Process method for rapidly developing cast product sample

Abstract

The invention discloses a process method for rapidly developing a cast product sample, belongs to the technical field of casting. The technical scheme in the invention is as follows: 1. using a plurality of general devices to manufacture resin sand or coated sand billet similar with cast product specification; 2. making a model inversion on a model sand billet, processing a core sand billet as a required sand core; 3. for the cast product sample with complex structure and shape, using a method for processing the cast product sample with complex structure and shape as the model inversion and the sand core on a numerical control machine such as a machining centre or a carved milling machine; 4. coating the processed model inversion and sand core with bad surface quality by using alcohol-based or water-based paint until meeting the demand; 5. making a pouring and feeding system, combining the model inversion and sand core, pouring to obtain a corresponding cast product sample. The process method effectively shortens the manufacturing period of the product sample and core box, reduces the product development input as much as possible at an early stage, and lays foundation for manufacturing a permanent metal model and core box in the next step.

Description

technical field [0001] The invention relates to a process method for quickly developing casting product samples, which belongs to the technical field of casting. Background technique [0002] At present, the development of casting products generally needs to go through the steps of drawing review-process design and confirmation-pattern and core box design and confirmation-master mold making-returning pattern and core box blanks-processing mold and core box-trial production or trimming-putting into production and other steps , Usually the cycle is very long, mainly focusing on the design and production of the entire mold and core box, especially the production process. In the current highly competitive market environment, the time for customers to provide samples is getting shorter and shorter. Some foreign customers provide drawings today and wish to provide samples tomorrow, and they will be constantly urged by phone, email, and fax. At the same time, there are generally c...
