limiting state and a non-limiting state.

[0013] It is further configured as follows: the connecting screw includes a limiting section and a threaded section threadedly connected to the connecting nut, and the limiting section cooperates with the fourth connecting hole to form a rotation limit.

[0014] By adopting the above technical solution, the setting of the limiting section cooperates with the fourth connecting hole to limit the first fastener.

[0015] It is further configured that: the limiting assembly includes a limiting frame located on one side of the connecting nut and reciprocating toward the connecting nut, and a pressing spring driving the limiting frame to cooperate with the connecting nut to form a limit.

[0016] By adopting the above technical solution, the spring is tightened to drive the limit frame to press against the connecting nut, thereby limiting the rotation of the connecting nut to form a limit.
