Example Embodiment

[0025] Example 1: see Figure 1 to Figure 2 As shown, the present invention provides a cold box core making machine, which is mainly suitable for manual core production. Through a visual human-machine interaction interface, manual / automatic operation can be performed, which is very flexible and versatile; suitable for 2~ The 6-part core box mold can be equipped with multiple sets of pneumatic or hydraulic blocks to meet the needs of producing various complex sand cores. The mold loading mainly adopts manual hoisting from the front side of the equipment, and adopts a superimposed step-by-step mold loading method, and the step-by-step operation completes the loading and unloading process.

[0026] The standard model of the cold box core making machine can have different series of sand shots from 20L to 150L. The shot area can reach up to 1800mm before and after, and up to 1200mm on the left and right sides. The maximum weight of the core box can reach 7000Kg.

Abstract

The invention discloses a core machine which comprises a frame, a worktable, a worktable lifting mechanism, a lower core ejection mechanism, a lower core box moving mechanism, an upper core box lifting mechanism, a sand ejection unit and a movable air blowing cover mechanism. The core machine is characterized in that the lower core ejection mechanism is positioned in front of the worktable and is fixedly connected with the frame; the worktable lifting mechanism is of a four-guide rod structure, and lifting hydraulic cylinders are respectively arranged on two sides of the worktable; the lower core box moving mechanism comprises a driving hydraulic cylinder arranged on the worktable, a cored trolley and guide rails; the guide rails comprise a first guide rail positioned on the worktable and a second guide rail positioned on the lower core ejection mechanism; the first guide rail and the second guide rail are aligned with each other. The core machine is convenient in daily maintenance, the lower core ejection mechanism is fixed on the front side of the equipment and is not lifted along with the worktable, and the core box lifting and core taking are convenient.

Description

technical field [0001] The invention relates to a metal casting equipment, in particular to a cold box core making machine. Background technique [0002] The cold box core making machine is one of the important equipment for core sand molding in the foundry industry. Its working principle is: the core making machine drives the opening and closing of various parts of the core box, and injects the mixed core sand into the core box through compressed air. Then, the catalytic gas is introduced into the core box, and the core sand hardens in a short time to meet the process and production requirements, and is ejected from the core box. [0003] In the prior art, the main structure of the core making machine includes: the lower middle sleeve-type workbench lifting mechanism, which drives the workbench and the lower core lifting mechanism to rise and fall at the same time; the lower core box moving mechanism installed on the workbench drives the core box forward and backward. Mobi...
