Full-automatic wet clay sand core making machine

Abstract

The invention relates to the technical field of wet clay sand core making, in particular to a full-automatic wet clay sand core making machine which comprises a workbench, and a supporting plate is mounted on the upper surface of the workbench; a fixing plate is mounted in the center of the upper surface of the workbench; sliding rods which are uniformly distributed are fixedly mounted on one side, far away from the workbench, of the fixed plate; the sides, away from the fixed plate, of the sliding rods are jointly and slidably connected with a movable plate. A first air cylinder is fixedly mounted on the upper surface of the supporting plate; the output end of the first air cylinder penetrates through the supporting plate and is fixedly connected with the upper surface of the movable plate. Sand core boxes are mounted on the opposite sides of the movable plate and the fixed plate; the sand core box is detachably connected with the movable plate and the fixed plate through a fixing device; according to the mold release agent spraying device, the circulating pipe is arranged, a mold release agent is driven by air flow to evenly spray and cover the inner cavity of the sand core box, the redundant mold release agent is recycled through circulation of the air flow, and the applicability of the mold release agent spraying device is enhanced.

Description

technical field [0001] The invention relates to the technical field of wet clay sand core making, in particular to a fully automatic wet clay sand core making machine. Background technique [0002] Clay sand is mainly composed of original sand, clay, additives and water. During the molding process, the molding sand is formed under the action of external force and reaches a certain degree of compactness to become a sand core. Clay sand is mainly used for casting and non-ferrous metal castings. Addition of core sand to increase wet strength and improve molding properties. [0003] In the process of realizing the present invention, it is found that at least the following problems have not been solved in the prior art: [0004] 1. The existing core making machine also uses a lot of screws to fix the replacement of some particularly small sand core boxes, which is very time-consuming during disassembly and assembly. The sand core box is connected as a whole so that it cannot be...

Problems solved by technology

[0004] 1. Existing core making machines also use a lot of screws to replace some particularly small sand core boxes. It is very time-consuming to disassemble and assemble, and sometimes it is difficult to twist the screws because of the corrosion of the screws. The sand core box is connected as a whole, so it cannot be disassembled. It needs to be destroyed to disassemble the sand core box.

[0005] 2. Every time before processing the sand core, some release agent will be sprayed into the sand core box. The existing release agent spraying is often manual spraying. If the spraying is not uniform, it will easily cause a lot of waste of release agent. The operator Spraying work for a long time is prone to fatigue and reduces production capacity
