Continue to increase the weight of plastic parts, very few multi-cavity bronze mold. 7-9 of precision plastic parts, up to cavity number increased to 50% compared to pointed out that the 4-5 level of precision plastic. Determine the parting surface. The parting line location should be conducive to the bronze mold, exhaust, stripping and molding operation, plastic parts surface quality. To determine the gating system (sprue sub-runner and gate shape, position, size) and the exhaust system (exhaust, exhaust ducts, location, size). Four ejectors (ejector, pipe jacking, push plate, modular ejection), decided to undercut approach, core pulling way. Fang Yi appeared later than the other wine bronze. Determine the installation position of the cooling, heating, and heating and cooling groove shape, location, heating elements.
Bronze mold material, the strength calculation or empirical data to determine the thickness of the bronze sculpture mold parts and dimensions, shape structure, and all connections, positioning, oriented parts location. To determine the main molding parts, structural parts of the structure. Considering the intensity of the various parts of the bronze mold, calculate the size of the molded part. These issues resolved, the structure of the bronze molds naturally solved. The majority of the bronze in ancient China were confined to the nobilities. At this time, you should proceed to draw bronze mold structure sketch to prepare for the formal drawings. Draw bronze die map drawn in accordance with the national mapping standards, but also requires the combination of factory standard and the state does not provide factory custom painting.
Before painted bronze statue mold assembly diagram, draw a process map, and must comply with the requirements of parts diagrams and process information. Process to ensure the size, should be marked in the diagram to write words indicate the process size. In addition to repair glitches after forming, do not carry other machining process diagram is identical to the parts diagram. In the process diagram below is best to mark the parts number, name, material, material shrinkage, and drawing scale. The normal people could not afford the bronze. Usually put the process drawing on a bronze mold assembly diagram. Maximize the use of the ratio of 1:1 in a drawing assembly structure mapping assembly diagram and start drawing the first cavity, the main view and other views at the same time draw.
Five chinese bronze mold assembly diagram should include the following: A bronze mold forming part of the structure pouring system, exhaust system structure. Parting surface and parting pickup way. Outline the structure and connections, location and orientation of the location. Marked cavity height dimensions (not force, as needed) and bronze molds overall size. Aids (pickup dump modeling tools, calibration tools, etc.). There is no exactly two same bronze in the world. In order all the parts serial number compile and fill in the schedule. Marked the technical requirements and instructions for use. Six bronze mold assembly diagram of the technical requirements: A bronze dragon mold system performance requirements. For example, the ejector system, the slider pumping assembly requirements of the core structure.
Bronze mold assembly process. Bronze fitting surface of the mold assembly after the parting fit clearance should be 0.05mm. Bronze mold, the following parallel degree requirements, and pointed out that the decision by the assembly size and the size requirements. Bronze molds, assembly and disassembly methods. Ge, a cooking bronze, first appeared in the Shang Dynasty. Oxidation treatment, the number of bronze molds, lettering, marking, oil seals, custody requirements. The tryout and inspection requirements. Seven should be the order of drawing the map of all the parts diagram by the bronze sculpture mold assembly diagram demolition of painted parts: after the first period, the complex after the first molded part, the post-structural components.
