Description

Technical Field

[0001] The utility model relates to the technical field of mold cores, in particular to a mold core with a positioning and installation structure. Background Art

[0002] The mold core, as the name implies, refers to a precision part used for key operations in the center of the mold. In the manufacturing industry, 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. From the appearance of the product mold, the raised part is the core, and the concave part is the cavity. The core and cavity appear in pairs. The cavity and core of the mold are combined to form the space that is the shape of the mold product. Mold cores are often used in the production of automotive equipment, semiconductors and other products.

[0003] The existing mold core is used by placing the mold core in a mold core seat of a positioning and mounting structure, and connecting and fixing the mold core seat and the mold core by bolts. Since the mold core is fixed by a single bolt and a core seat, the mold core seat can only install a single model of mold core, so the scope of application is narrow and the use is inconvenient. Utility Model Content

[0004] The utility model aims to provide a mold core with a positioning and installation structure to solve the problem raised by the above background technology that the mold core seat on the market can only install a single model of mold core.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold core with a positioning and mounting structure, comprising a mold core body and a fixing frame, the outer wall of the top end of the mold core body is sleeved with a fixing frame, the outer wall of the mold core body is located inside the fixing frame and is sleeved with a supporting ring, the outer wall of the mold core body is located above the supporting ring and is sleeved with a mounting ring, four groups of threaded rods passing through the mounting rings are welded to the top end of the support ring, and the outer walls of the top ends of the four groups of threaded rods are sleeved with nuts.

[0006] Preferably, the outer wall of the threaded rod is threadedly connected to the inner wall of the nut.

[0007] Preferably, a limiting groove is provided on the outer wall of the mounting ring, and a fixing bolt extending into the limiting groove is provided inside the fixing frame.

[0008] Preferably, the fixing bolt is threadedly connected to the fixing frame, and one end of the fixing bolt is engaged with the inside of the limiting groove.

[0009] Preferably, a spring is sleeved on the outer wall of the mold core body at the bottom end of the support ring.

[0010] Preferably, the outer wall of the support ring is slidably connected to the inner wall of the fixing frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When installing the mold core, the support ring and the mounting ring are sleeved on the outer wall of the mold core body, and the mounting ring and the support ring are connected by a threaded rod and a nut. The position of the mounting ring is adjusted by adjusting the height of the nut, so that the distance between the mounting ring and the support ring can be adjusted, and the mold core body is fixed by the mounting ring and the support ring, and the fixing frame and the mounting ring are fixed by the limit groove and the fixing bolt, so that different types of mold cores can be positioned and installed, which is convenient for replacing and using different types of mold cores, providing convenience for production use.

[0013] 2. When the mold core and the positioning installation structure need to be disassembled, the fixing bolts and the fixing frame are spirally disassembled by using an external hexagonal wrench. The spring pushes the support ring to rise under the influence of the elastic force. The rising support ring drives the threaded rod, nut, mounting ring and mold core body to rise, so that the mold core body and the fixing frame are separated, making it easy to quickly disassemble and repair the mold core and the positioning installation structure.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The utility model provides a technical solution: a mold core with a positioning and mounting structure, comprising a mold core body 1 and a fixing frame 2, the outer wall of the top end of the mold core body 1 is sleeved with the fixing frame 2, the outer wall of the mold core body 1 is located inside the fixing frame 2 and is sleeved with a supporting ring 3, the outer wall of the mold core body 1 is located above the supporting ring 3 and is sleeved with a mounting ring 4, four groups of threaded rods 301 penetrating the mounting ring 4 are welded to the top end of the supporting ring 3, and nuts 302 are sleeved on the outer walls of the top ends of the four groups of threaded rods 301.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the outer wall of the threaded rod 301 is threadedly connected to the inner wall of the nut 302 .

[0022] During specific implementation, when it is necessary to install different types of cores, the operator will sleeve the support ring 3 from the bottom end of the core body 1 upwards, and sleeve the mounting ring 4 from the top end of the core body 1 downwards, the mounting ring 4 is sleeved on the outer wall of the threaded rod 301, and the nut 302 is screwed to the threaded rod 301, and the position of the mounting ring 4 is adjusted by adjusting the height of the nut 302, so that the distance between the mounting ring 4 and the support ring 3 can be adjusted, and the core body 1 is fixed by the mounting ring 4 and the support ring 3, and then the fixing frame 2 is sleeved on the outer walls of the support ring 3 and the mounting ring 4, and the fixing frame 2 is fixed to the mounting ring 4 by the limiting groove 401 and the fixing bolt 402, so that different types of cores can be positioned and installed, which is convenient for replacing and using different types of cores, providing convenience for production use.
