Embodiment Construction

[0008] A foundry core-making process, which is characterized in that it includes the following steps: 1) The workshop will go to the mold library to obtain qualified core boxes according to relevant procedures, and clean them after use and send them back in time. When mixing oil and sand, strictly follow the proportion Mixing, core sand and synthetic fat oil are mixed at a ratio of 100:3. In case of disputes during use, take samples and send them to the laboratory to test their strength and air permeability. When coring, the ribs of the core box must not have sand or sticky sand Phenomenon, the sand core should be evenly knocked out or knocked out of the core box on the special workbench as far as possible, and the core head should be pierced through with a Φ8mm air hole cone; Core box wear limit size;

[0009] 2) Molding sand preparation: The sand used for brake disc molding: surface sand, back sand, 3.3.1.2 The proportion of surface sand: quartz surface sand according to qua...

Abstract

The invention discloses a casting core manufacturing process. The casting core manufacturing process is characterized by comprising the following steps that (1) an operator of a workshop gets a qualified core box from a mold warehouse according to related procedures and cleans the core box and gives the core box back in time after use; (2) molding sand is prepared, specifically, sand for molding of a brake disc includes facing sand and floor sand; according to the matching of the facing sand, quartz facing sand includes quartz sand and argil at the ratio of 5:1, and pulverized coal facing sand includes quartz sand, argil and pulverized coal at the ratio of 5:1:(1-3); the granularity and strength of the facing sand need to be guaranteed during mixing, and the matching ratio needs attention during mixing of the floor sand; and (3) a cavity needs to be cleaned thoroughly before core setting. The casting core manufacturing process is simple, many repeated procedures are omitted, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a casting core making process. Background technique [0002] At present, the casting core making process is relatively complicated, and there is no unified specification and standard. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a casting core-making process, which is simple, eliminates many repetitive processes, and improves work efficiency. [0004] In order to achieve the above purpose, the present invention provides a casting core-making process, which is characterized in that it includes the following steps: 1) The workshop shall go to the mold library to obtain qualified core boxes according to relevant pro...
