Description

Technical Field

[0001] The utility model belongs to the technical field of mold cores, in particular to a quick disassembly mechanism for a core. Background Art

[0002] In the mold industry, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, the mold is a tool used to make molded objects. This tool is composed of various parts. The parts that constitute the product space are called molding parts, and the parts on the inner surface of the molded product are called cores, also known as sub-molds or back molds. The core is usually installed in a movable manner to facilitate replacement by the staff.

[0003] A Chinese patent application with publication number CN217704881U discloses a quick core replacement mechanism for a mold, including a base and a mold body arranged above the base, a notch is opened in the middle of the base and two groups of guide rods are longitudinally interspersed on the surface, an adjusting screw is arranged between the two groups of guide rods, and a sealing disk is movably arranged on the upper end of the adjusting screw, and the upper ends of the two groups of guide rods are respectively installed on both sides of the sealing disk, two groups of brackets are fixed on both sides of the mold body, and the lower ends of the two groups of brackets are connected to the base, a molding groove is opened inside the mold body, and a plurality of positioning holes are evenly opened at the bottom of the molding groove and a core body is built in, and a plurality of groups of sealing rods used in conjunction with the positioning holes are vertically fixed on the upper surface of the sealing disk. The core installation structure designed by the utility model is simple to operate and is convenient for quick installation and disassembly of the core.

[0004] Although this patent can pre-install a docking rod at the bottom of the core and cooperate with the sealing rod in the positioning hole for docking installation, the purpose of quickly installing the core can be achieved. When the core needs to be disassembled, the corresponding sealing rod below can be lifted upward to unlock the core, which is convenient for disassembly and can ensure the normal use of the mold. However, the disassembly and assembly structure used in this patent is too complicated, and the mold is often in a high temperature state. Some small parts will deform and crack after being affected by high temperature, resulting in the entire disassembly and assembly structure cannot be used normally, and regular repair and maintenance are required, which reduces the production efficiency of the mold. For this reason, we provide a core quick disassembly mechanism to solve the above problems. Utility Model Content
