Cold core or inorganic core manufacturing method and cold core or inorganic core manufacturing machine

Abstract

The invention discloses a cold core or inorganic core manufacturing method and a cold core or inorganic core manufacturing machine. In the cold core or inorganic core manufacturing method, the initial position and the stop position of an upper core box is are the middle position below a core ejection rod of an air blowing / core ejection mechanism; one scheme is as follows: with a lifting type machine, a lower moving trolley drives a lower core box to a lower mold opening position, an upper moving trolley synchronously drives a sand ejection mechanism to a sand ejection position and drives the air blowing / core ejection mechanism to an air blowing / core ejection transit position; when the air blowing / core ejection mechanism ejects a core, a lifting work platform synchronously drives the lower core box to move downwards to the lower mold opening position, and a lifting mechanism delays to synchronously drive the upper core box to move downwards to the middle position; in a cold core or inorganic core manufacturing machine, a middle position space and a mold opening position are formed from top to bottom between the lower end of the core ejection rod of the air blowing / core ejection mechanism and the upper end surface of the lower core box, so that the idle loop time is saved, the equipment waste is reduced and the core manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to a core making method and a core making machine, in particular to a cold core or inorganic core making method and a core making machine. Background technique [0002] Cold core or inorganic core machine (core shooter) mainly includes: lower mobile trolley, lower core box fixed on the lower mobile trolley, upper mobile trolley, sand shooting mechanism fixed on the upper mobile trolley and blowing / core ejector Mechanism, lifting mechanism and the upper core box fixed on the lifting mechanism, for different cold core or inorganic core machine models, generally use a lifting table, through the lifting action of this mechanism to complete the core production process, we call it The workbench lift type model, or the upper part is used to press the pressing head, and the core-making production process is completed through the lifting action of this mechanism, which is called the upper pressure type model. [0003] For the above two co...

Problems solved by technology

[0006] The action of each mechanism of the existing cold core or inorganic core machine follows a single-step sequential action flow, and the sum of the running time of each action becomes the total running time of the equipment, which has a lot of empty cycle time, and cannot make full use of the cold core or Inorganic core machine reduces the efficiency of core making
