The present invention relates to a mold manufacturing system for manufacturing a cam shaft for an engine, and more particularly, to automate the manufacturing process of a mold for manufacturing a casting cam shaft for an engine by using sand coated with a thermosetting resin having an adhesive force. The present invention relates to a camshaft mold manufacturing automation system and a mold manufacturing method using the same to maintain uniformity and improve work efficiency to improve the quality and productivity of a cast product.

An engine camshaft is an important component installed in an engine that generates power, such as a vehicle, and performs a very important function in the operation of the engine.

In other words, the camshaft is one of the core parts of the engine that requires precision and durability as it is a very important part for operating the intake and exhaust valve devices in the engine cylinder by receiving the rotational motion from the crankshaft rotating.

Such camshafts are usually manufactured by forging or casting methods. In the manufacture of the camshafts by casting methods, the production of molds for casting is essential, and such molds are formed by coating phenol resin on sand particles to heat them. In case of adding sand granules, the phenol resin coating sand is made to have the adhesive force so that it can be molded into a specific shape.

Looking at the work process for producing the mold of the cam shaft by the casting method as described above step by step.

The main process in the mold fabrication process is a molding process for molding the upper and lower molds of the mold; The mold may be divided into a molding process in which a mold is applied to the inside of the upper mold and the lower mold formed by the molding process, the cold metal and the filter are correctly inserted, and then the upper mold and the lower mold are combined.

The molding process for forming the mold is performed in a mold molding machine.

The mold molding machine includes a preheating furnace, a sand dumping part, a heating furnace, and a mold extracting part, and the work is continuously performed while being circulated continuously.

In the preheating furnace, the preheating work is first performed by heating the mold having the camshaft shape assembled on the bogie to 300 ± 50 ℃.

The mold preheated in the preheating furnace moves to the sand dumping portion, and pours the thermosetting phenolic resin coated sand onto the heated mold.

That is, in the sand dumping part, the coating sand is applied to the surface of the preheated mold so that the phenol resin coated on the outer surface of the sand is adhesive by heat of the preheated mold, thereby forming a mold on the outer surface of the mold. To do that.

The mold is formed to have a predetermined thickness so that the coating sand not formed by the mold is recovered and reused.

After recovering the coating sand, the mold is moved to a heating furnace and cured by heating to 300 ° C.

That is, the heating furnace heats and bakes the outer shape of the mold formed by coating the mold.

The mold, which is fired and molded in the heating furnace, moves to the mold extraction unit and is separated from the mold while being extracted from the mold while the lower plate of the mold extraction unit is raised.

Through this operation, the mold is molded and extracted so that the upper plate and the lower plate are paired, respectively, and the molding process of the mold is completed.

When the molding process operation by the mold molding machine is completed, it leads to the molding process of the extracted upper template and the lower template.

In the molding process, the upper mold and the lower mold are formed in a pair so that the cold mold and the filter are precisely set at the corresponding positions in the extracted mold, and then the bond is injected, and the upper and lower molds respectively manufactured. Is molded by joining.

After the bonding is completed, the inlet trimming should be done to remove and clean foreign substances in the molten metal inlet area.

The phenol resin coated sand mold thus manufactured is cooled by putting molten metal into the mold made by the foundry sand, and finally, the foundry sand attached to the surface is removed to complete the casting operation, and then processed again to final camshaft. To prepare.

By the way, in the past, most of the molding work to complete the mold has been performed by the direct manpower of the worker.

Accompanying drawings FIG. 6 is a flow chart of a combination work operation by hand during the manufacture of a conventional mold, which shows that the work is performed sequentially and continuously by the personnel of three persons.

In other words, the mold separation, mold cleaning, drawing application, and chiller alignment are sequentially and repeatedly performed from the molding machine by the hands of the worker 2, the main worker, and the mold is separated from the assistants 1 and 3, respectively. Tell what you did.

Workers 1 and 3 are alternately placed in the mold received from the main worker, drawing the lower plate, installing the lower plate, inserting the chiller in the corresponding area of the lower plate, inserting the filter, cleaning the lower plate, and bonding to the bond injection line. In order to perform the work in the order of injection, top plate combination, switch operation of the molding machine, chiller preparation, and mold loading.

The molding work must be completed by a group of three workers within a predetermined time, and then proceeded to the next work process. It requires righteousness.

Conventional molding work has been made by the hand of the operator as described above, there were a variety of problems.

In other words, there is a risk that the mold plate in the less hardened state will be deformed during the extraction process, and the worker will spray the air spray gun by hand to apply the figure during the application of the figure. The difference causes uneven coating concentration.

In addition, as a continuous operation, the cold metal and the filter must be manually inserted on the lower plate by hand, and thus the accuracy of the work is reduced because it is a manual operation, and the product is damaged due to the scratching of the mold or the sand is released, leading to product defects. When the mold is molded by cooling, the mold deforms or the plastic deformation of the mold causes the adhesive force to deteriorate due to poor adhesion.

In addition, after shaping, using a whetstone artificially trimming the inlet and removing the foreign matter, the uniform work could not be performed, and foreign matter was introduced into the mold, which may cause product defects.

In particular, the odor caused by the heating of phenol resin and the spread of dust in the working process have been pointed out as a problem because it is detrimental to workers' health.

The present invention devised to improve such a problem is an unmanned automation of the overall work of the molding process by the cam shaft mold manufacturing automation system to dramatically improve the quality and work efficiency of the product by rapid and accurate work and using the same The purpose is to provide a method for manufacturing a mold.
