Abstract
The invention relates to a metal casting manufacture procedure and a metal casting method for pre-formed ceramic cores. The metal casting manufacture procedure and the metal casting method comprise the following steps of: (a) performing injection molding on at least one ceramic material by utilizing a die to form at least two ceramic cores with pre-formed bodies; (b) assembling the ceramic cores and sintering; (c) wrapping an outer frame on the outer surfaces of the ceramic cores; (d) pouring at least one metal liquid into the ceramic cores, and solidifying to form cast pieces; and (e) breaking the ceramic cores to take the cast pieces out. By the steps, the cast pieces which are stable in quality and sizes can be manufactured effectively by utilizing the design of the ceramic cores, and the manufacturing speed is quickened simultaneously.
Description
Technical field
The present invention refers to a kind of a kind of preformed ceramic core metal casting processing procedure and method thereof that quality, dimensionally stable promote manufacturing speed simultaneously of effectively producing especially for a kind of preformed ceramic core metal casting method for making is provided.
Background technology
At present, in the method for traditional automation cast metal, need usually many loaded down with trivial details steps cured as penetrating, be stained with slurry, take off cured, sintering etc.; This worker's method is to be prone to introduce impurity.When the motlten metal release of pressure, oxygen is imported into and forms metal oxide layer in the mould, along with each casting changes process parameter, then has more impurity to be introduced into.
Therefore when this metal material of castable ceramic, the quality of its making and speed all can't effectively promote.
Summary of the invention
Main purpose of the present invention is to provide a kind of preformed ceramic core metal casting processing procedure and method thereof; Solve the existing existing quality instability of foundry goods production method and Production Time slow problem, reach and effectively produce the practical improvement that quality, dimensionally stable promote manufacturing speed simultaneously.
The present invention is a kind of preformed ceramic core metal casting processing procedure and method thereof, and its step comprises: (a) get at least one ceramic material and utilize mould that pottery is carried out at least two ceramic cores with predetermined body of ejection formation formation; (b) with carrying out sintering after those ceramic core assemblings, perhaps assemble behind this ceramic core sintering; (c) coat a housing in those ceramic core outer surfaces; (d) form a foundry goods with solidifying at least one those ceramic cores of metal liquid casting; (e) at last those ceramic cores are broken the taking-up foundry goods.
Wherein this mould includes at least one mold and at least one bed die;
Wherein the sintering of (b) step is to utilize a ceramics furnace to carry out sintering operation;
Wherein this housing be metal material or ceramic material one of them;
Wherein this housing carries out precompressed through a pneumatic cylinder, oil hydraulic cylinder or manual mode.
The invention has the advantages that: processing procedure of the present invention and method can effectively be produced quality, dimensionally stable and reach the practical improvement that promotes manufacturing speed simultaneously.

The specific embodiment
Shown in accompanying drawing 1 to accompanying drawing 5, be the block flow diagram～enforcement sketch map four of preferred embodiment of the present invention, find out that by knowing among the figure the present invention is a kind of preformed ceramic core metal casting processing procedure and method thereof, its step comprises:
(a) get at least one ceramic material and utilize mould 1 that pottery is carried out ejection formation to form at least two ceramic cores 2 with predetermined body;
(b) with carrying out sintering after those ceramic core 2 assemblings;
(c) coat a housing 3 in those ceramic core 2 outer surfaces;
(d) form a foundry goods 5 with solidifying at least one metal liquid 4 those ceramic cores 2 of casting;
(e) at last those ceramic cores 2 are broken taking-up foundry goods 5.
By above-mentioned step, and (b) sintering of step is to utilize a ceramics furnace to carry out sintering operation, and this mould 1 includes at least one mold 11 and at least one bed die 12 again; Again this housing 3 be metal material or ceramic material one of them; In addition this housing 3 is through a pneumatic cylinder, oil hydraulic cylinder or manually carry out precompressed, so the present invention can utilize the machine automation to produce in a large number, and brand-new production method is provided; Effectively promote the problem of foundry goods 5 manufacturing speeds; Make foundry goods 5 fabricating quality and size more stable, more can break people, create brand-new commercial economy and be worth casting general cognition.
Shown in accompanying drawing 6; Be the present invention's block flow diagram of a preferred embodiment again; Find out by knowing among the figure; The preparation method of present embodiment is different with last embodiment to be (b) step, and wherein present embodiment is assembled after with those ceramic core sintering, and all the other method flows are all identical with last embodiment.
