In order to solve the problems of low efficiency in the manufacturing process of building materials and the difficulty in demolding the molded material, multiple molding cavities are set on the lower mold to ensure that multiple clay bricks mixed with waste materials can be manufactured at the same time when the mold is closed. Moreover, during the mold closing process, the support frame compresses and stores pressure on the demolding spring. When the mold is opened, the elastic force of the demolding spring pushes the pressure head and ejects the finished product in the molding cavity, ultimately achieving the effect of rapid demolding.

Description

Technical Field

[0001] This invention relates to the technical field of energy-saving building equipment, and in particular to a production mold for energy-saving building materials and its application process. Background Technology

[0002] In the construction industry, high efficiency and energy conservation have always been core objectives. To achieve this goal, researchers have continuously explored and innovated, developing a new type of energy-saving building material. This material is an improvement on traditional clay bricks. Specifically, it is made by mixing a certain proportion of industrial waste into the clay, including but not limited to waste refractory brick particles, fly ash, furnace bottom slag, and stone powder. After special processing, these waste materials are fully integrated with the clay, forming a completely new building material.

[0003] A search revealed that patent CN210820080U discloses a molding device for building material production. The operation of this device is relatively cumbersome. To begin using the device, the upper pressure plate must first be removed. Then, the connecting rod, fixing sleeve, and support plate are adjusted to the appropriate positions using the fixing ring to ensure the molding frame can be completely placed on the connecting rod and support plate. Next, the jack is used to push the lower hydraulic rod to the appropriate position on the molding frame, at which point concrete is filled into the molding frame. After the concrete filling is complete, the upper pressure plate is placed back into the filled molding frame, and the upper hydraulic rod is activated to extend downwards. When the upper hydraulic rod extends to its maximum length, the lower hydraulic rod is also extended to make the entire concrete mold more compact, ensuring the molding effect.

[0004] This reveals significant shortcomings in the current molding process of energy-saving building materials. On one hand, frequent replacement of different molding frames is required, which not only increases the workload of operators but also significantly reduces manufacturing efficiency, extending the production cycle and failing to meet the demands of large-scale production. On the other hand, the increased adhesion between the energy-saving building material and the molding frame under pressure makes demolding difficult, hindering the smooth removal of the molded material and potentially causing damage during demolding, thus increasing production costs and scrap rates. Summary of the Invention

[0005] This invention proposes an energy-saving building material production mold and its application process, which has the advantages of multiple molding cavities and elastic demolding, aiming to effectively solve the problems of low efficiency in the manufacturing process of building materials and the difficulty in demolding the molded material mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving building material production mold, comprising: an upper mold and a lower mold, which are restricted to relative vertical movement by a guide piston assembly; a return spring is provided on the outer side of the piston rod of the guide piston assembly to achieve relative separation between the upper and lower molds; a support frame is installed at the bottom of the upper mold, which is pushed downward by a demolding spring, and a pressure head is fixedly installed at 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 extrudes the raw material in the forming cavity to produce bricks; a synchronous piston cylinder is installed on one side of the lower mold surface, 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 to the inner side of the inner cylinder; an electromagnetic valve for controlling the on / off state 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 bricks are produced, the upper mold drives the lower mold to move upward, the piston rod of the synchronous piston cylinder extrudes the lubricating oil in the inner cylinder, causing the lower mold to move upward synchronously with the upper mold, and the pressure head is pushed into the forming cavity by the spring force of the demolding spring to eject the bricks.

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

[0008] Furthermore, a molded die connected by a bracket is movably mounted on the surface of the lower mold, and a forming spring is provided between the surface of the lower mold and the molded die. The molded die and the forming cavity are aligned by the elastic force of the forming spring. An adjusting piston cylinder communicating with the inner cylinder is fixedly mounted on the side of the lower mold, and the piston rod of the adjusting piston cylinder drives the molded die to move synchronously by the connecting frame, thereby controlling the alignment / misalignment of the molded die and the forming cavity. A locking frame is fastened to the end of the support frame, and a locking slide is movably mounted on the bottom of the upper mold by the locking spring. The locking slide can restrict the downward movement of the locking frame.

[0009] Furthermore, a displacement telescopic rod is securely installed at the bottom of the locking slide. The bottom end of the displacement telescopic rod is movably installed on the surface of the lower mold. When the bracket on the mold pushes the displacement 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-sectional shape of the locking frame is "L".

[0011] Furthermore, an anti-reverse seat is fixedly installed on the piston rod of the adjusting piston cylinder, and a positioning fork is movably installed at the bottom of the lower mold to restrict the movement of the anti-reverse seat.

[0012] Furthermore, the anti-reverse seat is cone-shaped.

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

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

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

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

[0017] S3. The press pushes the upper die downward, and the lower die contacts the flat 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 mold drives the support frame to move downwards, the pressure head presses the forming mold cavity, the support frame compresses the demolding spring to its limit, and after the pressure head in the upper mold applies the required pressure to the forming mold cavity, the demolding spring is compressed, and the piston rod of the synchronous piston cylinder disengages from the inner cylinder.

[0019] S5. The press drives the upper mold 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 mold always presses the flat plate tightly. After the piston rod enters the inner cylinder, the upper mold drives the lower mold to move upward synchronously. The press head is pushed out of the forming mold cavity by the elastic force of the demolding spring, realizing demolding.

[0020] S6. After the upper die moves to the top, the solenoid valve connects the inner cylinder and the inner cavity of the synchronous piston cylinder. The hydraulic oil flows back into the inner cavity of the synchronous piston cylinder, and under the push of the return spring, the whole thing returns to the normal position, waiting for the next stamping.

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

[0022] This invention provides a mold for producing energy-saving building materials and its application process. The lower mold portion of the mold is equipped with multiple forming cavities. This design allows for the efficient simultaneous production of multiple clay bricks mixed with industrial waste during a single 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] During the mold closing process, the support frame plays a crucial role. As the mold closes, the support frame compresses and stores pressure on the demolding spring. When the molding process is complete and the mold needs to be opened, the previously compressed and stored pressure spring releases its stored force, pushing the pressure head in a stable and powerful manner. Under the action of the spring force, the pressure head evenly and smoothly ejects the molded clay brick from the molding cavity. The entire demolding process is clean and efficient, requiring minimal manual intervention, significantly shortening the demolding time and ultimately achieving a fast and efficient demolding effect. This effectively solves the problems of difficult and inefficient demolding with traditional molds, providing 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] Example 1: The present application proposes an energy-saving building material production mold that uses industrial waste as raw material for manufacturing bricks, so that the waste plays a reinforcing role in the brick blank, thereby improving the compressive strength of the brick.

[0035] In application, clay is used as the main raw material to provide the basic structure and plasticity of the brick. A certain proportion of waste materials (such as waste refractory brick aggregates, fly ash, furnace bottom slag, stone powder, etc.) are crushed and mixed with clay to form a blank with a certain degree of plasticity. The manufactured material is then fed into the production mold described in this application for shaping.

[0036] Specifically, in combination Figure 1 and Figure 2 As can be seen, the entire device consists of two main parts: an upper mold 1 and a lower mold 2. During application, the upper mold 1 can be fastened to the press using the pre-drilled lug holes at the top. The press drives the upper mold 1 to move up and down, thereby bringing the upper mold 1 and the lower mold 2 closer together, which is the mold closing process.

[0037] The lower mold 2 has guide piston assemblies 3 fastened to its four corners using flanges. The piston rods in the guide piston assemblies 3 are fixedly connected to the upper mold 1. This design not only ensures that the upper mold 1 and the lower mold 2 can only move relative to each other vertically, but also utilizes the limited extension length of the guide piston assemblies 3 so that after the piston rod is fully extended from the guide piston assemblies 3, the upper mold 1, continuing to move upward, can drive the lower mold 2 upward using the guide piston assemblies 3. A return spring 301 is installed between the top of the guide piston assembly 3 and the bottom surface of the upper mold 1, sleeved on the outside of the piston rod. Under normal conditions, the return spring 301 pushes the lower mold 2, forcing it to always tend to move away from the upper mold 1.

[0038] The bottom of the upper mold 1 has a support frame 4 that is guided and installed using multiple telescopic rods. Figure 6 As can be seen, a release spring 401 located on the outer side of the telescopic rod connects the support frame 4 and the upper mold 1. Under normal conditions, the support frame 4 is pushed downwards by the elastic force of the release spring 401 and guided by the telescopic rod, causing the telescopic rod to extend to its maximum length. Furthermore, multiple pressure heads 5 are bolted to 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 practical applications, the number of pressure heads 5 is not limited to this and can be adjusted adaptively according to actual needs.

[0039] Correspondingly, from Figure 3 As can be seen, the lower mold 2 has a forming cavity on its surface corresponding to the pressure head 5, that is... Figure 3 As shown in section A, when the upper mold 1 moves downward, the pressure head 5 applies pressure to the forming mold cavity, thereby extruding and molding the material in the forming mold cavity, thus completing the production of multiple energy-saving clay bricks in one mold closing operation.

[0040] To facilitate the removal of the finished bricks from the molding cavity, combined with Figure 1 and Figure 5As can be seen, a synchronous piston cylinder 7 is bolted to one side of the lower mold 2 surface, and an inner cylinder 701 coaxially arranged with it 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 to the inner side of the inner cylinder 701. Figure 5 It can be seen that the inner cylinder 701 is connected to the inner cavity of the synchronous piston cylinder 7 via its bottom. 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 located above the piston rod are isolated 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 the 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, so as to realize the mutual flow of hydraulic oil between the two.

[0041] In practical applications, based on Figure 5 As can be seen, the top of the synchronous piston cylinder 7 has an oil filling port, which can be elastically sealed or connected to the oil tank. Hydraulic oil can be added to the inner cavity of the synchronous piston cylinder 7 through the oil filling port.

[0042] Under normal conditions, the upper mold 1 is fixed on the press. When the press lifts the upper mold 1, the guide piston assembly 3 can drive the lower mold 2 to lift 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. Figure 5 The location shown.

[0043] When making bricks, a flat plate needs to be placed below the lower mold 2 and directly below the forming cavity. This allows the formed bricks to be stacked on the flat plate, which can then be moved using forklifts or other equipment. Afterward, when the press pushes the upper mold 1 downward, the lower mold 2 at its bottom will contact the flat plate first.

[0044] The raw materials for preparing the bricks are added to the molding cavity. As the upper mold 1 descends, the upper mold 1 and the guide piston assembly 3 compress and store force on the return spring 301. During this process, the piston rod of the synchronous piston cylinder 7 descends synchronously from... 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 unidirectional flow of hydraulic oil from the lower chamber to the upper 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 downwards, the pressure head 5 on the support frame 4 eventually presses into the molding cavity. Due to the continuous downward movement of the upper mold 1, the pressure applied by the pressure head 5 to the molding cavity also increases. During this process, the support frame 4 simultaneously compresses the demolding spring 401 until it reaches its limit. Finally, as the pressure head 5 in the upper mold 1 applies the required pressure to the molding cavity, the demolding spring 401 is compressed, and the piston rod in the synchronous piston cylinder 7 disengages from the inner cylinder 701.

[0046] After the raw material is extruded and formed in the molding cavity, 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 to move upward and approach 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 pressed tightly on 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. Therefore, the upward movement of the upper mold 1 will drive the lower mold 2 to move upward synchronously. However, the press head 5 is still inclined to move downward due to the force of the demolding spring 401. As the lower mold 2 continues to move upward, the press head 5 is pushed out of the molding cavity by the force of the demolding spring 401, ensuring that the brick in the molding cavity is easily demolded. When the upper die 1 moves to the top, the inner cylinder 701 and the inner cavity of the synchronous piston cylinder 7 are connected by the solenoid valve 702. The hydraulic oil in the inner cylinder 701 flows into the inner cavity of the synchronous piston cylinder 7. The return spring 301 pushes the whole to return to the normal position and waits for the next stamping.

[0047] After molding, the brick blanks need to be dried to remove excess moisture. Then, the dried brick blanks are placed in a kiln for firing. The firing temperature and time must be strictly controlled according to the properties of the raw materials and product requirements. During firing, the clay and waste materials in the brick blanks undergo physicochemical changes, forming bricks with a certain strength and durability. The firing temperature is usually set within the range of 950℃-1300℃, and the firing time is 20-24 hours.

[0048] After firing, the bricks undergo quality inspection, including indicators such as appearance quality, dimensional accuracy, compressive strength, and water absorption rate. 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 still require dimensional inspection later, it can be seen from the above manufacturing process that the current bricks are mainly pressed into shape in a molding cavity. Their dimensions, such as length and width, are relatively stable due to the constraints of the molding cavity, but their thickness and height are affected by the amount of raw material input. The instability of the raw material input is influenced by many factors, such as uneven mixing of raw material particles, inaccurate metering equipment, and uneven feeding speed.

[0050] To prevent such problems from occurring, this second embodiment combines... Figure 2 and Figure 3 As can be seen, mold 6 is movably mounted on the surface of the lower mold 2, 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 its left limit, the mold 6 and the forming cavity are offset from each other; similarly, when the mold 6 moves to its right limit, the forming cavity and the mold 6 are aligned. Under normal conditions, since the lower mold 2 is equipped with a forming spring 602 mounted on its base, the end of the forming spring 602 abuts against the mold 6, and the forming spring 602 pushes the mold 6 and the forming cavity to always be in a relatively aligned state.

[0051] from Figure 1 , Figure 4 and Figure 5 It can be seen that the lower mold 2 has an adjusting piston cylinder 8 fixedly mounted on its side via a hydraulic cylinder bracket. The adjusting piston cylinder 8 is connected to the inner cavity of the inner cylinder 701 via a hydraulic oil pipe. A connecting frame 10 is fixedly mounted on the outer side of the piston rod of the adjusting piston cylinder 8. The connecting frame 10 is fixedly connected to the bottom of the mold 6. When the piston rod of the adjusting piston cylinder 8 moves back and forth, 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 It can be seen that the support frame 4 has a locking frame 402 bolted to its end, and the cross-sectional shape of the locking frame 402 is "L". Correspondingly, a locking slide 12 is movably installed at the bottom of the upper mold 1, and a locking spring 120 is connected between the locking slide 12 and the upper mold 1. The locking slide 12 is pushed by the elastic force of the locking spring 120, which forces it to move towards the locking frame 402. The side shape of the locking slide 12 is approximately "Z" shaped, and the bottom is provided with a slope. Therefore, when the locking slide 12 moves above the support frame 4, when the support frame 4 pushes the locking frame 402 towards the locking slide 12, the upward-moving locking frame 402 can push the locking slide 12 to compress the locking spring 120 according to the slope. When the locking frame 402 passes the locking slide 12, it is pushed by the elastic force of the locking spring 120 to move the locking slide 12 below the locking frame 402, thereby restricting the downward movement of the locking frame 402. Furthermore, a displacement telescopic rod 11 is securely mounted on the bottom of the locking slide 12, and the bottom end of the displacement 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 displacement telescopic rod 11, and the displacement telescopic rod 11 will drive the locking slide 12 to compress the locking spring 120 in sync.

[0052] In practical applications, under normal conditions, the forming spring 602 pushes the mold 6 to move to the right limit, and at the same time, the locking spring 120 pushes the locking slide 12 to move to the right limit as well.

[0053] Direction Reference Figure 2 Structural Reference Figure 4 and Figure 5As shown, when the press drives the upper mold 1 downward, the lower mold 2 will press onto the flat plate first. At this time, since the mold 6 and the forming cavity are aligned, the raw material can be directly input into the mold 6. After the raw material is delivered, it is pressed downward by the upper mold 1. Consistent with the description in Embodiment 1, when the upper mold 1 pushes the press head 5 downward, the press head 5 is pressed into the mold 6. At this time, the press head 5 simultaneously presses and shapes the raw material in the mold 6 and the forming cavity. After the press head 5 is blocked from moving downward, the support frame 4 will squeeze the demolding spring 401, causing the support frame 4 to move relatively closer to the upper mold 1. During this process, the support frame 4 will move relatively closer to the locking slide 12, and use the support frame 4 to push the inclined surface of the locking slide 12, causing the locking slide 12 to move to the left and press the locking spring 120. When the support frame 4 continues to move upward and passes the locking slide 12, the locking slide 12, pushed by the elastic force of the locking spring 120, moves to below the locking frame 402, thereby restricting the downward movement of the support frame 4.

[0054] As the upper mold 1 continues to press down, the press head 5 applies a preset pressure to the mold 6 and the forming cavity, which is adjusted according to the press. After pressing and forming, the raw material in the inner cavity of the mold 6 and the forming cavity constitutes a whole brick.

[0055] When the upper mold 1 returns to its original position, the return spring 301 pushes the guide piston assembly 3 downward, causing the lower mold 2 to remain pressed against 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 adjusting piston cylinder 8 to push 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. By utilizing the relative shearing between the two, the brick is cut off until the mold 6 moves to its left limit. At this time, the height of the brick is consistent with the height of the forming cavity, that is, the thickness of the formed brick is consistent. When the mold 6 completely separates from the forming cavity, during the leftward movement of the mold 6, the bracket on the mold 6 will abut against the displacement telescopic rod 11 and push it to move to the left. After the mold 6 and the forming cavity separate, the displacement telescopic rod 11 will also drive the locking slide 12 away from the support frame 4, thereby releasing the movement restriction on the support frame 4. The support frame 4 is pushed by the elastic force of the demolding spring 401, which causes the pressure head 5 to move downward. The pressure head 5 touches the molding cavity, and as the upper mold 1 drives the lower mold 2 to move upward, the pressure head 5 pushes the brick in the molding cavity out. After the upper mold 1 moves to the top limit, the solenoid valve 702 opens, allowing the hydraulic oil in the inner cylinder 701 to flow back into the inner cavity of the synchronous piston cylinder 7. The return spring 301 pushes the guide piston assembly 3 downward until the entire device returns to the initial state.

[0056] It can be seen that, according to the mold 6, the building material can be pressed into a brick with a large thickness. Before the brick is demolded, it is also cut according to the mold 6 to ensure that the thickness of the brick output from the molding cavity is consistent.

[0057] Example 3 is a supplement to Example 2; please refer to [link / reference]. Figure 2 and Figure 4 It can be seen that an anti-reverse seat 9 is fixedly installed on the piston rod of the adjusting piston cylinder 8, located on one side of the connecting frame 10. The anti-reverse seat 9 is conical in shape and is coaxially connected to the piston rod of the adjusting piston cylinder 8, ensuring that the anti-reverse seat 9 can move synchronously left and right when the piston rod moves. Correspondingly, a positioning fork 901 is movably installed at the bottom of the lower mold 2. The positioning fork 901 is U-shaped, and the piston rod of the adjusting piston cylinder 8 is located on the inner side of the U-shape. The advantage of this design is that it combines... Figure 2 As shown, when the upper mold 1 drives the pressure head 5 to complete the downward pressing and mold closing and move upward, the piston rod in the adjusting 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 will cause the positioning fork 901 to move upward. After the anti-reverse seat 9 completely passes the positioning fork 901, the positioning fork 901 will move downward under gravity and move 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 demolding spring 401 pushes the support frame 4 to press down again, thereby realizing that the pressure head 5 pushes the brick in the forming mold cavity downward. During this process, since the positioning fork 901 always locks the anti-reverse seat 9, it forces the anti-reverse seat 9 to be unable to move to the right. Therefore, even if the upper mold 1 moves completely to the top and resets the whole, the positioning fork 901 restricts the movement of the anti-reverse seat 9, forcing the mold 6 to always be relatively misaligned with the forming mold cavity. As can be seen from Example 2, after the mold 6 cuts the brick in the forming cavity, some of the raw material will remain in the mold 6. Due to the restriction of the positioning fork 901 and the anti-reverse seat 9, the mold 6 is forced to always be relatively offset from the forming cavity under normal conditions, thus avoiding the problem of the remaining raw material in the mold 6 leaking downward from the forming cavity.

[0058] Furthermore, when preparing the bricks again, because the lower mold 2 descends first and touches the flat plate, from... Figure 2 As can be seen, under normal conditions, the positioning fork 901 extends from the bottom of the lower mold 2. When the lower mold 2 descends and presses against the flat plate, the flat plate pushes the positioning fork 901 upward, releasing it from the movement restriction on the anti-reverse seat 9. Subsequently, the mold 6, pushed by the forming spring 602, will align with the forming cavity again, ensuring that the remaining material 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] Combination Figure 2-Figure 4It can be seen that each mold 6 has a buffer cylinder 601 fastened to its side by bolts. The buffer cylinder 601 and the pressure head 5 are fitted with a clearance. The advantage of this design is that when the mold 6 is misaligned with the forming cavity, the buffer cylinder 601 can be aligned with the forming cavity. Figure 3 The state is shown in the diagram. When the locking slide 12 releases the movement restriction of the locking frame 402, the demolding spring 401 will quickly push the pressure head 5 downward. However, at this time, since the pressure head 5 enters the buffer cylinder 601, the airflow inside the buffer cylinder 601 flows out along the gap between the two, which dampens the downward movement of the pressure head 5. This prevents the pressure head 5 from falling too fast and directly impacting the brick in the molding cavity, causing the brick to be deformed due to excessive instantaneous impact. Moreover, since multiple pressure heads 5 move downward synchronously, the damping coordination between one pressure head 5 and the buffer cylinder 601 can affect the overall downward speed, ensuring that the pressure heads 5 can all decelerate downward, avoiding the problem of some pressure heads 5 falling too fast and still impacting the brick.
