Abstract
A die cast-form physical moulding is first designed by using Pro/Engineer, Unigraphic-II, Powershape or other three-dimensional moulding software in computer; a paper prototype of die cast form is then made up by transmitting the stereo optical moulding document to LOM machine tool, and after the prepared paper prototype is treated, it is taken as the mother template of silastic die; and after combining die and frame, silastic main material and hardening agent are injected into the die frame, vacuum bubble is eliminated for hardening and the mother template is with drawn to obtain the silastic die. The die producing process is fast, low in cost and suitable for manufacturing die for single-piece and small batch production.
Description
The invention belongs to the flash mould technical field, be a kind of fast metal mold producing technology method.
The nonmetal prototype of employing flash mould fabrication techniques of the prior art facts have proved it is effective, then still have many technical difficulties but make metal parts, particularly metal die.So although some flash mould method can directly be made metal parts at present, mostly is to obtain by indirect mode.Such as, 3 D plane printing SLA (Stereolithography Apparatus), fuse deposition manufacturing FDM (Fused Depoosition Modeling) and selective laser sintering SLS (Selected Laser Sintering) method process cured or resin mould, utilize the method for model casting to produce metal parts; Also can utilize SLS or 3 D-printing TDP (Three DimensionPrinting) method, select suitable Modeling Material, process and directly to cast to obtain metal parts for the casting mold cavity consistent of cast usefulness with part shape.
Said technology for quickly manufacturing models has the mould making process complexity in the employing prior art, and fabrication cycle is long, and die manufacturing cost is higher, is unfavorable for the shortcomings such as making of single-piece or small lot mould.
The present invention is directed to the weak point of all existence of prior art, propose a kind of new technology for rapidly manufacturing mould scheme.
The said technology for rapidly manufacturing mould of the present invention is to be crossed through the silicon rubber module by the prototype that rapid prototyping manufacturing RPM (PapidPrototype Manufacture) makes to be converted to gypsum mould or ceramic mould, is watered by gypsum mould or ceramic mould and outpours metal die.Specify as follows:
Design the three-dimensional solid modeling of mould casting mold on computers with 3D sculpting softwares such as Pro/Engineer, Unigraphic-II, Powershape.Output to layering object manufacturing LOM (Laminated ObjectManufacturing) lathe after saving as STL (Stereolithography) cubic light moulding file format, directly produce the papery prototype of mould casting mold.The papery prototype that LOM makes is handled through back, surface system, just can be used as female sample of silicon rubber mould, problems such as this manufacturing process need consider how to choose die joint, plug hole position.Make up framed after, silicon rubber host and curing agent proportionally mixed inject framedly, through vacuum defoamation, place under the room temperature and harden, dissect and take out female sample and can obtain silicon rubber mould.Outpour the gypsum mould or the ceramic mould of mould casting mold at the basic top-pour of silicon rubber mould, make zinc base alloy die in conjunction with foundry engieering at last.Owing to have contraction during the casting zinc base alloy die, should consider when carrying out solid modelling that therefore the processing characteristics machine of zinc-containing alloy shrinks rule, to determine the allowance of product.
Conventional method (generally adopting processing of CNC Digit Control Machine Tool or spark machined) is when making punching block, and the moulding cycle is long and cost is high.And adopt the said fast metal mold producing technology of the present invention, and can accelerate the manufacturing speed of mould, the moulding cycle of metal die is shortened, and utilize zinc-containing alloy to make metal die and can reduce cost of manufacture greatly, economize on the use of funds.In addition, the said process program of the present invention is applicable to the single-piece or the small lot batch manufacture of product, the needs of adaptation to market variations fast.
