Description

Technical Field

[0001] The utility model relates to the technical field of brick making, and particularly relates to an upper and lower die connection mechanism of a block forming machine with adjustable height. Background Technique

[0002] When bricks are produced, a mold is needed to hold the raw materials for brick making. The mold is divided into an upper mold and a lower mold. The upper and lower molds are closed by an upper and lower die connection mechanism to form a complete mold. According to the different shapes of bricks, different upper and lower molds are needed to cooperate. The upper and lower die connection mechanism can conveniently and quickly position and install the upper and lower molds, avoiding the phenomenon of uneven alignment of holes in manual installation, making the mold closing more accurate, making the shape of the produced bricks more stable, the edges more flat, and reducing the probability of defective products.

[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: the connection between the existing upper and lower die connection mechanism of the block forming machine and the guide post is connected by a ferrule. After installation, it is impossible to quickly adjust the gap size between the brackets of the upper and lower dies. Therefore, when replacing the mold, the upper and lower die connection mechanism needs to be disassembled, the lower die bracket is separated from the upper and lower die connection mechanism, and the position is adjusted and reinstalled after adjustment. The adjustment steps are numerous and complex, and the adaptability is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an upper and lower die connection mechanism of a block forming machine with adjustable height, which is simple in lifting and strong in adaptability, aiming at the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: an upper and lower die connection mechanism of a block forming machine with adjustable height, including an upper die bracket and a support frame arranged below the upper die bracket. A lower die bracket is slidably arranged on the support frame. The lower die bracket includes a tray and a fixed sliding block that slidably penetrates through the tray and is slidably connected to the outer wall of the middle section of the support frame. The fixed sliding block includes a fixed groove plate with a bottom surface arranged on the tray and a loose sleeve that penetrates through the fixed groove plate and is in contact with the tray. A pressure groove plate that fits the outer wall of the loose sleeve is also arranged on the loose sleeve. A bolt is arranged between the fixed groove plate and the pressure groove plate, and a loose nut is engaged with the bolt. By tightening or loosening the loose nut, the tightness of the loose sleeve is adjusted, so that the tray and the fixed sliding block can slide freely or be fixed.

[0006] A further improvement is that: a lower die fixing groove is also arranged on the tray.

[0007] Further improvement: The elastic sleeve includes an upper sleeve body made of spring steel that fits against the inner wall of the pressure groove plate and a lower sleeve body made of spring steel that is fitted below the upper sleeve body. The outer wall of the lower sleeve body fits against the inner wall of the fixed groove plate, and through grooves for deformation are provided on both the upper sleeve body and the lower sleeve body.

[0008] Further improvement: The upper sleeve body is an inverted U-shaped block structure with an inner wall that fits against and is slidably connected to the support frame, and the lower sleeve body is a U-shaped block structure with an inner wall that fits against and is slidably connected to the support frame.

[0009] Further improvement: The inner wall of the fixed groove plate is provided with a U-shaped groove that fits against the outer wall of the elastic sleeve, and the inner wall of the pressure groove plate is provided with an inverted U-shaped groove that fits against the outer wall of the elastic sleeve.

[0010] After adopting the above technical solution, the beneficial effect of the present utility model is as follows: When the present utility model is in use, if it is necessary to adjust the height of the lower die holder, only the locking nut needs to be quickly loosened, so that the extrusion force of the pressure groove plate and the fixed groove plate on the elastic sleeve disappears. At this time, the elastic sleeve no longer generates high internal pressure and is fixedly attached to the support frame, so that the lower die holder can be adjusted in height along the support frame. Subsequently, the locking nut is re-locked to complete the height fixation of the lower die holder. The adjustment is simple and has few steps, is suitable for various dies with different heights, and has strong adaptability. Description of the Drawings

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Referring to Figures 1-6 As shown, the technical solution adopted in this specific implementation manner is as follows: an upper and lower die connection mechanism of a block molding machine with adjustable height, including an upper die support 1 and a support frame 2 arranged below the upper die support 1. A lower die support 3 is slidably arranged on the support frame 2. The lower die support 3 includes a tray 31 and a fixed sliding block 33 that slidably penetrates through the tray 31 and is slidably connected to the outer wall of the middle section of the support frame 2. The fixed sliding block 33 includes a fixed groove plate 333 with a bottom surface arranged on the tray 31 and a tightening sleeve 331 that penetrates through the fixed groove plate 333 and the tray 31. The tightening sleeve 331 includes an upper sleeve body 41 made of spring steel that fits against the inner wall of the pressure groove plate 332 and a lower sleeve body 42 made of spring steel that is fitted below the upper sleeve body 41. The outer wall of the lower sleeve body 42 fits against the inner wall of the fixed groove plate 333. Through grooves 43 for deformation are provided on both the upper sleeve body 41 and the lower sleeve body 42. A pressure groove plate 332 that fits against the outer wall of the tightening sleeve 331 is further provided on the tightening sleeve 331. A bolt 334 is provided between the fixed groove plate 333 and the pressure groove plate 332, and a tightening nut 335 is engaged with the bolt 334. By tightening or loosening the tightening nut 335, the tightness of the tightening sleeve 331 is adjusted, so that the tray 31 and the fixed sliding block 33 can slide freely or be fixed. During use, the lower die is arranged on the tray 31 of the lower die support 3, and the upper die is suspended below the upper die support 1. At this time, sliding the lower die support 3 can make the lower die and the upper die be clamped and fixed. Subsequently, fixing the lower die support 3 can complete the die installation and combination. When the lower die needs to be replaced, at this time, the tightening nut 335 on the bolt 334 can be loosened, so that the pressure provided by the tightening nut 335 is no longer applied to the fixed groove plate 333 and the pressure groove plate 332. Thus, the squeezing force of the fixed groove plate 333 and the pressure groove plate 332 on the tightening sleeve 331 disappears, and further, the inward deformation squeezing force generated by the upper sleeve body 41 and the lower sleeve body 42 of the tightening sleeve 331 disappears. At this time, the upper sleeve body 41 and the lower sleeve body 42 recover elastically along the through grooves 43. At this time, the tray 31 can be pulled to move up and down along the support frame 2 to adjust the height of the lower die support 3. After adjusting to a suitable position, the tightening nut 335 is tightened again to make it apply pressure on the pressure groove plate 332 and the fixed groove plate 333 again. Thus, the upper sleeve body 41 and the lower sleeve body 42 generate inward deformation and pressure again, so as to adhere and fix to the support frame 2. The adjustment is simple and the steps are few, suitable for various dies with different heights, and has strong adaptability;

[0020] The tray 31 is also provided with a lower mold fixing groove 32, which is beneficial to better position and fix the lower mold and prevent sliding;

[0021] The upper sleeve body 41 is an inverted U-shaped block structure with an inner wall that fits and is slidably connected to the support frame 2, and the lower sleeve body 42 is a U-shaped block structure with an inner wall that fits and is slidably connected to the support frame 2. This is beneficial for generating better lateral pressure when being squeezed by the fixing groove plate 333 and the pressing groove plate 332, and then applying a higher lateral pressure on the support frame 2 to obtain a more secure locking effect;

[0022] The inner wall of the fixing groove plate 333 is provided with a U-shaped groove that fits the outer wall of the elastic sleeve 331, and the inner wall of the pressing groove plate 332 is provided with an inverted U-shaped groove that fits the outer wall of the elastic sleeve 331. This is beneficial for better fitting between the fixing groove plate 333, the pressing groove plate 332 and the elastic sleeve 331, while ensuring the inward pressure of the elastic sleeve 331 and reducing the resistance when tightening the locking nut 335.

[0023] The working principle of the present utility model: When the present utility model is in use, the lower mold is arranged on the tray 31 of the lower mold support 3, and the upper mold is suspended below the upper mold support 1. At this time, sliding the lower mold support 3 can make the lower mold and the upper mold be combined and fixed. Subsequently, fixing the lower mold support 3 can complete the mold installation and combination. When the lower mold needs to be replaced, the locking nut 335 on the bolt 334 can be loosened at this time, so that the pressure provided by the locking nut 335 is no longer applied to the fixing groove plate 333 and the pressing groove plate 332. Thereby, the squeezing force of the fixing groove plate 333 and the pressing groove plate 332 on the elastic sleeve 331 disappears, and further the inward deformation squeezing force generated by the upper sleeve body 41 and the lower sleeve body 42 disappears. At this time, the upper sleeve body 41 and the lower sleeve body 42 are elastically restored along the through groove 43. At this time, the tray 31 can be pulled to move up and down along the support frame 2 to adjust the height of the lower mold support 3. After adjusting to the appropriate position, the locking nut 335 is tightened again to make it apply pressure on the pressing groove plate 332 and the fixing groove plate 333 again. Thereby, the upper sleeve body 41 and the lower sleeve body 42 generate inward deformation and pressure again, so as to be attached and fixed to the support frame 2. The adjustment is simple and the steps are few, suitable for various molds with different heights, and has strong adaptability.
