Description

Technical Field

[0001] The utility model relates to the technical field of red brick production, in particular to a forming machine for producing sintered red bricks. Background Art

[0002] Red bricks are made of clay, shale, coal gangue and other raw materials. After being crushed, mixed and kneaded, they are manually or mechanically pressed into shape, and then dried and fired with an oxidizing flame at a temperature of about 900 degrees Celsius. They are sintered building bricks. With the vigorous development of the construction industry, sintered red bricks, as an important building material, are in increasing demand. In the preparation process of sintered red bricks, the brick raw materials need to be plasticized through molds before the next step of sintering.

[0003] In the prior art, when plasticizing the red bricks before sintering, the brick embryo is generally pushed out directly from the mold by a pushing structure. However, when the brick embryo is taken out by the pushing structure, during the pushing process, the multiple inner walls of the mold and the outer wall of the brick embryo are adhered and rubbed, which easily leads to the breakage of the brick material and affects the quality of the subsequent sintered red bricks. How to invent a sintered red brick forming machine to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a sintered red brick forming machine, which aims to improve the problem that when the brick embryo is taken out by the pushing structure, the multiple inner walls of the mold and the outer wall of the brick embryo are adhered and rubbed during the pushing process, which easily leads to the breakage of the brick material and affects the quality of the subsequent sintered red bricks.

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

[0006] The utility model provides a sintered red brick forming machine, comprising a base, a fixed plate and an upper template arranged on the base, a weighing platform installed on the upper end of the base, a lower template installed on the upper end of the weighing platform, a mounting frame installed on one side of the weighing platform, and a hydraulic rod installed on the upper end of the mounting frame;

[0007] The upper end of the fixed plate is fixedly connected to the output end of the hydraulic rod, and the lower end of the fixed plate is provided with fixed rods around it. The lower end of the fixed rod is provided with a limit block, and the lower ends of two of the limit blocks are provided with gear rods;

[0008] The inner wall of the upper template is slidably connected to the outer wall of the fixed rod, two symmetrical ear plates are installed at the lower end of the upper template, two symmetrical side plates are installed below the upper template, a fixed block is installed at one end of the side plate, a double-headed screw is installed on the inner wall of the fixed block, a gear is installed at one end of the double-headed screw, and an end plate is installed between the upper template and the side plates.

[0009] Preferably, the mounting frame and the weighing platform are an integrated structure, and the output end of the hydraulic rod is slidably connected to the inner wall of the mounting frame.

[0010] Preferably, the lower outer wall of the fixing plate is fixedly connected to the upper end of the fixing rod, and the fixing rod, the limiting block and the gear rod are an integrated structure.

[0011] By adopting the above technical solution, the hydraulic rod is driven to raise the fixed plate until the limit block on the fixed rod contacts the fixed plate. At this time, the hydraulic rod is continued to be driven to move the upper template below upward to demould the brick raw material embryo.

[0012] Preferably, a symmetrical sliding groove is provided on the lower surface of the upper template, and a sliding block which is slidably connected to the inner wall of the sliding groove is fixedly connected to one end of the side plate.

[0013] The outer wall of the double-head screw is threadedly connected to the inner wall of the fixing block.

[0014] The two ends of the double-headed screw are rotatably connected to the inner wall of the ear plate, and the outer wall of the gear is meshingly connected to one side of the gear rod.

[0015] By adopting the above technical solution, when the hydraulic rod drives the fixed plate to demould, the gear rod at the lower end of the fixed plate moves up and engages with the gear, driving the double-headed screw to rotate so that the side plates at both ends slide to both sides synchronously to disengage and contact the brick raw material embryo.

[0016] The beneficial effects of the utility model are:

[0017] When demoulding, the hydraulic rod is started upward to move the gear rod at the lower end of the fixed plate upward and engage with the gear, driving the double-headed screw to rotate, so that the side plates at both ends slide to both sides synchronously to disengage and contact with the brick raw materials. After the hydraulic rod is driven continuously, the fixed plate continues to move upward until the limit block presses against the upper template. The side plates and the upper template move upward at the same time to demould the upper template while the side plates expose the bricks formed on the lower template. When demoulding the formed bricks, the templates on both sides are disengaged first and then demoulding is performed, which effectively avoids the breakage of the bricks caused by friction between multiple side walls and the bricks during demoulding.

[0025] Example

[0026] Reference Figure 1-Figure 4 A sintered red brick forming machine comprises a base 1, a fixing plate 6 and an upper template 10 arranged on the base 1, a weighing platform 2 is installed on the upper end of the base 1, a lower template 3 is installed on the upper end of the weighing platform 2, a mounting frame 4 is installed on one side of the weighing platform 2, and a hydraulic rod 5 is installed on the upper end of the mounting frame 4;

[0027] The upper end of the fixed plate 6 is fixedly connected to the output end of the hydraulic rod 5, and the lower end of the fixed plate 6 is provided with a fixed rod 7 around it, and the lower end of the fixed rod 7 is provided with a limit block 8, wherein the lower ends of the two limit blocks 8 are provided with a gear rod 9;

[0028] The inner wall of the upper template 10 is slidably connected to the outer wall of the fixed rod 7. Two symmetrical ear plates 12 are installed at the lower end of the upper template 10. Two symmetrical side plates 13 are installed below the upper template 10. A fixing block 15 is installed at one end of the side plate 13. A double-headed screw 16 is installed on the inner wall of the fixing block 15. A gear 17 is installed at one end of the double-headed screw 16. An end plate 18 is installed between the upper template 10 and the side plates 13.

[0029] Furthermore; the mounting frame 4 and the weighing platform 2 are an integrated structure, the output end of the hydraulic rod 5 is slidably connected to the inner wall of the mounting frame 4, the lower outer wall of the fixed plate 6 and the upper end of the fixed rod 7 are fixedly connected, and the fixed rod 7, the limit block 8 and the gear rod 9 are an integrated structure.

[0030] It should be noted that: the hydraulic rod 5 is started to raise the fixed plate 6. When the lower end of the fixed plate 6 contacts the limit block 8 on the fixed rod 7, the hydraulic rod 5 is continued to be driven to move the upper template 10 below upward to demould the brick raw material embryo.

[0031] Furthermore, a symmetrical slide groove 11 is provided on the lower surface of the upper template 10, one end of the side plate 13 is fixedly connected to a slider 14 that is slidably connected to the inner wall of the slide groove 11, the outer wall of the double-headed screw 16 is threadedly connected to the inner wall of the fixed block 15, the two ends of the double-headed screw 16 are rotatably connected to the inner wall of the ear plate 12, and the outer wall of the gear 17 is meshingly connected to one side of the gear rod 9.

[0032] It should be noted that: when the hydraulic rod 5 rises to drive the fixed plate 6 for demoulding, the gear rod 9 at the lower end of the fixed plate 6 moves up and engages with the gear 17, driving the double-headed screw 16 to rotate. While the double-headed screw 16 rotates, the side plates 13 at both ends slide to both sides synchronously to disengage from the contact with the brick raw material embryo. The fixed plate 6 continues to move up to the limit block 8, driving the upper template 10 and the side plates 13 to move up at the same time for demoulding.

[0033] The working principle of this sintered red brick forming machine:

[0034] The brick raw material is placed on the lower template 3 and the weight of the raw material is determined by the weighing platform 2, and then the hydraulic rod 5 is started to descend to extrude the raw material. When demoulding, the hydraulic rod 5 is started upward to raise the fixed plate 6, and the toothed rod 9 at the lower end of the fixed plate 6 moves up and meshes with the gear 17, driving the double-headed screw 16 to rotate. While the double-headed screw 16 rotates, the side plates 13 at both ends slide to both sides synchronously to disengage from the contact with the brick raw material, and the fixed plate 6 continues to move upward until the limit block 8 is against the upper template 10 after the hydraulic rod 5 is driven. At the same time, the toothed rod 9 and the gear 17 stop meshing, and the side plate 13 and the upper template 10 move upward at the same time so that the upper template 10 is demoulded while the side plate 13 exposes the brick material formed on the lower template 3, and then the brick material on the lower template 3 is removed for the next step of sintering. When demoulding the molded brick material, the templates on both sides are first disengaged before demoulding, which effectively avoids the friction between multiple side walls and brick materials during demoulding and causes the brick material to break.

[0035] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
