Core assembling tool for casting and core assembling method of casting mould

Abstract

The invention relates to a core assembling tool for casting and a core assembling method for a casting mould in the technical field of casting. The core assembling tool for casting comprises two rows of guide rails which are arranged in parallel; a plurality of reinforcing plates are vertically arranged between the guide rails; a fixing end plate is vertically arranged at one ends of the guide rails, and stop blocks protruding out of the surfaces of the guide rails are fixedly arranged at the other ends of the guide rails; a hanger shaft perpendicular to the guide rails is arranged at each of the positions, 1 / 5-1 / 4 of the total length of the guide rails, at the two ends of the bottom sides of the guide rails; a plurality of supporting plates are arranged on the upper sides of the guide rails in a sliding manner and are used for bearing assembled type casting moulds; two rows of sliding block guide rails matched with the guide rails are fixedly arranged at the bottoms of the supporting plates; a movable end plate is arranged in the position, close to one ends of the stop blocks, on the guide rails; guide grooves matched with the guide rails in shapes are formed in the bottom of the movable end plate; auxiliary sliding blocks matched with the guide rails are fixedly arranged on the outer side of the movable end plate; a plurality of pull rods are arranged between the fixing end plate and the movable end plate and used for tensioning and clamping assembled casting moulds.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a core assembly tool for casting and a core assembly method for a mold. Background technique [0002] The core assembly problem is often involved in the casting process. It is typical to pour the core directly after assembly, such as the core assembly process. However, limited by the clamping tooling, this process is only suitable for the production of some small and medium-sized castings. The core is small in size and clamped by a screw and a U-shaped plate. However, this kind of core assembly tooling can only meet the situation where the number of cores is small. When the number of cores is large, due to the action of friction of the cores, the gap between the cores is large due to the small force when the middle core is clamped. It can only be solved by vertical core assembly. However, it is necessary to turn the assembled core 90° before pouring. This method is cumbersome t...

Problems solved by technology

[0003] (1) High cost of mold manufacturing

[0004] (2) The ratio of sand to iron is large, and the casting cost is high

[0005] (3) A large amount of sand is eaten around the casting, slow cooling, long production cycle and low efficiency
