Description

[0001] DOES INJECTION APPARATUS FOR PRECISION CASTING [0002]
The present invention relates to a metering device for precise casting, and more particularly to a metering device for a precise casting which is capable of easily discharging molten metal from a ladle by a tilting part while a slide moving part having a load cell placed on a carriage part is moved forward and backward, So that the molten metal can be quickly interrupted by the intermittent portion.
Generally, the molten metal is put into a mold and solidified to make a metal product of a desired shape. The casting is classified into a cast iron casting, an aluminum alloy casting, a copper alloy casting and the like depending on the metal used. The inflow method.
The material of the mold is a mold made by engraving molding sand into a metal mold made by engraving a metal such as a sand mold or a steel, or a mixture of a synthetic resin hardened by heating and a sand mold on a pre-heated metal mold to form a thin shell mold And shell molds, which are made of casting molds, die castings, shell molds, etc., respectively.
In the case of a mold, such a casting forms a mold having a concave portion by pouring a heat-resistant metal body without causing any trouble in flowing a molten metal as a molten metal. At this time, since the mold continuously uses one mold, the casting is divided so that it can be easily taken out after solidification.
The casting molds must be taken out of the casting mold every time, so that the casting molds will be made as many as the number of products. At this time, a model made by dividing a model of a wooden product into several pieces is put into a mold, and the mold is made by sanding the mold around the mold, and then removing the mold.
In the next melting furnace, the molten metal is melted into the ladle, the molten metal is injected into the mold by using the ladle, and the product is taken out after waiting for hardening. At this time, if the sand mold is removed, the sand is shaved off and the surface of the casting is left as it is and finished with the product.
As a method of introducing the molten metal, there are gravity casting using gravity, die casting pushing the molten metal and pushing the molten metal into the mold, centrifugal casting using the centrifugal force to send the molten metal to every corner of the mold and pushing the molten metal with the explosion pressure There are injection casting methods in which a casting explosion casting, a mold is turned downward, a part of the casting is put on the surface of the casting material, and the surface of the casting material is pressurized with a gas to inject the casting material into the casting mold.
On the other hand, an automatic die casting apparatus and method of Patent Publication No. 10-0590418 (2006.06.09) have been proposed, and the molten steel is injected according to the type of the product and the position of the mold to increase the injection speed, So that it is possible to increase the versatility and productivity, and to improve the working environment by increasing the production efficiency. However, in order to enable the interruption of the molten steel injection to be operated by the timer There is a problem that accurate interruption can not be achieved due to a malfunction of the timer in the process. These problems cause defects in the product, increase the amount of material used, and lower the recovery rate.
On the other hand, in a control method and control system of an automatic pouring machine of Patent Publication No. 10-1314755 (Mar. 31, 2013, Sep. 27, 2013), slippage movement, elevation movement and forward movement are performed by respective servomotors, The molten metal discharged from the ladle is not correctly interrupted during the process of injecting the molten metal into the mold.
In addition, the same problem as described above has been inherited.
