Core setting equipment for integral sand core

Abstract

The invention discloses core setting equipment for an integral sand core, which comprises a lift tool frame, a first positioning device, a positioning part and a power part, wherein the first positioning device determines the preset relative position of the lift tool frame and a sand box; the positioning part is fixedly connected with the lift tool frame; the power part is arranged on the lift tool frame and used for pushing the integral sand core to close to the positioning part; and when the power part and the positioning part clamp the integral sand core together, the integral sand core is positioned in the preset core setting position. The core setting equipment has simple operation, the manual operation has smaller influence on core setting, the integral sand core has accurate positioning, and the core setting equipment can remarkably improve the core setting efficiency of the integral sand core.

Description

Technical field [0001] The present invention relates to the field of casting technology, in particular to a core setting device for integral sand cores. Background technique [0002] The molding materials used in sand casting are cheap and easy to obtain, and the molds are easy to manufacture. They are suitable for single piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production. The sand core is made of adhesive and silica sand, which has low strength and is easily damaged during operation. [0003] For some castings with complex structures and high requirements, such as complex workpieces such as bolsters and side frames in bogies, it is necessary to adopt the integral core process. The integral sand core is made by machine, and the integral sand core with complete shape and smooth surface is completed before the core is set. That is, the cavity that connects the products to each other is formed by a...

Problems solved by technology

[0007] It is not difficult to see from the above working process that the existing overall sand core spreader relies entirely on manual positioning during core setting, transportation, and lifting, and position deviation is prone to occur during the positioning process, making the overall sand core relative to the sand mold during core setting. The position of the core is not accurate enough; moreover, due to the high labor intensity of the workers, it is difficult to avoid the influence of human factors on the overall sand core positioning

[0008] In addition, the center of gravity of some integral sand cores is not on the center line, it is difficult to control the balance during the core setting process, and it is easy to damage other sand cores, which not only causes unnecessary production waste, but also affects production efficiency

[0009] Moreover, the existing core-setting equipment can only hoist one integral sand core at a time. For the process of two pieces in one box, two core-setting is required, and the production efficiency is low, which is difficult to meet the needs of rapid social development.
