Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0029] like figure 2 As shown, the present invention discloses a flexible nozzle head of a core making machine, which includes a housing, the housing includes an integrally connected arc-shaped nozzle head 1 and a connecting body, and a conical hole 6 and a straight hole communicating with each other are opened in the housing 7. The tapered hole 6 is opened in the connection body; the connection body includes the splint section 2, the sipe section 3, the extended thread section 4 and the extension section 5 connected in sequence, and the diameters of the extension section 5 and the sipe section 3 are smaller than the extension thread The diameter of the section 4, the diameter of the lengthened threaded section 4 is less than the diameter of the clamping plate section 2; the whole shell is m...

Abstract

The invention relates to the technical field of core making machines, and discloses a flexible nozzle head of a core making machine. The flexible nozzle head comprises a shell, the shell comprises an arc-shaped nozzle head and a connecting body which are integrally connected, a conical hole and a straight hole which are communicated with each other are arranged in the shell, and the conical hole is arranged in the connecting body; the connecting body comprises a clamping plate section, a cutter groove section, a lengthened thread section and an extension section which are connected in sequence, the diameters of the extension section and the cutter groove section are smaller than the diameter of the lengthened thread section, and the diameter of the lengthened thread section is smaller than the diameter of the clamping plate section; and the shell is made of wear-resistant and temperature-resistant plastic. The nozzle has certain flexibility, so that when the flexible nozzle head is combined with the mold, the nozzle head can be automatically closed by utilizing the pressure between the flexible nozzle head and the mold, a dislocation gap caused by clamping the mold is solved, the damage of the nozzle head and the damage of the mold caused by material leakage are avoided, the effect of quickly positioning the mold and the nozzle head is achieved, the butt joint time of the mold and the flexible nozzle head is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of core making machines, in particular to a flexible nozzle head of a core making machine and a method for installing it with a mold. Background technique [0002] At present, the core-making machines on the market all use steel nozzle heads, and the radius of the ball head is small (R5~R8mm), the thread section is short, the sealing area of ​​the slurry is small, and it cannot undertake high-pressure pressing. The pressure is very high, the maximum can reach 7MP. During the pressing process, due to the imperfect match between the mold and the core making machine, there will be a certain gap between the nozzle head and the mold material bowl. Under high pressure, the slurry will follow the gap Extrusion leakage will not only fail to form qualified ceramic core blank parts, but also easily wear the mold inlet and nozzle head, resulting in damage to the nozzle head. In severe cases, it will damage the mold inl...
