Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the existing technical defects, provide an impact-resistant mold and its manufacturing method, and solve the problem that the impact resistance of the mold produced in the prior art is not enough, which leads to the impact of other molds in the casting production process in the later stage. When casting equipment is knocked, collided or impacted by other external forces, the mold is often damaged and the service life is low. In production, once the mold is damaged, if it cannot be replaced in time, it will affect the production progress and cause low production efficiency. The mold has improved durability. Impact ability prolongs the service life, improves the production efficiency and production quality of castings, and greatly improves the economic benefits of the enterprise

Abstract

The invention discloses an anti-impact mold and a manufacturing method thereof, and relates to the technical field of castings. The mold comprises 18-25% of attapulgite clay, 35-40% of limestone sand, 30-35% of coal gangue, 3-5% of one or more adhesives and 3-5% of a reinforcing agent, and is manufactured through the following processes: crushing and screening; heating and baking; cooling; mixing; blank forming and sintering; and cooling molding. By adoption of the manufacturing method, the technical defects in the prior art can be overcome, that is, the problems that due to the poor anti-impact performance, a mold manufactured in the prior art is always damaged and low in service life when being stricken by or collided with other casting equipment and impacted by other external forces in a casting production process at the later stage, and once the mold is damaged and cannot be replaced in time during the casting production, the production progress is influenced and the production efficiency becomes low can be solved; the anti-impact capability and the service life of the mold provided by the invention are improved and prolonged respectively; the casting production efficiency and production quality are improved; and the enterprise economic benefit is greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of castings, in particular to an impact-resistant mold and a manufacturing method thereof. Background technique: [0002] In the production of castings, the quality of the mold directly affects the quality of the later castings. Due to the formula and process problems in the traditional mold production, the impact resistance of the produced molds is not enough, which leads to the impact of other casting equipment during the later casting production process. Knocking, collision and other external impacts often cause damage to the mold, and the service life is low. In production, once the mold is damaged, if it cannot be replaced in time, it will affect the production progress and cause low production efficiency. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the existing technical defects, provide an impact-resistant mold and its manufacturing method,...
