Description

Technical Field

[0001] The utility model relates to the technical field of porous brick production, in particular to a mould for making porous red bricks. Background Art

[0002] As a new type of brick material, porous bricks are made through molds by designing new processing technology and designing multiple groups of holes in the brick body. While ensuring the structural strength and load-bearing capacity of the brick body, compared with traditional solid bricks, they greatly reduce the energy consumption during production and to a certain extent also reduce the cost of transportation after production.

[0003] In the process of making porous bricks, when the porous bricks are pressed for production, it is easy to find that the porous bricks produced after pressing cannot be conveniently taken out of the mold after production pressing. Since the blank is wrapped on the forming column, the holes of the porous bricks contact the forming column of the mold and generate large friction, which may cause damage to the porous bricks during the demolding process. How to invent a mold for making porous red bricks to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a mold for making porous red bricks, aiming to improve the situation that when the porous bricks are pressed during production, it is easy to take the porous bricks produced after pressing out of the mold after production pressing. Since the blank is wrapped on the forming column, the holes of the porous bricks contact with the forming column of the mold, resulting in large friction, which may cause damage to the porous bricks during the demolding process.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a mold for making porous red bricks, comprising a base, telescopic rods are arranged on both sides of the base, the base is connected with a lower mold and a support plate, one end of the support plate is provided with a sealing piston rod, an upper pressing plate and a fixing cylinder are arranged on the upper end of the telescopic rod, vent holes are symmetrically opened on both sides of the outer wall of the fixing cylinder, a fixing seat and a pressing plate are arranged on one side of the upper pressing plate, a plurality of evenly distributed punching rods are connected to the fixing seat, a fixing rod and an elastic line are arranged inside the punching rod, a blocking block is arranged at one end of the punching rod, and a telescopic spring is arranged between the fixing seat and the pressing plate.

[0007] Preferably, the base is fixedly connected to the telescopic rod and the support plate, the base and the lower mold are detachably connected, the support plate is "L" shaped, the upper end of the support plate is fixedly connected to the sealing piston rod, the other end of the sealing piston rod is interference fit with the inner wall of the fixed cylinder, and the fixed cylinder is fixedly connected to the upper pressure plate.

[0008] Preferably, the upper pressure plate is fixedly connected to the movable end of the telescopic rod, a cavity is provided inside the end of the upper pressure plate connected to the fixed tube, a plurality of square diversion grooves are provided on the inner wall of one side of the cavity, and the lower end of the upper pressure plate is fixedly connected to the fixed seat.

[0009] Preferably, a placement groove is provided on the lower side wall of the fixing seat, the inner wall of the placement groove away from the opening is fixedly connected to one end of the telescopic spring, the other end of the telescopic spring is fixedly connected to the pressing plate, the fixing seat is fixedly connected to the punching rod, and an exhaust hole is provided between the side wall of one end of the punching rod and the inner wall of the diversion groove.

[0010] By adopting the above technical solution, when the upper pressing plate is raised after the pressing is completed, the force of the pressing plate on the telescopic spring is reduced, so that the pressing plate is moved away from the fixed seat through the elastic recovery of the telescopic spring, and the outer wall of the punching rod is scraped, so that the pressed hole bricks can be easily demoulded.

[0011] Preferably, one end of the punching rod away from the fixing seat vertically penetrates the side wall of the pressing plate, and the lower side wall of the pressing plate is fixedly connected with an anti-sticking layer.

[0012] By adopting the above technical solution, it is possible to prevent the brick mud from sticking to the surface of the pressing plate during pressing, thereby ensuring production quality.

[0013] Preferably, both ends of the fixing rod are fixedly connected to the inner wall of one end of the exhaust hole away from the diversion groove, the middle outer wall of the fixing rod is fixedly connected to the elastic line, the other end of the elastic line is fixedly connected to the blocking block, and the blocking block is sealed to the exhaust hole.

[0014] By adopting the above technical scheme, after the pressing is completed, while the upper pressing plate rises, the cavity, the diverter groove and the exhaust hole are filled with air through the vent hole, and then the cavity is squeezed by the sealing piston rod. Through the action of pressure, the gas separates the sealing block and the exhaust hole, and the elastic line is stretched, so that the gas is discharged into the holes of the pressed brick mud, so that a gap is generated between the outer wall of the punching rod and the hole, and the telescopic spring and the pressing plate are cooperated to ensure rapid demoulding while avoiding sticking, and ensure production quality.

[0015] The beneficial effects of the utility model are:

[0016] After the die pressing is completed, the upper pressing plate rises and the air holes are used to fill the cavity, the diverter groove and the exhaust hole. Then, the gas in the cavity is squeezed by the sealing piston rod. Through the action of pressure, the gas separates the sealing block and the exhaust hole, and the elastic line is stretched, thereby discharging the gas into the holes of the pressed brick mud, so that a gap is generated between the outer wall of the punching rod and the hole. At the same time, the force of the pressing plate on the telescopic spring is reduced, so that the pressing plate is moved away from the fixed seat through the elastic recovery of the telescopic spring, and the outer wall of the punching rod is scraped, so as to facilitate the demoulding of the pressed hole bricks. The anti-sticking layer can prevent the brick mud from sticking to the surface of the pressing plate during pressing, thereby avoiding sticking and damage while quickly demoulding to ensure production quality.

[0027] It should be noted that: when the upper pressing plate 4 is raised after the pressing is completed, the force of the pressing plate 8 on the telescopic spring 17 is reduced, so that the pressing plate 8 is moved away from the fixed seat 12 through the elastic recovery of the telescopic spring 17, and the outer wall of the punching rod 11 is scraped, so as to facilitate the demoulding of the pressed hole bricks; and the anti-sticking layer 10 can prevent the brick mud from sticking to the surface of the pressing plate 8 during pressing, thereby ensuring the production quality.
