Core unloading device of sand core assembly

Abstract

The invention relates to a core unloading device of sand core assembly; and the core unloading device is used for assembling and clamping a combined sand core to achieve subsequent lifting by using a trolley. The core unloading device comprises a sand core moving unit positioned at the upper end; the sand core moving unit comprises a sanding core moving bracket; a clamping mechanism for clamping the sand core is mounted on the sand core moving bracket; a sand core fixing unit is positioned at the lower end, and comprises a sand core fixing bracket; a core assembly worktable is mounted on the sand core fixing bracket; and a sand core bracket is movably supported on the core assembly worktable. The core unloading device has the following advantages: firstly, the sand core is preassembled on the core assembly worktable; then, the assembled sand core is clamped by using the clamping mechanism; finally, the trolley is used for shifting the sand core moving bracket and the clamped sand core to a machining place; and by dint of mechanical clamping and movement, such bad conditions as unstable core unloading and sand scratch caused by hot working sand unloading can be effectively prevented, and casting wastes are reduced.

Description

Technical field [0001] The invention relates to the field of casting production, in particular to a core lowering device for assembling sand cores. Background technique [0002] With the continuous development of science and technology, people's production and life have been greatly facilitated. Among them, casting is a metal thermal processing technology that humans have grasped relatively early. Casting is a method of pouring liquid metal into a casting cavity suitable for the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The cast material is mostly metal that is originally solid but heated to a liquid state, and the material of the mold can be sand, metal or even ceramics. [0003] At present, in the casting production process, the sand core structure used varies according to the complexity of the product to be cast, and multiple sand cores are often assembled from multiple directions to form the entire sand core structure. For this k...

AI Technical Summary

Problems solved by technology

For this kind of sand core structure, there are the following disadvantages in the process of setting the core: it is easy to cause loose clamping and loose positioning, and because the weight of the assembled sand core is heavy, the manual handling of the core is unstable, which is easy to cause Sanding the core, resulting in casting waste and increasing production costs
