Abstract
The invention refers to a kind of pressing founding and casting method, which is used to produce colored alloy foundry goods. The realizing method is: the alloy fusant enters the pressure room through batch casting device and casting aperture sliding block, after the casting, the gate sliding block closes the pressure room, the indenter up runs, the alloy fusant is formed, pressure maintained, condensed under pressure. The efficiency is high, the quality is good, and the process reclaiming rate is high.
Description
Technical field:
The present invention relates to a kind of extrusion casint pouring procedure.
Background technology:
Existing extrusion casting method is pressing chamber artificial cast suitable for reading, and the matched moulds injection is a feature then, and its whole production processing step was divided into for eight steps, that is: open upper and lower land area 1, successively and carry out the die cavity cleaning and coat; 2, manually the chamber is suitable for reading to pour into from pressing with alloy melt; 3, matched moulds; 4, type is filled in injection; 5, pressurize is solidified; 6, open counterdie, break stub bar; 7, pressure head ejects stub bar; 8, open the patrix backhaul and eject foundry goods.Because adopt to press chamber artificial cast suitable for reading, existing extrusion casting method has following shortcoming: 1, need contain from crucible with pony ladle and get melt the chamber is suitable for reading to pour into from pressing, it is big therefore to pour into a mould difficulty, and operation is inconvenient, labour intensity height, and protection against oxidation difficulty; 2, must be after cast finishes could matched moulds die casting, therefore to fill the process of type long from being poured into pressurization, the melt temperature drop is big, casting quality is difficult to assurance; 3, for preventing to fill the quality problems that the melt temperature drop causes before the type, must improve the melt cast temperature, so melting energy consumption height, the alloying component scaling loss is big, the air-breathing oxidation tendency of melt is big.
Summary of the invention:
The purpose of the method for the present invention is that overcomes the above-mentioned defective of existing extrusion casint pouring procedure, and the extrusion casint pouring procedure of a kind of high efficiency, technical process simplification, low energy consumption is provided.
For achieving the above object, extrusion casint pouring procedure involved in the present invention comprises: matched moulds → pour into a mould → close cast gate → injection is filled type → pressurize and is solidified → the die sinking pickup, during cast, adopt and press chamber side apparatus for pouring, comprise and press chamber side quantitative pouring apparatus 5, gate sliding block 6, in the casting process, gate sliding block 6 is in pouring position, alloy melt 8 is pressed chamber 7 by pressing chamber side quantitative pouring apparatus 5 and gate sliding block 6 to enter, gate sliding block 6 slides into rapidly and fills the type position then, the sealing cast gate, and pressure head 9 up promotion alloy melts 8 enter die cavity, after filling type and finishing, pressure head 9 continues the pressurization of the alloy melt in the casting mold, and back die sinking, the injection pressure head 9 up stub bars that eject are solidified in pressurize, backhaul ejects foundry goods, and gate sliding block 6 is returned to pouring position again.
The inventive method is compared with existing extrusion casint pouring procedure has following advantage:
Adopt and press chamber side quantitative pouring apparatus 5, make alloy melt can take artificial cast or the cast of machine automatic ration, process choice is flexible; Adopt and press chamber side quantitative pouring apparatus 5, make casting process not influenced by the opening and closing mould, shortened the process cycles cycle, improved production efficiency; Adopt and press chamber side quantitative pouring apparatus 5, make the time shortening of filling type, thereby reduced the melt cast temperature, solved the problem that the alloy melt scaling loss is big under the high temperature, coagulation defect is many, improved the casting process recovery rate, and reduced the melting energy consumption from being poured into; Owing to press chamber side quantitative pouring apparatus 5 to link to each other with pressing chamber 7, avoided alloy melt to contact to greatest extent, for the protection against oxidation of alloy melt is provided convenience with extraneous by gate sliding block 6.
Description of drawings:
Fig. 1 is an extrusion casint pouring procedure operation principle schematic diagram involved in the present invention:
Wherein: 1-patrix; 2-upper bolster; 3-die side slide block; 4-counterdie; 5-pressure chamber side quantitative pouring apparatus; 6-gate sliding block; 7-pressure chamber; 8-alloy melt; 9-pressure head; 10-ejecting mechanism.
The specific embodiment:
The present invention is further illustrated below in conjunction with Figure of description 1 and case study on implementation:
Case study on implementation is an example with the extrusion casint of magnesium alloy hub, and its technical process is:
1, level mould, coat, matched moulds, pressure head reset;
2, cast: magnesium alloy fused mass is pressed in the chamber 7 by pressing chamber side quantitative pouring apparatus 5, gate sliding block 6 to be poured into, and gate sliding block 6 slides into along the Z direction rapidly and fills the type position subsequently;
3, fill type, pressurize, solidify: press the magnesium alloy fused mass in the chamber 7 to enter die cavity rapidly under the effect of pressure head 9, after filling type and finishing, pressure head 9 continues the magnesium alloy fused mass pressurize in the casting mold is solidified fully until foundry goods;
4, die sinking pickup: casting solidification and die sinking after pressurize a period of time, pressure head 9 is up simultaneously, ejects stub bar, and backhaul ejecting mechanism 10 ejects foundry goods in the up process of patrix;
5, pressure head 9, gate sliding block 6, ejecting mechanism reset 10, enter next working cycles.
The inventive method is used for the extrusion casint production of magnesium alloy hub, can solves effectively in the magnesium alloy pouring process that the protection difficulty is big, problem such as low, the complex technical process of melting scaling loss technology recovery rate big, foundry goods under the high temperature.
Claims (1)
1. extrusion casint pouring procedure, technology is: matched moulds → pour into a mould → close cast gate → injection is filled type → pressurize and is solidified → the die sinking pickup, it is characterized in that: adopt and press chamber side apparatus for pouring, comprise and press chamber side quantitative pouring apparatus 5, gate sliding block 6, during cast, gate sliding block 6 is in pouring position, alloy melt 8 is pressed chamber 7 by pressing chamber side quantitative pouring apparatus 5 and gate sliding block 6 to enter, gate sliding block 6 slides into rapidly and fills the type position then, the sealing cast gate, pressure head 9 up promotion alloy melts 8 enter die cavity, after filling type and finishing, pressure head 9 continues the pressurization of the alloy melt in the casting mold is solidified fully until foundry goods.
