Description

[0001] The present invention relates to a double-

The present invention relates to a double heat insulation brick molding machine, and more particularly, to a double heat insulation brick molding machine which has a good productivity and allows a wall of a building to be installed quickly, easily, and easily.

Generally, when the wall of the building is made to be insulated by the brick, the bricks are stacked at a predetermined interval inside and outside, and the styrofoam is interposed in the space between them. Since the construction is difficult and the construction period is long, Which is not economical due to a large amount of water, and a gap is formed between the styrofoam and the wall.

Therefore, in order to solve such a problem, conventionally, there has been proposed a molding frame main body which is formed as a four-sided surface portion and a bottom surface portion on the front, rear, left and right sides and a space is formed therein, and a hinge provided on the seating surface portion, A lid fixing means provided on the outside of the right side surface portion and provided for preventing the opening of the lid plate by pressing and fixing the upper surface of the lid plate by the rotation of the turning knob, A plurality of push rods provided on the upper surface of the mold body and operated by a hydraulic medium so that the push rods penetrate the bottom surface of the mold body and slide up and down into the inner space of the mold body; A molding frame body fixed to the upper surface of the mold frame, Accordingly, a double insulation brick having a reinforced insulation such as polyurethane or the like is provided. Thus, a double insulation brick manufacturing apparatus for building a heat insulation material between a brick and a brick for easily and easily installing the insulation wall (Patent No. 10- 1196290) have been proposed.

However, in such a double-adiabatic brick manufacturing apparatus, the cover plate is completely opened each time the double-layered heat insulation brick is manufactured, and one brick is placed on each of the left and right sides of the mold body, and then an appropriate amount of polyurethane is injected into the space between the bricks It is necessary to cover the cover plate and then fix the cover plate so that the cover plate is not opened by operating the cover fixing means. When the injected polyurethane is hardened after the foaming to extract the completed double insulation brick, the injected foamed polyurethane hardens The operator has to manually repeat the process of waiting until the lid fixing means is reversed to release the lid plate from the fixed state and completely open the lid plate again. Therefore, the operation for laying out and extracting the bricks is very troublesome and inconvenient Of course, it's time-consuming. There is a problem that the worker is easily fatigued and the productivity is lowered.

In addition, since the size of the cradle for holding the brick is limited, when the size of the brick is changed, it is necessary to use a mold body corresponding to the size of the mold. Therefore, There is a problem that the manufacturing cost is increased.

In addition, since the bricks embracing the left and right sides of the mold body are manufactured by a general manufacturing method and are not made to have exactly the same size (thickness), even if there is a slight difference in size, When a part of the polyurethane foam is covered with the cover plate, the polyurethane foam is leaked out through a gap between the lower surface and the upper surface of the smaller brick, so that the hardness of the polyurethane hardened after foaming between the bricks is reduced, And thus the entire cured state is poor and a long curing time is required.

In addition, since the bricks are placed to be completely inserted into the inside of the mold body, the operator can not directly take out the bricks after the double heat insulation brick is manufactured. Therefore, a plurality of push rods are provided on the bottom surface of the mold body Since the operation cylinder is installed to penetrate through the plurality of formed push rod mounting holes and operate to slide up and down into the internal space of the forming mold body, the extraction structure and the process are complicated, and the repetitive operation of the push rod, Foreign matter is caught between the rod mounting holes, and friction caused by the contact of the foreign matter with the surfaces of the rod mounting holes causes leakage of the injected polyurethane.

In addition, while the insulation effect by polyurethane can be obtained, there is also a problem that it is vulnerable to fire and moisture because it can not control flame retarding and moisture.

The present invention has been made in view of the above-mentioned conventional points of the present invention, and it is an object of the present invention to provide a double-sided brick which can increase the productivity remarkably and simultaneously form bricks of various sizes using a single device, To provide an insulating brick molding machine.

In addition, the present invention provides a double-layered insulating brick which can prevent the leakage of injected polyurethane and shorten the curing time and at the same time, Thereby providing a molding machine.

In order to accomplish the above object, the present invention provides a molding machine comprising: a mold having an upper surface and an upper surface of each of outer side surfaces of bricks positioned on left and right sides exposed so that bricks of various sizes can be easily inserted or extracted; A cover which is formed so as to cover only a space between the bricks and the inner surface of the upper surface of the bricks so that the left and right widths are spaced apart from each other in the open upper surface of the forming mold, Hot water pipes which circulate inside the cover to promote foaming and curing of the polyurethane injected into the space between the bricks, and a water supply pipe interposed between the upper surface of the base and the lower surface of the molding, The upper surface of the bricks placed on the left and right sides is always brought into close contact with the lower surface of the cover so that the foamed polyurethane leaks Characterized in that different installed on the air bag and the base that does not occur to provide a double heat insulating brick molding machine that is configured to include a switch to open and close the door automatically.

It is another object of the present invention to provide a double thermal insulation brick molding machine in which a double insulation brick is provided with a flame retardant and a moisture absorbing function in addition to thermal insulation by injecting polyurethane containing a fire retardant and charcoal powder into a space between bricks for foaming. .

The double-layered thermal insulation brick molding machine according to the present invention is characterized in that the bricks can be quickly and easily put in or taken out, as well as the polyurethane foaming and curing time are greatly shortened. Thus, the workability is very good, And the polyurethane is not leaked during the foaming process, and the foaming and curing conditions are excellent.

In addition, since the single-unit bricks can be used to form the double-layered bricks by using bricks of various sizes, there is no need to provide a molding frame of various sizes, so that the initial cost and the manufacturing cost can be greatly reduced .

In addition, by forming the double insulation bricks using the polyurethane added with the nonflammable material and the charcoal powder, fire prevention and moisture control effect by flame retarding and moisture absorbing action are obtained in addition to insulation.

The double-layered thermal insulation brick molding machine according to the present invention shown in Figs. 1 to 5 includes a molding frame 10, a lid 20, a hot water pipe 30, 30 ', a pressing member 40, .

The forming frame 10 has front and rear walls 11 and 11 'opened on the top surface and having a height proportional to the height of the bricks la that respectively face the left and right sides of the inside as described later, (12) and (12) and a bottom surface (13) of low height.

When the bricks 1a having the same height are placed on the left and right sides of the bottom surface 13 of the molding die 10, the height of the left and right walls 12 and 12 ' The upper portion of the bricks except for the height of the left and right walls is exposed to the outside from the bottom surface 13 at each outer side of the bricks.

The reason for lowering the height of the left and right walls 12 and 12 'and thus exposing the upper portions of the outer side surfaces of the bricks la respectively on the left and right is that the polyurethane The left and right sides of the double-layered heat-resistant brick 1, which has been molded so as to become a body with the bricks after being foamed and foamed, can be directly extracted by the operator with both hands.

In the middle of the inner surface of the front wall 12, a molding groove 12a of a coupling protrusion 1c protruding frontward is formed in the middle of the front face of the double-layered heat brick 2. In the middle of the inner surface of the rear wall 12 ' The molding protrusion 12b of the engaging groove 1d for engaging the engaging protrusion is protruded and the molding recess 12c of the isolating protrusion 1e protruding downward in the middle of the bottom surface of the bottom surface 13 so as to maintain the vertical distance therebetween, Is formed so as to intersect the front and rear.

The joining protrusions 1c and the coupling grooves 1d are for joining together and tightly connecting the double-heat-insulating bricks 1 when the double-heat-insulating bricks 1 are laterally formed, and the isolating protrusion 1e is for vertically constructing the double- It is intended to form a space for interposing the cement mortar between the inner and outer portions of the upper and lower double-layered bricks.

On the other hand, the mold frame 10 is formed so that the distance between the front and rear walls 11 and 11 'and the left and right walls 12 and 12' When bricks having left and right widths smaller than the maximum size of the bricks are placed on the left and right sides of the bottom surface 13, the bricks are placed between the outer surfaces of the bricks and the inner surfaces of the left and right walls Side support bars 14 formed at left and right widths proportional to the intervals, respectively, to prevent the bricks from being pushed outward.

When the rear surface of the brick 1a having a length shorter than the length between the front and rear walls is brought into close contact with the inner surface of the rear wall 11 'and the front surface is placed so as to be isolated from the inner surface of the front wall 11, A front support plate 15 formed to have a front and rear thickness proportional to the distance between the front surface and the front wall and having an intermediate portion 15a corresponding to the molding groove 12a may be mounted to prevent the brick from being pushed forward .

The front and rear lengths of the lid 20 are proportional to the front and rear surfaces of the front and rear walls 11 and 11 ' The upper surface of the bricks 10 is formed to have a size enough to cover only the inner portion of each of the upper surfaces of the bricks and a space formed by horizontally inserting the bricks 1a on the left and right sides of the upper surface.

Therefore, when the bricks la are placed on the left and right sides of the mold 10 one by one and the lid 20 is covered, the height of the left and right walls 12 and 12 ' And the upper portion of each upper surface which is not covered by the lid is exposed to the outside.

The lid 20 is formed by covering the inside of the upper surface of the bricks la laid in the left and right sides of the forming die 10 so that the polyurethane 1b injected into the space between the bricks leaks to the outside So that the consumption and the weight of the raw material for manufacturing the lid can be reduced to the maximum, thereby achieving cost reduction as well as opening and closing effect.

The hot water pipes 30 and 30 'are installed so as to be embedded in the middle of the bottom surface 13 and in the middle of the lid 20 respectively corresponding to the space between the bricks 1a.

Hot water of approximately 40 to 50 ° C is injected into the hot water pipes 30 and 30 'through a hose connected to each of the hot water pipes 30', thereby circulating the hot water pipes 30 and 30 'through the space between the bricks 1a into which the polyurethane 1b is injected. The polyurethane 1b injected into the space is rapidly and smoothly foamed and hardened in a short period of time.

The pressing member 40 is provided on the upper surface of the base 10a and includes a housing 41 having an opened upper surface and an airbag 42 accommodated in the housing and pressing the forming die 10 positioned on the upper surface thereof .

Such a pressing member 40 is formed by placing a brick 1a on the right and left sides of the forming die 10 and then injecting polyurethane 1b into a space between them and closing the lid 20 with a separate air compressor When the compressed air is supplied to the airbag 42 through the supply port provided with the valve, the inflating force generated as the airbag is inflated upward pressurizes the forming mold placed on the upper surface thereof as a whole.

The upper and lower surfaces of the front and rear walls 11 and 11 'of the forming die 10 and the upper surfaces of the bricks la placed in the mold 10 closely contact each other, The injected space is sealed so that leakage does not occur during the foaming and curing process.

However, the bricks (1a) can be manufactured by stamping in the same frame by the conditions such as the mixing ratio of the materials such as clay and sand or cement and sand, and the temperature in the process of bending and drying by kneading the frame, There are bricks that are not the same and are manufactured differently, albeit to a lesser extent.

When the upper surface of the brick having the higher height among the bricks is closely attached to the lower surface of the lid 20 when the bricks 1a are placed on the right and left sides of the mold frame 10 and the lid 20 is covered, The upper surface of the brick having a low height is not in close contact with the lower surface of the lid, so that even if there is a slight clearance therebetween, the polyurethane 1b leaks. The airbag 42 pushes up the molding frame, When the upper surface of the brick having a low height is not in contact with the brick, the portion where the brick with a low height is located is increased in proportion to the height difference so that the upper portion of the molding brick is pushed up, So that leakage does not occur.

At this time, even if there is a difference in the height of the bricks la laid on the left and right sides of the molding die 10, the difference is small, so that the airbag 42 pushes up the portion of the bricks where the lower brick is located Since the left and right sides of the lid 20 are formed so as to cover only the respective inner portions of the upper surfaces of the bricks laid on the left and right sides, even if one side of the molding frame is lifted by the airbag, Are all in close contact with the lower surface of the cover.

The switch 50 has a cylinder 51 and a cylinder rod 52 which are mounted on the base 10a so as to pivot at a hinge axis 50a and one end is fixed to one side of the lid 20, And an opening / closing rod 53 for vertically connecting the upper end of the rod.

The opening and closing device 50 covers or opens the upper surface of the forming die 10 by horizontally and vertically rotating the lid 20 horizontally and vertically at an angle of 90 degrees.

That is, when the cylinder 51 is driven in reverse, the cylinder rod 52 is moved backward to rotate the lid 20 in the reverse direction so as to be in a horizontal state covering the upper surface of the forming die 10, As the rod advances, the lid is rotated in a forward direction to bring the upper surface of the forming die into a vertical state.

The lower end of the cylinder 51 is connected to the hinge shaft 50a on the base 10a by closing and opening the lid 20 in the horizontal and vertical directions, And the upper end of the cylinder rod 52 is provided so as to be rotatable with respect to the opening and closing rod 53. Each time the cylinder is driven forward and backward, the cylinder serves as the axis of the hinge axis and the cylinder rod serves as the axis of the opening- Respectively.

On the other hand, the polyurethane 1b to be injected into the space between the bricks 1a laid on the left and right sides of the forming die 10 is filled with either the nonflammable material or the charcoal powder, Insulation bricks are not only adiabatic, they also provide the effect of preventing fire by flame-retarding action or controlling humidity by moisture absorption action.

Since the lid 20 is closed by the opening and closing device 50, the operation of extracting the molded double-layered brick 1 is very simple because the brick molding machine according to the present invention having the above- There are advantages.

When the lid 20 is opened by lowering the height of the left and right walls 12 and 12 'of the forming die 10, the upper and lower portions of the upper and lower surfaces of the upper and lower surfaces of the double- Therefore, the operator can easily and quickly extract the double-layered heat-insulating bricks by holding his or her hands, and there is no need for a separate device for extracting the molded double-layered bricks, which simplifies the structure as a whole.

The hot water pipes 30 and 30 'are provided on the inner surfaces of the molding die 10 and the lid 20 to heat the space between the bricks 1a so that the injected polyurethane 1b can be quickly and smoothly heated Foamed and hardened, thereby making it possible to mass-produce the double heat-insulating bricks 1 in a short time.

Particularly, a pressing member 40 for supporting the forming die 10 is provided, and the lid 20 has a left-right width, which is an inner side portion of each upper surface of the right and left bricks la, And the compressed air is injected into the airbag 42 of the pressing member so that the upper surface of the placed bricks is brought into close contact with the lower surface of the lid 20, In addition, if there is a brick having a low height among the bricks, the corresponding portion of the airbag is further expanded in proportion to the height difference, so that the corresponding portion of the molding frame is further pushed up so that the brick having a low height is brought into close contact with the lower surface of the lid, There is also a feature to prevent leakage phenomenon.
