Automatic precision core assembly moulding production line, casting production line and production method thereof

Abstract

The invention discloses an automatic precision core assembly moulding production line, a casting production line and a production method thereof, wherein the core assembly moulding production line comprises an outer die core making area, an outer die core delivery line, an outer die core surface-drying furnace, a mould cavity core making area, a mould cavity delivery line, a mould cavity surface-drying furnace and a core assembly delivery line; a robot I with transportation and assembly functions is disposed on the core assembly moulding production line; the casting production line further comprises a pouring line and a robot II with a transportation function; all the sand cores used by the core assembly are produced, delivered and assembled on the core assembly moulding production line; moreover, all the actions are realized by a highly-automatic method, and robots are used for core assembly, so that the automation degree is high, the labour intensity of workers is low, the working environment is good, the production efficiency is high, the energy is saved, the consumption is decreased, the process stability is good, and the product precision is high; the sand cores used by the core assembly are shot by a cold-box core making machine; and the cast product has a high dimensional precision, a good appearance quality and a high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of casting technology, and in particular relates to a core assembly molding production line, a casting production line and a production method thereof. Background technique [0002] The current core molding casting methods for ferrous alloy castings include: core assembly by self-setting sand process and core assembly by cold core box (hot core box) process. Manufactured by hot core box technology; ②The combination of sand cores is all (or partly) realized by manual core assembly; ③The core group is poured without filling back sand, and does not form a pouring line; ④The core group passes through bolts and casings lock tight. [0003] The above-mentioned core molding casting method has the following disadvantages: ①All or part of the sand cores are made by self-setting sand technology, and the core groups are locked by sleeves and bolts, resulting in low production efficiency; ②The sand cores are combined ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned core molding casting method has the following disadvantages: ①All or part of the sand cores are made by self-setting sand technology, and the core groups are locked by sleeves and bolts, resulting in low production efficiency; ②The sand cores are combined by manual core assembly Realization, resulting in unstable core assembly accuracy, and the workers’ work intensity is high when producing larger castings; ③The core group is poured without filling the back sand, and there is a safety hazard after the molten iron runs out of fire; ④The exhaust gas of the curing agent of the core making machine is harmful to people ⑤ The non-single sand regeneration rate is low, which is not conducive to energy saving and emission reduction
