Abstract
The invention provides a method for manufacturing a bimetallic seamless plastic insert casting piece. The method comprises following steps: A. prefabricating a metal piece to be die-casted according to demands; B. placing the prefabricated metal piece to be die-casted into the cavity of a die-casting die, closing the die, pouring liquid metal of a melting state into the die, and obtaining a seamless bimetallic casting through a die-casting molding manner; C. removing burrs of the bimetallic casting; D. machining the bimetallic casting whose burrs are removed; E. performing anodic oxidation or other surface treatments on the machined bimetallic casting; and F. performing other surface decoration treatments on the bimetallic casting after the bimetallic casting is subjected to anodic oxidation or other surface treatments. By employing the method for manufacturing the bimetallic seamless plastic insert casting work piece, manpower and material resources can be saved, the efficiency is high, the productivity is high, the cost is low, and needed shapes and structures can be manufactured on the metal piece to be die-casted, so that machining is not needed or less needed. The method is suitable for manufacturing shells of mobile phones, flat computers, notebook computers and cameras.

Technical field
The present invention relates to die-casting technique field, particularly relate to the production method of the seamless embedding foundry work part of a kind of bimetallic.
Background technology
The metal shell production method of current existing high-end handsets, panel computer, notebook computer, camera is: carried out being machined into finished product by metal (aluminium alloy, stainless steel, titanium alloy) blank after repeatedly forging and stamping are formed as preliminary configuration again, or using metal blank directly to carry out being machined into finished product, mechanical processing process needs a large amount of loaded down with trivial details processing by CNC.The a large amount of wasting manpower and material resources's resource of process, efficiency is low, the cost that production capacity is low and high, can not meet huge market demand.
The production method being now badly in need of the seamless embedding foundry work part of a kind of bimetallic solves an above-mentioned difficult problem.
Summary of the invention
For above-mentioned prior art, technical problem to be solved by this invention is to provide one and uses manpower and material resources sparingly resource, and efficiency is high, and production capacity is high and cost is low, does not need the production method of the seamless embedding foundry work part of bimetallic of machining or a small amount of machining.
In order to solve the problems of the technologies described above, the invention provides the production method of the seamless embedding foundry work part of a kind of bimetallic, comprising the following steps:
A. the prefabricated metal works treating die casting on request;
B. prefabricated is treated that compression mod die cavity put into by die-cast metal workpiece, matched moulds injects the liquid metal of molten molten state, and die cast becomes seamless composite casting;
C. composite casting is removed burr.
Further improvement of the present invention is, the production method of described bimetallic is seamless embedding foundry work part is further comprising the steps of:
D. the composite casting after removal burr is carried out part machined.
Further improvement of the present invention is, the production method of described bimetallic is seamless embedding foundry work part is further comprising the steps of:
E. the composite casting after part machined is carried out anodic oxidation or other surface treatments.
Further improvement of the present invention is, the production method of described bimetallic is seamless embedding foundry work part is further comprising the steps of:
F. the composite casting after anodic oxidation or other surface treatments is carried out other incrustation process again.
Further improvement of the present invention is, described metal works is Al alloy parts, stainless steel work-piece, titanium alloy workpiece.
Further improvement of the present invention is, described liquid metal is the liquid metal of aluminium alloy, magnesium alloy, kirsite.
Further improvement of the present invention is, described composite casting is mainly used in the housing of mobile phone, panel computer, notebook computer, camera.
Compared with prior art; the invention has the advantages that; this invention adopts and prefabricated is treated that compression mod die cavity put into by die-cast metal workpiece; matched moulds injects the liquid metal of molten molten state; die cast becomes seamless composite casting; then composite casting is removed burr, carry out part machined, carry out anodic oxidation or other surface treatments etc.; The production method of this bimetallic is seamless embedding foundry work part can use manpower and material resources sparingly resource, and efficiency is high, and production capacity is high and cost is low, and because treating shape, the structure that die-cast metal workpiece can be produced needs, therefore the present invention does not need machining or a small amount of machining.
