[0002] Porous bricks are a common building material containing many pores. They are generally made by pressing concrete paste into molds.

[0003] Currently, the method of forming porous brick blanks using molds generally involves filling the blank into the mold frame and then extruding it. This forming method is prone to quality problems at the holes of the brick blank and makes it difficult to separate the brick blank from the mold. Utility Model Content

[0004] The purpose of this utility model is to provide a porous brick pressing mold to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-hole brick pressing mold, comprising a worktable, a mold frame provided on the upper surface of the worktable, a support plate provided on the inner side of the mold frame, an extension rod fixedly installed at the bottom of the support plate extending downward, a drive rod connected inside the extension rod, a servo motor installed at the lower end of the drive rod, a mounting frame fixed on the upper surface of the worktable, a hydraulic push rod fixed on the upper surface of the mounting frame above the mold frame, a pressure plate fixed at the output end of the hydraulic push rod, a mounting seat fixed on the lower surface of the pressure plate, multiple hole-making rods provided inside the mounting seat, a top plate provided below the hole-making rods, guide rods installed on both sides of the top plate, the end of the guide rod away from the top plate being connected to the pressure plate, a return spring sleeved on the outer side of the guide rod, and a through hole for the hole-making rod to pass through on the top plate.

[0006] Preferably, the outer edge of the mold frame is provided with an ear plate, and a buckle plate is pressed on the ear plate. The buckle plate is connected to the workbench by mounting bolts.

[0007] Preferably, the support plate is embedded in the mold frame, and the extension rod at the bottom of the support plate is slidably connected to the worktable.

[0008] Preferably, the drive rod and the extension rod are connected by a thread.

[0009] Preferably, the mounting bases are evenly distributed in an array on the surface of the pressure plate, and the upper end of the hole-making rod is threadedly connected to the mounting base.

[0010] Preferably, the guide rod is fixedly connected to the top plate, and the guide rod and the pressure plate are connected by a through-type sliding connection.

[0011] Preferably, the perforations are provided in a one-to-one correspondence with the hole-making rods, and the inner diameter of the perforation is adapted to the outer diameter of the hole-making rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this porous brick pressing mold, the top plate can be pre-pressed in the mold frame, and the pressure plate can drive the hole-making rod to pass through the perforation and insert into the blank in the mold frame to make holes. After the brick blank is extruded and formed in the mold frame, the pressure plate will drive the hole-making rod to exit the brick blank. At this time, the return spring can push the top plate to temporarily press against the brick blank to avoid damaging the integrity of the hole edge of the brick blank during the process of the hole-making rod being pulled out. Only when the hole-making rod is completely removed from the brick blank will the pressure plate drive the top plate to leave the mold frame. The servo motor drives the drive rod to rotate, and the drive rod pushes the extension rod through the thread to drive the support plate to rise, which facilitates the demolding of the brick blank and the mold frame.

[0021] In one or more embodiments of this utility model, an ear plate 3 is provided on the outer edge of the mold frame 2, and a buckle plate 4 is pressed on the ear plate 3. The buckle plate 4 is connected to the workbench 1 by mounting bolts. The buckle plate 4 is tightened on the workbench 1 by mounting bolts, so that the mold frame 2 can be stably fastened to the workbench 1 by the ear plate 3 to prevent displacement.

[0022] Here, ear plates 3 can be set on the opposite two sides of the mold frame 2, or ear plates 3 can be set on the outer edges of the mold frame 2 around the perimeter according to actual needs, and one or more ear plates 3 can be set on each side.

[0023] In one or more embodiments of this utility model, the support plate 5 is embedded in the mold frame 2, and the extension rod 6 at the bottom of the support plate 5 is slidably connected to the worktable 1 through the plate. When the extension rod 6 slides up and down, the extension rod 6 can drive the support plate 5 to move up and down synchronously.

[0024] In one or more embodiments of this utility model, the drive rod 7 and the extension rod 6 are connected by a thread. When the drive rod 7 rotates, the drive rod 7 can push the extension rod 6 to rise or fall through the thread.

[0025] In one or more embodiments of this utility model, the mounting bases 12 are evenly distributed in an array on the surface of the pressure plate 11, and the upper end of the hole-making rod 13 is threadedly connected to the mounting base 12, which facilitates the installation or removal of the hole-making rod 13 on the pressure plate 11 through the mounting base 12.

[0026] In one or more embodiments of this utility model, the guide rod 14 is fixedly connected to the top plate 15, and the guide rod 14 is slidably connected to the pressure plate 11 through the guide rod 14, so that the top plate 15 can be adjusted up and down below the pressure plate 11 by means of the guide rod 14.

[0027] To ensure the stability of the movement of the top plate 15 relative to the pressure plate 11, guide rods 14 can be set on the four sides between the pressure plate 11 and the top plate 15. This can prevent the top plate 15 from shifting laterally relative to the pressure plate 11, and the number of guide rods 14 on each side can be set to one or more according to actual needs.

[0028] In one or more embodiments of this utility model, the perforation 17 and the hole-making rod 13 are provided in a one-to-one correspondence. The inner wall diameter of the perforation 17 is adapted to the outer wall diameter of the hole-making rod 13, so that the hole-making rod 13 can pass through the perforation 17 to work.

[0029] according to Figures 1-5 As shown, the blank is first poured into the mold frame 2, and then the hydraulic push rod 10 is activated. At this time, the output end of the hydraulic push rod 10 pushes the pressure plate 11 to move downward. The pressure plate 11 drives the hole-making rod 13 and the top plate 15 to move downward synchronously until the top plate 15 contacts the blank in the mold frame 2 and then pre-presses it. Then the pressure plate 11 continues to move downward. At this time, the pressure plate 11 will drive the hole-making rod 13 to pass through the through hole 17 on the top plate 15 and insert it into the blank to make a hole until the pressure plate 11 and the top plate 15 completely compact the blank in the mold frame 2. Then the output end of the hydraulic push rod 10 drives the pressure plate 11 to retract. At this time, the pressure plate 11 drives the hole-making rod 13 to be pulled out of the brick blank. When the hole-making rod 13 is pulled out, the return spring 16 pushes the top plate 15 to still press on the surface of the brick blank, which is beneficial to prevent damage to the integrity of the hole edge when the hole-making rod 13 is pulled out. When the hole-making rod 13 is completely pulled out, the pressure plate 11 drives the top plate 15 to exit the mold frame 2.

[0030] Then, the servo motor 8 is started, which drives the drive rod 7 to rotate. The drive rod 7 then pushes the extension rod 6 through the thread to lift the support plate 5 up inside the mold frame 2, which is beneficial for demolding and removing the brick blank inside the mold frame 2.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
