The present invention relates to a machine part forging apparatus and a control method for forming the reaction vessel, and more particularly, to supply the molten metal to the mold formed to separate the upper and lower molds while quantitatively metering and supplying foreign substances in a closed space. Cooling pipes are installed on the outer periphery of the upper mold and the lower mold to cool by injecting air into the preheater and the plurality of insertion grooves, and a temperature sensor is installed in the mold to cool and heat the measured temperature to an appropriate temperature. It improves the quality of the product by maintaining it, and raises the product with the take-out pin formed while maintaining the airtight inside the mold and transfers it along the rail with the transfer cart, and forms the release agent injection hole in the transfer cart to release the mold release agent into the mold after product transfer. Machine parts forging apparatus for reaction furnace molding for direct pressure forging of complex mechanical parts continuously by spraying It relates to a control method.

In general, the casting technique is an economical method of forming a mold having an inverted space of a desired shape and injecting a high temperature liquid metal into the mold to obtain a shape.

Gravity die casting, low pressure die casting, vacuum die casting, etc., have been the foundations of existing non-ferrous casting methods. Recently, forging research and development has been actively conducted. It's going on. This vitalization of research and development is intrinsically linked to the demand for lightweighting in terms of environmental and economical aspects, as well as the purpose of creating high value-added companies in accordance with the demand for higher quality.

Among the existing casting methods, gravity casting and low pressure casting have a low solidification speed and low density due to shrinkage and gas defects.The mechanical properties of each part are low, the difference is large, and die casting has a very high injection speed during casting. It is used in the casting of cases that require low mechanical properties due to the mixing of gas and gas, and the squeeze method is also restricted by the shape and thickness of products due to the low mold temperature and fast injection speed. Most of the developed casting forging method is indirect pressurization, which is difficult for price competitiveness and development and mass production due to high mold production and machine manufacturing cost.

As described above, although the conventional gravity casting and low pressure casting are basically not limited in shape, size, and product thickness, products such as shrinkage and pinhole are relatively high because the mold temperature, the melt temperature, and the solidification time are long. Due to a decrease in density and a decrease in mechanical properties due to defects, a reduction in product weight due to light weight is not realized.

Particularly, in the case of a relatively large and complicated shape, the auto parts cannot meet the trend of light weight of the car and thus cannot escape the backwardness of the parts. Therefore, in order to solve the above problems, the limitations of the existing methods are obvious, and the development of new methods is required.

Current domestic and foreign producers have produced large quantities of nonferrous metals such as aluminum wheels by gravity casting and low pressure casting. However, this method increases the defect rate of the product due to the characteristics of the casting method, and has a problem of deteriorating the mechanical properties of the product, such as structure, strength, elongation. For this reason, conventional casting methods such as low pressure casting have produced only small (up to 18 inches) products. In addition, due to the characteristics of the process, the temperature of the mold should be maintained at about 380 ℃ ~ 400 ℃, there was a problem that the cycle time is not suitable for mass production.

For the above problems, cast forging has been proposed in the past (also referred to as high pressure casting or squeeze casting.) The forging method is used to solidify the molten metal under high pressure. This method has the advantage of being able to mass-produce castings with fine structure and good mechanical properties.

As described above, Korean Utility Model Publication No. 97-27522, which is a conventional technique of molten metal forging using nonferrous metal, has been proposed.

However, in the forging apparatus using the molten metal forging method of the prior art, the molten metal is mixed with oxides and foreign substances on the surface as the molten metal is directly supplied to the molten metal from the furnace in a state exposed to the outside through a transfer tool such as a ladle. Reduced quality, increased cycle time due to ladle transportation, increased production costs, increased maintenance costs due to the consumption of parts such as ladles that carry molten metals, There was a problem that risk always remained.

In addition, the molten metal forging method of the prior art is to manually melt the molten metal melted in the furnace in the ladle, the productivity is lowered by manufacturing only a single piece in a simple form as it is impossible to continuously supply the exact amount of molten metal There was a problem.

In addition, the molten metal forging apparatus of the prior art can not directly maintain the temperature of the mold in accordance with the change of the temperature and characteristics inside the mold by directly pressurizing the molten metal, and thus, directly to the molten metal for a long time regardless of the temperature change Since the contact to be made, there is a problem that the heat load is increased to reduce the life of the mold.

In addition, since the forging apparatus using the molten metal forging method of the prior art is injected in a situation in which the temperature of the mold is not recognized at the time of molten metal injection, when the molten metal is injected or the product is taken out without being preheated, cracks may occur due to a sudden drop in temperature. And there is a problem in that the quality of the product is degraded due to the change of nonferrous metal structure.

In addition, the molten metal forging method of the prior art has a problem that it is difficult to produce a variety of automation and various products as the operator taps the molten metal by manpower and compress and take out the transported molten metal to be taken out and transported, not by quantitative supply. .

In addition, in order to separate the product from the lower mold, the take-out pin formed inside the lower mold is formed to have a tapered portion having a tapered shape in which the diameter is reduced to the lower side of the lower mold and close to the top to minimize leakage of the melt. It is loosely formed to minimize the friction and connects the cooling pipe to the insertion groove formed at the center of the ejection pin to prevent cooling of the product and thermal deformation of the ejection pin, and minimizes leakage and wear and extends the life. .

In addition, it is easy to disassemble and assemble the forging machine by integrating the drive port of the transfer plate combined with the rod of the Shanghai Song Cylinder and the take-off pin up and down, which is formed in the lower die, up and down. This provides the effect of efficient maintenance.

In addition, the upper die and the lower die are separated, forming a transfer rail at the central position where the product is taken out, and transferring the taken out product in a state where it is placed on the transfer truck. It provides an effect.

In addition, as the mold is installed, a plurality of injection holes are formed to spray the release material on the upper portion of the transfer plate which is transferred by the rotation of the transfer wheel along the guide rail installed in the center of the main body for supplying hydraulic pressure, and automatically transferred along the rail. By spraying the release agent, the operator does not directly spray to prevent safety accidents, the application time is reduced and evenly sprayed to the entire mold provides the effect of improving the quality of the product.
