Embodiment 1
[0019] Embodiment 1: a metal component casting process, it comprises the steps:
[0020] (1) Manufacture pattern: After polishing the finalized metal components or the newly produced product model, wipe the surface with pure cotton cloth, and then apply Vaseline evenly on the surface;
[0021] (2) Silicone outer mold: a silicone rubber mold made of silicone rubber by multi-layer smearing or three-dimensional pouring with a pouring port reserved, and gypsum is used as a foil mold for the outside.
[0022] (3) Wax mold making: Melt the paraffin, pour it into the silicone mold through the sprue, and form a hollow paraffin mold after cooling;
[0023] (4) Modeling: a. Pour plaster into the inner cavity of the hollow paraffin wax model, and perform surface finishing after the inner cavity gypsum solidifies to make a solid paraffin wax model; b. According to the shape of the solid paraffin wax model, weld the pouring port and the solid paraffin wax model Riser system, and then atta...
Embodiment 2
[0027] A metal component casting process, which includes the process steps described in embodiment 1, wherein, in the step (2), external resin is used as a lining mold; the resin quartz sand is the resin quartz sand used in summer. The weight ratio is: 120 Obtain 100 parts of quartz sand, 1.6 parts of epoxy resin, and 0.7 parts of modified amine epoxy curing agent TDC-3361.

Abstract
The invention discloses a metal member casting technology. The metal member casting technology comprises the following steps of (1) manufacturing a mould pattern, (2) manufacturing a silica gel outermould, (3) manufacturing a wax mould, (4) modeling and (5) pouring, sand shakeout and finishing. According to the metal member casting technology, a wax lost precision casting technology, a gypsum type casting technology and a self-hardened resin sand casting technology are combined, modified grafting is carried out on a casting modeling system, and the metal member casting technology is successfully invented. It is indicated that through technological property test, technical analysis and production application of the novel technology, the novel casting method has the characteristics of refined casting surface, good casting quality, large specification and dimension, good glancing flatness, low cost, short production period, rapid forming, good collapsibility, dry reclamation and recycling of materials, less pollution and energy saving, and a metal member casting bottleneck is solved. The metal member casting technology is applied to various alloy casting forming.
Description
technical field [0001] The invention belongs to the technical field of casting technology, and in particular relates to a metal component casting technology. Background technique [0002] Casting process is one of the basic processes of modern machinery manufacturing industry. Metal component casting is to smelt metal into liquid metal that meets certain requirements, and pour it into the casting cavity to obtain predetermined shape, size and performance after cooling, solidification and cleaning. casting process. Commonly used casting techniques in the prior art include resin sand casting, lost wax precision casting, plaster casting and the like. The disadvantage of resin sand casting is that it is rough, the shape is not vivid, and complex shapes cannot be made; the shape of lost wax precision casting is delicate, and complex shapes can be completed, but its process is complex, costly, and takes a long time, and it can only make small products. It cannot be made into a l...
