Description

Separating apparatus of base and flask with driving means for demolding < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a platen and a flask equipped with demolding means, and more particularly, to a flask equipped with a mold releasing means, When a mold is manufactured by separating a platen and a flask from each other, both sides of the platen are formed with a storage space opened at the top, and the storing space is provided with a drive for separating the flask upwards The flask and the platen can be easily separated from each other, the labor and the working time can be shortened, and the driving means on both sides can be moved up and down at the same speed by connecting the hydraulic unit with the tuning valve So that the flask is vertically upwardly separated without deviations, so that breakage of the base and the mold can be prevented, and the defective rate of the finally produced cast product The drive means is provided for deforming the surface plate and can be output relates to the flask.

In general, casting is a metal working technique in which molten metal is poured into a mold such as a sand mold or a metal mold and solidified to produce various types of cast products.

In order to obtain such a casting product, first, a prototype having a shape of the casting product must be provided.

A circular mold made of wood is called a wooden mold. Such a wooden mold is used as a semi-permanent wooden form by processing the wood material such as wood on the top of the plate, in the form of a cast product.

On the other hand, since most casting products are manufactured in a large size, the size of casting wooden molds is also often made large in order to manufacture a large casting product.

The casting mold is placed on the top of the casting mold, the casting mold is poured, the casting mold is separated from the flask by attaching a draw spike, which is a thin and pointed rod to the wooden mold, Respectively.

1 and 2, in the case of a large-sized wooden type, a wire W or the like is fixed to a fastening port 21 of a flask 20, and the wire W is hooked on a hook 1 of a crane, A physical impact was applied to the periphery of the platen 10 with a hammer or the like while the platen 20 was lifted upward and the platen 10 was dropped on the ground and separated to prepare a mold 40 .

However, in the case of removing the large-sized wooden piece, there is a tendency that a deviation occurs in the separation of the large-size wooden piece, resulting in breakage of the wooden or mold, resulting in a defective rate of the casting product.

In addition, when the base 10 is separated into a ground by a physical impact such as a hammer, a safety accident that is injured by an operator is caused by the base 10 falling to the ground, There is a problem that a lot of time and labor are consumed for separating the mold 20.

The circumference of the platen 10 is broken and the platen 10 needs to be manufactured again and the platen 10 is not separated vertically downward, ) And the mold 40 are also damaged, so that it is necessary to carry out the work after the repair, and there is also a problem that the defective rate of the finally produced cast product increases.

In order to solve the above-described conventional problems, the present invention is characterized in that a storage space having an open top is formed on both sides of a surface plate, and driving means for separating the flask upwardly by a variable length is provided in the storage space So that it is not only easy to separate the flask and the platen but also can shorten labor and work time.

Further, the driving means is connected to an oil pressure unit provided with a tuning valve so as to be able to move up and down at the same speed, and a guide core is formed on an upper surface of the base to guide the flask upward when the flask is separated upward, Another object of the present invention is to prevent breakage of the platen and the mold by separating the flask vertically upward without deviation, and to reduce the defective rate of the finally produced casting product.

In order to solve the above-mentioned problem, a base and a flask having driving means for demolding according to the present invention are provided with a base having a base on an upper surface for manufacturing a mold, The flask is mounted on the top of the platen. The platen is further provided with a storage space having an open top, and further includes driving means for separating the flask upwards by a variable length in the storage space. And a driving means for demoulding the mold.

The upper part of the storage space is further provided with a supporting plate for supporting the lower part of the flask and transmitting the upward force of the movable unit to the flask.

In addition, a guide core is further formed on one side of the upper surface of the base so as to guide the upper side of the base so as to prevent a deviation when the base and the flask are separated from each other.

According to the present invention, a storage space having an open top is formed on both sides of the table, and the storage space is provided with drive means for upwardly separating the flask by variable length, Not only is it simple, but also has the effect of shortening the labor force and the working time.

Further, the driving means is connected to an oil pressure unit provided with a tuning valve so as to be able to move up and down at the same speed, and a guide core is formed on an upper surface of the base to guide the flask upward when the flask is separated upward, It is possible to separate the flask vertically upward without any deviation to prevent breakage of the base and the mold, and to reduce the defective rate of the finally produced cast product.
