Automated transfer and press forming device for a mold-frame in automatic transfer and pressure forming system of casting mold

The present invention relates to a molding machine automatic feeding device and method in the automatic transfer of the casting mold, pressure molding system, and more particularly, automatically introduced through a release agent supply unit, a binder supply unit, a sand supply unit, and a water supply unit. A raw material mixer tank is formed to integrally mix the raw materials. The raw material mixed through the raw material mixer is formed as one molding yarn, and the molding yarn is supplied to the inside of the raw material supply hopper formed at each of the left and right sides of the upper plate of the main body. In the automatic conveying, pressure molding system of the casting mold, which is configured to be automatically dropped and filled into the mold through the space portion formed on the surface of the main body plate while transported by each conveyor, automatic molding apparatus and method It is about.

In general, the working process using mold dies starts with model making. Models are usually made in a pattern shop separate from castings. The model is filled with casting sand around the model, and in the case of casting sand using fireclay as a binder, it is compacted until the required hardness is achieved. At this time, in the case of a chemical binder, it is hardened chemically after pressing by hand or chopped lightly mechanically.

Generally, the mold is divided into two types of upper and lower molds, and after the molding sand is chopped, the model is taken out and space is reassembled to leave the space occupied by the model inside the mold. After the casting is completed, a core should be used to leave holes or other spaces inside the core, and the core is made of a casting sand and a caking agent, which is sufficient strength even if molten metal is injected after being inserted into the mold. Should have hardness and fire resistance.

Therefore, the model makes the outer shape of the casting, and the shape inside the casting is made by the core. On the other hand, the actual casting operation starts with melting, and the molten solution is transferred from the melting to the ladle to fill the ladle to complete solidification of the molten metal. When the solidification is completed, the castings are taken out of the molds, the casting sands attached to the casting surface are shaken off, and the gatesprue runners and the risers attached to the castings are removed. Here, the pressure is to serve as a warehouse to compensate for the lack of molten metal caused by the shrinkage of the metal during the solidification of the casting. The finished casting is subjected to stress relief or special heat treatment as necessary, or inspected by various methods to determine whether there are any abnormalities, and then to be shipped.

On the other hand, in the process of the casting operation consisting of such a process, the prototype or model to be cast is located in the molding sand box, the molding sand box, the molding sand box is then transported to the filling device to the compression production system The casting work is being done through. Such a structure can compress another mold box when filling one mold box with sand.

As various working steps are carried out in the mold box, a number of circular plates are used which have a circle on the surface which is returned to the initial station. Simultaneously filling one mold box while the other mold box is compressed increases the throughput of the mold box per unit time. However, such as complete assembly of the mold box to the round or model plate carrier, followed by assembling the filling frame around the mold box, filling with sand and separating the round or model plate and filling frame from the mold box again after compression. There is still a drawback of wasting time. In addition, since the work of flattening and separating castings, such as taps, is performed manually, the workability is notably low, and the reliability of the castings, such as taping balls, is not uniform, so that the reliability is low. There are many problems with the risk of an accident.

In addition, the molding company to be injected into the mold frame is a situation that the filling through the manual work, there is a problem that the productivity is reduced while the efficiency of the work is reduced.

The present invention has been made to actively solve the above problems, by implementing the unmanned automation of the molding work of castings, such as casting molds to improve the workability and improve the quality of the castings, the risk of safety accidents remarkably The present invention provides an automatic molding machine feeder and method in an automatic transfer and pressure molding system of a casting mold, which can automatically supply a molding sand in which a mold release agent, a binder, sand, and water are integrally formed in the mold mold. There is a purpose.

As a means for achieving the above technical problem, the present invention forms a raw material mixer tank for integrally mixing the release agent supply unit, the binder supply unit, the sand supply unit, and the raw material automatically introduced through the water supply unit, the raw material The raw material mixed through the mixer is formed into one molding yarn and the molding yarn is supplied to the inside of the raw material supply hopper formed at the left and right sides of the main body plate, and then transported through each conveyor to form a space formed on the surface of the main body plate. In the automatic transfer, pressure molding system of the casting mold is configured to be automatically dropped and filled in the mold through the mold, automatic molding apparatus and method.

Automatic molding machine supplying apparatus according to the present invention has a feature that the efficiency and productivity of the work is higher than when compared to the conventional method of filling through the manual work by automatically supplying the molding yarn to be injected into the mold.

And, the supply of the mold, the means for pressurizing the sand filled in the mold, the process of separating the mold and the mold portion, and the structure that can automatically move the separated mold to the casting process Since the molding company can automatically supply a fixed amount, and the flat work can be performed at a uniform pressure, the quality of the casting can be improved, thereby improving reliability.
