Abstract
Description
The present invention relates to a casting mold manufacturing apparatus for a casting mold, and more particularly, to a casting mold manufacturing apparatus for a casting mold, which is capable of easily moving a casting mold to be filled in a mold while sandwiching the casting mold, To a casting mold removing device for a casting mold.
In general, casting is performed in order to make a casting, and it is performed in order of designing of casting, preparation of casting method, preparation of model, dissolution and injection of molten metal, and finishing to product.
First, the casting method for the product to be made is an important matter of how to design and combine the mold (mold). In principle, it is necessary to divide the entire mold into two halves ), And it is preferable to design the product so that the molten metal does not return to every corner due to the incorporation of bubbles, inclusions, cracks due to reduction in volume at the time of solidification, lack of fluidity, It should be devised not to cause any defects.
As the material of the mold, there are sand, metal, etc., and it is appropriately selected in consideration of the number of products manufactured, the required dimensional accuracy, the shape of the product, and the like.
In the conventional casting method as described above, the upper outer surface of the wooden mold is treated, the resin is coated on the upper surface of the wooden mold, and the resin is coated on the resin to dry the resin. Then, glass wafers were adhered and dried on the laminated resin to prepare an upper mold, a resin was applied to the lower surface of the wooden mold and dried, and the film was coated with a resin, a laminate resin and glass wool sequentially on the resin, A casting was produced.
BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-1070582 (published on Oct. 05, 2011, entitled "Casting Casting Method").
The casting method according to the related art has a problem that it is difficult to reduce the time and cost required for proceeding a new casting process because the operator manually removes the casting mold filled in the mold after the casting process is completed, have.
Therefore, there is a need for improvement.
The present invention provides a molding sand removing device for a casting mold, which can easily remove molding sand packed in a mold while providing vibration by placing a casting mold on a seating block provided to be movable in a base frame and equipped with a vibrating part, There is a purpose.
The present invention provides a base frame comprising: a base frame having a plurality of reinforcing ribs and seated on a ground; A mounting block mounted on the base frame and supported by the casting mold and having a discharge slope for guiding the molding sand discharged from the casting mold to one side; A flow connection disposed between the seating block and the base frame for fluidly connecting the seating block to the base frame; And a vibration part installed in the seating block and generating vibration when power is supplied.
According to another aspect of the present invention, the seating block is formed with an opening on one side of the upper surface, and a casting slurry flowing into the upper side slides to one side and is sloped from the upper side to the lower side.
Further, the flow connection portion of the present invention may include: a plurality of first connection protrusions protruding from the base frame; A plurality of second connecting protrusions protruding from the seating block to face the first connecting protrusions; And an elastic member interposed between the base frame and the seating block to insert the first connection protrusion and the second connection protrusion.
Further, the present invention is characterized by further comprising a scattering prevention portion for guiding the foundry sand so that the casting sand discharged along the inclined slope is gathered to one side and stored in the collection box, and suppressing generation of dust while the casting sand is discharged.
In addition, the shatterproofing portion of the present invention may further include: a housing provided at one side of the seating block so as to accommodate molding sand falling from one opening of the seating block and provided with a collecting slope; A support bulkhead extending from the housing and integrally connected to the seating block; And a cover portion connected to the support partition and detachably attached to the housing and the seating block to cover the opening of the housing and the seating block.
The scattering prevention unit may further include a washing water supply unit for spraying water onto the molding sand discharged from the housing to prevent dust from being generated while the molding sand falls on the receptacle, A base plate installed and inclined downwardly; A plurality of nozzles installed on the support plate; And a supply pipe connected to the nozzle and supplying wash water to form a water film inside the base plate.
The casting mold removal device for a casting mold according to the present invention is characterized in that a casting mold which is seated on the upper surface of the seating block is vibrated so that the casting mold filled in the mold can be easily discharged There is an advantage that can be made.
Further, the casting sand removing device for a casting mold according to the present invention is provided with a discharge inclined surface through which a foundry sand is discharged to one side in a seating block, so that the foundry sand is discharged in a certain direction, and an operator can easily remove the foundry sand.
In the casting mold removing device for a casting mold according to the present invention, an elastic member is interposed between a first connecting protrusion protruding from the base frame and a second connecting protrusion protruded from the seating block, so that the seating block can be made to flow So that the casting mold can be supported in a flowable manner and the casting mold can be easily discharged from the casting mold.
Further, the casting mold removing device for a casting mold according to the present invention is provided with a scattering prevention part, so dust can be prevented from being generated when the casting sand is discharged, which can advantageously maintain the surrounding environment of the workplace pleasantly.
