DETAILED DESCRIPTION
[0036] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0037] Example 1
[0038] Figures 1 to 7 The first embodiment of the present utility model is as follows: Figure 1 As shown, a continuous mold for autoclaved brick production includes a lower mold 1 and an upper mold 3. The upper mold 3 is installed on the pressure head of the brick press, and the lower mold 1 is installed just below the pressure head of the brick press. The continuous mold for autoclaved brick production also includes at least two material boxes 2, such as Figure 5 As shown, the material box 2 includes a box body 21, a box bottom plate 22, and a spring pin 23. The box body 21 is a cylinder with openings at both ends. The box bottom plate 22 is arranged at the bottom of the box body 21. The spring pins 23 are installed on the front and rear side surfaces of the bottom of the box body 21. The top of the spring pin 23 is spherical. The part of the spring pin 23 exposed from the inner wall of the box body 21 is spherical. The front and rear side surfaces of the box bottom plate 22 are provided with card grooves corresponding to the spring pin 23; the lower mold 1 includes an outer shell 12, a reset spring 15, and a top plate 17. The outer shell 12 is a box-shaped with an opening at the top. The top plate 17 is the same shape as the opening of the outer shell 12. The top plate 17 is placed in the outer shell 12, and the side of the top plate 17 is in contact with the side of the inner cavity of the outer shell 12. A reset spring 15 is arranged between the bottom of the top plate 17 and the bottom of the outer shell 12.
[0039] The lower mold 1 also includes a guide rod 16 and a bottom plate 13. The top of the guide rod 16 is connected to the bottom surface of the top plate 17. The reset spring 15 is sleeved on the guide rod 16. The bottom plate 13 is arranged at the bottom of the shell 12. The distance between the bottom of the guide rod 16 and the bottom plate 13 is greater than the height of the box body 21. By setting the guide rod 16, the reset spring 15 can be replaced to limit the lowest point of the stroke of the top plate 17. By setting the bottom plate 13, the bottom of the shell 12 can be welded to the bottom plate 13, and a fixing hole is set on the bottom plate 13 to facilitate the fixation of the lower mold 1. The guide rod 16 and the reset spring 15 are arranged in two groups. The lower mold 1 also includes a base 11. The shell 12 is entirely installed inside the base 11, and the top surface of the shell 12 is in contact with the top surface of the base 11. The length of the base 11 is greater than three times the length of the material box 2. By setting the length of the base 11 to be greater than three times the length of the material box 2, after the brick pressing is completed, the material box 2 containing the brick 5 can be pushed to one side of the base 11, and the material box 2 containing the raw materials 4 on the other side can be pushed under the upper mold 3. A slide groove is provided at the center of the length direction of the top surface of the base 11, and the width of the slide groove is equal to the width of the material box 2. By providing the slide groove, the position of the material box 2 is limited, so that it is convenient to push it directly under the upper mold 3.
[0040] The lower die 1 also includes a guide sleeve 14, which corresponds to a guide rod 16. The guide rod 16 is inserted into the guide sleeve 14, which is fixed on the bottom plate 13 and directly below the guide rod 16. The reset spring 15 is sleeved on the guide sleeve 14. The guide rod 16 is always inserted into the guide sleeve 14. When the reset spring 15 is extended to the maximum length, the top surface of the top plate 17 is flush with the top surface of the housing 12. At this time, the length of the guide rod 16 inserted into the guide sleeve 14 is the smallest; the pressure head 31 moves downward to push the top plate 17 downward until the bottom surface of the guide rod 16 contacts the bottom surface of the guide hole of the guide sleeve 14, and the top plate 17 stops. At this time, the length of the guide rod 16 inserted into the guide sleeve 14 is the largest. By setting the guide sleeve 14, the position of the top plate 17 can be limited to avoid jamming, thereby improving the stability of the equipment.
[0041] like Figure 5 As shown, the upper mold 3 includes a pressing head 31, a pressing rod 32, a demoulding spring 33, a guide block 34, and a clamping block 35.

The bottom frame of the pressing rod 32 is chamfered, a guide section is arranged at the bottom of the pressing rod 32, and a shoulder is arranged at the top of the guide section. The top of the pressing rod 32 passes through the demoulding spring 33 and the guide holes on the guide block 34 in sequence and then connects to the clamping block 35; a disengagement block 24 corresponding to the pressing rod 32 is arranged on the side of the material box 2, and a guide hole corresponding to the guide section at the bottom of the pressing rod 32 is arranged on the disengagement block 24.
[0042] When the pressing head 31 descends, the guide section at the bottom of the pressing rod 32 is first inserted into the guide hole on the disengagement block 24, and then the shoulder on the pressing rod 32 contacts the top surface of the disengagement block 24, and the pressing head 31 continues to descend until the pressing of the brick 5 is completed, and the demoulding spring 33 is gradually compressed during this process. When the pressing head 31 rises, the demoulding spring 33 presses down the box body 21 through the disengagement block 24 to ensure that the pressing head 31 is smoothly disengaged from the box body 21.
[0043] like Figure 6 As shown, the inner edges of the openings at both ends of the box body 21 are chamfered. By chamfering the inner edges of the openings at both ends of the box body 21, it is convenient to press the pressure head 31 and reset the box bottom plate 22.
[0044] Example 2

[0051] While one material box 2 is pressing bricks under the hydraulic brick machine, it feeds materials to another material box 2; after the brick pressing is completed, the material box 2 under the hydraulic brick machine is taken out and replaced with the material box 2 filled with raw materials 4. During operation, the material box 2 is placed on the base 11, and the box bottom plate 22 will not fall off with the support of the base 11. A certain amount of raw material 4 is loaded into the material box 2, and then the material box 2 is pushed to the center of the outer shell 12 just below the upper mold 3 along the slide groove on the base 11; the hydraulic brick machine is started, the upper mold 3 is pressed down, and the pressing head 31 is inserted into the box body 21 to contact the raw material 4. The pressing head 31 continues to press down, and the box bottom plate 22 is disengaged from the spring pin 23 and moves down with the top plate 17 until the guide rod 16 contacts the bottom plate 13; then the pressing head 31 continues to move down to the bottom of the set stroke to press the raw material 4 into a brick blank 5; the pressing head 31 returns, and the brick blank 5, the box bottom plate 22, and the top plate 17 are bounced up by the action of the reset spring 15, the brick blank 5 is pushed into the material box 2, the box bottom plate 22 resumes the engagement with the spring pin 23, and the top plate 17 is pushed to the top of the outer shell 12. At this time, push the entire material box 2 together with the brick blanks 5 inside to one side, push the material box 2 filled with raw materials 4 to the bottom of the pressure head 31, start the hydraulic brick press, and continue to press bricks. When using this continuous mold for brick pressing production, the work of adding raw materials 4 to the material box 2 can be completed during the downward process of the pressure head of the brick press, separating the feeding process; the generated brick blanks 5 are pushed into the material box 2, and the material box 2 is pushed aside and then taken out, which does not delay the work of the hydraulic brick press, does not need to take bricks from the mold, reduces the time spent on taking bricks, and improves production efficiency. The compaction of the raw materials 4 is completed in the outer shell 12, and the box body 21 only temporarily carries the raw materials 4, does not bear pressure, and does not need to be made as heavy as the lower mold, which saves costs and is convenient for pushing and switching.
