Abstract
The present invention belongs to the field of rapid prototyping (RP) and producing technology, and is especially one kind of compound injection molding mold based on RP technology and its making process. The injection molding mold consists of one mold core made of heat resisting and pressure resisting liquid compound polymer material, and assembled metal mold frame as standard unit. The making process includes RP to produce product prototype, copying mold cavity with liquid thermoset epoxy resin, hot curing and machining, embedding the mold core into metal mold frame, machining cooling water channel and liftout unit, and assembling to form the mold. The making process has low cost and short period.
Description
Technical field
The invention belongs to rapid shaping and manufacturing technology field, relate in particular to a kind of composite injection moulding mould and manufacture method thereof based on the RP technology.
Background technology
Thermoplastic is after entering injection mold by the injection molding machine of plastic injection, cooling curing moulding plastics part.Because injection mold is in high-temperature high-pressure state work, mold materials need use metal (mould steel), traditionally through car, mill, machining mode manufacturings such as mill, numerical control, electric spark, chemical attack, long processing time, cost height.
Summary of the invention
The present invention is directed to shortcomings such as metal injection molded die manufacturing cycle length, cost height, a kind of quick, economic injection mold structure and manufacturing technology are provided.
The composite injection moulding mould that the present invention is based on the RP technology is configured to by core rod assembling metal pattern, and wherein core rod is a kind of liquid macroimolecule composite that can the withstand high temperatures high pressure, and the metal mould bases is the standard component of injection mold.
Manufacture method based on the composite injection moulding mould of RP technology is: (RP) produces product prototype fast by rapid shaping technique, adopt liquid thermosetting epoxy resin material to copy the die cavity of injection core, after heat cure processing and processing, core rod is inlayed into metal mould bases, and processing cooling water channel and liftout attachment, be assembled into injection mold at last.
The beneficial effect that the present invention is based on the composite injection moulding mould of RP technology is, because structure of the present invention adopts assembling composite core rod in the metal mould bases, therefore work in-process need not use car, mill, the high manufacturing process of cost such as digital control processing, electric spark and chemical attack, adopted the general metal mould bases standard component in market simultaneously, the manufacturing cost of mould reduces significantly, approximately has only 1/5th of former manufacturing process cost; In addition, owing to adopt rapid shaping technique and liquid thermosetting epoxide resin material to duplicate the core rod technology, manufacturing time shortens significantly, and the general week age that only needs is a kind of quick, economic mold machining technology.
The specific embodiment
The composite injection moulding mould that the present invention is based on the RP technology is made of metal mould bases and core rod, and wherein core rod is to be made by a kind of liquid macroimolecule composite that can the withstand high temperatures high pressure, and the metal mould bases is the standard component of injection mold.Liquid macroimolecule composite in the present embodiment is the thermosetting epoxy resin material.
Its manufacture method is: (RP) produces product prototype fast by rapid shaping technique, adopt liquid thermosetting epoxy resin material to copy the die cavity of injection core, after heat cure processing and processing, core rod is inlayed into metal mould bases, and processing cooling water channel and liftout attachment, be assembled into injection mold at last.
Rapid shaping technique in this preparation method (RP) is a prior art, the thermosetting epoxy resin material of liquid state is copied injection core after, its heat cure treatment process is as shown in the table.
The heat cure treatment process
