Description

Technical Field

[0001] The present invention relates to the technical field related to energy-saving building equipment, and in particular to an energy-saving building material production mold and a use process thereof. Background Art

[0002] In the construction industry, energy efficiency and efficiency have always been a core goal. To achieve this, researchers have continuously explored and innovated, resulting in the development of a new energy-saving building material. This material is an improvement on traditional clay bricks. Specifically, a certain proportion of industrial waste, including but not limited to spent refractory brick aggregate, fly ash, bottom ash, and stone dust, is added to the clay. After a special process, these waste materials are fully integrated with the clay, forming a brand-new building material.

[0003] After searching, it was found that the patent with announcement number CN210820080U discloses a forming device for the production of building materials. The operation process of this device is relatively cumbersome when in use. When starting to use this forming device, you need to remove the upper pressure plate first, and then adjust the connecting rod, fixing sleeve and support plate to the appropriate position through the fixing ring to ensure that the forming frame can be completely placed on the connecting rod and support plate. Next, push the lower hydraulic rod with the jack to the appropriate position of the forming frame, and then start filling the forming frame with concrete. When the concrete is filled, place the upper pressure plate in the forming frame that has been filled with concrete, and start the upper hydraulic rod to extend it downward. When the upper hydraulic rod is extended downward to the longest, it is also necessary to extend the lower hydraulic rod to make the entire concrete mold tighter to ensure the forming effect.

[0004] This demonstrates the significant shortcomings of the current molding process for energy-saving building materials. For one thing, the frequent replacement of molding frames increases operator workload and significantly reduces manufacturing efficiency, extending production cycles and failing to meet the demands of large-scale production. Furthermore, the increased adhesion between the energy-saving building materials and the molding frame after compression makes demolding difficult, making it difficult to remove the molded material. The process can even damage the material, increasing production costs and scrap rates. Summary of the Invention

[0005] The present invention proposes an energy-saving building material production mold and its use process, which has the advantages of multiple molding cavities and elastic demolding, and aims to effectively solve the problems of low efficiency in the building material manufacturing process and difficulty in demolding the material after molding mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a mold for producing energy-saving building materials, comprising: an upper mold and a lower mold, which are restricted to relative up and down movement by a guide piston assembly, and a return spring is provided on the outer side of the piston rod of the guide piston assembly to realize the relative distance between the upper mold and the lower mold; a support frame is installed at the bottom of the upper mold, which is pushed downward by a demoulding spring, and a pressure head is fastened to the bottom of the support frame; a forming cavity corresponding to the pressure head is opened on the surface of the lower mold, and the pressure head squeezes the raw material in the forming cavity to realize the manufacture of the brick body; a synchronous piston cylinder is installed on one side of the surface of the lower mold, and an inner cylinder is installed on the top of the inner side of the synchronous piston cylinder, and the piston rod of the synchronous piston cylinder is sealed with the inner side of the inner cylinder, and an electromagnetic valve for controlling the on and off of the inner cylinder and the synchronous piston cylinder is fixedly installed on the top of the outer side of the synchronous piston cylinder; after the brick body is manufactured, the upper mold drives the lower mold upward, and the piston rod of the synchronous piston cylinder squeezes the lubricating oil in the inner cylinder, so that the lower mold follows the upper mold to move upward synchronously, and the pressure head is pushed into the forming cavity by the elastic force of the demoulding spring to realize the ejection of the brick body.

[0007] Furthermore, a one-way valve is fixedly installed at the bottom of the piston rod of the synchronous piston cylinder.

[0008] Furthermore, a mold connected by a bracket is movably installed on the surface of the lower mold, and a forming spring is provided between the surface of the lower mold and the mold, which is pushed by the elastic force of the forming spring to achieve alignment of the mold and the molding cavity; an adjustment piston cylinder connected to the inner cylinder is fixedly installed on the side of the lower mold, and the piston rod of the adjustment piston cylinder drives the mold to move synchronously with the connecting frame, so as to control the alignment / offset of the mold and the molding cavity; a locking frame is fastened to the end of the support frame, and a locking slide pushed by the locking spring is movably installed on the bottom of the upper mold, and the locking slide can be used to limit the downward movement of the locking frame.

[0009] Furthermore, a shift telescopic rod is fastened to the bottom of the locking slide, and the bottom end of the shift telescopic rod is movably mounted on the surface of the lower mold. When the bracket on the mold pushes the shift telescopic rod, the locking slide and the locking frame are disengaged and the downward restriction on the locking frame is released.

[0010] Furthermore, the cross-section of the locking frame is in an "L" shape.

[0011] Furthermore, an anti-reverse seat is fixedly installed on the piston rod of the adjustment piston cylinder, and a fork frame for limiting the movement of the anti-reverse seat is movably installed on the bottom of the lower mold.

[0012] Furthermore, the anti-reverse seat has a conical shape.

[0013] Furthermore, a buffer cylinder is installed on the side of the mold, and a clearance is fitted between the buffer cylinder and the pressure head.

[0014] A process for using a mold for producing energy-saving building materials comprises the following steps:

[0015] S1. The upper die is fixed on the press. The press lifts the upper die, and the guide piston assembly drives the lower die to rise synchronously.

[0016] S2. Place a flat plate in the area directly below the forming cavity, and add the raw materials for preparing the brick body into the forming cavity.

[0017] S3. The press pushes the upper die downward, the lower die contacts the plate first, the upper die and the guide piston assembly compress the return spring, and the piston rod of the synchronous piston cylinder moves downward synchronously.

[0018] S4. The upper die drives the support frame downward, the pressure head presses the forming cavity, the support frame compresses the demoulding spring to the limit, and after the pressure head in the upper die applies the required pressure to the forming cavity, the demoulding spring is compressed and the piston rod of the synchronous piston cylinder detaches from the inner tube.

[0019] S5. The press drives the upper die to move upward. When the piston rod moves upward and approaches the bottom of the inner cylinder, the return spring pushes the guide piston assembly downward, so that the lower die is always pressed tightly against the flat plate. After the piston rod enters the inner cylinder, the upper die drives the lower die upward synchronously. The ram is pushed out of the forming cavity by the elastic force of the demoulding spring to achieve demoulding.

[0020] S6. After the upper die moves up to the top, the solenoid valve connects the inner cylinder and the inner cavity of the synchronous piston cylinder, and the hydraulic oil flows back into the inner cavity of the synchronous piston cylinder. Pushed by the return spring, the whole returns to its normal position and waits for the next stamping.

[0021] The present invention has the following beneficial effects:

[0022] The present invention provides a mold for producing energy-saving building materials and a process for its use. The lower mold portion of the mold is provided with multiple forming cavities. This design enables the efficient simultaneous production of multiple clay bricks mixed with industrial waste during a single complete mold closing operation. Compared to traditional molds that can only form a small number of bricks at a time, this multi-cavity design significantly improves production efficiency, meets the needs of large-scale industrial production, and helps promote the widespread application of energy-saving building materials in the market.

[0023] The support frame plays a crucial role in the mold closing process. As the mold closes, the support frame compresses and accumulates pressure in the demolding spring. When the molding operation is complete and the mold needs to be opened, the previously compressed and pressurized demolding spring releases its stored elastic force, pushing the ram in a stable and powerful manner. Under the action of the spring force, the ram evenly and smoothly ejects the finished clay brick from the mold cavity. The entire demolding process is clean and efficient, requiring no excessive human intervention, significantly reducing demolding time and ultimately achieving fast and efficient demolding. This effectively solves the difficulties and inefficiencies associated with traditional mold demolding and provides a strong guarantee for the efficient production of energy-saving building materials.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] In the first embodiment, the present application proposes an energy-saving building material production mold, which uses industrial waste as raw material for manufacturing bricks, so that the waste plays a reinforcing role in the bricks, thereby improving the compressive strength of the bricks.

[0035] In practice, clay is used as the primary raw material to provide the basic structure and plasticity of the brick. A certain proportion of waste materials (such as waste refractory brick aggregate, fly ash, bottom ash, stone dust, etc.) are crushed and mixed with the clay to form a blank with a certain degree of plasticity. The resulting material is then placed in a production mold, referred to herein, for shaping.

[0036] Specific, combined Figure 1 and Figure 2 As can be seen, the entire device consists of two main parts: the upper mold 1 and the lower mold 2. During use, the upper mold 1 can be fastened to the press using the ear holes reserved on the top, and the press is used to drive the upper mold 1 up and down, thereby bringing the upper mold 1 and the lower mold 2 closer to each other, that is, the mold closing process.

[0037] The four corners of the lower die 2 are each secured with a flange-fastened guide piston assembly 3, and the piston rod in the guide piston assembly 3 is fixedly connected to the upper die 1. This design not only ensures that only vertical relative movement is possible between the upper and lower dies 1 and 2, but also takes advantage of the limited extension length of the guide piston assembly 3. This allows the upper die 1, which continues to move upward, to drive the lower die 2 upward, even after the piston rod is fully extended from the guide piston assembly 3. A return spring 301, sleeved on the outer portion of the piston rod, is installed between the top of the guide piston assembly 3 and the bottom of the upper die 1. Under normal conditions, the lower die 2, pushed by the elastic force of the return spring 301, tends to move away from the upper die 1.

[0038] The bottom of the upper mold 1 is provided with a support frame 4 which is guided by multiple telescopic rods. Figure 6 As can be seen in the figure, a demoulding spring 401 located on the outer side of the telescopic rod is connected between the support frame 4 and the upper mold 1. Under normal circumstances, the support frame 4 is pushed by the elastic force of the demoulding spring 401 and guided by the telescopic rod, causing it to move downward and causing the telescopic rod to extend to its longest length. In addition, a plurality of pressure heads 5 are fastened with bolts at the bottom of the support frame 4. In this application, six pressure heads 5 are used as an example to ensure that six bricks can be manufactured simultaneously after one mold closing. In actual application, the number of pressure heads 5 is not limited to this and can be adaptively adjusted according to actual needs.

[0039] Correspondingly, from Figure 3 It can be seen that the surface of the lower mold 2 is provided with a forming cavity corresponding to the pressure head 5, that is, Figure 3 As shown in the middle A, when the upper mold 1 moves downward, the pressure head 5 is used to apply pressure to the forming cavity, thereby extruding the material in the forming cavity, thereby completing one-time mold closing to achieve the production of multiple energy-saving clay bricks.

[0040] In order to facilitate the removal of the brick from the forming cavity, Figure 1 and Figure 5It can be seen that a synchronous piston cylinder 7 is fastened with bolts on one side of the lower mold 2, and an inner cylinder 701 coaxially arranged with the synchronous piston cylinder 7 is fixedly connected to the top of the inner side of the synchronous piston cylinder 7. The piston rod of the synchronous piston cylinder 7 is sealed with the inner side of the inner cylinder 701. Figure 5 As can be seen, the bottom of the inner cylinder 701 is connected to the inner cavity of the synchronous piston cylinder 7. When the piston rod is located in the inner cavity of the inner cylinder 701, the inner cavity of the inner cylinder 701 and the chamber above the piston rod are separated from the inner cavity of the synchronous piston cylinder 7. A solenoid valve 702 is fixedly installed on the top of the outer side of the synchronous piston cylinder 7 to control the connection between this sealed chamber and the inner cavity of the synchronous piston cylinder 7. When the solenoid valve 702 is energized, it can open the passage between the inner cavity of the inner cylinder 701 and the inner cavity of the synchronous piston cylinder 7, allowing hydraulic oil to flow between the two.

[0041] In actual application, according to Figure 5 It can be seen that an oil filling port is provided on the top of the synchronous piston cylinder 7, which can be elastically sealed and can also be connected to the oil tank. The oil filling port can be used to add hydraulic oil into the synchronous piston cylinder 7 inner cavity.

[0042] Under normal conditions, the upper die 1 is fixed on the press. When the press is used to lift the upper die 1, the guide piston assembly 3 can drive the lower die 2 to rise synchronously. At this time, the piston rod of the synchronous piston cylinder 7 is at the top of the inner cavity of the inner cylinder 701, that is, Figure 5 Position shown.

[0043] When making bricks, a flat plate is placed beneath the lower mold 2, directly below the forming cavity. This allows the formed bricks to be stacked on the plate and easily transported using a forklift. When the press pushes the upper mold 1 downward, the lower mold 2 at its base contacts the plate first.

[0044] The raw materials for preparing the brick body are added to the forming cavity. As the upper die 1 continues to move downward, the upper die 1 and the guide piston assembly 3 compress and store the return spring 301. In this process, the piston rod of the synchronous piston cylinder 7 moves downward synchronously. Figure 5 It can be seen that a one-way valve 703 is fixedly installed at the bottom of the piston rod of the synchronous piston cylinder 7. The one-way valve 703 can realize the one-way upward flow of hydraulic oil in the lower chamber, ensuring that the piston rod in the synchronous piston cylinder 7 can move downward quickly when it moves downward.

[0045] As the upper mold 1 drives the support frame 4 downward, the ram 5 on the support frame 4 eventually presses into the mold cavity. As the upper mold 1 continues to descend, the pressure exerted by the ram 5 on the mold cavity increases. During this process, the support frame 4 simultaneously compresses the demolding spring 401 until it reaches its limit. Finally, as the ram 5 in the upper mold 1 applies the required pressure to the mold cavity, the demolding spring 401 is compressed, and the piston rod in the synchronous piston cylinder 7 is released from the inner barrel 701.

[0046] After the raw materials in the molding cavity are extruded and formed, the press drives the upper mold 1 to move upward. At this time, as the upper mold 1 drives the piston rod in the synchronous piston cylinder 7 upward and approaches the bottom of the inner cylinder 701, the return spring 301 pushes the guide piston assembly 3 downward, forcing the lower mold 2 to remain tightly pressed against the flat plate. When the piston rod enters the inner cylinder 701, the hydraulic oil in the inner cylinder 701 cannot be compressed, and the solenoid valve 702 is also in a blocked state at this time. Therefore, the upward movement of the upper mold 1 will drive the lower mold 2 to move upward synchronously, but at this time, the ram 5 is pushed by the elastic force of the demoulding spring 401 and still has a tendency to move downward. As the lower mold 2 continues to rise, the ram 5 is pushed out of the molding cavity by the elastic force of the demoulding spring 401, ensuring that the brick body in the molding cavity is easy to demold. When the upper mold 1 moves up to the top, the inner cylinder 701 and the inner cavity of the synchronous piston cylinder 7 are connected according to the solenoid valve 702. The hydraulic oil in the inner cylinder 701 flows into the inner cavity of the synchronous piston cylinder 7, and is pushed by the return spring 301 to force the whole to return to the normal position and wait for the next stamping.

[0047] After forming, the bricks are dried to remove excess moisture. They are then fired in a kiln. The firing temperature and time are strictly controlled based on the raw material properties and product requirements. During the firing process, the clay and waste materials in the bricks undergo physical and chemical changes, forming a brick with a certain strength and durability. The firing temperature is typically set between 950°C and 1300°C, and the firing time is 20 to 24 hours.

[0048] After firing, the bricks are inspected for quality, including appearance quality, dimensional accuracy, compressive strength, water absorption, etc. Qualified products are packaged and shipped, while unqualified products are reworked or scrapped.

[0049] Example 2 is a further improvement on Example 1. Since the bricks will require subsequent dimensional inspection, the manufacturing process described above shows that current bricks are primarily formed by pressing in a mold cavity. While their dimensions, such as length and width, are constrained by the mold cavity and relatively stable, their thickness and height are affected by the amount of raw material input. This instability in raw material input is influenced by many factors, including uneven mixing of raw material particles, inaccurate metering equipment, and uneven feeding speeds.

[0050] In order to prevent such problems, the second embodiment combines Figure 2 and Figure 3 It can be seen that the surface of the lower mold 2 is movably mounted with a mold 6, and multiple molds 6 are fixedly connected by brackets, forcing the multiple molds 6 to move horizontally along the surface of the lower mold 2 using the brackets. Figure 3As shown, when the mold 6 moves to the left limit, the mold 6 and the forming cavity are relatively offset; similarly, when the mold 6 moves to the right limit, the forming cavity and the mold 6 are aligned. Under normal circumstances, because the base of the lower mold 2 is mounted with a forming spring 602, the end of the forming spring 602 abuts against the mold 6. The elastic force of the forming spring 602 forces the mold 6 and the forming cavity to remain relatively aligned.

[0051] from Figure 1 、 Figure 4 and Figure 5 It can be seen that the side of the lower mold 2 has an adjustment piston cylinder 8 fixedly installed through a hydraulic cylinder frame. The adjustment piston cylinder 8 is connected to the inner cavity of the inner cylinder 701 through a hydraulic oil pipe. The outer side of the piston rod of the adjustment piston cylinder 8 is fixedly installed with a connecting frame 10. The connecting frame 10 is fixedly connected to the bottom of the mold 6. When the piston rod of the adjustment piston cylinder 8 is extended and retracted, the connecting frame 10 can drive the mold 6 to move back and forth. At the same time, combined with Figure 2 、 Figure 3 and Figure 6 As can be seen, a locking bracket 402 is bolted to the end of the support frame 4, with an L-shaped cross-section. Correspondingly, a locking slide 12 is movably mounted at the bottom of the upper mold 1. A locking spring 120 is connected between the locking slide 12 and the upper mold 1. The spring force of the spring 120 forces the locking slide 12 to move toward the locking bracket 402. The side of the locking slide 12 is approximately Z-shaped, and its bottom is provided with an inclined surface. Therefore, when the locking slide 12 moves above the support frame 4 and pushes the locking bracket 402 toward the locking bracket 12, the upward movement of the locking bracket 402, along the inclined surface, pushes the locking bracket 402 against the locking bracket 12, compressing the locking spring 120. Once the locking bracket 402 passes over the locking bracket 12, the spring force of the spring 120 pushes the locking bracket 12 below the locking bracket 402, thereby preventing the locking bracket 402 from descending. Moreover, a shift telescopic rod 11 is fixedly mounted on the bottom of the locking slide 12, and the bottom end of the shift telescopic rod 11 is movably mounted on the surface of the lower mold 2, such as Figure 3 As shown, when the mold 6 moves to the left limit, the bracket on the mold 6 will squeeze the shift telescopic rod 11, and the transmission of the shift telescopic rod 11 will cause the locking slide 12 to compress the locking spring 120 synchronously.

[0052] In actual application, under normal conditions, the forming spring 602 pushes the mold 6 to move to the right limit. At the same time, the locking spring 120 pushes the locking slide 12 to also move to the right limit.

[0053] Direction reference Figure 2 , Structure Reference Figure 4 and Figure 5As shown, when the press drives the upper die 1 downward, the lower die 2 is first pressed against the flat plate. At this point, because the mold 6 is aligned with the forming cavity, the raw material can be directly fed into the mold 6. After the raw material is delivered, it is pressed downward by the upper die 1. Consistent with the first embodiment, as the upper die 1 pushes the ram 5 downward, the ram 5 presses into the mold 6, simultaneously pressing and forming the mold 6 and the raw material in the forming cavity. When the ram 5's downward movement is blocked, the support frame 4 compresses the demolding spring 401, causing the support frame 4 to move relatively close to the upper die 1. During this process, the support frame 4 moves relatively close to the locking slide 12 and uses the support frame 4 to push the inclined surface of the locking slide 12, causing the locking slide 12 to move leftward and compress the locking spring 120. As the support frame 4 continues to move upward and passes over the locking slide 12, the locking slide 12, pushed by the elastic force of the locking spring 120, moves below the locking frame 402, thereby restricting the downward movement of the support frame 4.

[0054] As the upper mold 1 is continuously pressed down, the pressure head 5 applies a preset pressure to the mold 6 and the forming cavity, and the pressure is adjusted according to the press. After the pressing and forming, the raw materials in the inner cavity of the mold 6 and the forming cavity form a whole brick body.

[0055] When the upper mold 1 is reset upward, the return spring 301 pushes the guide piston assembly 3 downward, causing the lower mold 2 to remain pressed on the flat plate. When the piston rod in the synchronous piston cylinder 7 enters the inner cylinder 701, it squeezes the hydraulic oil in the inner cylinder 701 and forces the piston rod of the adjustment piston cylinder 8 to be pushed outward. The pushed-out piston rod drives the connecting frame 10 to move to the left, forcing the mold 6 and the forming cavity to move relative to each other, and using the relative shearing between the two to achieve brick cutting until the mold 6 moves to the left limit. At this time, the height of the brick body is consistent with the height of the forming cavity, that is, the thickness of the brick body after molding is consistent. When the mold 6 is completely separated from the forming cavity, as the mold 6 moves to the left, the bracket on the mold 6 will hit the shift telescopic rod 11 and push it to the left. When the mold 6 and the forming cavity are separated, the shift telescopic rod 11 will also drive the locking slide 12 away from the support frame 4, thereby releasing the movement restriction of the support frame 4. The support frame 4 is pushed by the elastic force of the demoulding spring 401 to make the pressure head 5 move downward, and the pressure head 5 reaches the forming cavity. As the upper mold 1 drives the lower mold 2 upward, the pressure head 5 pushes the brick body in the forming cavity until the upper mold 1 moves up to the top limit. The solenoid valve 702 opens, allowing the hydraulic oil in the inner tube 701 to flow back into the inner cavity of the synchronous piston cylinder 7, and the return spring 301 pushes the guide piston assembly 3 downward until the entire device returns to its initial state.

[0056] It can be seen that the second embodiment can press the building materials into thicker bricks according to the mold 6. Before the bricks are demoulded, the bricks are cut according to the mold 6 to ensure that the thickness of the bricks finally output from the forming cavity is consistent.

[0057] Example 3 is a supplement to Example 2. Please refer to Figure 2 and Figure 4 It can be seen that an anti-reverse seat 9 located on one side of the connecting frame 10 is fixedly installed on the piston rod of the adjusting piston cylinder 8. The anti-reverse seat 9 is conical in shape and is coaxially connected to the piston rod of the adjusting piston cylinder 8 to ensure that when the piston rod moves, it can drive the anti-reverse seat 9 to move left and right synchronously. Correspondingly, a positioning fork frame 901 is movably installed at the bottom of the lower mold 2. The positioning fork frame 901 is in a "U" shape, and the piston rod of the adjusting piston cylinder 8 is located on the inner side of the "U". The advantage of this design is that, combined with Figure 2 As shown, when the upper mold 1 drives the ram 5 to complete the downward mold closing and upward movement, the piston rod in the adjustment piston cylinder 8 is pushed to the left. When the anti-reverse seat 9 moves to the left, the outer inclined surface of the anti-reverse seat 9 causes the positioning fork frame 901 to move upward. When the anti-reverse seat 9 completely passes the positioning fork frame 901, the positioning fork frame 901 is downwardly moved by gravity to the bottom plane of the cone of the anti-reverse seat 9. At this time, the locking slide 12 also releases the restriction on the locking frame 402. The demoulding spring 401 is used to push the support frame 4 downward again, so that the ram 5 can push the brick body in the forming cavity downward. During this process, because the positioning fork frame 901 always locks the anti-reverse seat 9, it is forced to prevent it from moving to the right. Therefore, even if the upper mold 1 is subsequently fully moved to the top and the entire body is reset, the positioning fork frame 901 restricts the movement of the anti-reverse seat 9, forcing the mold 6 to remain offset relative to the forming cavity. It is not difficult to see from Example 2 that after the mold 6 cuts off the brick body in the forming cavity, part of the raw material will remain in the mold 6. Restricted by the in-place fork frame 901 and the anti-reversal seat 9, the mold 6 is forced to always be relatively staggered with the forming cavity under normal circumstances, thus avoiding the problem of the remaining raw material in the mold 6 leaking downward from the forming cavity.

[0058] Moreover, when the brick body is prepared again, the lower mold 2 is first moved down and reaches the flat plate, Figure 2 As can be seen in the figure, under normal conditions, the positioning fork 901 extends from the bottom of the lower mold 2. When the lower mold 2 moves downward and presses on the flat plate, the flat plate pushes the positioning fork 901 upward and releases the movement restriction on the anti-reversal seat 9. Subsequently, the mold 6 is pushed by the elastic force of the forming spring 602 to align the mold 6 with the forming cavity again, ensuring that the remaining raw materials in the mold 6 can be reused. The positioning fork 901 can also detect whether there is a flat plate at the bottom of the lower mold 2. Only when there is a bottom plate at the bottom of the lower mold 2 will the positioning fork 901 align the mold 6 with the forming cavity, thus completing the subsequent brick preparation work.

[0059] Combine Figure 2-Figure 4It can be seen that each mold 6 has a buffer cylinder 601 fastened with bolts on the side, and the buffer cylinder 601 is clearance-matched with the pressure head 5. The advantage of this design is that when the mold 6 is staggered with the forming cavity, the buffer cylinder 601 can be aligned with the forming cavity, that is, Figure 3 The state shown in . When the locking slide 12 releases the movement restriction of the locking frame 402, the demoulding spring 401 will quickly push the ram 5 to move downward. However, at this time, after the ram 5 enters the buffer cylinder 601, the airflow inside the buffer cylinder 601 flows out along the gap between the two, thereby damping the downward movement of the ram 5, preventing the ram 5 from descending too quickly and directly colliding with the brick body in the molding cavity, causing the brick body to be deformed by excessive instantaneous impact. In addition, since multiple rams 5 move downward synchronously, the damping coordination between a ram 5 and the buffer cylinder 601 can affect the overall downward speed, ensuring that the ram 5 as a whole can slow down and descend, avoiding the problem of a local ram 5 descending too quickly and still colliding with the brick body.
