Description

Technical Field

[0001] This utility model relates to the field of concrete block molds, specifically to a multi-cavity concrete block forming mold. Background Technology

[0002] Concrete block molds are divided into single-cavity and multi-cavity molds. Multi-cavity molds have multiple cavities, allowing multiple blocks to be formed simultaneously in the same production cycle.

[0003] Existing multi-cavity concrete block molding molds primarily rely on air blowing through vents at the bottom of individual cavities for demolding. Each vent corresponds to a blower port at the bottom, requiring the air gun to be repeatedly inserted into different ports to blow out multiple blocks one by one, resulting in extremely slow demolding efficiency. Furthermore, compared to single-cavity molds, which can be placed upside down on the ground and the gas pressure pushes the mold upwards, leaving the blocks on the ground, multi-cavity molds require the mold to be elevated to allow the blocks to detach from the bottom.

[0004] Therefore, a multi-cavity concrete block molding mold is designed, which can demold multiple blocks at once through a single air inlet. During demolding, it is not necessary to raise the mold; the mold can be placed directly upside down on the ground, and the air pressure can be used to lift the multi-cavity molding mold directly upward, thereby improving demolding efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a multi-cavity concrete block molding die to solve the problems described in the background art.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A multi-cavity concrete block molding mold includes a mold box with an open top. Multiple partitions divide the internal space of the mold box into multiple open-top cavities, arranged in a straight line. A main air passage is laterally formed in the bottom wall of the mold box, with both ends sealed within the bottom wall. The main air passage passes through the bottom of each cavity. A first air hole communicating with the main air passage is also formed at the bottom of each cavity. A boss is also provided at the bottom of the mold box. A second air hole communicating with the main air passage for airflow is also formed at the bottom of the mold box. An air pipe connector is fixed to the bottom of the mold box, communicating with the second air hole. Multiple threaded holes are also formed at the bottom of the mold box, communicating with the main air passage. A sealing bolt is screwed into each threaded hole from bottom to top. The sealing bolt, when screwed upwards a certain distance, can block the main air passage. The multiple threaded holes are respectively located upstream of the airflow at the connection between the first air hole and the main air passage of each cavity.

[0008] A further technical solution is that the mold box is a cuboid mold box, the mold cavity is a cuboid cavity, the number of partitions is two, and the number of mold cavities is three.

[0009] A further technical solution is that the first air hole is opened at the center of the bottom of the mold cavity.

[0010] A further technical solution is to make the main airway a long, straight airway.

[0011] A further technical solution is that the main air passage runs directly from one end of the mold box to the other end, and sealing strips are embedded at both ends of the main air passage.

[0012] A further technical solution is that the three mold cavities correspond to three first air holes, namely, first air hole No. 1, first air hole No. 2, and first air hole No. 3. The number of threaded holes is three. The second air hole is located between first air hole No. 2 and first air hole No. 3. A threaded hole is located between first air hole No. 1 and first air hole No. 2, between first air hole No. 2 and first air hole No. 2, and between second air hole No. 3 and first air hole No. 3.

[0013] A further technical solution is that the boss is an annular boss, which is arranged around the bottom edge of the mold box.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. High demolding efficiency: It can demold multiple blocks at the same time, improving demolding efficiency.

[0016] 2. Uniform demolding effect: By setting sealing bolts to adjust the air pressure, for some blocks that have demolded less, the airflow in other mold boxes can be reduced or isolated, so that multiple blocks can be demolded at the same time and evenly.

[0017] 3. High ease of operation: The demolding operator can control the air gun with one hand and adjust the sealing bolt with the other, making it easier to adjust the airflow.

[0018] 4. Low manufacturing cost: The main air passage runs straight from one end of the mold box to the other, with sealing strips embedded at both ends, which facilitates processing and reduces costs; the airflow regulation and coordination design of the threaded hole and sealing bolt reduces the processing difficulty and manufacturing cost of the mold.

Detailed Implementation

[0023] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] See Figures 1 to 3 A multi-cavity 3-concrete block forming mold includes a mold box 1 with an opening at the top.

[0025] Preferably, the mold box 1 is a rectangular parallelepiped mold box 1.

[0026] The mold box 1 is provided with multiple partitions 2 to divide the internal space of the mold box 1 into multiple mold cavities 3 with openings at the top, and the multiple mold cavities 3 are arranged in a straight line.

[0027] Preferably, the mold cavity 3 is a cuboid cavity, the number of partitions 2 is two, and the number of mold cavities 3 is three.

[0028] A main air passage 6 is also horizontally opened in the bottom wall of the mold box 1, and both ends of the main air passage 6 are closed inside the bottom wall of the mold box 1. The main air passage 6 passes through the bottom of each mold cavity 3, and the bottom of the three mold cavities 3 is also provided with a first air hole 4 that connects to the main air passage 6.

[0029] Preferably, the first air hole 4 is located at the center of the bottom of the mold cavity 3.

[0030] Preferably, the main airway 6 is a long and straight airway.

[0031] Preferably, the main air passage 6 extends from one end of the mold box 1 to the other end of the mold box 1, and sealing strips 7 are respectively embedded at both ends of the main air passage 6.

[0032] The bottom of the mold box 1 is also provided with a boss 5.

[0033] Preferably, the boss 5 is an annular boss 5, which is arranged around the bottom edge of the mold box 1.

[0034] The bottom of the mold box 1 is also provided with a second air hole 10 for introducing airflow, which is connected to the main air passage 6. An air pipe connector 11 is also fixed to the bottom of the mold box 1, and the air pipe connector 11 is connected to the second air hole 10. The bottom of the mold box 1 is also provided with three threaded holes 8, which are connected to the main air passage 6. A sealing bolt 9 is screwed into the threaded hole 8 from bottom to top. After the sealing bolt 9 is screwed upward a certain distance, it can block the main air passage 6.

[0035] The three threaded holes 8 are respectively located upstream of the airflow at the connection between the first air hole 4 and the main air passage 6 of the three mold cavities 3.

[0036] Specifically, each of the three mold cavities 3 corresponds to one of the first air holes 4, namely, the first air hole 4 No. 1, the first air hole 4 No. 2, and the first air hole 4 No. 3. There are three threaded holes 8. The second air hole 10 is located between the first air hole 4 No. 2 and the first air hole 4 No. 3. There is one threaded hole 8 between the first air hole 4 No. 1 and the first air hole 4 No. 2. There is one threaded hole 8 between the first air hole 4 No. 2 and the second air hole 10. There is one threaded hole 8 between the second air hole 10 and the first air hole 4 No. 3.

[0037] Working principle of this utility model:

[0038] When using this device for demolding, place the mold box 1 upside down on the ground and connect the air gun directly to the air pipe connector 11 to blow air into the second air hole 10.

[0039] It should be noted that there are various ways to implement the tracheal connector 11, such as using a quick-connect fitting, a rotary fitting, or a rotary snap-fit ​​fitting. These are all common technical means in the field. Therefore, this disclosure does not limit the specific implementation of the tracheal connector 11. Those skilled in the art can choose the appropriate tracheal connector 11 based on the implementation methods in the existing technical solutions.

[0040] When the airflow enters the second air hole 10, it enters the main air channel 6 along the second air hole 10, and then enters the three first air holes 4 through the main air channel 6. The airflow is blown into the mold cavity 3 from the three first air holes 4. As the gas pressure continues to increase, the gas thrust between the concrete blocks in the three mold cavities 3 and the bottom of the mold box 1 continues to increase. Under the reaction force of the ground, the concrete blocks do not move, and the mold box 1 is pushed upward by the gas. With the help of the demolding personnel, the air pipe or air gun is lifted upward, thereby realizing the function of demolding the mold box 1 upward. This enables the demolding of multiple blocks at one time, improving demolding efficiency.

[0041] In the actual demolding process, occasionally some blocks will be less removed and will be lifted up by the box. At this time, the sealing bolts 9 can be used to adjust the air pressure. By tightening the sealing bolts 9, the amount of airflow entering each mold box 1 can be reduced or isolated, so that the blocks that are less removed can obtain more air pressure, thereby achieving the function of multiple blocks being removed evenly at the same time.

[0042] Furthermore, in this design, the demolding operator can control the air gun with one hand and adjust the sealing bolt 9 with the other, which improves the convenience of adjusting the airflow.

[0043] Meanwhile, in the design disclosed herein, the main air passage 6 extends directly from one side wall of the mold box 1 to the other side wall, and sealing strips 7 are embedded at both ends of the main air passage 6. This design facilitates the processing of the main air passage 6, which can be completed in one go with a long drill bit. Then, the sealing strips 7 with glue are inserted to seal both ends of the main air passage 6, reducing the manufacturing cost of the mold.

[0044] The airflow regulation design of the threaded hole 8 and the sealing bolt 9 also facilitates the processing design of this mold, reducing the processing difficulty and manufacturing cost of the mold.

[0045] The boss 5 in this design provides operating space for the sealing bolt 9 and the air pipe connector 11.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
